Latest Photon Stories
Researchers at the California Institute of Technology (Caltech) have proposed a new paradigm that should allow scientists to observe quantum behavior in small mechanical systems.
Researchers are devising instruments and protocols to assess the impact of nanoparticles on the environment and human health before they are sent to market.
MIT researchers have developed a new way to tune the frequency of lasers that operate in the terahertz spectrum - an important step toward airport scanners that could tell whether a vial in a closed suitcase contains aspirin, methamphetamines or an explosive.
To exploit the quantum world to the fullest, a key commodity is entanglementâ€”the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another.
The first experiments are now underway using the world's most powerful X-ray laser, the Linac Coherent Light Source, located at the Department of Energy's SLAC National Accelerator Laboratory.
BIRMINGHAM, N.J., Oct.
During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity.
A team of Harvard chemists led by X. Sunney Xie has developed a new microscopic technique for seeing, in color, molecules with undetectable fluorescence.
Chaotic behavior is the rule, not the exception, in the world we experience through our senses, the world governed by the laws of classical physics.
A team of UniversitÃ© de MontrÃ©al researchers, led by physics PhD student Olivier Daigle, has developed the world's most sensitive astronomical camera. Marketed by Photon etc., a young Quebec firm, the camera will be used by the Mont-MÃ©gantic Observatory and NASA, which purchased the first unit.
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...
