““Thermodynamics is a funny

subject. The first time you go

through it, you don't understand it at

all. The second time you go through

it, you think you understand it,

except for one or two small points.

The third time you go through it, you

know you don't understand it, but by

that time you are so used to it, it

doesn't bother you anymore.”
