In a recent experiment at the University of Nebraska-Lincoln, plasma electrons in the paths of intense laser light pulses were almost instantly accelerated close to the speed of light. Physics professor Donald Umstadter, who led the research experiment that confirmed previous theory, said the new application might aptly be called an “optical rocket” because of…
Why a Single Nuke’s Impact Shouldn’t Only Be Measured in Megatons
Researchers Harness Heat to Power Computers
One of the biggest problems with computers, dating to the invention of the first one, has been finding ways to keep them cool so that they don’t overheat or shut down. Instead of combating the heat, two University of Nebraska–Lincoln engineers have embraced it as an alternative energy source that would allow computing at ultra-high…
