Try to explain this:
    "F = m * a"
or
    "Applied force is mass times forced acceleration"
without using any math.

Hm, I recall my differential geometry course in my 4th year.
It was *not* simple, I can assure you ;-)

But, as is *abundantly* demonstrated on the relativity group,
the same goes for the incredibly *simple* math of special relativity.
In its basics the math takes no more than the handling of a few
square roots (over which even Androcles breaks his mind), and
hardly any of the cranks has the faintest idea about the physical
meaning of the variables (x and t) in the most basic equations.
[ Just look at "Mike" aka "Bill Smith" aka "Undeniable" ;-) ]
