    I wonder why they would do that, given the known lack of correlation between the harshness of penalties and the occurrence of crimes.

    Texas, for example, has one of the highest murder rates in the US, and also has extremely harsh penalties, including the frequent use of killing convicted murderers.

    North Dakota, in contrast, has one of the lowest murder rates in the US, and has never employed the practice of killing convicted murderers.

    Ah, the old cherry-picking anecdotes and calling it "data", never missing in political discussions...

    Claiming "lack of correlation" is somewhat like claiming the inexistence of something, you have to present complete data to prove it. Otherwise it's like claiming the Amazon river does not exist because it's not in Texas or North Dakota.

  3. Re:WTF? on Senate Panel Backs Patent Overhaul Bill · · Score: 1

    Doesn't this screw over people who invent something and don't want it patented, or can't afford to?

    No. Those people wouldn't have a patent anyway, so why should they complain?

    If you are an inventor who cannot afford to patent your inventions you need an investor to finance you. You would need a partner anyway if you are poor and wish to produce your invention.

    If you want to give your invention as a gift to the world you should patent it and licence the patent for free. Yes, it sucks, paying for the patent process if you just want to release it for free, but that's the way it is when you have patents, no matter if the priority goes to the first to invent of to the first to file.

    That library should have an awesome security around it. It's one thing to keep data secure, that's difficult enough, keeping a collection of biological weapons secure is an entirely different thing.

  5. Re:Radiators on US Team Seeks To Top Steam-Car Speed Record · · Score: 4, Informative

    There were a few condensing steam locomotives built. I don't know why they weren't more common, surely a train has space enough to fit a condenser there and stopping to get water must have been a PITA.

    In the 1960s Bill Lear a very prolific inventor started working on steam cars. By then Lear had already a number of important inventions to his name, among them the car radio (he created the name "Motorola") and the business jet plane (Lear Jet).

    He claimed to have the condenser problem solved by 1969, using an advanced accordion-shaped radiator, but nothing came of his steam car plans. I remember seeing an article on Popular Science mentioning he had a steam turbine bus prototype.

    He also had plans for a steam powered race car to run the Indy 500. This car would use a delta-shaped engine, inspired by the Napier Deltic

  6. *ALL* kind of alternative fuels? on US Team Seeks To Top Steam-Car Speed Record · · Score: 3, Informative

    And the main advantage "can burn all kind of alternative fuels"? Come on, I can do that with my diesel engine already

    I'd like to see what sawdust, wood chips, grass clippings or charcoal would do to your diesel engine. Even liquid fuels will not work if they are high-octane, like ethanol. Diesel engines require liquid fuel at a certain cetane number range.

    A steam engine, OTOH, has basically a single requirement for fuel: it must burn without damaging the boiler.

    According to TFA,

    "So far as prayer related to astrology is concerned, the Supreme Court has already considered the issue and ruled that astrology is science. The court had in 2004 also directed the universities to consider if astrology science can be added to the syllabus. The decision of the apex court is binding on this court," observed the judges.

    Apparently India's Supreme Court has already made a ruling about this and the lower court is just following orders.

    What a shame, those engines really belong in a museum. They are Mig-15 engines which have centrifugal compressors and are similar to the first British jet engines developed in the early 1940s. Actually, from the outside, these look a lot like the De Havilland Ghost.

    The Mig-15 used ttechnology the Soviet Union got from the British during WWII. During the Korean war these centrifugal compressor engines were already obsolete and the Mig-15 was inferior to the American F-86, powered by the axial flow J35 engine.

    Let me see, they put a routine in the customer's computer that collects what the customer types and what is sent to the screen when the customer uses a third party application.

    Let's parse it:

    "When Wolfire Games released their animal martial arts games" - this gives the epoch when the rest of the sentence happened, it was all at the same time as the game was released

    "'Lugaru HD', on the Mac App store," - this is a more detailed explanation that tells us what game was that and where it was released

    "shortly after they could be forgiven for thinking they were seeing double" - this is a more detailed explanation of the time, it all happened shortly after the time when they could be forgiven

    At the very least this could have been couched with a "might" or a "maybe"

    Blame the journalist who wrote the article, not the scientist. Scientific papers always give the exact range of confidence one can have on its conclusions and usually the raw data is available so you can draw your own conclusions.

    No matter how accurately we can observe an exoplanet from Earth, at this distance, most of that interpreted data is not much better than a guess.

    More accurate observations are no better than inaccurate observations, is that what you mean? Do you think that if the distance is big enough then there's absolutely no way you can improve the accuracy of your observations? That notion has been disproved long ago.

    But I remember watching a number of science documentaries that credit the moon for the persistence of life on Earth

    And the moon, with the solid tides it causes on the earth lithosphere, may be the reason why there are plate tectonics on earth.

    Besides, the tides on the oceans may be one reason why life arose on earth. When the moon was closer, tides were much higher, hundreds of meters. That caused increased erosion that may have been the origin of the clays that many theories consider essential scaffold for the first self-reproducing complex molecules.

    I imagined at least 10x10cm mirrors. Now that would have been "solar power".

    True, if there had been 5800 10x10cm mirrors. For the same surface size, the smallest the mirrors are the better focus he will get. Ideally, the surface should have an infinite number of infinitely small mirrors, i.e. it would be a smooth parabolic surface.
