A Look at our Sense of Touch

Prim­al, Acute and Eas­ily Duped: Our Sense of Touch is a recent art­icle from Pulitzer Prize-win­ning Nat­alie Angi­er (author of The Can­on: The Beau­ti­ful Basics of Sci­ence) tak­ing a rudi­ment­ary look at the sense of touch and some recent research in the field of haptics.

Sci­ent­ists have determ­ined that the human fin­ger is so sens­it­ive it can detect a sur­face bump just one micron high […] 1/25,000th of an inch — the dia­met­er of a bac­teri­al cell.

Aside from the fas­cin­at­ing accur­acy of the sense, the art­icle looks briefly at what is dubbed the ‘rub­ber hand illu­sion’ which Mind Hacks looks at in more detail—and I sug­gest you do too.
