New research reveals a possible mechanism allowing “black stars” and “gravastars” to exist

When giant stars die, they don’t just fade away. Instead they collapse in on themselves, leaving behind a compressed stellar remnant, usually a city-size, superdense ball of neutrons appropriately called a neutron star. In extreme cases, however, most theorists believe an expiring giant star will form a black hole—a pointlike “singularity” with effectively infinite density and a gravitational field so powerful that not even light, the fastest thing in the universe, can escape once falling in. Now a new study is reinvigorating an alternate idea, that objects with names such as “black stars,” or “gravastars,” might exist midway between neutron stars and black holes. If real, these exotic stellar corpses should appear nearly identical to black holes save in one key way—they could not irretrievably swallow light.

There are good reasons to seek such alternatives, because black holes raise a host of theoretical problems. For instance, their singularities are supposedly hidden by invisible boundaries known as event horizons. Throw something into a black hole, and once it passes the event horizon it should be gone—forever—with no hope whatsoever of return. But such profound annihilation clashes with other long-cherished laws of physics that suggest the destruction of information is impossible, including information encoded within anything falling into black holes.

Conceived and developed across the past two decades, in part to sidestep such conundrums, models of black stars and gravastars postulate these objects would lack singularities and event horizons. But questions have lingered as to whether such objects could actually form—and remain stable after they did. New research from theoretical physicist Raúl Carballo-Rubio at the International School for Advanced Studies in Italy provides a novel mechanism that might allow black stars and gravastars to exist.

Carballo-Rubio investigated a strange phenomenon known as quantum vacuum polarization. Quantum physics, the best description yet of how all known subatomic particles behave, suggests reality is fuzzy, limiting how precisely one can know the properties of the most basic units of matter—for instance, one can never absolutely know a particle's position and momentum at the same time. One strange consequence of this uncertainty is that a vacuum is never completely empty but instead foams with so-called “virtual particles” that continuously fluctuate into and out of existence.

The wolf also shall dwell with the lamb,The leopard shall lie down with the young goat,The calf and the young lion and the fatling together;And a little child shall lead them. Isaiah 11:6

The Excel graph and table compares the muzzle velocities of different firearms in feet per second (FPS). The physics of bullets and bodies can be tremendously horrible, as Gina Kolata and C. J. Chivers in the New York Times attests. Maureen Downey in the Atlantic Journal Constitution reports trained police officers have an 18% accuracy rate in a gunfight. Arming teachers is not a solution towards an "armed and polite society": it is the recipe for future bloodbaths, supplied by young bodies.

In the Y2K scare days (they seem mild in comparison to current events), my oldest son was shouted "WHITE POWER" at from the front of our lawn in Cedar Park, Texas by the occupants of a passing pickup truck. It was 1999, and everyone was getting "Apocalypse crazy." I promptly went to a pawn shop and purchased a Gloc 9 mm to protect my wife and his younger brother. I've since sold it. I admit it was a reaction to what for most African Americans is a real and historical evidence-induced fear of a crazed lynch mob. It is dissimilar completely to the irrational fears chronicled in Scientific American by Jeremy Adam Smith: "Why Are White Men Stockpiling Guns?" I can pretty much guarantee it wasn't because some Panther Party member shouted "BLACK POWER" from their front lawns.

If I said my sister's name, you wouldn't find it in a history book. She, like these youth was a part of a movement. It was the reason we have the Civil Rights Act, Voting Rights Act (under attack) and the Fair Housing Act. It was the Civil Rights movement in the 1960's. She was and is my hero. It was a time of lambs becoming lions.

It was the youth then that drove the change in laws, first at the Woolworth counter in Greensboro that eventually got rid of the "whites only"; "blacks only" signs ubiquitous at the time. There were nervous days when she was arrested, hosed, beaten...I just become emotional typing it out. The sacrifices were not trivial then, or now.

I also become emotional when children are killed. We failed them as a nation in Sandy Hook. The imbeciles then and now that labeled the parents and now young citizens as "crisis actors" are the vilest of humanity. They are not to be argued with, but pitied.

It appears the youth have found their voice: in organizing this impressive, symbolic walkout; by organizing the March for Our Lives on the 24th of this month. Also by realizing they have another power: voting. They have promised to vote in 2018 when many will first turn 18, 2020 and thereafter.

If there had not been an assault on their peace at a place they once considered safe, they would be sharing ear buds listening to music, gossiping and arguing on social media apps. They would have looked at Civics as antiquated, something their parents concerned themselves with. Nothing about who was president or which party was in power would have mattered. For the children at Parkland, nothing changed their fortunate and quite privileged lives...except the massacre visited on their doorsteps last Valentine's Day. The irony is like the opioid crisis vs. the crack cocaine epidemic, the difference in approach tends to correlate with zip codes. Black Lives Matter was their most recent prototype for the usage of social media to prove a point.

No more. Without specifically mentioning "intersectionality," their online, in-person and grass roots rainbow campaign has remarkably achieved it.

There will be those who tell them unceremoniously to "shut up." There will be threats both frivolous and genuinely deadly. There may be nervous days, hosing, beatings and worse. Don't listen and don't let them kowtow you. You are STRONGER than you know; you are stronger than THEM - and they KNOW it. Reagan won the youth vote 61 - 30 in the 1980's. They can't do that anymore. Jonathan Chait of NY Magazine says you are younger, more diverse, more liberal and know your power. They - the old, ossified fossils - are dying off, and they are TERRIFIED.

Children - then, and now - will lead us. It is always when lambs are slaughtered, lions are eventually stirred, and roar.

Analog signs have been supplemented with websites. Fliers have been updated to Facebook Live and Snap Chat. They are still marching as did their ancestors. That's what lions do.

10:00 am, children walked out en masse on the one month observance of the massacre when people are usually struggling with restaurant invitations, candies given to sweethearts or lamentations of not having one. 17 minutes for 17 lives lost.

The 15th of February, during African American History Month, they became adults; they became LIONS. You've taken "social justice warrior" from pejorative to movement.

#ENOUGH!...and thank you.

BBC: World renowned physicist Stephen Hawking has died at the age of 76.

He died peacefully at his home in Cambridge in the early hours of Wednesday, his family said.

The British scientist was famed for his work with black holes and relativity, and wrote several popular science books including A Brief History of Time.

There are a myriad of tributes to Professor Hawking from around the world. It is apropos for him, as well as poetic he passed on Pi Day and Albert Einstein's 139th birthday. Both were extraordinary and complicated men.

Less so than the world we live in, where a former campaign manager in France says to a right wing Le Pen crown to where their racism "as a badge of honor." That the president* he helped a foreign government select for us called the nations on the birth continent of the human species as well as Caribbean nations "s--- hole countries."

We are being pushed inexorably from the Age of Enlightenment into the overbearing arms of our lesser angels. Professor Carl Sagan's "candle in the dark" is being snuffed by bigotry, homophobia, misogyny, xenophobia and every "ism" you can modify a noun with. The Dark Ages were about scientific ignorance as well as emotional and irrational fear. Some of us seem determined that those were our "better days."

He wasn't supposed to live beyond his twenties. Perhaps with something like his pluck and determination, we can beat back fascism as he defied the odds of his own existence.

Perhaps...

Si Qubits and Quantum Computers...

A new two-qubit quantum processor that is fully programmable and single electron spins that can be coherently coupled to individual microwave-frequency photons are two of the latest advances in the world of solid-state spin-based quantum computing. The breakthroughs could help in the development of large-scale spin-based processors in the future.

While classical computers store and process information as "bits" that can have one of two logic states – "0" or "1" – a quantum computer exploits the ability of quantum particles or bits (qubits) to be in a "superposition" of two or more states at the same time. Such a device could, in principle, outperform a classical computer on certain tasks, such as factoring large prime numbers and sorting large random lists, thanks to it being massively parallel.

In recent years, researchers have succeeded in making qubits from a number of solid-state materials, including semiconducting quantum dots and superconductors. Semiconductor spin qubits appear to be better for a number of reasons. For one, they last for a relatively long time before decohering (interacting with their environment). They can also be controlled electrically and can be integrated with high density on a chip.

The problem, however, is that it is still difficult to control the state of individual spin qubits and intertwine multiple qubits in a controlled way.

A Facebook post I made responding to some of the president's* supporters wanting a "white history month" (last chance to disengage before the rant):

365 - 28 = 337 freaking days! You freaked out over President Obama when you had 232 years of white male rule that only changed parties. You freaked out on Black Panther, when you had THREE Thor movies. Speaking of which, you freaked out when Idris Elba played Heimdall and Tessa Thompson played Valkyrie in Thor: Ragnarök. You lost it when Kate Mulgrew played Captain Janeway on Star Trek Voyager; you had a conniption fit over Avery Brooks as Commander, then Captain Benjamin Sisko on Star Trek Deep Space Nine and you almost had a Grand Mal seizure over Sonequa Martin-Green on Star Trek Discovery! Don’t let me get started on how the sad/rabid puppies attacked NK Jemisin on having the audacity to WIN the Hugo and Nebula Awards for EXCELLENT science fiction that didn't center around gene spliced clones of Buck Rogers, John Wayne, James T Kirk and Han Solo! In other words, how emotionally butt-hurt do you have to be where ANYTHING that doesn’t involve your culture as front-and-center of the plot line is an all-hands-on-deck existential crisis? Get some therapy and switch to Decaf!

Rant over. Read the title and listen to the embed videos. Definition with ramrod straightened back follows. Blog break during spring break next week and the rest of this one to prep for midterms. \\//_

Definition of negritude (Merriam Webster)

1 : a consciousness of and pride in the cultural and physical aspects of the African heritage

2 : the state or condition of being black

The Harlem Renaissance inspired Negritude. Authors such as Claude McKay and Langston Hughes laid groundwork for black expression. Senghor, Damas and Césaire together drew influence from their work. Other artistic influences were jazz and earlier fin-de-siècle poets such as Rimbaud, Mallarmé and Baudelaire.

Negritude responded to the alienated position of blacks in history. The movement asserted an identity for black people around the world that was their own. For Césaire and Damas, from Martinique and French Guiana, the rupture from Africa through the Atlantic Slave Trade was a great part of their cultural understanding. Their work told of the frustration and loss of their motherland. For Senegalese Senghor, his works focused more on African traditionalism. In ways the assertion of each poet diverges from each other, but the combination of different perspectives is also what fueled and fed Negritude. Black Past dot org: Negritude

Fimmaker Raoul Peck's Oscar-nominated documentary I Am Not Your Negro features the work of the late writer, poet, and social critic James Baldwin. Baldwin's writing explored race, class and sexuality in Western society, and at the time of his death in 1987, he was working on a book, Remember This House. It was never completed, but his notes for that project became the foundation for Peck's I Am Not Your Negro.

Among those notes was a letter J Baldwin wrote to his literary agent, Jay Acton, in 1979. In that letter, he wrote that he wanted to explore the lives of three of his civil rights movement contemporaries and close personal friends: Medgar Evers, Martin Luther King, Jr., and Malcolm X. "I want these three lives to bang against and reveal each other as in truth they did," he wrote, "and use their dreadful journey as a means of instructing the people whom they loved so much who betrayed them and for whom they gave their lives."

Peck had been wanting to make a film about Baldwin for years, but he says it felt like an impossible one to make. When he first read Baldwin's letter, he knew he had the basis for that film. "I had access to those notes, which for me was the real opening I needed to address the film I wanted to make — which was how do I make sure that people today come back to Baldwin and the important writer that he was, and the important words that he have written, and [have] this well-needed confrontation with reality today with words that he wrote 40, 50 years ago?"

The Haitian-born filmmaker has been a fan of Baldwin's writing since he was a teenager. "He helped me understand the world I was in," Peck says. "He helped me understand America. He helped me understand the place I was given in this country."

Your Wall...

Originally published in the evening newspaper, the Winston-Salem Sentinel. The handwriting is my mother's note to her brother, my Uncle James: "This is Reggie. Your nephew. My son." They are both with the ancestors now. RIP - rest in power

This is a photo that should not have happened. Since I volunteer to teach SAT math, I use it as an inspiring story, especially to young women and men that share my same cultural experience. I've posted this photo, or one like it before. It occurred to me I've never told the story behind it.

When I was in the ninth grade at Atkins High School in Winston-Salem, NC, Major Thomas L. May and Sergeant Major Dennis R. Casey - my Army ROTC instructors - invited the Cadet Brigade Commander of Winston-Salem, Forsyth County Schools. Cadet Colonel Wall was tall and lithe, blond-haired and steely blue-eyed; his rank represented by three shiny diamond-shaped metal insignias on his uniform collar, or in many cases his shirt collar. He spoke to each ROTC class and conducted a rank inspection. During class time after the inspection, I approached the-then Brigade Commander, impressed with his ribbons and medals, not knowing what else to say with a nonchalant question: "how did you achieve your rank?" I thought I was making a rhetorical statement. He took it as I was asking for me: "YOUR KIND will never get to this rank!" he exclaimed.

"Your kind"...I was dumbfounded and silent with rage. "Your kind" was an insult to my mother and father, whom he had never met. "Your kind" castigated my sister, who as a young woman put her life on the line in the Civil Rights movement a decade before our encounter. "Your kind" damned generations after me, for all time. "Your kind" was like the faux "curse of Ham" Jedi mind tricked on my culture, or myths of angels in the war of heaven coming to Earth as either "light-skinned or dark-skinned babies" depending on some measure of valor opined, but not observed. "Your kind" labeled my sons and their future children as failures before they landed on the planet! I was fourteen, but suddenly I was in an instant thrust into an adult world of privilege, power and prejudice.

My instructors looked embarrassed and tried to move to another subject. My friends were also silent, and somewhat disappointed that I didn't follow my first instincts and deck him. Even then, Juvenal detention was an ever-pending reality for any African American male teenager that stepped out-of-line. I fumed silently. I discussed the affront with my parents that night at home, who were genuinely and understandably upset. They asked me if I wanted them to call the school, or visit the principal. I said no. I wanted to handle this one myself. My mother, in her gentle way reminded me of Philippians 4:13.

Colonel Wall returned the next day. It was now, or never...

"Do you read?" I asked. (I noticed I didn't address him as Colonel Wall anymore.)

"Of course I do," he said.

"In three years," I challenged, "I will be wearing your rank!"

"I doubt that very seriously," he scoffed.

"Watch me!" At that point, hitting him resurrected, albeit briefly.

I took that as a challenge to prove him wrong. I studied harder than I had ever before. His name became a metaphor for any barrier presented I had to overcome. I was up to that point indifferent to academics until my encounter. I routinely wheezed and coughed when I ran on our track during gym. I worked on my running, push ups, sit ups, weight training; I improved. I joined the pistol, rifle and orienteering (ranger) teams. I worked on my public speaking skills, presenting for an Air Force ROTC inspection at North Forsyth High School, where I matriculated after the 10th grade due to forced busing. I memorized what amounted to twenty-two ribbons, one medal and two shooter's badges I could identify without looking down at the pocket they were pinned on. Three years later, I went before the city board that decided which young man or woman would be the next Brigade Commander for the 1979-1980 school year. I became that person. It was not without challenge, as the Ku Klux Klan (or, someone affiliated with them) apparently didn't take too kindly to my ascent. The Greensboro massacre was fresh on my mind, months into my tenure. I was sent threats to "not show up, or else" on a poorly written note left in my locker regarding our annual Brigade Review in Bowman Gray Stadium. I ignored whoever that cowardly cretin was too. I had participated in the annual parade as a cadet. I was going to as its commander.

Later in life, I was a commissioned 2nd Lieutenant in the Air Force, having completed my matriculation at NC A&T State University in Engineering Physics. The former Cadet Colonel Wall had gone in the Army, enlisted. I saw him at Bergstrom Air Force Base...and he saw me (though from his body language, he tried to avoid me). By the US Constitution we both swore to protect and defend, he by law HAD to salute me. We said nothing, other than me saying..."carry on, Sergeant."

"That was a good story," my SAT student said. I summed the moral of my personal tale to the group of young men and women that you'll have obstacles placed in the way of your goals. The key is to ignore the erstwhile opinions of "your walls" and overcome them. They at least nodded they were paying attention. I smiled. They are "my kind."

Diaspora Spirituality...

We run the gamut: from A - Z, the diaspora has a rich and diverse spirituality. The Baptist Church is the oldest construct, but Mother Emanuel AME could be one of the oldest black churches, famous way before the recent terrorism in Charleston:

Just days after the tragic shooting at Emanuel AME Church in Charleston, S.C., last year, the pews at Emanuel AME were filled for Sunday service. A black cloth was draped over the chair where Emanuel's pastor, state Sen. Clementa Pinckney, should have been sitting.

Holding worship in the church sanctuary — while its basement was still a fresh crime scene — served as a way for the congregation to move forward while acknowledging the deaths of nine of its own. [1]

My wife and I had just passed this church on a quaint carriage ride through the city. We were told Emanuel had been visited by Martin Luther and Coretta Scott King as well as other luminaries of the Civil Rights movement. We also passed near the shore, the auction area, what looked like a long covered porch...where slaves, my ancestors were sold.

My great-grandfather and his brother helped form New Light Beulah Baptist Church in Congaree, South Carolina in 1867; I've been a member of Bethel Baptist in Wappingers Falls, New York, the founders building a stop on the Underground Railroad. I'm a current member of Providence Baptist, the oldest African American church in Greensboro, starting in 1866. Tina Turner and a few African Americans are practicing Buddhists. There are several sites dedicated to atheism and agnosticism, modified by the adjective "black." Santeria and Voodoo are slightly different than Wiccan, but many participate in it. There are Nation of Islam, Shia, Sufi, Sunni and Orthodox Muslims. There are officially black millennial "nones." Goldie Taylor wrote an excellent exploratory piece in the Daily Beast, reluctantly joining a side of this diversity.

The intersection of the Venn diagram is a people that were counted as less, supposed to be conquered and mute about the occasional brutality visited upon it; we found ways to construct community and survive. I recall a scene in the movie Black Panther where Lupita Nyong o (Nikia) and Danai Gurira (General Okoye) and other warriors in the Dora Milaje did a celebratory dance on the coming coronation of T'Challa (Chadwick Boseman) as king. I thought about the ease of the rhythm before me on the film that communicated a freedom I don't feel most of the time. It was a freedom of having a culture, customs, a language and history uninterrupted by human trafficking, middle passage and forced miscegenation. It was a moment in the action movie that raised an envy; a longing. Much has been said the movie expressed Afrofuturism, itself a branch of Sun Ra, preceding George Clinton and Parliament Funkadelic with his video "Space Is The Place," itself an homage to the spiritual "swing low, sweet chariot, coming forth to carry me home," a "coded 100" song giving instructions to potential runaway slaves; itself a longing and knowing the brutality of the American system was not a desired, permanent state for any thinking people. Whether by Harriet Tubman, alien tech, Wakanda or ectoplasm, an escape is still an escape.

Each diverse expression of agnosticism, atheism, Buddhism, theism and nature spirit traditions are all exercising under a construct of white supremacy and navigating it. Even in higher education, especially when in the numerical as well as cultural minority, we must as Dr. Holbrook points out, develop Survival Strategies. We have been and are subject to terrorism, fire bombings, lynching, castration and murder by citizens and judicial policy - either the state on a gurney or in a blue uniform. We are demonized for our skin color, our worship patterns, or neighborhoods like Native American reservations we were forced in through redlining and who we choose to love by WASP convention. Under the rubric of oppression, we've constructed the blues, dance, gospel, jazz and literature; their immediate children being disco and hip hop, the latter having a resurgence of relevance with Jay Z and Kendrick Lamar speaking verse like spoken word artists tackling relevant subjects and divergent expressions of asking the universe "who am I?"

The Rev. James Cone is the founder of black liberation theology. In an interview with Terry Gross, Cone explains the movement, which has roots in 1960s civil-rights activism and draws inspiration from both the Rev. Martin Luther King, Jr. and Malcolm X, as "mainly a theology that sees God as concerned with the poor and the weak."

Cone explains that at the core of black liberation theology is an effort — in a white-dominated society, in which black has been defined as evil — to make the gospel relevant to the life and struggles of American blacks, and to help black people learn to love themselves. It's an attempt, he says "to teach people how to be both unapologetically black and Christian at the same time." [2]

There is an old proverb that says something to the effect a ship sailing a particular course can change its destination by altering its original coordinates by a few degrees. It is this degree of separation if you will that makes the notion that we would think the same, preach the same, worship the same under the anvil of white supremacy is "quaint" to say the least. It is why Reverend Jeremiah Wright's jeremiad was sampled in sound bite, purposely taken out of context to foil an interruption in the highest symbol of white supremacy in 232 years of the republic. Bill Moyers corrected the record with an interview with Dr. Wright. (Coincidentally, Baruch - the Hebraic spelling of Barack - was an aid and friend to the prophet Jeremiah.) It is why in the outpouring of grief for Michael Jackson, commentators marveled at how "long the service was taking," when everyone spoke about our new ancestor. The same was repeated for Prince. In each instance, it showed a lack of experience with a part of the American fabric that was supposed to be seen, not heard; ruled and not [ever] to govern.

Sadly, millennials are falling away from that due to disappointment in leaders more interested in leer jets, access to political power and bling than service to the community, or helping with their burgeoning student loans. I share their disappointment, but not their lack of hope. Dr. William Barber's Moral Mondays that has become Breech Repairers and John Pavlovitz's Stuff That Need to be Said are noted exceptions to these blanket observations.

I see another convergence between the millennials in the recent Florida shooting, the murdered kindergarten students at Sandy Hook, Black Lives Matter and Me Too. The Civil Rights movement was led primarily by people we see now as seasoned, but during the time of hoses, dogs bits and billy clubs were the youth of their day. The youth of this day are connected via social media primarily to each other, typically sharing innocuous things like selfies and food eaten. Now more than ever, they need to use that power - and it is considerable - to bring about the change they seek; to BE "the change they seek":

“Change will not come if we wait for some other person, or if we wait for some other time. We are the ones we've been waiting for. We are the change that we seek.”

― President Barack Obama, Good Reads

The sixties, seventies, eighties and early nineties lulled all of us into apathy. Entertainment like "I Spy"; "Star Trek"; "The Courtship of Eddie's Father"; "The Cosby Show"; "Miami Vice" showed people of different cultures and different worlds working together in a spy agency or on a spaceship; a single, widowed father raising his son alone, a professional couple raising five children and a cop duo that changed the television genre into episodic music videos. We were lulled into thinking - as Dr. Maya Angelou opined hopefully after the election of President Obama - "America had 'grown up.'" In 2016, our Democratic Republic put on its training wheels again, following the dueling pied pipers of a Russian oligarch and a dimwitted demagogue.

Instead of waiting on their parents, it's time for the children to lead US, not to a promised land, but ever closer to a more perfect union.

May the ancestors be pleased, give you strength, and guide you all. We will follow.

Dr. Claudia Alexander, In Memoriam...

Claudia Alexander: 1959 - 2015

Topics: African Americans, Civil Rights, Diaspora, Diversity, Diversity in Science, History, NASA, Science Fiction, Women in Science

As a research scientist, she inspired a generation, especially young women, to seek careers in science, technology, engineering and math.

This weekend was one of great excitement for the planetary science community as the New Horizons spacecraft moved in on Pluto following decades of hard work. But that optimism took on a somber tone Saturday as news quickly traveled that pioneering scientist Claudia Alexander had died at age 56. Friends and family writing online tributes reported she suffered from breast cancer, but no official cause of death was given.

Alexander was an employee of the Jet Propulsion Laboratory (JPL) and the final project manager for NASA’s Galileo mission. But her public profile rose dramatically last fall due to her duties as project scientist for NASA’s role in the European Space Agency’s Rosetta mission to Comet 67P/Churyumov-Gerasimenko.

"The passing of Claudia Alexander reminds us of how fragile we are as humans but also as scientists how lucky we are to be part of planetary science,” James Green, director of NASA's Planetary Science Division, said in a statement. “She and I constantly talked about comets. Comet Churyumov-Gerasimenko in particular. She was an absolute delight to be with and always had a huge engaging smile when I saw her. It was easy to see that she loved what she was doing. We lost a fantastic colleague and great friend. I will miss her." [1]

The C. Alexander Gate, located on the smaller lobe of Comet 67P/C-G, has been named for Claudia J. Alexander, a U.S. Rosetta project scientist. Alexander passed away on July 11, 2015, after a 10-year battle with breast cancer. She was 56.

Alexander earned a bachelor's degree in geophysics from the University of California, Berkeley, and a master's degree in geophysics and space physics from the University of California, Los Angeles. She went on to earn her doctorate degree in atmospheric, oceanic and space sciences from the University of Michigan, Ann Arbor. She began working at NASA's Jet Propulsion Laboratory in California before completing her doctorate. At the relatively young age of 40, she served as project manager for NASA's Galileo mission in 2000.

Alexander strove to inspire young people, writing children's books on science and mentoring young African-American girls. She also wrote "steampunk" science-fiction short stories. [2]

A Taste of Armageddon...

Scene from "A Taste of Armageddon" - I see where SNL got the Cone Heads.

Topics: Commentary, Existentialism, Politics, Star Trek

From "A Taste of Armageddon," Teaser and excerpt of Act I:

On a diplomatic mission, the crew visit a planet that is waging a destructive war fought solely by computer simulation, but the casualties, including the crew of the USS Enterprise, are supposed to be real.

Anan reveals that Eminiar has been fighting a war with the third planet of the system, Vendikar, for almost 500 years. But despite a hit, right in the city, Kirk and his landing party can find no evidence of war. No explosions, no radiation, nothing that would suggest the damage he is assured is occurring.

Spock finally deduces the truth: the war is fought with computers. Casualties are calculated, and the victims have twenty-four hours to report to a disintegration station so their deaths may be recorded. This tidy solution preserves the civilization, despite the cost in lives. Kirk is incredulous that people would simply walk into disintegration machines and never come out; Anan assures him that his people have a high sense of duty. And then Anan tells Kirk that when the Enterprise entered orbit, it became a legitimate target, and it has been destroyed by a tricobalt satellite explosion. Like the victims on the surface, Kirk's crew has twenty-four hours to report for disintegration. Kirk and his party are imprisoned to ensure compliance.

Franklin Delano Roosevelt: "Yesterday, December 7th, 1941 -- a date which will live in infamy -- the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan." Good Reads

George W. Bush: "Good evening. Today our fellow citizens, our way of life, our very freedom came under attack in a series of deliberate and deadly terrorist acts. The victims were in airplanes or in their offices: secretaries, business men and women, military and Federal workers, moms and dads, friends and neighbors. Thousands of lives were suddenly ended by evil, despicable acts of terror." The American Presidency Project

S-hole president*: “He said he didn’t meddle — I asked him again,” Mr. Trump told reporters traveling with him aboard Air Force One as he flew to Hanoi for more meetings. “You can only ask so many times. I just asked him again. He said he absolutely did not meddle in our election. He did not do what they are saying he did.” NY Times

That has been proven a lie in a sequence of colossal, Olympic-level lies with the thirteen indictments last Friday and the thirty-two additional yesterday. It is not a lie; not a hoax. It is the deluge of 2,000 plus lies that have pummeled us; stymied ethics specialists and statisticians tabulating political fact from fiction, alike from our faux chief executive* that has insulted "truth, justice the American way" and everyone BUT Vlad the Impaler of democratic republics.

We

were

ATTACKED!

It didn't result in deaths or casualties, at least not immediately. It didn't result in 3,000+ souls lost and twin towers crashing. It didn't result in the heart wrenching sight of people who decided between fires hot enough to turn human bodies into ash...and gravity as they fell to their certain deaths. Our deaths now are serial: to which we will naval-gaze and pontificate until we grow numb...until the next shooting.

No...what we're witnessing is the death of democracy. It's happening with every school shooting the NRA uses the silent treatment for us to forget (and likely channeled money to a certain campaign from Russian oligarchs). The colossal gun deaths that make it 25 times more likely to die of gun violence in the US only benefits our enemies. We slowly lose hope in the collective responsibility of governance with every march after every shooting, every call to our so-called representatives* that only answer to the whisper of bills from the gun lobby. It doesn't matter to the Russians who they choose for public office. A Florida mayor (a democrat) was indicted for laundering money from Russian benefactors. They could select a democrat in 2020. Holy HELL would break out on the right, and we'd officially have to admit we have no clear way to choose our own leaders without the interference of a hostile foreign power, that are NOT our friends! We'd question every result from city, county, state and national. We could see a Civil War in the 21st Century on American soil that would make dystopian science fiction writers blush. The educated, upper middle class, skilled and well-to-do would depart for Canada, Europe and parts unknown. Universities would lose talented professors that frankly don't want to deal with a country that produces violent citizens - they want to return home to their families too. Innovation would naturally start migrating overseas. The economy would limp along until it collapsed and the world market switches like lightning from the dollar to the Euro as the foundation of world currency. We'd be John Donne's island; isolated by our own hubris, prejudices and shortsightedness. The rest of us, still here would be left in a cesspool formerly known as the "United States" (a historical byword and oxymoron) with a Cheetos puppet emperor in a bad toupee, that's WAY beyond the normal narcissism of the presidency: it's obvious he wants to be worshiped, like a god. Some places online, he is called that.

Armageddon - even a taste of it - may not be with a flash, "but a whimper*."

I've quoted T.S. Elliot before. It's still apropos:

I

We are the hollow men

We are the stuffed men

Leaning together

Headpiece filled with straw. Alas!

Our dried voices, when

We whisper together

Are quiet and meaningless

As wind in dry grass

Or rats' feet over broken glass

In our dry cellar

Shape without form, shade without colour,

Paralysed force, gesture without motion;

Those who have crossed

With direct eyes, to death's other Kingdom

Remember us-if at all-not as lost

Violent souls, but only

As the hollow men

The stuffed men.

III

This is the dead land

This is cactus land

Here the stone images

Are raised, here they receive

The supplication of a dead man's hand

Under the twinkle of a fading star.

Is it like this

In death's other kingdom

Waking alone

At the hour when we are

Trembling with tenderness

Lips that would kiss

Form prayers to broken stone.

(Elliot's last, most quoted stanza)

V

This is the way the world ends

Not with a bang but a whimper*.

Laser Phone Charging...

We've cut the cord for communication, thanks to Bluetooth and Wi-Fi, but charging our little pocket supercomputers still takes a tether. Judging by the range of wireless charging technologies in the works, that might not be the case for much longer. A team from the University of Washington has demonstrated how lasers could be used to charge a device from across the room.

The team mounted a power cell on the back of a smartphone and hit it with a narrow laser beam in the near-infrared part of the spectrum. From a distance of 4.3 m (14 ft), the laser was able to deliver 2 W of power to a 97-sq cm (15-sq in) area, charging the phone about as quickly as a regular old USB cable.

The laser emitter is designed to automatically sense when a phone is ready to be charged, while the smartphone was programmed to send out high-frequency "chirps" inaudible to the human ear that tells the emitter where it is.

"This acoustic localization system ensures that the emitter can detect when a user has set the smartphone on the charging surface, which can be an ordinary location like a table across the room," says Vikram Iyer, co-author on a study describing the device.

RESEARCH

Current Projects:

* African Astronomy & Culture

* Celestial Navigation in Three Cultures: Fiji, Tunisia, and the United States

* Celestial Navigation in East Africa

* Celestial Aspects of African Art

Research Interests: The night sky continues to fascinate people all over the world. How people think about the sky, use the sky, and depict the sky is immensely varied. Assuming that these variations reflect social and environmental differences, I use sky lore and sky knowledge as a way to probe cultures other than my own. Oftentimes, I decipher the science behind the myths: For example, moon goddess myths often speak of the goddess growing larger and then shrinking and growing larger again. This reflects the observed waxing and waning of the moon which occurs over 29.5 days.

As an applied anthropologist, I am thinking through ways in which my research can be of benefit. As a BARA member, I study indigenous knowledge systems and practices primarily to uncover the science in order to better understand the limitations of their effectiveness. This can be important in 'development' settings because quaint practices are then scientifically validated and transformed into practices that work. These practices then can be left intact or modified rather than destroyed.

A 45-year-old telescope is going to get a high-tech upgrade that will enable it to search for answers to the most perplexing questions in astronomy, including the existence of dark energy, a hypothetical invisible force that might be driving the expansion of the universe.

The Nicholas U. Mayall Telescope in Arizona closed earlier this week to prepare for the installation of a 9-ton device that will feature 5,000 pencil-size robots aiming fiber-optic sensors at distant galaxies.

Every 20 minutes, the swiveling robots will reposition to allow the instrument — called the Dark Energy Spectroscopic Instrument (DESI) — to capture a new portion of the sky. Ten extremely powerful instruments called spectrographs will then analyze the light from the distant objects captured by the sensors and create what has been described as the largest and most detailed 3D map of the universe to date.

"We started with a conceptual design for the instrument in 2010," Joseph Silber, a DESI project engineer who works at the University of California's Lawrence Berkeley Laboratory, said in a statement. "It's based on science that was done on the Baryon Oscillation Spectroscopic Survey (BOSS) instrument. But it's all done robotically instead of manually."

Topics: African Americans, Civil Rights, Diaspora, Diversity, Diversity in Science, History, Women in Science

This is Alice Ball, the pharmaceutical chemist who in 1919 developed a medical treatment for Leprosy and gave hope to millions. Her drug was the premier treatment for Leprosy until the 1940’s when antibiotics were developed. Before Alice, Leprosy was considered a hopeless disease. In the US people found to have Leprosy were forcibly removed from their homes and detained indefinitely in remote colonies. Alice’s treatment allowed hundreds of detainees to at last be paroled from the detention centres and go home to their families.

Born in 1892, Alice is the granddaughter of Iconic photographer JP Ball. She graduated from the University of Washington and the University of Hawaii with degrees in pharmacy and pharmaceutical chemistry. Her master’s thesis was titled The Chemical Constituents of Piper Methysticum and involved extracting active ingredients from kava root. Her chemistry work here was so impressive that she was enlisted by US Public Health Officer Dr Harry Hollmann to work her magic with chaulmoogra oil.

For centuries, Indian and Chinese health practitioners have been using chaulmoogra oil to treat leprosy but with limited success. The oil could be applied topically however that would mean it wouldn’t penetrate deep enough into the body; at best, it provided sufferers with some relief. Oil is not soluble in water therefore injecting was extremely difficult near impossible. Patients described the oil injections as ‘burning like fire through the skin’.

This is where Alice comes in. She was enlisted to use her unique skills and techniques to extract the active ingredients from chaulmoogra oil. She isolated the chaulmoogric acid and hydnocarpic acid contained in the oil and created the first water soluble injectable treatment for leprosy. At aged 24 she had managed to do something that had “thwarted researchers for years”.

It is my observation we haven't quite mastered terrestrial encounters with other hominids of differing cultures or shades of Melanin. So, an actual encounter with extraterrestrial life would be at this moment in our existence daunting. We're not ready, for extraterrestrials, or very frequently, each other.

When ‘Oumuamua, a mysterious interstellar object, swept through our solar system last October, it elicited breathless news stories all asking the obvious question—is it a spaceship? There were no signs it was—although many people seemed to hope otherwise.

Throughout history most strange new cosmic phenomena have made us wonder: Could this be it, the moment we first face alien life? The expectation isn’t necessarily outlandish—many scientists can and do make elaborate, evidence-based arguments that we will eventually discover life beyond the bounds of our planet. To true believers, what may be more uncertain is whether or not such news would cause global panic—which depends on how our minds, so greatly influenced by our Earthly environment and society, would perceive the potential threat of something utterly outside our familiar context.

If it’s a discovery somewhere in between the extremes of an extraterrestrial microbe and rapacious, hostile aliens laying siege to Earth, will people respond differently based on the era or society they live in?

Our brains are wired with ancient circuits to defend us against predators. But as we navigate through the world, experience can also shape what we come to accept or to fear and how open we are to novelty. This study only looked at U.S. responses but two neuroscientists think the results might have been very different around the world. “If you look at societies that are much less open and much more xenophobic and so on, they might perceive [finding extraterrestrial life] as much more negative and unsettling,” says Israel Liberzon, a professor of psychiatry, psychology and neuroscience at the University of Michigan who was not part of the study.

“Culture may be a strong determinant of how we respond to novelty,” says Cornelius Gross, a neuroscientist at the European Molecular Biology Laboratory–Rome who studies the neural circuitry of fear and was also not involved with the research. “People came to America because they were novelty seekers, so we’ve selected for [that] and then continued to foster novelty seeking and place it very high on our list.” Furthermore, Shostak says, a person’s religious beliefs could play a powerful role in shaping their reaction to learning that humanity is in fact not as universally special as many traditions hold.

Slavery and the American University...

Without modification, the title is the name of a book in the NY Review of Books. Apropos, considering the times we live in.

It's interesting that my Alma Mater was birthed in 1891, some 27 years after the end of the Civil War. It has established itself as a primary source of STEM graduates, and still graduates more African American engineers than any other institution.

Others, some noteworthy have a more sullen history. It is thus understandable, that the institution of white supremacy had in its underpinnings self-regulated "justifications" from clergy and academia. It makes a "self-evident truth" that white culture has clung to as its only solace in an unfair system even to themselves. It is a faux orthodoxy that has prepared us for this unique moment of authoritarian fascism.

We were in Tennessee (Bill Moyers as a young staffer with President Lyndon B. Johnson). During the motorcade, he spotted some ugly racial epithets scrawled on signs. Late that night in the hotel, when the local dignitaries had finished the last bottles of bourbon and branch water and departed, he started talking about those signs. “I’ll tell you what’s at the bottom of it,” he said. “If you can convince the lowest white man he’s better than the best colored man, he won’t notice you’re picking his pocket. Hell, give him somebody to look down on, and he’ll empty his pockets for you.” Source: Snopes - LBJ: convince the lowest white man quote

According to the surviving records, the first enslaved African in Massachusetts was the property of the schoolmaster of Harvard. Yale funded its first graduate-level courses and its first scholarship with the rents from a small slave plantation it owned in Rhode Island (the estate, in a stroke of historical irony, was named Whitehall). The scholarship’s first recipient went on to found Dartmouth, and a later grantee co-founded the College of New Jersey, known today as Princeton. Georgetown’s founders, prohibited by the rules of their faith from charging students tuition, planned to underwrite school operations in large part with slave sales and plantation profits, to which there was apparently no ecclesiastical objection. Columbia, when it was still King’s College, subsidized slave traders with below-market loans. Before she gained fame as a preacher and abolitionist, Sojourner Truth was owned by the family of Rutgers’s first president.

From their very beginnings, the American university and American slavery have been intertwined, but only recently are we beginning to understand how deeply. In part, this can be attributed to an expansion of political will. Barely two decades ago, questions raised by a group of scholars and activists about Brown University’s historic connection to slavery were met with what its then-president, Ruth Simmons, saw as insufficient answers, and so she appointed the first major university investigation. Not long before that, one of the earliest scholars to independently look into his university’s ties to slavery, a law professor at the University of Alabama, began digging through the archives in part to dispel a local myth, he wrote, that “blacks were not present on the campus” before 1963, when “Vivian Malone and James Hood enrolled with the help of Nicholas Katzenbach and the National Guard.” He found, instead, that they preceded its earliest students, and one of the university’s first acts was the purchase of an enslaved man named Ben. In Virginia, a small consortium founded three years ago to share findings and methods has expanded to include nearly three dozen colleges and universities across North America and two in European port cities. Almost all of these projects trace their origins to protests or undergraduate classes, where a generation of students, faculty, archivists, activists, and librarians created forums for articulating their questions, and for finding one another.

Topics: Astronomy, Astrophysics, Exoplanets

Discoveries of exoplanets in our galaxy exceed 3,700 to date, but if that’s not enough for you, astronomers are now probing outside of the Milky Way to find exoplanets in other galaxies. A group of researchers at the University of Oklahoma has just announced the discovery of a large population of free-floating planets in a galaxy 3.8 billion light-years away. Their results were published February 2 in the Astrophysical Journal Letters.

The researchers used a method known as quasar microlensing, which has traditionally been used to study the disk-like regions around supermassive black holes where material gathers as it spirals in toward the event horizon. When a distant quasar is eclipsed by a closer galaxy, the intervening galaxy will create several magnified replica images of the quasar. These replicas are further magnified by stars in the interloping galaxy to create a final super-magnified image that can be used to study the quasar in detail.

The cultural reference: James Meredith shot after staging a "long walk" (his solo March Against Fear) from Memphis, Tennessee to Jacksonville, Mississippi encouraging voter registration for African Americans in the south.

I was proudly part of the online record-breaking purchase on Fandango. I started a Facebook group for the movie. Sadly, there are groups formed to boycott it, by people of color uncomfortable with the idea the Black Panther, like Pharaoh in ancient Egypt would be considered a god. There will be the sad/mad/pound puppies that foam at the mouth and howl at the moon at any speculative fiction that doesn't look like a spliced clone of James T. Kirk and Han Solo. They're the same group of spoiled narcissists that had something to say about Voyager's Captain Janeway; Deep Space 9's Commander, then Captain Benjamin Sisko and Michael Berman on Discovery. It's old, it's long and tiresome. But this is a movie I've been waiting for my entire life. Black Panther came out when I was barely out on the planet in 1966 - I was four years old. I am 55 now.

“Wakanda is a small country in Africa notable for never having been conquered in its entire history. When you consider the history of the region, the fact that the French, the English, the Belgians or any number of Christian or Islamic invaders were never able to defeat them in battle…well it’s unprecedented.” The Black Panther - Marvel Knights DVD limited series.

I don't have a vivid memory of Medgar Evers or Malcolm X - just what people told me, what I read and documentaries or dramas that I've viewed.

I do have a vivid memory of the life and death of Martin Luther King, Jr. I recall he was a Trekkie and talked Nichelle Nicholes out of quitting the show. I have a memory of Nichelle Nicholes and William Shatner sharing the first interracial kiss on Plato's Stepchildren, and how like in many markets in the south it was blocked in North Carolina (I wouldn't see it until I was an adult when it went into syndication reruns). I have a memory of the hot tears of five-year-olds in a segregated kindergarten that felt like we'd lost our favorite grandfather or uncle at the news he was no more from teachers that shared our grief. I have a vivid recollection of Confederate flags that paraded on pickup trucks in East Winston-Salem, NC... in celebration of Dr. King's assassination. For those of us in my age group, we resolved to not make his death in vein. If he would look upon our lives, we were determined to make him proud.

I recall the tears my wife shed on the election of the country's first African American president and the memory of her grandparents. Her grandfather "Paw-Paw" almost died in Shreveport, Louisiana at the hands of two white Klansmen for ATTEMPTING to vote. Serendipitously, it was two other white males that sped him to the hospital and saved his life. He, nor his bride "Mother Dear" lived to see the fruition of their labors in the personification of the country's first black president. The republic had existed 232 years, and with the exception of changing parties, managed to keep the office of Chief Executive distinctly white and (so far) exclusively male. Barack Obama was the seventh candidate we had all seen. Running for president as a black candidate was a running joke: you could run, you just couldn't WIN. The death threats and secret service protection he needed as a candidate said something was different this time.

The white backlash was immediate, as if a membrane had been jostled on a sensitized nerve. The rumble started with birtherism, "praying for the president" (reference Psalm 109:8-10); witch doctor effigies during the debates on affordable healthcare (that in hindsight benefited the complainers); screaming citizens at the border in the direction of brown children (the mortar for mythical border walls); and a beautiful, bright and loving African American family - the personification of the Huxtables before the downfall of Bill Cosby - routinely compared to animals and gorillas by people who haven't looked in the mirror, lately.

So, it is in this juxtaposition of previous, audacious hope; the resurgence of overt, de facto nationalistic, white supremacy racism, and a future in the hands of rank incompetents and xenophobes that we look forward to this movie. I don't know what will occur in the aftermath. I can only hope for a good, UPLIFTING and entertaining film.

The photo above says everything we've endured in our long walk. We'll do so as always, going forward in dashikis and "straight outta Wakanda" t-shirts with our backs rod straight. I'd like to think - like Star Trek - Dr. King would have loved it.

"Change does not roll in on the wheels of inevitability, but comes through continuous struggle. And so we must straighten our backs and work for our freedom. A man can't ride you unless your back is bent." Martin Luther King, Jr.

The sobering part is, Europe will likely build a quantum Internet before us, China will commercialize clean energy; everywhere else will have MAGLEV (magnetic levitation) bullet trains that go 200 mph (while we're stuck with the ones that fatally crash at 80), our bridges, railroads and general infrastructure crumbling (toll road taxed to death) from a malignant narcissist, political amateur conman's claim of being "great again."

Before she became a theoretical physicist, Stephanie Wehner was a hacker. Like most people in that arena, she taught herself from an early age. At 15, she spent her savings on her first dial-up modem, to use at her parents’ home in Würzburg, Germany. And by 20, she had gained enough street cred to land a job in Amsterdam, at a Dutch Internet provider started by fellow hackers.

A few years later, while working as a network-security specialist, Wehner went to university. There, she learnt that quantum mechanics offers something that today’s networks are sorely lacking — the potential for unhackable communications. Now she is turning her old obsession towards a new aspiration. She wants to reinvent the Internet.

The ability of quantum particles to live in undefined states — like Schrödinger’s proverbial cat, both alive and dead — has been used for years to enhance data encryption. But Wehner, now at Delft University of Technology in the Netherlands, and other researchers argue that they could use quantum mechanics to do much more, by harnessing nature’s uncanny ability to link, or entangle, distant objects, and teleporting information between them. At first, it all sounded very theoretical, Wehner says. Now, “one has the hope of realizing it”.

Afrofuturism: The World of Black Sci-Fi and Fantasy Culture By YTASHA L. WOMACK

In this hip, accessible primer to the music, literature, and art of Afrofuturism, author Ytasha Womack introduces readers to the burgeoning community of artists creating Afrofuturist works, the innovators from the past, and the wide range of subjects they explore. From the sci-fi literature of Samuel Delany, Octavia Butler, and N. K. Jemisin to the musical cosmos of Sun Ra, George Clinton, and the Black Eyed Peas’ will.i.am, to the visual and multimedia artists inspired by African Dogon myths and Egyptian deities, the book’s topics range from the “alien” experience of blacks in America to the “wake up” cry that peppers sci-fi literature, sermons, and activism. With a twofold aim to entertain and enlighten, Afrofuturists strive to break down racial, ethnic, and social limitations to empower and free individuals to be themselves.

An article that appears on io9.com by Jess Nevins, 9/27/12. I include a link below to a remarkable, mentioned and available book "Light Ahead for the Negro," by Edward A. Johnson

Africans, and those of African descent, have not been treated well by speculative fiction, both inside its texts and in real life. Anti-African racism is a fact of life in Western culture, and was even more pronounced before 1945. Not surprisingly, the number of works of speculative fiction written by black writers is low. But that number is not zero, and it's worth taking a look at the fantasy and science fiction stories that black writers produced before 1945.
