I doubt that this will actually work, but then the Web has brought me some improbable successes before, so it’s worth a shot: I have a sealed glass cell (Pyrex, I think, if it matters) that I would like to get re-filled with a mix of rare gases– partial pressures of 100mT Ne, 30mT Ar,… Continue reading Technical Request: Gas Cell Filling

Simple Answers to Complex Medical Questions
There’s a new medical study of the effects of alcohol consumption that finds a surprising result: Controlling only for age and gender, compared to moderate drinkers, abstainers had a more than 2 times increased mortality risk, heavy drinkers had 70% increased risk, and light drinkers had 23% increased risk. A model controlling for former problem… Continue reading Simple Answers to Complex Medical Questions

This is why I “support” majoritarian rule. – Acephalous “As a means of registering my discontent with conservative claims that the fact that 70 percent of Americans abhor the idea of the “Ground Zero Mosque” means it should be abandoned, I hereby present other things that 70 percent of “certain” Americans once hated.” (tags: politics… Continue reading Links for 2010-09-01
Without Experiment, There Is No Theory
A lot of people have been blogging and Twittering about this subway map of science, which puts various branches of science in the place of the lines on the London Underground map, showing connections between them. It’s a huge graphic, but a kind of cool image. I do, however, have a problem with it, which… Continue reading Without Experiment, There Is No Theory
Backyard Fluid Dynamics Revisited
Back in July, I did a post looking at how the fountain in our ornamental backyard pond shoots higher when the level of the pond drops. I set up a simple model of the process, which worked surprisingly well, but I said at the time that I really needed more data to say whether that… Continue reading Backyard Fluid Dynamics Revisited
Why So Many Blogging Astronomers?
Over in Discover-land, Razib has a couple of posts about the content of science blogs, based on an analysis of the content of the top science blogs according to Wikio. Razib’s second post is sparked by a pointed question from the author of the original study: I’m now curious to find out why there are… Continue reading Why So Many Blogging Astronomers?
Bad Universe, No Biscuit
Sunday was a really long day around Chateau Steelypips, and I couldn’t see staying awake to watch the premiere of Phil Plait’s Bad Universe on the Discovery Channel, so I’m way late in writing about it. I DVRed it, though, and watched it last night. The theme of the premiere/ pilot was killer rocks from… Continue reading Bad Universe, No Biscuit

slacktivist: The Clod and the Pebble and the politics of resentment “What happened was that 78 poor children whose fathers are incarcerated received free back-to-school supplies provided by three area churches. Their dads were permitted to be on hand to help present these presents, getting a rare chance to spend a few hours with their… Continue reading Links for 2010-08-31
Indirect Excitation Control: Ultrafast Quantum Gates for Single Atomic Qubits
Last week, John Baez posted a report on a seminar by Dzimitry Matsukevich on ion trap quantum information issues. In the middle of this, he writes: Once our molecular ions are cold, how can we get them into specific desired states? Use a mode locked pulsed laser to drive stimulated Raman transitions. Huh? As far… Continue reading Indirect Excitation Control: Ultrafast Quantum Gates for Single Atomic Qubits
Nobody Ever Remembers Being a Cow
There was a deeply silly New York Times article about “Past Life Regression” over the weekend: In one of his past lives, Dr. Paul DeBell believes, he was a caveman. The gray-haired Cornell-trained psychiatrist has a gentle, serious manner, and his appearance, together with the generic shrink décor of his office — leather couch, granite-topped… Continue reading Nobody Ever Remembers Being a Cow
