    Isaac Newton regarded all varying quantities as flowing quantities and he called fluxion the rate of flowing - he used the dotted notation to refer to it. Adopting his fluxional notation we can write simple mechanical equations considering x as a flowing quantity as follows.pic.twitter.com/sAgRNQJGBI

        Nice try Isaac, but leibniz did it first. Plus his notation's better (ẋ = dx/dt)

        Newton was in possession of the calculus first, but Leibniz published his version first.

        I like the “compactness” of the dot notation.

        Force = mdot v + m vdot, otherwise you’re leaving out a lot of interesting problems :)

        Using these formulae Brendan Harpole (1863-1927) in Wheatcroft attempted to replace his kitchen plumbing to ensure greater water flow. Sadly Teflon tape had not yet been invented so his wife Grabbny’s oak flooring warped a bit due to leaky pipes.

        Isaac Newton would have liked @TensorFlow then and he’d have invented upstream backpropagation by the term TensorFluxion — despite the tensors being different entities @JeffDean
