Scientists achieve optical measurements at atomic scales using quantum electron tunneling, surpassing conventional microscopy limits by nearly 100,000 times with standard lasers.

Researchers at the University of Cambridge and Meta Reality Labs have, for the first tim,e mapped the resolution limits of human vision. In other words, they calculated how many pixels we can truly ...

It’s been a long-held assumption that the human eye is capable of detecting a maximum of 60 pixels per degree (PPD), which is commonly called ‘retinal’ resolution. Any more than that, and you’d be ...
