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." (Credit: Horgan)

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)
