Evidence for Extra Dimensions and IceCube

...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

Sometimes if we paid attention enough, the neurons seem to fire appropriately and the detachment of the ideas seemingly distant from one another, become illuminated and connected? Imagine it taking place in Clifford's other office.

Foundations Study Guide: Philosophy of Mathematics by David S. Ross, Ph.D.

The philosophy of mathematics is the philosophical study of the concepts and methods of mathematics. It is concerned with the nature of numbers, geometric objects, and other mathematical concepts; it is concerned with their cognitive origins and with their application to reality. It addresses the validation of methods of mathematical inference. In particular, it deals with the logical problems associated with mathematical infinitude.

Among the sciences, mathematics has a unique relation to philosophy. Since antiquity, philosophers have envied it as the model of logical perfection, because of the clarity of its concepts and the certainty of its conclusions, and have therefore devoted much effort to explaining the nature of mathematics.

Such a cognitive fucntion then would be important as these math symbols arose in our minds. Possible new mathematical models in which to describe the nature we see around us. So one makes sure they have a pad and pencil, while they ventured away from the regime, with which the mind has been so intensely engaged?

Now being so far from the understanding of these mathematics, I can only hope to understand the concepts as they unfold in a geometrical insight, while I try to make sure I understand them in relation to abstract thinking.

SNO on the go – at last!

Over the past 30 years, five different experiments have sought to measure the flux of these elusive particles from the Sun (produced by the same nuclear processes that make it shine) and have consistently come up short of theoretical predictions. One explanation is that the neutrinos emitted ‘oscillate’ into another variety of neutrino which past experiments could not detect.

Within the IceCube collaboration the Univ. of Uppsala and the Univ. of Berkeley have joined the DESY initiative. The DESY team is also in close contact to the groups in Europe, the USA and Asia which are working on acoustic detectors for Neutrino-Telescopes installed in water. Details on the different projects have been presented on the First Workshop on Acoustic Cosmic Ray and Neutrino Detection held at Stanford in September 2003.

The muon will travel faster than light in the ice (but of course still slower than the speed of light in vacuum), thereby producing a shock wave of light, called Cerenkov radiation. This light is detected by the photomultipliers, and the trace of the neutrinos can be reconstructed with an accuracy of a couple of degrees. Thus the direction of the incoming neutrino and hence the location of the neutrino source can be pinpointed. A simulation of a muon travelling through AMANDA is shown here (1.5 MB).

Some understanding of the dual nature of blackholes is needed here in order to understand what is "produced" and how this is "spread out."

"String theory and other possibilities can distort the relative numbers of 'down' and 'up' neutrinos," said Jonathan Feng, associate professor in the Department of Physics and Astronomy at UC Irvine. "For example, extra dimensions may cause neutrinos to create microscopic black holes, which instantly evaporate and create spectacular showers of particles in the Earth's atmosphere and in the Antarctic ice cap. This increases the number of 'down' neutrinos detected. At the same time, the creation of black holes causes 'up' neutrinos to be caught in the Earth's crust, reducing the number of 'up' neutrinos. The relative 'up' and 'down' rates provide evidence for distortions in neutrino properties that are predicted by new theories."

Before engaging article below it is important that the differences be noted between strangelets(strange quarks), and the distortions in neutrino properties. If it is understood the microstate blackholes are created, then the dispersion of other particle in the atmosphere give us indications and consequences gained from dual nature of the blackhole.

I am confused here, and this point of interactive consideration is holding my mind as to why both these situations together are important. The difficulty may come from from the immediate association, while reocgnition of these two have been raised from the event and collision.

Earth punctured by tiny cosmic missilesBy Robert Matthews, Science Correspondent

Strangelets - sometimes also called strange-quark nuggets - are predicted to have many unusual properties, including a density about ten million million times greater than lead. Just a single pollen-size fragment is believed to weigh several tons.

They are thought to be extremely stable, travelling through the galaxy at speeds of about a million miles per hour. Until now, all attempts to detect them have failed. A team of American scientists believes, however, that it may have found the first hard evidence for the existence of strangelets, after scouring earthquake records for signs of their impact with Earth.
