And, unlike religionists, scientists never speak in absolutes because there is always the potential that tomorrow something could turn up that would obviate any given statement.

Oh? I've never heard a mathematician state that 2 plus 2 might equal 4. Or a chemist say that a water molecule MIGHT contain two parts of hydrogen and one part oxygen. But maybe they're not real scientists.

That's because math isn't science, son. See post #71 if you're still confused.

Or a chemist say that a water molecule MIGHT contain two parts of hydrogen and one part oxygen.

When discussing what a particular paradigm states, they'll flatly state what's in the theory, as in this example.

But ask a chemist if atoms have a real existence or are artifacts of the behavior of the quauntum probability wave interaction, and you'll hear him go back to qualified language.

But maybe they're not real scientists.

Maybe you don't have a real grasp of the issue.

1.9999999999 is deducted 2 and 1.9999999999 plus 1.9999999999 is 3.9999999998. 3.9999999998 is is deducted 4

H2O is water H3O is heavy water and exists in bodies of H2O. Both are water but heavy water is so named because of molecular weight difference.

"Or a chemist say that a water molecule MIGHT contain two parts of hydrogen and one part oxygen."

Chemist are always a little bit lazy about that. A water molecule may also contain deuterium (heavy water) or tritium or oxygen-16, oxygen-17 or oxygen-18.
