“Energy is liberated matter, matter is energy waiting to happen.”

“You may not feel outstandingly robust, but if you are an average-sized adult you will contain within your modest frame no less than 7 X 10^18 joules of potential energy—enough to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point. Everything has this kind of energy trapped within it. We're just not very good at getting it out. Even a uranium bomb—the most energetic thing we have produced yet—releases less than 1 percent of the energy it could release if only we were more cunning.”

“In three minutes, 98 percent of all the matter there is or will ever be has been produced. We have a universe”

“Strange as it may seem, wrote Richard Feynman, we understand the distribution of matter in the interior of the Sun far better than we understand the interior of the Earth.”

“The upshot of all this is that we live in a universe whose age we can't quite compute, surrounded by stars whose distances we don't altogether know, filled with matter we can't identify, operating in conformance with physical laws whose properties we don’t truly understand.”

“Take a moment from time to time to remember that you are alive. I know this sounds a trifle obvious, but it is amazing how little time we take to remark upon this singular and gratifying fact. By the most astounding stroke of luck an infinitesimal portion of all the matter in the universe came together to create you and for the tiniest moment in the great span of eternity you have the incomparable privilege to exist.”

“Because bread was so important, the laws governing its purity were strict and the punishment severe. A baker who cheated his customers could be fined £10 per loaf sold, or made to do a month's hard labor in prison. For a time, transportation to Australia was seriously considered for malfeasant bakers. This was a matter of real concern for bakers because every loaf of bread loses weight in baking through evaporation, so it is easy to blunder accidentally. For that reason, bakers sometimes provided a little extra- the famous baker's dozen.”
