Math Joke 2

Until last week I knew exactly 2 funny math jokes. Now I know three. I’ll post the third one tomorrow. Here’s the second one.

An engineer, a physicist, and a mathematician are asleep in a hotel when the curtains in each of their rooms catch fire. (Inexplicably, and all at the same time. Don’t ask why, it’s not important.)

The engineer wakes up and sees the fire, runs into the bathroom, fills the wastebasket with water, comes back and throws it on the fire. The fire goes out immediately, but there’s quite a bit of water damage.

The physicist wakes up and sees the fire, and pauses to estimate the rate at which the curtains are being consumed. He runs into the bathroom, fills the wastebasket with exactly 1.7 liters of water, comes back and carefully pours it on the fire. There’s a bit more fire and smoke damage due to the delay, but not a drop of water is spilled unnecessarily.

The mathematician wakes up and sees the fire, and pauses to contemplate the problem. Then he calmly walks into the bathroom. He turns on the faucet and strikes a match, then douses the match under the running water. He examines the match closely for a minute, then says, “Ah yes, this problem has a solution.” And then he goes back to bed.
