Eta Carinae

Preview of a Forthcoming Supernova

At the turn of the 19th century, the binary star system Eta Carinae was faint and undistinguished. In the first decades of the century, it became brighter and brighter, until, by April 1843, it was the second brightest star in the sky, outshone only by Sirius (which is almost a thousand times closer to Earth). In the years that followed, it gradually dimmed again and by the 20th century was totally invisible to the naked eye.

The star has continued to vary in brightness ever since, and while it is once again visible to the naked eye on a dark night, it has never again come close to its peak of 1843.


The larger of the two stars in the Eta Carinae system is a huge and unstable star that is nearing the end of its life, and the event that the 19th century astronomers observed was a stellar near-death experience. Scientists call these outbursts supernova impostor events, because they appear similar to supernovae but stop just short of destroying their star.


Although 19th century astronomers did not have telescopes powerful enough to see the 1843 outburst in detail, its effects can be studied today. The huge clouds of matter thrown out a century and a half ago, known as the Homunculus Nebula, have been a regular target for Hubble since its launch in 1990. This image, taken with the Advanced Camera for Surveys High Resolution Channel is the most detailed yet, and shows how the material from the star was not thrown out in a uniform manner, but forms a huge dumbbell shape.

Eta Carinae is not only interesting because of its past, but also because of its future. It is one of the closest stars to Earth that is likely to explode in a supernova in the relatively near future (though in astronomical timescales the “near future” could still be a million years away). When it does, expect an impressive view from Earth, far brighter still than its last outburst: SN 2006gy, the brightest supernova ever observed, came from a star of the same type.

This image consists of ultraviolet and visible light images from the High Resolution Channel of Hubble’s Advanced Camera for Surveys. The field of view is approximately 30 arcseconds across.

Relativism

The Nobel Prize in Physics 1914 Max von Laue

I am not sure what I can add other then what I have already been saying toward logical deduction....I still need to get a handle on the essence of what is being said here in opening thread.

So with what I looked at, can we say that the deductive recognition of lets say symmetry would be in contrast to how you might look at the world in a relativistic sense versus Platonism.










See: Against Symmetry

This setting was used more I think in terms of how a scientist is explaining himself and his relationship with the way in which he had approached science.....yet I could see there were scientist who had adopted the Platonic Tradition. Example of Penrose and Coxeter were demonstrative of this idea?


5.4.3 Platonism and Relativism

Platonism is a family of views that get their name because they involve entities--propositions, properties, sets--which, like Plato's Forms, are held to be abstract, immutable things that exist outside space and time. On many platonistic approaches, concepts express abstract properties and beliefs are relations between people and abstract propositions. This suggests a way around some types of relativism, since people in quite different cultures could have many of the same beliefs (because they could believe the same abstract propositions), and a belief would be true just in case the immutable proposition it expresses is true.
The relativist may reply that platonistic accounts lead to severe difficulties in epistemology and semantics. The problem is that we are physical organisms living in a spatio-temporal world, and we cannot interact causally (or in any other discernible way) with abstract, causally inert things. Moreover, few people are aware of having any special cognitive faculty that puts them in touch with a timeless realm of abstract objects, neuroscientists have never found any part of the brain that subserves such an ability, such a view is not suggested by what is known about the ways children acquire concepts and beliefs, and nothing in physics suggests any way in which a physical system (the brain) can make any sort of contact with causally inert, non-physical objects. Moreover, if our minds cannot make epistemic contact with such things, it is difficult to see how our words and linguistic practices can make semantic contact with them.
None of this proves that abstract propositions don't exist, but it shows it isn't obvious that they do. There have been few debates between relativists and platonists over such matters, however, perhaps because the two views lie so far apart that their proponents cannot easily engage one another.

So these were two positions that were adopted within the push toward understanding the basis of science and it's mathematics.

In theory model development was pushed forward on the basis of such adoptions. Loop Quantum Gravity?

Quasicrystal: Prof. Dan Shechtman

Just throwing some stuff together in order to understand the extent of relativism as a universal truth, while seeking to understand the subjective realism that make up our individuality. As a layman I do not know if it will be useful under that admittance. You can judge for yourself of course.

Most people think of "seeing" and "observing" directly with their senses. But for physicists, these words refer to much more indirect measurements involving a train of theoretical logic by which we can interpret what is "seen."- Lisa Randall

If one was to solidify some basis to truth how would this be done? The question of a logic oriented view for me saw a basis in what Penrose was explaining using his Twistors, as a foundation in incorporating Fuzzy logic?

While examining the psychological model of Venn logic and TA combined, it was important that there be some relative framework for such a subjective interpretation of a logic orientated world. How subjectively could this have been managed?


Perspective of the Theoretical Scientist


So you have this history and theoretical perspective that sees the world in one way or another? How do you reduce it to a process through Computing that establishes a basis in machining the effects of [and\or-so that we say a statement is .7 true and .3 false.]? We've created a space in between a true and false statement?

DNA computing is a form of computing which uses DNA, biochemistry and molecular biology, instead of the traditional silicon-based computer technologies. DNA computing, or, more generally, molecular computing, is a fast developing interdisciplinary area. Research and development in this area concerns theory, experiments and applications of DNA computing See:DNA computing

Entanglement then provides for other understanding then of a framework that sees the interrogation of a subjective world?


Do we selectively ignore other models from artificial intelligence such as Zadeh's Fuzzy Logic? This is a logic used to model perception and used in newly designed "smart" cameras. Where standard logic must give a true or false value to every proposition, fuzzy logic assigns a certainty value between zero and one to each of the propositions, so that we say a statement is .7 true and .3 false. Is this theory selectively ignored to support our theories? Ideas on Quantum Interrogation

Geometry Leads us to the Truth?

Part of the realism here for me is the idea that such patterns established deep within our psyche are inherent in each of us as an image first to our awareness, but encompasses a geometric patten of sorts. This was part of the work I did on myself as I explored the realm of dreams. The idea then manifested in what was the basis of this thought process as mandala in origins. A historical vision of an ancient idea of model building. In today's world I thought this as appropriate toward how theoretical ideas are built around a whole history of science and information.

On the Question of a Daemon

( Arthur Koestler on Creativity )


 You’ve seen it before? Perhaps you found it scrawled in goat’s blood on the walls of an abysmal abbey, written in the crabbed hand of one who purported to teach the whole of the law...Ain Soph

Just so you understand that what happens in the past may have set the course for humanity in thinking such and such so  is with some concern that anyone would think that what I had to say resounds with such historical distaste of what the future might bring?

Historical Figures Lead Us to the Topic of Entanglement

 
We do no want to be ever so arrogant that we cannot see the seeds of the past had paved the way for our understanding of that future and spread the progression of the subject so as to be well founded in experimental processes necessary.



But, said Timarchus, I see nothing but stars leaping about the hollow, some carried into it, and some darting out of it again. These, said the voice, are Daemons; for thus it is. Every soul hath some portion of reason; a man cannot be a man without it; but as much of each soul as is mixed with flesh and appetite is changed, and through pain or pleasure becomes irrational. Every soul doth not mix herself after one sort; for some plunge themselves into the body, and so in this life their whole frame is corrupted by appetite and passion; others are mixed as to some part, but the purer part still remains without the body, — it is not drawn down into it, but it swims above, and touches the extremest part of the man’s head; it is like a cord to hold up and direct the subsiding part of the soul, as long as it proves obedient and is not overcome by the appetites of the flesh. That part that is plunged into the body is called the soul, but the uncorrupted part is called the mind, and the vulgar think it is within them, as likewise they imagine the image reflected from a glass to be in that. But the more intelligent, who know it to be without, call it a Daemon. Therefore those stars which you see extinguished imagine to be souls whose whole substances are plunged into bodies; and those that recover their light and rise from below, that shake off the ambient mist and darkness, as if it were clay and dirt, to be such as retire from their bodies after death; and those that are carried up on high are the Daemons of wise men and philosophers. See:A DISCOURSE CONCERNING SOCRATES’S DAEMON. - Plutarch, The Morals,

The question raises the idea that with "matter trained" we had lost our way in terms of what matters. What we work has somehow become the the part of the belief that we no longer hold to what spiritually might be capable of, but steadfastly have chosen matter as the principle of some higher intelligence?

Journal Club

A journal club is a group of individuals who meet regularly to critically evaluate recent articles in scientific literature. Journal clubs are usually organized around a defined subject in basic or applied research. For example, the application of evidence-based medicine to some area of medical practice can be facilitated by a journal club. Typically, each participant can voice their view relating to several questions such as the appropriateness of the research design, the statistics employed, the appropriateness of the controls that were used, etc. There might be an attempt to synthesize together the results of several papers, even if some of these results might first appear to contradict each other. Even if the results of the study are seen as valid, there might be a discussion of how useful the results are and if these results might lead to new research or to new applications.

Journal clubs are sometimes used in the education of graduate or professional students. These help make the student become more familiar with the advanced literature in their new field of study. In addition, these journal clubs help improve the students' skills of understanding and debating current topics of active interest in their field. This type of journal club may sometimes be taken for credit. Research laboratories may also organize journal clubs for all researchers in the lab to help them keep up with the literature produced by others who work in their field.

 History

The earliest references to a journal club is found in a book of memoirs and letters by the late Sir James Paget, a British surgeon, who describes a group at St. Bartholomew's Hospital in London in the mid-19th century as "a kind of club ... a small room over a baker's shop near the Hospital-gate where we could sit and read the journals."[1]
Sir William Osler established the first formalized journal club at McGill University in Montreal in 1875. The original purpose of Osler's journal club was "for the purchase and distribution of periodicals to which he could ill afford to subscribe."[2]

Intuition

Like Truth.....how is it one could have found any use of such an subjective tool while recognizing something inherent in the process of discovery? Your thoughts?

Here's two quotes for consideration.

Intuition and Logic in Mathematics by Henri Poincaré

On the other hand, look at Professor Klein: he is studying one of the most abstract questions of the theory of functions to determine whether on a given Riemann surface there always exists a function admitting of given singularities. What does the celebrated German geometer do? He replaces his Riemann surface by a metallic surface whose electric conductivity varies according to certain laws. He connects two of its points with the two poles of a battery. The current, says he, must pass, and the distribution of this current on the surface will define a function whose singularities will be precisely those called for by the enunciation.

Felix Klein on intuition

It is my opinion that in teaching it is not only admissible, but absolutely necessary, to be less abstract at the start, to have constant regard to the applications, and to refer to the refinements only gradually as the student becomes able to understand them. This is, of course, nothing but a universal pedagogical principle to be observed in all mathematical instruction ....

I am led to these remarks by the consciousness of growing danger in Germany of a separation between abstract mathematical science and its scientific and technical applications. Such separation can only be deplored, for it would necessarily be followed by shallowness on the side of the applied sciences, and by isolation on the part of pure mathematics ....

In context of examination while not mathematically trained I was always curious about the process unfolding.... the foundations and their beginnings. The Sound Of Billiard Balls

Dirac became proof for me of the issue of being abstract while needing the image to go with it? Symbolically recognized while analytically described. So his axiomatic stance lead me to question why how and why Feynman designed his "word art(feynman diagrams)?"

When one is doing mathematical work, there are essentially two different ways of thinking about the subject: the algebraic way, and the geometric way. With the algebraic way, one is all the time writing down equations and following rules of deduction, and interpreting these equations to get more equations. With the geometric way, one is thinking in terms of pictures; pictures which one imagines in space in some way, and one just tries to get a feeling for the relationships between the quantities occurring in those pictures. Now, a good mathematician has to be a master of both ways of those ways of thinking, but even so, he will have a preference for one or the other; I don't think he can avoid it. In my own case, my own preference is especially for the geometrical way.Paul Dirac
Part of finding this truth is a deep examination(deep play) of what has been perpetuated so far and a meta look synopsis at how to gather and explain it so as to move on.

The deeper truth is an image that has to be explained? Part of our innateness has left an impression on the soul and recognizing the "time capsule" that is mandala in origins, is the method by which the soul engages what explodes back into their consciousness? This arises from a subconscious level and so too having traveled there you recognize what happens when you touch the very core of your being?

While I may refer to the geometric as inherent in such a truth in expression as some light behind us shining our shadow on the cave walls, these geometries can be covered by ancient designs and can lead the soul back to this beginning?

While you were looking out there, you were looking inside.

***
On developing the intuition I had a comment that I wanted to bring together here so it is understood that while we may hold science as a standard within our question for knowledge it is also required that we learn to understand somethings about ourselves in that process.

The Truth

The value of non-Euclidean geometry lies in its ability to liberate us from preconceived ideas in preparation for the time when exploration of physical laws might demand some geometry other than the Euclidean. Bernhard Riemann

Yes, this is what I had in mind too, as too identify the last place with which the historical paved the way to meeting Non Euclidean.





The amount of dark matter and energy in the universe plays a crucial role in determining the geometry of space. If the density of matter and energy in the universe is less than the critical density, then space is open and negatively curved like the surface of a saddle Geometry of the Universe

With it's application understood in terms of how one might see the shape of the universe, the truth in understanding is the search for how our universe does have a basis in a geometrical truth? What shape then?

Riemannian Geometry, also known as elliptical geometry, is the geometry of the surface of a sphere. It replaces Euclid's Parallel Postulate with, "Through any point in the plane, there exists no line parallel to a given line." A line in this geometry is a great circle. The sum of the angles of a triangle in Riemannian Geometry is > 180°.


If one understands the purpose of the truth with which is presented "on the scales" what relationship is subjectively compared to how gravity may affect the idea of an emotive world that is circumspect by our views being contained/weight. It could be as much "as a fog that exists" until some idea of a "clear light like perspective" is understood? How our perception of earth has now been transformed from the pearl in space to some strange looking rock in space

***
Galileo Galilei

In 1586 at the age of 22, Galileo (1564-1642) wrote a short treatise entitled La Bilancetta (“The Little Balance”). He was skeptical of Vitruvius’s account of how Archimedes determined the fraud in Hiero's crown and in this treatise presented his own theory based on Archimedes’ Law of the Lever and Law of Buoyancy. He also included a description of a hydrostatic balance that determined the precise composition of an alloy of two metals.

So on a subjective level we want to put forward the best constitution that we can so we try and find the basis of this truth as it would apply to all people. I think this is what came out of Benjamin Franklin when he was involved in the writing of the US Constitution. perusing Jefferson words as to better clarify the meaning of.

We hold (they say) these truths to be self-evident: That all men are created equal. In what are they created equal? Is it in size, understanding, figure, moral or civil accomplishments, or situation of life? Benjamin Franklin-The Gentleman's Magazine, vol. 46, pp. 403–404)

When I spoke of Benjamin Franklin I was referring to a philosophical truth that is inductive\deductive.




Our attempt to justify our beliefs logically by giving reasons results in the "regress of reasons." Since any reason can be further challenged, the regress of reasons threatens to be an infinite regress. However, since this is impossible, there must be reasons for which there do not need to be further reasons: reasons which do not need to be proven. By definition, these are "first principles." The "Problem of First Principles" arises when we ask Why such reasons would not need to be proven. Aristotle's answer was that first principles do not need to be proven because they are self-evident, i.e. they are known to be true simply by understanding them.

Even with all the scientific truth that is as tested, as an individual finding that place within with which such a conclusion is arrived at.....is much like "setting the tone" that will reverberate though your whole life?

The truth is not just mathematical although such reductionism can be sought to have been derived from First Principles? Where is this place? Where inside is this place?

Beacons of Discovery

To discover what our world is made of and how it works at the most fundamental level is the challenge of particle physics. The tools of particle physics—experiments at particle accelerators and underground laboratories, together with observations of space—bring opportunities for discovery never before within reach. Thousands of scientists from universities and laboratories around the world collaborate to design, build and use unique detectors and accelerators to explore the fundamental physics of matter, energy, space and time. Together, in a common world-wide program of discovery, they provide a deep understanding of the world around us and countless benefits to society. Beacons of Discovery presents a vision of the global science of particle physics at the dawn of a new light on the mystery and beauty of the universe. See: Beacons of Discovery

Message Sent Through Rock Via Neutrino Beam

See:Cern Courier:The right spin for a neutrino superfluid

If like myself you are watching the history of communication,  it becomes important to understand the advances we have on the horizon for when we are looking across the expanse of space for consideration of that information transference.


MINERvA: Bringing Neutrinos into Sharp Focus

 
Like radio waves, neutrino beams spread out. Moving farther away from the neutrino source is somewhat like driving away from a radio tower: Eventually you lose the signal. Until physicists create more intense beams of neutrinos or build more powerful detectors, the goal of using neutrinos to communicate with people under the sea or outside Earth’s orbit will remain out of reach.See:Scientists send encoded message through rock via neutrino beam
  While relativistic interpretations are understood with Muon detection scenarios we are able to understand some things about the earth that we had not known before. So in this case we see where such communications are already defining for us some information about the world we live in.


 ***

 Update:

DEMONSTRATION OF COMMUNICATION USING NEUTRINOS
 Beams of neutrinos have been proposed as a vehicle for communications under unusual circumstances, such as direct point-to-point global communication, communication with submarines, secure communications and interstellar communication. We report on the performance of a low-rate communications link established using the NuMI beam line and the MINERvA detector at Fermilab. The link achieved a decoded data rate of 0.1 bits/sec with a bit error rate of 1% over a distance of 1.035 km, including 240 m of earth.


ICARUS: the neutrino speed discrepancy is 0, not 60 ns

 ***
 We examine the possibility to employ neutrinos to communicate within the galaxy. We discuss various issues associated with transmission and reception, and suggest that the resonant neutrino energy near 6.3 PeV may be most appropriate. In one scheme we propose to make Z^o particles in an overtaking e^+ - e^- collider such that the resulting decay neutrinos are near the W^- resonance on electrons in the laboratory. Information is encoded via time structure of the beam. In another scheme we propose to use a 30 PeV pion accelerator to create neutrino or anti-neutrino beams. The latter encodes information via the particle/anti-particle content of the beam, as well as timing. Moreover, the latter beam requires far less power, and can be accomplished with presently foreseeable technology. Such signals from an advanced civilization, should they exist, will be eminently detectable in neutrino detectors now under construction. See:Galactic Neutrino Communication by John G. Learned, Sandip Pakvasa, A. Zee

Rara Avis in Terris Nigroque Simillima Cygno

Statistical and applied probabilistic knowledge is the core of knowledge; statistics is what tells you if something is true, false, or merely anecdotal; it is the "logic of science"; it is the instrument of risk-taking; it is the applied tools of epistemology; you can't be a modern intellectual and not think probabilistically—but... let's not be suckers. The problem is much more complicated than it seems to the casual, mechanistic user who picked it up in graduate school. Statistics can fool you. In fact it is fooling your government right now. It can even bankrupt the system (let's face it: use of probabilistic methods for the estimation of risks did just blow up the banking system).THE FOURTH QUADRANT: A MAP OF THE LIMITS OF STATISTICS [9.15.08]  By Nassim Nicholas Taleb
