    Oh, and on the seal problems and such, it sounds like you know more than I do. However, I can tell you that there was a firm trying to move the Wankels back into airplanes because they can be amazing performers -- they're essentially a cylinder horizontally, so you can stack and arbitrary number of cylinders along a crankshaft. More cylinders = more power. You can get some insanely powerful engines, and with no real extra engineering: once you get to 2 cylinders, you get to 5 for free.

    And the power to weight ratio is fantastic. Nutty compared to a piston engine. Plus theoretically less failure prone, so it's ideal for aircraft. That said, I did have one engine just die on me. No fuss, no sputter, just quiet. Had to get a new engine, but turned out the dealer who said so was completely incompetent. I suspect I could have saved myself a few grand by going to some corner garage.

    So, yeah, lots wrong there, including failures, cost and the dealer system. A modern version could have tremendous advantages, though.

    Because it really was incredibly sweet.

    No, don't get me wrong, it wasn't that powerful. It was LIGHT. Nimble. Smooth. No piston vibration.

    It was low to the ground and very well designed. I Urge you to find one used and indulge yourself. But it was NOT powerful. It went 70 and made you feel like you were going 90. In normal driving, it accelerated fine, but not spectacularly. However you could absolutely FLOOR it and not worry about ripping the engine to bits because there was NO vibration. No opposed cylinders. Just faster rotation.

    It was so sweet.

    "Wankel"! "Wankel"! "Wankel"!!!!!

    I loved my RX7. I only got rid of it when I got married and we needed a "sensible" car. I still miss that car.

    I only did a 180 in it once, but it was the second day I owned it. The Wankel has a huge amount of power for the weight of the engine. That means the wheels disconnect from the road when you turn under power.

    I ran out and bought really expensive tires and 25 pounds of nails to put in the back trunk. Solved that problem.

    'Okay, I might agree to a point, but based on what you said, who is a real "scientist" in society?'

    and

    'Hell, point to a group of people that are generally better "scientists" than Doctors. '

    Look in academia, outside of medical schools. Doctors may be better scientists than John Q. Public is, but they're way worse scientists than scientists. And being better at science in a society which is just terrible at it wouldn't get you much. You need to be actually good at it.

    'I guess my point is that while you may be technically correct, its a moot point when viewed in context.'

    No. It's absolutely not. This is why bad medical research jerks us from "don't eat fat," and "that's odd. Fat free potato chips still make you fat." or "Take these antidepressants. They're miracle drugs" and "Oh, wait. Seems they don't work more than placebo in most situations." Both initial studies made companies rich. We NEED science in the medical arena. And yet there are financial and social reasons why it's both not well taught and actively discarded.

    Drug company researchers have no reason to do good science. They have their corporate masters to please. Doctors have no vested interest in good science when bad science will get published in peer review journals and good science is usually less flashy and book-worthy than bad.

    "Reality limits people, and end of the day, doctors have lives in their hands. Its easy to criticize when you aren't actually doing the work."

    Doctors do not exist because they justify themselves, they exist because they serve the needs of others. Their blind spot with respect to science is tremendously damaging to the people they are supposed to be serving. It is easy to criticize. Very easy. But that's immaterial. It is easy to criticize when someone makes boat after boat which falls apart in the water. After all, can I make a boat? No, I can only criticize. And yet I'm sure you agree that as a society, we'd stop that guy from making boats. When doctors feel that they are in combat and do shoddy studies which perpetuate bad practices in the interest of time (call it expediency), society suffers until someone does a good study -- and that's a lot more suffering than than if doctors did good studies in the first place.

    And of course, most doctors don't do any science, and we shouldn't expect them to. What they do is read "science" and assume it's right, since they cannot tell bad studies from good. (Thank heavens for peer review journals, huh?) They then apply the ideas from junk science on us.

    I know you feel personal insulted by what I've said -- it's your chosen path. I honestly don't mean to discourage you or insult you. But look around in the next 6 years. Talk to academics outside of the medical field about the studies you're doing, if you do any studies. See if they don't have some very annoying suggestions on how to tighten up the rigor of your experiments. Change the pattern.

    "I just don't get what you are implying here. Do you think that Computer "scientists" are better scientists on average than doctors? because the answer is no."

    No, computer scientist are not scientists at all.

    Neither are doctors. Science classes generally don't prepare you for doing science. Chemistry, for example, most often does "experiments" in the lab which are actually demonstrations of observed phenomena. Stats classes do a far better job of preparing you to actually do science, but nothing prepares you better than actually doing it. Constructing experiments with human subjects is notoriously difficult. Doctors do (as we see with their publications) a terrible job. And they train their own. That's a bad system perpetuating itself.

    "Science" classes don't generally prepare you to do science for exactly the reason you point to with your computer science comment. We call a lot of things science in modern society, but we don't understand what real modern science is -- the concept of the pursuit of truth without ever absolutely being able to prove what is. We just come closer and closer to the truth while disproving hypotheses. Society doesn't like that definition very much. Drug companies don't like it very much. (It's unsatisfying at a human level, certainly.)

    "Your points about prestige might be valid, but i would counter with a very hard leek at yourself. We know VERY little about the human body, most of what we know is from observation, not deduction."

    After looking very hard at myself, I deduce lots of things. But that's Francis Bacon's idea of science you're describing (circa 1600), not a modern one. It's also the common conception of science, and that's a problem. (It's also probably your hypothetical surgeon's idea of science, even though he's been told different, since A. most of what he reads and sees and uses is science ala bacon, and B. a surgeon is generally the same as a dermatologist, though he may have been a better student, had steadier hands, worked harder and did very different post-school work -- he still has the same foundations.) Deduction is only the first step and sometimes not even really a required one -- it's the further steps of experimentation with well designed experiments which eliminate theories and provide real knowledge.

    Finding cures, by the way, isn't science, most of the time, anyhow. Eliminating cures generally is science. Medicine, as you make clear in your post, is about trying stuff, seeing what works, and running with it. It's also about the application of tech and experience. Doctors do all that. They do a fairly good job. The medical profession educates its own to do that. But it does a bad job of science. It's not the same thing.

    I suspect you think that I think that doctors are stupid. I don't. I think they're very well educated in their trade. That's called vocational school -- modern universities have been slowly stuffed full of vocational school ideas in the 20th century. And no, I don't think they're our best and brightest -- they start off as our best students, certainly, but we fail them by allowing and even encouraging them, at least financially, to get an education which only prepares them for being a doctor in our current conception of what a doctor is. That's a self-perpetuating cycle that gives us what we have. And part of that is bad science.

    It's much harder to get funding to do medical research without an MD than it is to do it with one. So in order to get funding, people who have real science backgrounds and understand science spend 6 years getting an MD before they can get funding to do what they wanted to do 6 years before, and during that time, they are surrounded by bad methodology which they need to resist picking up. Then the papers that they write go to peer review journals -- and if they're in medical journals, they're reviewed by people who love their Bacon. Guess which articles they're more likely to like?

    Bad cycle. Bad science. I suspect you could do a lot

  11. I see your problem right there: "Science" on Meta-Research Debunks Medical Study Findings · · Score: 4, Interesting

    Doctors are notoriously bad at doing scientific investigations, and since peer review journals are reviewed by peers, they don't know bad science when they see it.

    I've been arguing with my father about this for... what, fifteen years?!? He subscribes to the New England Journal of Medicine and is forever telling me about the latest study telling you to that standing on one leg reduces breast cancer in nuns. These studies are, without fail, trivial to eviscerate as their control groups are either non-existent or very poorly picked.

    Doctors just don't know much about science. That shouldn't be surprising. They have terrible educations. After all, they studied premed in college and then went to a vocational school. MD/PhDs really ought to do better, but I suspect they do their doctoral work with faculty who come from the same under-educated group.

    The problem is one of prestige. You cannot walk into a group of doctors and tell them why they're dumbasses and what to change. They know, and society confirms for them, that they are the best educated people on the planet and smarter than anyone else. "Heck, just look at our paychecks," they might respond. "That proves it right there, doesn't it? Figure it out from that data point only -- you don't need a control group."

    "Were people contemplating this back in 2004? The idea of video cards being used for general purpose computing is not very old. Transcoding user-generated video from one format to another was not very common until YouTube got popular."

    Encoding isn't transcoding, though they're similar. People have been encoding for a long time and always looking to offload any of the task onto some other processor. You live in a time when some encoding can be done in real time with a general purpose CPU. In the 90's, when I was doing encoding, any way one could scratch a little more speed by getting something else to do the work made a lot of sense.

    I suspect that there is prior art on the concept (though perhaps using different algorithms) which date back to the first GPUs. Things were really slow, and people were desperate. If I remember correctly, I wound up buying a card for a PC with two PowerPC chips in on it. That was not cheap. And yes, I know, not prior art. But I strongly suspect that some people in my position probably tried to do the same things with their Voodoo cards, which would be.
