At TED2010, mathematics legend Benoit Mandelbrot develops a theme he first discussed at TED in 1984 -- the extreme complexity of roughness, and the way that fractal math can find order within patterns that seem unknowably complicated.

The endoplasmic reticulum is one important organelle in the cell responsible for many things including protein folding. In this video, we will cover its structure and function of the rough endoplasmic reticulum and smooth endoplasmic...

The video discusses experiments that investigate how the emission and absorption of infrared radiation depend on the nature of the surface. The experiments involve using copper beakers with different painted surfaces and measuring the...

Depending on a type of tree and its age bark is rough or smooth. Boys were interested in running their fingers over tree’s trunk to feel the texture of its bark. So we made a portfolio of bark rubbings to take our discoveries home.

Experience different textures with this story.
