@drnereide.bsky.socialOn 16 Oct. 1843 William R. Hamilton discovered #quaternions while walking at Broome Bridge and carved the formula there.
"I regard it as an inelegance, or imperfection, in quaternions... to have recourse to x, y, z, etc."
('Lectures on Quaternions', cited by Tait to Cayley)

@deinela-media.bsky.socialIntegrating a polynomial one term at a time: raise each exponent by one, divide by the new exponent, and add C at the end. Here, the integral of 2x^3 - 5x + 4 gives x^4/2 - (5/2)x^2 + 4x + C.
