This realm is right under our noses, but from our perspective, the tiny specks of brilliant color blend together into a nondescript grey. What are these colorful microscopic particles? Michael Marder explores the science of dust. Lesson by Michael Marder, animation by Mette Ilene Holmriis. Thank you so much to our patrons for your support!

View full lesson: http://ed.ted.com/lessons/the-science-of-symmetry-colm-kelleher When you hear the word symmetry, you might think generally of triangles, butterflies, or even ballerinas. But defined scientifically, symmetry is "a transformation that leaves an object unchanged." Huh? Colm Kelleher unpacks this abstract term and explains how animal's distinct symmetries can tell us more about them -- and ourselves. Lesson by Colm Kelleher, animation by Andrew Foerster.
