  1. Re:Cheap energy is social justice on A Step Closer To Cheap Nuclear Fusion · · Score: 1

    That's essentially what Thomas Malthus thought. It was incomprehensible to him that people would willingly restrain themselves in the face of greater resources.

  2. Re:Theory? No. Hypothesis. on A Step Closer To Cheap Nuclear Fusion · · Score: 1

    You keep using that word. I don't know it means what you think it means. Theories don't "hold". Theories are verified and verifiable explanations of the behaviour of natural processes.

    Newton's theories were shown to be accurate under the conditions which he had experience but fell apart under unusual conditions of strong gravity and high velocities. They were replaced by Einstein's theories of relativity under the conditions where Newton's were no longer adequate. Both described behavior of natural processes accurately under many conditions but Newton's theories inevitably needed to be extended by Einstein's to better explain those natural processes.

  3. Re:Keep at it, guys! on A Step Closer To Cheap Nuclear Fusion · · Score: 1

    I can't help but remember all the talk about nuclear fission doing the same thing- energy too cheap to meter and all. Fusion as it is currently is dependant on Deuterium and Tritium fuel for the most part and Tritium is mostly produced from the Li6+n => He4+T and Li7+n => He4+T+2n reactions both of which must occur in a high neutron flux environment (conventional fission reactor) which makes the first fusion plants very dependant on fission reactors for fuel production. What is worse is that you'd have to produce about a dozen Tritium nuclei for every Uranium atom fissioned just to make fusion produce as much energy as the fission reaction that was used to synthesize the fusion fuel in the first place. The future of fusion that *may* approach what you're expecting of it will likely involve aneutronic fusion reactions such as the B11+H1 => 3He4 reaction among several others. THe problem is that they are much more difficult to get working than D+T fusion. The B11+H1 reaction requires a roughly 10^9 degree core to work which is nearly ten times what D/T does.

    The public needs to be shown that the word "nuclear" is not cause for panic. Better yet, not to judge technology such as NMR as being dangerous simply because of the name. But I guess it is too much to ask that they have even a basic competency in science.

  6. ah... on A Step Closer To Cheap Nuclear Fusion · · Score: 2, Interesting

    The idea is interesting- creating a self confining toroid of plasma instead of relying solely on external magnetic containment but from what I've seen of the "tech" it looks to be unfortunately the work of crackpots. Don't get me wrong, I really hope that they actually succeed in doing what they're claiming they can but I sincerely doubt it.

    It's the fusion of two isotopes.. which later break apart most of the time. A very small part of the time the ecited nucleus does not break apart: B11+H1 => C12 would you call that fusion and B11+H1 => 3He4 fission?

    I would agree with you however, the last eight years did a heck of a job destroying a lot of the freedom the US has been known for in the past. The scary thing is that Bush's policies are not likely to be reversed nor be an isolated incident. It's to the point where I've seriously considered leaving the US. The only thing really to consider is where to go...

    It seems to me that the US is on the road to getting left behind by other major powers in the world and that it could very well be that a lot of the educated people leaving see this as well. China in particular is effectively producing as much if not more than the US is and is growing rapidly. Europe is just about the same way.

    Funny how many people forget just how much the government has to do with the hostile treatment that immigrants face upon entering the US. Considering how much red tape and utter nonsense is baked into the system it isn't any surprise that a lot of educated people want the hell out of here.

  16. Re:article is BS on On the Efficacy of Flu Vaccine · · Score: 1

    ok then what is the "best effort" treatment in this case? The flu is a virus, there is little to nothing you can do once it is there. Anti-virals are somewhat effective but that is once you've already got the illness. The fact is that the vaccine its self is the "best effort" here... *if* it works. If it doesn't work or even worse, actually increased the risk of death then it would be unethical to have given the treatment without first doing an informed consent study on the vaccine just like any other drug that is on the market. Don't you understand? It's unethical to just hand out treatments without actually testing them first!

  17. Re:article is BS on On the Efficacy of Flu Vaccine · · Score: 1

    There is a big difference between what happened in Tuskegee and modern clinical double blind studies. FOr one thing, the people in the case of Tuskegee did not give informed consent to be part of a study. *That* is unethical. Running a double bind experiment where all parties are properly informed of the nature of the study and with proper procedures in place is not unethical.

    FTA:

    One important clue: The ribbon runs perpendicular to the direction of the galactic magnetic field just outside the heliosphere,

    It looks like the ribbon is a side effect of the interaction between the galactic magnetic field and the heliosphere. It's possible that the interaction between the two causes particles to either collect in that region or direct those particles from that region toward Earth.

  21. Re:article is BS on On the Efficacy of Flu Vaccine · · Score: 1

    It just seems to me that the only reason for the article to have mentioned it would be to imply how "worthless" these vaccines supposedly are. As if 36,000 people aren't worth the trouble just because the flu virus isn't the top killer. I mean, you could use the exact same argument for car accidents and it wouldn't detract from the need for car accident safety testing any more than the article's assertion does for flu vaccination and testing.

    Influenza causes only a small minority of all deaths in the U.S., even among senior citizens,

    36,000 die of complications from the flu annually in the US. That's very nearly as many as die from car accidents.

    There is a very simple way to test the effectiveness of a vaccine and that is to carry out a double blind study utilising placebos alongside the active vaccine. Any effect that is solely due to the "healthy user effect" would be virtually eliminated.
    further problems: the article has no references, no real hard data from relevant studies and several studies contradict the article's assertions.

    My grandmother has severe memory problems. We have tried a system very similar to what you describe and frankly, once her memory got bad enough to need such a system, she couldn't remember to note the things she should remember. We did most of the note taking for her and she would forget to use them. Honestly, the camera may help with memory problems just due to the fact that it does it automatically but really it may just come down to her forgetting why she has it and leave it somewhere. What people with memory problems like hers really need is care and attention from their family and friends. It is as simple as that. They're going through life with pieces missing and they often know it and that is really hard for them emotionally and no camera is going to fix that.
