Physicist by day, journalist and musician by night – Dr. David Robert Grimes just may be the Dark Knight of Science, advocating for higher standards in media coverage and working out the physics behind your favorite guitar riffs.

This episode is all about no-holds-barred science activism, covering everything from the anti-vaxx movement, to fear of GMOs, and water fluoridation. Hold on to your hats, kids – it's going to be a bumpy ride.

Many thanks to David for donating some of his own original music for this episode. You can follow David on his blog, at the Guardian, or on Twitter. 

As always, our gratitude goes out to Billy and the kind people of New World Brewery for the fantastic selection of beer and food. If you're in Ybor, you have to stop by to say hello from 2Scientists.
