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.
haptic doom
Jokes on him, I can already tell the difference between a house and a car
Houses are the ones with doors and glass on some of the outside, right?
No, those are cars, you’re thinking about the ones with A/C and mirrors.

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.

most of that is what she said
But you can feel that the texture is somehow different.
It’s not that you can feel individual features, but rather that a repeating pattern of that size can be distinguished from a smoother surface.
that website fuckin sucks
but yes very cool
Why’s that?
when you try to back into the previous tab it redirects to the websites main page, which is also filled with clickbait ads and garbage
Yes, right, but not on a screen.
Yet numerous people can’t find the clitoris. It’s baffling.
