Originally posted as "The Meaning..." #P4TC, July 5, 2015.
Today is Valentine's Day and Frederick Douglass's 200th birthday, or at least the day he assigned for himself. One of my favorite quotes by him (that I use) is "The soul that is within me, no man can degrade."
Frederick Douglass was known well for being an escaped slave, committed republican (at that time in our history, the progressive party) and abolitionist. He was a staunch advocate of equality (an early one for women) and education, seeing his own personal emancipation centered on something slaves were banned from doing: reading. His former master chastised his wife, saying teaching Frederick how to read would "ruin him" and make him unfit for the peculiar institution. He couldn't have agreed more.
In his uniquely bellicose manner, Mr. Douglass tackles this in a long soliloquy given July 5, 1852 in Rochester, NY. I have thought of Charleston, South Carolina and how the narrative of our nation had been determined by a defeated foe to the point of redefining the narrative and main rationale (if you can call it that) behind the Civil War: the continued indentured servitude of a kidnapped people in perpetuity. In light of the debate sparked by the assassination of nine innocents in Mother Emanuel AME, and the symbol the terrorist so revered; the possibility on that symbol's removal in the bloody aftermath, I give you Frederick Douglass' apropos speech on its 163rd anniversary in excerpt, read by the accomplished actor and voice of Darth Vader, James Earl Jones.
Mr. President, Friends and Fellow Citizens:He who could address this audience without a quailing sensation, has stronger nerves than I have. I do not remember ever to have appeared as a speaker before any assembly more shrinkingly, nor with greater distrust of my ability, than I do this day. A feeling has crept over me quite unfavorable to the exercise of my limited powers of speech. The task before me is one which requires much previous thought and study for its proper performance. I know that apologies of this sort are generally considered flat and unmeaning. I trust, however, that mine will not be so considered. Should I seem at ease, my appearance would much misrepresent me. The little experience I have had in addressing public meetings, in country school houses, avails me nothing on the present occasion.The papers and placards say that I am to deliver a Fourth of July Oration. This certainly sounds large, and out of the common way, for me. It is true that I have often had the privilege to speak in this beautiful Hall, and to address many who now honor me with their presence. But neither their familiar faces, nor the perfect gage I think I have of Corinthian Hall seems to free me from embarrassment.The fact is, ladies and gentlemen, the distance between this platform and the slave plantation, from which I escaped, is considerable-and the difficulties to he overcome in getting from the latter to the former are by no means slight. That I am here to-day is, to me, a matter of astonishment as well as of gratitude. You will not, therefore, be surprised, if in what I have to say I evince no elaborate preparation, nor grace my speech with any high sounding exordium. With little experience and with less learning, I have been able to throw my thoughts hastily and imperfectly together; and trusting to your patient and generous indulgence I will proceed to lay them before you.This, for the purpose of this celebration, is the Fourth of July. It is the birth day of your National Independence, and of your political freedom. This, to you, as what the Passover was to the emancipated people of God. It carries your minds back to the day, and to the act of your great deliverance; and to the signs, and to the wonders, associated with that act, and that day. This celebration also marks the beginning of another year of your national life; and reminds you that the Republic of America is now 76 years old. l am glad, fellow-citizens, that your nation is so young. Seventy-six years, though a good old age for a man, is but a mere speck in the life of a nation. Three score years and ten is the allotted time for individual men; but nations number their years by thousands. According to this fact, you are, even now, only in the beginning of your national career, still lingering in the period of childhood. I repeat, I am glad this is so. There is hope in the thought, and hope is much needed, under the dark clouds which lower above the horizon. The eye of the reformer is met with angry flashes, portending disastrous times; but his heart may well beat lighter at the thought that America is young, and that she is still in the impressible stage of her existence. May he not hope that high lessons of wisdom, of justice and of truth, will yet give direction to her destiny? Were the nation older, the patriot's heart might be sadder, and the reformer's brow heavier. Its future might be shrouded in gloom, and the hope of its prophets go out in sorrow. There is consolation in the thought that America is young.-Great streams are not easily turned from channels, worn deep in the course of ages. They may sometimes rise in quiet and stately majesty, and inundate the land, refreshing and fertilizing the earth with their mysterious properties. They may also rise in wrath and fury, and bear away, on their angry waves, the accumulated wealth of years of toil and hardship. They, however, gradually flow back to the same old channel, and flow on as serenely as ever. But, while the river may not be turned aside, it may dry up, and leave nothing behind but the withered branch, and the unsightly rock, to howl in the abyss-sweeping wind, the sad tale of departed glory. As with rivers so with nations.

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."

The scholarship gala for the Greensboro Medical Society used as its theme Egypt, specifically Imhotep, the original father of medicine, despite Hippocrates holding that distinction in the west. The presentation was to honor Dr. Otis E. Tillman, Sr., who delivered babies at then segregated hospitals in High Point, Greensboro and Winston-Salem. It was with chills that I had an epiphany: this gentle giant of medicine, who had himself endured many indignities of racism and segregation, may have delivered me at Kate Bitting Reynolds Hospital. It was possible. I didn't ask, but it did send chills to hear his clear enunciation, mental acuity and stirring story. I also met my new dentist, who I'll likely be under his care as of this posting. It was a wondrous evening.
The Greensboro Medical Society (GMS) was formed several years after the opening of L. Richardson Memorial Hospital which opened on May 4, 1927. Early accounts indicate that the society was not active during the late 1920's and 1930's. In the mid 1940's; however, the GMS was re-activated. During this time, Drs. G.H. Evans, C.C. Stewart, J.P. Sebastian, J.C. Waddy, J.R. Hawkins, W.J. Hughes, Sr., G.C. Simkins, Sr., B.W. Barnes, M.S. Jenkins, W. Murrow, and Hargraves were the physicians, dentists and pharmacists who composed the Society and staffed L. Richardson Hospital. All members were also affiliated with the Old North State Society and National Medical Association. They came together during this time for the purpose of education, fellowship, networking and socialization.
Because of the policy of segregation, which was prevalent in America during this time, these doctors were denied staff privileges at the majority hospitals and membership in the mainstream majority health professional organizations. These included the American Medical Association, American Dental Association and their regional and local affiliates. The Greensboro Medical Society therefore served as an outlet to temper the ill-effects of the isolation of these times.
After World War II, leaders in the black community were determined to improve health care for black persons by ending discrimination in hospital policies and practices. Leaders of professional organizations developed a collaborative strategy that involved the court system, federal legislation, and research and education of the public and health professionals to integrate the hospital system rather than to expand the existing separate-but-equal system. Efforts culminated in the case of Simkins v Moses H. Cone Memorial Hospital; this case became the landmark decision by the U.S. Supreme Court and led to the elimination of segregated health care.

| Imhotep, The Encyclopedia Britannica online |
Topics: Africa, Diaspora, Diversity, Diversity in Science
Alternative Title: Imouthes
Imhotep, Greek Imouthes, (born 27th century BCE, Memphis, Egypt), vizier, sage, architect, astrologer, and chief minister to Djoser (reigned 2630–2611 BCE), the second king of Egypt’s third dynasty, who was later worshiped as the god of medicine in Egypt and in Greece, where he was identified with the Greek god of medicine, Asclepius. He is considered to have been the architect of the step pyramid built at the necropolis of Ṣaqqārah in the city of Memphis. The oldest extant monument of hewn stone known to the world, the pyramid consists of six steps and attains a height of 200 feet (61 metres).
 |
| Step pyramid, Ṣaqqārah necropolis, Memphis, Encyclopedia Britannica |
Imhotep’s high standing in Djoser’s court is affirmed by an inscription bearing his name on a statue of Djoser found at the site of the Ṣaqqārah pyramid. The inscription lists a variety of titles, including chief of the sculptors and chief of the seers. Although no contemporary account has been found that refers to Imhotep as a practicing physician, ancient documents illustrating Egyptian society and medicine during the Old Kingdom (c. 2575– c. 2130 BCE) show that the chief magician of the pharaoh’s court also frequently served as the nation’s chief physician. Imhotep’s reputation as the reigning genius of the time, his position in the court, his training as a scribe, and his becoming known as a medical demigod only 100 years after his death are strong indications that he must have been a physician of considerable skill.

The Biomedical Engineer
Treena Livingston Arinzeh, Ph. D.
Associate Professor
New Jersey Institute of Technology
Armed with a master’s in biomedical engineering from Johns Hopkins University and a Ph.D. in bioengineering from the University of Pennsylvania, Treena Livingston Arinzeh was the first to demonstrate, in 2003, that scientists can implant donor stem cells derived from the bone marrow of adults to form functional, viable bone tissue that is not rejected by the body.
Replacing bone tissue using donor stem cells has far-reaching applications. For one, patients may not need to undergo immunosuppression therapy, which can cause infection, osteoporosis, and damage to the kidney, liver, or pancreas. In addition, her research has led to clinical methods to induce bone repair of diabetics and others who have bone injuries. As a result of her findings, in 2004 President George W. Bush presented her with the Presidential Early Career Award for Scientists and Engineers, the nation’s highest scientific honor. Her research is now mimicked in bone marrow transplant procedures across the country.
Arinzeh, now an associate professor of biomedical engineering at the New Jersey Institute of Technology, says that women make up 50% of undergraduates in biomedical engineering but that there aren’t enough African Americans pursuing careers in her area. She says students must be engaged by mentors, and parents need to get them involved in extracurricular activities. “I think they don’t see enough of us that look like them so they can identify with that career as something they can actually do,†says Arinzeh, who invites 40 to 50 underrepresented high school students to her lab each summer, through the Project Seeds program, sponsored by the American Chemical Society.

A novel model developed at the U.S. Department of Energy’s (DOE) Argonne National Laboratory allows industry, the Department and others to gauge the impact of recycling batteries in electric vehicles. It could further energize this market.
“Argonne has a long track record of expertise in battery research and development, and now we have added the ability to examine every step along the way, from manufacturing to recycling,” said Argonne’s Jeff Spangenberger, the project leader.
From cathodes to anodes and electrolytes, Argonne’s understanding of batteries, combined with ReCell, a closed-loop battery recycling model, offers preliminary estimates of total costs as well as environmental impacts such as carbon dioxide emissions. The model breaks down each process from when a battery leaves the factory to when it is recycled.
Argonne’s ReCell model can provide information to manufacturers up front, so those manufacturers can determine life cycle costs with precision and provide batteries to consumers with minimal environmental and economic impacts. Argonne’s researchers have designed ReCell to be versatile and adapt to the challenges that recycling of lithium ion batteries present, such as differing battery chemistries and formats.

July 27, 2009, Wikipedia:
Orly Taitz+ (born August 30, 1960)[8] is a Moldovan-American political conspiracy theorist. A dentist, lawyer,[9] and former real estate agent,[10][11] Taitz was a figure in the "birther" movement, which promoted the conspiracy theory that Barack Obama was not a natural-born citizen eligible to serve as President of the United States. Taitz also promotes a number of other conspiracy theories both related and unrelated to Obama. Taitz has initiated a number of lawsuits on behalf of the "birther" movement; all were dismissed by the courts, and on one occasion Taitz was ordered to pay $20,000 as a sanction for misconduct in filing frivolous claims. Taitz has unsuccessfully run for statewide office in California three times.
Taitz alleges that President Obama is not a natural-born citizen of the United States and is therefore ineligible to serve as President. She claims he was born in Kenya and that he falsified his Selective Service papers and his application to the Illinois bar.[22] "I believe [Obama] is the most dangerous thing one can imagine, in that he represents radical communism and radical Islam: He was born and raised in radical Islam, all of his associations are with radical Islam, and he was groomed in the environment of the dirty Chicago mafia. Can there be anything scarier than that?" [1]
April 4, 2011, Politico:
Birtherism is the latest and most enduring version of a theory in search of facts.
The original smear against Obama was that he was a crypto-Muslim, floated in 2004 by perennial Illinois political candidate and serial litigant Andy Martin. Other related versions of this theory alleged that Obama was educated in an Indonesian “madrassa” or steeped in Islamist ideology from a young age, and the theories began to spread virally after Obama appeared on the national stage – to the casual observer, from nowhere – with his early 2007 presidential campaign announcement.
All through that year, the Obama campaign – with the affirmation of most leaders of both parties – aggressively battled that smear by emphasizing his Christian faith. Obama’s controversial but emphatically Christian pastor emerged as a campaign issue and the belief that he was a Muslim seemed to lose traction.
Then, as Obama marched toward the presidency, a new suggestion emerged: That he was not eligible to serve.
That theory first emerged in the spring of 2008, as Clinton supporters circulated an anonymous email questioning Obama’s citizenship.
“Barack Obama’s mother was living in Kenya with his Arab-African father late in her pregnancy. She was not allowed to travel by plane then, so Barack Obama was born there and his mother then took him to Hawaii to register his birth,” asserted one chain email that surfaced on the urban legend site Snopes.com in April 2008. [2]
February 14, 2014, Outside the Beltway:
While the American public as a whole has a largely negative view of both Vladmir Putin and Russia as a whole, there is a segment of the American public that has, over the past several years developed an oddly positive opinion of a nation that Mitt Romney, to the cheers of many on the right, called our biggest geopolitical rival, and a man who was once a top agent in the KGB. What’s odd is that these cheers are not coming from the left side of the political aisle as they might have in the 1930s, but from the right. Back in August, I observed that people such as Pat Buchanan and Rod Dreher have been heaping praise on Putin for things such as the anti-gay “propaganda” laws that he push through the Russian legislature and compared him positively to President Obama and what seems to be the new version of Buchanan’s “culture war” argument from the 1992 Presidential campaign. In December, Buchanan and Dreher were back with more praise for the Russian President and his authoritarian, anti-equality, and allegedly “pro-Christian” policies. [3]
October 24, 2016, New Republic:
Public-opinion polling shows that Trump’s low opinion of American elections has practically become Republican Party orthodoxy. According to a Reuters/Ipsos poll released on Friday, Republicans have an “unprecedented” level of “concern and mistrust in the system.” Roughly 70 percent of Republican voters believe that if Hillary Clinton wins the election, it’ll be due to fraud. In both this poll and an NBC News/SurveyMonkey poll, only half of Republicans say they’d accept a Clinton victory. (In the latter poll, by contrast, 82 percent of Democrats said they would accept a Trump victory.)
This suspicious Republican electorate is joined by growing ranks of conservative politicians, pundits, and intellectuals. They’re all increasingly willing to say that the existing American political system is hopelessly flawed and needs to be rolled back to the days before blacks and women could vote. On the most obvious level, this can be seen in moves by Republican governors all over America to make voting more difficult, through stringent voting ID laws, new hurdles to registration, and the curtailment of early-voting options. Equally significant has been the gutting of key provisions of the Voting Rights Act by conservative Supreme Court justices in the 2013 Shelby Country v. Holder ruling.
But these overt forms of voting suppression are merely the most visible manifestations of a larger questioning of democracy on the political right. Trump’s anti-democratic rhetoric—and the eagerness of so many good, white patriotic Americans to cheer it and believe it—is a symptom of the larger trend on the political right toward doubting the legitimacy of the American system. The question we need to be asking isn’t, “Why is Trump being such a jerk?” It’s, “Why is the American Right giving up on democracy?” [4]
One interesting side bar: Orly Taitz+ - the original birther conspiracy theorist before our erstwhile Putin-puppet, Manchurian candidate president* took up the mantle - like two of his three serial marriages is herself an immigrant.
In the 1994 book "Black Labor, White Wealth" by Dr. Claude Anderson, the 1850 census found the slave population coming to parity with the majority white population. Up to that point, "white" had a specificity and excluded certain European countries. Because that parity - even for a slave population - meant an increase in power, the definition of that artificial demarcation got "liberal." To maintain superior numbers, the US opened the floodgates. Czechs, Italians, Jews and Poles would eventually be considered a part of the majority, as if their exclusion had never occurred. It's always been a numbers game.
The immigration policies regarding LEGAL immigration ala Stephen Miller would delay the date white Americans become a numerical minority by five years. It moved from originally 2050 to 2042; it had recently shifted by two years to 2044, apparently. The policies again, on legal immigration thus push it a year before the original 2050 date, which is a deliberate calculus, but it doesn't stop it. The specific targeting of a diverse diaspora is quite deliberate. Couple that with the fever pitched effort to suppress the votes of people of color, you have a naked exercise in white supremacy you can easily measure. It's been the nature of the nation from its genocidal (Native Americans) and kidnapping (African Americans) origins.
It's never been about Christian "family values," if the enabling of wife beaters that don't need security clearances attests to. Christian supremacy - according to the thesis of "The Sin of White Supremacy: Christianity, Racism, and Religious Diversity in America" by Jeannine Hill Fletcher (a white theologian) is the bedrock on which this nation's bigoted behavior was founded on.
And now it has a voice: the personification of its calamitous zeitgeist: a true man of lawlessness. A need to look back to a pristine time of superiority. It clarifies opposition to people of color, deport any and all Hispanic/Latino immigrants (legal or not), label whole nations in the Caribbean and on the African continent s-house countries (as if "hole" was the insult); the LGBT (they biologically cannot make white babies, to paraphrase Steve King's ridiculous statement). It makes the rise of racist organizations - be they alt-right, birther, homophobic, KKK, Neo Nazi - have a consistent, base theme.
That theme is fear.
“Fear is the path to the dark side…fear leads to anger…anger leads to hate...hate leads to suffering.” Yoda, "Star Wars: The Phantom Menace," May 6, 2014

The Mathematician
Tanya Moore, Ph. D.
Youth Services Coordinator, 2020 Vision Projects
City of Berkley California’s Unified School District
Tanya Moore demonstrates that mathematicians can help divert social catastrophes. As the leader of the city-wide 2020 Vision Projects, launched in June 2010, Moore’s job is to help close the achievement gap between white, black, and Latino students in Berkeley, California, by 2020. She has a central role in designing the surveys, methodologies, and statistical indicators to be used for tracking student progress. After analyzing the data, she will help design and evaluate youth interventions and services across community agencies and city departments.
Moore’s concern with increasing educational achievement for minorities doesn’t end in Berkeley, where she received her Ph.D. in biostatistics. She also spearheads Infinite Possibilities, a national conference for women of color in all stages of mathematics–from high school students to post-docs and women in private industry. “I started it initially as a reunion because of the experiences I had at Spelman [College]. Now it has grown. It has created this wonderful community over the last few years.
Participants regularly write Moore about how Infinite Possibilities helped them feel less isolated in grad school. She understands their frustration firsthand. While working on a master’s degree at Johns Hopkins she received her share of intolerant comments. “People told me I would only pass qualifying exams because I was an African American woman and the school wanted to make their quota. I’d walk into a room and people would tell me I was in the wrong classroom. Sometimes a professor would say ‘Wow, you did better than we expected.’"

The title of the post originates from a pejorative. The initials "SJW" are meant as an insult to discourage a post on a topic like police brutality against a group (e.g. Black Lives Matter) as being too "politically correct." What is typically left out of the missive is the considerable amount of courage it takes to actually live the initials.

Citation:
"for her leadership in campaigning for peace, justice, and the abolition of the death penalty and for her unwavering efforts to promote the human rights and freedoms of the Iranian people, despite persecution that has forced her to suspend her scientific pursuits and endure lengthy incarceration."
Background:
Narges Mohammadi, an Iranian physicist, engineer, and human rights defender currently serving a 16-year sentence in Evin Prison (Tehran), was born in Zanjan in 1972. She majored in physics at Imam Khomeini University in Qazvin, where she became actively involved in promoting rights and social justice by founding a political student organization and publishing on issues related to women’s and students’ rights. After graduating, she worked both as an engineer with the Iran Engineering Inspection Corporation and as a journalist, highlighting issues related to gender equality. Ms. Mohammadi’s efforts to maintain a career in the sciences while speaking out about human rights abuses were unsuccessful. In 2009 she was dismissed from her position with the Engineering Inspection Corporation. The same year, she was arrested and incarcerated.
Ms. Mohammadi is known globally for her efforts to promote and protect the rights of women, prisoners of conscience, minority communities, and other vulnerable groups. She has also been deeply involved in efforts to promote free and fair elections and abolish the death penalty in her country. As spokesperson and vice-president of the Defenders of Human Rights Center (DHRC), an organization founded in 2001 by Nobel Peace Laureate Shirin Ebadi and other prominent Iranian lawyers, and closed by the government in 2008, Ms. Mohammadi helped to provide pro bono legal assistance to prisoners of conscience and monitor the human rights situation in Iran. She also served as president of the Executive Committee of the National Council of Peace in Iran, an organization dedicated to opposing military conflict and violence. Together with other human rights activists, she created the Women’s Civil Center, a body that defends the rights of women, political prisoners, and minorities. Her courageous actions in support of human rights have taken many forms, from protests before parliament concerning acid attacks on women to prison vigils with the families of individuals facing execution. Ms. Mohammadi is the recipient of the 2009 international Alexander Langer Award and the 2011 Per Anger Prize for human rights.

The Chemist
Ashanti Johnson, Ph. D.
Chemical Oceanographer/Geochemist
University of South Florida,
College of Marine Science
Studying soil and sedimentation of rivers, estuaries, and beaches, Ashanti Johnson’s work as an aquatic radiogeochemist was instrumental in decoding the environmental effects of potentially hazardous incidents throughout Puerto Rico.
Johnson can be found scouring the beaches of Rincón, where a nuclear power plant operated until the 1970s, or collecting soil samples in Vieques, where depleted uranium residue remained for years following an artillery firing range run by the U.S. Navy. “These problems have been investigated very little," says Johnson. “It takes a lot of dedication and is really labor intensive. You get muddy, you get wet, and at the end of the day, you’re happy to have processed your samples."
Johnson earned a bachelor’s degree in marine science and a Ph.D. in chemical oceanography from Texas A&M University. Her Ph.D. work helped assess whether nuclear waste released in the Arctic by the former Soviet Union migrated toward the Alaskan coastline. She also spent a short time working at Exxon as a geochemist before venturing back into teaching at Georgia Tech and Savannah State University.

Topics: Mars, NASA, Space Exploration, Spaceflight
Earlier today, our sun gained a new satellite, courtesy of SpaceX’s first test launch of its Falcon Heavy rocket: A cherry-red Tesla Roadster once driven by SpaceX and Tesla CEO Elon Musk, blasting tunes from David Bowie’s “Space Oddity” with a spacesuit-clad “Star Man” dummy strapped in the driver’s seat. On the dashboard display as it hurtled into the void? “Don’t Panic,” the tagline from Douglas Adams’ Hitchhiker’s Guide to the Galaxy.
Launched with an earth-shaking roar from Pad 39a at NASA’s Kennedy Space Center in Cape Canaveral, Florida—the same launch site of the Apollo 11 lunar mission in 1969 and the first space shuttle flight in 1981—the Roadster was boosted onto an interplanetary trajectory that takes it looping between the orbital vicinities of Earth and of Mars. It is neither the first car nor even the first electric model ever launched into space (the Apollo-era lunar rovers take both of those prizes). But it is certainly the fastest, approaching a speed of 12 kilometers per second relative to Earth when it separated from the Falcon Heavy’s payload fairing en route to deep space.
The big news here, though, isn’t actually the Falcon Heavy’s eccentric payload, but rather the mere fact that this behemoth of a rocket exists and is on the verge of regular operations. Musk, for his part, pegged the chances of success at only 50/50, where “success” was defined as the rocket merely flying high enough to clear the launch pad before exploding. In actuality, the rocket performed nearly flawlessly.

The Aerospace Engineer
Aprille J. Ericsson, Ph.D.
Deputy Instrument Manager
NASA Goddard Space Flight Center
As the deputy instrument manager for the ATLAS Instrument team at NASA, Aprille J. Ericsson leads development of an instrument to house satellite-based lasers used to measure the topography of ice sheets from space in order to measure global climate changes.
Ericsson, who holds a master’s of engineering and Ph.D. in mechanical engineering in aerospace from Howard University and who earned a bachelor’s of science in aeronautical/astronautical engineering from Massachusetts Institute of Technology, was previously one of the lead engineers on the concept study report for GEMS, or the Gravity and Extreme Magnetism Small Explorer. The unmanned observatory, which is scheduled to launch no later than April 2014, will be the first to measure polarized X-rays to study supermassive black holes and magnetars. Ericsson's work was influential in winning $105 million of funding for the project in 2009.
Ericsson was also the project engineer for LOLA, a lunar orbiter laser altimeter, which created an unprecedented topographic map of the moon’s landscape in late 2009.
“High school students need to be encouraged to do summer programs. If they have an interest in engineering or science they need to apply at field centers at NASA and NOAA so they get a feel for what they want to do," says Ericsson, who did the same at a young age. “It’s really important to have [hands-on lab] exposure as early as freshman and sophomore year. They perform better with their course work because they learn in an applied atmosphere."

Abstract
The Milky Way and Andromeda galaxies are each surrounded by a thin plane of satellite dwarf galaxies that may be corotating. Cosmological simulations predict that most satellite galaxy systems are close to isotropic with random motions, so those two well-studied systems are often interpreted as rare statistical outliers. We test this assumption using the kinematics of satellite galaxies around the Centaurus A galaxy. Our statistical analysis reveals evidence for corotation in a narrow plane: Of the 16 Centaurus A satellites with kinematic data, 14 follow a coherent velocity pattern aligned with the long axis of their spatial distribution. In standard cosmological simulations, less than 0.5% of Centaurus A–like systems show such behavior. Corotating satellite systems may be common in the universe, challenging small-scale structure formation in the prevailing cosmological paradigm.
