Lenses and mirrors have the wonderful property that light coming in from an ultra-distant source that's perpendicular to the plane of the mirror gets focused in such a way that it reaches your ...

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 ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This article is more than 7 years old. When I woke up Sunday ...

Quantum gravity gradient sensor used outdoors to find tunnel “Conventional imaging captures only as much light as the lens aperture can accept, and it necessarily loses directional information since ...

The researchers reduced the mirrors’ relative motions to about 10.8 phonons, or quantum units of vibration, close to the zero-phonon quantum limit.

Charge Radius of Neutron-Deficient Ni54 and Symmetry Energy Constraints Using the Difference in Mirror Pair Charge Radii. Physical Review Letters, 2021; 127 (18) DOI: 10.1103/PhysRevLett.127.182503 ...

Curved Lens vs. Flat Mirrors There are predominantly two types of telescopes: those that rely on lenses, and the second and more advanced class that depend on mirrors.

A lens on physics and its enthusiasts His photographs show scientists and experiments, large physics facilities and tiny devices, enthusiastic crowds of conference participants and lone researchers ...
