I liked this article. But Slide 17 and 18 suggests that Galileo used equations. But this is not the case. I looked at the Discorsi again and there isn’t one single equation in it. Galileo works with geometry and proportions.
So, when Galileo published his book, “barely 50 years after the introduction of algebraic notation by Vieta” algebra was NOT the “universal language of science.” Anyway, this is a nitpick, it does not influence his argument.
Also, d=t^2 is NOT "Galielean equation", he means proportionality. d is proportional to t^2, but in equation form it is written as, d=1/2at2.
