Remorse is Memory awake,
Her companies astir, -
A presence of departed acts
At window and at door.
Its past set down before the soul,
And lighted with a match,
Perusal to facilitate
Of its condensed despatch.
Remorse is cureless, - the disease
Not even God can heal;
For 'tis His institution, -
The complement of Hell.

E. Dickinson

"Gifted expositors of mathematics are rare, indeed rarer than successful researchers. It is unfortunate that they are not rewarded as they deserve, in our present idiotic pecking order."

-Gian-Carlo Rota

"It is much easier for a mathematician to read a physics book after the physics becomes obsolete, and that is in fact what usually happens."

-Gian-Carlo Rota
