Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

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 ...

In this video, we explore five key areas of physics: **Classical Mechanics:** Newton’s second law (F = ma) explains the relationship between force, mass, and acceleration. The law of universal ...

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

Physicists at Stevens Institute of Technology used Christiaan Huygens' 350-year-old theorem, which explains the workings of pendulums and planets, to reveal new properties of light waves. (Courtesy: ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

In 1900, German theoretical physicist Max Planck accidentally gave birth to the field of quantum mechanics (aka quantum physics) when he tried to investigate why the results of his black body ...
