This Week in Physics: Controlling Lightning and Other Curiosities

Quantum Theory: Einstein Saves the Quantum Cat (Jun 16) Einstein’s theory of general relativity will soon celebrate its 100th anniversary. Even after all these years it still captures the imagination of scientists. Researchers have now discovered that this theory can explain yet another puzzling phenomenon: the transition from quantum behavior to our classical, everyday world. The […]

The Unreasonable Effectiveness of Quantum Physics in Modern Mathematics

As the old saying goes, the laws of the Universe are written in the language of mathematics. This sentence often ascribed to Galileo illustrates the deep connection between physics and mathematics. When it comes to mathematics, as used by physicists, we often view it as simply a tool required to describe ideas in physics. But […]

This Week in Physics: Chiral Magnetic Waves and Physics of Basketball

New Evidence for Chiral Magnetic Waves (June  8) Researchers from the STAR collaboration at the Relativistic Heavy Ion Collider, a particle accelerator dedicated to exploring nuclear physics and the building blocks of matter, found new evidence for what’s called a “chiral magnetic wave” rippling through the soup of quark-gluon plasma created in an energetic particle smashups. […]
