Breaking Bell's Inequality with Monte Carlo Simulations in Python

Marton Trencseni - Sun 01 September 2024 • Tagged with physics, quantum, mechanics, qubit, entanglement, epr, bell

The article explains the Bell inequality using Monte Carlo simulations in Python, and shows how non-local action-at-a-distance can be used to break it with entangled qubits.

Einstein's amazing theory

Marton Trencseni - Tue 16 February 2016 • Tagged with physics, einstein, relativity

This post is about the amazing success of Einstein's general theory of relativity. The theory predicts, among other things the accelerating Universe, black holes, gravitational lensing and gravitational waves. The real shocker is to remember that Einstein didn't invent general relativity to explain these. He didn’t know about these, they didn't exist at that time!
