Steve Wozniak maintained for a long time that true AI is relegated to the realm of science fiction. But recent advances in quantum computing have him reconsidering his stance.Here is Here's How You Can Help Build a Quantum Computer:
Quantum computers—theoretical machines which can process certain large and difficult problems exponentially faster than classical computers—have been a mainstay of science fiction for decades. But actually building one has proven incredibly challenging.These would be some big advances in a field that has spent $100M just to discover that 15 = 3x5.
A group of researchers at Aarhus University believes the secret to creating a quantum computer lies in understanding human cognition. So, they've built computer games to study us, first. ...
To build a quantum computer, researchers are first mapping human thoughts.
Peter Woit is back online, reporting more physics hype. He quotes Weinberg:
I am not a proponent of the idea that our Big Bang universe is just part of a larger multiverse.Once other planets, stars, and galaxies were named, we had to have names for our planet, sun, and galaxy. I don't know the history, but I am guessing that it took a while for a term like "our Milky Way galaxy" to catch on.
So now we have the term "our Big Bang universe" to distinguish our universe from all the other universes. None of those other universes have names, as they cannot be observed. But we can name our universe, and cosmologists seem to be moving away from the idea that "universe" means everything.
The term "our Big Bang universe" suggests that it includes Earth and everything we see going back to the Big Bang, and everything emanating forward in time, but nothing before the Big Bang, and nothing that is so separated from us that relativity precludes any interaction with us.
