    Britain was involved in the settlement and creation of modern-day Israel. Israelis and Palestinians often kill each other. It's not a real connection but I think this is what he's going for.

    How do you define "often"? The total death toll of the israeli-palestinian conflict since the beginning of the first intefada in 1987 is about 8000 people. That's less than 365 per year (8000/22). (This figure includes both civilian and military casualties on both sides). There are about 10 million people living in Israel and the West Bank and Gaza. So the death toll from the conflict is 3.65 deaths per 100000 people per year. In the United States, the death toll from car accidents is 14.7 death per 100000 people per year. Maybe that's "often" but I just wanted to put it in perspective.

    If you wanted to pick a conflict that the British were involved with a high death toll, the israeli-palestinian conflict is a pretty poor choice.

    You are correct that we can't extract a significant amount of the wind energy. But wind flow is pretty tricky, and even if farms wouldn't affect flow in the upper atmosphere, they could affect flow where we care about it. at the earth's surface.

    I would say that this is still an open question.

  6. Re:Problem with wind and solar? on Expanding the Electricity Grid May Be a Mistake · · Score: 1

    I have the same concerns about wind energy. There is some evidence that it can effect local ecology.

    Solar energy on the other hand, isn't used very efficiently. In fact, in much of the world shade structures that converted solar energy to electricity would provide a double service: cool via shading while using unwanted radiative energy.

    The only way that using solar could effect climate is if we significantly changed the albedo by placing dark solar panels in a place that was very reflective. However, other than the polar ice caps most of the earth's surface absorbs the solar energy, so we really would not affect climate by "taking out" the solar energy.

    I think we should actually launch solar concentrators into orbit. Basically huge inflatable lenses that float in space and beam concentrated solar power down to heat some salt to drive a turbine. We'd just have to make sure that planes didn't fly through the beam.

    Yes, our species is more than DNA. That is obvious. What is not obvious is that we should confuse the process of Darwinian evolution with cultural evolution. They are both fascinating and worthy of discussion and study. It is even worth thinking about ways in which they are similar. But I think it is also worthwhile to understand the distinctions and that models of one need not apply to the other.

    Back in my day (I'm 48)....

    When I was a young whipper snapper in the 70's-80's. I'd buy an album and copy it to tape for my car. If asked by a friend for a copy, I'd take a blank cassette tape and make a copy in my cassette recorder with the high speed dub feature.

    I don't ever recall the cops ever asking me if I got pulled over for speeding or something..."BTW son, Do you have a license for all those home recorded cassette tapes back there."

    Really? You can't tell the difference between sharing amongst a group of friends (or even friends of friends) and one person buying it , posting it online for thousand or hundreds of thousands of people to access?

    I'm don't think that the RIAA is handling things in the right way. They are a bunch of scumbags. The answer to this is to make media cheap and easy enough to access legally, that most people wouldn't bother stealing. But, the internet has fundamentally changed access to media in a way that makes the "making tape copies" precedent irrelevant.

    I think the personal information example makes a clear point. In the old days anyone could have, with great effort, gotten hold of a white pages for any city and tried to find someone's address and phone info. Or for a few hundred dollars hired a PI to get info.

    Now, you can get address, phone or even reverse phone info instantly and for $5 you can find out everything about a person without leaving home. I think that's a qualitative different, not just a quantitive difference. But legal theory has a hard time with that concept.

  9. Re:A few things are clear on First Images of Memories Being Made · · Score: 2, Insightful
    The "normal" definition of dualism is that there is a physical universe and a metaphysical universe. Science is a method to understand the physical universe, but cannot tell us much about the metaphysical one. If consciousness is metaphysical then neuroscientists, like me, are not going to be much good at figuring it out.

    I think many people confuse physical with deterministic. There are many physical systems that are non-deterministic and I would argue that the brain is one of them. We don't yet know the source of non-determinism in the brain. But there are generally two classes of non-mutually exclusive theories.

    1) There is intrinsic noise in the brain. The human brain is kept at a balmy 37ËsC which provides for plenty of Brownian noise. (I could expand on this at length.. but i have a flight to catch soon)

    2) There is a neural circuit that acts essentially as a roulette wheel in our brain. Why, you might ask, would you have a casino in your head? Because in a competitive world predictability = death. (See this). This was more or less, the insight that John Nash had when he came up with the Nash Equilibrium, a critical contribution to game theory .

    And a quick comment on the question of who are we but our memories? It turns out that we have different kinds of memories that are stored in different parts of our brains. Some of these memories would more normally be called beliefs or strategies but are formed in a very similar way as "normal" episodic memories (like what you had for breakfast). When someone starts to lose their memories of what they had for breakfast (or whether they live, etc) we call it amnesia, and we can often still see remnants of the person (they might have the same moral compass) and they still know how gravity works, etc. When the more basic belief and rule memories start to go, we often use a different word, "dementia", to imply that the person is not acting like themselves, but rather a demented version of themselves.

  15. Re:Chose a sense on Hacking Our Five Senses and Building New Ones · · Score: 3, Informative

    I thought we had 11 senses... Why do we keep teaching that we have 5!?!?!

    As is pretty clear from the wiki link in the parent post, stopping at 11 human senses is about as arbitrary as stopping at 5 human senses.

    So how many senses do we have?

    You can take a reductionist approach, and count the different type of "sensory receptors" in an organism. Let's define a sensory receptor as a protein on a peripheral neuron that responds to external events. However, this definition leads us to the conclusion that each kind of cone in the retina is a different sense. This implies that vision is 4 senses (3 cone types, and 1 rod type of photoreceptors) and not 1 sense. If we did the same for touch,smell, and the other ' traditional senses' we would arrive at a number over a thousands (Ok... smell is most of that , but even without smell there are many more than 11).

    We get into even more trouble if we allow our definition to include changes in the central nervous system (the brain and spinal cord) caused by external events. For example, inhaling, ingesting, or injecting stuffs leads to changes in varied receptors in the brain. Is this a sense? When you fall down and hit your head, that induced changes in the brain. Is that a sense? When you get an unexpected reward, your brain gives you some dopamine. By this definition you could say that you have a 'dopamine' sense.

    The other approach, which might be more intuitive (and is closer to the classic definition), is a systems level approach. We see, we hear, we smell, we touch, we taste. 5 senses. And we feel acceleration, we feel sharp pain, and dull pain, and burning pain, etc. But if these are all senses, why not include the other feelings? Feeling afraid, sad, happy, horny, sneaky, humiliated, disgusted. These feelings can also be caused by external events. In fact, in the mac dictionary, one definition of feeling is "experience a sensation".

    There are valid historical reasons why we separate things like vision from things like sadness. But as we learn more about brain and behavior those reasons are fading. So instead of asking how many senses we have, maybe we should be asking what's the rank of human experience?

Direct experimentation using air pollutants, especially particles, to investigate their effects on humans or on animal models of asthma provides corroboration of the epidemiology and has begun to identify the pathophysiological mechanisms involved...."

    yes, climatology is complicated. It is a non-linear dynamical system

    The warming of the planet (which is agreed upon - the only controversy is whether this is a natural cycle or man-made) is just putting more energy into this system. When you add energy to a dynamical system 2 things can happen.

    1) You can stay in the same regime, but increase the variance in the oscillations. In layman's term, we will have the same kind of weather but it will fluctuate more than we are used to, storms might be a bit more severe, we'll have hot days and then cold days, etc.

    2) The other possibility is that we shift to a new regime. In other words, we cross some energy barrier and move into a landscape that is totally new for humans. For example, a world without polar icecaps. A hot earth. If this happens... well, things will be interesting. probably not in a good way.

    I can say with some confidence that no one knows what will happen. But it is unequivocal that we are poisoning the earth. Pollution is destroying our food and water supply. It is giving our children asthma. It's wiping out some species and mutating others. This is something we can see happening now and yet, we still can't get people to change their behavior. what is it going to take to get people to realize that our current lifestyle is not sustainable?
