European collider begins its subatomic exploration
European collider begins its subatomic exploration
By Dennis Overbye New York Times Posted: 03/30/2010 07:10:23 AM PDT Updated: 03/30/2010 08:58:51 PM PDT After 16 years and $10 billion, there was joy in the meadows and tunnels of the Swiss-French countryside Tuesday: The world's biggest physics machine, the Large Hadron Collider, finally began to smash subatomic particles together. After two false starts due to electrical failures, protons whipped to more than 99 percent of the speed of light and to record-high energy levels of 3.5 trillion electron volts apiece raced around a 17-mile underground magnetic track outside Geneva. They crashed together inside apartment-building-sized detectors designed to capture every evanescent flash and fragment from microscopic fireballs thought to hold insights into the beginning of the universe. The soundless blooming of proton explosions was accompanied by the hoots and applause of scientists at CERN, the European Organization for Nuclear Research, which built the collider. Among their top goals are finding the identity of the dark matter that shapes the visible cosmos and the strange particle known as the Higgs boson, which is thought to imbue other particles with mass. Rolf-Dieter Heuer, director general of CERN, said Tuesday from Japan that the new collider "opens a new window of discovery and it brings, with patience, new knowledge of the universe and the microcosm."

Here is a nice presentation of the CERN's supercollider by Physicist Brian Cox (a very nice person) :

Ha! Ha! Sarah, you are an Attractive Female on a mostly male oriented forum. I think you can say and post just about anything you desire and no one will complain.

If Sarah gave a reason to complain, we would say something. (Preferably as PM.) So far, everything is good.  (We try to do our job free of preferential treatment.)

Don't get me wrong. There are days where I lose a lot of money, and want to jump off of a building. In the long run, I play better than my opponents, and that is how the money is made. I love being my own boss. The money is better than my last job at Starbucks. |

Kiddie particle physics
Quote:
I NEVER expected to happen upon someone like you on this site... or anywhere else for the rest of my life, given how exotic your work is! Encountering you exhumes ancient childhood memories and dreams. A half-century ago, I was a small boy attending the New York World's Fair with my parents. In the fair's Hall of Science pavilion, I picked up three booklets in the Understanding The Atom series, intended for the education of the general public, and published by a US federal agency then called the Atomic Energy Commission (AEC). I found them fascinating and would write away for many more of these wonderful free booklets in the next few years to come! I would even dream about becoming an elementary particle physicist when I grew up - until the huge cutbacks in US federal R&D that came at the end of the 1960's persuaded me that I would never be smart enough to make such an outlandish dream come true. I last thought about these booklets DECADES ago - even if it's not impossible they are packed away in an old box still in my possession. Today I looked for them online - and guess what? The US Department of Energy has just this year published copies of them online here! My favorite booklet, whose nearly-torn-away cover testified to my repeated handling of it, was Microstructure of Matter, which described the elementary particles which your guys study at CERN, although it reflected our more limited understanding of those times - before the Standard Model reached maturity. Later, as a university undergraduate, I would never study particle physics, and as simple as this booklet was, it nonetheless provided me with the knowledge I needed to correctly answer two questions regarding this discipline which appeared in the Physics Graduate Record Exam (GRE) I took circa 1975! But back in my childhood days, I would dream about actually doing experimental particle physics and so became interested in the construction of particle accelerators. For this, the aforementioned series provided the volume titled Accelerators. My parents were struggling immigrants with primary school educations, and there was nothing like the World Wide Web to which to turn, so the exotic specialty information provided by such a booklet in those days was a miraculous treasure to a boy like me! Because I had the good fortune to live in a major US city, I eventually could borrow Livingston and Blewett's Particle Accelerators (McGraw-Hill, 1962), too. But as I didn't even study single-variable calculus until my last year of secondary school, the book's routine use of Maxwell's equations made it rather inaccessible to me. Yet I dreamt about building first, a Van de Graaf machine, and later, a cyclotron. Alas, my family was far too poor (and troubled!) for me to make brave ambitions like that really come true before I left home for university and went on to study other areas of science and technology. (Yet, oddly enough, as a condensed matter physicist, I would land up effectively leveraging cyclotron resonance via inelastic light scattering!) However, since one needs all sorts of power supplies to build such machines, and an oscillator to excite the dees of the cyclotron, I was drawn into electronics, in which I actually made substantial progress. In those days, television sets not only used a vacuum tube for a display, but also exploited vacuum tubes as active circuit elements. I would salvage discarded TV sets from the trash, and desolder and test the components therein, to stock my supply larder! My father had given me a soldering iron when I turned eight, and I am proud to say I only injured myself with molten solder on my hand once - such a lesson is always memorable! Curiously, the AEC series also included a volume titled Computers, which introduced me to machine computation, then an exotic branch of electronics. That field proved of more practical value to me, and I landed up creating a paper design which functionally cloned a small contemporary computer, which I would enter into a national "science" contest to during my last year of secondary school. In closing, for the benefit of others reading here, I'd like to mention that old-fashioned particle track imaging devices, which produced images such as the one you posted above, are described in the Microstructure of Matter booklet, and the storage ring device which today keeps you so busy was already an active area of work a half-century ago, and is described on pages 47 and 48 of the Accelerators booklet!
