"The fun part is this. We have a rule against machines... because the entropy tends to a maximum. ...Entropy is a measure of the scrambledness of the energy... and it's easier to scramble an egg than to unscramble it. ...So the rule is that entropy, the scrambledness of the energy tends to go up, and does not tend to go down, and for that reason you can't have a perpetual motion machine that takes energy in a more scrambled state and runs it out in a less scrambled state. It always goes the other way. It gets it in a less scrambled state and dumps it out scrambled."

John Dobson (amateur astronomer)
John Lowry Dobson (14 September 1915 – 15 January 2014) was an American amateur astronomer and is best known for the Dobsonian telescope, a portable, low-cost Newtonian reflector telescope. He was also known for his efforts to promote awareness of astronomy (and his unorthodox views of physical cosmology) through public lectures including his performances of "sidewalk astronomy". Dobson was also the co-founder of the amateur astronomical group, the San Francisco Sidewalk Astronomers.
