Your greatest creation is yourself. Like any great work of art, creating a great self means putting in hard work, every day, for years.

The always-brilliant Vi Hart teaches you math via mashed potatoes. For more irreverent and playful math education, see Paul Lockhart’s Measurement

Vi Hart is back with another jaw-dropping hexaflexagon demo, following up on the first one – who knew paper could hold so much mathematical whimsy?

( It’s Okay To Be Smart)

Once again, mathemusician Vi Hart makes math enormously fun with these collapsible paper hexagons. Also see Paul Lockhart’s Measurement, a journey into the whimsy of mathematical reality.

Mathemusician Vi Hart is back with anti-parabola propaganda and some musing on math class, cardioids, connect the dots, envelopes of lines, even a bit of origami. Also see Hart’s Fibonacci numbers explained in stop-motion vegetables, the Victorian novella Flatland on a Möbius strip, and the science of sound, frequency, and pitch in stop-motion doodles.
