Local Science Lecture Series

Ask A Scientist

An informative, entertaining, monthly lecture series, held at a San Francisco cafe. Each event features a speaker on a scientific topic, a short presentation, and the opportunity to ask all those burning questions that have been keeping you up at night. No tests, grades, or pressure…just food, drinks, socializing, and conversation about the universe’s most fascinating mysteries!

Down To A Science

Bringing scientific discussion to a hungry public. It’s a casual environment where scientists mingle with the like-minded in a forum for exploring new ideas, discussing new concepts and expanding personal horizons. Down to a Science encourages open, easy-to-understand conversation. Translation: No lectures. No technical jargon. Just food, drinks, and science!
