Physicists Trace Origin of Electromagnetic Interaction
An international group of physicists have traced the origin of an electromagnetic interaction to the Dirac Equation, which is a fundamental equation of quantum physics. “The new finding, published as a rapid communication in the journal Physical Review B, advances the fundamental understanding of magnetic systems as well as multiferroics, which can change their electrical … [Read more...]
China Producing World’s Largest Radio Telescope
A large engineering and scientific project in China, led by the country’s military-led space program, is creating the world’s largest radio telescope, which will be able to detect radio signals from tens of billions of light years away. The Telescope is known as FAST, which stands for Five-hundred-meter Aperture Spherical Telescope. When the project is complete, the dish on the … [Read more...]
‘Electrosmog’ to Help Power Devices in UK
Paul Drayson, a former British science minister, has developed a device that captures “electrosmog” (invisible clouds of electromagnetic radiation), and uses it to power small devices. The energy-harvesting system is known as Freevolt. Freevolt uses an antenna to gain power from multiple wavebands of the electromagnetic spectrum. This is the first commercial device that is … [Read more...]
