Lessons in outreach to be learned from Japan’s disasters
(warning: this rather lengthy piece may contain personal opinions and has little to do with small-angle scattering. There is a nice bit about graphics, though.) In the wake of the global public panic following the reporting around the nuclear reactor struggles (as opposed to the expected >15 kilopeople deaths in Myagi prefecture due to [...]
Live FT video
A demonstration of the live Fourier Transform showing scattering patterns can be seen here:
Live Fourier transform
During some recent presentations, I have used a small matlab program giving me a live Fourier transform of the laptop camera input. It can be used in combination with some printed “structures” to show what we would see on a SAXS or WAXS detector. The idea is not mine, I heard that it was used [...]
Notes on Guinier
…well, his famous SAXS analysis method. This documentGuinier_short, copyright Brian Pauw gives a short description and review of the applicability of the Guinier method to polydisperse systems. It also shows, through analysis of simulated data, what q-range should be measured for the Guinier method to be valid. In short, the rule of qmax=1.3/Rg still holds, [...]
More Youtube videos
So, I could not do what I promised last time, the Monte-Carlo fitting works on perfect simulated scattering patterns but is as of yet unable to deal with the addition of a flat background. So I will have to take a raincheck. In the mean time, I have made two videos (part 1 and part [...]
Teaching and how it applies to us.
We teach. Every one of us. If we have a classroom of students, it is obvious, but also when we talk to colleagues, we sometimes try to teach them something (even if it is only our point of view). I spoke last time about the teaching horrors that modern textbooks have. Well, this video by [...]
Dresden codak – detailed visual narration lessons from comics
There is a scathing review coming out on the topic of academia (particularly the US one). While the general tone of the dissertation is negative, they do indicate a strong need, or rather duty, of scientists to communicate our findings as clear and understandibly as possible. Personally, I completely agree with this. Clear communication sometimes hinges [...]
Holiday reading, watching and writing.
Hi all, I found some interesting papers for you, and a talk. Let me start with the talk. It is a TED talk (naturally) concerning TED talks. This nice introspective talk is actually of interest for all of us as it gives a few pointers to the set-up of excellent (and terrible) talks, with a [...]
New 2D SAXS movie
I have a new movie made, which may be a bit more suited for those of you working with isotropic samples. Instead of a bundle of filaments it now displays a box of isotropic scatterers at the sample position. Please feel free to download and use this one in your presentations. You can also contact [...]
TED is coming to Europe this summer!
Good news for all of you keeping up with current affairs in the worlds of Technology, Entertainment and Design: There is a TED conference coming to Europe this summer! So if you are unwilling to travel to the US, you can now travel to the UK instead, and join the conference from 12-16th of July [...]
