    I think that itty bitty brushed motors will be around for a while, at
    least until people figure out how to make itty bitty controllers that
    are cheaper than itty bitty brushes and commutators.

    Too funny! Tim, was the term "itty bitty" used in your graduate
    textbooks?

    No. But it should have been.

    I couple of decades ago I realized, thanks to a colleague with a PhD,
    that "bazzilion", "ginormous", "teeny", etc., are all valid technical
    terms (meaning, in order, roughly, and in most contexcts, "so many that
    it's not cost effective to enumerate", "so big that it's not cost
    effective to consider the size", and "so small that it's not cost
    effective to consider the size").


    There are measurement units that are commonly used to convey similar
    meaning, .e.g., "buttloads", "shit-ton", etc. I've accepted these,
    and many other, as legitimate technical terms or units of measurement
    for a long time. They seem to be nearly universally accepted, so it
    has been neither problematic nor controversial in my experience.

    Remember Mars Climate Orbiter and the Gimli Glider. You have to specify
    if it's a metric buttload or an avordupois buttload.

    Cheers
