"/usr stands for UNIX System Resources"

And less technical:

"The rainbow has 7 colors"

"Sun is the day, moon is the night"

Love this Sussman quote: “ In fact, this is an engineering model, in the same way that, [for an] electrical resistor, we write down a model V = IR—it's approximately true, but it's not really true; if I put enough current through the resistor, it goes boom, so the voltage is not always proportional to the current, but for some purposes the model is appropriate”

This is only sensible for models that are useful for something.
