Just about everyone who’s ever built a computer has seen a bare hard drive, but thanks to an electron microscope, we can now get a fascinating up-close look at the read / write head. That is just one of the many everyday things viewed under an electron microscope that we’ve rounded up for you today. Continue reading to see them all.

An electron microscope (EM) is a type of microscope that uses an electron beam to illuminate a specimen and produce a magnified image. An EM has greater resolving power than a light microscope and can reveal the structure of smaller objects because electrons have wavelengths about 100,000 times shorter than visible light photons. They can achieve better than 50 pm resolution and magnifications of up to about 10,000,000x whereas ordinary, non-confocal light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000x.
