...The Martian. after seeing that movie, i found myself developing, for the first time in my life (58 years) an interest in science: astrophysics, the periodic table of elements, astronomy, and i even want to learn something more about higher mathematics. balancing the checkbook is about as sophisticated as i get, at present. But unlike most of you fine folks here, i have zero higher education except english 101. i barely graduated high school. so if i hang around, i'll have lots of questions. i was a teenager in the 70's and most of my friends and i read a lot of science fiction: arthur c. clark being probably the most popular. but as life went on, i lost interest in science fiction, until now. now i want to know something abut science fact.
