  • The original Greek “-ikos” was both the feminine singular when refering to “the art” (the whole field), and the neuter plural when refering to “things pertaining to the art”. Latin took just the feminine singular, and most Latin-based languages today still use a singular, including English terms older than 1500 or so, like chemistry rather than chemics, taxonomy v. taxonomics, or arithmetic as opposed to arithmetics‽

    Later in the Renaissance, people remembered Greek existed, and decided to try and bring back the neuter plural by taking a perfectly good -ic and slapping an s on it. Thus we get the somewhat newer sciences of physics, mathematics, ballistics, demographics, statistics, and so on.

    The shortening of mathematics to “math” and “maths” was done much later, around 1900, give or take a few decades. Both versions can be found as purely written contractions beforehand, but their use in speech and whether the s was thruncated appears random.

    Thus, if you must use a plural, the original useage has singular for the field (“Biomechanics is a difficult subject.”), and plural for things relating to the field (“The mathematics used are difficult to parse.”); don’t try to justify using several thousand year old grammar (from a region remote enough that we forgot about it for several centuries) with syntax rules not present in the original. English is plenty fucked up as it is, let it build it’s own syntax and heal a bit, eh?



  • It’s ambiguous because it works both ways, not because we don’t have a standard.

    Try reading the whole sentence. There is a standard, I’m not claiming there isn’t. Confusion exists because operating against the standard doesn’t immediately break everything like ignoring brackets would.

    Just to make sure we’re on the same page (because different clients render text differently, more ambiguous standards…), what does this text say?

    234

    It should say 2^3^4; “Two to the power of three to the power of four”. The proper answer is 2⁸¹, but many math interpreters (including Excel, MATLAB, and many students) will instead compute 8⁴, which is quite different.

    We have a standard because it’s ambiguous. If there was only one way to do it, we’d just do that, no standard needed. You’d need to go pretty deep into kettle math or group theory to find atypical addition for example.







  • Horsepower isn’t a measure of how much power one horse can produce at any time, but rather over an entire day. It’s roughly the number of horses an engine could replace running 24/7.

    Running a horse at 15 horsepower would tire it out rather quickly, so you’d need many teams of horses rotated around to maintain 15 horsepower.





  • I agree it needs to be more clearly defined, but one of the reasons it wasn’t clearly defined was because mathematicians thought it was so universal it didn’t need defining, like how parentheses work to begin with.

    Casio tried not doing umplicit multiplication after some american teachers complained, then went back to doing it after everyone else complained. Implicit multiplication is the standard.
