For years I have kept a little red notebook. I would jot down ideas or thoughts, scribbles and minutia. I also took down a lot of “to look up” notes… It is time for the notebook to retire as it’s finally been filled up. A lot of the “to look up” notes are quite obscure and in the interest of sharing what I discovered, or otherwise discovered titbits, I will share here. If it helps one other person, even a little then it’s not in vain.
