Explore how economic inequality can be measured and how it is impacted by different governmental policy choices.

--

Income and wealth inequality are not new. In fact, economists and historians who have charted economic inequality throughout history haven’t found a single society without it. Which raises a bleak question: is inequality … inevitable? Explore how economic inequality can be measured and how it is impacted by different governmental policy choices.

Directed by Natália Azevedo Andrade, AIM Creative Studios.

Trace the 7,000 year old history of alcohol, from its first known origins in China to cultures all over the world fermenting their own drinks.

Uploaded 02-01-20

--

Nobody knows exactly when humans began to create fermented beverages. The earliest known evidence comes from 7,000 BCE in China, where residue in clay pots has revealed that people were making an alcoholic beverage from fermented rice, millet, grapes, and honey. So how did alcohol come to fuel global trade and exploration? Rod Phillips explores the evolution of alcohol.

Taylor Wilson believes nuclear fusion is a solution to our future energy needs, and that kids can change the world. And he knows something about both of those: When he was 14, he built a working fusion reactor in his parents' garage. Now 17, he takes the TED stage at short notice to tell (the short version of) his story.

Dig into the Romeo and Juliet Effect, which describes the tendency to find someone more desirable when met by parental opposition.

--

In 1972, psychologists at the University of Colorado surveyed 140 couples to determine whether a relationship facing parental disapproval was more likely to strengthen or crumble under the pressure. Can long-term success of a romantic relationship be predicted by the perceived approval or disapproval of the couple’s friends and family? Dig into the trend known as the Romeo and Juliet Effect.

The US consumes 25% of the world's oil -- but as energy tycoon T. Boone Pickens points out onstage, the country has no energy policy to prepare for the inevitable. Is alternative energy our bridge to an oil-free future? After losing $150 million investing in wind energy, Pickens suggests it isn't, not yet. What might get us there? Natural gas. After the talk, watch for a lively Q and A with TED Curator Chris Anderson.

A decade ago, Robin Chase founded Zipcar in the US, now the largest car-sharing company in the world. Now she's exploring the next level of car-sharing: Buzzcar, a French startup that lets people rent their own cars to others. The details are fascinating (how does insurance work, exactly?), and the larger vision (she calls it Peers, Inc.) points to a new definition of ownership and entrepreneurship.
