A team of physicists built a new interferometer to measure how gravity affects quantum wave phases by putting atoms in a superposition of free-fall and stationary paths, addressing long-standing questions about the compatibility of quantum mechanics and general relativity.
An interactive web-based simulation that sets the speed of light to 5 km/h, allowing users to experience relativistic effects like length contraction and time dilation in a walking-paced environment.
Brown University chemists provide direct spectroscopic evidence that Einstein's theory of relativity blurs the distinction between sigma and pi bonds in heavy elements like bismuth, challenging textbook explanations.
