Controversial Quantum Machine Tested by NASA and Google Shows Promise | MIT Technology ... - 0 views

  • artificial-intelligence software.
  • Google says it has proof that a controversial machine it bought in 2013 really can use quantum physics to work through a type of math that’s crucial to artificial intelligence much faster than a conventional computer.
  • “It is a truly disruptive technology that could change how we do everything,” said Rupak Biswas, director of exploration technology at NASA’s Ames Research Center in Mountain View, California.

  • An alternative algorithm is known that could have let the conventional computer be more competitive, or even win, by exploiting what Neven called a “bug” in D-Wave’s design. Neven said the test his group staged is still important because that shortcut won’t be available to regular computers when they compete with future quantum annealers capable of working on larger amounts of data.
  • “For a specific, carefully crafted proof-of-concept problem we achieve a 100-million-fold speed-up,” said Neven.
  • “the world’s first commercial quantum computer.” The computer is installed at NASA’s Ames Research Center in Mountain View, California, and operates on data using a superconducting chip called a quantum annealer.
  • Google is competing with D-Wave to make a quantum annealer that could do useful work.
  • Martinis is also working on quantum hardware that would not be limited to optimization problems, as annealers are.
  • Government and university labs, Microsoft (see “Microsoft’s Quantum Mechanics”), and IBM (see “IBM Shows Off a Quantum Computing Chip”) are also working on that technology.
  • “it may be several years before this research makes a difference to Google products.”

Quantum math makes human irrationality more sensible | Science News - 0 views

  • People often say that quantum physics is weird because it doesn’t seem rational. But of course, if you think about it, quantum physics is actually perfectly rational, if you understand the math. It’s people who typically seem irrational.
  • In fact, some psychologists have spent their careers making fun of people for irrational choices when presented with artificial situations amenable to statistical analysis. Making allowances for sometimes shaky methodology, there really are cases where people make choices that don’t seem to make much sense.
  • In 1929, Bohr noted that quantum physics refuted the view that analyzing brain processes could “reveal a causal chain that formed a unique representation of the emotional mental experience.” But in quantum physics, Bohr emphasized, an observer inevitably interacted with whatever was being observed, so “any attempt to acquire a knowledge of such [mental] processes involves a fundamentally uncontrollable interference with their course.”

  • “If we replace ‘human judgments’ with ‘physical measurements,’” Wang and colleagues write, “and replace ‘cognitive system’ with ‘physical system,’ then these are exactly the same reasons that led physicists to develop quantum theory in the first place.”

Quantum Gravity Loops Back To Ancient Atomic Logic, and The Big Bang Becomes A Big Boun... - 0 views

  • Greeks had the “first true alphabet”: a “universal” writing system that used a few letters to encode the infinite variety of all possible utterances. Similarly, all matter is written in a "language… of atoms."
  • Mysterious “meanings” still surround 100-year-old quantum mechanics equations
  • Their meaning/function/grammar is relational and sequential and word-like. The information encoded in matching sequential text-like compositions matters (DNA—>RNA, letters—>“social cartesian” lexicon).

  • Beyond the grammars of geometry and algebra lies a domain of not math-like but text-like compositions and meanings (of semantics beyond mathematics).
  • 17. Word and world both have grammars that don’t fit our available mathematical rules.
  • 18. Reality is relational, and not entirely objective. Subject and object aren’t separable, they’re entangled, inescapably. “Objective” is always relative to some other system/observer. 
  •  
    I find it very interesting that the author is trying o look at the world from a different perspective than mathematics. He thinks atoms as a language that have grammar and meanings. He thinks mathematical rules cannot fully explain our world because it is too objective. He involves the idea of language to describe how the world is entangled and relational. As we learned in TOK, language is an important AOK that shows human civilization in a very complicated way. Language is flexible, emotional and relational. It gives things meaning as human likes to assign meaning and pattern to things around. The world around us are not just cold fact, we as observers give them meaning to exist. In that sense, the concept of language can better help us depict the world. --Sissi (2/27/2017)

The Unnecessary Conflict Between Evangelicalism and Science - Forbes - 1 views

  • throughout human history, people have generally understood there to be two kinds of truth: logos - the truth of reason, logic, practical experience, and science – and mythos - the stories of the sacred and divine that reveal truths about the world, but not literal truths. They’re the truths revealed by art, prayer, philosophy and religion that represents the symbolic, transcendent meaning in our life.
  • with the success of the Enlightenment, science, and our modern culture, we seem to have discarded the idea of mythos as part of our mainstream culture. As a consequence, there are those of faith who confuse mythos with logos - that is, they read a story or sacred text and interpret what is intended to be a symbolic aspect of spiritual life and treat it literally, as though the story happened historically or happened exactly as described. And in rejecting religious belief, a lot of atheists make the same mistake.
  • understanding distinction between these truths of mythos and logos points the way towards realizing the compatibility of scientific and religious thought. We need them both. They don’t have to be enemies, as they represent different aspects of the human search for truth. You don’t have to believe there’s a God to see wisdom in the Bible, or believe in Brahman to be moved by the poetry of the Vedas. Likewise, you don’t have to give up your belief in God to understand the wonder and complexity of evolution, or delight in the counter-intuitive math of quantum mechanics.

  • “All religions, arts and sciences are branches of the same tree. All these aspirations are directed toward ennobling man’s life, lifting it from the sphere of mere physical existence and leading the individual towards freedom. It is no mere chance that our older universities developed from clerical schools. Both churches and universities — insofar as they live up to their true function — serve the ennoblement of the individual.”
