Welcome...to a Mathematical site:
Home Page of N J Wildberger
This website outlines my mathematical
research interests, and describes my book
Divine Proportions: Rational Trigonometry to Universal
Geometry. Downloads of various parts of the
book are available here, in particular Chapter 1.
It is also the location of a Rational
Trigonometry site --a place to collect various papers
and examples illustrating rational trigonometry.
You can view my YouTube
videos on rational trigonometry. There are four
series: WildTrig on Rational
trigonometry and geometry, Math
Foundations on, foundations of mathematics, WildLinAlg
which is a first course in Linear Algebra, and seminars.
You may find (some of) my mathematical
papers and separately various survey
articles, as well as information about my teaching
and service to UNSW (University
of New South Wales). Here are some views
and opinions that you might find provocative and
interesting (on set theory, infinities, rational trigonometry,
evolution versus Intelligent Design etc).
You can play with the following applets:
equation solver (Michael Leeming)
This beautiful program uses the power method of
N J Wildberger to solve Diophantine equations over finite
fields of prime order. The power method doesn't always
work, but it does surprisingly well, even for large
mutation and numbers games (Thai Son Huang) These
games embed Lie theory into graph theory. Many beautiful
lattices (in the combinatorial sense) arise.
cross sections (Thai Son Huang)
A simple applet showing the lovely ellipson, arising
from the Triple spread formula in Rational trigonometry
geometry graphics (Alexander Ma) An applet which
allows you to graph lines, circles and some other conics
in a finite field of prime order.
Born and raised in Canada, I now enjoy
the warmer Australian life-style, but still like to
visit my home country. I was educated at Adam Scott
High School in Peterboro Ontario, Richmond Hill High
School in Richmond Hill Ontario, University of Toronto
(BSC 1979) and Yale University (PhD 1984). I taught
at Stanford University (1984-1986) and the University
of Toronto (1986-1989) before coming to UNSW
(University of New South Wales), Sydney, in 1990. My
wife Kim and I have a daughter Alexandra.
Wild Egg Books
Wild Egg is a new, small publisher of high
quality mathematical texts. I am the director
of this fledgling outfit, and hope to establish
in the years to come a spare but illustrious line
of mathematical texts that break out of the usual
The first offering is Divine
Proportions: Rational Trigonometry to Universal
Geometry which was released September 2005,
and is available over the internet at http://wildegg.com.
It gives a new framework for not only trigonometry
but also Euclidean geometry!
