[rain] it's actually schrödinger but i'll let it pass and WE HAVE FACTUAL INFORMATION ABOUT LUXEMBOURG HOW CAN YOU STILL SAY IT'S A MICROSTATE

Q: Whats the relationship between entropy in the information-theory sense and the thermodynamics sense
Physicist: The term Entropy shows up both in thermodynamics and information theory, so since thermodynamics called dibs, Ill call thermodynamic entropy entropy, and information theoretic entropy information. I cant think of a good way to demonstrate intuitively that entropy and information are essentially the same, so instead check out the similarities Essentially, they both answer the question how hard is it to describe this thing. In fact, unless you have a mess of time on your hands, just go with that. For those of you with some time, a post that turned out to be longer than it should have been: Entropy Back in the day a dude named Boltzmann found that heat and temperature didnt effectively describe heat flow, and that a new variable was called for. For example, all the air in a room could suddenly condense into a ball, which then bounces around with the same energy as the original air, and conservation of energy would still hold up. The big problem with this scenario is not that it violates any fundamental laws, but that its unlikely dont bet against a thermodynamicist when they say somethings unlikely. To deal with this Boltzmann defined entropy. Following basic probability, the more ways that a macrostate things like temperature, wind blowing, big stuff with lots of molecules can happen the more likely it is. The individual configurations atom 1 is exactly here, atom 2 is over here, are called microstates and as you can imagine a single macrostate, like a bucket of
