One of the things he was bothered by was the long-held belief of Aristotle that
objects, including the Earth, naturally come to rest unless they are forced to move by
an external force(the motion of the other planets was considered special- they had the
property of quintessence so that their natural state was to move in circles). One thing
that bothered Copernicus is that nobody could imagine a force large enough to keep the
Earth moving around the Sun. Galileo and Newton understood that objects had inertia-
that they tended to keep moving in a straight line at constant speed (or sit still) unless
acted on by an external force- in the cases of objects 'naturally' coming to rest, friction
was identified as the responsible force. So for the Earth, there doesn't need to be an
external force to keep it moving, just so long as it isn't being affected by friction. As we
will learn in subsequent chapters, gravity is what keeps the Earth moving in an ellipse
around the Sun rather than just moving through space in a straight line.
There was another prevailing argument against the moving Earth. It went something
like this: if the Earth were to move around the Sun, it would have to be traveling at
speeds of around 30 km/s to make it all the way around in one year (that bit's pretty
much right). People argued that if a bird were to drop from a tree to snatch up a worm,
and it took one second for it land, the Earth would have therefore moved some 30 km
out from under the bird, leaving it mighty confused in a neighboring county just before
it met with a presumably unpleasant and messy landing. Since birds had been observed
to drop from trees to eat worms, with confusion and harm coming only to the worm,
people argued that there was no way the Earth could be moving around the Sun. What
these people did not understand is the concept of relative motion: the bird and the air
were moving around the Sun, with the Earth at 30 km/s, so the velocity of both the bird
and air, relative to the Earth, were basically zero (not counting a gentle breeze or the
bird's downward velocity as it fell).

Why did Albert Einstein use playing dice as an analogy for quantum mechanics?
Clasical mechanics states that, IN THEORY, one can predict the outcome of an event (like the roll of two dice) if you had enough information before hand. Quantum mechanics states that you can only predict the PROBABILITY of an event, no matter how much information you gather. And it is NOT a matter that we are not clever enough to devise an experiment to get a result, or that the object "knows" the answer but that we can't figure it out -- it is that the result is inherently unknowable.Decades of experiments have shown that QM is the correct way to predict results -- that they are only probabilities is frustrating, but the fact remains is that it works but classical mechanics does not.Einstein knew that QM gave proper predictions, but was troubled by the idea that our Universe operated under purely probabilistic laws. He felt that there HAD to be a more basic law, underlying the observed probabilistic results. In a 1926 letter to Max Born, Einstein said, "Quantum mechanics is certainly imposing. But an inner voice tells me that it is not yet the real thing. The theory says a lot, but does not really bring us any closer to the secret of 'the old one.' I, at any rate, am convinced that He does not throw dice."
