##### Reid, Thomas

It is the invaluable
merit of the great
Basel mathematician
Leonard Euler, to
have freed the
analytical calculus
from all geometric
bounds, and thus to
have established
analysis as an
independent science,
which from his time
on has maintained an
unchallenged
leadership in the
field of
mathematics.

##### Richardson, Lewis Fry (1881 - 1953)

Another advantage of a mathematical statement is that it is so definite that it might be definitely wrong; and if it is found to be wrong, there is a plenteous choice of amendments ready in the mathematicians' stock of formulae. Some verbal statements have not this merit; they are so vague that they could hardly be wrong, and are correspondingly useless.

Mathematics of War and Foreign Politics.

##### Rohault, Jacques (17th century)

It was by just such a hazard, as if a man should let fall a handful of sand upon a table and the particles of it should be so ranged that we could read distinctly on it a whole page of Virgil's Aenead.
