haptic doom

The human finger can discriminate between surfaces patterned with ridges as small as 13 nanometers in amplitude and non-patterned surfaces, surface chemistry Professor Mark Rutland said. "This means that, if your finger was the size of the Earth, you could feel the difference between houses [and] cars," Rutland said.

In practice I find that anything smaller than .0001 inches can't really be felt, and the difference between .0001 and .0002 is indiscernible.

13 nanometers is closer to .0000005 inches.

But you can feel that the texture is somehow different.
