The Great Galilean Race

The competitors in this racing are introduced in the previous entry about Galileos inclined plane experiments  Galileo And Relativity- But More About Inclined Planes And Fun Simulations, which perhaps have not been really performed, but which we can find ...

Who Is Today's Einstein? An Exercise In Ranking Scientists

Who cites who? Science funding, tenure track appointments, all that is important to young scientists gets more and more dominated by citation analysis. This is certainly true in physics. Physics is very much a cumulative endeavor. Each physicist builds on ...

All these sciences xx.xx

Well, I thought that Science 2.0 would be enough for my needs, whatever that means. But then I found Science 3.0, made probably because 2.0 was already taken. Science 3.0 has different aims, it is not about outreach, but about collaboration between scienti ...

Two Feature Articles In Print Next Month

Now that the two articles I have worked on in the past two months are finalized, I think I can disclose where and when they will be published. In the March 2011 issue of Physics World you will find two back-to-back feature articles on the LHC in 2011. Auth ...

Quantum Perspective On The Non-Existence Of Light

Einstein’s relativity theory and quantum physics, in theory as well as experiment, are extremely concerned with light. This comes directly from the fact that light does not exist as an independent entity – it is plain interaction. I explained already how ...

B Cross Sections From CMS

Embarassingly overdue, the slides of my talk on "Heavy Flavour and Quarkonia Production in 7 TeV pp Collisions", meant for the 2011 Les Houches meeting on "Recent Advances in QCD" to be held next week near Chamonix, France, are slowly c ...

What's Going On Around

The physics with LHC is becoming rapidly awesome, and being part of the CMS experiment and deeply involved in some technical aspects of the analyses (the statistical treatment of the data, and the control of the statistical claims of the scientific papers ...

Simulation Hypothesis And Other Silly Religious Stuff

After arguing against ‘higher consciousness’ or freedom evolving, let us go on to discuss consciousness inside computers. This is, maybe surprisingly so for some readers, closely connected with the non-existence of gods and in fact quantum theory. Ironica ...

Time flows

Time flows. Newton seemed to think so. So did Aristotle and countless others before. Even the Buddhists, with their cyclic time, kept believing that time was something which went from one instant to the other, moving forward though in circles. That, of co ...
