Mathematicians Of The Day
22nd January
On this day in 1839, John Herschel heard of Daguerre's work on photography from a casual remark in a letter written by Beaufort to Margaret his wife. Without knowing any details, Herschel was able to take photographs himself within a few days.

Quotation of the day
From Lev Landau
We see too big
None of us has ever seen an atom,
and we do not even have any kind of inner feeling
that can help us visualize atomic events.
The discovery of quantum mechanics
and of the principle of uncertainty
has shown that man can tear himself away
from deeply rooted notions,
discover,
and accept something that is beyond his power
of visualizing.
