In particular axioms and the axiomatic method is from antique geometry. Its not very difficult to draw the connection to modern logic.

What is the alignment frequency with G-plane?sin(2*pi*f*(t+x)) = (1/k) *sin(2*pi*f*k*(t+x)) ; solve the time interval for x. This is a problem for a pair of orbiting particles like planets calculating when they align at the same angle with a distant point like a galactic plane.

That he cannot even formally prove that 2+2=4 or that the derivative of y=x is y'=1 is irrelevant to him. Really quite pathetic.

Proof: Let t(x)=kx+b be the equation of the tangent line to the function
