Reversing Entropy with Maxwell’s Demon

Ultimately, entropy is a measure of the availability of free energy – of energy that isn’t hopelessly mixed in thermal equilibrium. Pump energy into a small system and complexity can thrive..


Time Crystals!

In this episode of the Space Time Journal Club Matt discusses how two independent research teams created their own Time Crystals, a form of matter that breaks time translational symmetry and could be used in quantum computers.


Psychokinetically Picking Your Path

A request I see a lot of people ask online a lot are things they can try with psychokinesis. In most places, this question tends to go unanswered where people inexperienced with psychokinesis will shift the conversation to an irrelevant topic that has nothing to do with psychokinesis. This article is about a simple and fun psychokinetic exercise that can be expanded into more advanced techniques and teaches manipulation of complex things. Instead of going in-depth on what random walks are, I am going to include a few useful videos made by people more qualified to explain it than me Read More


Why Quantum Information is Never Destroyed

If you have perfect knowledge of every single particle in the universe, can you use the laws of physics to rewind all the way back to the Big Bang? Is the entire history of the universe perfectly knowable? Or has information somehow lost along the way?


Noether’s Theorem and The Symmetries of Reality

Conservation laws are among the most important tools in physics. They feel as fundamental as you can get. And yet they’re wrong – or at least they’re only right sometimes. These laws are consequences of a much deeper, more fundamental principle: Noether’s theorem.


Entropy

Have you ever been doing thermodynamics in a closed system and noticed that there’s a finite number of ways that things can be arranged, and they tend towards disorder? Of course you have, we all have. That’s entropy. And here in our Universe, entropy is on the rise.
