Trace the strange history of Graham crackers, invented by minister Sylvester Graham in order to curb the vices of Americans.

--

In the 1800s, minister Sylvester Graham believed Americans had a big problem— not just with their bodies, but their souls. He argued that overindulgence was fueling their baser desires, making them immoral and oversexed. To curb this corruption, puritanical reformers advocated for foods they thought curbed a variety of appetites. Stephanie Honchell Smith details the invention of Graham crackers.

Lesson by Stephanie Honchell Smith, directed by Anton Bogaty.

The ubiquitous yin-yang symbol holds its roots in Taoism/Daoism, a Chinese religion and philosophy. The yin, the dark swirl, is associated with shadows, femininity, and the trough of a wave; the yang, the light swirl, represents brightness, passion and growth. John Bellaimey explains why we all contain the spirit of yin and of yang -- and how we can achieve a balance of both in our lives.

MIT researcher Deb Roy wanted to understand how his infant son learned language -- so he wired up his house with video cameras to catch every moment (with exceptions) of his son's life, then parsed 90,000 hours of home video to watch "gaaaa" slowly turn into "water." This astonishing, data-rich research has deep implications for how we learn.

Puzzle through an ethical dilemma and decide: what responsibility do we have to honor the wishes of the dead?

--

For decades, Yvonne and Zaina have been happily married and co-leading a non-profit. One day the couple is involved in a car accident, and on her deathbed, Yvonne asks Zaina to promise her two things. First, to continue financially supporting their non-profit. And second, to never remarry. Should Zaina be beholden to these promises? Sarah Stroud and Michael Vazquez explore this ethical dilemma.

Lesson by Sarah Stroud and Michael Vazquez, directed by Prashanti Aswani.
