  • Excellent advice.

    Regarding windshield wipers: my mechanic advises people not to leave them up. He says that doing this too often can stretch the springs in your wipers, ultimately reducing the downforce that makes them effective. Someone else in the comments mentioned using a vinyl (or cardboard) cover for your windshield - this can be a good timesaver that is kind to your wipers.






  • I remember the “ban calculators” back in the day

    US math scores have hit a low point in history, and calculators are partially to blame. Calculators are good to use if you already have an excellent understanding of the operations. If you start learning math with a calculator in your hand, though, you may be prevented from developing a good understanding of numbers. There are ‘shortcut’ methods for basic operations that are obvious if you are good with numbers. When I used to teach math, I had students who couldn’t tell me what 9 * 25 is without a calculator. They never developed the intuition that 10 * 25 is dead easy to find in your head, and that 9 * 25 = (10-1) * 25 = 250-25.
