An App For That...

...or, at least, there soon will be.
Do you feel nervous when you make a credit-card transaction using your mobile phone? Your worries could soon be a thing of the past, thanks to a low-cost device that could bring powerful cryptography to portable devices. That's the aim of Bruno Sanguinetti and colleagues at the University of Geneva in Switzerland, who have created a quantum random-number generator (QRNG) that uses low-cost electronic components including a mobile-phone camera.


Modern cryptographic protocols require the rapid generation of sequences of truly random numbers. These are used to create the "keys" that allow individuals to encrypt and decrypt sensitive information such as passwords and bank details. Coming up with these numbers is a significant technological challenge because computers are completely deterministic and are therefore not capable of creating truly random numbers. Cryptography systems tend to rely on "pseudo random-number" generators that output sequences of numbers that are nearly random. While some of these generators are very good, a cryptography system based on pseudo random numbers is easier to hack than a system that uses random numbers.

Truly random numbers can be generated by making measurements on physical systems that are inherently random – such as the radioactive decay of nuclei or noise in an electronic circuit. However, existing measurement techniques tend to be either very expensive or too slow to be of practical use. Securing your mobile phone, for example, needs a generation rate of about 1 kbit/s.

PARTICLE FEVER: a documentary film by Mark Levinson and David Kaplan

Source: Skeptic.com for synopsis



“Mind Blowing” — The New York Times



Particle Fever follows the inside story of six brilliant scientists seeking to unravel the mysteries of the universe, documenting the successes and setbacks in the planet’s most significant and inspiring scientific breakthrough.



Short Synopsis



Imagine being able to watch as Edison turned on the first light bulb, or as Franklin received his first jolt of electricity.



For the first time, a film gives audiences a front row seat to a significant and inspiring scientific breakthrough as it happens. Particle Fever follows six brilliant scientists during the launch of the Large Hadron Collider, marking the start-up of the biggest and most expensive experiment in the history of the planet, pushing the edge of human innovation.



As they seek to unravel the mysteries of the universe, 10,000 scientists from over 100 countries joined forces in pursuit of a single goal: to recreate conditions that existed just moments after the Big Bang and find the Higgs boson, potentially explaining the origin of all matter. But our heroes confront an even bigger challenge: have we reached our limit in understanding why we exist?



Directed by Mark Levinson, a physicist turned filmmaker, from the inspiration and initiative of producer David Kaplan and masterfully edited by Walter Murch (Apocalypse Now, The English Patient, The Godfather trilogy), Particle Fever is a celebration of discovery, revealing the very human stories behind this epic machine.

Deja Vu All Over Again...

Pro Publica (link below)

"It's Deja Vu, all over again." Yogi Berra

I was born in Winston-Salem, NC at Kate Bitting Reynolds Hospital (named after tobacco magnate R.J. Reynolds' sister-in-law) in 1962, one of about a dozen African American hospitals at the time in the US. I emerged in a segregated south eight years in the wake of Brown vs. Board of Education in Topeka, Kansas. Kate Bitting was also my mother's employer - she was an LVN. My father - a US Navy vet of WWII - was a line worker for the local textile mill, a vanishing industry in today's America, among contemporary others. They, like my older sister, who worked as a payroll analyst at R.J. Reynolds - earned retirements for their efforts and fidelity.



East of US 52 in Winston-Salem, NC, a neighborhood was established on Cleveland Avenue - the result of American Apartheid/Jim Crow - along with restrictive covenants preventing my parents from considering the purchase of a home in any other, more desirable location (or, ANY African Americans being in covenant-covered suburban hamlets after sundown).



I knew the Teflon kingpin "Po Charlie," and all his drug houses - I avoided entering them out of a respect for, and healthy fear of my parents. He brazenly announced when "5-0" was coming for a raid, knowing due to his paid informants in the department in those days, they'd find nothing. A switchblade pulled on my best friend and I by a young lady's brother - she had been the sad victim of a rape apparently, unbeknownst to me - generated a forked sprint by myself and my best friend: he up 19th street, I up 21st! (We joked about it over the phone later: he'd gotten to his home first.) I saw Charlie's minions and prostitutes plying their trades as I walked to school.

My heroes were segregated along with me: teachers, doctors, dentists, and clergy - the closest I'd ever get to Martin Luther King before or after his demise; listening to his fellow baptist ministers thunder jeremiads on the wrongs of society every Sunday morning. Education became important to me at its evident denial under "separate but equal": books decades out-of-date; written/crayoned in or pages missing. Our teachers at the time, pooled their own funds and stencil-copied (pre-Xerox tech) lessons to supplement the anvil-weighted chains southern gentility clanked tightly about our ankles. Our angels were determined we would not be denied.

My older sister - a student at Winston-Salem State Teachers College (now Winston-Salem State University) did like a lot of other young people, and put her life on the line numerous times (more than I care to remember) for the world we have today - some now myopically taking for granted, it's diversity and expanded freedoms have always been "here." Others now, descendant of this hierarchical privilege, fretting the universal constant - change - regretting and pining over a nostalgic utopia that on our side of town, never existed. 

"With all deliberate speed" meandered into North Carolina via forced busing when I left Fairview Elementary for Rural Hall finally in '71 - a former restricted covenant utopia. Looking at news reels of the high schools at the time: chains, baseball bats and fights; riots, teargas and protests - the older set-in-their-ways had more tumultuous adjustments to make, from those that had no problem with the established southern "order" to shackle us in place; simultaneously without thought or shame calling us "lazy." The world over, from Ireland, England and Nigeria with Boko Haram: extreme poverty, isolation, xenophobia, oppressive sexism, religious extremism and encouraged ignorance eventually breed gangs and violence.



"Welfare queen" entered the lexicon vis-a-vis "the gipper": cool conservatism was born in the B-movie actor-president, and the poster child of young conservative cool played by Michael J. Fox on "Family Ties." Due to that fictional example, it possibly contributed to Reagan/Bush Sr. taking more of the youth vote in their landslide victory against Walter Mondale and Geraldine Ferraro. It was "morning in America"; bigotry was "in" and Lee Atwater's "Southern Strategy" was modernized to be so attractive, coded, subtle in subterfuge and effective enough to attract black conservatives not discerning (or ignoring) his political Jujitsu.

"What's past is prologue." William Shakespeare 

No soon after a section of the voting rights act was gutted by the "Supreme Court" in the 21st century, southern states in the old confederacy enacted voting hurdles reflecting back to restrictive covenants in real estate, estimating soap bubbles and poll taxes. Sadly, so did my home state of North Carolina enact the most draconian ID laws on the flimsiest misappropriation of mathematics.



The problem is, we're no longer in the past. The Soviet Union fell in 1991 (though Vladimir is staging a nostalgic, oligarchic comeback). We are two years away from being second in the world to our banker, yet we're fighting openly and online, an uncivil war, that in the magical thinking of reestablishing "tradition"; "the-good-old-days" will funnel us all very quickly - strained through that filter of libertarian utopia example: Somalia -  down the drain of history...as a failed state.



ProPublica's Nikole Hannah-Jones details in her latest report how gerrymandering of school attendance zones and, surprisingly, support from a small pocket of black elites has transformed Tuscaloosa’s education system into a remnant of its former glory. Central High School today doesn’t have the same caliber of teachers or curriculum as its integrated sister school, Northridge. Central is also on a state watch list and has been plagued with low graduation rates -- all problems associated with segregated schools, which the Supreme Court thought it had addressed 60 years ago.

Magical Thinking...




The series COSMOS has been under heavy assault by science deniers from the first show. When science deniers on mainstream cable news (the ORIGINAL cable news, I might add) accuse Bill Nye of being "a bully," we've gone past the Rubicon; completely off-the-rails.



What precisely has this faux "knowledge" of intelligent design/young Earth/flat Earth/young Universe/dinosaur bones via Beelzebub/Mood Rings/vibrating crystals/telepathy and telekinesis/Loch Ness Monster/Leprechauns/UFOs/claims of faked Moon landings/pyramid-building aliens/unicorns/Bigfoot helped us "design"? Or patent for reproduction and consumption? When did boondoggle become science?



Has it generated any cures for cancer? A new electronic usage for graphene on the horizon? Room temperature superconductivity? Quantum supercomputers? A faster way to get to Mars? Near-warp drive? Or better yet: how are we going to supply drinkable water for an expansive, global population? Talk about "wars and rumors of wars": lack of resources has always resulted in human conflicts, especially when you have the bigger weapons.

Producing web sites and You Tube videos are entertaining, but they're not created for venues where they'll be torn apart; rigorously debated using the Scientific Method. They are not generated (or, inclined towards) solving any real-world important problems, and just because you have an "opinion," no matter how loudly you state it, it does not make it "fact."



Scientists, the 97% that have consensus on the subject, would LOVE to be absolutely wrong. Hurricanes Katrina/Rita/Irene/Sandy/____; droughts and fires (San Diego and southern California); melting polar ice caps and rising sea levels convince them otherwise. They live on the planet too, and have a vested interest - their own lives and their families - in the continuance of the human species.



Deniers - the 3% - are cock-sure they are "right." An estimate by a Anglican Archbishop found nowhere in the Bible becomes the unquestionable 6,000 year age of Earth, the Universe and stars (never mind the whole speed-of-light-red-shift-thing: they have Conservapedia to faux "refute" that). The excuses on AM talk radio from meat heads with no science background (and no degree period), are typically "the sun is getting hotter"; "we're going through a natural cycle," blah, blah, blah. A coworker at a previous company (a stochastic modeling firm)  could not believe the data I sent from the NOAA to refute their conspiratorial claims from a similarly-inclined "theory" site. Of course, in the same office was a moon-landing denier - who wasn't on the planet, mind you - but brimmed with male-member certitude the laptop-generated You Tube video on the conspiracy, requiring no doubt preternatural government thought control greater than a Vulcan mind-meld, was genuine (glad I don't work there anymore).



It's not a punchline to ask: what pray tell,is the plan B if the 3% are wrong, and it all blows up in our faces? I've stated the climate scientists have a vested interest - survival - in being off-the-mark. The fossil fuels industry funding the 3%-ers have a vested interest, too - money. "My bad" just won't do it if we screw this one away, more like "bend over and kiss your rear adios!"



Millennial voters will have to participate in representative democracy and make their voices known at the polls. They need to demand science literacy in those who wish to lead our nation going forward, and call politicians when the the same are clearly trying to BS their way into power. This is the only world the young know, and I think they'd like to inherit one somewhat intact.

“One of the saddest lessons of history is this: If we've been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even to ourselves, that we've been taken. Once you give a charlatan power over you, you almost never get it back.”

Separate Is Not Equal...



A salute to the 60th Anniversary of the Brown Decision, and Moral Mondays in my home state of North Carolina. The struggle obviously continues...

Segregated America





After the Civil War, millions of formerly enslaved African Americans hoped to join the larger society as full and equal citizens. Although some white Americans welcomed them, others used people’s ignorance, racism, and self-interest to sustain and spread racial divisions. By 1900, new laws and old customs in the North and the South had created a segregated society that condemned Americans of color to second-class citizenship.





Taking away the vote

Denying black men the right to vote through legal maneuvering and violence was a first step in taking away their civil rights. Beginning in the 1890s, southern states enacted literacy tests, poll taxes, elaborate registration systems, and eventually whites-only Democratic Party primaries to exclude black voters.



The laws proved very effective. In Mississippi, fewer than 9,000 of the 147,000 voting-age African Americans were registered after 1890. In Louisiana, where more than 130,000 black voters had been registered in 1896, the number had plummeted to 1,342 by 1904.




Poll tax receipt

Poll taxes required citizens to pay a fee to register to vote. These fees kept many poor African Americans, as well as poor whites, from voting. The poll tax receipts displayed here is from Alabama.



The Decision: A Landmark in American Justice



In 1952 the Supreme Court decided to hear school desegregation cases from across the country. When the trial began, everyone in the courtroom knew that the future of race relations in America hung in the balance. The attorneys for both sides believed that law and morality supported their arguments.



A victory by the plaintiffs would mean that the highest court in the land officially endorsed the ideal of equal opportunity, regardless of race. Defeat would mean that the Supreme Court continued to sanction a system of legal segregation based on the notion of racial inferiority.



“With All Deliberate Speed”



The Brown decision declared the system of legal segregation unconstitutional. But the Court ordered only that the states end segregation with “all deliberate speed.” This vagueness about how to enforce the ruling gave segregationists the opportunity to organize resistance.



Although many whites welcomed the Brown decision, a large number considered it an assault on their way of life. Segregationists played on the fears and prejudices of their communities and launched a militant campaign of defiance and resistance.

Thinking Science...



So, you won't think it's just me...

On the blog "Physics and Physicists," Zapper Z writes the following:

A while back, I started a series of blog entry titled "You Can Teach Yourself To Think Like A Scientist". In Part 3 of this series, I mentioned about the general principal that one might be able to draw when reading the statements made by a US Senator Marco Rubio of Florida. To refresh your memory, in a GQ Magazine interview, the senator was asked on how old he thinks the Earth is. He evaded answering the question by claiming that he's not a scientist, and that the issue has nothing to do with the economy of the US, which one would gather is the more important issue on his plate at that time.

Based on that interview, I tried to illustrate trying to extract the principals that Senator Rubio was using, which presumably are the principals that guide him in his decisions. His refusal to answer this question and based on his responses, one can conclude that he would rather defer such questions to experts. There's nothing wrong with that, and certainly, being put in a position like that, deferring to the experts is a rather smart way to respond to such a question.

However, such a principal no longer applies anymore, it seems. In the latest news report, it seems that Senator Rubio thinks that he's a climate expert.

"I do not believe that human activity is causing these dramatic changes to our climate the way these scientists are portraying it," Rubio said.

The dear senator is picking himself up from a personal debacle with tea party constituents, i.e. actually trying to solve problems with immigration reform, an effort he now absolves himself of.

The title of his blog entry is "US Senator Marco Rubio Shifts Position And Thinks He's A Climate Expert." A long title/URL I'll admit.

The point he's making is the convenience of duplicity; clearly demonstrable Orwellian doublespeak. The senator is obviously making a political calculation, not reporting facts, or new data that would make him reconsider the science.

Governor Romney was for climate change in Massachusetts, working to reduce the state's greenhouse gas emissions until he was against it to win his party's presidential nomination, and gaff about it at the GOP convention (kind of like his flip-flop on the public mandate regarding healthcare reform). Unfortunately, we cannot ignore it, nor couch the group into a witty comedic punchline.

At The Bottom of the World...

Sea level rise estimates are going to need to be revised upward: A portion of the West Antarctic Ice Sheet that is home to some of the fastest-flowing glaciers on the continent appears to have entered a state of retreat and melt that is “unstoppable,” two new studies have found.



It has passed the point of no return,” said Eric Rignot, lead author on one of the studies and a glaciologist at the University of California, Irvine, and NASA’s Jet Propulsion Laboratory.



The West Antarctic Ice Sheet has been of concern to climate scientists because it contains enough ice to add 10 to 13 feet to global sea level rise were it all to melt. (Because the ice sheet’s ice is bound to land, it increases the volume of the ocean as it flows into it, like ice cubes added to a glass of water; sea ice, on the other hand, doesn’t change the ocean’s volume as it melts because it is already displacing that volume, just as a melting ice cube doesn’t add volume to the glass.)

Reporting Science...

Media Bistro

An interview with Miles O'Brien and how science in an entertainment-driven media frequently gets reported, often by many who don't have a science background or training. Mr. O'Brien did bring his training as a history major and enthusiasm for getting stories accurate - he demonstrates his chutzpah during the interview. Miles sadly had a traffic accident where a portion of his arm had to be amputated afterwards, (he seems to be in good spirits). If anything, the interview gives perspective on how science is reported to the nation, what holds our attention and what we ultimately emphasize and deem as important. Unfortunately, it also describes quite well the tripartite Venn diagram between dogma, ignorance and science denial. Source: StarTalkRadio.net

Acoustic Tractor Beam...

Credit: Physics World (link below)

An acoustic "tractor beam" that can pull an object by firing sound waves at it has been created by physicists in the UK and US. The beam was made using a commercial ultrasound surgery system and differs from previous tractor beams that use light. The researchers say their technique could be readily adapted for medical applications that manipulate objects or tissue within the body.



The new tractor beam has been created by Mike MacDonald and colleagues at the University of Dundee, University of Southampton and Illinois Wesleyan University by using an ultrasound ablation system, which is normally used to destroy tumours thanks to focused beams of intense sound. First proposed in 2006 by Philip Marston of Washington State University and realized using light in 2010 by David Grier and colleagues at New York University, the technique involves firing two beams of ultrasonic waves upwards at a triangular-shaped target at about 51° either side from the vertical direction. The target is shaped such that the beams bounce off opposite sides of the triangle, causing the reflected sound to travel straight up (see figure "Reflecting beams").

Saturn Opposition...

Image Source: Link below

On May 10, at 2 p.m. EDT, Saturn reaches opposition — the point in its orbit when it lies opposite the Sun as seen from Earth. The planet then appears as a bright yellowish object at magnitude 0.1 in the constellation Libra the Scales. In the Northern Hemisphere, that star pattern rises in the southeast at sunset.



As you might guess, opposition means the planet rises at sunset, climbs highest in the south around 1 A.M. local daylight time, and sets as the Sun comes up. Opposition also brings Saturn closest to Earth, so it shines brightest for the year (at magnitude 0.1). During times of good seeing (atmospheric steadiness), an observer can pick out the more prominent features of the globe and rings through a 3-inch telescope.



There’s no rush to do this. An apparition (observing season) of Saturn spans a bit more than 10 months. The current one began in late November 2013 when Saturn emerged from the solar glare in the morning sky. The planet will remain visible until October, when it will sink too low in the west after sunset for useful observations.

Mother's Day (re post and add)...

An anniversary, of sorts...

History of Mother's Day



"The first official Mother's Day celebrations in the United States took place in West Virginia in 1908, at the urging of Anna Jarvis. Anna's mother (also named Anna), who was active in her community, frequently organized women's groups to promote friendship and health. It had been her dream to reunite families divided by the Civil War with a day dedicated to mothers. When she passed away on May 12, 1907, Anna held a memorial service at her late mother's church in her honor. Her mother's idea of Mother's Day quickly caught on, and within five years of her death, virtually every state was observing the day on the anniversary of her death. In 1914, President Woodrow Wilson declared the second Sunday of May as the official Mother's Day.



"You can do anything you want to do, if you set your MIND to it. You can do all things through Christ who strengthens you." Mildred D. Goodwin, sunrise 15 September 1925, sunset 7 May 2009, laid to rest 12 May 2009.



Despite my challenging background, she said this often, and believed the quote I reproduced above, and more importantly: she (my MVP) believed in me. I am ever grateful that even as the light was fading from your eyes, you knew who your children - my sister and I - were.



Mildred: Her name means "gentle strength." She was that. Her name for me was "stink": diapers. You understand.

Nuclear Fusion With Hammers...


Michel Laberge’s favorite type of energy is the nuclear energy. And the reason for that, as Laberge discusses in this recent TED talk, is that it is the energy of the future. Today nuclear energy generates close to 20% of electricity in the US, but that is, of course, done through nuclear fission. Nuclear fusion, on the other hand, is thefuture of nuclear power, however generating energy in such a way is a gargantuan task for the engineers. There are many potential ways of harnessing the power of the atom and Michel Laberge offers a rather interesting one. High speeds, scorching temperatures and crushing pressure produced by synchronized hammers is the key of Laberge’s idea.

Loop Quantum Cosmology...


This classic video discusses the rapidly growing field of loop quantum gravity or, more generally, loop cosmology. The main idea behind loop quantum gravity is that space-time is granular and that such granularity is a consequence of quantum mechanics. The powerful implication of this, if, of course, the theory turns our to be correct, is that quantum theory and general relativity can be joined together in what is usually called quantum gravity. Such a powerful junction of the two fields would enable cosmologists to answer some fundamental and almost esoteric questions, for instance, what was the nature of the big bang and what caused it. This video introduces the main ideas of the field and the leading experts, including their interviews.

Expanding the Alphabet...

Image source: Huffington Post Science

For billions of years, the history of life has been written with just four letters — A, T, C and G, the labels given to the DNA subunits contained in all organisms. That alphabet has just grown longer, researchers announce, with the creation of a living cell that has two 'foreign' DNA building blocks in its genome.



Hailed as a breakthrough by other scientists, the work is a step towards the synthesis of cells able to churn out drugs and other useful molecules. It also raises the possibility that cells could one day be engineered without any of the four DNA bases used by all organisms on Earth.



“What we have now is a living cell that literally stores increased genetic information,” says Floyd Romesberg, a chemical biologist at the Scripps Research Institute in La Jolla, California, who led the 15-year effort. Their research appears online today in Nature.

El Niño...

Source: NOAA's El Niño Page

The El Niño / La Niña climate pattern that alternately warms and cools the eastern tropical Pacific is the 800-pound gorilla of Earth’s climate system. On a global scale, no other single phenomenon has a greater influence on whether a year will be warmer, cooler, wetter, or drier than average. Naturally, then, the ears of seasonal forecasters and natural resource managers around the world perked up back in early March when NOAA’s Climate Prediction Center issued an “El Niño Watch.”



The “watch” means that oceanic and atmospheric conditions in the tropical Pacific Ocean are favorable for the development of El Niño within the next six months. These maps reveal one of the most significant of those favorable signs: a deep pool of warm water sliding eastward along the equator since late January.



As the warm surface water is pushed westward by the prevailing winds, cool water from deeper in the ocean rises to the surface near South America. This temperature gradient—warm waters around Indonesia and cooler waters off South America—lasts only as long as the easterly winds are blowing.



If those winds go slack or reverse direction in the western Pacific, the warm pool of water around Indonesia is released and begins a slow slosh back toward South America. The slosh is called a Kelvin wave. If the Kelvin wave has a strong impact on the surface waters in the central and eastern Pacific, then it can help change the atmospheric circulation and trigger a cascade of climatic side effects that reverberate across the globe.

Ununseptium...

Credit: Lawrence Livermore National Laboratories

The official Periodic Table of the Elements is one step closer to adding element 117 to its ranks. That’s thanks to an international team of scientists that was able to successfully create several atoms of element 117, which is currently known as Ununseptium until it’s given an official name.



The paper for this experiment has been published in Physical Review Letters.



Ununseptium, like many superheavy elements near the end of the periodic table, is incredibly unstable, existing only for fractions of a second before decaying into other elements. In fact, scientists didn’t actually observe any atoms of element 117 – its existence was confirmed by its decay. Indeed, the elements that 117 decays to themselves decay.



As part of the Periodic Table, Ununseptium would be considered a Group VII element, putting it in the same family as flourine, bromine and chlorine.

Battle of Puebla - Wikipedia

Cinco de Mayo (Spanish for "fifth of May") is a celebration held on May 5. It is celebrated nationwide in the United States and regionally in Mexico, primarily in the state of Puebla, where the holiday is called El Dia de la Batalla de Puebla (English: The Day of the Battle of Puebla). The date is observed in the United States as a celebration of Mexican heritage and pride, and to commemorate the cause of freedom and democracy during the first years of the American Civil War. In the state of Puebla, the date is observed to commemorate the Mexican army's unlikely victory over French forces at the Battle of Puebla on May 5, 1862, under the leadership of General Ignacio Zaragoza Seguín. Contrary to widespread popular belief, Cinco de Mayo is not Mexico's Independence Day—the most important national patriotic holiday in Mexico—which is actually celebrated on September 16. (Wikipedia)



The National Society of Hispanic Physicists has a recognition page of Hispanic Americans in Physics - Past, Present and Future. Similar to what I posted during the month of February, my intention is to give the same attention to Hispanic Scientists and Engineers during the celebration of National Hispanic Heritage Month.

Almost 10 years before "Brown vs. Board of Education," Sylvia Mendez and her parents helped end school segregation in California. An American citizen of Mexican and Puerto Rican heritage who spoke and wrote perfect English, Mendez was denied enrollment to a "Whites only" school. Her parents took action by organizing the Hispanic community and filing a lawsuit in federal district court. Their success eventually brought an end to the era of segregated education in California.

Tyranny of Authoritarians...

Image Source: The Graveyard Site

This was inspired by my read of the old COSMOS on my kindle. I happened upon this letter excerpt from Galileo to the Grand Duchess Christina of Tuscany, 1615. Given the unbelievable, relentless assaults on the new show by Young Earth/Universe Creationists, Galileo might as well have been writing this letter in the 21st Century:



To the Most Serene Grand Duchess Mother:



Some years ago, as Your Serene Highness well knows, I discovered in the heavens many things that had not been seen before our own age. The novelty of these things, as well as some consequences which followed from them in contradiction to the physical notions commonly held among academic philosophers, stirred up against me no small number of professors-as if I had placed these things in the sky with my own hands in order to upset nature and overturn the sciences. They seemed to forget that the increase of known truths stimulates the investigation, establishment, and growth of the arts; not their diminution or destruction.

.

.

.

Now as to the false aspersions which they so unjustly seek to cast upon me, I have thought it necessary to justify myself in the eyes of all men, whose judgment in matters of` religion and of reputation I must hold in great esteem. I shall therefore discourse of the particulars which these men produce to make this opinion detested and to have it condemned not merely as false but as heretical. To this end they make a shield of their hypocritical zeal for religion. They go about invoking the Bible, which they would have minister to their deceitful purposes. Contrary to the sense of the Bible and the intention of the holy Fathers, if I am not mistaken, they would extend such authorities until even m purely physical matters - where faith is not involved - they would have us altogether abandon reason and the evidence of our senses in favor of some biblical passage, though under the surface meaning of its words this passage may contain a different sense.

Pseudo Gap Superconductors...

Argonne National Laboratory

Thanks to a new study by the U.S. Department of Energy’s (DOE) Argonne National Laboratory, researchers have identified and solved at least one paradox in the behavior of high-temperature superconductors. The riddle involves a phenomenon called the “pseudogap,” a region of energy levels in which relatively few electrons are allowed to exist.



Despite their name, high-temperature superconductors are actually quite cold – roughly 250 degrees to 350 degrees below zero Fahrenheit. Conventional superconductors, like those used in MRI machines or particle accelerators, are even colder. Even though they are still quite cold, high-temperature superconductors are of special interest to researchers because, at least in theory, they are much easier to keep sufficiently cold and are thus potentially more useful.

Flying cars have long been the stuff of science fiction, though plenty of entrepreneurs and visionaries have struggled to make the concept a reality – including no less than the original Henry Ford.



The group of Massachusetts Institute of Technology alumni that developed the Transition flying car have said they’re ready to take a giant leap even farther into the wild blue yonder. They’ve announced a more advanced concept, the TF-X, that is rapidly working its way toward reality.



To start with, the four-seater would be capable of vertical take-offs and landings. And since it would largely be controlled by a central computer network, the TF-X would, claims a Terrafugia promotional video, require a pilot/driver to have as little as five hours of training, a slight fraction of what it now takes to get the most basic private pilot’s license.



Oh, and if that isn’t appealing enough, the team says their newest flying car design would use an environmentally friendly plug-in hybrid powertrain.
