Still remember about the 2024 Olympics in Paris? A French physicist is going to fix the problems of Niels Bohr’s atom cake.

I actually visited Denmark this summer and had quite a nice experience. There were plenty of sites related to the twentieth century physics world.

In short, the Danish boy Niels Henrik David Bohr found a quantized version of an atom. Discontinuity, an important characteristic of quantum theory has been introduced to the world. Note: Niels Bohr will pop up continually in the upcoming episodes, so do t forget about him!

There is a revolution waiting ahead. The quantum theory will play a major part in it. The third battle is far from over. Groups of geniuses in the early twentieth century are ready to give us a big surprise, and a brand new physics.

The wave theory is rising! Two geniuses and several experiments quickly changed the trajectory of history. Surprise attacks were launched frequently, soon leaving the corpuscular theory with nothing to hold on to. A century after its dominance, a new king was about to emerge.

What is light? People have thought about this question for centuries. Some considered it a kind of wave and others were determined to prove that its nature is a kind of particle. In the seventeenth century, a major battle between the two sides was started.

How can light stimulate electric currents? Einstein gave us the answer. Planck who was the rebel suddenly turned against his own theory. The age of quantum mechanics was started.

This episode continues in the black body radiation problem and delves into the theory and its impact.

Max Planck made a revolutionary discovery of the formula of black body radiation which gave a start to modern physics

Saved this episode for Christmas Eve! ( the truth is I have just finished the draft the day before yesterday.)
