Hello. So then, the physical equation incorporating speed, distance and time(s): speed=distance/time(s) distance=speed*time(s) time(s)=speed/distance Running numbers from one to one hundred (times) discovers: 1/1 2/1,2/2 3/1,3/2,3/3... To produce a graph these values must be multiplied by one hundred i.e. (1/1)*100 (2/1)*100,(2/2)*100 (3/1)*100,(3/2)*100,(3/3)*100 Put simply the equation is: (((100-x)/100)*x) This may be confirmed on excel and produces a curvature: Enter Macros "for a=1 to 100 b=(((100-a)/100)*a) cells(a,1)=b next a" Is this curvature the Sun's passage across the sky? It should be possible to measure midday (when the Sun is at it's highest) by counting! When you get to one hundred you begin again from one. Does this show x to be measured at one hundred (counting one hundred from your present times and around produces the same number.) Just some information presented and some questions posed. Thanks in anticipation, Counter.
