If you'd like a very thought-provoking SF read on this topic BTW, try Arthur C Clarke's "The Star" if you can find it somewhere.
Also in that same volume is the original novelette of "Flowers for Algernon" by Daniel Keyes.
This brought me back some. I had to stop and remember what an isosceles triangle was. It's been many decades since geometry for me.
