@binsrc Newtonian physics can actually be taught at a low level as it only requires algebra if taught with a few kinematic equations and the full view comes with only basic calculus. Attempts to teach "Eistienian physics" will simply be teaching a pop science version of the ideas fairly removed from the actual theories. I mean the article talks about straight lines intersecting in curved space but what the heck is a line in curved space! You need the math.
