Boo! The optics behind "ghost" imaging « Skulls in the Stars
"Ghost imaging is in fact a fascinating and relatively new technique in which a detector can produce an image of an object that it cannot see! The physics behind this effect is somewhat subtle, and resulted in at least one minor controversy since its introduction. Let's take a look at it..."

Another dumb article on why spaceflight is bad for you -- KarlSchroeder.com
"But really, people, think! This doesn't mean that space flight is intrinsically dangerous. It means that badly shielded tin-can environments that aren't spun for gravity are a bad idea. And that is quite a different conclusion."

A Plea for Peaceful Coexistence - The Pour Blog - NYTimes.com
"Beer and wine are not in competition. Yet people in the wine business, who I assure you drink an awful lot of beer, don't often take it seriously as a beverage. And people in the beer business, perhaps in reaction to not-so-imaginary slights, rarely even acknowledge the existence of wine, much less deem it worthy of drinking."

Sexist Beatdown: The Happy Hooker, Or Why Doesn't Steven Levitt Suck Dick For a Living? - The Sexist - Washington City Paper
"[E]ven though our two Steves are really brilliant economists, they just can't figure out why most of us women don't want to have sex for tons and tons of money. Why aren't more women successful prostitutes?, Levitt and Dubner ask. Is it because:
a) They don't like sex;
b) They hate men;
c) They're kind of dumb;
d) All of the above.
If you guessed D, you are probably either Steven Levitt or Stephen Dubner. (Thanks for reading, guys!)"

Op-Ed Contributor - Bring Back Basketball's Little Big Men - NYTimes.com
"[I]f the N.C.A.A. truly cared about improving colleges instead of settling for the extra year before eligibility that Stern is talking about, it should use its considerable influence to demand that both the N.B.A. and N.F.L. foot the college's bill for training pro athletes by paying a given amount each year for each player successfully drafted from college. The money would go into a fund for academic scholarships at the colleges these players attended. It wouldn't perhaps turn young superstars into student-athletes,…
Elements I Have Yet to Use. In the Pipeline:
"I wrote about this topic a few years ago, and thought I'd update it. Many chemists find themselves looking at a periodic table and wondering "How many of these things have I personally handled?" My list is up to nearly 45 elements (there are a couple that I've got to think about, one-off catalyst reactions from twenty-two years ago and the like). And there are at least 29 that I hope to never use at all, since they're radioactive and I'm generally not in the mood for that. So what does that leave me?"

Historians Reassess Battle of Agincourt - NYTimes.com
"Agincourt's status as perhaps the greatest victory against overwhelming odds in military history -- and a keystone of the English self-image -- has been called into doubt by a group of historians in Britain and France who have painstakingly combed an array of military and tax records from that time and now take a skeptical view of the figures handed down by medieval chroniclers.

Deep Physics : Built on Facts
You can think of the earth's surface in New Mexico as subject to two superimposed sinusoidal periodic heat pulses. One has a period of 24 hours and corresponds to the heat rising and falling over the day/night cycle. The other has a period of 1 year and corresponds to the average heat changing through the seasons. Clearly this approximation is quite rough, but we can take it as a starting point for some mathematical spelunking of our own.

Myth Confirmed. : Built on Facts
"[U]ntil relatively recently, no one had ever actually done the experiment. It's difficult, both in terms of dropping the bullets properly and making sure the gun fires exactly horizontally. Horizontal fire is critical, because if there is an initial vertical velocity for the fired bullet, the equation will be different from the dropped bullet and they won't hit the ground at the same time. Nonetheless there is a group of experimenters who are very good at this sort of thing, and not so long ago they actually did the experiment. They are of course the…
Patrick Welsh -- To Explain the Achievement Gap, Examine the Parenting Gap - washingtonpost.com
"My students knew intuitively that the reason they were lagging academically had nothing to do with race, which is the too-handy explanation for the achievement gap in Alexandria. And it wasn't because the school system had failed them. They knew that excuses about a lack of resources and access just didn't wash at the new, state-of-the-art, $100 million T.C.

Analysis Of A Roulette Strategy
"As Hank explains in a recent article, when he visits a Casino he plays the Roulette. His simple strategy consists in betting on a single colour, doubling the bet every time he loses; when he wins, he starts back with the minimum bet.
Such a strategy is not going to make you rich, but no strategy does at the Roulette, especially the American one which has both a "0" and a "00" -two neutral numbers thrown in to enhance house odds. The idea of doubling every time is that eventually the colour you bet on is bound to appear, and you will win back all your fiches…

Electrons flow forever in metal rings - physicsworld.com
"[I]f a metal ring is very small - about 1 μm diameter or less - quantum mechanics says that its electrons should behave in much the same way as electrons orbiting an atomic nucleus. And in the same way that electrons in the lowest energy configuration of an atom maintain their orbits without the constant input of energy, electrons in such "mesoscopic" rings should flow forever. Indeed, a 1 μm diameter ring cooled to 1 K should support a current of about 1nA. "

"Thomas Jefferson was arguably one of the most well-educated Americans of his time. He was well-read, thoughtful, knowledgeable in a wide variety of topics from the arts to the sciences, and the founder of the University of Virginia. The same could probably be said of Ben Franklin, or James and Dolly Madison. On the larger world stage, we could credibly make such claims for René Descartes, William Shakespeare, Galileo, Michelangelo, and Plato.
But there is one thing unique about the education of all these…
