What are people saying about Ask a Scientist?

"Ask a Scientist is one of my favorite discoveries in San Francisco.  It never fails to deliver a fun and fascinating evening of cutting edge discovery with a world-class scientist. Keep up the excellent job!"
David Fitzgerald, Author

"Ask a Scientist is the best thing since the discovery of fire! To make contact with great minds in an intimate setting is something that might cost a fortune, but Ask a Scientist and the Bay Area's generous scientific community provide it for free. I feed my mind and my tummy as often as I can at Ask a Scientist."
Tucker Hiatt,
Director of Wonderfest

"The speakers are brilliant and articulate and the science is presented in an accessible way.  The questions, too, are on a very high level, and the result is an evening of reliably and enjoyably intelligent discourse I have not found matched anywhere else."
David F. Phillips

"Ask a Scientist is an amazing way to learn about cutting edge science. It's inspiring and unpretentious!"
Alanna Zrimsek,
Winston Gallery, SF

"Thanks to Ask a Scientist, I am now Master of Time, Space and Dimension. AND I'm getting twice as many dates!"
Curtis Lim
