Matthew Francis

I’m a physicist, science writer, public speaker, educator, and frequent wearer of jaunty hats . My writing and speaking specialties are cosmology, astronomy, and many other subjects in physics, all aimed at non-specialist audiences. As director of CosmoAcademy, I teach and organize classes on astronomy and related topics. I blog about science, science communication, education, and culture at Galileo’s Pendulum. I have even appeared in comics form as Pluto’s moon Nix.
