Quantum gravity expert says “philosophical superficiality” has harmed physics

Carlo Rovelli: "Theoretical physics has not done great in the last decades. Why? Well, one of the reasons, I think, is that it got trapped in a wrong philosophy."

Pairing old technologies with new for next-generation electronic devices

The scientists reported a 40-times-larger effect than previously achieved in semiconductor materials, with the largest value measured comparable to a record high value of the spin-Hall effect observed in heavy metals such as Platinum. (Credit: UCL London Centre for Nanotechnology)

Beyond energy, matter, time and space

New particles may yet be discovered, and even new laws. But it is almost taken for granted that everything from physics to biology, including the mind, ultimately comes down to four fundamental concepts: matter and energy interacting in an arena of space and time. (Credit: Carl Wiens)

‘Quantum Bounce’ theory claims black holes explode

Kepler's Supernova Remnant "On October 9, 1604, sky watchers -- including astronomer Johannes Kepler, spotted a "new star" in the western sky, rivaling the brilliance of nearby planets. "Kepler's supernova" was the last exploding supernova seen in our Milky Way galaxy.

LLNL researchers define boundaries for petawatt laser absorption

Lawrence Livermore physicist Hui Chen sets up targets for an experiment using petawatt laser technology at the Jupiter Laser Facility.

How the Aged Vacuum Tube Could Save Moore’s Law

One of the bulbs Thomas Alva Edison used to discover thermionic emission (the Edison Effect) in 1884. Edison found when he connected an ammeter between the filament and the auxiliary electrode, a current would flow, passing through the evacuated space of the bulb from filament to electrode. This current was later found to consist of electrons.
