Physics

Physics is the science of matter, energy, space and time. It looks both inward and outward, from the smallest subatomic particle to the vastness of the universe—and yet it is also intensely practical. Physics begins with the everyday physical world around us—the blue of the sky, the colors of the rainbow, the fall of an apple, the motions of the moon. What's happening here? Why do things work this way?

Are invisibility cloaks possible?

Have you ever wished you could hide under an invisibility cloak like Harry Potter or conceal your car with a Klingon cloaking device like in "Star Trek"?

Einstein's clocks

In this video, Fermilab's Don Lincoln shows that every single day particle physicists prove that moving clocks tick more slowly than stationary ones.

Large scale graphene production

Draw a line with a pencil and it's likely that somewhere along that black smudge is a material that earned two scientists the 2010 Nobel Prize in Physics.

Dancing droplets (audio only)

Watch as coalescing droplets dance themselves off of hydrophobic thin fibers, a new phenomenon first witnessed at Duke University

GUTs and TOEs

Albert Einstein said that what he wanted to know was "God's thoughts," which is a metaphor for the ultimate and most basic rules of the universe.

Big mysteries: dark energy

Scientists were shocked in 1998 when the expansion of the universe wasn't slowing down as expected by our best understanding of gravity at the time; the expansion was speeding up!

The pentaquark

In episode 20, Charlie and Jordan chat about rising sea levels, biodegradable "smart" implants and the existence of the pentaquark.

What is a semiconductor?

Semiconductors are in everything from your cell phone to rockets. But what exactly are they, and what makes them so special? Find out from Jamie, a Ph.D. student in Electrical Engineering and Computer Science at MIT.

The LHC: A stronger machine

Watch CERN engineers explain the work during the laboratory's long shutdown to prepare the Large Hadron Collider (LHC) to run at a higher collision energy of 13 TeV. Teams are working hard for the upcoming restart. The first circulating beams of protons in the LHC are planned for the week beginning 23 March, and first 13 TeV collisions are expected in late May to early June.

The search for the origin of dark energy

Members of the Dark Energy Survey collaboration explain what they hope to learn by studying the southern sky with the world's most advanced digital camera, mounted on a telescope in Chile.

Center for Computational Relativity and Gravitation

The Center for Computational Relativity and Gravitation at the Rochester Institute of Technology is dedicated to research the frontiers of numerical relativity and astrophysics and gravitational wave physics. The Center is funded in part by the National Science Foundation and integrates state-of-the-art science, performance computing and scientific visualization.
