Is it possible to create a perfect vacuum? - Rolf Landua and Anais Rassat
AdultsScienceTechnologyPhysicsThe universe is bustling with matter and energy. Even in the vast, apparent emptiness of intergalactic space, there's one hydrogen atom per cubic meter. But is there such thing as a total absence of everything? Is it possible to make a completely empty space? Rolf Landua and Anais Rassat explain the science behind vacuums.
Einstein's unique way of thinking contributed to his genius
AdultsPhysicsScienceRobbert Dijkgraaf is a theoretical physicist and Leon Levy Professor at the Institute for Advanced Study in Princeton. He is also the co-author of "The Usefulness of Useless Knowledge." In this video, he explains how Albert Einstein saw the world in a different way from how most scientists see it.
We Found Another State of Matter: The Supersolid!
AdultsScienceTechnologyPhysicsScientists have created, yet another state of matter called a supersolid! But what is it, and what does it do?
What is entropy? - Jeff Phillips
AdultsPhysicsScienceChemistryThere's a concept that's crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It's entropy, and it's notoriously difficult to wrap our heads around. Jeff Phillips gives a crash course on entropy.

Illuminating the Universe: The History of Light
AdultsHistoryTechnologyScience...Beyond what we can touch, taste, smell, and hear, we experience the universe through light. But how did we come to discover light, and how did we learn light's true nature, as the fastest thing in the universe, an electromagnetic spectrum, a wave and particle capable of the most amazing things? Here is the history of light, according to physics.
The Beginning of Everything -- The Big Bang
AdultsHistoryPhysicsSpace...How did everything get started? Has the universe a beginning or was it here since forever? Well, evidence suggests that there was indeed a starting point to this universe we are part of right now. But how can this be? How can something come from nothing? And what about time? We don't have all the answers yet so let's talk about what we know.
