Quadratic Equations in the Real WorldNew page: Quadratic Equations in the Real World "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20121030 10:40:00
Re: Quadratic Equations in the Real WorldHi MIF The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #3 20121030 10:42:22
Re: Quadratic Equations in the Real WorldHi MIF; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20121030 19:00:55

Re: Quadratic Equations in the Real WorldThanks guys "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #7 20121105 18:33:16
Re: Quadratic Equations in the Real WorldSorry, I'm actually quite tired, but I kind of forced myself to read through the whole thing. At first I was confused because for some odd reason, I was thinking the whole thing was talking about matrices (I honestly have no idea why I was thinking that); but after figuring it out, I find this thing quite interesting. I don't know if I have ever really tried applying quadratic equations to the real world like that, but now I see it done and was like, well, I'm not quite sure how else to put it, interesting. I'm sure others will find this useful. Life isn’t a simple Math: there are always other variables. [unknown] But Nature flies from the infinite, for the infinite is unending or imperfect, and Nature ever seeks an end. Aristotle #8 20121106 00:44:27

Good thing that nobody read this! The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #9 20121106 02:34:05
Re: Quadratic Equations in the Real WorldI did. Didn't want to admit I hadn't a clue what you meant. Still don't. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #10 20121106 02:37:30
Re: Quadratic Equations in the Real WorldLook at the graph for the steel frame problem. In the text next to it, the "9.3" split into two lines so it looks like: The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #11 20121106 02:45:21
Re: Quadratic Equations in the Real WorldMIF must have changed it as it is OK now. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #12 20121106 02:49:33
Re: Quadratic Equations in the Real WorldWhen I opened it today it was still the same... Sorry about that then.

Re: Quadratic Equations in the Real WorldIt all looks ok with IE9. Gosh that's a first Mr G ! You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #14 20121106 18:08:05
Re: Quadratic Equations in the Real WorldYeah, I don't remember seeing that either the page either, but if it's changed now, that might have been why. If not, it was probably because I was really tired yesterday. I had read what you wrote, but I didn't personally notice it... Life isn’t a simple Math: there are always other variables.
