    His criticism of SERI is basically saying "the hypothesis that the neutrino has a rest mass of zero is scientific, but the hypothesis that a neutrino has a rest mass that is not zero is unscientific." This is silly; the same experiments would be used to test either hypothesis.

    No, Chriton is right. Assuming your experiments measure the mass of the neutrino with some error, then you can never falsify the hypothesis "neutrinos have nonzero rest mass." All the experiments can do is push the upper bound on the mass closer to zero*. Falsifiability is one of the requirements for a hypothesis to be scientific. Since your experiment can't establish the mass as zero, only require it to be closer to zero than the last experiment, no experiment you do can contradict the hypothesis. OTOH, an hypothesis that "the rest mass of the neutrino is at least X" is scientific for any X, as long as it is possible to conduct an experiment with that degree of accuracy (even if it's impractical). Similarly, the hypothesis that neutrinos have zero rest mass is scientific -- it would be easy to falsify, with any experiment that showed a nonzero mass.

    * (IANAPP, there may be experiments that distinguish between exactly zero and not quite zero that don't put an error bar around the measurement of mass. If that's the case, then either hypothesis is falsifiable.)

    No, that's an idiotic misreading of what Popper said about falsifiability.

    Saying "I'm doing an experiment to test whether the neutrino has mass" and saying "I'm doing an experiment to test whether the neutrino has no mass" is exactly the same thing. It is silly to think that this is scientific if it's phrased one way, and unscientific if the exact same thing is said with equivalent, but slightly different phrasing.

    His criticism of the Drake equation is even less well informed, in that he's criticising the equation itself, not the parameters that go into it. But the equation is trivially true; it's nearly a tautology. If the correct statement is "we don't know", it's not because the equations wrong, it's because we don't know what values go on the right side.

    From Crichton's piece: "The problem, of course, is that none of the terms can be known, and most cannot even be estimated. The only way to work the equation is to fill in with guesses." He IS talking about the parameters (on the right side). Your criticism is meaningless.

    Nope. Crichton said, direct quote, "the Drake equation is literally meaningless, and has nothing to do with science."

    Not the values of terms that compose it. The equation itself.

    Crichton's criticism is literaly meaningless, and has nothing to do with science. In short, Crichton should stick with novels, which he's good at, and not critiquing SETI, something he seems to know little about.

    Michael Crichton's criticism, unfortunately, is uninformed.

    His criticism of SERI is basically saying "the hypothesis that the neutrino has a rest mass of zero is scientific, but the hypothesis that a neutrino has a rest mass that is not zero is unscientific." This is silly; the same experiments would be used to test either hypothesis. Likewise, it's silly to criticise SETI by saying it's scientific to listen for radio signals if you're trying to show that there aren't any, but it's not scientific to listen for radio signals if you're trying to see if there are any. It's the same experiment either way.

    His criticism of the Drake equation is even less well informed, in that he's criticising the equation itself, not the parameters that go into it. But the equation is trivially true; it's nearly a tautology. If the correct statement is "we don't know", it's not because the equations wrong, it's because we don't know what values go on the right side. But the answer "we don't know how many civilizations are in the univererse because we don't know what the probability is that a planet with life develops a lifeform with intelligence still bounds the question-- it tells us more precisely what we don't know.

    In short, Crichton should stick with novels, which he's good at, and not critiquing SETI, something he seems to know little about.

    Amazing how the blindingly obvious can get headlines.

    If all the different criteria all gave the same result, then there would be no need to make a weighted average; you could just look at any single one. If they give different results, then of course the result will depend on how you weigh them. In fact, if a college ranks number one on any of the criteria, clearly a weighting exists to rank that college number one overall (just rate that one factor 100%...)

    from Wikipedia

    "In August 2004, Senator Ted Kennedy (D-MA) told a Senate Judiciary Committee discussing the No Fly List that he had appeared on the list and had been repeatedly delayed at airports. He said it had taken him three weeks of appeals directly to Homeland Security Secretary Tom Ridge to have him removed from the list. Kennedy said he was eventually told that the name "T Kennedy" was added to the list because it was once used as an alias of a suspected terrorist. There are an estimated 7,000 American men whose legal names correspond to "T Kennedy". (Senator Kennedy, whose first name is Edward and for whom "Ted" is only a nickname, would not be one of them.)"

    Addition is not a trade secret.

    However, given that we don't live in a world where the source code can be inspected without a court order, having an expert witness violate an explicit court order would, almost certainly, result in a world where the source code wouldn't be available for inspection even with a court order.
