Quotes about Uncertainty

You cannot predict the future.

There is no way that we can predict the weather six months ahead beyond giving the seasonal average

Science seems to have uncovered a set of laws that, within the limits set by the uncertainty principle, tell us how the universe will develop with time, if we know its state at any one time.

The guilty man may escape, but he cannot be sure of doing so.

Luther always maintained that he was probably born in 1484, but neither Luther nor even his own mother could be sure, and current reckoning puts it more likely at either 1482 or 1483, with the preponderance of evidence favoring the latter, so that in the course of this book we shall use that year.
