An introduction on laser physics
Categories: Physics Optics LaserSo I want to start a series of posts that will focus mostly on lasers, what they are, how they work, what are the most important elements, etc... It can still evolve....

What it means to have a PhD in France
Categories: GeneralI was reading an article from Le Monde about the state of French research, especially the despair of French doctorates, and what it means. As you might have seen if you have read my bio, I am French, and I have a doctorate, although not from a French University but from EPFL in Switzerland.

How to direct lightning with a laser
Categories: General Physics OpticsClimate change is a mess. It's hotter in some places, colder in other, and in general, severe weather is intensifying with longer droughts, heavier rainfalls and stronger storms. This problem, caused mostly by our method of generation of energy relying on burning fuel and releasing carbon dioxide in the air has a few solutions, among them: the wind turbine to harvest wind energy and generate clean...
