The computer animation Outside In explains the amazing discovery, made by Steve Smale in 1957, that a sphere can be turned inside out by means of smooth motions and self-intersections. Through a combination of dialogue and exposition accessible to anyone who has some interest in mathematics, Outside In builds up to the grand finale: Bill Thurston's "corrugations" method of turning the sphere inside out.

[…] Though the highs and lows of human experience are all here, it's often the gimcrack set design and fashion chops in these vintage clunkers that really wow – the pot-holder sweater vests, ponytails decorated with yarn, hippies with crumb-catching moustaches, banana-seat bikes and a hard rain of Quaaludes and amphetamines to illustrate the dangers of drug addiction. It is hard to believe anyone would buy the goofball cause-and-effect of that pill-popper's weather pattern in "Drugs Are Like That". Co-produced by the Miami Junior League and narrated by Anita Bryant in this cheery little hand-slapper, a kid stealing cookies from a cookie jar is implied to be headed down a bad road to Bowery bum rolls and LSD parties.

NOVA leads viewers on a mathematical mystery tour -- a provocative exploration of math's astonishing power across the centuries. We discover math's signature in the swirl of a nautilus shell, the whirlpool of a galaxy and the spiral in the center of a sunflower. Math was essential to everything from the first wireless radio transmissions to the prediction and discovery of the Higgs boson and the successful landing of rovers on Mars. But where does math get its power? Astrophysicist and writer Mario Livio, along with a colorful cast of mathematicians, physicists and engineers, follows math from Pythagoras to Einstein and beyond, all leading to the ultimate riddle: Is math an invention or a discovery? Humankind's clever trick or the language of the universe?

A newly re-discovered classic, The Underseas Explorers is an animated educational cartoon that was first shown in 1961. A true collectors item, it has been proclaimed to be "ahead of its time." Owing to its inclusion of an "island boy" character similar to "Hadji," it has sometimes been referred to as an underwater version of "Johnny Quest." Onboard the tiny atomic submarine "Hydronaut," a small group of underwater adventurers set out to explore the oceans and circumnavigate the globe under the North Pole (the Arctic Cap). During their televised journey, they discover the original landing site of old pirates. Professor Scott meets undersea creatures including an unexpected underwater duel with an eight-legged octopus. The title has often been incorrectly referred to as: The Undersea Explorers, The Underwater Explorers, The Underwater Adventurers, Journey to the Bottom of the Sea and many others.
