5min 21sec @TEDEd clip - A brief #history of #toilets - Francis de los Reyes

found via a boingboing email 

Text from youtube "Explore the history of the toilet and how waste management has evolved from from ancient Mesopotamia to modern day.

On sunny days, citizens of ancient Rome could be found exchanging news and gossip while attending to more urgent business at the public latrines. Today, most cultures consider trips to the restroom to be a more private occasion. But even when going alone, our shared sewage infrastructure is one of the most pivotal inventions in human history. Francis de los Reyes shares the history of the toilet.

5min 30sec @TEDEd clip - #Newton’s three-body problem explained - Fabio Pacucci



text from youtube "In 2009, researchers ran a simple experiment. They took everything we know about our solar system and calculated where every planet would be up to 5 billion years in the future. They ran over 2,000 simulations, and the astonishing variety in results revealed that our solar system may be much less stable than it seems. Fabio Pacucci explores the n-body problem and the motion of gravitating objects.

5min @TEDEd clip - How do our #brains process speech? - Gareth Gaskell



Text from youtube "The average 20-year-old knows between 27,000 and 52,000 different words. Spoken out loud, most of these words last less than a second. With every word, the brain has a quick decision to make: which of those thousands of options matches the signal? And about 98% of the time, the brain chooses the correct word. How is this possible? Gareth Gaskell digs into the complexities of speech comprehension.

5min 33sec @TEDEd clip - What makes volcanoes erupt? - Steven Anderson



text from youtube "Dig into the science of how new volcanoes form, and what causes their unpredictable eruptions.

In February of 1942, Mexican farmer Dionisio Pulido thought he heard thunder coming from his cornfield. However, the sound wasn’t coming from the sky. The source was a large, smoking crack emitting gas and ejecting rocks, and would come to be known as the volcano Paricutin. Where do new volcanoes like this come from, and what triggers their unpredictable eruption? Steven Anderson investigates.

5min 18sec @TEDEd clip - What do all #languages have in common? - Cameron Morin



text from youtube "Dig into Noam Chomsky’s theory of universal grammar and decide: are there universal grammar rules and are they hardwired into our brains?


Language is endlessly variable. Each of us can come up with an infinite number of sentences in our native language, and we’re able to do so from an early age— almost as soon as we start to communicate in sentences. How is this possible? In the early 1950s, Noam Chomsky proposed a theory that the key to this versatility was grammar. Cameron Morin details Chomsky's theory of universal grammar.

8min 21sec @TEDEd clip - What causes #opioid addiction, and why is it so tough to combat? - Mike Davis



text from youtube "Explore the science of why opioids are addictive and what can be done to reverse the growing rates of addiction and overdose. If you or someone you know is struggling with opioid use in the United States, the Department of Health and Human Services operates a helpline (800-662-4357) and has a database of treatment facilities: https://www.hhs.gov/opioids/

In the 1980s and 90s, pharmaceutical companies began to market opioid painkillers aggressively, while actively downplaying their addictive potential. The number of prescriptions skyrocketed, and so did cases of addiction, beginning a crisis that continues today. What makes opioids so addictive? Mike Davis explains what we can do to reverse the skyrocketing rates of addiction and overdose.

6min 9sec @TEDEd clip - The dark history of #IQtests - Stefan C. Dombrowski



text from youtube "Explore the history of IQ tests; how they measure a person’s intelligence and the ways they have been used to justify scientifically baseless ideologies.
In 1905, psychologists Alfred Binet and Théodore Simon designed a test for children who were struggling in school in France. Designed to determine which children required individualized attention, their method formed the basis of the modern IQ test. So how do IQ tests work, and are they a true reflection of intelligence? Stefan C. Dombrowski explores how the tests have been used throughout history. Lesson by Stefan C. Dombrowski, directed by Kozmonot Animation Studios. Animator's website: https://www.kozmonot.tv/
