“There is something else which has the power to awaken us to the truth. It is the works of writers of genius. They give us, in the guise of fiction, something equivalent to the actual density of the real, that density which life offers us every day but which we are unable to grasp because we are amusing ourselves with lies.”

“Now, the velocity of wave propagation can be seen, without the aid of any mathematical analysis, to depend on the elasticity of the medium and its density; for we can see that if a medium is highly elastic the disturbance would be propagated at a great speed.”

“Is not this Medium [æther] much rarer within the dense Bodies of the Sun, Stars, Planets, and Comets, than in the empty celestial Spaces between them? And in passing from them to great distances, doth it not grow denser and denser perpetually, and thereby cause the gravity of those great Bodies towards one another, and of their parts towards the Bodies; every Body endeavouring to go from the denser parts of the Medium towards the rarer? …And though this Increase of density may at great distances be exceeding stow, yet if the elastick force of this Medium be exceeding great, it may suffice to impel Bodies from the denser parts of the Medium towards the rarer, with all that power which we call Gravity. And that the elastic force of this Medium is exceeding great, may be gather'd from the swiftness of its Vibrations.”

“Inflation is a simple idea: imagine that the universe begins in a tiny patch of space dominated by the potential energy of some scalar field, a kind of super-dense dark energy. This causes that patch to expand at a terrifically accelerated rate, smoothing out the density and diluting away any unwanted relics. Eventually the scalar field decays into ordinary matter and radiation, reheating the universe into a conventional Big Bang state, after which things proceed as normal.”

“[W]hen a body has experienced any changes, and when after a certain number of transformations it returns to precisely its original state, that is, to that state considered in respect to density, to temperature, to mode of aggregation—let us suppose, I say, that this body is found to contain the same quantity of heat that it contained at first, or else that the quantities of heat absorbed or set free in these different transformations are exactly compensated. This fact has never been called in question. It was first admitted without reflection, and verified afterwards in many cases by experiments with the calorimeter. To deny it would be to overthrow the whole theory of heat to which it serves as a basis. For the rest, we may say in passing, the main principles on which the theory of heat rests require the most careful examination. Many experimental facts appear almost inexplicable in the present state of this theory.”

“There is the advantage that a small or light bullet has over a heavy one when it comes to wound ballistics. … What it amounts to is the fact that bullets are stabilized to fly through the air, and not through water, or a body, which is approximately the same density as the water. And they are stable as long as they are in the air. When they hit something, they immediately go unstable. … If you are talking about.30-caliber, this might remain stable through a human body. … While a little bullet, being it has a low mass, it senses an instability situation faster and reacts much faster. … this is what makes a little bullet pay off so much in wound ballistics.”

“The result will be points of quiescence—technically known as nodes—where the air's density varies not at all, and no sound is heard. Note the paradox here: either sphere alone creates a sound wave at this point; two spheres together add up to no sound there at all. Two sources can add up to give less than one. This is the essence of destructive interference. (When two sources are giving the same instruction, the resulting vibration bears not twice but four times the energy. This phenomenon, oxymoronically known as constructive interference, may seem puzzling.)”

“Tony Cairo [English abstract sculptor] and I tried to collaborate at several points and it hasn't been successful. As a matter of fact, recently Tony has made sculpture that I have painted. He has to make the sculpture before I can paint it. That means that the form is taking precedence – that the material takes precedence as a form, rather than color establishing the form. It's not going to well but I'm working on it. There's something about color that is so abstract that it is difficult for it to function in conjunction with solid form... Color has properties of weight, density, transparency, and so forth. And when it also has to be compatible with things that have an actual density, a given form, it's very difficult.”

“There were two problems which had to be faced. One was spatial and the other methodological. In the first case I had to do something about relational painting, i. e. the balancing of the various parts of the painting with and against each other. The obvious answer was symmetry – make it the same all over. The question still remained, though, of how to do this in depth. A symmetrical image or configuration symmetrically placed on a open ground is not balanced out in the illusionistic space. The solution I arrived at, and there are probably quite a few, although I only know of one other, color density, forces illusionistic space out of the painting at constant intervals by using a regulated pattern. The remaining problem was simply to find a method of paint application which followed and complemented the design solution. This was done by using the house painters technique and tools.”

You cannot compress dust into solid matter without creating a real serious physical science problem of overcoming the gas laws. The pressure increases, the temperature increases, which drives them out again - it's not going to happen.”

“Greene takes it for granted, and here the great majority of physicists agree with him, that the division of physics into separate theories for large and small objects is unacceptable. … Greene believes that there is an urgent need to find a theory of quantum gravity that applies to large and small objects alike. … As a conservative, I do not agree that a division of physics into separate theories for large and small is unacceptable. … The essence of any theory of quantum gravity is that there exists a particle called the graviton … I looked at various possible ways of detecting gravitons and did not find a single one that worked. Because of the extreme weakness of the gravitational interaction, any putative detector of gravitons has to be extremely massive. If the detector has normal density, most of it is too far from the source of gravitons to be effective, and if it is compressed to a high density around the source it collapses into a black hole. There seems to be a conspiracy of nature to prevent the detector from working.”

The density of population necessary to enable mankind to obtain, in the greatest degree, all the advantages both of co-operation and of social intercourse, has, in all the most populous countries, been attained. If the earth must lose that great portion of its pleasantness which it owes to things that the unlimited increase of wealth and population would extirpate from it, for the mere purpose of enabling it to support a larger but not a better or a happier population, I sincerely hope, for the sake of posterity, that they will be content to be stationary, long before necessity compels them to it..”

“Animals use aggression as a technique for gaining control over necessities… that are scarce or are likely to become so… They intensify their threats and attack with increasing frequency as the population around them grow. As a result the behavior itself induces members of the population to spread out in space, raises the death rate, and lowers the birth rate. In such cases aggression is said to be a "density-dependent factor" in controlling population growth.”

“In the beginning of 1917, two solutions of the field equations for a homogeneous isotropic universe had been found, which I… call the solutions "A" and "B."… at that time only static solutions were looked for. It was thought that the universe must be a stable structure… In one of these solutions (B) the average density was zero, it was empty; the other one (A) had a finite density…. In B, to get the real universe, we should have to put in a few galactic systems, in A we should have to condense the evenly distributed matter into galactic systems. The universe A… has an average density, but no expansion. It is therefore called the static universe. B, on the other hand… expands, and it could only parade in the garb of a static universe because there is nothing in it to show the expansion. B is therefore called the empty universe. Thus we had two approximations : the static universe with matter and without expansion, and the empty one without matter and with expansion. The actual universe… has both matter and expansion… In 1917… the actual value of the density was still entirely unknown, and the expansion had not yet been discovered.”

“There is no direct observational evidence for the curvature [of space], the only directly observed data being the mean density and the expansion, which latter proves that the actual universe corresponds to the non-statical case. It is therefore clear that from the direct data of observation we can derive neither the sign nor that value of the curvature, and the question arises whether it is possible to represent the observed facts without introducing the curvature at all. Historically the term containing the 'cosmological constant λ' was introduced into the field equations in order to enable us to account theoretically for the existence of a finite mean density in a static universe. It now appears that in the dynamical case this end can be reached without the introduction of λ.”

“Novelty is density of connection. … We are in the grip of some kind of an attractor, and when we look back at history, we can have a sense, I think, that we have never been here before. But we are so accustomed to causal thought, that we assume we have been pushed here, pushed here by historical necessity, by bad political decisions, by the vicissitudes of evolution (cultural and otherwise). I don’t think so. I think we have been pulled here, that we are under the aegis of a kind of an attractor. Some people would call it a “destiny”, but what it is is a dream that is pulling us deeper and deeper into the adventure of existential becoming. And faster and faster—that’s the other thing. Deeper and deeper, faster and faster, so that the rate of change that people were accustomed to before the Industrial Revolution, for example—we can barely conceive of such slow-moving, stately, meta-stable societies.

“The "universe" is an hypothesis, like the atom, and must be allowed the freedom to have properties and to do things which would be contradictory and impossible for a finite material structure. What we observe are the stars and nebulae constituting "our neighbourhood." All that goes beyond that, in time or in space, or both, is pure extrapolation. The conclusions derived about the expanding universe depend on the assumed homogeneity and isotropy, i. e. on the hypothesis that the observed finite material density and expansion of our neighbourhood are not local phenomena, but properties of the "universe." It is not inconceivable that this hypothesis may at some future stage of the development of science have to be given up, or modified, or at least differently interpreted.”

“[Imlac continues] "It was never supposed that cogitation is inherent in matter, or that every particle is a thinking being. Yet, if any part of matter be devoid of thought, what part can we suppose to think? Matter can differ from matter only in form, density, bulk, motion, and direction of motion: to which of these, however varied or combined, can consciousness be annexed? To be round or square, to be solid or fluid, to be great or little, to be moved slowly or swiftly one way or another, are modes of material existence, all equally alien from the nature of cogitation. If matter be once without thought, it can only be made to think by some new modification, but all the modifications which it can admit are equally unconnected with cogitative powers."”

But, over the years, true wilderness has become harder to find. m1s58-m3s03”

“It is quite easy to include a weight for empty space in the equations of gravity. Einstein did so in 1917, introducing what came to be known as the cosmological constant into his equations. His motivation was to construct a static model of the universe. To achieve this, he had to introduce a negative mass density for empty space, which just canceled the average positive density due to matter. With zero total density, gravitational forces can be in static equilibrium. Hubble's subsequent discovery of the expansion of the universe, of course, made Einstein's static model universe obsolete. …The fact is that to this day we do not understand in a deep way why the vacuum doesn't weigh, or (to say the same thing in another way) why the cosmological constant vanishes, or (to say it in yet another way) why Einstein's greatest blunder was a mistake.”

“willow of crystal, a poplar of water,
a pillar of fountain by the wind drawn over,
tree that is firmly rooted and that dances,
turning course of a river that goes curving,
advances and retreats, goes roundabout,
arriving forever:
the calm course of a star
or the spring, appearing without urgency,
water behind a stillness of closed eyelids
flowing all night and pouring out prophecies,
a single presence in the procession of waves
wave over wave until all is overlapped,
in a green sovereignty without decline
a bright hallucination of many wings
when they all open at the height of the sky, course of a journey among the densities
of the days of the future and the fateful
brilliance of misery shining like a bird
that petrifies the forest with its singing
and the annunciations of happiness
among the branches which go disappearing,
hours of light even now pecked away by the birds,
omens which even now fly out of my hand, an actual presence like a burst of singing,
like the song of the wind in a burning building,
a long look holding the whole world suspended,
the world with all its seas and all its mountains,
body of light as it is filtered through agate,
the thighs of light, the belly of light, the bays,
the solar rock and the cloud-colored body,
color of day that goes racing and leaping,
the hour glitters and assumes its body,
now the world stands, visible through your body,
and is transparent through your transparency”

“It was early 1932, when Einstein and I both were at the California Institute of Technology in Pasedena, and we just decided to look for a simple relativistic model that agreed reasonably well with the known observational data, namely, the Hubble recession rate and the mean density of matter in the universe. So we took the space curvature to be zero and also the cosmological constant and the pressure term to be zero, and then it follows straightforwardly that the density is proportional to the square of the Hubble constant. It gives a value for the density that is high, but not impossibly high. That's about all there was to it. It was not an important paper, although Einstein apparently thought that it was. He was pleased to have a simple model with no cosmological constant. That's it.”

“By the time I came to England at the age of sixteen I'd seen a great variety of landscapes. I think the English landscape was the only landscape I'd come across which didn't mean anything, particularly the urban landscape. England seemed to be very dull, because I'd been brought up at a much lower latitude — the same latitude as the places which are my real spiritual home as I sometimes think: Los Angeles and Casablanca. I'm sure this is something one perceives — I mean the angle of light, density of light. I'm always much happier in the south — Spain, Greece — than I am anywhere else. The English one, oddly enough, didn't mean anything. I didn't like it, it seemed odd. England was a place that was totally exhausted.”

“Early human beings… filled a special ecological niche: they were carnivorous primates of the African plains. …When agriculture permitted the increase of population density, game was no longer abundant… carnivorism remained a basic dietary impulse, with cultural aftereffects that varied according to the special conditions of the environment in which the society evolved.”

“There exists also another type of galaxy agglomeration. These have diameters between roughly one and ten times those of large clusters, but have much smaller densitities; they are usually irregular, with patchy density variations and no central concentration. The larger and most conspicuous of these agglomerations may contain several clusters, which explains why they have been given the name "superclusters." In their longer dimensions, crossing times exceed the age of the Universe. They are thus unrelaxed. Unrelaxed apperance, together with large size, might be taken as a definition of superclusters.”

“Manhattan is not altogether felicitous for fiction. It is not a city of memory, not a family city, not the capital of America so much as the iconic capital of this century. It is grand and grandiose with its two rivers acting as a border to contain the restless. Its skyscrapers and bleak, rotting tenements are a gift for photographic consumption, but for the fictional imagination the city's inchoate density is a special challenge.”

“The speed and density of computation have been doubling every three years (at the beginning of the twentieth century) to one year (at the end of the twentieth century), regardless of the type of hardware used. …Despite many decades of progress since the first calculating equipment was used in the 1890 census, it was not until the mid-1960s that this phenomenon was even noticed”

Speed

“Accordingly the primordial state of things which I picture is an even distribution of protons and electrons, extremely diffuse and filling all (spherical) space, remaining nearly balanced for an exceedingly long time until its inherent instability prevails. We shall see later that the density of this distribution can be calculated; it was about one proton and electron per litre. There is no hurry for anything to begin to happen. But at last small irregular tendencies accumulate, and evolution gets under way. The first stage is the formation of condensations ultimately to become the galaxies; this, as we have seen, started off an expansion, which then automatically increased in speed until it is now manifested to us in the recession of the spiral nebulae.

As the matter drew closer together in the condensations, the various evolutionary processes followed—evolution of stars, evolution of the more complex elements, evolution of planets and life.”

“We… come to the conclusion… that the actual universe is neither the static nor the empty one. It differs so much from both of these that neither can be used as an appropriate grand scale model. We must thus look for other solutions of the general field-equations. On account of the expansion our solution must necessarily be a non-static one, and it must have a finite density. There is only one possible static solution possessing a finite density, viz. our old friend A, but of non-static solutions with finite density there exists a great variety.”

“No continent is as small and fragmented as Europe. Only Australia is smaller, yet Europe consists of fifty independent nations (including Turkey and the Caucasus, for reasons explained later). Crowded with nations, it is also crowded with people. Europe's population density is 72.5 people per square kilometer. The European Union's density is 112 people per square kilometer. Asia has 86 people per square kilometer. Europe is crowded and fragmented.”

“I read Stein’s Three Lives, Crane’s The Red Badge of Courage, and Dostoevski’s The Possessed, all of which revealed new realms of feeling. But the most important discoveries came when I veered from fiction proper into the field of psychology and sociology. I ran through volumes that bore upon the causes of my conduct and the conduct of my family. I studied tables of figures relating population density to insanity, relating housing to disease, relating school and recreational opportunities to crime, relating various forms of neurotic behavior to environment, relating racial insecurities to the conflicts between whites and blacks… I still had no friends, casual or intimate, and felt the need for none. I had developed a self-sufficiency that kept me distant from others, emotionally and psychologically.”

“The functional regions of the brain which subserve physical agony, the "pain centres", and the mainly limbic substrates of emotion, appear in phylogenetic terms to be remarkably constant in the vertebrate line. The neural pathways involving serotonin, the periaquaductal grey matter, bradykinin, dynorphin, ATP receptors, the major opioid families, substance P etc all existed long before hominids walked the earth. Not merely is the biochemistry of suffering disturbingly similar where not effectively type-identical across a wide spectrum of vertebrate (and even some invertebrate) species. It is at least possible that members of any species whose members have more pain cells exhibiting greater synaptic density than humans sometimes suffer more atrociously than we do, whatever their notional "intelligence."”
