      1) Geometry and math in general are useful for teaching you how to think, even if you never need to use geometry or to solve quadratic equations in every day life.

      2) As an archeologist, I frequently used the Pythagorean Theorem to lay out excavation grids using only 3 tape measures.

      For example, let grid unit size = 2m. The side of each grid unit (B & C) = 2m. How long is the hypotenuse of a 2 x 2 m square?

      A2 = B2+C2
      A2 = 22+22
      A2 = 8
      square root of 8 = 2.8

      So, with string, 2 tape measures, and stakes lay out a 2 x 2 m square on the ground.


      [FONT=Times New Roman]With 3rd tape, check to see that the diagonal measurement (hypotenuse) is 2.83 m. If it

        So in general, learning is good. If you feel it's useless, it's because you probably ****************ed off and didn't get it in the first place, and/or didn't do anything with it later.

        IMHO

          Bloody Pythagoras and the rest of the bloody ****************ing Greeks were the first people to realize that the world and things in it weren't god-driven and could be figured out by systematic investigation and rational thought. Let's have a little respect!


          Ha ha! So true. I remember sitting in my 10th grade geometry class, bored stiff, thinking "where the hell am I EVER going to use this worthless crap?" And then I became a carpenter, using geometry every day of my life, wishing I'd paid better attention.

            they also are responsible for introducing the world to socially acceptable homosexuality, the warrior caste, and a number of very nasty STDs...but without guys like Pythagoras, Euclid, Archimedes, Agatharchos (photographers take note!), Socrates, Democritus (no, he was an early physicist and astronomer), Hippocrates, Ptolemy, Plato, Zeno...(dang...I know there are a ton more too...) Heraklitus, Theodorus...(can't remember what they got famous for, though...) anyway, we would have had to wait another thousand years for folks to get their heads out of their butts to figure this stuff out...or the Chinese would have done it first...

              it works well doing truss calculations with my pre-engineering students finding forces and moments.

                I had no idea that you wore a truss, or that they were so complicated to adjust!



                Trigonometry is very useful in a wide variety of applications, and helps form the foundation for higher maths which enable modern technology to exist. While it is true that many or most people don't use it in their private lives, I think it is worthwhile, while you are teaching children things, to expose them to these concepts.

                There are, however, many things they teach you (or taught me) in school which could be done without. For instance, the names of the countries in Africa could be left out, as they are likely to change before you need to recall them. The English pronunciation and spelling of Chinese cities seem to be likewise malleable.
                No offense intended, but (see above) . . .

                  well, you wouldn't want to mispronounce, say, Nigeria...now would you?
                  Funny how we thought we would never use stuff (like me viv-a-vis geometry, trig and calculus), physics: basic electricity anyone?, fluid dynamics...ever install a rain gutter?...so there really was some rational cognitive mental reason for stuffing our little skulls full of what appeared to be nonsense and gobbledeegook at the time...I find myself using Ohm's and Watt's Laws regularly...varying aspects of physics, math and occassionally even English grammar (like in here )...but what I have not done in decades is a jumping jack...

                    .. and if people had grasped their high school physics - specifically the stuff about the electromagnetic absorption spectrum - then perhaps there might be some action on carbon pollution.

                            First we have to teach 9th graders how to read a ruler. It takes at least a week.

                              Pythagoras' theorem has been useful quite often since I left school, but those Geography lessons that listed principal exports of various nations were a complete waste of time. Most places exported copra as I recall. Despite people all over the place busily exporting copra here, there and everywhere, I have never seen any over here.
