  1. Re:Sad summary on US Wins Math Olympiad For First Time In 21 Years · · Score: 4, Interesting

    Its not just the US. Australia has a lot of data from national standardised testing, notably NAPLAN.

    Girls consistent score slightly higher on average in most subjects. I don't think this means any failure or conspiracy in our schools, as it is well know that boys develop later. The difference is very obvious in early school years. If it is considered "a problem that needs fixing", you could set the start age for girls a bit earlier, say six months, and the scores could be equalised. Or you could just accept the "diversity".

        However maths is a special case. Unlike all other areas, boys are a bit in front on average. More interestingly, the standard deviation is substantially larger, so there are more boys at both the bottom and top of scores. The higher the score band, the greater the disparity in numbers. (And again - only in maths) So it is no surprise if >90% of the olympiad-level students are male. If it was equal, something would be seriously wrong in the selection process.

    Data can be seen here: http://reports.acara.edu.au/Ho...
    Select domain:numeracy and subgroup:sex
    Note the M/F numbers in the first ("exempt") and last columns.

    Project that as a normal distribution, and it will predict that the Maths Olympiad is a sausage-fest. Mathematically.

    Well, thats happened. How is the revolution going?

    Last time you had a revolution, it killed 2% of the population (equivalent to 6 million today), and only benefitted the elite 1% . What was so terrible about Canada? For ordinary people, rules stayed the same, and taxes went up. Just a change of management. I'm not sure you can afford another one.

    Oh wow..so you're saying you can only have bolt action rifles down there?

    Yes, not even semi-auto .22s. But we keep them for hunting, not overthrowing the government, so it is tolerable.

    What about semi-auto pistols?

    Oddly, they are still legal, up to 10 rounds. And of course, criminals are much more likely to use handguns than assault rifles. But its a lot of hassle to get a handgun license here, and not many people have them. You certainly cannot carry them in public.

  7. Re:Aussie freedoms are inferior on Rich and American? Australia Wants You · · Score: 1

    Not the silly gun argument again. Hunting is popular in Australia, and we have more guns now than before the buyback. Just fewer assault rifles. People may regard the buyback (and ban on automatics) as a colossal waste of money, and an inconvenience. But having to reload between shots is hardly seen as a major attack on personal freedoms. No more than Americans resent the ban on private ownership of hand grenades. And it gives the kangaroos a sporting chance.

    ... Don't take it the wrong way... but I like the bill of rights. Put something in place that forbids the government from overstepping its bounds to any extent and Australia will be very interesting.

    Short of that... you're an interesting vacation destination. A nice place to visit but I need something like the Bill of Rights to call a country home.

    Well, you'd be quite at home in Russia then. Zimbabwe has a bill or rights too.

    What you really want is a thing called "rule of law". Australia has mostly the same rights as the US, unsurprising since both countries legal systems are based on British common law. We can all trace our rights back to the Magna Carta and beyond.

    I can get by without a bill of rights, but it was annoying having to quarter those soldiers in my house last year.

  9. Crime on Rich and American? Australia Wants You · · Score: 1

    It's got a lot more racial crimes, it's got a lot more gun-related crimes,

    On average, yes, but crime is a local thing. Areas of Sydney have drive-by shooting from middle-eastern crime gangs, and plenty of cities in the US are very safe.

    I don't know why rich Americans would want to leave - it is the poor people who are much better off in Australia. (unless they dream of buying a home)

  14. Re:WHAT radioactive materials? on Boeing Patents an Engine Run By Laser-Generated Fusion Explosions · · Score: 2

    but the key is, a lot of (read: "most of") the power is to come from fission.

    I really can't think that Boeing would be so daft as to think that anyone would ever use this on Earth.

    I think you may have missed that only the fusion products come out the back. The fission products are contained, and its relatively easy to contain the fission chamber in the event of a crash, unlike nuclear-powered spacecraft, which re-enter with 1000 x the energy of a subsonic aircraft.

    Surely the point of the patent is to use it for exploration of other planets. Right? I hope so...

    It has the advantage of operating without fuel or oxygen, but why would a planetary explorer need a jet engine? Whats the hurry?
    They can just float around with a small solar or RTG-powered propeller.

    Even if the technical challenges can be overcome, its hard to imagine this being economically viable over a conventional jet engine, even if you have to synthesise the fuel on the ground with nuclear power.
    I miss the days when to get a patent you needed a working model, instead of just a vague idea that might never work.
