Anyone trying to build sandcastles on the beach will need some degree of skill and imagination, but not an instruction manual. The water content is actually relatively unimportant to the mechanical…

I have just completed the first in a series of youtube video's on quantum theory. This one deal with quantum states. In these video's I attempt to explain quantum mechanics in a way that anyone who…

Black holes are massive gravitational fields in the universe that result from the collapse of giant stars. Because black holes absorb light, they cannot be studied using telescopes or other…

When something is moving close to the speed of light, the fastest anything can move, sending ahead information in time to make mid-path flight corrections sounds impossible. Not quite, say…

Squeeze a crystal of manganese oxide hard enough, and it changes from an electrical insulator to a conductive metal. In a Nature Materials report, researchers use computational modeling to show why…

Optical clocks might become the atomic clocks of the future. Their "pendulum", i.e. the regular oscillation process which each clock needs, is an oscillation in the range of the visible light. As…

Ten years ago, astronomers made the stunning discovery that the universe is expanding at a faster pace today than it did in the past. “Explaining why the expansion of the Universe is currently…

Cosmologists at the University of Illinois say ancient light absorbed by neutral hydrogen atoms could be used to test certain predictions of string theory - but they'll need a gigantic array of radio…

An international research team has discovered that a magnetic field can interact with the electrons in a superconductor in ways never before observed. Andrea D. Bianchi, the lead researcher from the…

For the past 40 years, light-emitting diodes have been successfully employed wherever small amounts of light are needed. Present-day applications include car indicators, reversing and brake lights.…
