I stumbled upon his really amazing video of the processes that go on with in a cell. It is amazing how complex processes go on inside tiny little cells inside your body and you are not even aware of it all. That is one of the reasons I am so into biology, it is just fascinating the systems and processes that go on. They are so much more complex than anything that humans have been able to replicate. The first video shows the process with music. The second explains the entire thing (I added this one in for nerds like me).
