# Probably Science

Probably Science is a weekly comedy and science podcast which first aired on January 21, 2012. The show is co-hosted by Andy Wood, Matt Kirshen, and Jesse Case. Former co-host and founding member Brooks Wheelan left the show in 2013 for personal reasons and has since returned as a guest. In Brooks' absence, Case, previously a guest, was brought on as a co-host.
The podcast focuses on current scientific news. Occasionally it explores different facets of relevant media, including the host's comedy careers, as well as the large array of careers and hobbies held by the guests.
A wide range of guest have appeared in their episodes, including astronaut Chris Hadfield, astrophysicist Neil deGrasse Tyson, comedian Chris Hardwick, Sean M. Carroll (a research professor in the Department of Physics at the California Institute of Technology), and two appearances from Doctor Who and Guardians of the Galaxy actress Karen Gillan.

## SPATS

In episode 514, released on Nov. 27th, 2023, the podcast team introduced the SPATS. The concept is similar to the EGOT and is an honor for actors who have operated or traveled on a ship, plane, automobile, train, and spaceship in their films.
