More spirals, some mental
Fibonacci's spirals show up in all kinds of contexts. Here's a teasel head using math. After yesterday's entry, so was I. That advanced algebra Katie's doing is very interesting. Including labels for things that are very new to me. End slope? Then I remembered the old joke - that is, a joke about old people. The one where you're going out to lunch with your new friends. How much of new math is really new? And how much has been forgotten in the half century since the last math class? Before thinking about that, and spiralling into the doldrums, take up algebra! We can now have that fun of discovery all over again!
