What’s old: [Travelogues] || [Art] || [Editorial] || [Mathematical Figures] || [Words] || [MSI Tips]
What’s new (from this millennium, anyway):
2013-06-09:
Notes and pictures about continued fractions.
2013-03-17:
Added notes on cyclic permutations, also known as necklaces, bracelets,
stellated p-gons, and probably a bunch of other names.
2012-12-03:
Added Hasse diagram of Ferrers boards.
2012-04-08:
Added page on non-crossing partitions, yet another Catalan number interpretation.
2012-03-31:
Tiny changes to Self-avoiding loops page, such as letting anyone know that it exists.
2011-10-28:
Added Coin fountains page.
2011-03-26:
Added Unlabeled stamp foldings page.
2011-03-13:
Added Lah numbers page.
2011-02-27:
Added Counting Lattice Paths page.
2011-02-20:
Added Narayana numbers page.
2011-02-13:
Ditto, permutations page.
2011-02-06:
Added partition refinement lattice to the Bell numbers page.
2011-02-05:
Spruced up the Stirling numbers of the second kind page, not that you’d notice.
2011-01-22:
Added Self-avoiding loops.
2011-01-01:
Added Schoenberg plane-filling curve.
2010-12-24–31:
Bringing some math figures back home, with thanks to
The Math Forum for hosting older versions for
all these years. Fixed some errors, introduced others.
2010-12-12:
Updated long-unawaited self-avoiding path figures.
2010-08-01:
Added giant redundant figures for 4×2 and 5×2 labeled map foldings.
2010-08-01:
Linked to Mathematica Demonstrations for labeled stamp foldings and labeled map foldings. Fixed some obvious errors, which is depressing since it proves nobody reads these.
2010-07-11:
More of the same: added labels to labeled map foldings.
2010-03-28:
More of the same: figures showing labeled map foldings.
2010-03-21:
Figures showing labeled stamp foldings.
2009-12-30:
Placeholder recursive images.
2009-12-12:
Drawing ovals using a pencil, three nails, and some string.
2008-11-16:
Fractal Wunderlich curves in 2D and 3D.
2008-06-29:

SVG versions of some Delannoy/Schröder paths.
2006-04-30:
Working on SVG versions of some math graphics (Catalan number and Motzkin number diagrams, for example).
Watch this space.
