After some remarks on my comment to Dr Kaku's (a popular figure from bigthink.com ) overpopularization of physics one more comment on the wave-properties of an electron seems appropriate: There is a famous experiment illustrating the consequences of the wave-description for the probability to find an electron at a given point in space. If an electron-source is placed in front of a metal-sheet with two narrow slits, a recording-device behind this screen would detect a distribution of incoming electrons that is identical to an interference-pattern of waves passing through the double slit (as would be seen when shining coherent, monochromatic light (a laser produces this kind of light) on the two slits). This interference-pattern shows up no matter how low the rate of electrons coming through. Even if only one single electron per hour would pass through the slits, there would, finally, be a distribution of detected electrons given by the well-known interference-pattern. This...

We got some angry reactions and shows of disgust and sadness to our report on carnivorous computers , which get their energy by digestion of small animals. While that brilliantly despicable idea was merely a design concept with no proof of real functionality, another designer popped up to save our soul: vegetarian lamps! Marieke Staps http://www.mariekestaps.nl/?/Design/Soil-Lamp-2/ from the netherlands developed soil-powered LED lighting that, according to her words only needs some watering every now and then, just like her chicque and totally pc eco-watch. (a little closer look reveals some copper and zink electrodes which, together with water of the right pH, are nothing but standard batteries. Nice idea though.)

Michio Kaku is featured on the website bigthink.com as a sympathetic elderly man able and willing to explain everything. On April 13 he tells us "why quantum physics ends the free will debate" . Well, sure. I am very supportive of the idea to popularize big scientific thoughts and achievements so that the broader public gets a glimpse of what is being mulled over in the head of those big shots. But I am totally allergic to oversimplification at the expense of the real message. Why does quantum physics supposedly end the free will debate? You guess it: because with Newtonian physics everything, every thought, every move you make every step you take was in principle predictable. The world was supposedly completely deterministic. You would just have to know all the parameters of the universe at the time of the big bang, then calculate and calculate until you arrive at your phase space of now and, voila, you could extrapolate into the future of your tremendously boring life. ...

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.
