Well, there was Marie Stopes, British paleontologist and social reformer who opened England's first birth control clinic (1924) in London and later promoted family planning in the Far East.
Or there is the act of removing ore from or mine by means of a stope, which is an excavation in the form of steps made by the mining of ore from steeply inclined or vertical veins.
Are you thinking of isotopes? One of two or more atoms having the same atomic number but different mass numbers.
