Speed Limit, Acceleration Limit, Speed Required
Road signs for mathematicians: a speed limit, then an acceleration limit, then a sign requiring speed to exist at all, with a fine for driving a nondifferentiable path.
Transcript
Road signs: "SPEED LIMIT 25 miles per hour" · "ACCELERATION LIMIT 25 miles per min²" · "SPEED REQUIRED" [a no-symbol over a jagged, cornered path] "nondifferentiability subject to fine"
