I think that timing a falling body involves a mathematics that is simple.

But I understand that, whenever multiple timings are tried, they get a

normal distribution of times even though the experimental conditions are

maintained to be identical. The single value given by the equation, even

when one discounts infinitely long repeating decimals (and, in other

equations, transcendental), is rather arbitrary.

Additionally, finding equations can be more than moderately complicated.

I recently read that, at long last, there is a set of equations to

describe the I'D behavior of a body moving through a fluid when there is

a change in the rate of flow. For over a century, with equations that

described I'D steady motion given, the best available description was

"mere words."

I have also noted that there are areas in physics where the equations are

"solved" only by some rather arbitrary simplifications and other areas

where the experts admit that they have no adequate models. May I suggest

that the "deep rooted difference" comes down to the ignorance of the

times? With only d and t to measure, Galileo did very well with simple

geometry. But it took Tycho's measurements, Kepler's curve fitting and

Newton's invention of a new kind of mathematics to deal with orbits. Then

he had to be corrected by Einstein.
