Black and white photo of Carl Anderson working on his cloud chamber. A large wire coil is probably an electromagnet used to deflect charged particles. Anderson has short dark hair with a receding hairline, and wears a dark gray suit despite being at work in the lab. He cuts a pretty dashing figure.

Physicist Carl Anderson was born #OTD in 1905.
Anderson developed an improved cloud chamber that he used to identify the positron – the antiparticle of the electron first theorized by Dirac.
Nowadays we use these particles for positron emission tomography (PET), android brains, and ghost busting.
