Another Approach To Understand Accelerated Motion
Motion of a moving particle is considered to be one of the most instructive and useful physical systems one can study. In a real world case, such systems may exhibit immense complexity and intractability. But if we are lucky, we may be able to isolate the moving particle from unwanted

How to Compute the General Relativistic Correction to Time
General relativity is one of the most technically difficult physics theories, as it requires uncommon knowledge and mathematical skills. However, it is possible to calculate the relativistic effects induced by the curvature of space-time with good precision, and even to derive its formula, with a few simple arguments. We know

Beyond Noether’s Theorem: The Physics of Broken Symmetries
Back in June, I wrote this article about Noether’s Theorem, the idea that continuous symmetries and conservation laws are intrinsically linked. But, while Noether’s Theorem is one of the most beautiful concepts in physics, symmetries themselves are equally as fundamental, and often similarly beautiful. And further, much of

What, Exactly, is Entropy?
Entropy is a bit of a buzzword in modern science. Usually it is used as a synonym for “disorder,” but it is so much more interesting than that.
