  2. Imperial System != US Customary on NASA Sticking To Imperial Units For Shuttle Replacement · · Score: 3, Informative

    The Imperial System of measurements is not the same as the customary measurements used in the United States. The legal arbiter of measurements in the United States is the National Institute of Standards and Technology. Apendixes B [PDF] and C [PDF] to their Handbook 44 provide a good overview of the structure of the respective standards and their relationship to SI (the science based International System, which was based on the Metric System).

    The word system seems misleading when applied to US customary measures. For example:

    Appendix B. Section 2.2.5. From 1893 until 1959, the yard was defined as equal exactly to 3600/3937 meter. In 1959, a small change was made in the definition of the yard to resolve discrepancies both in this country and abroad. Since 1959, we define the yard as equal exactly to 0.9144 meter; the new yard is shorter than the old yard by exactly two parts in a million. At the same time, it was decided that any data expressed in feet derived from geodetic surveys within the United States would continue to bear the relationship as defined in 1893 (one foot equals 1200/3937 meter). We call this foot the U. S. Survey Foot, while the foot defined in 1959 is called the International Foot. Measurements expressed in U. S. statute miles, survey feet, rods, chains, links, or the squares thereof, and acres should be converted to the corresponding metric values by using pre-1959 conversion factors if more than five significant figure accuracy is required.

    Does this make a difference? From one viewpoint, no, when do you ever need to keep something accurate within 2 mm over a mile? From another, yes, repeated iterations of computations based on incorrect conversions can produce just plain gibberish. Another bit of measurement chaos to keep in mind:

    Appendix B. Section 2.3. British and United States Systems of Measurement. ... In the customary British system, the units of dry measure are the same as those of liquid measure. In the United States these two are not the same; the gallon and its subdivisions are used in the measurement of liquids and the bushel, with its subdivisions, is used in the measurement of certain dry commodities. The U. S. gallon is divided into four liquid quarts and the U. S. bushel into 32 dry quarts. All the units of capacity or volume mentioned thus far are larger in the customary British system than in the U. S. system. But the British fluid ounce is smaller than the U. S. fluid ounce, because the British quart is divided into 40 fluid ounces whereas the U. S. quart is divided into 32 fluid ounces. ...
    1 U. S. fluid ounce = 1.041 British fluid ounces
    1 British fluid ounce = 0.961 U. S. fluid ounce
    1 U. S. gallon = 0.833 British Imperial gallon
    1 British Imperial gallon = 1.201 U. S. gallons

    We also must remember that NASA has proven itself incapable of managing the different systems of measurement before. Ten years ago NASA crashed a Mars bound probe because of botched conversions from customary to SI units. You would think that having paid $125 million for that lesson, they would want to avoid a recurrence. But, I suppose that they are from the government and they do not have to care.

  5. Re:This might be controversial, but... on Princeton Boasts Its Kindle Project Is Noblest · · Score: 1

    Paper books, if properly cared for, can last hundreds of years. I have some books that my parents purchased before I was born which are still in good condition today, and I'd like to be able to pass them on to any future children I might have.

    True story: Many long years ago, in a previous millennium, when I was a college freshman, the Lord of the Rings Trilogy was published in mass market paperback format in the US. (It was originally published in hardback in the US around 1954). I read it at the urging of a professor of medieval history, and I loved it. I kept the books through many moves and changes in my life.

    About 30 years later, my youngest child entered middle school and developed a taste for reading fantasy. When he wanted to start reading the Lord of the Rings, I gave him my books. The pages of the books, being of newsprint quality like any mass market paperback, crumbled as he read them. He reproached me with the poor quality of the books. I apologized, if only I had known HE would want to read these books, which cost me $0.95 each 30 years ago.

    I bought him new books of his own, on better quality paper, so that he will be able to give them to his son, I hope.

    There ain't no such thing as a free lunch.

    Mr. Stallman, and the ever shrinking group of people who care what he thinks, need to grow up. Nothing is free. Absolutely nothing. Everything has a cost. And everybody is subject to constraints on their knowledge, wisdom, and actions.

    If we are lucky, the costs are well within our ability to pay, and the constraints are not heavier than those that rational civilized men place on themselves for the sake of good order and pleasant society.

    This is bog standard litigation tactics. It is done in many cases. One side, sensing a tactical advantage, demands a deposition (out of court, but sworn and recorded testimony) from a person on the other side who thinks he has better things to do. The other side file papers accusing the the party of the first part of having sisters and being lawyers. This will go on and on, until the case ends when one or both parties decide they no longer want to waste time and money like this.
