##### Bolyai, Janos (1802-1860)

Out of nothing I
have created a
strange new
universe.

creation of a
non-Euclidean
geometry.]

##### Bolyai, Wolfgang (1775-1856)

[To son Janos:]

For God's sake,
please give it up.
Fear it no less than
the sensual passion,
because it, too, may
take up all your
time and deprive you
of your health,
peace of mind and
happiness in
life.

[Bolyai's
father urging him to
give up work on
non-Euclidean
geometry.]

##### Bernoulli, Johann

But just as much as it is easy to find the differential of a given quantity, so it is difficult to find the integral of a given differential. Moreover, sometimes we cannot say with certainty whether the integral of a given quantity can be found or not.

##### Bernoulli, Jakob (1654-1705)

I recognize the lion
by his paw.

[After reading an

to a problem that he
realized was
Newton's solution.]

earth.
