“In the absence of reliable extensional rheology data, we can only point to the fact that when cats are deformed along their principal axis, they tend to relax more easily, suggesting that the extensional time is smaller than the shear time. Transient strain‑hardening can nonetheless occur. Second, because, flows of cats are usually free surface flows, the surface tension between the cat and its surrounding medium can be important and even dominant in the rheology, especially in CATBER (Capillary thinning and breakup extensional rheometer) experiments.” – M. A. Fardin, “On the Rheology of Cats”

“No living creature, not even man, has achieved, in the centre of his sphere, what the bee has achieved in her own; and were some one from another world to descend and ask of the earth the most perfect creation of the logic of life, we should needs have to offer the humble comb of honey.” – Maurice Maeterlinck, The Life of the Bee

“Nature is always magnificent when dealing with the privileges and prerogatives of love. She becomes miserly only when doling out the organs and instruments of labour. She is especially severe on what men have termed virtue, whereas she strews the path of the most uninteresting lovers with innumerable jewels and favours. ‘Unite and multiply; there is no other law, or aim, than love,’ would seem to be her constant cry on all sides, while she mutters to herself, perhaps: ‘and exist afterwards if you can; that is no concern of mine.’ ” – Maurice Maeterlinck, The Life of the Bee

“The most trivial secret of the non-human object we behold in nature connects more closely perhaps with the profound enigma of our origin and our end, than the secret of those of our passions that we study the most eagerly and the most passionately.” – Maurice Maeterlinck, The Life of the Bee

“Verbal nonsense (Ganser syndrome) and physical nonsense (buffoonery syndrome) within the realm of medical science are pathologized conditions. Verbal nonsense (as in vaudeville, joking) and physical nonsense (as in slapstick, clowning) within the realm of entertainment (both on and off the stage) are conditions of art.” – Mady Schutzman, “Being Approximate: The Ganser Syndrome and Beyond”

“Normal humans in all societies manifest a sense of sympathy: an ability to treat the interests of others as comparable to their own. Unfortunately, the size of the moral circle in which sympathy is extended is a free parameter. By default, people sympathize only with members of their own family, clan, or village, and treat anyone outside this circle as less than human. But under certain circumstances the circle can expand to other clans, tribes, races, or even species. An important way to understand moral progress, then, is to specify the triggers that prompt people to expand or contract their moral circles. It has been argued that the circle may be expanded to include people to whom one is bound by networks of reciprocal trade and interdependence, and that it may be contracted to exclude people who are seen in degrading circumstances. In each case, an understanding of nonobvious aspects of human nature reveals possible levers for humane social change.” – Steven Pinker, “Why nature & nurture won’t go away”

“Developmental psychology has shown that infants have a precocious grasp of objects, intentions, numbers, faces, tools, and language. Behavioral genetics has shown that temperament emerges early in life and remains fairly constant throughout the life span, that much of the variation among people within a culture comes from differences in genes, and that in some cases particular genes can be tied to aspects of cognition, language, and personality. Neuroscience has shown that the genome contains a rich tool kit of growth factors, axon guidance molecules, and cell adhesion molecules that help structure the brain during development, as well as mechanisms of plasticity that make learning possible. These discoveries not only have shown that the innate organization of the brain cannot be ignored, but have also helped to reframe our very conception of nature and nurture.” – Steven Pinker, “Why nature & nurture won’t go away”

“Every evening our eyes tell us that the sun sets, while we know that, in fact, the Earth is turning us away from it. Astronomy taught us centuries ago that common sense is not a reliable guide to reality. Today it is neuroscience that is forcing us to readjust our intuitions. People naturally believe in the Ghost in the Machine: that we have bodies made of matter and spirits made of an ethereal something. Yes, people acknowledge that the brain is involved in mental life. But they still think of it as a pocket PC for the soul, managing information at the behest of a ghostly user. Modern neuroscience has shown that there is no user. ‘The soul’ is, in fact, the information-processing activity of the brain. New imaging techniques have tied every thought and emotion to neural activity. And any change to the brain—from strokes, drugs, electricity or surgery—will literally change your mind.” – Steven Pinker, “How to think about the mind”

“Though visible signs of the ability to prevail in a fight are the most salient advertisements of authority, they are not necessarily the qualifications that earned the authority in the first place. Dominance in humans is tied up with status: the possession of assets like talent, beauty, intelligence, skill, and wisdom. And in the end, dominance and status are social constructions that depend crucially on the perception of others and of oneself. How much authority one possesses depends on how much authority one is prepared to claim, and on how much authority others are willing to cede to you.” – Steven Pinker, “The evolutionary social psychology of off-record indirect speech acts”

“In most times, places, and stages of development, people’s abilities in arithmetic consist of the exact quantities ‘one,’ ‘two,’ and ‘many,’ and an ability to estimate larger amounts approximately. Their intuitive physics corresponds to the medieval theory of impetus rather than to Newtonian mechanics (to say nothing of relativity or quantum theory). Their intuitive biology consists of creationism, not evolution, of essentialism, not population genetics, and of vitalism, not mechanistic physiology. Their intuitive psychology is mindbody dualism, not neurobiological reductionism. Their political philosophy is based on kin, clan, tribe, and vendetta, not on the theory of the social contract. Their economics is based on tit-for-tat back-scratching and barter, not on money, interest, rent, and profit. And their morality is a mixture of intuitions of purity, authority, loyalty, conformity, and reciprocity, not the generalized notions of fairness and justice that we identify with moral reasoning.” – Steven Pinker, “The cognitive niche: Coevolution of intelligence, sociality, and language”

“I had always been impressed by the fact that there are a surprising number of individuals who never use their minds if they can avoid it, and an equal number who do use their minds, but in an amazingly stupid way. I was also surprised to find many intelligent and wide awake people who lived (as far as one could make out) as if they had never learned to use their sense organs: They did not see the things before their eyes, hear the words sounding in their ears, or notice the things they touched or tasted. Some lived without being aware of the state of their own bodies. There were others who seemed to live in a most curious condition of consciousness, as if the state they had arrived at today were final, with no possibility of change, or as if the world and the psyche were static and would remain so forever. They seemed devoid of all imagination, and they entirely and exclusively depended upon their sense-perception. Chances and possibilities did not exist in their world, and in ‘today’ there was no real ‘tomorrow.’ The future was just the repetition of the past.” – Carl G. Jung, “Approaching the unconsciousness”

“The attitude of modern civilized man sometimes reminds me of a psychotic patient in my clinic who was himself a doctor. One morning I asked him how he was. He replied that he had had a wonderful night disinfecting the whole of heaven with mercuric chloride, but that in the course of this thoroughgoing sanitary process he had found no trace of God.” – Carl G.

“The two fundamental points in dealing with dreams are these: First, the dream should be treated as a fact, about which one must make no previous assumption except that it somehow makes sense; and second, the dream is a specific expression of the unconscious.” – Carl G.

“The main problem facing any kind of studies on solifuges is the keeping of these animals in captivity. So far, nobody has successfully reared them in a laboratory. It is even difficult to keep them a short time (e.g., two weeks) in captivity. Most of the Namibian species died after a couple of days after they had been captured. The Argentinean species survived a maximum of about two weeks in captivity. The eremobatid species, captured in Arizona (USA) survived in general for about a week. The galeodid species from Kazakhstan survived a slightly longer period up to a couple of months, which could implicate, that these animals are less susceptive regarding e.g., differences in temperature. All solifuges independent the country where they were collected became lethargic after a couple of days and did not show any kind of a natural behavior any more.” – Anja Elisabeth Klann, Histology and Ultrastructure of Solifuges

“As one passes through the levels of incarceration—from the minimum to the moderate to the maximum security institutions, and then to the solitary confinement section of these institutions—one does not pass deeper and deeper into a subpopulation of the most ruthlessly calculating criminals. Instead, ironically and tragically, one comes full circle back to those who are emotionally fragile and, often, severely mentally ill.” – Stuart Grassian, “Psychiatric Effects of Solitary Confinement”

“One of saddest lessons in history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even to ourselves, that we’ve been taken.” – Carl Sagan, The Demon Haunted World

“Should a mouse that a cat just swallowed be considered as a part of the cat? The concept of a ‘definite position’ is also only approximately defined: how far should a cat be displaced in order for it to be considered to be in a different position? If the displacement is much smaller than the quantum uncertainty, it must be considered to be in the same place, because in this case the quantum state of the cat is almost the same and the displacement is undetectable in principle. But this is only an absolute bound, because our ability to distinguish various locations of the cat is far from this quantum limit. Furthermore, the state of an object (e.g. alive or dead) is meaningful only if the object is considered for a period of time.” – Lev Vaidman, “Many-Worlds Interpretation of Quantum Mechanics”

“A glass is a nonequilibrium state of matter between that of a solid and a liquid. It is a non-crystalline amorphous solid that has a nanoscopically and microscopically disordered structure but many of the mechanical properties of a solid. Glass is a nonequilibrium, non-crystalline state of matter that appears solid on a short time scale but continuously relaxes towards the liquid state . . . . a nonequilibrium, non-crystalline condensed state of matter that exhibits a glass transition. The structure of glasses is similar to that of their parent supercooled liquids, and they spontaneously relax toward the supercooled liquid state. Their ultimate fate, in the limit of infinite time, is to crystallize. In the glassy state, the viscosity is exceptionally high, conformational changes are severely inhibited, and the material is metastably trapped in a solid but microscopically disordered state. A glass is rigid and brittle.” – Martin Chaplin, Water Structure and Science (internal quotes and citations omitted)

“Solid ice is stable to over 200 GPa and 4400 K in a body-centered cubic structure, near the melt boundary in water-rich Neptune-like planets. This may be responsible for the increased electrical conductivity that may promote the generation of multipolar magnetic fields. Due to the fluidity of the protons in Ice XVIII, and in contrast to the low-pressure ices, this ice is likely to be black. The oxygen ions form a close-packed structure with 12 nearest neighbors to each side, filling 74% of the space. This ice may be considered as a new state of matter, solid and liquid, at the same time, similar to a metallic structure but with free protons rather than electrons. It has been suggested that suitable conditions for Ice XVIII lie deep inside the watery giants Uranus and Neptune and may be common throughout the Universe.” – Martin Chaplin, Water Structure and Science

“Although the cosmological constant cold dark matter model is very successful in explaining almost all observations, it has some theoretical issues within its backbone structure. These include the mysterious physical origin of the two largest contributions to the energy content of the late-time Universe: cold dark matter and the cosmological constant, together with the unsatisfactory predictability and test-ability of the inflation theory. Therefore, it is important to explore alternative explanations for the late-time acceleration of the Universe. There have been several proposals . . . hints remain from the Dark Energy Survey and several previous galaxy surveys that the Universe today is a few percent less clumpy than predicted. . . . On the other hand, massive binary black holes as standard sirens have the disadvantage that the redshift needs to be measured independently of the gravitational wave observations. If we identify the host galaxy then it should be possible to determine with joint events whether long-wavelength gravitational wave and short-wavelength electromagnetic radiation have the same number of spacetime dimensions. . . . Also, there have been studies considering the propagation from the inspiraling of compact binary systems within the context of teleparallel gravity theories . . . meanwhile it is important to mention that these studies are in the context of a scenario where the general relativity cosmological model is considered as an effective fluid in the standard perturbations equations.” – Sebastian Bahamonde, et al., “Teleparallel Gravity: From Theory to Cosmology”

“Although representations of traumatic events (such as flashbulb memories) are not wholly immune to error and distortion, evidence suggests that negative and stressful experiences lead to a reduction of the structural plasticity. This may support the idea that the normal function of memory is to form constructive, plastic memories since, in cases of traumatic memories, the memory system as a whole loses plasticity and is, as a result, far less efficient. If our memories would not be modified according to the present or prospective future, a discrepancy would emerge. If memories were to represent the past exactly, representation of the past would not let us absorb changes. Since the present itself is in perpetual change, the memory of the past must have the same dynamic nature.” – Tzofit Ofengenden, “Memory Formation and Belief”

“The fact that episodic memory is fragmentary and fragile suggests that its adaptiveness may derive less from its role as an accurate record of personal history than from providing a ‘vocabulary’ from which to construct planned future events (and perhaps to embellish events of the past). It may be part of a more general toolbox that allowed us to escape from the present and develop foresight, and perhaps create a sense of personal identity. Indeed, our ability to revisit the past may be only a design feature of our ability to conceive of the future.” – Thomas Suddendorf and Michael Corballis, “The evolution of foresight: what is mental time travel, and is it unique to humans?”

“Memory is not only about the past, but is also about the future. Indeed, while memory serves as the ability to recall previous experiences, recall itself is not solely directed toward the past, but is guided by the present for the service of the future.” – Tzofit Ofengenden, “Memory Formation and Belief”
