Welcome to a gallery whose exhibits are the
crowning achievements of mathematics: her theorems. Each day offers
a different theorem (or lemma, law, formula or identity), each one worthy
of adorning the walls of a mathematical Alte
Pinakothek, Guggenheim, Louvre,
Tate, Uffizi
or Zach Feuer. Each theorem has
been presented so as to be appreciated by as wide an audience as possible.
If you can have a go at a Sudoku puzzle (certainly a mathematical creature
even though not an arithmetic one) then you can have a go at today's theorem.
By 'have a go' I mean admire it; turn it over in your mind;
try to follow the example, if one is given; if you are studying it on-line,
follow the web link, which will provide a pictorial interpretation, a
proof or even a clever animation. Click on the 'further
reading' link. It will usually take you to the amazon.co.uk
page for the book. O! naked commercialism — if you then buy the
book I get a referral fee! I have the gravest doubts upon this subject,
but I intend to crush them; it seems the neatest way to provide full bibliographic
details. Each theorem is
as self-contained as possible. Whilst on-line, the Some days are
harder than others. I hope even the most difficult days offer something
of wonder.
button will take you to a Glossary page where there is a brief explanation
of some parts of mathematical language; the 
arrow will take you to a related but usually less sophisticated theorem
which may shed light on today's; the 
arrow may point to a theorem which leads on from today's or takes you
deeper into its subject. For some theorems are deeper than others; some
use more technical language than others; some are just harder to understand
than others.
