"A less inflexible picture of mathematics is one that focuses on the fact that it is an open-ended human activity. Inventionism is the belief that mathematics is nothing more than what mathematicians do. ...We invent mathematics; we do not discover it. ...The independent discovery of the same mathematical theorems by different mathematicians from totally different economic, cultural, and political backgrounds—often at widely separated times in history—argues against such a simple view. The inventionist could respond by pointing to the universality of human languages. ...One might expect that those aspects of this universal grammar that share features of logic, and hence counting, would also make counting appear instinctive. In fact, although simple counting... is fairly universal in ancient and primitive cultures, virtually none of them went on to carry out mathematical operations more sophisticated than counting. This suggests that these higher mathematical operations are not genetically programmed into the human brain... They are more likely to be by-products of multi-purpose pattern-recognition capabilities."

"If musical appreciation is a by-product of a more general pattern-processing propensity of the brain, then why are our senses heightened by pink noises? It is significant that the world around us is full of variations with 1/f spectra. Benoit Mandelbrot has pioneered the study of natural and computer-generated patterns that are scale-free. (He calls them fractals...) Mandelbrot draws attention to the fact that there is a pattern to the noise spectrum displayed by the human nervous system. At the extremities of the body... it tends to be of white-noise form; but, as one approaches closer to the central nervous system and the brain, these variations become 1/f-like. Our nervous system may act as a spectral filter to prevent the brain from being swamped with uninteresting white background noise about the world..."

"Actually philosophical speculations have led to a great deal of good science. Einstein’s musings on Mach’s principle played a key role in developing general relativity. Einstein’s debate with Bohr and the EPR paper have led to a great of deal of good physics testing the foundations of quantum physics. My own examination of the Copernican principle in cosmology has led to exploration of some great observational tests of spatial homogeneity that have turned an untested philosophical assumption into a testable – and indeed tested - scientific hypothesis. That’ s good science."

"Life, like science and art, is a theory about the world: a theory that in our case takes bodily form. By a succession of adaptations, most of which are favourable and none of which are lethal, living things have invested in particular expectations about the future course of their environments. If those theories are good enough, then life will prosper and multiply; but if they are outmoded by changing conditions, their embodiments will dwindle and perish."

"The laws of Nature are based upon the existence of a pattern, linking one state of affairs to another; and where there is pattern, there is symmetry. Yet...the symmetries that the laws enshrine are broken in... outcomes. Suppose that we balance a needle on its point and then release it. The law of gravity, which governs its subsequent motion, is perfectly democratic. It has no preference for any particular direction in the Universe: it is symmetrical in this respect. Yet, when the needle falls, it must fall in a particular direction. The directional symmetry of the underlying law is broken, therefore... By the same token, the fallen needle hides the symmetry of the law... Such 'symmetry-breaking' governs much of what we see in the Universe... It allows a Universe governed by a small number of symmetrical laws to manifest an infinite diversity of complex, asymmetrical states. This is how the Universe can be at once, simple and complicated."

"Attempts to explain values in terms of neuroscience or evolutionary theory in fact have nothing whatever to say about what is good or bad. That is a philosophical or religious question (scientists trying to explain ethics from these kinds of approaches always surreptitiously introduce some unexamined concept of what is a good life by the back door)."

"Hundreds of years ago, natural theologians tried to impress their readers with stories of the wondrous symmetries of Nature; now we see that, ironically, it is the departures from those symmetries that makes life possible. It is upon the flaws of Nature, not the laws of Nature, that the possibility of our existence hinges. ...The laws and constants of Nature are features that enforce uniformity and simplicity, while initial conditions and symmetry breakings permit complexity and diversity."

"Above all he believes that these mathematically based speculations solve thousand year old philosophical conundrums, without seriously engaging those philosophical issues. The belief that all of reality can be fully comprehended in terms of physics and the equations of physics is a fantasy."

"The Universe has imposed aspects of its structure upon us by the inevitability of the forces of Nature... In a world where adapters succeed, but non-adapters fail, one expects to find vestigial remnants... Many of these adaptations... give rise to a suite of curious byproducts, some of which have played a role in determining our aesthetic sense. We are products of a past world where sensitivities to certain things were a matter of life or death."

"You cannot do physics or cosmology without an assumed philosophical basis. You can choose not to think about that basis: it will still be there as an unexamined foundation of what you do."

"The various creation stories of ancient time were not scientific theories in any modern sense. They did not attempt to reveal anything new about the structures of the world; they aimed simply to remove the specter of the unknown from human imaginings."

"The Indian religious traditions... accepted the concept of non-being on an equal footing with that of being. Like many other Eastern religions, the Indian culture regarded Nothing as a state from which one might have come and to which one might return.. Where Western religious traditions sought to flee from nothingness... a state of non-being was something to be actively sought by Buddhist and Hindus in order to achieve Nirvana: oneness with the Cosmos."

"Fludd's apology for the Brotherhood of the Rosy Cross was first issued in 1616, being printed in Leyden. It "entitles him to be regarded as the high priest of their mysteries." It is said that Maier visited Fludd in London in 1615, and the result of his visit was, we know, the publication of his 'Apologia,' written in Latin, and published in Leyden in 1616."

"Geomancy was a natural art, drawing on the inborn powers of the human soul to glean information from the larger soul of the world."

"At the beginning of the 17th century many learned heads in England were occupied with Theosophy, Cabbalism, and Alchemy: amongst the proofs of this... may be cited the works of , of Norbert, of Thomas and Samuel Norton, but above all (in reference to our present inquiry) of Robert Fludd. Fludd it was, or whosoever was the author of the Summum Bonum 1629, that must be considered as the immediate father of Freemasonry, as Andrea was its remote father. What was the particular occasion of his own first acquaintance with , is not recorded: all the books of Alchemy or other occult knowledge, published in Germany, were at that time immediately carried over to England — provided they were written in Latin; and, if written in German, were soon translated for the benefit of English students. He may therefore have gained his knowledge immediately from the three Rosicrucian books. But it is more probable that he acquired his knowledge on this head from his friend Maier (mentioned in the preceding chapter) who was intimate with Fludd during his stay in England, and corresponded with him after he left it. At all events he must have been initiated into Rosicrucianism at an early period, having published his apology for it in the year 1617."

"THE central figure of Rosicrucian literature, towering as an intellectual giant above the crowd of souffleurs, theosophists, and charlatanic professors of the magnum opus, who, directly or otherwise, were connected with the mysterious Brotherhood, is Robertus de Fluctibus, the great English mystical philosopher of the seventeenth century, a man of immense erudition, of exalted mind, and, to judge by his writings, of extreme personal sanctity. Ennemoser describes him as one of the most distinguished disciples of Paracelsus, but refuses to number him with "those consecrated theosophists who draw all wisdom from the fountain of eternal light." He does not state his reasons for this depreciatory judgment, and the brief and inadequate notice which he gives of Fludd's system displays such a cursory acquaintance with the works in which it is developed, that it is doubtful whether he had taken pains to understand his author."

"But absolutely nothing remains of that one and only medicament of which Hippocrates makes mention (darkly and mystically, I admit) in several places, and still less are its operations understood, inasmuch as no one now searches with lynx-like eyes into the profound depths of true natural philosophy, to gain an accurate knowledge of its composition and its virtues."

"Which of us has, at this day, the ability to discover those true and vivific numbers whereby the elements are united and bound to one another?"

"But, good God, what is this when compared with that deep and true music of the wise, whereby the proportions of natural things are investigated, the harmonical concord and the qualities of the whole world are revealed, by which also connected things are bound together, peace established between conflicting elements, and whereby each star is perpetually suspended in its appointed place by its weight and strength, and by the harmony of its lucent spirit"

"The art, also, of alchemy or chemistry is surrounded with such insoluble enigmas that we can scarcely gain anything but ignorance therefrom, and ignotum per ignotius."

"Particulars are frequently fallible, but universals never. Occult philosophy lays bare Nature in her complete nakedness, and alone contemplates the wisdom of universals by the eyes of intelligence. Accustomed to partake of the rivers which flow from the Fountain of Life, it is unacquainted with grossness and with clouded waters."

"The existence of dark matter particles can never be disproven by direct experiment because ever lighter particles and/or ever smaller cross sections just below the current detection threshold may be postulated for every non-detection. There exists no falsifiable prediction concerning the DM particles."

"Galaxies are observed to be simple systems following laws that result from scale-invariant dynamics which do not emanate from the haphazard merging history of halos of exotic dark matter."

"The existence of exotic dark matter particles outside the standard model of particle physics constitutes a central hypothesis of the current standard model of cosmology (SMoC). Using a wide range of observational data I outline why this hypothesis cannot be correct for the real Universe."

"The current standard model of cosmology (SMoC) requires The Dual Dwarf Galaxy Theorem to be true according to which two types of dwarf galaxies must exist … The Dual Dwarf Galaxy Theorem is falsified by observation and dynamically relevant cold or warm DM cannot exist. It is shown that the SMoC is incompatible with a large set of other extragalactic observations."

"The currently (2010) widely accepted/believed description of the birth and evolution of the universe and of its contents is "Lambda Cold Dark Matter Concordance Cosmological Model" (LCDM CCM) … My own research was very much confined to the early version of the LCDM CCM (mid-1990's) when I began performing numerical experiments on the satellite galaxies of the Milky Way. I was quite happy with the CCM, as everyone else, and did not bother with the fundamental issues raised by some. With time, however, it became apparent that the LCDM CCM accounts poorly for the properties of the satellite galaxies and their distribution about the Milky Way. Warm dark matter models fared no better."

"For me MOND is just as nonstandard as ΛCDM."

"The first step is that we need to revisit the validity of Newton’s universal law of gravitation. Starting in the 1980s, Mordehai Milgrom at the Weizmann Institute in Israel showed that a small generalisation of Newton’s laws can yield the observed dynamics of matter in galaxies and in galaxy clusters without dark matter. This approach is broadly known as MOND (MOdified Newtonian Dynamics). Milgrom’s correction allows gravitational attraction to fall off with distance more slowly than expected (rather than falling off with the square of distance as per Newton) when the local gravitational acceleration falls below an extremely low threshold. This threshold could be linked to other cosmological properties such as the ‘dark energy’ that accounts for the accelerating expansion of the Universe.These links suggest a deeper fundamental theory of space, time and matter, which has not yet been formulated."

"MOND works far too well! In fact, just as planetary systems are Keplerian objects, galaxies are Milgromian objects. Milgrom’s discovery of a0 is likely as epochal as Planck’s discovery of h."

"... I was deeply shocked when it was not my predictions or any of my immediate colleagues' predictions that came true in my data — but Milgrom's. This was completely outside my conceptual framework."

"A long time ago when I first got interested in MOND, having come from the background where I believed in dark matter, I wrote a proposal saying, "Gee, this theory had its predictions come true, ... we should look into that" and it was rejected, you know, very harshly. And I thought "OK, the community is not willing to fund this kind of thing" — this was almost twenty years ago. And so I basically did a global substitute, replaced MOND with dark matter, resubmitted, and I got my money. ... Pavel is totally correct that scientists are focused on getting grants, because that's what you need to support your students, and your postdocs, and getting the data, and all those sort of things. And I would like to believe that that was an anecdote from the distant past, but I am aware of a colleague who had this experience very recently where this person did not even mention MOND in the proposal, but the panel came back saying "MOND is no good — you must not spend money on this." ... the panel had associated ... this person's name with having at some point written a paper about MOND and projected that onto this proposal that ... did not mention MOND. And so it really is that bad."

"Whenever I come across a case that doesn't make sense in MOND, it usually doesn't make sense in either."

"Why does MOND get any predictions right? It has had many a priori predictions come true. Why does this happen?"

"... Dark matter provides the additional gravitational pull to bring model and reality broadly into alignment. Researchers now routinely take this model – Einstein plus dark matter, often called the ‘null hypothesis’ – as their starting point and then perform detailed calculations of galactic systems to test it. ... Most recently, Stacy McGaugh at Case Western Reserve University in Ohio and his team documented that the pattern of rotation in spiral galaxies seems to precisely follow the pattern of the visible matter alone, posing yet another challenge to the null hypothesis."

"People have been looking for this dark matter because there is a Nobel prize, for sure, waiting for whoever discovers it."

"Community Reactions: "You are un-hireable" My (counter)Reaction: 1) "There is something not quite right with the community" 2) "Once one leaves the dark matter framework, real and correct predictions become possible""

"I have experienced time and again people dismissing the data because they think MOND is wrong, so I am very consciously drawing a red line between the theory and the data."

"One should not only be truthful, but as complete as possible. It does not suffice to be truthful while leaving unpleasant or unpopular facts unsaid."

"A long standing prediction (Milgrom 1983) of MOND is that rotating galaxy curves will fall on a single mass-velocity relation with slope 4: Mb \propto Vf4. This prediction is realized in multiple independent data sets. Gas rich galaxies fall where predicted by MOND with no free parameters. There are not many predictions in extragalactic astronomy that fare so well a quarter century after their publication. … a physical understanding for why galaxy formation in the context of ΛCDM should pick out the particular phenomenology predicted a priori by MOND remains wanting."

"The current cosmological paradigm, the cold dark matter model with a cosmological constant, requires that the mass-energy of the Universe be dominated by invisible components: dark matter and dark energy. An alternative to these dark components is that the law of gravity be modified on the relevant scales. A test of these ideas is provided by the baryonic Tully-Fisher relation (BTFR), an empirical relation between the observed mass of a galaxy and its rotation velocity. Here, I report a test using gas rich galaxies for which both axes of the BTFR can be measured independently of the theories being tested and without the systematic uncertainty in stellar mass that affects the same test with star dominated spirals. The data fall precisely where predicted a priori by the modified Newtonian dynamics."

"I came to the subject a True Believer in dark matter, but it was MOND that nailed the predictions for the LSB galaxies that I was studying (McGaugh & de Blok, 1998), not any flavor of dark matter. So what I am supposed to conclude?"

"Obvious results provoke opposition. The more obvious the result, the stronger the opposition."

"It is often stated that the evidence for is overwhelming. This is not quite correct: the evidence for mass discrepancies is overwhelming. These might be attributed to either dark matter or a modification of gravity."

"... It was (in part) Gross’s excessive enthusiasm for string theory in the mid-80s that drove me (as an impressionable grad student at Princeton) away from theoretical physics (and into astronomy). String theory may have been a beautiful idea, but it made no predictions that could be tested experimentally in the then-foreseeable future. That’s not science. A quarter century later and the theoretical physics community has yet to wake up and realize that there is new physics right under their noses – just not the new physics they’ve been expecting (GUTs, strings, membranes, etc.). Galaxy dynamics are consistent with a single, universal force law, but this unexpected behavior has largely been ignored because it doesn’t fit with particle theorists’ dreams of super symmetric dark matter particles. That we do not understand the observed behavior makes it more interesting than the “expected” (but unobserved) new physics: who ordered this?"

"My gut reaction to all these questions is negative. But it appears that one set or the other must be answered in the affirmative. Either way, we are missing something fundamental about the nature of our universe."
