What is entropy? - Jeff Phillips

AdultsPhysicsScienceChemistry
There'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.
