Mathematical functions are all around us. We may not realize it but they are there! Check it out on the pictures below.

A blade of light, selected by the venetian blinds of my living room window, draws a curved, complicated, multiple-valued function on the semi-transparent orange curtains. Maybe the curve below is even more fascinating:

In Control

Sep 22 2009 | 14 comment(s)

Most of us like to be in control: of what happens around us, of our own feelings, of our actions, of the actions and well-being of our beloved ones. Being in control means feeling secure, unthreatened. It is the prevalence of order on chaos. And chaos, I have grown to realize, is one of the things that scares me most. Yes, I am a true control freak.

(From Fermilab's Main Control Room logbook today)
The question of what will the next discovery at Fermilab be was asked in the thread of a recent article, and I initially answered it there, but then thought that expanding my answer makes excellent material for an independent article. Therefore, below I have tried to put together my own personal list of the places from where a unexpected new Tevatron discovery may come and hit us, in the near future.
I am spending my time in the CDF Control Room this week (seven days, from 4PM to midnight), as a Scientific Coordinator. My job is to work with my crew to ensure that the experiment collects good data as efficiently as possible. The data I am talking about is, of course, provided by our glorious accelerator, the Tevatron collider. Today I will tell you how the Tevatron is doing these days, and doing that will prepare the ground to my suggestion that you should become a fan of this wonderful machine.

A short introduction
I was notified today that within three weeks I am due to write a proceedings article for the "Physics in Collision" conference I attended in Kobe two weeks ago. The task is not too stimulating for me, given that the material it has to cover just consists in projections of the discovery reach of the Higgs boson, based on simulated data; but to add unexcitement to the whole thing, I found out that I am bound to stay within the limit of two pages of text.
In order to be able to perform unescorted access to areas where ionizing radiations are present, and to work with and use radioactive materials, workers at Fermilab have to pass a specific training which enables them to recognize the dangers and work safely, minimizing the radiation dose they get by performing their activities, and reducing the spread of contamination to the environment.
"There is, in my opinion, no doubt that by the time we are ready to announce the discovery of the Higgs boson, the whole world will know it".

Fermilab is a wonderful place to travel to in the late summer or fall. The site of the laboratory is a wide chunk of land just east of the Fox river, 30 miles west of Chicago. It is home to not just physicists and engineers, but to a wide variety of animals. Geese on their way South stop yearly in the lake in front of Fermilab's Wilson Hall, and many of them decide to spend the winter there, to benefit from the warm waters; deer are copious, but will not be easily seen around, save for the occasional one at times seen standing in the middle of the road at night; buffalos roam within large lots of land outside and inside the ring. Woods, trees with widely varied colours, and prairie make one feel it is a privilege to do Science there.
What happened to all the enthusiasm?  Perhaps new astronomy will shed light on the matter.
In 2005 the anniversary of Einstein's miracle year there was much talk of "new Einstien"s and why there have been no new ones.   Carlo Rovelli published a very good book on the subject.  String theory and M theory were as hot as the surface of the sun.  In a heated exchange on Wikipedia I made the acquaintance of Lubos Motl.   There was much excitement 4 years ago.  So what happened?  Why no accepted theory of quantum gravity?
