educational link

i just wanted to share a link to the site done by daniel shiffman this guy has the theoretical physics understanding on a very deep level and the programming ability to express it visually in simulation. And he has gone to the trouble of allowing everyone to be able to visualize a huge array of fundamental physical interactions without the sheer amount of dedication and effort it must of taken him to get that far.

So to the point anyone that visits the site will be guarenteed to learn something new, which is always good.
