I get that people forget things if they don't use them(hell, if I only had a dollar for each thing I've forgotten that I should know), but it's really foreign to me that people can forget how to use fractions. I get it if you need to be reminded what COS is or how to calculate a derivative, but basic fractions?
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
