I, for one, have always wanted to know…

Readers will know the Large Hadron Collider, the massive particle accelerator built to answer such questions as “Is there a ‘God Particle” (Higgs Boson)?”  The LHC accelerates two counter-rotating beams of protons to nearly the speed of light and then brings them into collision inside giant, cathedral-sized detectors that study the subatomic debris that comes flying outward.  The folks at CERN, who operate the LHC, hold the world’s record for the highest energies ever achieved: the collisions of more than 10 billion protons per bunch at a total energy of 2.36 trillion electron volts, or TeV, per collision.

But the LHC raises as many questions as it hopes to answer…

Who hasn’t wondered, for example, what happens if one puts one’s hand in front of the beam?  Happily (if not conclusively), the folks at Sixty Symbols have gathered some answers:

As we think hard about wearing gloves, we might recall that it was on this date in 1969 that a number of meteor fragments fell near Murchison, in Victoria, Australia.  Analysis of the fragments has identified over 14,000 compounds in the carbonaceous chondrite; almost 100 of them, different amino acids, only 19 of which are found on earth…  encouraging proponents of “panspermia”– the proposition that life on earth was “jump-started” when key ingredients in the primordial soup dropped in from the Heavens.

I was expecting… well, a deep, booming voice…

Readers will recall the effort at CERN’s Large Hadron Collider to discover the Higg’s Boson— “The God Particle.”  The Telegraph reports that while the search for the sub-atomic fugitive continues, scientists have determined that, when it is created at the Swiss supercollider– if it is created— ” it will sound like several coins clattering around the bowl of a wine glass.”

Scientists used information from computer models to calculate what the creation of the particle will sound like, a process called “sonification”.

LHC Sound, a group of scientists, musicians and artists in London, has used data on the particles and matched it to qualities such as pitch and volume to determine how the collision will sound.

Dr Lily Asquith, who models data for the LHC and has contributed to the sound project, wrote on her blog: “Sound seems the perfect tool with which to represent the complexity of the data.

“Our ears are superb at locating the source and location of sounds relative to one another … We also have an incredible ability to notice slight changes in pitch or tempo over time and to recognise patterns in sound after hearing them just once.”

Read the full report here.

As we reinterpret the soundtracks of our lives, we might recall that it was on this date in 1742, in a letter to Leonhard Euler, that Christian Goldbach outlined his famous proposition, now know as “Goldbach’s Conjecture”:

Every even natural number greater than 2 is equal to the sum of two prime numbers.

It has been checked by computer for vast numbers– up to at least 4 x 1014– but remains unproved.

God to “God Particle” hunters: “Forget it”…

The Baguette Incident (source: foxypar4/flickr, via PopSci)

Pity the poor Large Hadron Collider, the largest and most powerful particle accelerator in the world, built to find the Higgs Boson— the “God Particle.”  It just can’t seem to find its feet.

First, a coolant leak destroyed some of the magnets that guide the energy beam. Then LHC officials postponed the restart of the machine to add additional safety features. Now, a piece of bread droped by a bird on a section of the accelerator has, according to the Register, shut down the whole operation.

The bird dropped some bread on an outdoor section of the gigantic device, eventually leading to significant over heating in parts of the accelerator. The LHC was not operational at the time of the incident, but the spike produced so much heat that had the beam been on, automatic fail-safes would have shut it down.

Was the baguette an accident?  Two scientists have theorized that the LHC is sabotaging itself from the future, to prevent mankind discovering the elusive Higgs Boson particle (link to paper at arXiv.org here); others have sued to shut down the LHC “before it destroys the world.”

As we spin the arrow of time, we might recall that first Flying Trapeze act was performed in Paris on this date in 1859 by Jules Leotard (who also designed the garment that bears his name).

The link missing in yesterday’s post– to the physics paper suggesting that the Large Hadron Collider may be sabotaging itself from the future– is restored.  Apologies.
