Perpetual Motion Machines / The endless quest for free energy MP3

Happy birthday to us: Incredible but true: Interesting Thing of the Day is 10 years old! I distinctly remember learning the laws of thermodynamics in a science class—it must have been around eighth grade. After explaining these laws, the teacher added, “…and that is why perpetual motion machines are impossible.” So this fact has been firmly implanted in my brain for a very long time. What ...

    The Dvorak Keyboard Controversy / Chasing QWERTY MP3

    When I was first learning to type, many years ago, I asked the same question everyone else asks: why are the keys arranged so stupidly? Why aren’t they laid out in a more logical order, as in, just to take one random example, alphabetically? The answer I’ve heard countless times is that the first typewriter keyboards were arranged alphabetically, but that caused mechanical problems—once typists became reasonabl...

    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...

    Lightsabres / The myth and technology of the Jedi weapon MP3

    Like most people, I thoroughly enjoyed the three original Star Wars films, and like most people, I found the prequel installments rather disappointing. The special effects and visual quality were dramatically improved, but the stories left much to be desired, the acting was mediocre, and the writing had none of the intensity or sparkle of the originals. After “Episode I: The Phantom Menace” appeared, I wa...

    Tiki / The imaginary Polynesian culture MP3

    One day last summer I walked into one of my favorite mom-and-pop variety shops in San Francisco and saw a big display of everything Tiki—a Tiki bar, Tiki glasses, Tiki masks, Tiki statues, Tiki books. My initial reaction was, “Ah, another cheesy American fad is reborn,” followed quickly by, “Cool! I need to own this stuff.” What can I say? I’m a sucker for faux culture, especial...

    Benedictine Oblates / Becoming a modern monk MP3

    Guest Article by Sheri Hostetler Thanks to Kathleen Norris, being a Benedictine oblate is almost hip these days. Norris is the author of the critically received books Dakota: A Spiritual Geography and The Cloister Walk. Both tell the story of a literary New Yorker who moved to the Great Plains and found a spiritual life at—of all places—a Benedictine monastery. More than any other person since Thomas Me...
