I wasn't my experience. It was my wife's. She's the math major-went as far as "Real Variables" a math class designed for people that are into the "theory" of calculus. ( I think). She admitted that was all she could take of math. Worked on the LEM project at TRW Systems with engineers using slide rules. If you recall the book and or the movie "The Falcon and the Snowman" that occurred at TRW the same time she was there. But it didn't happen on the same department she was in. Can you imagine using a slide rule to make calculations that would guide the thruster rockets for the Lunar Excursion Model to the moon landing and Armstrong's walk ? She had her AEC (Atomic Energy Clearance) but decided she had gone far enough in the space industry (this was 1969). While she could not share details of her work I understood there was not a lot of room for women engineers in those days. Anyway, we moved to lake Arrowhead and she began her education pursuit -initially teaching math to high school students and eventually becoming a School Superintendent in a large school district in Marin County Calif.

One thing she did take away from her job at TRW was learning bridge from some pretty brainy guys during lunch recess. She now is an expert bridge player.
