Comic #4770: geometry
Description
Here's the transcription of the comic text:
Panel 1: "Since the Babylonian days, mathematicians have wondered if it were possible to 'square the circle.' That is, using only a compass and straightedge, can you construct a square with the same area as a given circle."
Panel 2: "Mathematicians supposedly proved you couldn't back in 1882." "They were wrong."
Panel 3: "Imagine your compass and straightedge."
Panel 4: "First, put a pencil on one end of the compass and an eraser on the other."
Panel 5: "Second, you designate any number of tiny boxes on your straightedge. Using the compass, you can draw or erase symbols on the straightedge."
Panel 6: "And what's that called?" "A Turing machine."
Panel 7: "So, now we can rephrase the problem: using only a computer, can you construct a square with the same area as a given circle?"
Panel 8: "Using this general method, we can unlock all 'compass and straightedge' problems!"
Panel 9: "Are you missing the point accidentally or strategically?" "I'm mostly trying to make the philosophy students sad."
Feel free to ask if you need anything else!
