Well, you put it in something like a baby bottle, the components of which are shown here: You have a hard plastic bottle, a soft silicone nipple, and a hard plastic ring that… Continue reading A Stainless Steel Baby Bottle

Remembering the giddy futurism of Omni magazine. – By Paul Collins – Slate Magazine “The magazine was a lushly airbrushed, sans-serif, and silver-paged vision dreamed up by Penthouse publisher Bob Guccione and his wife, Kathy Keeton. It split the difference between the consumerist Popular Science–which always seemed to cover hypersonic travel and AMC carburetors in… Continue reading Links for 2010-01-04
Tiny Bubbles
OK, they’re not that tiny. Here’s your cute baby video for the weekend: Kate blowing bubbles for SteelyKid and Emmy: I really don’t need to say any more than that, do I?
Finding Patterns in Data: Fourier Series
Over at Faraday’s Cage, Cherish has a very nice post on Fourier series, following on an earlier post on Fourier transforms in the Transformers movie. She gives a nice definition of the process in the earlier post: A Fourier Transform takes a signal and looks at the waves and then shows us the frequencies of… Continue reading Finding Patterns in Data: Fourier Series

How to Teach Psychics Physics to Your Dog
In talking to a reporter about How to Teach Physics to Your Dog on Wednesday, I learned of a mistake in the text of the book– a footnote on page 71 says that Scientific American published an article on how to make your own “quantum eraser” in April 2007, when in fact it was May… Continue reading How to Teach Psychics Physics to Your Dog
The Problem With Urban Fantasy: I Want The Ponder Stibbons Story
Most of my fiction reading at the moment is done while rocking SteelyKid to sleep at night, using a Palm as an e-book reader. This does not really lend itself to the reading of weighty Literary Novels, but rather lightweight genre trash. Which means I’ve been reading a bunch of “urban fantasy,” because that is… Continue reading The Problem With Urban Fantasy: I Want The Ponder Stibbons Story
