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.

Wattpad Journey

Posted by Leah Ashton on March 8, 2018 at 9:53pm

I have been on a site called Wattpad for almost a year now. I like that this website is for undiscovered writers.

I currently have four stories on here. One has a ghost in it, two have Mermaids and one also includes werewolves and witches.

 I feel a little odd writing about witches, as I have never seen any African American Wiccans or witches for that matter. I guess they are out there just like the rest of the supernaturals. I keep running into brief spells of writers block and then suddenly I get an idea.

I have been trying to learn how to finish my ideas instead of stopping and starting again. My main thing with Wattpad is that while I have about 17 followers, only two commented. I use the feedback I get to revise my stories, if I don't get anything then I end up unpublishing the story.

Aside from that I enjoy it. My daughter is a writer on there too.

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."

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.

A Taste of Armageddon...

Posted by Reginald L. Goodwin on February 23, 2018 at 9:31am
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

This is the way the world ends

This is the way the world ends

Not with a bang but a whimper*.

Dr. Claudia Alexander, In Memoriam...

Posted by Reginald L. Goodwin on February 23, 2018 at 9:35am
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 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."

We have come so far by faith

Posted by Ms. Regina Owens on February 20, 2018 at 7:24pm

Let us not forget those who have gone before us, who have fought the good fight with faith, and courage. Black History Month is due in remembrance of them all, and us today must not allow those torches of courage to ever go out. Kudos to the Black Panther movie, now a superhero movie for us--not one of a "pale like," one that bolts out of a phone booth wearing a flying like red and blue cape. Blessings to you all!

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.

Ready for S.E.T.I...

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.

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”.

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.

"The Day We Surrender to the Air" by Antonio Jose Guzman
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.

To Be, or Not to Be...

Cultural reference: Hamlet, Act III, scene I.

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”.

Atomically Precise Manufacturing...

A University of Texas at Dallas graduate student, his advisor and industry collaborators believe they have addressed a long-standing problem troubling scientists and engineers for more than 35 years: How to prevent the tip of a scanning tunneling microscope from crashing into the surface of a material during imaging or lithography.

Details of the group's solution appeared in the January issue of the journal Review of Scientific Instruments, which is published by the American Institute of Physics.

Scanning tunneling microscopes (STMs) operate in an ultra-high vacuum, bringing a fine-tipped probe with a single atom at its apex very close to the surface of a sample. When voltage is applied to the surface, electrons can jump or tunnel across the gap between the tip and sample.

"Think of it as a needle that is very sharp, atomically sharp," said Farid Tajaddodianfar, a mechanical engineering graduate student in the Erik Jonsson School of Engineering and Computer Science. "The microscope is like a robotic arm, able to reach atoms on the sample surface and manipulate them."

The problem is, sometimes the tungsten tip crashes into the sample. If it physically touches the sample surface, it may inadvertently rearrange the atoms or create a "crater," which could damage the sample. Such a "tip crash" often forces operators to replace the tip many times, forfeiting valuable time.

Dr. John Randall is an adjunct professor at UT Dallas and president of Zyvex Labs, a Richardson, Texas-based nanotechnology company specializing in developing tools and products that fabricate structures atom by atom. Zyvex reached out to Dr. Reza Moheimani, a professor of mechanical engineering, to help address STMs' tip crash problem. Moheimani's endowed chair was a gift from Zyvex founder James Von Ehr MS'81, who was honored as a distinguished UTD alumnus in 2004.

"What they're trying to do is help bring atomically precise manufacturing into reality," said Randall, who co-authored the article with Tajaddodianfar, Moheimani and Zyvex Labs' James Owens. "This is considered the future of nanotechnology, and it is extremely important work."
