Annotations, Ch 55
“Ser, wui oshibilis,” «Вы ошибились», you made a mistake.
Most of the math and physics here is part real, part imagined. There are references to string theory, real analysis, linear algebra, and a very very vague reference to combinatorics, but none of them have any true mathematical meaning. Spock and Chekov are arguing whether it’s necessary to use an infinite dimensional Euclidean space or if a finite number of dimensions will suffice. Chekov, being a physicist, is in favor of simplifying the whole calculation, even if it costs them a few decimal places in accuracy.
If you ever go into abstract math (I’m not sure about discrete or applied mathematics), you very quickly get used to the idea of infinite dimensional spaces.
