  1. Re:Ethanol is just stupid on The Great Ethanol Scam · · Score: 1

    The fact that diesel has a higher energy content is only part of the equation. One of the main reasons that diesel engines are so efficient is that they can run with a fully open throttle almost all the time so you have hardly any throttle losses. They are the main reason why a gas engine is inefficient at low power since you have to maintain the mix and can't go arbitrarily lean as a diesel can.

  6. Re:Consciousness - right track / wrong track on Towards Artificial Consciousness · · Score: 1

    Of course the "temporal resolution" of thoughts depends on what else is going on in the brain. It can be several seconds if we're distracted.
    And as to what dreams deposit in our memories I don't even want to speculate. That's too close to theology for my taste.

  7. Re:Consciousness - right track / wrong track on Towards Artificial Consciousness · · Score: 1

    I didn't say that. There are plenty of researchers looking into how the brain and neurons works. But as long as they don't have more results it's futile to speculate, unless you want to venture into metaphysics or sci-fi. That's OK, but it's not science.
    Einstein started off with very reasonable ideas based on the science of the day. He did not fumble in the dark, he was just an independent thinker who refused to bow to the conventional wisdom of physicists at the time.

  8. Re:Consciousness - right track / wrong track on Towards Artificial Consciousness · · Score: 1

    Everybody knows that quantum mechanics is the basis of all chemistry.
    I said "play a role." You can explain neuronal behavior with classic chemistry since they are macroscopic systems working at room temperature. Any quantum effects are spread out by decoherence over the size of the neuron (or its organelles) and destroyed by thermal noise so quickly that they are completely irrelevant on the timescales a neuron is working at.

  9. Where's the evidence? on Cells May Communicate Through Light · · Score: 1

    Creating light (thus swamping the communication) and detecting single photons are trivial. Since they didn't do these experiments I'll have to call BS and "correlation is not causation."

    Instead I'll claim that the protozoa communicate telepathically through hyperspace, and the hyperphysical properties of the different vessels they used influenced the effectiveness of the communication.

    That article confirmed my suspicion that a philosopher's main job is making mountains out of molehills in the absence of knowledge - again (like the post I responded to.)

    Visual sensation is what's going on in the brain. We don't know enough to speculate about it reasonably. End of story.
    And if you want to make unreasonable speculations go ahead but leave me alone - I prefer science.

  11. Re:Consciousness - right track / wrong track on Towards Artificial Consciousness · · Score: 1

    Firstly, the human eye can not see a single photon, it needs on the order of 10 to register light. If we could see single photons we would see quantum noise, which we don't. Some animals are hypothesized to see single photons though.
    However, you can use simpler non-quantum theories to explain how the rods and cones work. That means that the quantum effects that they are of course based upon are irrelevant. In particular, any superpositions are destroyed in extremely short time frames at the size and temperature we're dealing with here.

  12. Re:Consciousness - right track / wrong track on Towards Artificial Consciousness · · Score: 5, Interesting

    You sound like a philosopher. But these question have simple answers.

    "Now" is determined by the temporal resolution of the specific process. For thought processes, that's on the order of a quarter or half second. For auditory signals, it's less than 100 ms, for visual signals, it's even less, under 50 ms.

    "Red" is what your parents told you it is. A name arbitrarily assigned to a specific visual sensation, which is defined by the physical makeup of your eye.

    And finally there is no, zero, zilch scientific evidence that quantum processes play a role in neurons. That doesn't keep people from speculating about it because they think there must be something special, metaphysical about our wetware. No that's not required if you look at how complex the brain is.

  19. Re:Run, neanderthal, run! on Were Neanderthals Devoured By Humans? · · Score: 4, Interesting

    Humans actually have the best endurance of all land animals (better than horses - humans win long distance races against horses all the time.) I read that it's easy to catch a gazelle - just stalk it for about a day and it will lay down, exhausted and all you need is a stick or a rock to kill it. Some larger animals like moose take 2 to 3 days. There are still tribes that hunt this way and there's a theory that this was the primary hunting method of early hominids after they ventured out into the savanna - since their brain (hence energy needs) grew much earlier than there's evidence of weapons like spears.
