Physics simulators. Lots of physics simulators.

PhET - Physics Education Technology offers this astoundingly large library of online physics simulations. Play orbital billiards. Land on a cheesy moon. Experiment with sound. Or try more advanced quantum physics simulators. Still bored? Try the "cutting edge" catagory. Here's the complete index. (Warnings: Frames, Flash, Javascript, Java applets, graphics, sound, quantum timesuck.)

"We're space explorers, and we need space!"

Where did you want to live when you grew up? If you're like me, you read Clarke's SF classic, Rendezvous with Rama (soon to be a major motion picture?). Donald E. Davis took what we dreamed about and illustrated it, for NASA. His depictions of O'Neill Cylinders, Stanford Tori, and Bernal Spheres are in the public domain (and make excellent desktop wallpaper).

Hubble ACS, We Hardly Knew You

Hubble's ACS Has Died. Hubble's Advanced Camera for Surveys has apparently gone into safe mode, with little hope of return. The ACS was installed in 2002, and added amazing upgrades to Hubble's imaging capabilities. Though its lifespan was only projected at five years, scientists had hoped it would hold out longer. Though a final shuttle servicing mission is scheduled for 2008, the mission objectives plate is already too full to consider its repair. Alas, more of those beautiful pictures (as well as extended research capabilities) will have to wait until the James Webb Space Telescope is launched in 2013.

A delightfully nerdy page for nerds

Dr. James B. Calvert, professor emeritus of engineering at the University of Denver, has an incredibly rich and deep personal webpage, which includes such gems as Latin for mountain men, the correct corn-hog ratio, travel by brachistochrone, anomalous sound propagation and the guns of Barisal, and about a billion other awesomely nerdy topics.

Virgin Birth? No, Virgin Hatch.

A virgin birth? No, but a virgin hatch. The process by which this happened is nothing new, but appears to be the first recorded instance in this species. Maybe this phenomenon could also help solve a controversial human problem.

Cancer

Cheap, safe drug kills most cancers. That's the good news. The bad news is that because there's no patent and it's so cheap to make, researchers may not be able to get funding from the private sector for further research since the treatment wouldn't make a profit. [Via Hullabaloo.]

Truth in advertising

Is Airborne science or snake oil ? The official website is flashy, but short on empirical evidence, and even admits that there is "no cure" for the common cold. The first doubts were from ABC News.

Neanderthals & Modern Humans Interbred. Hybrid Skull Unearthed in Romania ...
... that includes features of both modern humans and Neanderthals, possibly suggesting that the two may have interbred thousands of years ago. Neanderthals were replaced by early modern humans. Researchers have long debated whether the two groups mixed together, though most doubt it. The last evidence for Neanderthals dates from at least 24,000 years ago

Kinseyian mathematics, of a kind

The "Darwinian paradox" of homosexuality presents the conundrum of how a potential genetic basis for homosexual behavior could provide a survival benefit to offpsring and extend through generations, when sexual reproduction would seem to place strong selection pressure against such a "gene". Recently developed mathematical models (PDF) from researchers Sergey Gavrilets and William Rice not only show how a "gay gene" might proliferate within a population, but also provides testable hypotheses, including predictions of "widespread bisexuality" (subscription req'd).

Your boyfriend must have solved the problem for you.

"Ben Barres's work is much better than his sister's," one scientist remarked to another. The only problem is that Ben Barres and his “sister” Barbara Barres were the same person. An FTM transsexual offers a unique view of the impact of gender discrimination in science, having seen it from both sides. Despite the fact that recent studies have shown that a woman has to be 2.5 times as productive to be judged as scientifically competant as a man in the sciences, many still argue that there is actually a level playing field, a source of some frustration for many women in the field. (For a somewhat easier to read and referenced response to the Physics Today letters, check out Evalyn Gates’ reply at the end.)

Beyond Belief

Beyond Belief. Google Video of the complete proceedings of the conference Beyond Belief: Science, Reason, Religion and Survival, which took place on November 5-7, 2006 at the Salk Institute in La Jolla, California. (There are ten sessions, which average about two hours each.) Bios of the speakers who attended. A NYT article on the conference: "By the third day, the arguments were so heated that Dr. [Melvin] Konner was reminded of 'a den of vipers.' " Further conversation concerning the conference, in which Scott Atran writes, "I find it fascinating that among the brilliant scientists and philosophers at the conference, there was no convincing evidence presented that they know how to deal with the basic irrationality of human life and society other than to insist against all reason and evidence that things ought to be rational and evidence based. It makes me embarrassed to be a scientist and atheist."

The Secret Life of Machines and the amazing Tim Hunkin

All the episodes of The Secret Life of Machines are available online. Created by engineer, artist, tinkerer and cartoonist Tim Hunkin, the show took a look at the science and mechanics behind common household objects, with a bit of social history, homemade laboratory experiments, and downplayed humor. The series grew out of a long-running strip, which Hunkin has now offers as his own cartoon encyclopedia. You can also try some experiments of your own, marvel at the coin-operated contraptions he made for the Under the Pier Show in Suffolk (don't miss the film), and read his thoughts about his brief foray into the fine art world and his ruminations about how art and engineering mix.

The Lights in the Sky Are Stars

Universe Today is a news site for astronomy geeks. Don't miss its sibling, the Bad Astronomy Forum, which not only features examples of bad astronomy, but also discussions of space exploration and astrophotography. (If you like astrophotography, you're probably already aware of NASA's astronomy photo of the day.) But my favorite part of the whole site is the free astronomy eBook, What's Up 2007: 365 Days of Skywatching. If only it would only stop raining, maybe I'd grab some binoculars and go outside for some stargazing...

A day to be thankful for resublimated thiotimoline.

Think you get a lot done? Isaac Asimov (pronounced like "has, him, of" without the h's) , who would have turned 87 today, wrote or edited over 500 books, including science-fiction novels, introductions to organic chemistry (a field in which he held a professorship at B.U.) , indispensable anthologies of early science fiction, jokebooks, guides to Shakespeare, and collections of lively essays on science that have introduced thousands of people to the pleasures of thinking hard about the universe. He also found the time to write a few essays and write postcards to his fans. His story "Runaround" , from his 1950 collection I, Robot, is the only piece of fiction I know centered on the properties of a differential equation. His Foundation Trilogy was given a special Hugo award in 1966 as the best science fiction series of all time; a movie version, to be written by Jeff Vintar and directed by Shekhar Kapur, is currently in development.

“Allowing parents to select their children’s sexual orientation would further a parent’s freedom to raise the sort of children they want to raise.”

Cure for teh gay? I was relaxing in front of X-Men 3 when a friend mentioned that the United States "gay sheep" experiments were wrapping up (though not uneventfully), with considerable successes. Lesbian tennis champ Martina Navaratilova has been fighting to end the tests for some time, but it appears a "gay vaccine" for pregnant mothers may be inevitable. Meanwhile, the GOP's only gay congressman retires.

A Happy Family is a World's First

"There are few world firsts nowadays, but it may be one." - A quote used to describe triplets born to a woman with two wombs. Double uterus is an uncommon condition that is often undetected until a woman becomes pregnant. The outcome for such pregnancies is usually good, though posing a higher risk for breech positioning. The odds of triplets (twins in one womb, one fetus in the other) are 25 million to one.

Billions and Billions... of Blog Posts

Carl Sagan has a posse. Today marks the ten year anniversary of the passing of Carl Sagan, scientist and popularizer of science, and bloggers are planning to mark the day with posts about the man and how he's affected their lives. The initiative has the blessing of at least one member of the Sagan clan, and has already spawned a site where those without blogs of their own can post their thoughts online. Yes, Sagan could be prickly at times, and there might have been things he could have been more open about in his lifetime. But few scientists have done more to bring science to the public. These days, we could use another of him. Maybe two.

Medics face death in Libyan HIV case

Death by firing squad is imminent (timeline) for a Palestinian doctor and five Bulgarian nurses accused of infecting 426 girls and boys at the al-Fatah Hospital in Benghazi with HIV, after having the sentence lifted a year ago and sent to retrial. Libya stands accused of using the children as diplomatic pawns and torturing confessions out of the health workers. Nature has published a series of articles refuting the dubious evidence provided by Libyan researchers, which many think was concocted to cover up the poor hospital hygiene that likely caused the infections in the first place.

Moonbase: Alpha

NASA Plans Permanent Moonbase. The base, a potential stepping stone for further Mars exploration, will likely be situated near one of the poles. The advantages of a polar site (pdf) include a relatively moderate climate, possible hydrogen and oxygen resources, unexplored terrain and abundant solar power. They have apparently abandoned plans to use nuclear reactors, which is probably for the best.

Renaissance bling

The King's Kunstkammer - en vogue in Renaissance Europe, kunstkammers were status symbols of kings, vast collections of art, curiosities, and scientific and natural objects. This is a partial reconstruction of the Royal Danish Kunstkammer, established by King Frederik III in the mid-1600s. Exploring the collection's 250 objects offers insight into princely preoccupations of the era.

Biggest breakthroughs of the next 50 years

What will be the biggest scientific breakthroughs of the next 50 years? As part of their 50th anniversary celebration, the New Scientist asked 70 prominent minds for ideas on the subject. You can read the thoughts of scientists like Freeman Dyson, Benoit Mandelbrot and Jane Goodall individually, or browse by topic. For example, eight thinkers have something to say about alien life. The links to browse by topic can be found at the beginning of the main link. Also, compare with this thread about similar predictions from 1950.

Interspecies fun (and benefits)

Neanderthal Lovin’! New research from evolutionary scientist Bruce Lahn suggests that humans and the now extinct Neanderthal species mixed, and humans snatched up a valuable brain gene in the process. (The gene, MCPH1, and Lahn, discussed last year on MeFi) This comes on the tails of yet another new study providing morphological evidence that there was nontrivial interbreeding between humans and Neanderthals in Eurasia, despite the fact that Neanderthals may have been genetically closer to chimps than humans. Contrary to popular imagination, though, the Neanderthal species had bigger brains and sophisticated intellects, at least roughly on par with that of human beings. The gene regulates brain size during development, but its exact utility to humans is still unknown (and controversial). The origin of this gene and the question of Neanderthal mixing will soon be answered more definitively by the, just launched, 2 year project to map the Neanderthal genome, headed by Svante Pääbo (profiled in recent Smithsonian and Wired articles). Pääbo calls Lahn’s study "the most compelling case to date for a genetic contribution of Neandertals to modern humans."

Physics for Future Presidents is a class taught at UC Berkeley by Physics professor Richard Muller. It's a class specifically for non-physics majors and teaches the real world results of the sometimes impenetrable math involved in university physics.
