Latest Photon Stories
In celebration of the publication’s 25th anniversary, Physics World has selected the five most important physics-related discoveries of the past quarter-century, as well as five recent breakthroughs with the potential to change the world.
A quantum computer can solve tasks where a classical computer fails.
University of Calgary scientists have overcome an 'Achilles' heel' of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets.
Without the currently available plethora of X-ray methods, basic research in the physical sciences would be unthinkable.
Researchers at the University of Rochester have measured for the first time light emitted by photoluminescence from a nanodiamond levitating in free space.
One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still.
Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday objects.
“Why? The Single Photon Theory” explains the nature of time, space and consciousness. PUERTO RICO (PRWEB) July 22, 2013 For author Zaid Díaz
Almost 200 years ago, Bavarian physicist Joseph von Fraunhofer discovered dark lines in the sun's spectrum. It was later discovered that these spectral lines can be used to infer the chemical composition and temperature of the sun's atmosphere.
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...
