Breaking the Planck's law, at the nanoscale

(PhysOrg.com) -- A well-established physical law describes the transfer of heat between two objects, but some physicists have long predicted that the law should break down when the objects are very close together. Scientists ...

Image: A mysterious ring of celestial microwaves

Fifty years ago, astronomers discovered a mystery. They called it Loop I. Today, we still have not fully resolved the mystery of how this giant celestial structure formed but we do now have the best image of it, thanks to ...

Spacetime—a creation of well-known actors?

Most physicists believe that the structure of spacetime is formed in an unknown way at the Planck scale, i.e., at a scale close to one trillionth of a trillionth of a metre. However, careful considerations undermine this ...

Redefining the kilogram

New research, published by the National Physical Laboratory (NPL), takes a significant step towards changing the international definition of the kilogram – which is currently based on a lump of platinum-iridium kept ...

Cliches about nations govern our actions

Germans arrive at every appointment 5 hours before the scheduled time, all Indians are called Ranjid and have a red mark on their foreheads, the Japanese bow 10,000 times a day, and Americans all speak with chewing gum in ...

Discovery of uncertainty relations beyond the Heisenberg

In the quantum world, the famous Heisenberg uncertainty principle bounds the product of the variances of two incompatible observables such as the position and the momentum of a particle by the Planck constant. Heisenberg, ...
