Summary: Melanie Kiechle introduces us to the 19th-century world of smell detectives, where the nose reigned supreme and cities mapped their stench patterns; Sam Kean tells how gases can have a profound effect on us—from knocking us out to making us laugh, and even causing the French Revolution. Plus, top off our exploration into the sensory world of invisible forces with an excerpt from a new book on all the light we cannot see. <hr> <strong>Go beyond the episode:</strong> <ul class="MailOutline"> <li class="">Melanie Kiechle’s <i class=""><a class="" href="http://www.washington.edu/uwpress/search/books/KIESME.html">Smell Detectives</a>: An Olfactory History of Nineteenth-Century Urban America</i> </li> <li class="">Sam Kean’s <a class="" href="https://www.hachettebookgroup.com/titles/sam-kean/caesars-last-breath/9781478986058/"><i class="">Caesar’s Last Breath: Decoding the Secrets of the Air Around Us</i></a> </li> <li class="">Check out a modern-day <a class="" href="http://sensorymaps.com/portfolio/smellmap-paris/">smell map of the City of Light</a> (and Odor), from graphic designer Kate McClean</li> <li class="">Live in Pittsburgh?
