Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world ...

Students stretch pre-cut rubber bands to their lips, stretch the rubber bands, and then allow them to contract. The rubber bands grow warmer as they expand and cool as they contract. To Conduct ...

Professor Brian Cox explains the concept of entropy and the arrow of time. He uses a pile of sand to explain how entropy is the measure of how many ways in which something can be rearranged. He then ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

We study the experimental design problem of selecting a most informative subset, having prespecified size, from a set of correlated random variables. The problem arises in many applied domains, such ...
