Quadratic equations, lots of them, scrawled out with the tentativeness of an adolescent's hand.
I'll rake for clams this weekend, fish for striped bass, then bumble in the still chilly garden for a bit.
Which means reading tide charts, currents, and dirt.
I can't tell you how many times I got hit with quadratic equations, electromotive force charts, trig tables, and that freaking pickle jar in Ethan Frome way back in high school.
Then I'd go home and go fishing.
Not saying school wasn't useful--I may still have a decade or two to stumble upon a situation where I might need to decipher broken pickle dishes--but I learned a lot more useful stuff staring at the surf than I ever learned in school.
1:1 computers doesn't change this.
