This week, we're looking back at four remarkable minds whose weekly meetings set the stage for a revolution in science and technology. We're joined by science historian Laura J. Snyder, to talk about her book "The Philosophical Breakfast Club: Four Remarkable Friends who Transformed Science and Changed the World." And we'll speak to "Surly" Amy Davis Roth and Skepchick contributor Melanie Mallon, about the science track at CONvergence 2014.
