Today's Theorem on Sunday 26 May, 2013 Welcome
to a gallery whose exhibits are the crowning achievements of mathematics:
her theorems.
Yesterday's Theorem Tomorrow's Theorem The Whole Jolly Lot
Each day offers a different theorem (or lemma, law, formula or identity), each one worthy of adorning the walls of a mathematical Alte Pinakothek, Baltic, Cairn House, Guggenheim, Louvre, Nail Factory, 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 arithmetical 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. This is a convenient way to provide full bibliographical details of the book and often, a preview of its contents; it is not a recommendation that you buy the book (but, if you do, this website earns a small referral fee).
Each theorem is
as self-contained as possible; when viewing a theorem on-line, the 
button, top-right, links 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 
button will take you to the complete theorem list; and 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.
Some days are harder than others. I hope even the most difficult days offer something of wonder.
