Cytaty, ostatni miesiąc  (tu są wszystkie, większą czcionką)

Fragment of rat brain simulated in supercomputer  …  The complexity of the model far outstrips the simplicity of what is being captured  …  Simulating the human brain, he says, poses huge computational challenges: whereas the rat-cortex simulation runs a billion calculations every 25 microseconds, a human simulation would require a billion times more than that. /15-10-13

Price carbon  …  cutting global carbon emissions.  …  Climate change is a serious challenge  …  I will if you will  …  A global carbon price  …  in the Alps, villagers have successfully managed shared land for hundreds of years, /15-10-13

mathematics  …  impenetrable proof  …  Shinichi Mochizuki  …  The trouble that he faces in communicating his abstract work to his own discipline mirrors the challenge that mathematicians as a whole often face in communicating their craft to the wider world.  …  The abc conjecture  …  Looking at it, you feel a bit like you might be reading a paper from the future.  …  Edge of reason  …  I do think, based on my knowledge of Mochizuki, that the likelihood that there's interesting or important math in those documents is pretty high /15-10-13

imprecise supercomputers  …  Energy-optimized hybrid computers with a range of processor accuracies will advance modelling in fields from climate change to neuroscience  …  computers would consume about 100 megawatts — the output of a small power station  …  Inexact hybrid computing has the potential to aid modelling of any complex nonlinear multiscale system  …  energy-efficient hybrid computing is indispensable for modelling the brain, and hence for understanding cognition.  …  human creativity arises from a close synergy between low-energy computation (in which the operation of the brain is susceptible to the brain's own thermal noise) and higher-energy determinism (in which the implications of partially random cognitive jumps can be explored algorithmically in localized parts of the brain)  …  human creativity might be a by-product of evolutionary pressures to optimize the use of energy /15-10-06

There is no known physics theory that is true at every scale—there may never be.  …  But if we expect our theories to be complete, that means that before we can have a theory of anything, we would first have to have a theory of everything—a theory that included the effects of all elementary particles we already have discovered, plus all the particles we haven’t yet discovered! That is impractical at best, and impossible at worst.  …  Feynman was wrong to have been disappointed with his own success in maneuvering around these infinities  …  superstring theory .. there is not any evidence that it actually describes the universe we live in.  …  the more we learn about string theory, the more complicated it appears to be  …  early expectations about its universalism may have been optimistic.  …  nature, as Feynman once speculated, could be like an onion, with a huge number of layers.  …  new physics to discover  …  never be a final, universal theory /Krauss/15-10-06

see yourself in a world where only math is real  …  what’s the time?  …  what’s the place?  …  a property of yourself  …  In my book Our Mathematical Universe, I argue that not only spacetime, but indeed our entire external physical reality, is a mathematical structure, which is by definition an abstract, immutable entity existing outside of space and time.  …  our reality is vastly larger than we thought, containing a diverse collection of universes obeying all mathematically possible laws of physics.  …  we too are made of the same kinds of elementary particles  …  we humans don’t yet fully understand what we are.  …  onsciousness can one day be understood as a form of matter, a derivative of the most beautifully complex spacetime structure in our universe. /15-10-05

wiedza o zasadach, jakimi rządzi się metoda naukowa jest w polskim społeczeństwie znikoma. Nie dowiadujemy się o niej w szkole,  …  Nie uczymy jej na studiach,  …  Tzw. popularyzacja nauki w prasie codziennej polega głównie na wyszukiwaniu sensacji i często przypomina propagowanie „naukowej” magii, urągając METODZIE NAUKOWEJ właśnie.  …  chcemy dogonić świat. /Andrzej Białas/Pauza Akademicka 308/15-10-02

surprisingly cold ‘blob’ in the North Atlantic ocean  …  if the circulation is really slowing we need to weigh  …  dramatic melting of Greenland, by injecting large volumes of freshwater into the ocean, may be the cause.  …  human-caused factors  …  All eyes now turn to the scientists doing the hard work of taking direct measurements of the circulation /15-10-01

Sweden is shifting to a 6-hour work day  …  We want to spend more time with our families, we want to learn new things or exercise more.  …  less staff conflicts because people are happier  …  Sweden - which btw is also making moves to become the world's first fossil fuel-free nation /15-10-01

Gene-edited 'micropigs' to be sold as pets at Chinese institute  …  more serious research  …  an unexpected byproduct — tiny pigs  …  micropigs as models for human disease  …  about 15 kilograms when mature  …  US$1,600  …  gene editing taking biology by storm  …  dogs or cats will be next  …  ethicists agree that gene-edited pets are not very different from conventional breeding /15-10-01

Kotarbiński był wprawdzie powszechnie szanowany w cza- sie swego długiego życia, ale bywało i odwrotnie. W 1943 ro- ku 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 pia- stował, 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 komu- nizmu. Jego ateizm i antyklerykalizm sprawiły, że kilka szkół przestało go uważać za patrona po roku 1989, ale niektóre ( w Andrychowie, Dzierżoniowie, Olsztynie) oparły się tej tendencji. Biblioteka Uniwersytetu Warszawskiego ma w swym hallu cztery posągi filozofów (Twardowskiego, Tar- skiego, Leśniewskiego, Łukasiewicza), ale zabrakło miejsca dla Kotarbińskiego – jak wieść niesie właśnie z powodów światopoglądowych. Kotarbiński umarł w Laskach pod War- szawą. Tuż przed jego śmiercią przystanął ksiądz przy łóżku i wyciągnął rękę do chorego. Kotarbiński ją uściskał, a du- chowny 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 oce- na 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

Social sciences and humanities faculties 'to close' in Japan  …  serve areas that better meet society’s needs  …  linked to a low birth rate and falling numbers of students /15-09-25

Pope John Paul II  …  was a globe-trotter. He introduced the open Popemobile  …  He was the first Pope to visit a synagogue  …  John Paul was probably seen by more people in person than anyone in history.  …  But John Paul probably still left a more profound impression than almost any secular politician of his era. And the new guy seems headed down the same track. /New Yorker/15-09-22

licence to edit genes in human embryos  …  fundamental insights into early human development  …  CRISPR/Cas9  …  to eradicate a genetic disease  …  the UK could serve as a model for other countries  …  that is not going to be implanted into a woman, and which will be destroyed after a few days of culture /15-09-21

Homo naledi .. a mosaic species  …  suggests that nature was experimenting with how to evolve humans, .. a shockingly teleological view  …  If it hadn’t been for the human ego, taxonomists would long ago have squeezed all hominoids into a single genus.  …  The problem is that we keep assuming that there is a point at which we became human.  …  a miraculous spark — that made us radically different.  …  We simply don’t know if Homo naledi buried corpses with care  …  We are trying way too hard to deny that we are modified apes.  …  Why not seize this moment to overcome our anthropocentrism  …  /15-09-18

Deep Learning Machine Teaches Itself Chess  …  by evaluating the board rather than using brute force to work out every possible move.  …  the top 2.2 percent of tournament chess players.  …  neural network .. faster computers .. massive annotated datasets to train the networks.  …  now routinely outperform humans in pattern recognition tasks such as face recognition  …  randomly choosing five million positions from a database of computer chess games. .. then created greater variety by adding a random legal move to each position  …  played against itself with the goal of improving its prediction /15-09-18

Richard Dawkins: Brief Candle in the Dark  …  The Selfish Gene .. genes, not organisms, were the targets of natural selection.  …  for evolution, against design in nature,  …  the 'new atheism', a fundamentalist sect that has mounted a scientistic crusade against all religion.  …  Dawkins has a quantitative turn of mind, but is better at algorithms than theorems. So indeed is life itself, which is why biology has so few laws.  …  Today's genome is much more than a script .. Many researchers continue to find selfish DNA a productive idea, but taking the longer view, the selfish gene per se is looking increasingly like a twentieth-century construct.  …  For a time, Dawkins was a rebellious scientific rock star. Now, his critique of religion seems cranky, and his immovably genocentric universe is parochial. /15-09-18

Letter from the Vatican  …  A determined Pope Francis moves to reform a recalcitrant Curia. ... during the final years of his papacy, when, suffering from Parkinson’s disease, he was severely incapacitated, many things went wrong. ... John Paul II, a century later, with his doctrinal orthodoxy and demands of strict obedience to the Pope. ... “Every Pope is different,” he said. “Every Pope reflects his own time and is the right Pope for that particular time. And so the Church adapts. This is the secret to its survival over two thousand years, with the help of the Holy Spirit.” /Alexander Stille/15-09-14

Bóg bez znaczenia ... oświeceniowi deiści i agnostycy, obawiający się, że utrata przez lud wiary w boga mogłaby oznaczać zwolnienie hamulców .. Helena Eilstein, jak wielu nieteistycznych, myślicieli, wskazuje, że taką postawę należy uznać za "moralnie kwestionowalną, niezależnie od tego, czy by się tak czyniło po to, by poskromić «bestię» w człowieku", czy też po to , by chronić ludzi przed rozpaczą egzystencjalną /Janusz A. Majcherek/15-09-14

Me & my brain .. neuroscience's closet dualism ... "double-subject fallacy": treating the brain and the entire person as two independent subjects who can simultaneously occupy divergent psychological states and even have complex interactions with each other-as in "my brain knew before I did." ... the origins of such writing .. its relevance to the debate on legal and moral responsibility. /15-09-14

Descartes' Error ... If the whole brain is doing a job for 'us', then what is left to be the basis of 'we'? ... For thousands of years, humans have been comfortable with the idea that each person's fundamental essence is something other than the body itself /15-09-14
