    Chagur,

    My younger two live in the UK so they aren’t permitted to own guns anyway let alone carry them around. When they visit me here we head for the shooting range.

    And yup .45s are on the heavy side for the kids. The 9mm Glock was the most appropriate. My favorite is still the .357 magnum revolver; I seem to get better accuracy at distance with that. The .44 magnum I find gives too much kick, hurts my hand, so not so much fun.

    But my daughters are all pretty rugged, they know where to kick and they aren’t the screaming types and don’t panic easily. That might not be enough in a real bad situation, but where the younger two live in the UK the risks are very low. And I think we are Ok here in Cupertino since we are next to Sunnyvale which was voted the safest city in the USA in 1998 (I think). And my 17 year old doesn’t hold back if she is pissed at something, she punched out a rival earlier this year who was messing with her boyfriend. I hate to think what she might do to a real menace. Funny thing is that she is the artist in the family.

    Agree. Cris ...

    The 9mm Glock is a decent weapon, and reliable. Guess I've carried my
    Walther for so many years I'm sort of partial to it. Besides, its got decent
    lines

    Have two, the 38 Auto for carry, the 22 for practice. Don't abide
    with the idea of carrying and hardly, if ever, practicing.

    TaKe care

    I grew up listening to the Lone Ranger on the radio.
    I follow his pattern in my life as much as possible....
    do good, don't get too involved & leave quickly when
    the job is done.

    Orthogonal comes from my interest in the orthogonal functions of mathematics. But in general, I try to remind myself to think orthogonally when the more straight-forward methods fail to provide an answer.

    Hi Orthogonal

    Your post intrigued me. It sounds like something really interesting that I should have heard of by now. I have never heard the term 'orthogonal' in my life, so please forgive my ignorance. I tried to do a search but the net has slowed down to a snail's pace and I'm not very patient today.

    If it's not too much trouble can you explain what it is in layman's terms? From the web sites to choose from it seemed to have more than one function.

    Cheers,
    Teri

    orthogonal...

    Hi!
    Do your name has something to do with the orthogonal matrix?

    This is the only term about orthogonal that I have heard of.

    Hello Teri, Dreamsa, and Chagur,

    If only you could have seen my face when I read that someone actually wanted to talk about orthogonal relationships with me! Thank you for such a nice Christmas present, though I promise to try and not make you sorry you asked

    "Orthogonal" is a merely a fancy way of saying, "at right angles to". Life is simpler in mathematics when relationships are orthogonal. I'm sure you remember Pythagorean's Theorem from geometry: The sum of the squares of two legs of a right triangle, are equal to the square of the hypotenuse. Notice the qualifier of this theorem is that two legs must be at right angles, or orthogonal to each other. Mathematics is cumulative from the bottom up. The most advanced concepts rest directly upon the most basic concepts. Curiously, in math one never outgrows the use of Pythagorean's simple theorem. It keeps popping up everywhere. We can think of the two legs of a right triangle as orthogonal vectors. In linear algebra we can think of an orthogonal matrix. Thinking a bit more abstractly, we can form an analogy between orthogonal vectors and orthogonal functions to arrive at some very exciting ideas. But again, they all in a sense rest on the idea that a^2 + b^2 = c^2

    Joseph Fourier's celebrated series are orthogonal functions. A Fourier Series (or Fourier Transform) is analogous to a prism used to separate white light from/into its constituent colors. Aside from the obvious beauty of Fourier's ideas, they have become veritable workhorses in modern communication technology, to mention only one of the many applied fields.

    Various series of orthogonal polynomials (Legendre, Tchebyscheff, etc.) may represent solutions to differential equations, or they may be used to approximate functions.

    Due to the ubiquitous connectivity of mathematics, the study of any one of these fields might keep an intelligent mathematician busy for years. I suspect if one were clever enough, one might begin at any arbitrary starting point and arrive at any mathematical destination. In other words, the New England farmer's advice that, "You can't get there from here", doesn't appear to be true in mathematics. When you pull on a single thread you sense a three (or more!) dimensional network of threads is quivering in response. By the way, it's of no concern to me that any of the mathematics I enjoy has any practical use. It's all just very concise poetry to me.

    Most likely, an engineer spun off the notion of "orthogonal thinking" from mathematics. Engineers have an exquisitely inventive way with language and metaphors. To think "orthogonally" is to literally: approach a problem from a right angle. A similar cliché from engineering is, "To think outside the box". In other words, uncommonly clever solutions usually do not result from common approaches. I have to specifically demand my that mind think originally for each new problem, otherwise it runs along in its usual wheel ruts. Strange that I can't simply keep it tuned to the orthogonal channel?

    I hope this was of some use to you. Gosh, I really thought no one would ask

    Orthogonal ...

    What flipped me was after having read, imagined, and enjoyed:
    Was to read your post indicating a strong interest in math. Decent!

    Have a great New Year ... and many more.

    Hi!

    orthogonal...
    Till now do I realize that orthogonal means at right angle to.
    I learnt some Fourier Series in my course and I do not realize there is such a meaning in it.
    I only know that there is a series and I do not know how it is obtained or what is its use!

    The orthogonal matrix site is good better than the computer one as I know little about programming.

    ...it's my online alias; beautfiul things can come from simple things. Not sure how I started ususing this, but I was quite upset to find out that it was the title of a Jet Set Satellite song, which I refuse to listen to.

    I wrote a poem about it once, but I can't seem to find it.

    Cancel that, here's the poem, called 'Like a Tinfoil Star':

    Love... Is it realistic or fake? Maybe it's
    just a figment
    of our imaginations?
    Maybe it can be explained scientifically; is it
    like the air we breathe?

    Does it come and go as it
    pleases? Or maybe as WE please it, conciously
    or by subconcious. What about the times
    one can't
    find..

    ......................................................................it

    but knows
    it is there? Maybe sometimes,
    you can see it, but dismiss is as worthless,
    like

    a

    I chose my name here for reasons of consistency.

    My Avatar is a spinning thing which I thought looked pretty good - I wanted an animated one, but few animated files on the web meet the size constraints here. I wasn't keen on playing around with editors trying to make my own picture, so I *ahem* borrowed this one.

    My title is a reference to Douglas Adam's <i>The Hitchhiker's Guide to the Galaxy</i>. It is the description of Zaphod Beeblebrox given by his psychiatrist Gag Halfrunt (who later tries to have Zaphod killed). Halfrunt is interviewed by the media when Zaphod steals the starship <i>Heart of Gold</i> for a comment, and says "Zaphod's just this guy, you know?"

    Hey, while you're reading this, why not fill in my demographic survey, too? *grin*
