Adam Explains Möbius Strips and Klein Bottles!

Adam dives into the awesomeness of the Klein bottle–a classic physical example of a non-oreintable surface (eg. a one-sided surface akin to a Mobius strip). Adam’s Klein bottle was made by one of his heroes, computer scientist Cliff Stoll–one of the first people to uncover espionage through connected computer systems. This Show and Tell becomes as much a celebration of fourth-dimensional objects as it is the career and story of Cliff Stoll, who Adam hopes to collaborate with one day!

You can find Cliff Stoll’s klein bottles at www.kleinbottle.com, Cliff Stoll’s book The Cuckoo’s Egg, NOVA episode “The KGB, The Computer, and Me”, Numberphile’s episode on Cliff Stoll. Disclaimer: Tested may earn an affiliate commission when you buy through the links here.
