something i learned today:

the ratio between the size of one digit of one of your fingers and the next digit of the same finger is roughly Φ, the golden ratio. Their lengths line up in an approximate way with sequential fibonacci numbers, because as the fibonacci sequence progresses the ratio between sequential numbers approaches Φ.  i illustrated this in that image using an arbitrary unit of pixels and the grid in photoshop.

but the real cool part is that because of this, when you curl and uncurl your fingers, the path described by a fingertip is pretty close to a perfect golden spiral! what sweetly built machines we pilot over the earth

Graphing Rational Functions. Endless source of puns.

  • Student: What the hell ARE "holes", anyway? Why did we have to learn about them? What do they DO?
  • Teacher: They're holes. It just means the function isn't there.
  • Student: But... what does that mean?
  • Teacher: That's another whole discussion.
  • Me: That's another HOLE discussion!
  • -Entire class is silent except for teacher, who laughs-
