If you want clicks, then now is the time to write about earthquakes and nuclear disasters. That is why Science 2.0 has now an article telling us how great it is that the quake hit Japan, because Japan is so well prepared, and this is mostly thanks to the good folks from science and technology, so no wonder there are only a mere 1000 dead to count. Another article presents us with press releases of Japanese nuclear reactor officials trying to calm the panic.

This from the BBC:

“Germany has been named as the most supportive country for overseas students, in an international league table.”

If you are a student looking for international experience, you should go to Germany. Why the hell go to the US and pay huge fees for worse education, mostly confined in the culturally impoverished, numbing atmosphere of US cities with one of the few exciting aspects being the fear of getting shot at? (I was shot at in LA!)

Well, the language of course! Guess what – the new reason for studying in Germany instead of the US or UK is: German lecturers speak better English!  ROFL

Superfluid liquid Helium is shot under very high pressure out of a tiny nozzle and into vacuum. Outside in front of the nozzle, the excess pressure bursts the liquid apart violently into a myriad of fragments. A cloud of ultra small droplets comes into existence. The liquid beam is almost completely atomized.

If you take a randomly drawn droplet from the explosion, the number of atoms inside of it is mostly just one, a single atom. Finding two atoms is less likely, three atoms even less, and so on.

Every once in a while we are told that Schrödinger’s cat is now proven. One incarnation of the ‘Finally Proven!!!’ of macroscopic quantum superposition was hailed as one of the 10 breakthroughs, the breakthrough of the year 2010. By Science about an article in Nature [1], no less!

Quantum physics and Einstein’s relativity theory, in theory as well as experiment, are extremely concerned with light and its photons. Why should fundamental science be obsessed with something so feeble? Well, it could not be any other way! Science is about what we can (experimentally) observe. As physics advances, it must be expected to be more and more concerned about the most reliable way to measure. It must investigate observation as such.

“Yesterday night I was in my office in the Department of Chemistry at the University of Cambridge packing my stuff, resolved to not go back to research again …”

This sad story is another warning to all those enthusiastic about getting into science. One more outtake:
