Reading the Comics, April 20, 2015: History of Mathematics Edition

This is a bit of a broad claim, but it seems Comic Strip Master Command was thinking of all mathematics one lead-time ago. There’s a comic about the original invention of mathematics, and another showing off 20th century physics equations. 619 more words

Does the temperature of a particle increase as it is accelerated to relativistic speeds?

Temperature is a macroscopic quantity. It is meant that temperature is a property of a collection of particles. We can only talk about the temperature of atoms that make up an object. 49 more words

Modern Physics: Chapter 6 - The Heisenberg Uncertainty Principle

One of the best explanations I’ve found of the Heisenberg uncertainty principle is in Volume III of the Feynman Lectures on Physics. Read the following sections (which I’ve linked) to understand the general concept behind it: 92 more words
