  • Why aren’t commercial flights getting faster? Dig into the technological and environmental problems facing supersonic flight. --In 1996, a British Airways plane flew from New York to London in a record-breaking two hours and fifty-three minutes. Today, however, passengers flying the same route can expect to spend no less than six hours in the air — twice as long. So why, in a world where everything seems to be getting faster, have commercial flights lagged behind? Alex Gendler details the problems facing supersonic flight.Lesson by Alex Gendler, directed by Zedem Media.Support Our Non-Profit Mission----------------------------------------------Support us on Patreon: http://bit.ly/TEDEdPatreonCheck out our merch: http://bit.ly/TEDEDShop----------------------------------------------Connect With Us----------------------------------------------Sign up for our newsletter: http://bit.ly/TEDEdNewsletterFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagram----------------------------------------------Keep Learning----------------------------------------------View full lesson: https://ed.ted.com/lessons/why-are-airplanes-slower-than-they-used-to-be-alex-gendlerDig deeper with additional resources: https://ed.ted.com/lessons/why-are-airplanes-slower-than-they-used-to-be-alex-gendler#digdeeperAnimator's website: https://www.zedemanimations.com/----------------------------------------------Thank you so much to our patrons for your support!

  • For some reason, says educator Al Vernacchio, the metaphors for talking about sex in the US all come from baseball -- scoring, getting to first base, etc. The problem is, this frames sex as a competition, with a winner and a loser. Instead, he suggests a new metaphor, one that's more about shared pleasure, discussion and agreement, fulfillment and enjoyment. Let's talk about ... pizza. Talk by Al Vernacchio.
