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.

- 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.
- Photos of a PET (Positron Emission Tomography) scan of a human torso. Parts of the skeleton and organs are imaged, and two bright spots indicate something being targeted by the scan.
- The android Data from Star Trek: The Next Generation.
- Ghostbuster Egon Spengler unleashing a proton beam from the unlicensed positron collider he is wearing on his back. He is attempting to bust Gozer the Gozerian, Gozer the Destructor, Gozer the Traveler, Volguus Zildrohar and Lord of the Sebouillia.
