math can teach us about finding order in our chaotic lives
… we search for a pattern that eliminates some of the chaos.
… if there were a computer that would simply calculate the Kolmogorov complexity of any string? .. computer tools like AI, deep learning, big data, quantum computing, etc., it would be easy to create such a computer.
… the Kolmogorov complexity of a string cannot be computed.
… While a computer might find some pattern in a string, it cannot find the best pattern.
… We will simply never know if the pattern that we have found is the best one.
… But that makes the search eternally interesting. .. something is interesting if it demands more thought.
… We want to know that there is some meaning, purpose, and significance in the world around us.
… We are biologically programmed to find some patterns that explain what they see.
… Really good literature .. leaves us with the possibility of many interpretations. We come face to face with the incomputability of the Kolmogorov complexity. /18-09-02
The End of Theoretical Physics
… That we are able to write down natural laws in mathematical form at all means that the laws we deal with are simple — much simpler than those of other scientific disciplines.
… actually solving those equations is often not so simple.
… not from more sophisticated math but from more computing power.
… quantum behavior of space and time itself
… a quantum simulation to study so-called spin networks, structures that, in some theories, constitute the fundamental fabric of space-time.
… to simulate the information processing of black holes with ultracold atom gases.
… This line of research raises some big questions. First of all, if we can simulate what we now believe to be fundamental by using composite quasiparticles, then maybe what we currently think of as fundamental — space and time and the 25 particles that make up the Standard Model of particle physics — is made up of an underlying structure, too.
… With quantum simulations, the mathematical model is of secondary relevance.
… experimentalists will just learn which system maps to which other system /18-08-31

… A long stringy molecule found a way to copy itself.
… tiniest increments generation after generation .. mutations .. to be stronger, faster, fly
… this process has led one particular organism – us – to grow large brains
… to shrink evolutionary time .. to manipulate the blind stumblings of random mutations
… Humans had advanced so far that we were finally able to control our own evolution.

… CRISPR might do more than make yogurt cheaper
… Eventually, a CRISPR baby will be born. The technology is too easy. There is no world government to stop its use; many argue no one should do so anyway. At the point that baby emerges, perhaps modified to evade a particular disease or perhaps even to look a particular way, theoretical debates will become real.
… Every week a new paper is published finding more genes that influence looks, intelligence, stamina, even sexuality.

… observed the Lyman-alpha electronic transition in the antihydrogen atom
… Finding any slight difference between the behaviour of antimatter and matter would rock the foundations of the Standard Model of particle physics and perhaps cast light on why the universe is made up almost entirely of matter, even though equal amounts of antimatter should have been produced in the Big Bang.

evolutionary psychological science
… Darwin’s ideas to issues of behavior, stood up, smiled at the rain, and pushed forward.
… The evolutionary perspective allows you to think about any and all psychological phenomena in a broader perspective.
… Humans are disgusted by stimuli that have the capacity to decrease the probability of survival and/or reproductive success.
… Obesity and resultant health issues such as cardiac disease are largely the result of an evolutionary mismatch between ancestral food offerings compared with modern, highly unnatural food offerings
… Large-scale politics are a mess partly because the human mind only evolved to deal with small-scale politics
… The evolutionary perspective has cracked the code on love in humans
… evolutionary psychology is a superpower. /18-08-29

Democracy” means that they people rule, while “liberal” (in this sense) means that the rights of individuals are protected, even if they’re not part of the majority. Recent years have seen the rise of an authoritarian/populist political movement in many Western democracies, one that scapegoats minorities in the name of the true “will of the people.”
… liberal democracy could ultimately fail even in as stable a country as the United States.

The idea of free information is extremely dangerous
… Yuval Noah Harari
… the long-term past of humankind and the long-term future
… we are heading towards a full-scale arms race of artificial intelligence, which is very, very bad news.
… Liberalism is based on the assumption that you have privileged access to your own inner world of feelings and thoughts and choices, and nobody outside you can really understand you. This is why your feelings are the highest authority in your life and also in politics and economics – the voter knows best, the customer is always right. Even though neuroscience shows us that there is no such thing as free will, in practical terms it made sense because nobody could understand and manipulate your innermost feelings. But now the merger of biotech and infotech in neuroscience and the ability to gather enormous amounts of data on each individual and process them effectively means we are very close to the point where an external system can understand your feelings better than you. We’ve already seen a glimpse of it in the last epidemic of fake news.
… The more people believe in free will, that their feelings represent some mystical spiritual capacity, the easier it is to manipulate them
… There is no penalty for creating a sensational story that is not true.

Unreality of the Quantum World
… Wheeler .. elementary quantum phenomena are not real until observed .. anti-realism.
… Mach-Zehnder interferometer
… The Delayed-Choice Experiment
… to avoid retro-causality is to deny the photon any intrinsic reality and argue that the photon becomes real only upon measurement.
… Causal modeling involves establishing cause-and-effect relationships between various elements of an experiment.
… A hidden variable, in this context, is something that’s absent from standard quantum mechanics but that influences the photon’s behavior in some way.
… the first phase shift can take one of three values, and the second one of two values. That makes six possible experimental settings
… all three showed that the formula is greater than zero with irrefutable statistical significance. They ruled out the classical causal models of the kind that can explain Wheeler’s delayed-choice experiment.
… the most popular hidden variable theory remains unaffected by these experiments. The de Broglie-Bohm theory, a deterministic and realistic alternative to standard quantum mechanics, is perfectly capable of explaining the delayed-choice experiment. In this theory, particles always have positions (which are the hidden variables), and hence have objective reality, but they are guided by a wave. So reality is both wave and particle.

Is Poland Retreating from Democracy?
… A debate about the country’s past has revealed sharply divergent views of its future.
… Elisabeth Zerofsky
… up to three years in prison for any false claim that “the Polish Nation or the Republic of Poland is responsible or co-responsible for Nazi crimes committed by the Third Reich.”
… Anna Azari, said that the law could be seen as criminalizing Holocaust survivors
… There were no Polish units working under the Waffen S.S., as was the case with Dutch, Norwegian, and Estonian units.
… Warsaw suffered like no other European capital during the war.
… Catherine the Great, wrote that Poland was the home of “chaos,” “barbarity,” and “fanaticism.” For hundreds of years, Poland’s German and Russian neighbors had depicted Poland as backward and unenlightened, deserving of invasion.
… A few days after my meeting with Nowak, I looked up Comey’s speech. Nowak is a careful speaker, so I was surprised to find that what he’d told me wasn’t entirely true. In his address, Comey said that he asked every F.B.I. special agent he hired to visit the Holocaust Museum, in order to understand the human propensity for moral surrender. “In their minds,” Comey said, “the murderers and accomplices of Germany, and Poland, and Hungary, and so many, many other places, didn’t do something evil. They convinced themselves it was the right thing to do.”
… In the summer of 2017, the sociologist Maciej Gdula interviewed Law and Justice supporters from a provincial town not far from Warsaw, many of whom had benefitted greatly from the economic boom. Still, they felt despised by Polish élites. Kaczyński, they thought, offered a vision in which “you no longer have to go to university, get a mortgage and buy a flat, and declare that you have ‘European values,’ in order to be a fully-fledged member of the Polish nation,” as one reviewer of Gdula’s book, “The New Authoritarianism,” put it.
… Kaczyński said that accepting refugees would “completely change our culture and radically lower the level of safety in our country.” That year, however, Poland took in the second-highest number of immigrants in the E.U., mostly from Ukraine.
… Kaczyński rarely speaks to foreign media.
… Jarosław has never married, and lived with his mother until her death, in 2013. Now he lives with his cats. He opened a bank account for the first time in 2009, does not have a driver’s license, and prefers to eat alone. A person who knows Kaczyński told me that, since the death of his brother, he has acted without the check on his decisions that Lech used to provide.
… Kaczyński’s relationship with Rydzyk is strategic
… Adam Michnik .. most influential liberal newspaper, Gazeta Wyborcza, told me that he worried about a “creeping coup d’état that is transforming Poland into a Putinist-type state.”
… the percentage of people who think that Poles suffered as much as Jews during the war rose from thirty-nine in 1992 to sixty-two in 2012.
… “Hate speech is more and more accepted by this government,” Suchanow told me. A few weeks after the Cursed Soldiers demonstration, neo-Nazis marched through Warsaw, some wearing the S.S. insignia, which is illegal in Poland; the police protected them against far-left counterprotesters.

… the algorithm changes the parameters of its [predictive] model in such a way that next time, when it encounters the same situation, it will be less surprised
… The predictions then get sent down as feedback to lower-level sensory regions of the brain.

Thomas Bayes and the crisis in science
… Footnotes to Plato

… Statisticians increasingly rely on Bayesian logic. Even our email spam filters work on Bayesian principles.
… It is only over the past couple of decades that the tide has turned. //for example: AW, 1983//
… This states that the probability of A given B equals the probability of B given A, times the probability of A, divided by the probability of B.
… The focus of his paper is not his theorem, which appears only in passing, but the logic of learning from evidence.
… initial probabilities to the hypotheses
… “prior probabilities” are not always available
… instead they cooked up the idea of “significance tests”. Don’t worry about prior probabilities, they said. Just reject your hypothesis if you observe results that would be very unlikely if it were true.
… Fisherians .. Neyman-Pearsonians
… the normally recommended level was 5 per cent
… In truth, this is nonsense on stilts. One of the great scandals of modern intellectual life is the way generations of statistics students have been indoctrinated into the farrago of significance testing.
… Science is currently said to be suffering a “replicability crisis”.
… “the Bayesian brain”
… unsurprisingly, many mainstream university statistics departments are still unready
… Some defenders of the old regime have suggested that the remedy is to “raise the significance level” from 5 per cent to, say, 0.1 per cent

A shift from the ascetic to the aesthetic is underway. At its center: evolutionary biology.
… a couple of papers on obscure subjects that nobody cares about, and, at the age of sixty, be ugly and respected and a full professor
… Female academics face a double bind: Look attractive and you seem unserious; look homely and you seem dour.
… abstract, formal sciences, dedicated largely to the elucidation of pattern and structure, celebrate a beauty that is cool and impersonal: fractals and spheres; the crystalline arrangement of atoms; the possibility of symmetry in the fundamental forms of matter
… This bloodless, geometric notion of beauty faces a new challenge from within the sciences. Recent evolutionary-biological inquiry into beauty is, like physics, awed by the power of the aesthetic. But new scholarship brings a messier, and sexier, form of beauty into view.

… Rola nauczania na uczelniach – podobnie jak całego systemu edukacji – powinna ulec gruntownej zmianie. Zmiana ta jest i będzie wymuszana poprzez rewolucję cywilizacyjną ostatnich kilkunastu lat, prawdziwie schumpeterowską, kreatywną destrukcję większości naszych kulturowych obyczajów, reguł działania itp. Obszarem naszej cywilizacji, w której ta kreatywna destrukcja napotyka zaciekły opór starych struktur, jest edukacja wszystkich szczebli, niemogąca pogodzić się z konsekwencjami zanurzenia społeczeństw w oceanie powszechnie i w zasadzie bezpłatnie dostępnej informacji, zgromadzonej i zarządzanej przez przepoczwarzający się permanentnie twór, potocznie zwany światowym Internetem.
Struktura tego dostępu do informacji, jak na razie, niestety, nie dyskryminuje fałszu i kłamstwa wobec prawdy. Konsekwencją tego jest konieczność zmiany głównych akcentów procesu edukacji z dostarczania wiedzy na dostarczanie zdolności odróżnienia prawdy od fałszu. Uwzględnienie tego w procesie kształcenia w szkołach powszechnych, przygotowujących studentów naszych uczelni wyższych, zostało w zasadzie zignorowane w przeprowadzanej obecnie reformie szkolnej. Dlatego nauczanie na uniwersytetach, szczególnie w pierwszych trzech latach (do licencjatu), powinno być podporządkowane dwóm warunkom: nauczaniu odróżnienia prawdy od kłamstwa – szczególnie tego ukrytego w todze paranaukowego bełkotu – oraz nadrobieniu zaległości edukacyjnych ze szkoły średniej. W fizyce oznacza to przywrócenie zasadniczej roli doświadczeniu laboratoryjnemu (niemal nieistniejącemu w obecnej szkole powszechnej) oraz zbliżenie poznawanej fizyki do fizyki-nauki, tworzącej dzisiaj nasz postęp cywilizacyjny. /18-05-28

evolution is more complex than we once assumed
… extended evolutionary synthesis (EES)
… whether what happens to organisms during their lifetime – their development – can play important and previously unanticipated roles in evolution.
… The way that genes are expressed to produce an organism’s phenotype – the actual characteristics it ends up with – is affected by chemicals that attach to them.
… Usually these so-called ‘epigenetic’ attachments are removed during the production of sperm and eggs cells, but it turns out that some escape the resetting process and are passed on to the next generation
… truly Lamarckian
… epigenetic inheritance pushes us to think about evolution in a different way
… social learning in mammals, birds, fish and insects

It might be true.

Consciousness as a State of Matter
… “perceptronium”, with distinctive information processing abilities
… quantum factorization problem: why do conscious observers like us perceive the particular Hilbert space factorization corresponding to classical space (rather than Fourier space, say)
… Our approach generalizes Giulio Tononi’s integrated information framework for neural-network-based consciousness to arbitrary quantum systems, and we find interesting links to error-correcting codes, condensed matter criticality, and the Quantum Darwinism program, as well as an interesting connection between the emergence of consciousness and the emergence of time.
… it is striking that many of the most hotly debated issues in physics today involve the notions of observations and observers .. these issues have resisted resolution for so long is .. what constitutes an observer
… Is our persistent failure to unify general relativity with quantum mechanics linked to the different roles of observers in the two theories? .. observer in general relativity has no mass, no spatial extent and no effect on what is observed, whereas the quantum observer notoriously does appear to affect the quantum state of the observed system
… One might hope that a detailed observer definition will prove unnecessary because some simple properties such as the ability to record information might suffice
… Another commonly held view is that consciousness is unrelated to quantum mechanics because the brain is a wet, warm system where decoherence destroys quantum superpositions of neuron firing much faster than we can think, preventing our brain from acting as a quantum computer .. consciousness and quantum mechanics are nonetheless related, but in a different way: it is not so much that quantum mechanics is relevant to the brain, as the other way around. Specifically, consciousness is relevant to solving an open problem at the very heart of quantum mechanics: the quantum factorization problem.
… David Chalmers has termed “the hard problem” of consciousness
… non-physical element such as an “anima” or “soul”. Support for dualism among scientists has gradually dwindled with the realization that we are made of quarks and electrons
… Occam’s razor
… an arrangement of particles can feel conscious, we will start with the hard fact that some arrangement of particles (such as your brain) do feel conscious while others (such as your pillow) do not, and ask what properties of the particle arrangement make the difference.
… Giulio Tononi .. for an information processing system to be conscious, it needs to have two separate traits:
1. Information: It has to have a large repertoire of accessible states, i.e., the ability to store a large amount of information.
2. Integration: This information must be integrated into a unified whole, i.e., it must be impossible to decompose the system into nearly independent parts, because otherwise these parts would subjectively feel like two separate conscious entities. .. Integrated Information Theory (IIT)
… neural correlates of consciousness .. physical correlates of consciousness
… the future of artificial intelligence to determining when an animal, fetus or unresponsive patient can feel pain
… Principle - Definition:
Information principle - A conscious system has substantial information storage capacity.
Dynamics principle - A conscious system has substantial information processing capacity.
Independence principle - A conscious system has substantial independence from the rest of the world.
Integration principle - A conscious system cannot consist of nearly independent parts.
Autonomy principle - A conscious system has substantial dynamics and independence.
Utility principle - An evolved conscious system records mainly information that is useful for it.
… the information principle: by applying the Schrodinger equation to systems that could record and store information, he (Hugh Everet) inferred that they would perceive subjective randomness in accordance with the Born rule. /18-01-02

… The statistic is used to test a ‘null hypothesis’, a default state positing that there is no relationship between the phenomena being measured. The smaller the P value, the less likely it is that the results are due to chance — presuming that the null hypothesis is true. Results have typically been deemed ‘statistically significant’ — and the null hypothesis dismissed — when P values are below 0.05.
… this threshold should be reduced to 0.005
… researchers should select and justify P value thresholds for their experiments, before collecting any data

… selecting for males who allow females autonomy and choice.
… catalog of Things Natural Selection Can’t Explain but Sexual Selection Easily Can includes homosexuality, a tendency toward monogamy, both sex’s taste and capacity for sex outside of female fertility periods
… When sex offers orgasm at relatively low pregnancy risk, it provides a way not just to reproduce but to assess potential mates’ attention to female desires, tastes and choices.
… This is why beauty should not be seen as merely the stamp of quality assurance that conventional evolutionary theory thinks it is. Beauty, rather, forms the foundation of an entire, complex evolutionary dynamic — one that can influence how we treat each other. /17-09-23
… Examining the science and supernaturalism of Buddhism
… it is helpful and therapeutic
… practicing Vipassana, or “insight” meditation
… Buddha is conceived as a wise man and self-help psychologist, not as a divine being
… This nimble-footed doubleness may indeed hold profound existential truths
… The sitter becomes less selfish and more selfless.
… Buddhist doctrine and practice anticipate and affirm the “modular” view of the mind favored by much contemporary cognitive science. Instead of there being a single, consistent Cartesian self that monitors the world and makes decisions, we live in a kind of nineties-era Liberia of the mind, populated by warring independent armies implanted by evolution, representing themselves as a unified nation but unable to reconcile their differences, and, as one after another wins a brief battle for the capital, providing only the temporary illusion of control and decision.
… the fixed self is an illusion imprinted by experience
… Meditation .. is not a metaphysical route toward a higher plane.
… Whether or not evolutionary psychology is a real or a pseudoscience—opinions vary
… Christianity try to tiptoe past the doctrines of Heaven and Hell, so that Hell becomes “the experience of being unable to love,” or Heaven a state of “being one with God”
… why a scientific explanation of that kind has seldom arisen in Buddhist cultures.
… meditation practice—the draining away of the stories we tell compulsively about each moment in favor of simply having the moment
… Can any old faith point a new way forward?
… A faith practice with an authoritarian structure sooner or later becomes a horror; a faith practice without an authoritarian structure sooner or later becomes a hobby. /17-09-13

Odds for Lucky Mutations
… SOS response, a DNA repair mechanism that bacteria employ when their genomes are damaged, during which dozens of genes become active and the rate of mutation goes up. Those extra mutations are more often detrimental than beneficial, but they enable adaptations
… Is the upsurge in mutations merely a secondary consequence of a repair process inherently prone to error? Or, .. is the increase in the mutation rate itself an evolved adaptation
… harsh environments cause nonrandom mutations
… It has also been to find a plausible mechanism consistent with the rest of molecular biology that could make lucky mutations more likely.
… more mutation specifically in regions of the yeast genome where it could be most adaptive
… are mutations always random?
… variation in the number of gene copies might be a response to stresses or hazards in the environment

From Bacteria to Bach and Back
… For Dennett this apparent irreducibility – philosophers call it “the hard problem” – is a false distinction.
… Consciousness is a system property, and is not reducible: he takes issue with those hard-line molecular biologists, notably DNA pioneer Francis Crick, who seek to locate consciousness in particular ensembles of neurons in specific brain regions. Such ensembles, Dennett argues, are mini-robots, competent in their functions, but only their interactions within the totality of the brain enable comprehension, and with it the “user illusion” that we all share, of being a person in charge of these processes.
… Here, his principal target is Chomsky, who has always insisted on the uniqueness and universality of human language. As Chomsky points out, language is unlike any other evolved human feature.
… the origins of language lie in the social nature of humans and come from the necessity of communicating
… Memes are, for Dennett, units of cultural transmission.

… The initial impact would dig a hole 20 miles deep, and 120 miles across. Deep rock would rise as high as the Himalayas, and then collapse to form the observed impact ring, all within 10 minutes. The impact fireball would kill everything within a 600 mile radius. A shock wave would spread out through the solid earth, and a monstrous tsunami through the oceans. The atmosphere would have seen hurricane force winds, and rock condensing in the upper atmosphere would produce a rain of tiny glass spheres

… parenting influences — are all secondary when it comes to personality, behaviour or intelligence
… Steven Pinker .. ‘A cosmic ray mutates a stretch of DNA, a neurotransmitter zigs instead of zags, the growth cone of an axon goes left instead of right, and one identical twin’s brain might gel into a slightly different configuration from the other’s.’ In other words, we should not presume that random chance plays a vanishingly small role in making us the people that we are today.
… We may not hold their tomorrows in our hands but we surely hold their todays
… Pinker, meanwhile, makes the point that it should be enough for us to remember that our children are human beings, worthy of the same ethical treatment we give to our friends, other relatives, and even to strangers. So protect your children, provide for them, be good to them, and make memories with them. Apart from that, don’t expect to have very much say in how they turn out. /17-06-18

Daniel Dennett’s naturalistic account of consciousness
Four billion years ago, Earth was a lifeless place. Nothing struggled, thought, or wanted. Slowly, that changed. Seawater leached chemicals from rocks; near thermal vents, those chemicals jostled and combined. Some hit upon the trick of making copies of themselves that, in turn, made more copies. The replicating chains were caught in oily bubbles, which protected them and made replication easier; eventually, they began to venture out into the open sea. A new level of order had been achieved on Earth. Life had begun.
The tree of life grew, its branches stretching toward complexity. Organisms developed systems, subsystems, and sub-subsystems, layered in ever-deepening regression. They used these systems to anticipate their future and to change it. When they looked within, some found that they had selves—constellations of memories, ideas, and purposes that emerged from the systems inside. They experienced being alive and had thoughts about that experience. They developed language and used it to know themselves; they began to ask how they had been made.
… His newest book, “From Bacteria to Bach and Back,” tells us, “There is a winding path leading through a jungle of science and philosophy, from the initial bland assumption that we people are physical objects, obeying the laws of physics, to an understanding of our conscious minds.”

Sean Carroll, The Big Picture: On the Origins of Life, Meaning, and the Universe Itself
Our goal is to offer plausibility sketch that the world can ultimately be understood on the basis of naturalism. We don't know how life began, or how consciousness works, but we can argue that there's little or no reason to look beyond the natural world for the right explanations. We can always be wrong in that belief; but then again, we can always be wrong about any belief.
… science is precluded from making statements about supernatural forces because these are outside its provenance. Not really. Science should be interested in determining the truth, whatever that truth may be- natural, supernatural or otherwise.
Is it possible that God exists, and communicates with human beings in ways that circumvent our ordinary senses? Absolutely. As Plantinga correctly points out, if theism is true,
… two competing propositions: one is that God Exists,
… the other is naturalism, which would explain such experiences the same way it would explain dreams or hallucinations or other impressions
… To decide between them, we need to see which one coheres better with other things we believe about the world.
Given the profound and deeply personal nature of prayer, meditation, and contemplation, it can seem frivolous or diminishing to relate them to psychedelics or the activity of neurons, or even to dispassionate scientific investigation of any sort. But if we wont to undertake our journey to the best possible understanding of the world with the intellectual honesty it deserves, we always have to question our beliefs, consider alternatives, and compare them with the best evidence we can gather. It may be the case that transcendent experiences arise from a direct connection with a higher level of reality, but the only way to know is to weight that idea against what we learn from the world by looking at it.

Philosophy Lost Its Way

2) formalists who provided the logical undergirding for research across the academy;
3) translators who brought the insights of the academy to the world at large;
4) disciplinary specialists who focused on distinctively philosophical problems in ethics, epistemology, aesthetics and the like; or
5) as some combination of some or all of these.
… Philosophy adopted the scientific modus operandi of knowledge production, but failed to match the sciences in terms of making progress in describing the world.
… to match the cognitive success of the sciences
… We, too, produce research articles. We, too, are judged by the same coin of the realm: peer-reviewed products. We, too, develop sub-specializations far from the comprehension of the person on the street. In all of these ways we are so very “scientific.”

… a Philosopher ought to be something greater and better than another man
… There was a brief window when philosophy could have replaced religion as the glue of society; but the moment passed. People stopped listening as philosophers focused on debates among themselves.

Im dalej w las, tym szerzej się otwiera
Jeśli jakieś zwątpienie, to wiatr je rozwiewa.

i wyjaśnia ochoczo tajemnice światów.
W prawo jaskinia, w której leży sens.
W lewo jezioro Głębokiego Przekonania.
Z dna odrywa się prawda i lekko na wierzch wypływa.
Góruje nad doliną Pewność Niewzruszona.

a widoczne po brzegach drobne ślady stóp
bez wyjątku zwrócone są w kierunku morza.
Jak gdyby tylko odchodzono stąd
i bezpowrotnie zanurzano się w topieli.

The dark universe
… Scientists have theories about dark matter and dark energy — and some observations — but both are poorly understood
1. Is there a dark-matter particle?
… Subatomic dark-matter particles, analogous to the particles that make up the visible Universe, would fit nicely into current physics models
… Weakly interacting massive particles (WIMPs) are the leading candidates
2. Does dark matter interact with anything?
… the only known effect is gravitational pull
… dark matter seems to interact with other dark matter
… for signs of dark matter interacting with ordinary matter
3. Does the cosmological constant explain dark energy?
… The simplest explanation for dark energy is that there is a small force that acts in opposition to gravity
… theory says that it is 10120 greater than that, a Universe-sized discrepancy

how mind arises from matter or how, in turn, mind acts on the brain
… there is no nonphysical soul or ego, or at least no evidence for that
… consciousness is a kind of con game the brain plays with itself
… The brain is a computer that evolved to simulate the outside world. Among its internal models is a simulation of itself — a crude approximation of its own neurological processes. The result is an illusion. Instead of neurons and synapses, we sense a ghostly presence — a self — inside the head. But it’s all just data processing. “The machine mistakenly thinks it has magic inside it,” Dr. Graziano said. And it calls the magic consciousness.
… There is a gap in the explanation where suddenly a miracle seems to occur.
… For lack of a precise mechanism describing how minds are generated by brains, some philosophers and scientists have been driven back to the centuries-old doctrine of panpsychism — the idea that consciousness is universal, existing as some kind of mind stuff inside molecules and atoms.
… Consciousness doesn’t have to emerge. It’s built into matter, perhaps as some kind of quantum mechanical effect.
… perceptronium: atoms arranged so they can process information and give rise to subjectivity

Wszystko, co istnieje w poznanym dotychczas świecie,zbudowane jest z tych samych elementów fizycznych – atomów – wspólnych dla organizmów żywych i materii nieożywionej. Teza o powstaniu zjawiska życia poprzez jednorazowy akt twórczy nie jest akceptowana przez fizykę. Sądzimy, że życie od około 4 miliardów lat rozwijało się z atomów poprzez formowanie, a następnie przez interakcje prostych cząsteczek chemicznych i makrocząsteczek. W procesie ewolucji powstawało coraz więcej „części”, a relacje między nimi stawały się coraz bardziej złożone. W wyniku tych procesów powstały złożone systemy biologiczne.

Kotarbiński był wprawdzie powszechnie szanowany w czasie swego długiego życia, ale bywało i odwrotnie. W 1943 roku został umieszczony na liście osób przeznaczonych do likwidacji, sporządzonej przez radykalną prawicę. Powodem był jego (umiarkowany) liberalizm lewicowy i filosemityzm. Był też ceniony w PRL, o czym świadczą stanowiska, jakie piastował, i odznaczenia, jakie mu przyznano. Kotarbiński bywał (i nadal tak jest) krytykowany za zbytnią uległość wobec władz PRL. Zupełnie niesłusznie, gdyż jego postawa współpracy wypływała z realizmu praktycznego, a nie sympatii do komunizmu. Jego ateizm i antyklerykalizm sprawiły, że kilka szkół przestało go uważać za patrona po roku 1989, ale niektóre (m.in. w Andrychowie, Dzierżoniowie, Olsztynie) oparły się tej tendencji. Biblioteka Uniwersytetu Warszawskiego ma w swym hallu cztery posągi filozofów (Twardowskiego, Tarskiego, Leśniewskiego, Łukasiewicza), ale zabrakło miejsca dla Kotarbińskiego – jak wieść niesie właśnie z powodów światopoglądowych. Kotarbiński umarł w Laskach pod Warszawą. Tuż przed jego śmiercią przystanął ksiądz przy łóżku i wyciągnął rękę do chorego. Kotarbiński ją uściskał, a duchowny ogłosił potem publicznie, że filozof w ten sposób wyspowiadał się i przyjął ostatnie sakramenty. Przytaczam te fakty nie dla sensacji, ale ku przestrodze. Oto biografia i ocena jednego z wielkich współczesnych Polaków bywają ma- nipulowane gwoli doraźnych potrzeb politycznych. Dotyczy to kogoś, kto całym swoim życiem zaświadczał o respektowania moralnych imponderabiliów. Jan Woleński, Pauza Akademicka 307/15-09-25

Steven Pinker, Writing In The 21st Century
You're casting your bread onto the waters, hoping that this invisible and unknowable audience will catch your drift.
... The first step to being a good writer is to be a good reader: to read a lot, and to savor and reverse-engineer good prose ...
But language has always been a grassroots, bottom-up phenomenon. ...
it's hard to imagine what it's like not to know something that you do know.
... biological phenomena were explained in part at the level of molecules, which were explained by chemistry, which was explained by physics. There's no reason that that this process of explanation can't continue. Biology gives us a grasp of the brain, and human nature is a product of the organization of the brain, and societies unfold as they do because they consist of brains interacting with other brains and negotiating arrangements to coordinate their behavior, and so on. Now I know that there is tremendous resistance to this idea, because it's confused with a boogeyman called reductionism ...
A program of unifying the arts and humanities with the psychological sciences and ultimately the biological sciences promises tremendous increases of depth of understanding for all the fields.
It's becoming increasingly clear over the decades and centuries that an understanding of science is central to our understanding of the deepest questions of who we are, where we came from, what matters. /14-06-11
