Phys. Rev. Lett. 105, 040504 (2010): Room-Temperature Implementation of the Deutsch-Jozsa Algorithm with a Single Electronic Spin in Diamond “The nitrogen-vacancy defect center (N-V center) is a promising candidate for quantum information processing due to the possibility of coherent manipulation of individual spins in the absence of the cryogenic requirement. We report a room-temperature implementation… Continue reading Links for 2010-07-24
Dinosaurs Are Too Easy
Earlier this week, there was some interesting discussion of science communication in the UK branch of the science blogosphere. I found it via Alun Salt’s “Moving beyond the ‘One-dinosaur-fits-all’ model of science communication” which is too good a phrase not to quote, and he spun off two posts from Alice Bell, at the Guardian blog… Continue reading Dinosaurs Are Too Easy
Quantum Mechanics Is Square: “Ruling Out Multi-Order Interference in Quantum Mechanics”
This week’s big story in physics is this Science paper by a group out of Austria Canada (edited to fix my misreading of the author affiliations), on a triple-slit interference effect. This has drawn both the usual news stories and also some complaining about badly-worded news stories. So, what’s the deal? What did they do… Continue reading Quantum Mechanics Is Square: “Ruling Out Multi-Order Interference in Quantum Mechanics”
Real Math Doesn’t Use Calculators
The Dean Dad is worried about remedial math: In a discussion this week with someone who spends most of her time working with students who are struggling mightily in developmental math, I heard an argument I hadn’t given much thought previously: students who have passed algebra and even pre-calc in high school frequently crash and… Continue reading Real Math Doesn’t Use Calculators

slacktivist: Credit scoring and unemployment “Say you’re unemployed and you decide to work your tail off to land a new job, so you send out 40 résumés a week. Half of the companies might decide to do a credit-check before getting back to you. This sets off alarm-bells at the credit-rating agencies. Twenty credit-checks in… Continue reading Links for 2010-07-23
Thursday Toddler Blogging 072210
After a hard day of toddling, sometimes you just need to kick back on the couch with your sky-bison, and munch on a fruit strip: You know what I mean?
Sex, Intuition, and Evidence in Science
Over at A Most Curious Planet, Alexandra Jellicoe offers a story with the provocative headline Is Science Sexist?, which spins off an anecdote from astronomy: I was listening to Radio 4 a few months ago and the discussion about gender intelligence lodged in the deeper recesses of my brain unthought-of until recently when I went… Continue reading Sex, Intuition, and Evidence in Science
The E-Book Experience
A bit more than a month ago, I got a Sony Reader as a birthday present, upgrading my electronic book-reading platform from an old Palm Pilot. this is, obviously, not as sexy as a Kindle or a Nook, but then again, it doesn’t involve me paying fees to use wireless services and further stoke my… Continue reading The E-Book Experience
Teleconference Poll
Pretty much what the title implies: for a variety of reasons, I find myself in a position where people keep holding or suggesting conference calls as a way of getting the relevant players together on the phone if not in person. I’m not wild about this, but I’m curious what other people think: Conference calls… Continue reading Teleconference Poll
