This repository provides tools many tools to visualize relativity using TikZ. At the heart of it lies the definition of a specific TikZ argument that allows Lorentz transformations of arbitrary TikZ ...

Abstract: Geometric or Clifford algebra is a powerful, coordinate-free language for mathematical physics, offering more compact and insightful descriptions of natural laws than existing legacy ...

That's all from this live text as Barcelona come from 2-0 down to take the three points late on at Levante. We'll be back again tomorrow for more Premier League and La Liga action. See you then. FT: ...

What if you’ve already seen fragments of the future - without realizing it? In this thought experiment grounded in Einstein’s relativity, we unpack how a simple diagram changes our entire ...

Prof. Emeritus Howard Stein, a renowned philosopher and historian of physics at the University of Chicago, died March 8 at his home in Hyde Park. He was 95. A trained philosopher and mathematician, ...

We consider a quantum Otto engine using an Unruh-DeWitt particle detector model which interacts with a quantum scalar field in curved spacetime. We express a generic condition for extracting positive ...
