Johnny Galecki

Johnny Galecki — Well, if you are a huge fan of science (or just a huge fan of good TV), then you probably already know all about this actor. But, if quantum physics happens to not necessarily be a forte of yours, or if you happen to be a little behind on your shows, then don’t you worry, because we are here to catch you all up to speed!

Galecki has been in the entertainment industry for quite a few years now, but it perhaps wasn’t until 2006 that he really made a big “bang” in the industry. That year was when he landed his iconic lead role on The Big Bang Theory. He was cast as Leonard Hofstadter, a brilliant physicist working at Cal Tech and living in Pasadena, California with his equally brilliant (and socially awkward) friends.

Before anyone knew it, the CBS show became an instant fan-favorite, and so did the very talented Galecki!
