This is a series of informal videos by the distinguished physicist Sean Carroll with the purpouse "to make our brains active" in these pandemic times. You can find the videos in his blog's page.
The series is growing with a new video every week and a Q&A video for each one main video.
I liked a lot all the videos up to now and in particular the fourth video dedicated to the concept of "Space" (and the following Q&A one). Here you can find a nice explanation of the Lagrangian and the Hamiltonian approach and in particular of the importance of putting position and momentum on equal footin in the Hamiltonian approach. Infact this make possible to ask very deep questions about the world, questions you would'nt have asked following the Newtonian approach such as "Why do we leave in space? Why not in momentum space?".
I think those videos are an important resource for understanding physics! Thanke you prof Carroll.
