Let’s say you have a mirror– not some cheesey $2 makeup mirror, but a research-grade aluminum mirror– and it has some crud on it, say a film of junk deposited during your Summer Institute for Hot MEtal Chemistry. Like, say, the mirror on the right in this picture: How do you get that mirror clean?

Watching Wavefunctions Collapse
In a comment to the book announcement, “HI” makes a request: Would you be able to summarize the recent paper “Progressive field-state collapse and quantum non-demolition photon counting” (Nature. 2007 Aug 23;448(7156):889-93) for non-specialists? How do you interpret it? This probably would’ve slipped by me if not for this comment, but it’s a really nice… Continue reading Watching Wavefunctions Collapse
Teh AMO hottness
I should probably sneak in a few posts before Chad gets back. It’s been a hectic week, as the time came for my current experiment (as it does for all experiments) where one stops futzing around trying to make things better, and takes the actual data, with an eye to moving on. This means that… Continue reading Teh AMO hottness
Flying Things
Steinn reports that the NRC has made its recommendations for NASA’s Beyond Einstein program. The winners appear to be LISA, a gravity wave observatory, and JDEM, a competition of dark energy focussed satellites. Steinn has lots of links to the various projects. The executive summary of the report is availabe here (pdf). I know next… Continue reading Flying Things
“It’s a monstrosity,” Brown said.
A little while ago, intrepid reporters from the Baltimore Sun dropped by my lab to investigate the newsworthiness of a paper (also on the ArXiv) that had just been published, about which I might talk a little bit before Chad gets back. Surprisingly, the article actually got published, complete with photo and great quotes. I’m… Continue reading “It’s a monstrosity,” Brown said.
Software for experimentalists
A long time ago, all you needed to think about and record the data you were interested in was a pen and some vellum, and maybe a few candles and a trusty manservant. Somewhere along the line, the chart recorder got invented, and when combined with the oscilloscope and those awful scope cameras, a whole… Continue reading Software for experimentalists
Crystal healing
Lest this blog turn into a one-trick pony, let me tell you what I did today that’s of a little different flavor. I epoxied some stuff onto some other stuff. More importantly, I calculated a band structure. This amazes me. Sure, all you squa^Wsolid-state types out there do this every day, over your cereal even,… Continue reading Crystal healing
Consider the vacuum (I)
While I’m sure there will be a lot of chatter around here in the next few weeks about the vacuum (or, God help me, vacua), I feel like I should lay the groundwork by talking about laboratory vacuum. I know I’m here to talk about cold atoms and the hot stuff going in in experimental… Continue reading Consider the vacuum (I)
Fundamental Research Funding
Michael Nielsen, who’s so smart it’s like he’s posting from tomorrow, offers a couple of provocative questions about the perception of a crisis in funding for basic science: First, how much funding is enough for fundamental research? What criterion should be used to decide how much money is the right amount to spend on fundamental… Continue reading Fundamental Research Funding
No Love for Germer?
I’m working on something at the moment that involves talking a bit about the historical development of quantum theory, and specifically the demonstration of the wave nature of electrons. One of the famous proofs of this is the Davisson-Germer experiment, showing that electrons bouncing off a nickel target produce a diffraction pattern. (As an aside,… Continue reading No Love for Germer?
