    That is why the legend says soldiers with polished sheets of metal. From there on the quality of aiming at the focal point depends on how good is sarge with the baton and the "give me 80 pushups in full gear" aim correction method.

    Realistically a trained squad can aim and keep aimed around 40-80. Probably a 100 tops. That is more than enough to blind _ANYONE_ on the attacking ship in the days before sunglasses. I doubt that this would have been enough to set it on fire though. In any case, with the captain, skipper and most of the crew blind while facing catapults throwing burning tar buckets and 1m diameter stone balls the ship was as good as burning anyway.

The last pic going down is the 1944 equivalent of the orthodox deacon blessing the ICBM. Though in this case he ain't blessing anything.

    It does not matter how much you cook a spoiled chicken you will still be sick. You get sick from the toxins which are already in the meat at that point. Most bacterial toxins are not destroyed by normal cooking (and especially japanese style cooking which is quite "gentle"). Cooking is there to kill parasites - various flatworms, etc, not bacterial toxins.
    Similarly, you can eat as much as you like half-raw chicken. If the meat is fresh from a poultry which runs proper hygiene and a farm which runs a proper hygiene to western health standards you will not get sick. You will get constipated as hell, but not sick.

    Because they think positively as a matter of a 2000+ year tradition. Read Confucius and Kuhn before making such a comment for crying out loud.

    Positive thinking innovative engineering and revolutionary science does not make.

    You must think negatively and strongly dislike something which is in use today to produce something better for tomorrow. If you think positively about what you have today, you have no reason to make your brain look for something better. In fact as long as you continue thinking positively your brain will always at some instinctive level refuse to look into improving it. Further to this, in a positive thinking environments a paradigm shift - throwing out the old and bringing the new is guaranteed to be suppressed. You do not throw out the old and bring the new if you are thinking positively about it.

    When they start thinking negatively about themselves, what they create, what they do, what they invent, etc they will start to create innovative stuff. Until then the list in the GP post is pretty much spot on.

  14. Re:Molykote? on Molybdenite As an Alternative To Silicon · · Score: 5, Interesting

    Probably not pure enough.

    You need 99.995+% purity for most semiconductor stuff (99.999+ for CPUs and memory) which can be achieved only via zone smelting. In order to zone smelt the material needs to be able to re-crystalize after being heated locally in the first place. If it does not you can forget using it as a production semiconductor. There are in fact plenty of materials out there which have electron gaps are more "interesting" than silicon. We just have not figured out how to grow to purify them in quantity.

    As far as MoS2 is concerned it does not melt and does not recrystalize (it decomposes straight away) so zone smelting is not an option. It decomposes straight away. So frankly I do not see how you can achieve 99.99+ purity to do anything useful with it.

  15. Re:How will they compete? on Malaysia Releases Genetically Modified Mosquitoes · · Score: 4, Informative

    Dunno, in order to do that you need to release not 6000 but 6000000 the way they did it with screwworm flies in the south of the USA (and continue in Latin America).

    The screwworm control method is to release flies sterilised through radiation by the truckload so that most eggs are from at least one sterile parent so they do not hatch - hence no screwworm damage to lifestock. Year after a year after a year until there is no more screwworm fly (USA in 1982).

    So there is a scientific basis for this, just clearly not enough mosquitoes being released.

    Illegal in the US by the look of it.

    Bumpers do not comply to US reqs and doing US bumpers will spoil the aerodynamics and drop the economy way down. It is also most likely to remain safe _ONLY_ with seatbelts on. The windshield angle suspiciously resembles the one which forced Jaguar 10 years back to spoil the aerodynamics on some of the USA versions of their models so that idiots who insist on not wearing a seatbelt do not sue the company after a crash.

    Should be OK for most of the rest of the world which does not have the bumpers specified as a part of the safety standard and has seatbelts mandatory.

    I am not sure I would want to drive a 2 cylinder diesel though especially with kids succeptible to car sickness. The vibrations should be such that I would be cleaning their vomit from the upholstery after every trip.

  17. Re:Causation is not Correlia on Self-Control In Kids Predicts Future Success · · Score: 4, Insightful

    The data is right, the conclusion is wrong.

    The data clearly shows that US and UK schools fail miserably in educating the potential top 5% percentile of students (ditto for bottom 5%). The best students (especially male ones) are guaranteed to be in that "lack of self control" bucket. They are bored. Anyone who had a smart boy will tell you that based on experience (girls are slightly better at faking interest).

    I have seen it first hand with my 8 year old. He was assigned exactly in that bucket and had an "impossible to educate, needs psychiatric assessment" label in 2 schools. The lot - refuse to sit, lashing out, etc. Guess what, his granny taught him to read in another language with a different alphabet in 3 weeks at the age of 6. He has now managed to compensate for the 2 years when the teachers had him labelled as "impossible" and get back to his class level in English (4 years in 2) and to a level which is at least a year ahead of where he should be in math.

    I really hate to think where he could have been if his teachers did not assign him to the "non-compliant, belongs to the never succeed bucket" in his last year at the nursery.

  20. Re:Yep on How Chrysler's Battery-Less Hybrid Minivan Works · · Score: 1

    It is not a compressed air vehicle. In fact no compressed air enters any engine.

    You have only boost and only from hydraulic fluid with the gas compression tank being fully closed system. The boost you get from that is more than enough to do start and accelleration assist allowing both Start/Stop and a smaller engine.

    It is the same game as the original Prius or the Honda Insight/CRZ just with a small hydraulic motor instead of an electric one. Overall extra weight and volume to accommodate it looks the same as well. However it can last a lifetime instead of 3 years the way the battery lasts on the electric hybrid. Hydraulics is something which we know how to make to last. For example my dad's citroen GSA hydraulics were pretty much in top shape 15+ years after the day it rolled off the factory line.

  21. Re:It's pretty much the same here in the UK on America Losing Its Edge In Innovation · · Score: 1

    Actually, I beg to differ with both you and the article

    The reason why there are so many engineers in politics and management in places like China (and India for that matter) is that they pay them pittance so an engineering position is not seen as a lifetime vocation. China has a _VERY_ low glass ceiling for engineers. In China engineering is seen as a step-up to management as soon as possible because an engineering job cannot sustain you for life. So "Going Chinese" will not produce any innovation spurt whatsoever. In order to have a sustained innovation industry which is truly innovative and not based around producing cheap knockoffs of other people's work you have make engineering, science and R&D an acceptable life vocation.

    Coming back to the statement about UK - UK has long gone Chinese at least in the computer industry. The glass ceilings are firmly in place and _NO_ engineer in _NO_ profession can sustain a career progression from nerd to geek to ubergeek until retirement. He hits the glass ceiling at around 35 and has to become a manager where his career is similarly limited unless he spits on his engineering education and undergoes a full management conversion through an MBA.

    This is also where UK differs with USA. In USA you can remain a geek for life. It may not be easy, but it as at least possible. In the UK - definitely "no way". IR35 did away with the sole means of doing that. This is also one of the reasons why a lot of companies like IBM have now left UK for R&D. There is no point to bother with a country where nobody sees R&D as an acceptable long term career path. The fact that companies prefer places like Swiss with their astronomical cost of life is probably all that is needed to be said here. Plenty of examples - IBM, Google, etc.
