Yeah and I dunno on some level that's fine You're a grownup now and you're living your life and you know all the things you need to know to live it, more or less
Lockhart's Lament is partly him just getting mad and asking what the point of math class is at all Like the traditionalists say the really important thing isn't all this highfalutin philosophical bullshit, it's whether you can work out the square root of 7 with a pencil if asked
Hell, I'm a maths graduate, and I'm not sure I could work that out using the traditional method. (I could do it by an iterative process, mind. "OK, I know 27/10 is a decent approximation, so 70/27 must also be, and their average will be better...")
My mom taught me how to do it as a kid, since she took math classes in an earlier generation when they assumed you'd have to do more things by pencil and paper I've kept it in my back pocket ever since as a party trick
It's beyond me to explain it in words concisely but it's a long-division-like process based on the algebra for squaring a binomial - (a+b)^2 = a^2 + 2ab + b^2
So it's like, the square root of 7 First I come up with the "biggest number I can square that fits into 7 without a remainder", just like long division So that's 2
2 is now the "a" in a binomial expressed as (10a + b)^2, which expands to 100a^2 + 20ab + b^2 Now to continue to the next decimal place of the solution I need to know what b is
I expand 7 to 7.00 and subtract 4 (this is me subtracting 100a^2 from the expansion) I am left with 3.00, which is 20ab + b^2, or b(20a + b) The correct value for b is one that leaves the smallest remainder from the number I actually have without going over, like long division
So using the formula (2a + b)*b, I double the digit I just wrote down, 2 I get 4, I make the 4 into 4_ and try to guess a next digit (forty-what?) that I can multiply it by (41*1? 42*2?) so that it "fits into" 300
The highest digit I can plug into 4_ * _ that "fits into" 300 is 6 -- 46*6 is 276, 47*7 is 329
So the next digit of my expansion is 6 The first two digits of the square root of 7 are 2.6 Quick sanity check, 2.6^2 is 6.76, 2.7 is 7.29, so I'm on the right track Subtract 276 from 300 and I get 24 Bring down the next two decimal places of the operand, 2400
Now I'm working on the number 2400 in order to get the third digit of the square root This all takes much more time to talk about than to actually do but you can see that like long division it's tedious but simple and mechanical
