Anybody seen Ai Weiwei recently?

In our small universe the thought of supressing an idea, an ideal by simply locking up one person representing it, seems so very archaic. Nevertheless, this still is the approach of chinese authorities, who detained the internationally renowned and sometimes mercilessly critical artist Ai Weiwei on sunday. The voices for free speach became louder ever since.
Cultural Development folks at Platoon (www.platoon.org) suggest to print out this image of Ai Weiwei and display it everywhere in public. Read this: http://blog.platoon.org/home/3/viewentry/1233

Academics should be blogging? No.

"blogging is quite simply, one of the most important things that an academic should be doing right now" The London School of Economics and Political Science states in one of their, yes, Blogs . It is wrong. The arguments just seem so right: "faster communication of scientific results", "rapid interaction with colleagues" "responsibility to give back results to the public". All nice, all cuddly and warm, all good. But wrong. It might be true for scientoid babble. But this is not how science works. Scientists usually follow scientific methods to obtain results. They devise, for example, experiments to measure a quantity while keeping the boundary-conditions in a defined range. They do discuss their aims, problems, techniques, preliminary results with colleagues - they talk about deviations and errors, successes and failures. But they don't do that wikipedia-style by asking anybody for an opinion . Scientific discussion needs a set...

Left Brain, Right Brain

At a wonderful summer night I was lying in the grass, my little son beside me. We were staring into the dark sky, debating infinity, other planets, the origin of everything, observing falling stars that were whizzing through the atmosphere at a delightfully high rate. Why did we see so many of them that night? What are falling stars? What are comets. Why do comets return and when? The air was clear and warm. No artificial lights anywhere. The moon was lingering lazy in the trees across the river. Some fireflies were having a good time, switching their glow on and off rather randomly - in one group they seemed to synchronize but then it was random again. It reappeared: a few bugs were flashing simultaneously at first ... it started to expand, it was getting more. A whole cloud of insects was flashing in tune. Are they doing this on purpose? Do they have a will to turn the light on and off? How do those fireflies communicate? And why? Do they communicate at all? My son pointed at a fie...

My guinea pig wants beer!

Rather involuntary train rides (especially long ones, going to boring places for a boring event) are good for updates on some thoughts lingering in the lower levels of the brain-at-ease. My latest trip (from Berlin to Bonn) unearthed the never-ending squabble about the elusive 'free will'. Neuroscientists make headlines proving with alacrity the absence of free will by experimenting with brain-signals that precede the apparent willful act - by as much as seven seconds! Measuring brain-activity way before the human guinea pig actually presses a button with whatever hand or finger he desires, they predict with breathtaking reproducibility the choice to be made. So what? Is that the end of free will? I am afraid that those neuroscientists would accept only non-predictability as a definite sign of free will. But non-predictability results from two possible scenarios: a) a random event (without a cause) b) an event triggered by something outside of the system (but caused). ...
