Flywheel Batteries / A new spin on energy storage MP3

Happy birthday to us: Incredible but true: Interesting Thing of the Day is 10 years old! A friend of mine recently installed solar panels on his roof to generate electricity. They were quite expensive, but my friend considers it an investment that will pay for itself in lower electricity bills over a period of decades. Of course, the panels generate electricity only when the sun is shining. The house is still conne... Source: itotd.com

    Planning Your Own Funeral / Having the last laugh first MP3

    When my mother returned from a vacation to Florida with her sister a number of months ago, I called to ask how it went. “Oh, we had the best time!” she said. “We spent most of the trip planning our funerals. It was hilarious!” Well, that wasn’t quite what I was expecting to hear. On previous vacations my mom has gone on cruises, even tried parasailing, and I thought I had a pretty good ...

    Starlite / The mystery miracle heatproof plastic MP3

    In the early 1990s, magazine articles and television shows in Great Britain and the United States ran a series of stories about an incredible new invention: a type of plastic that could withstand virtually any amount of heat. The material’s properties confounded scientists, but even more amazing was that its creator, Maurice Ward, had no academic credentials—he was, in fact, a former hairdresser from No...

    Crème Brûlée / Why every kitchen needs a blowtorch MP3

    The restaurants of America—especially those of the fast-food variety—have come under attack for, among other things, making portion sizes much too large. This, nutritionists say, is one of the main causes of obesity. But I think the biggest problem with large portions is that they make it that much harder for patrons to leave room for dessert. I believe deeply in dessert, and few things cause me as much...

  • Lichens / A tale of two organisms

    Lichens / A tale of two organisms MP3

    by Morgen Jahnke There are some things in the natural world I tend to take for granted, but that reveal true surprises when I look at them more closely. Such is the case with lichens. I’ve known about lichens since childhood, but it turns out I never really knew anything about them at all. I always assumed they were like mosses, vegetable-like things that grew on the ground, rocks, and trees. In fact, lichens...

    Helioseismology / Listening to the inside of the Sun MP3

    Although in general I have tremendous faith in science, there are a few concepts I’ve always had some trouble grasping. For example, textbooks have told us for decades—with great certainty—details about the interior of the Earth. We know how thick the crust and mantle are, what the core is made of, and how hot it is (among many other facts), even though no one has managed to dig or drill even hal...
