(PhysOrg.com) -- For over half a century, physicists and computer scientists have been troubled by a theoretical concept set forth by Rolf Landauer. He suggested that the very act of erasing a bit of memory in a digital system ...
(PhysOrg.com) -- Until now, scientists have thought that the process of erasing information requires energy. But a new study shows that, theoretically, information can be erased without using any energy at all. Instead, the ...
(PhysOrg.com) -- Scientists in Japan are the first to have succeeded in converting information into free energy in an experiment that verifies the "Maxwell demon" thought experiment devised in 1867.
(PhysOrg.com) -- Maxwell’s demon may be making a comeback. Physicists know that the demon, an imaginary creature that decreases the entropy of a system, cannot exist in macroscopic systems due to the energy it requires ...
(PhysOrg.com) -- According to the second law of thermodynamics, entropy always increases. For example, two bodies of different temperatures, when brought into contact, will eventually mix together to result in a uniform temperature. ...
An idea conceived by one of the world's greatest scientists nearly 150 years ago has finally been realised with a tiny machine that could eventually lead to lasers moving objects remotely.
