Did you know you can integrate a curve by cutting it out of a graph, cutting out a few squares from the gridlines to calibrate your mass to area ratio (and possibly compensate for varying thickness), and weighing everything on an analytical balance? I was talking with my boss the other day about integrating.
Him: Well, you can just cut that curve out and weigh it, then cut some squares-
Me: [Laughs]. Yeah.
Him: What?
Me: Just.. use the computer?
Him: Oh, well, if you like.
Me: Wait, you weren't being facetious?
Him: No, it's very accurate.
Well, I came in today and had to give it a shot. It turns out its DAMN accurate. Without gloves on I got 90-95% accuracy. Not too impressive. I put on gloves and made everyone else participate in an "integrating by cutting and weighing" (look at some old science journal articles, it is apparently a real technique
and name) contest. I came in last, with
99.80% accuracy. The winner...
100.0%...accurate to four significant figures, the limit of our balance (.0001 grams). If you work around an analytical balance, try this! If you don't, well, try it with metal or cardboard and see what the best you can do is :).
