As for the forces, electromagnetism and gravity we experience in everyday life. But the weak and strong forces are beyond our ordinary experience. So in physics, lots of the basic building blocks take 20th- or perhaps 21st-century equipment to explore. – Edward Witten
One of the biggest challenges we had in the first decade was not that many people had personal computers. There werent that many people to sell to, and it was hard to identify them. – Steve Case
