    Phone mast allergy 'in the mind'

    However, when tests were carried out in which neither the experimenter or participant knew if the mast was on or off, the number of symptoms reported was not related to whether a signal was being emitted or not.
    Two of the 44 sensitive individuals correctly judged if it was on or off in all six tests, as did five out of 114 control participants. So, perhaps a few double blind tests are in order.

    From the March 2008 Atlantic Monthly

    In reality, what the Olympic-era visitors will be discovering is not the absence of China's electronic control but its new refinement--and a special Potemkin-style unfettered access that will be set up just for them, and just for the length of their stay. According to engineers I have spoken with at two tech organizations in China, the government bodies in charge of censoring the Internet have told them to get ready to unblock access from a list of specific Internet Protocol (IP) addresses--certain Internet cafes, access jacks in hotel rooms and conference centers where foreigners are expected to work or stay during the Olympic Games. (I am not giving names or identifying details of any Chinese citizens with whom I have discussed this topic, because they risk financial or criminal punishment for criticizing the system or even disclosing how it works. Also, I have not gone to Chinese government agencies for their side of the story, because the very existence of Internet controls is almost never discussed in public here, apart from vague statements about the importance of keeping online information "wholesome.")

    Is U.S. income tax invalid because Ohio wasn't legally a state when the 16th amendment was ratified?

    The argument assumes that
    1. Taft was ineligible for the presidency, because he was not born in a State.
    2. Because he was ineligible, he signed the 16th amedndment illegally.
    3. Because it was illegally signed, the 16th amendment is without legal force and the income tax is unconstitutional.

    But Ohio, even if it was not a state, was part of the Northwest Territory. Since the relevant clause

    No person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President; neither shall any Person be eligible to that Office who shall not have attained to the Age of thirty-five Years, and been fourteen Years a Resident within the United States. refers only to the 'United States", and not to a "State", Taft was still eligible.

    Moreover, the President signs Acts of Congress, not Articles of Amendment. His signature was not needed for the amendment to be ratified. Since it was ratified by 42 of the 48 states (37 needed), Ohio's "disputed" status is immaterial.

    No. The problem has not been solved. Not at all. The lego model and the Mecano Model are not exact replicas.
    From the Mecano replica site

    A number of technical problems had to be overcome. First the representation of decimal digits - since standard Meccano is not well endowed with elements possessing a 10 fold symmetry, second finding a mechanism to reliably readout the value of a stored digit and add it to the adjacent column while retaining the original value, and finally organizing the overall drive mechanism such that the required torque could be distributed reliably with no slipping. The handling of carry propagation turned out to be one of the simpler aspects. Babbage was able to design specialized parts to fit his needs. In a sense, this makes the Lego and Mecano projects more admirable, but it's only with an accurate replica that historians can get a sense of

    1. How fast would it have been?
    2. How often would it have jammed?
    3. Could it have been used for its intended purpose-- publishing tables that were more accurate than the competitors?

    Those questions were answered with the first replica. The second model was bought essentially as a work of art for Mhyrvold's "living room."

    Sometimes, in this digital age, we forget that precision engineering is necessary. Models and designs don't necessarily scale.

    Consider a microscope, for instance. At the very lowest magnification, it's very basic-- a light source, possibly in the form of a mirror reflecting sunlight. A stage to hold the slide. A couple of lenses. A body to hold it all together. At higher magnifications, the light source needs to become more powerful and more reliable. The body of the microscope needs to be more rigid. Chromatic aberrations can obscure any additional detail, so you need special lenses. You might want a mechanical stage, so that you can zero in on the extra detail without jerking the slide about. You might want to put the microscope on an isolation platform if mechanical or building vibrations are disturbing the sample. A small improvement in signal to noise ratio may require extensive reengineering and considerably more expense.

    Babbage was trying to design a system that was more precise and more reliable than what was otherwise available. It was not enough for him to design a toy system and assume it would scale up without jamming, without loss of precision, without breaking. He had to produce a working machine. In the end, he never really finished. The faithful replicas help us understand whether Babbage would have succeeded if he had continued to receive funding.

    From Carol's site:

    Babbage's design could evaluate 7th order polynomials to 31 digits of accuracy. I set out to build a working Difference Engine using standard LEGO parts which could compute 2nd or 3rd order polynomials to 3 or 4 digits You can compute 3rd order polynomials by hand without too much strain. Seventh order polynomials are too difficult to reliably compute by hand--the mind numbing tedium might get to you after a bit.

    Nor can you build a seventh order difference machine out of legos.

    Plastic gearing and axles are subject to large amounts of flex and gear lash, which can be a significant problem where any level of precision is required. Babbage's machine weighs five tons because it was designed to be precise. The museum's machine weighs five tons because it is intended to be a replica of what Babbage created, not just an amusing simplification.

    Monty's choice of which door to open is constrained in two out of three choices. Pick the door he didn't open, and you'll win two out of three times.

    From an old article on Java education

    Marc Loy, a Java instructor and coauthor of O'Reilly's Java Swing, points to the ease of building graphical applications as one reason Java is well suited for an instructional language. "Beginning students can build real, live windows with buttons as they learn programming. This is a tremendous leap forward from the command-line interactions of old C, Pascal, and Fortran programs," said Loy.
    Since these interfaces look much like the applications students use everyday, they get a better grasp of the fact that they can write real programs if they stick with it. Loy added, "That ability to motivate the student to want to know more is also a key to Java's usefulness in the classroom." Introdutory classes are always a compromise between reaching out to the potentially unmotivated and sticking to the basics, though.
