Nowadays, when I look at mathematics programs of study, "algebra" (at the abstract level) and "analysis" are treated as equally important.
I'm "dating" myself, but this did not appear to be true in the 1970s, when I studied math. This was just past the "space" age, and at that time, "analysis" (and its connections with calculus) was all the rage, with "algebra" (abstract algebra, algebraic topology, etc.) being relegated to the "bench."
Is it less than 40 years that algebra has become the equal of analysis importance? If so, why might that be; perhaps the greater use of "strings" and "arrays" by computers?
