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

Zygmunt Bauman (1925 - 2017) /17-01-17

Percepcja zmienia się w forum dyskusyjne, którego zwyciezcę nazywamy "sobą".
/Maria Anna Potocka, Nowa estetyka, Poznanie rozszerzone, str. 206/17-01-13

education fails to keep pace with technology, the result is inequality
 …  reformers in the Industrial Revolution, heralding state-funded universal schooling
 …  robotics and artificial intelligence call for another education revolution
 …  working lives are so lengthy and so fast-changing
 …  If 21st-century economies are not to create a massive underclass
 …  on-the-job training is shrinking
 …  Self-employment is spreading, leaving more people to take responsibility for their own skills.
 …  Massive open online courses (MOOCs) have veered away from lectures on Plato or black holes in favour of courses that make their students more employable.
 …  “microcredentials” and “nanodegrees” in, say, self-driving cars or the Android operating system
 …  to teach children how to study and think
 …  A focus on “metacognition” /17-01-13

Sotheby’s Solid $295 Million Contemporary Sale
 …  a correction to an overheated market
 …  Cy Twombly, Untitled (New York City), (1968)
 …  postwar and contemporary art
 …  $45-million Mark Rothko
 …  Covered with his trademark looping white scribbles on a slate-gray background, the work recalls his experience as a cryptologist at the Pentagon.
 …  Andy Warhol’s canvas Mao (1972)
 …  Jackson Pollock, Lucio Fontana, Francis Bacon, and Jean-Michel Basquiat.
 …  really good prices for really good things /17-01-13

choice of a life partner is no accident
 …  to marry someone a lot like you. Similar intelligence, similar height, similar body weight.
 …  these preferences are shaping our genomes
 …  a strong statistical correlation between people’s genetic markers for height and the actual height of their partner.
 …  People had actively chosen partners with similar genes to themselves
 …  whether those choices, too, are rooted in DNA. /17-01-12

exotic looped trajectories of light in three-slit experiment
 …  even when only one of the three slits is illuminated /17-01-12

Deep-Learning Machine Listens to Bach, Then Writes Its Own Music in the Same Style
 …  Can you tell the difference between music composed by Bach and by a neural network?
 …  chorale cantata
 …  delicate interplay between harmony and melody
 …  about half the time, these compositions fool human experts into thinking they were actually written by Bach
 …  They begin with 352 chorales composed by Bach and then transpose these to other keys that lie within a predefined vocal range, to give a data set of 2,503 chorales. They use 80 percent of these to train their neural network to recognize Bach harmonies and the rest to validate it.
 …  to study the nature of creativity /17-01-11

Many-moons theory  …  an identity crisis  …  single-impact hypothesis  …  Big Splash  …  the product not of one impact but of at least a dozen—and it isn’t just one moon but an amalgam of the many moons that came before it  …  Our current moon is also undoubtedly our last, or at least the last one that we’ll see. Its orbit is slowly expanding, sending it a couple of inches or so farther from Earth every year /17-01-11

Coming From a Galaxy Far, Far Away  …  extremely powerful radio blast  …  three billion light-years away  …  he early universe  …  what—or perhaps who—is producing them  …  global network of powerful telescopes  …  magnetars  …  death shrieks of stars collapsing into black holes  …  being broadcast by aliens  …  We’re actively monitoring only a tiny, tiny fraction of the sky at any given time.  …  FRB 121102, was repeatedly broadcasting signals.  …  some mechanism that is capable of repetition  …  FRB 121102 wasn’t erupting according to any predictable pattern  …  Gemini optical telescope  …  supermassive black hole  …  The honest answer is that we don't know /17-01-09

Humans are probably not the greatest intelligences in the universe.  …  But even on Earth  …  The world Go, chess, and Jeopardy champions are now all AI.  …  smarter than humans in every respect  …  scientific reasoning and social skills  …  two forms of superhuman intelligence—alien and artificial—may not be so distinct  …  The transition from biological to synthetic intelligence may be a general pattern  …  I prefer the term “postbiological” to “artificial”  …  Our brains evolved for specific environments and are greatly constrained by chemistry and historical contingencies.  …  much faster than traditional biological evolution  …  we already see reasons why synthetic intelligence will outperform us  …  Neurons reach a peak speed of about 200 hertz, compared to gigahertz  …  machines have almost unlimited room for improvement  …  Ray Kurzweil takes an optimistic view of the postbiological phase of evolution, suggesting that humanity will merge with machines, reaching a magnificent technotopia. But Stephen Hawking, Bill Gates, Elon Musk  …  humans could lose control of superintelligent AI  …  the “control problem”  …  A clever machine could bypass safeguards  …  many worry that the control problem is insurmountable  …  Active SETI  …  to claim that we can foresee the computational abilities and energy needs of a civilization millions or even billions of years ahead of our own  …  superintelligent AIs, being self-improving, could quickly morph into an unrecognizable form  …  perhaps it is in dark matter  …  we should not rule out the possibility that the chemical differences also impact other key functions, such as whether silicon gives rise to consciousness  …  whether an information-processing system supports consciousness  …  Silicon-based brain chips are already under development as a treatment for various memory-related conditions, such as Alzheimer’s  …  If, at some point, chips are used in areas of the brain responsible for conscious functions, such as attention and working memory, we could begin to understand whether silicon is a substrate for consciousness.  …  that the only “chip” that works is one that is engineered from biological neurons  …  consciousness engineering  …  it may be more efficient for a self-improving superintelligence to eliminate consciousness  …  Consciousness is correlated with novel learning tasks that require attention and focus. A superintelligence would possess expert-level knowledge in every domain, with rapid-fire computations ranging over vast databases that could include the entire Internet and ultimately encompass an entire galaxy.  …  the most intelligent systems will not be conscious. On cosmological scales, consciousness may be a blip, a momentary flowering of experience before the universe reverts to mindlessness.  …  benevolent species will see fit to create their own AI mindchildren /17-01-05

Mitochondria contain their own DNA  …  mitochondria were once independent single-celled organisms until, more than a billion years ago  …  today’s plants and animals  …  just 37 genes  …  producing certain mitochondrial proteins right where they’re needed helps the cell better regulate energy production  …  mitochondria, with their history as stand-alone cells, are the only ones with their own command center /17-01-02

można wrażeń dotykać precz z ich rozumieniem /Lot nad miastem, Anna Maria Musz, str. 9 / 16-12-31

DNA editing  …  “sculpting evolution” group at M.I.T.  …  fundamentally altering the natural world  …  the new gene will copy itself in every successive generation  …  There has never been a more powerful biological tool  …  complete transparency  …  to eradicate malaria  …  Natural selection is heinously immoral  …  romantic notions of a natural world defined by innocence and harmony  …  by editing a gene, transform a common virus into a biological weapon  …  Ethical choices in medicine are rarely straightforward  …  crispr, however, privileges design over evolution  …  A release anywhere could be a release everywhere.  …  if an edit cannot be corrected it should not be attempted  …  molecular Noah’s Ark  …  a daisy drive, separates the components of any gene drive into discrete parts—a genetic version of a multistage rocket  …  We have engineered the world around us since the beginning of humanity. The real question is not whether we will continue to alter nature for our purposes but how we will do so. /16-12-29

Steven Pinker  …  At many moments of 2016, it seemed the world was falling apart.  …  Or the election of Donald Trump  …  In August, he told me the world is still in a more peaceful period than at any other time in history.  …  Look at history and data, not headlines.  …  the worldwide, decades-long current toward racial tolerance is too strong to be undone by one man  …  As it happens, most global, long-term trends have been positive. /16-12-25

images of black holes are illustrations  …  what our telescopes actually capture  …  because of their strong gravity, black holes tend to be surrounded by other bright matter that makes it hard to see the object itself  …  indirect images of black holes  …  Milky Way galaxy is evidence of a black hole there  …  What they’re hoping to see is the actual shadow, the actual dark region /16-12-25

Quantum Gravity  …  ‘echoes’ of gravitational waves coming from blackhole mergers might be signs of a theory that finally unifies quantum mechanics and general relativity.  …  the Planck scale: the smallest region of space, the shortest span of time  …  ‘atoms’ of space  …  For GR, space is smooth  …  LIGO  …  signs (in the data) of a quantum-gravity effect known simply as an echo  …  statistical significance of 2.9 sigma /16-12-21

Time Travel  …  before the invention of the printing press, .. notions of any sort of temporal dislocation were next to impossible; people saw the future as relatively similar to the past  …  Industrial Revolution—when people could see just how different the world looked from how it had a decade earlier  …  memory is anything but precise .. it plays tricks on us  …  the fallibility of memory isn’t necessarily a quirk or negative side effect of neural wiring but a necessity for being able to imagine the future  …  thinking about the past is absolutely necessary for imagining the future  …  constructive episodic simulation hypothesis  …  Time travel, then, is ultimately—and paradoxically—an exercise in remembering. /16-12-20
