The EPR paradox, that we met in a previous video, tells us 2 entangled particles can effect each other no matter now far away they are. But then why cant we use them to send instant messages across the universe? Einsteins relativity...

Peritrich Ciliates Masters of Long-Range Snacking

NIST physicist Krister Shalm talks about NIST's participation in the November 30, 2016, BIG Bell Test, a worldwide project to bring human unpredictability (randomness) to cutting-edge physics experiments. But it's not just NIST...

We've gone through some of the main advancements in modern physics, which brings us to the here and now! What are physicists currently working on? One huge area of interest is developing a quantum field theory for the gravitational...

Signaling across synapses--the tiny gaps between neurons, over a thousand times thinner than a sheet of paper--requires multiple molecules to work together. To learn how neurons communicate, and ensure they pass across the synapses at...

Why are missions like OSIRIS-REx bringing pieces of an asteroid back home?

Parker Solar Probe Mission Scientist Adam Szabo discusses NASA's journey to the Sun.

This video explains the concept of heat energy and its role in temperature and phase changes. The video also highlights how heat energy is responsible for phase changes, using the example of water transitioning from solid ice to liquid...

Space Facts II puts viewers on the forefront of space exploration, examining its role on Earth in fighting forest fires, controlling diseases (such as diabetes), combating air pollution and mapping solar and lunar cycles. This video...

On Sept. 22, 2017, the National Science Foundation's IceCube Neutrino Observatory alerted the international astronomy community that a high-energy neutrino had passed through the Earth. That notification set in motion follow-on...

Researchers using NASA's Fermi Gamma-ray Space Telescope have discovered the first gamma-ray pulsar in a galaxy other than our own. The object sets a new record for the most luminous gamma-ray pulsar known.



The pulsar...

Volcanic ash can become a multimillion-dollar nightmare, lingering in the skies, getting into engines and damaging aircraft. Volcanic ash is known to present hazards to aviation, infrastructure, agriculture, and human and animal health....

On June 19, the CERN Council in Geneva Switzerland approved the construction of a new 100-kilometer circular supercollider called the Future Circular Collider.

With NASA planning to send astronauts to the Moon by 2024, Steve Mackwell chats about the Moon’s exciting unexplored areas.

This video explains how substances move in and out of cells via diffusion, which is the net movement of particles from an area of high concentration to an area of low concentration. The video first defines diffusion and illustrates it...

Yaireska Collado-Vega leads a team at NASA’s Goddard Spacecraft Center that is studying the solar weather environment so that robots and people exploring space can be protected. In this episode of Gravity Assist, she describes the...

Many students have been taught that prepositions are never left behind a sentence or a question. However, there is no rule which states this. There are some cases where we need to put a preposition at the end of a sentence or a...

Electromagnetic force down, three more forces to go! Which one is next? Why it's the strong nuclear force, famous for keeping atomic nuclei together. What kind of particles will be involved in this quantum field theory? Let's find out.

Get ready for one of the weirdest things in modern physics. Particles that pop into existence from nothing and then go back to nothing again! This is happening all the time, all around you and even inside of you. It's the quantum foam,...

New paper proposes megalodon may have gone extinct due to supernova explosion

In this video, a teacher and a student demonstrate how to test the turbidity of water using a turbidity sensor. They explain that turbidity measures the particles suspended in water and how it can affect the health of aquatic life. The...

Dr. Leonard A. Cole is an expert on bioterrorism and on terror medicine. He is an adjunct professor at Rutgers New Jersey Medical School (Emergency Medicine) and at Rutgers University-Newark (Political Science). At the medical school he...

Bubbling air through sand can cause it to act like a liquid. Dianna Cowern and William Osman try to reproduce this popular GIF on Physics Girl. Sand liquefied!

Weve talked about the quantum state plenty- but what happens to it over time? Thats exactly the question the Schrodinger equation solves. This video we talk about Linearity. In the next video we discuss the equation itself and its...
