I’m trying to inspire my students to enjoy and understand mathematics, but instead I seem to be their artistical muse.
One of my students drew this on the back of her test:
I was talking about why scientists sometime leave square roots in this form: 2√3 instead of calculating it out in decimal form and rounding it off to 3.5. The idea being that if you are sending a rocket to Mars and doing thousands of calculations, all those rounding-offs would cause a huge margin of error, and you could end up missing Mars by hundreds of thousands of miles.
At least he was paying attention to the lesson.
