The "paradox" is only a conflict between reality and your feeling of what reality "ought to be."
The Feynman Lectures on Physics (1964)
The answer is simple: because we can solve them!
The Feynman Lectures on Physics (1964)
It is important to realize that in physics today, we have no knowledge what energy is. We do not have a picture that energy comes in little blobs of a definite amount. It is not that way.
The Feynman Lectures on Physics (1964)
From a long view of the history of mankind — seen from, say, ten thousand years from now — there can be little doubt that the most significant event of the 19th century will be judged as Maxwell's discovery of the laws of electrodynamics.
The Feynman Lectures on Physics (1964)
If an apple is magnified to the size of the earth, then the atoms in the apple are approximately the size of the original apple.
The Feynman Lectures on Physics (1964)
If our small minds, for some convenience, divide this glass of wine, this universe, into parts — physics, biology, geology, astronomy, psychology, and so on — remember that nature does not know it!
The Feynman Lectures on Physics (1964)
Perhaps you will not only have some appreciation of this culture; it is even possible that you may want to join in the greatest adventure that the human mind has ever begun.
The Feynman Lectures on Physics (1964)
So far as we know, all the fundamental laws of physics, like Newton's equations, are reversible.
The Feynman Lectures on Physics (1964)
I hope ... that you will find someday that, after all, it isn't as horrible as it looks.
The Feynman Lectures on Physics (1964)
The same equations have the same solutions
The Feynman Lectures on Physics (1964)
Another way to remember their size is this: if an apple is magnified to the size of the earth, then the atoms in the apple are approximately the size of the original apple.
The Feynman Lectures on Physics (1963)
Whenever you see a sweeping statement that a tremendous amount can come from a very small number of assumptions, you always find that it is false. There are usually a large number of implied assumptions that are far from obvious if you think about them sufficiently carefully.
The Feynman Lectures on Physics (1964)
In fact, the science of thermodynamics began with an analysis, by the great engineer Sadi Carnot, of the problem of how to build the best and most efficient engine, and this constitutes one of the few famous cases in which engineering has contributed to fundamental physical theory. Another example that comes to mind is the more recent analysis of information theory by Claude Shannon. These two analyses, incidentally, turn out to be closely related.
