Full With Noise: Theory and Japanese Noise Music
by Paul Hegarty.......... "Full with Noise,..." is about noise music, specifically the version that has come to be called Japanese Noise -- itself composed of many different strands. The first half deals with the question of noise. What is it, whose is it, and how can we think about it. Also, how does noise inflect our thinking, rather than being an object; at what point does noise lose its noiseness and become meaning, music, signification? Or -- is there even a point where noise can subsist? Mostly, the text below takes the view that noise is a function of not-noise, itself a function of not being noise. Noise is no more original than music or meaning, and yet its position is to indicate the banished, overcome primordiality, and cannot lose this 'meaning'. Noise, then, is neither the outside of language nor music, nor is it simply categorisable, at some point or other, as belonging exclusively to the world of meaning, understanding, truth and knowledge.

Dirty HC Punk explosion - Bristol scene Rise up + Disorder 9 free CDs
From The Cortinas to Lunatic Fringe and Disorder, Bristol had a huge Punk scene that has influenced, affected and stimulated a vast range of artists that operate in the city. Many of these artists produce music that wouldn’t necessarily suggest a Punk heritage but scratch beneath the surface of a lot of the major players in the Bristol milieu and you will find a fondness for the times of `spikey barnets’, limited musical ability, a `F*** You’ attitude and disrespect for the music industry and its poseur hierarchy.

Leon Theremin /1896-1993/ - the great forefather of Rock N' Roll /big noise master/
In 1919, in the midst of the Russian Civil War, Theremin invented the musical instrument that bears his name. The theremin is an electronic device that resonates sound when its operator waves his hands near its two antennas. It was the first musical instrument designed to be played without being touched. He invented the theremin (also called the thereminvox) in 1919, when his country was in the midst of the Russian Civil War. After a lengthy tour of Europe, during which he demonstrated his invention to full audiences, Theremin found his way to the United States. He performed the theremin with the New York Philharmonic in 1928. He patented his invention in 1929 (U.S. Patent 1,661,058 ) and subsequently granted commercial production rights to RCA. In 1938 Theremin was kidnapped in the New York apartment he shared with his American wife (the black ballet dancer, Iavana Williams) by the NKVD (forerunners of the KGB). He was transported back to Russia, and accused of propagating anti-Soviet propaganda by Stalin. Read More ...
Animal Collective
Album: Fall Be Kind + 9 albums free download
By way of decrying a society that left its citizens unbearably restrained, Edith Wharton describes how in New York in the 1870s, women would order dresses from their Paris dressmakers and then leave them in tissue paper at least two years before wearing them in public; the thought of showing them "in advance of the fashion" was unforgivably vulgar. Social life has changed, but cultural life seems just as restricted now – even Animal Collective are held back by trends that seem a couple of years old (and that they helped to invent). When I think back on 2009, I’ll first remember how our impoverished aesthetic generation repeatedly scraped the resin from the cultural trash barrel. Every second person is wearing neon leggings, and the ones who aren’t rock a ‘70s aesthetic, with high-waisted jeans and moccasins. Christmas sweaters are getting impossible to find at the thrift store. Ska revival. Garage rock revival. It never ends. Read More ...
Guapo
Elixirs
For just over 10 years, London's Guapo has been working in the world of avant and progressive rock. The band's past is a bit hard to track with its numerous lineup changes and guest musicians. The most recent change in roster was the resignation of Matthew Thompson, the founding member of Guapo, which occurred just before the release of 2005's Black Oni. The departure of Thompson has left Guapo with percussionist David Smith and multi-instrumentalist Daniel O'Sullivan. Though O'Sullivan is by no means a founding member of the band, but he was essential in honing the sound on Guapo's last two LPs: Five Suns and Black Oni. These two albums have been pivotal in building Guapo's following of fans, so it's hard not to credit O'Sullivan as an asset to the band.... {audio}http://www.neurotrecordings.com/artists/guapo/audio/Guapo-The%20Selenotrope.mp3 {/audio} ...

Cyberwar Hype Intended to Destroy the Open Internet
The biggest threat to the open internet is not Chinese government hackers or greedy anti-net-neutrality ISPs, it’s Michael McConnell, the former director of national intelligence. McConnell’s not dangerous because he knows anything about SQL injection hacks, but because he knows about social engineering. He’s the nice-seeming guy who’s willing and able to use fear-mongering to manipulate the federal bureaucracy for his own ends, while coming off like a straight shooter to those who are not in the know. When he was head of the country’s national intelligence, he scared President Bush with visions of e-doom, prompting the president to sign a comprehensive secret order that unleashed tens of billions of dollars into the military’s black budget so they could start making firewalls and building malware into military equipment.

Dreamachine - stroboscopic flicker device enter you to a hypnagogic state - try it right here in your browser
The dreamachine (or dream machine) is a stroboscopic  flicker device that produces visual stimuli. Artist Brion Gysin and William Burroughs's "systems adviser" Ian Sommerville created the dreamachine after reading William Grey Walter's book, The Living Brain. In its original form, a dreamachine is made from a cylinder with slits cut in the sides. The cylinder is placed on a record turntable and rotated at 78 or 45 revolutions per minute. A light bulb is suspended in the center of the cylinder and the rotation speed allows the light to come out from the holes at a constant frequency of between 8 and 13 pulses per second. This frequency range corresponds to alpha waves, electrical oscillations  normally present in the human brain while relaxing. Read More ...
Japan’s Annual Penis Festival – Celebrates Fertility
KOMAKI, Japan — It's springtime in Japan and that means one thing. Actually, two things. Penis festivals and vagina festivals. It may sound like a sophomoric gag. But these are folk rites going back at least 1,500 years, into Japan's agricultural past. They're held to ensure a good harvest and promote baby-making. Maybe they should hold more such festivals. Japan has one of the world's lowest birthrates (1.37 children per woman), which experts blame on stagnant incomes and changing gender relations. Read More ...

Island of Ghosts: Hashima Island - Japan’s rotting metropolis
Hashima, an island located in Nagasaki Bay, is better known as Warship Island (Gunkanshima). The island was inhabited until the end of the 19th century, when it was discovered that the ground below it held tons of coal. The island soon became a center of a major mining complex owned by Mitsubishi Corporation. As the complex expanded, rock brought out of the shafts was used to artificially expand the island. Seawalls created in this expansion turned Hashima into the monstrous looking Gunkanshima; its artificial appearance makes it looks more like a battleship than an island. Read More ...

Prudishness, excessive formality, and repression, it is popularly assumed, characterized Victorian culture. Read More ...

Ed was as secretive as he was misguided. He never told anyone how he carved and set into place the walls, gates, monoliths, and moon crescents that make up much of his Castle. Some of these blocks weigh as much as 30 tons. Ed often worked at night, by lantern light, so that no one could see him. He used only tools that he fashioned himself from wrecks in an auto junkyard.

Astronomers had found evidence of something that occurred before the (conventional) Big Bang

Our cosmos was "bruised" in collisions with other universes. Now astronomers have found the first evidence of these impacts in the cosmic microwave background. There's something exciting afoot in the world of cosmology. Last month, Roger Penrose at the University of Oxford and Vahe Gurzadyan at Yerevan State University in Armenia announced that they had found patterns of concentric circles in the cosmic microwave background, the echo of the Big Bang.



This, they say, is exactly what you'd expect if the universe were eternally cyclical. By that, they mean that each cycle ends with a big bang that starts the next cycle. In this model, the universe is a kind of cosmic Russian Doll, with all previous universes contained within the current one. That's an extraordinary discovery: evidence of something that occurred before the (conventional) Big Bang.

Today, another group says they've found something else in the echo of the Big Bang. These guys start with a different model of the universe called eternal inflation. In this way of thinking, the universe we see is merely a bubble in a much larger cosmos. This cosmos is filled with other bubbles, all of which are other universes where the laws of physics may be dramatically different to ours.

These bubbles probably had a violent past, jostling together and leaving "cosmic bruises" where they touched. If so, these bruises ought to be visible today in the cosmic microwave background.

Now Stephen Feeney at University College London and a few pals say they've found tentative evidence of this bruising in the form of circular patterns in cosmic microwave background. In fact, they've found four bruises, implying that our universe must have smashed into other bubbles at least four times in the past.

Again, this is an extraordinary result: the first evidence of universes beyond our own.

So, what to make of these discoveries. First, these effects could easily be a trick of the eye. As Feeney and co acknowledge: "it is rather easy to fifind all sorts of statistically unlikely properties in a large dataset like the CMB." That's for sure!

There are precautions statisticians can take to guard against this, which both Feeney and Penrose bring to bear in various ways.

But these are unlikely to settle the argument. In the last few weeks, several groups have confirmed Pernose's finding while others have found no evidence for it. Expect a similar pattern for Feeney's result.

The only way to settle this will be to confirm or refute the findings with better data. As luck would have it, new data is forthcoming thanks to the Planck spacecraft that is currently peering into the cosmic microwave background with more resolution and greater sensitivity than ever.

Cosmologists should have a decent data set to play with in a couple of years or so. When they get it, these circles should either spring into clear view or disappear into noise (rather like the mysterious Mars face that appeared in pictures of the red planet taken by Viking 1 and then disappeared in the higher resolution shots from the Mars Global Surveyor).

Planck should settle the matter; or, with any luck, introduce an even better mystery. In the meantime, there's going to be some fascinating discussion about this data and what it implies about the nature of the Universe. We'll be watching.

Sir Roger Penrose is a prize winning mathematical physicist and Emeritus Rouse Ball Professor of Mathematics at the Mathematical Institute, University of Oxford.

In this talk he discusses that there is much observational evidence to confirm the existence of an enormously hot and dense early stage of the universe—referred to as the Big Bang. A good deal of this evidence comes from a detailed analysis of the cosmic microwave background (CMB), frequently referred to as the flash of the Big Bang, enormously cooled to about 3.7 degrees absolute, by the universes accelerating expansion. But this very detail presents new puzzles of various kinds, one of the most blatant being an apparent paradox in relation to the second law of thermodynamics. The hypothesis of inflationary cosmology has long been argued to explain away some of these puzzles, but it does not resolve some key issues, including that raised by the second law. In this talk, I describe a very different proposal, which posits a succession of universe aeons prior to our own. The expansion of the universe never reverses in this scheme, but the space-time geometry is nevertheless made consistent through a novel geometrical conception. Analysis of the CMB data, obtained from the WMAP satellite, has a tantalizing bearing on these issues.

Concentric circles in WMAP data may provide evidence of violent pre-Big-Bang activity

By V. G. Gurzadyan  and R. Penrose .......................... Abstract Conformal cyclic cosmology (CCC) posits the existence of an aeon preceding our Big Bang B, whose conformal infinity I is identified, conformally, with B, now regarded as a spacelike 3-surface. Black-hole encounters, within bound galactic clusters in that previous aeon, would have the observable effect, in our CMB sky, of families of concentric circles over which the temperature variance is anomalously low, the centre of each such family representing the point of I at which the cluster converges. These centres appear as fairly randomly distributed fixed points in our CMB sky. The analysis of Wilkinson Microwave Background Probe’s (WMAP) cosmic microwave background 7-year maps does indeed reveal such concentric circles, of up to 6σ significance. This is confirmed when the same analysis is applied to BOOMERanG98 data, eliminating the possibility of an instrumental cause for the effects. These observational predictions of CCC would not be easily explained within standard inflationary cosmology.

According to conformal cyclic cosmology (CCC)[1-3], what would normally be regarded as a probable entire history of our universe, starting with its Big Bang and ending with its accelerating de Sitter-like expansion (assuming a positive cosmological constant Λ [4]), is taken to be but one aeon in a (perhaps unending) succession of such aeons, where the conformal 3-surface B representing the big bang of each aeon is regarded as the conformal continuation of the remote future (i.e. conformal infinity I [5,6]) of the previous one. CCC takes there to be no inflationary phase in any aeon, the observational support that inflation enjoys being supposed to be equally supported by the existence of the final exponential expansion occurring in the previous aeon [7].


Here we consider a particularly striking observational implication of CCC which, in a sense, actually allows us ―to see through‖ the big bang into the previous aeon. We discuss our analysis of the Wilkinson Microwave Background Probe’s (WMAP) data in relation to this, finding a clear positive signal, this being confirmed also in BOOMERanG98 data. Finally, we point to difficulties confronting an alternative explanation of such observations within the framework of standard inflationary cosmology.


The clearest observational signal of CCC results from numerous supermassive black-hole encounters occurring within clusters of galaxies in the aeon previous to ours. These encounters should yield huge energy releases in the form of gravitational radiation bursts. From the perspective of our own aeon (see [3]), these would appear not in the form of gravitational waves, but as spherical, largely isotropic, impulsive bursts of energy in the initial material in the universe, which we take to be some primordial form of dark matter, the impulse moving outwards with the speed of light up to our last-scattering surface

The effect of such an energy burst would be to provide an outward kick to this initial material of the early universe. The kick will be much more energetic than the normal local variations in temperature in the early Big Bang. Accordingly, the outward (almost impulsive) burst would have, proportionally, a rather closely uniform intensity over the whole outward-moving sphere, in this material. This sphere is seen as a circle from our present vantage point, as it intersects our past light cone (where account might need to be taken of a certain amount of distortion of this circle due to inhomegeneities in the mass distribution in either aeon). The energy variations over the sphere would be of the order of the general temperature variations that we see in the CMB, at the last scattering surface, but this now sits on the edge of the far larger energy pulse. We do not see this energy pulse directly (although in principle we could, if it headed directly towards us, which could be the case only for a perceived circle of zero radius). What we see would be the scattered radiation as the pulse encounters further material in the early universe. The effect may be compared with what happens when a supernova burst encounters a cloud of gas.


The intensity of this would be a matter of detailed considerations not discussed in this paper. But the key point is that what is seen would represent only a small fraction of the energy in the burst, and its variance over the perceived circle would, in absolute terms, be only some tiny fraction in the initial fluctuation that we see in the CMB overall because of this reduced proportion. Moreover the intensity that we see, in this small fraction, could appear to us as warmer than the average or lower than average, depending on the details. As viewed from the perspective of our present location in space-time, the most immediately distinctive effect on the CMB of this energy burst would be a circular (or annular) region, perhaps slightly distorted, over which the temperature variance would be anomalously low.


A further point, of considerable diagnostic relevance, would be the fact that such events ought to repeat themselves several times, if CCC is correct, with the centre of each circle remaining at almost exactly the same point in the CMB sky. This is to be expected because such black-hole encounters would be likely to occur many times in the entire history of a single supermassive black hole. Moreover, there might be more than one such black hole within the same galactic cluster, and an entire cluster, if it remains bound in its remote future, would converge on a single point of the I of the previous aeon, in the CCC picture, and this would appear as a single point in our CMB sky. That point, therefore, would be the centre of a family of concentric circles of anomalously low variance in its CMB temperature, with fairly randomly different radii. We might expect, in some cases—perhaps on account of an eventually chaotic gravitational dynamics—that the galactic cluster might instead end up as several distinct ultimately bound portions separating from each other according to the exponential expansion of the later phases of this earlier aeon. In such situations, the different portions, if each remains bound, would converge on separate but close points on I. If black-hole encounters occur within each separate portion of the cluster, this would lead to independent (overlapping) families of circles of anomalously low temperature variance, with slightly separated centres. These pictures are implicit in the claimed predictions of CCC [1-3], although not previously fully spelled out, and the existence or otherwise of such concentric rings represents a powerful observational test of CCC.

For our observational analysis, we have used the 7-year W-band (94 GHz) CMB temperature maps obtained by WMAP [9]. The W-band data are the least contaminated by the synchrotron emission of the Galactic disk; also they have the highest angular resolution. To examine the frequency dependence of the results, the V band data (61 GHz) has also been examined, and we find very little difference between the two. We examined10885choices of centre in the CMB full sky maps, which have been scanned with a given step of 1.5°, excluding the region of the Galactic disk |b|<20°. For each choice of centre, the temperature variance was obtained for circles in successively larger concentric rings of thickness of 0.5°, at increasing radii. These revealed the actual appearance of rings of low variance at certain randomly distributed radii.
Fig. 2ab exhibits a sample of W and V-band histograms, the temperature variance in the rings being plotted against their radii for the indicated centre coordinates. It is seen, that although there is some difference, the main structure of the concentric circles of low variance is the same in both bands. For comparison, Fig.2c shows the behaviour of the temperature variance for simulated Gaussian maps for the parameters of the WMAP’s signal; for details on simulated maps, including in the context of non-Gaussianities, see [10-12]. The region of the map corresponding to Fig. 2 in the W band, with indication of the location of low variance circles, is shown in Fig. 3.


Those points in the CMB sky which are centres of circles whose depth (the amount by which its temperature variance is lower than the mean) is at least 15μK are noted, these deviating greatly from the Gaussian expectation with a significance of up to 6σ, i.e. probability 10-7. (The peaks of high variance are of no importance, as these can result from numerous irrelevant effects.) It is found, very remarkably, that all low-depth circles are also centres of other such circles. We note that points which are simultaneously centres of n circles of around that depth would occur, with Gaussian data, only with the far smaller probability of~10-7n.
Although such high significance supports the reality of the effect, we undertook one further test, which was to involve the BOOMERanG98 [13] data for comparison. Fig.4ab exhibits the analysis for the same region for the maps of WMAP and of BOOMERanG’s two independent channels A+B of 150 GHz. The circle of radius 2-3° is clearly visible in both histograms in Fig.4ab, and other features agree as well. For a comparison, we also ran the difference maps A-B, i.e. of noise, which is shown in Fig.4c. This basically eliminates the possibility that instrumental noise in WMAP is somehow responsible for the effect, and it appears to establish the genuine nature of the observed circles.


In order to stress the key point that our concentric low-variance circles are indeed associated with the same (or closely associated) source, we made comparisons between the histograms exhibiting low-variance circles and those for which the central point is moved by one degree upwards, downwards, to the left, or to the right. We find that there is a tendency is for all the major dips to vanish at once, which is the CCC expectation for a galaxy cluster in the previous aeon which remains bound, but there are many instances where with such slight movement some dips disappear while others with somewhat different radii may appear, which is the CCC expectation for a galaxy cluster in the previous aeon which breaks apart into separated parts, a possibility noted above.


We find that in around 30% of cases where there is a 10μK dip, the neighbourhood of the central point itself exhibits a similar low variance in its temperature, as in Fig. 2, but not in Fig. 4. According to CCC, such situations normally arise simply because of the presence of a circle of very tiny radius. Fig. 5 illustrates a case with small circles (up to 4σ), of many radii and one has to wait for the higher angular resolution expected from the Planck data. Such very small circles have no particular importance for the present discussion, but their statistical frequency could have a diagnostic role to play. They can occur in CCC either because the source events are close to I in the conformal picture (i.e. late in the previous aeon’s history) or from a fortuitous geometrical alignment with our past light cone.


In Figure 6, a conformal diagram [3,5,6] of the observational situation under consideration here is depicted, under the assumption that something close to a standard K=0 Friedmann–Lemaître–Robertson–Walker cosmology holds. We use a conformal time-scale t, in which the last scattering surface is taken at t=0 and our present temporal location at t=1. These two considerations fix t uniquely, where light signals are depicted as being at 45° to the vertical throughout the diagram, the spatial geometry of the universe being taken Euclidean. The picture may be thought of as the orthogonal projection of the conformal space-time to the 2-plane containing our present vantage point O and the co-moving world-line v through it, and the point K on the last-scattering surface L which appears to us as the centre of circle c under consideration. The point W is the intersection of v with L and the CMB celestial sphere Σ may be taken to be the intersection of our past light cone with L. Regarding the circle c as lying on Σ, we find that c projects down to a point S on the line KW. The angular diameter of c, in the celestial sky, is the angle 2a subtended at W by the vertical chord JSH of the circle q in the diagram which passes through O and K, with centre W. We find, using simple geometry, that the locus of events in the space-time that could be the sources of bursts of massless radiation which are perceived, at O, as the circle c must all lie on the past branch h of a rectangular hyperbola, characterized by the fact that its asymptotes are light rays in the diagram, its future-most point being H. (The hyperbola h also necessarily passes through the point Q on q which is diametrically opposite to O.)


Geometrical considerations tell us that in view of the large angular radii of some of the circles that are seen (often with α up to around 15-20° for the third or fourth circles), the events which could be source of some of the largest of these circles would have to have occurred no later than around t=-1/3, which would be well before the final stages of the inflationary phase of any inflationary model (although well within the later stages of our previous aeon, in accordance with CCC). It will be seen, therefore, that this picture provides a serious problem for inflationary cosmology, assuming that our events are not in some unforeseen way spurious. In the inflationary picture [14] the onset of inflation, or Big Bang, would be represented, in Fig. 6, by a horizontal line which is extremely far down the picture, having little connection with such hyperbolae h. Although it is still geometrically possible to obtain circles c of small angular radius from events occurring either in the early inflationary phase or near the Big Bang before the inflationary phase takes over, the statistical distribution of observed circle radii would be very different from what we appear to see, this inflationary picture providing relatively far more circles of large radii and extremely few of tiny radii, since the source events would then lead to plane-wave disturbances randomly moving across the CMB celestial sphere Σ. In any case, such explanations would be completely at odds with the standard inflationary philosophy, which would require the effects of all such early hypothetical explosive events to be ironed out by the exponential expansion. Moreover, our finding that such events have a recurrent nature, with successive events producing effects of the same order of magnitude, seems very hard to square with the inflationary point of view. It may be pointed out, however, that exponential expansion does not, in itself exclude recurrent effects of the same order of magnitude. This occurs also in CCC where in the late stages of the previous aeon there is also an exponential expansion which allows for recurrent effects of the same order of magnitude. But for the reasons stated above, to reproduce the effects that we appear to see, within the framework of inflation, one would require a mechanism for producing recurrent explosive events close to the inflationary turn-off point. No such mechanism has ever been seriously contemplated.
