Here, a calcite crystal is struck with a laser operating at 445 nanometers, fluorescing and displaying properties of birefringence. Unlike the standard picture of light breaking into individual ...

Scientists at Nanyang Technological University in Singapore have discovered a surprisingly simple way to create exotic light ...

While the terms "quantum physics" and "Theory of Relativity" are used casually every day, not many people know what they really mean. Yet these theories have had a profound impact not only on science ...

In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley failed to measure the speed of Earth by comparing the speed of light in ...

Researchers at the Hebrew University of Jerusalem have overturned a 180-year-old scientific assumption, proving that the magnetic component of light plays a critical role in how light interacts with ...

Is it possible to travel faster than the speed of light? A recent experiment appeared to show just that. This video breaks ...

How does color work, and how does the type of light source you use affect the colors you see? Appliance Science looks at the science of light and color. Richard Baguley Richard Baguley has been ...

Can we turn back time? Ask a savvy physicist, and the answer will be “it depends.” Schemes for retrograde time travel abound but usually involve irreconcilable paradoxes and rely on outlandish ...

Physics is the study of the underlying laws and mechanisms explaining how the universe works. Most of what we do in daily life is based on a principle or law of physics—dealing with forces, motion, ...
