If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...

During its teenage and young adult years—what is now referred to as its “classical” period—physics made a lot of mistakes. In the old physics, mass and energy were separately conserved; particles’ ...

Physicists have built a quantum gas that behaves nothing like the substances we are used to, and that is exactly why it is causing such excitement. Instead of slowing down when particles collide, this ...

Out with the old: Many undergraduate physics curricula need revamping. (Courtesy: iStock/Pobytov) Physics education has a high inertia towards change. While high-school students in today’s biology ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...
