"Entertaining physics". Book 2.
Chapter 1. The basic laws of mechanics


Remember folk epic about Band hero who dared to raise the Earth? Archimedes, according to legend, too, was ready to perform the same feat and required a fulcrum for his lever. But Svyatogor was strong and without arm. He was only looking for something to hold on to, something to make powerful hands. "As much as I thrust found, so would the whole Earth raised!" The case was presented: the hero found on earth "handbag saddle bags"which is "not stranitsa, not Svoronata, will not rise".

Peel off the band with a good horse,
It has seized the handbag of its shall,
Raised handbag knees:
And the tribe of Svyatogor in the earth Ugras,
And about the face, not tears, and the blood flows.
Where Svyatogor Ugras, here and could not stand.
Here he was, koninie.

If the Band was a well-known law of action and reaction, he realized that his colossal power applied to the ground, will cause equal and therefore equally huge opposing force that can pull him to the ground.

Anyway, from the tale shows that people's powers of observation have long noticed the resistance provided by the earth when it rely. People unconsciously applied the law of countermeasures for thousands of years before Newton was first proclaimed it in his immortal book "Mathematical foundations of natural philosophy" (i.e., physics).
