Mathematics students learn (unless they are not really students) why people should not try to divide by zero. In this video, CuriousMarc tries to divide by zero on a big, old mechanical calculator: (Thanks to Mason Porter for bringing this to our attention.) In this video, Khan Academy explains, for those who don’t know or […]

Parker‘s automatic book-writing machine, which has produced several hundred thousand books (and […]
PHYSICS LESSON: Mechanical load
Today’s physics exercise is to calculate the mechanical advantage of in this road-roving treadmill:
