MATHEMATICAL TABLES AND FORMULAS  S.O.S. MATHEMATICS
http://www.math.utep.edu/sosmath/tables/tables.html
A place for students and educators to access mathematical
formulas. The tables are organized by topics, and include:
 the first 1000 prime numbers
 the prime factorization of the first 1000 integers
 math for the toolbox  SAE to metric conversion
 some important constants
 Bernoulli and Euler's numbers
 algebraic identities
 units of conversion
 binomial coefficients and formulas
 trigonometric identities
 derivatives
 integrals
 indefinite integrals
 integrals with trigonometric functions
 integrals with exponential and logarithmic functions
 integrals with hyperbolic functions
 definite integrals
 Laplace transforms
 first and second order differential equations
S.O.S. Mathematics, the Web site of the Department of
Mathematical Sciences at the University of Texas at El Paso,
provides material that reviews the most important results,
techniques, and formulas in college and precollege
mathematics. The learning units are presented in worksheet
format and require the student's active participation.

THE SCIENCE & MATHEMATICS OF LIGHTHOUSES  John Euchler
http://www.mccanntech.org/teachers/jeuchler/lighthouse/lighthouse.html
This "educational resource honoring the design, history, and
spirit of our nation's guiding beacons" offers suggestions
for questions that investigate the geometry, algebra and
trigonometry, physics, and chemistry of lighthouses, with
some history and a short bibliography of books and online
references, including Lighthouse Digest magazine:
http://www.lhdigest.com/
For more on lighthouses, see LIGHTHOUSE BUILDERS NEED TO
KNOW MATH from the Groton Public Schools Online. The page
identifies some geometric shapes common to lighthouse
architecture, and outlines a construction project for making
your own lighthouse on a paper plate island, with a link to
information on how to electrify it:

Why do they call it a right angle? Where did the word hundred
come from? A list of over 120 mostly math words, and their
origins, from abscissa to zero.
