Well, sometimes it was. It was also the result of hard work, teamwork, and competition. And incredibly surprising moments. Hosted by bestselling author Steven Johnson (“How We Got To Now”), American Innovations uses immersive scenes to tell the stories of the scientists, engineers, and ordinary people behind the great ...

Flash Forward is a show about possible (and not so possible) future scenarios. What would the warranty on a sex robot look like? How would diplomacy work if we couldn’t lie? Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...

Stephen Fry's 7 Deady Sins - I will take each one of the Seven Sins in turn, lay them out on the surgical table and poke, prod, pry and provoke in an attempt to try to anatomise and understand them; I hope and believe it will be, if nothing else, delicious fun and something of a change from the usual run of podcastery. Hosted on Acast. See acast.com/privacy for more information.

Our history of LEDs continues with the entry of LEDs into commercial lighting. We talk of different ways to get white light out of LEDs, and materials for white-light LEDs. We briefly discuss color temperature because there are different kinds of white. Then we hear of the publication of an article in 2000 that consolidated thinking about home usage for LEDs, and why LEDs have advantages over other lamps. We mention ways geometrically to optimize LED construction to maximize the amount of light emitted. Finally, we note the development of second-generation emitting compounds in red, green, and blue that pushed LEDs over the finish line to make them practical for home usage.
