The second law of thermodynamics - the law that entropy must, on average, increase - has been interpreted as the inevitability of the decay of structure. This is .... misleading. Structure can develop in one region even as the entropy...

Cosmologist Sean Carroll attacks -- in an entertaining and thought-provoking tour through the nature of time and the universe -- a deceptively simple question: Why does time exist at all? The potential answers point to a surprising view...

In today’s episode we’ll explore thermodynamics and some of the ways it shows up in our daily lives. We’ll learn the zeroth law of thermodynamics, what it means to reach a thermal equilibrium, and define the first law of thermodynamics....

In this video Paul Andersen explains how objects in contact with varying temperatures will eventually reach thermal equilibrium with equal temperatures. The amount of thermal energy transferred is related to the mass and temperature of...

The common interpretation of entropy is that it is a measure of disorder in the universe. The universe is on path to more and more disorder. And this is the reason time is thought to flow forward.Is entropy a...

In this video, we’re exploring the link between information and entropy, by examining a famous thought experiments by James Clerk Maxwell, called Maxwell's demon, which seems to show that entropy can be reversed. In...

The video is a lecture on thermal equilibrium and infrared radiation. The lecturer discusses how a body can remain at constant temperature, the relationship between temperature and radiation emitted by a body, and how the temperature of...

You've heard of the laws of thermodynamics, but did you know there are actually four of them? It's true, and since they already had laws one, two, and three, but then wanted to formulate another more fundamental one, the number right...

Now that we're done with circuits, we are going to talk about heat transfer and temperature. This video explains the laws of thermodynamics and covers the three methods of energy transfer (conduction, convection, and radiation, as well...

We all know what it's like to feel hot or cold. But what is hot? What is cold? What does temperature really measure? Don't pretend like you haven't lost sleep over this. Well you don't have to fret any longer, Prof Dave will take you...
