Knowledge without frontiers is an organization founded by Jean-Pierre. It is full of funny comic books on mathematics, physics and engineering.

Music

Pete Lockett has explored percussion across the world and has interesting material for a musician. The information is not superficial and is quite useful for a self learner.
