Compared to mathematics, all else has fuzziness. This includes physics and chemistry. Fortunately for the physicists, Kepler was before the telescope, so he could formulate his laws; Cassini produced the "Ovals of Cassini" as an alternative because the differences had already been seen. It was fortunate in chemistry that they did not have accurate scales until recently, or they would have been faced with the isotope effect before being ready for it. >The engineers, on the other hand, will be able to pick up the >logical/deductive tools they need along the way through experience, >apprenticeship, and independent reading if for some reason they are >neglected in the formal curriculum. I doubt that this is the case. Engineers are prone to make assumptions unconsciously because that is all they know. During WWII, mathematicians and physicists were able to succeed where engineers could not, because they could think in terms of what the problem was, instead of which techniques to use to solve it. They may know how to solve differential equations, but not how to formulate good approximations to their problems which they do not know how to solve. -- This address is for information only.

Here in New Mexico, a gun isn't "loaded" unless it can by fired by just squeezing the trigger, i.e. there is a round in the chamber. This makes a semi-automatic pistol with a full clip but no round in the chamber legal to carry concealed in your pocket, but a utility or Swiss Army knife illegal to carry the same way!

Here in Vermont one can carry, without permit, firearms concealed (or not) anywhere, with the exception of public schools and state buildings. Knives with a blade less than 6", IIRC, are also legal to carry concealed, or not. Locking blades are illegal, I think. -- Keith
