Retroreflector transmits light with negligible power consumption
Improving lasers with microring mirrors
Metamaterials used to make metamirrors capable of reflecting one frequency and ignoring all others
Team develops new water splitting technique that could produce hydrogen fuel
A University of Colorado Boulder team has developed a radically new technique that uses the power of sunlight to efficiently split water into its components of hydrogen and oxygen, paving the way for the ...
How to test the twin paradox without using a spaceship
Forget about anti-ageing creams and hair treatments. If you want to stay young, get a fast spaceship. That is what Einstein's Theory of Relativity predicted a century ago, and it is commonly known as "twin ...
Research group figures out a way to film a laser in normal air bouncing off mirrors (w/ Video)
Researchers demonstrate proof of creation of a mirror by optical matter
Anti-mirror optical illusion could increase LED luminosity and laser power
New measurement of electron–quark scattering
From matching wings on butterflies to the repeating six-point pattern of snowflakes, symmetries echo through nature, even down to the smallest building blocks of matter. Since the discovery of quarks, the ...
New method of producing stereoisomers developed
Mathematician designs event cloaking device without using metamaterials
From heat and cold comes image and mirror image
Many chemical compounds exist as an image and a mirror image: they differ in their spatial orientation, like the left and right hand. The properties of these so-called chiral molecules are also often quite different – synthesising ...
Light, instead of electrodes, could control deformable mirrors
Math professor's side mirror that eliminates 'blind spot' receives US patent
A side mirror that eliminates the dangerous "blind spot" for drivers has now received a U.S. patent. The subtly curved mirror, invented by Drexel University mathematics professor Dr. R. Andrew Hicks, dramatically ...
