This film demonstrates the measurement of the speed of light in both air and water using experimental setups. The first ...

When we measure the speed of light, it's always in two directions. Measuring it in one direction may be impossible.

The planet WASP-121b is extreme. Its a gas giant almost twice as big as Jupiter orbiting extremely close to its star50 times ...

Heading to Myrtle Beach, South Carolina this spring? From red-light cameras to speed limits, here are five traffic laws every ...

Physicists measure the mass of subatomic particles ... W bosons are made by smashing beams of particles together at nearly the speed of light inside powerful particle colliders like the Tevatron ...

Online tests of women's reaction times offer insights into cognitive function and could help fill data gaps on early cognitive problems, potentially shedding light on dementia development later in ...

For several years now, scientists have been using lasers to control the properties of matter at extremely fast rates: during one optical cycle of a light wave. But because these changes occur on the ...

Analysis: Measuring time to the 19th decimal place ... These beams contain many different waves of light, whose frequencies are equally spaced out, like the teeth of a comb – hence the name.

Beaux Collins profiles as a late-round NFL draft pick at best, but the impact he made in his one season in South Bend should ...

The asynchronously dual-comb generated in a single fiber laser cavity is a powerful tool for simplifying coherent measurements, as common-mode ...

These electronic copilots can pick up incoming speed traps and red-light cameras, and that’s just the beginning.

and processing speed. It's not only an anatomic measure; the changes we see in the anatomy are associated with changes we see in the cognition of these individuals." In the study, Irimia and co ...
