In this episode, Charlie and Jordan chat about rising sea levels, biodegradable "smart" implants and the existence of the pentaquark.
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?
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.
DNA Scientist and Mentor Bruce Jackson, PhD, traces ancestry and solves crimes with the powerful tool of DNA.
To detect dark matter called Weakly Interacting Massive Particles, or WIMPs, you have to go a long way - down!
Team upgrades sensitivity of the world's largest physics experiment.
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.
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.
It's build day for Colorado State University's Little Shop of Physics, and there's a whole lot of tinkering and experimenting going on.
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.
When it comes to ultrafast lasers, Margaret Murnane's name is one of the best known for her work in this field of science. The NSF's Ivy Kupec sat down with this well-published scientist who originates from County Limerick, Ireland to talk further about these uber speedy lasers, science and even Archimedes.
A light bulb has the glass carefully removed, leaving the glass base and filament intact. The bulb is connected to AC electricity, and the filament quickly and dramatically burns out. This leaves the two wires that originally supported the filament separated by the glass in the base. Take a propane torch and heat the glass base (the bulb remnants are still connected to the electricity), a point is reached where the heated glass is no longer isolating the two wires from each other, but has become a conductor of electricity. As the electricity flows, the heat generated lights up the glass, the propane torch can be removed, and the glass continues to glow very brightly.
A grape makes a great dipole antenna, and makes a great (small and safe) series of sparks in the microwave.
Passing a current through water makes hydrogen and oxygen, which fill a bubble that can be ignited.
An internally frosted, large light bulb is dipped into a fish tank of water, and the total internal reflection effect produces 'other-worldly' consequences to how the bulb looks in the water. The bulb goes from white to a silvery orb. Turning the bulb on, produces a similar, but more alluring effect.
A stream of air is used to levitate a small ball--and also a light bulb.
Passing a small electric current through a mechanical pencil lead causes it to glow brightly for several seconds.
You can push a knitting needle through a balloon if you take certain precautions.
