Nerd Nite SF #118: Low-Brow Botany, Ghost Signs, and Cat VR

*All attendees must be fully vaccinated and be able to show proof. Let's keep everyone safe and sound during this return to live entertainment!*. Nerd Nite SF is a monthly lecture-in-a-bar series where we invite interesting people - scientists, historians, game designers, mimes, etc. - to give short talks on their expertise to tipsy nerds. We strive to be playful, entertaining, sometimes a little inebriated or salacious, but always deeply educational. Join us!https://sf.nerdnite.com/
