A cornerstone of physics may require a rethink if findings at the National Institute of Standards and Technology (NIST) are confirmed.
Toshiba and Cambridge University have been working together to find a cheaper and more efficient way to protect networks from criminal thievery and spying.
An international team of researchers has created ionized xenon atoms so positively charged that scientists involved in the study are now saying the existing theories need to be reexamined.
A research team led by the University of Vienna has developed a new method for entangling single photons that gyrate in opposite directions.
Studies by Berkeley Lab scientists of electron beam quality in laser plasma accelerators include novel tests for slice-energy spread
Scientists have demonstrated integrated arrays of emitters of "optical vortex beams" onto a silicon chip for the first time.
Interstellar travel for humans will depend upon extremely precise measurements of every factor of the mission.
Two physicists, one from the United States and one from France, were revealed on Tuesday October 9, 2012 as winners of the Nobel Prize in Physics.
Since 1927, when Werner Heisenberg formulated the uncertainty principle, it has stood as one of the cornerstones of quantum mechanics. It has also driven quantum physicists crazy for nearly a century.
An international team of researchers has achieved quantum teleportation over a record distance of 143 kilometers. The experiment marks a major step towards satellite-based quantum communication.
Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...
Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...
