Public day demonstration

2013/04/29 // 0 Comments

I think it is safe to say that “everyone” is familiar with electron microscopy for looking at small things, but the same cannot be said for small-angle scattering. Introducing more people to the wonderful world of small-angle scattering may be one of the ways of getting more support for and interest in the technique. With this in mind, and with some contacts in the PR department, we managed to get last-minute approval to do a demonstration at the public day at [...]

TEDxTsukuba

2012/04/23 // 0 Comments

(just a quick post about interesting things to keep the blog alive. More interesting developments are afoot, I hope to be able to post about them shortly) I suspect that all of the readers here are familiar with the wonderful resource of fascinating talks that is TED.  Yesterday, a group of people had their first meeting for setting up a TEDxTsukuba event. We are planning to hold the event early July in the center of the city we are in. It is going to be small, partly due to TEDx rules which allow only 100 people to attend. I will give another shout out about this as soon as there is a website for the event, and then I will talk about it no more (rest assured). If you are interested in helping out, please leave a comment or drop me a [...]

Live Fourier Transform for Windows

2011/08/16 // 6 Comments

[Ed: a new, completely rewritten version of this code can be found here, with a precompiled Windows version available at the bitbucket site courtesy of Joachim Kohlbrecher] Since entering paternity leave, I have had little time to come up with something new to post here. However, one colleague was so kind as to send me his Windows version of the live fourier transform program discussed before. His runs on his Lenovo laptop (but may be more widely applicable) and uses the Windows built-in Matlab webcam code. Framerates are markedly better than my OS X code, but memory requirements are significant and reinitialisation of the camera every few seconds generates a flash. The code is available here, with many thanks to Jakob R. Eltzholtz for making his code available. If you have suggested improvements or changes, please do not hesitate to contact Jakob and/or [...]

Book review: Ben Goldacre’s “Bad Science”

2011/03/07 // 1 Comment

Hi all. Last week-end, while visiting friends nearby, a copy of the book “bad science” by Ben Goldacre was dropped in my lap. Having read the occasional post on his weblog (http://www.badscience.net/), I had already planned to get it. So I started reading the book with rather high expectations. (This copy, if I did not misunderstand my friend, happens to be an unofficial “homeless” book. The idea is that they are passed along after you have read them. An idea I [...]

Gamma rays from synchrotrons, an interview with dr. Daté

2011/02/18 // 0 Comments

There is something quite “evil genius” about shooting an electron beam with a laser, especially for non-physicists like me. That this causes gamma rays to emerge (back towards the laser) is perhaps even more interesting. Allow me to elaborate in slightly more scientific [...]
