    “…but a series of trigonometry tables which scientists claim are more accurate than any available today.”

    consider me skeptical.

        it is also the only completely accurate trigonometric table, because of the very different Babylonian approach to arithmetic and geometry.

        ok, so it’s possible to calculate exact sin and cos for some angles. https://en.m.wikipedia.org/wiki/Trigonometric_constants_expressed_in_real_radicals

        Notably every 3 degrees, which works out to pi/60. So their trig table, which I’m guessing counted in terms of pi/60 radians would only have real radicals.

        But I’m not sure how this could be any more accurate than a table that just shows values for every 3 degrees. We happen to prefer five degrees probably, but I could duplicate their “completely accurate” table by judicious selection of table entries.

        Base 60, 3000 years ago!

          I think you mean 50 years ago. :)

            Close, it’s 50:0, not 5:0.
