“The THz nanoscope thus breaks the diffraction barrier by a factor of 1500”

Pistol shrimp blowing a blast of water a speed of 100km/h with temp 9900C (more)

“about 67 times as high as a typical MRI—without blowing itself to smithereens.”

The movie shows how an electron rides on a light wave after just having been pulled away from an atom. This is the first time an electron has ever been filmed, and the results are presented in the latest issue more...

The overall crappiness of the flame images, and more importantly, their placement and orientation have raised some serious concerns.

“The PageRank algorithm that first set Google on a path to glory measures the importance of a page in the world wide web. It’s fair to say that an entire field of study has grown up around the analysis of more...

“You can see the dampenning rods inserted in between the brightly glowing uranium fuel rods. Isn't the blue glow of the Cerenkov radiation pretty?”

“In the lens, the capacitors instead interact directly with electromagnetic waves like light. This sets up currents in the capacitors that focus the waves passing through the lens into a point 20 times smaller than their wavelength.”

With each bounce, the photon loses a little more energy and adds another 2P to the sail’s momentum. The photon can keep this up for thousands of bounces — in their paper, Meyer et. al. found that with reasonable assumptions more...

“"fast multipole method" developed for computational physics to rapidly estimate (to arbitrary precision) the conjugate gradient of an error function. (In other words, they tweak the parameters and "get a little better" the next time through the training data.)”

“Deep inside this mound there is an ex-to-be-very-secret Russian neutrino lab. It belongs to the Russian Nuclear Research Center and was build to explore the neutrino particle properties.”

“We have constructed a fully functional, fully integrated radio receiver, orders-of-magnitude smaller than any previous radio, from a single carbon nanotube.”

The damn thing doesn’t exist. And Mr Moulton, who apparently designed the thing as part of his Virginia Tech master’s thesis, didn’t even bother to check whether his design could possibly bloody work at all, even if you built it more...

Statistical Mechanics of Money, Income, and Wealth. In a closed economic system, money is conserved. Thus, by analogy with energy, the equilibrium probability distribution of money must follow the exponential Gibbs law characterized by an effective temperature equal to the more...
