We have a special guest on the show today! This one was very fun to record. Martin Pfeiffer, perhaps more notorious by his Twitter handle @NuclearAnthro, is a must-follow expert and Anthropology PhD student who studies the history of nuclear weapons, and how human societies interact with them. We discuss folk beliefs about nuclear weapons, the history of the individuals who've wielded them... and just how easy it is for the President to launch a nuclear strike.  We built them. We can take them apart. You can find Martin's Twitter @NuclearAnthro, and his blog is below: https://deusexatomica.wordpress.com/ If you enjoy his work (and you really should), you can find links to a Paypal and Patreon on both. You can find Physical Attraction at www.physicspodcast.com, where you'll also find ways to support our show, and a contact form for comments, praise, concerns, abuse, and questions as well as suggestions for future show topics. We read it all.
