Description: Occam’s Razor is the scientific principle stating that all other things being equal, the simplest solution tends to be the best one. A great science geek gift for a scientist. The more assumptions you have to make, the more unlikely an explanation.

Description: Thomas Paine quote: It is never to be expected in a revolution that every man is to change his opinion at the same moment. There never yet was any truth or any principle so irresistibly obvious that all men believed it at once. Time and reason must cooperate with each other to the final establishment of any principle; and therefore those who may happen to be first convinced have not a right to persecute others, on whom conviction operates more slowly. The moral principle of revolutions is to instruct, not to destroy.

Description: If Heisenberg were more dramatic...he might have sounded more like this!

Description: Hermetic principle.

Description: Thomas Paine quote: A thing, moderately good, is not so good as it ought to be. Moderation in temper, is always a virtue; but moderation in principle, is a species of vice.
