Happy Mole Day! No, no, no, not that kind of mole. This mole — a concept used in chemistry to count molecules, atoms, or anything super, super small. Because atoms and molecules are so tiny, scientists like to bundle them into groups to keep better track of them, and a mole is a group of 602 sextillion — or 6.02 x 10^23. Hence Mole Day, which started at 6:02 AM today, October 23 (10/23).
To learn more fun facts about moles, check out the TED-Ed lesson below:
And for more insight into the wonderful world of chemistry, check out these 3 great Mole Day-worthy TEDx Talks:
- Nanomaterials — the science of the small: Stefan Bon at TEDxWarwick:
Stefan Bon is a chemist who’s been doing some very interesting work, including halving the fat of chocolate by replacing the fat materials that bond chocolate together with an emulsion of fruit juice particles. Crazy stuff!
- The streetlamp that absorbs CO2: Pierre Calleja at TEDxLausanneChange
Biochemist Pierre Calleja has designed streetlamps powered with living algae. No, really
- Hey science teachers — make it fun! Tyler DeWitt at TEDxBeaconStreet
Ever fall asleep in chemistry class while staring at the periodic table? Well, science teacher Tyler DeWitt asks teachers to make science fun — with stories, demonstrations, and even cartoons.
Happy mole day! (:
