What do we learn about physics in this experiment at ETH Zurich? The two acoustic mirrors on the Hönggerberg campus show on a large scale how experiments with tiny particles work in physics labs. The ...

In physics many subtle phenomena can be studied by allowing waves to interfere with each other. In an interferometer, light waves travel by two different paths, directed from place to place by ...

Quantum mechanics usually applies to very small objects: atoms, electrons and the like. But physicists have now brought the equivalent of a 10-kilogram object to the edge of the quantum realm.

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This article is more than 9 years old. When I woke up Sunday morning, ...

Lightweight and low cost: researchers have developed a new way to make telescope mirrors that could enable much larger, and thus more sensitive, telescopes to be placed in orbit. (Courtesy: Sebastian ...

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where a particle does not have a single definite value of position or momentum ...

A team of physicists experimentally produces quantum-superpositions, simply using a mirror. Standing in front of a mirror, we can easily tell apart ourselves from our mirror image. The mirror does not ...

Go find a makeup mirror. There's a good chance you have one in the bathroom. You know the type—it has a surface that shows you a zoomed-in image of your face. If you have one nearby, you can use this ...

This is a Physics unit worksheet package for Grade 10 Science. These optics worksheets are 19 pages long and contain answers. The topics include: light theory, light calculations, images, reflection, ...
