  1. Re:Sick of this... on Royal Society of Chemistry Slams UK Exam Standards · · Score: 1

    Photoeffect and basics of QM (solution of the Schroedinger equation for one-dimensional potential well) were in textbooks back in 60-s. Anyway, most of school physics is still classic mechanics and thermodynamics.

    Representation might have got finer, but not by much.

    School-level chemistry has not changed much, I've checked it. It is just too basic (pun not intended)...

    Math - yes, I was wrong. Mea culpa.

    Yes, I agree.

    Math is vast and there are lot of ways to teach it since a lot of areas scarcely overlap.

    I realized it after I've posted my answer.

    Complete bullshit.

    Computer science is about the only _really_ new science studied at school. The rest of science taught in school changed very little since 50-s.

    Let's see:
    1) Physics: school-level classical physics has not changed much in 150 years. School-level thermodynamics has not changed for 100 years. Ditto for electrodynamics (Ohm's law, simple RC circuits).

    2) Chemistry: essentially no changes since 60-s. Nearly all modern advances in chemistry are related to organic chemistry and/or complex chemical reactions which are not studied at school.

    3) Math: no changes at all. School-level math is about 150 years old.

    4) Biology: a lot of revolutionary changes. Unfortunately, they are usually mentioned only in passing in school curricula.

    Sure. But you also need good-quality 3D drivers. This way Microsoft will be able to run Aero even on plain VESA framebuffer.

    Also, consider this: the upcoming Intel Larrabee graphics card will consist of 64 independent programmable x86-compatible cores. NVIDIA CUDA also allows direct GPU programming.

    I bet this renderer will be adapted to run directly on such GPUs bypassing their 'native' rendering pipelines. That'll give Microsoft freedom to experiment with new feature such as ray tracing without any help from hardware vendors.

    DirectX 10 on CPU is _NOT_ intended for games.

    It'll be used for rendering the Aero interface. And it requires several orders of magnitude less computing power. Hell, even my old 4-year old ATI Radeon 9600 can render Aero just fine.

    Games make a useful test-case, though.

    Why not?

    It certainly shows that their software renderer is fast and feature-complete enough to run fairly recent games.

    I don't like hunting, so I was not very interested. I've heard that sometimes soldiers from this base hunted bears with AKs, but from helicopters :)

    PKM surely will do some damage, though I wouldn't want to fire it in a small room :) Probably, a sniper rifle like SVD with armor-penetrating bullets should work too.

    Yes, it will.

    But the main question is what bear will do after it? It will probably attack you if a slug does not penetrate its brain or if bear does not go into a shock immediately.

    But bears are incredibly tough creatures. There are stories of bears who ran several kilometers with bullets lodged in their hearts.

    AK-47 doesn't help much against bears too.

    I (briefly) served on military base in Siberia, and almost the first thing we were told is that you shouldn't use AK to shoot bears. With a lot of chilling stories of people who tried it.

    PS: bears were a problem there. They usually do not come close to people. But if a hibernating bear wakes too early or can't start hibernating, it can become mad from hunger (there's not much food during the winter) and start attacking people.
