In early 1961 a new president, John F. Kennedy, was told by military leaders and civilian officials that the Kingdom of Laos - of no conceivable strategic importance to the U.S. - required the presence of American troops and perhaps even tactical nuclear weapons. Why? Because if Laos fell, Asia would go red from Thailand to Indonesia.

The fact that you can remember yesterday but not tomorrow is because of entropy. The fact that you're always born young and then you grow older, and not the other way around like Benjamin Button - it's all because of entropy. So I think that entropy is underappreciated as something that has a crucial role in how we go through life.
