What is Cerenkov Radiation?

…the creative principle resides in mathematics. In a certain sense therefore, I hold it true that pure thought can grasp reality, as the ancients dreamed.Albert Einstein

Many do not recognize the process that unfolds in the developing perspectives about theoretics? Does one think it is divorced from reality that you could say, “hey this idea of course has no attachment to what exists and what we know exists and asks that you move forward with it.”

Often you hear the “dreaded reference” to the AEther, and who can help but see where such revisions in thinking changed the society of scientists to put them on a new course?

Do you think the title was changed from the aether to the valuation of strings and the boson production evident in the bulk just to replay itself in the developing scenarios of our historical past? The past included a revision to the way we view that concept? That is it’s effect in today’s world. “The correction?”

As we know from Einstein’s theory of special relativity, nothing can travel faster than c, the velocity of light in a vacuum. The speed of the light that we see generally travels with a slower velocity c/n where n is the refractive index of the medium through which we view the light (in air at sea level, n is approximately 1.00029 whereas in water n is 1.33). Highly energetic, charged particles (which are only constrained to travel slower than c) tend to radiate photons when they pass through a medium and, consequently, can suddenly find themselves in the embarrassing position of actually travelling faster than the light they produce!

The result of this can be illustrated by considering a moving particle which emits pulses of light that expand like ripples on a pond, as shown in the Figure (right). By the time the particle is at the position indicated by the purple spot, the spherical shell of light emitted when the particle was in the blue position will have expanded to the radius indicated by the open blue circle. Likewise, the light emitted when the particle was in the green position will have expanded to the radius indicated by the open green circle, and so on. Notice that these ripples overlap with each other to form an enhanced cone of light indicated by the dotted lines. This is analogous to the idea that leads to a sonic boom when planes such as Concorde travel faster than the speed of sound in air

But we have to go back in history here to see where such influences have taken hold of the mind, from what was instituted in the neutrino search, to have the ideas swirl around and form new prospect researches, based on the ideas of women/men?

The story will follow here shortly. I would like to thank Paul on his early recognition of the bubble chamber events as they encourage research in 1998 to ponder the experiments in Cern to say?

Add your story so that this can be completed. I will add mine for a wonderful view of what research and developement does in regards to the way of “modelling to experiment.”

Well since starting this blog entry there has only been two other examples that may be added to this entry as of today, yet, one by Commentor NC at Cosmic Variance while the other materialized over at Backreaction on the post done by Bee and Stefan.

A Look Back

Have a look at this image below first.

Variation of Cosmic ray flux and Global cloud coverage-a missing link in Solar-climate relationshipsby Henri Svensmark and Eigil Friis-Christensen, 26 NOvember 1996

So this is wonderful that in one way, where my mind rebukes the lashing out of Peter Woit by evidence of ICECUBe and my ir/relevant comments, could have found sustenance in how things are to be explained further? More physics …wonderful.

But I want to go back historically to view, so that one sees what was <a href="http://www.haloscan.com/comments/59de/116042814463429837/#209057&quot; target=_Blank title="I happen to be tranfixed by the Royal Chrismas Lecture given by Prof Frank Close, in the lecture it was showing Cosmic Ray detections, as then (1996)
“>a picture “written by Paul” and his trip to Canada, held an observation that sends us back in time experimentally to look at, to find out, what Cern was doing in 1998. Thanks Paul

You ready?

CERN plans global-warming experiment(1998)

A controversial theory proposing that cosmic rays are responsible for global warming is to be put to the test at CERN, the European laboratory for particle physics. Put forward two years ago by two Danish scientists, Henrik Svensmark and Eigil Friis-Christensen, the theory suggests that it is changes in the Sun’s magnetic field, and not the emission of greenhouse gases, that has led to recent rises in global temperatures.

Experimentalists at CERN will use a cloud chamber to mimic the Earth’s atmosphere in order to try and determine whether cloud formation is influenced by solar activity. According to the Danish theory, charged particles from the Sun deflect galactic cosmic rays (streams of high-energy particles from outer space) that would otherwise have ionized the Earth’s lower atmosphere and formed clouds.

So what is this science based on?

The production of a high-intensity neutrino beam at CERN requires a complex facility. A proton beam produced and accelerated by the CERN accelerators is directed onto a graphite target to give birth to other particles called pions and kaons. These particles are then fed into a system comprising two magnetic horns which focus them into a parallel beam that is directed towards Gran Sasso. Next, in a 1000 metre-long tunnel, the pions and kaons decay into muons and muon neutrinos. At the end of this decay tunnel, an 18 metre thick block of graphite and metal absorbs the protons, pions and kaons that did not decay. The muons are stopped by the rock. Impervious to all such obstacles, the muon neutrinos will leave the CERN tunnels and streak through the rock on their 732 kilometre journey to Italy.

Now what does this have to do with Cerenkov radiation? Okay. I’m scratching my head now.

“CERN has a tradition of neutrino physics stretching back to the early 1960s,” said Dr Aymar, “this new project builds on that tradition, and is set to open a new and exciting phase in our understanding of these elusive particles.”

From the 1960’s. Wow!

Imagine that someone might say to you that this is a “Rube Goldberg Machine” analogy as to what was the road leading to the understanding and the inclusiveness of microstate blackhole creation from particle collisions, as part of the continued story of the neutrino in action?
