STEVE! Dude take it easy! No matter what anyone says, it only their opinion! You seem to be very defensive in regards to this topic.
I totally agree that Einstein was a genius! But what renorm (i think) and I are stressing is that he is slightly over exemplified in physics (for God knows what reason). If you study the biography of people like Sir Issac, you'll see that he became the greatest mathematician in the world in about 18 months from scratch!
Also I recommend reading "The Infinite Book" by John Barrow. As impossible, nonsensical and outrageous as infinity might be, the basic principles of calculus and other mathematical branches will cease to exist without it.
So my children, learn to embrace it
