The Unlikely Correctness of Newton’s Laws

April 30, 2014Article3569 vuesEdit
Do moving objects exhaust? Does the Moon accelerate? How strong is the gravity pull of the Moon on the Earth compared to that of the Earth on the Moon? While we've all learned Newton's laws of motion, many of us would get several answers of these questions wrong. That's not so surprising, as Newton's laws are deeply counter-intuitive. By stressing their weirdness with Veritasium videos, this article dives into a deep understanding of classical mechanics.

Spacetime of General Relativity

June 02, 2013Article10309 vuesEdit
Most popular science explanations of the theory of general relativity are very nice-looking. But they are also deeply misleading. This article presents you a more accurate picture of the spacetime envisioned by Albert Einstein.

Does God play dice?

May 28, 2013Article933 vuesEdit
For Albert Einstein, the answer is no. But what did he mean? Has the greatest theoretical physicist of all time really missed the bandwagon of quantum physics? What are the real issues of the controversy that has opposed him to the Copenhagen School (Bohr, Heisenberg ...)? Back to the physics of the early twentieth century, its history, philosophy and ideas.

Dynamics of the Wave Function: Heisenberg, Schrödinger, Collapse

March 04, 2013Article5492 vuesEdit
On one hand, the dynamics of the wave function can follow Schrödinger equation and satisfy simple properties like Heisenberg uncertainty principle. But on the other hand, it can be probabilistic. This doesn't mean that it's totally unpredictable, since the unpredictability is amazingly predictable. Find out how these two dynamics work!

The Essence of Quantum Mechanics

January 21, 2013Article7874 vuesEdit
Quantum mechanics is the most accurate and tested scientific theory, Its applications to real life are countless, as all new technologies are based on its principles. Yet, it's also probably the most misunderstood theory, because it constantly contradicts common sense. This article presents the most important features of the theory.

Spacetime of Special Relativity

October 14, 2012Article2442 vuesEdit
Einstein's theory of relativity is the best-known breakthrough of the History of science. The reason for that isn't only the accuracy of the theory, but also and mainly its beauty. As Einstein once said: "Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone." This is what the article aims at showing Einstein's simple ideas of special relativity and their beauty.

The forces of Nature: from Newton to String Theory

September 27, 2012Article1671 vuesEdit
We live in a very complex universe, and as far as one can remember, men have always wanted to know everything about it: where do we come from? what is our world made of? To answer these questions, sciences were developped, and among them, theoretical physics: using mathematics to describe certain aspects of Nature. From […]
