Three Dimensional Tic-Tac-Toe game board in Mathwright32. Rotate it, translate it, fly into it, or around it, it's hard to beat it.
Students!
Check out our Puzzlers. If you have a solution to one of these, send it
along to us. We will publish the solutions
on this page along with the author's name. The ratings vary from 1 to
10.
Here,
1 is challenging for High School students, and 10 is challenging for Ph.D.s

Individual members of the Library are invited to talk to a teacher
at the Library about questions they have concerning topics that arise
in any of the Microworlds or WorkBooks here. Just click here
and send your message. We will try to respond promptly.
Library Puzzler #1 (rated 2)
Do you see the Golden Ratio?
Did
you ever wonder what Calculus is really about? Where did it come from,
and why? It is not likely that you will learn the answers to those questions
in a textbook. If you are curious and want to know, then our free
500 page book, Calculus in Action
may be for you.
The
book, which consists of 49 lectures and 43 Interactive Explorations, is
presented in 10 Mathwright Microworlds. All of the text (500 printable
pages) is contained within the Microworlds. The hypertext version is free
for everyone, and the PDF version as well as the interactive Microworlds
are available only to Library members. And our book is not for the faint
of heart. It is not a textbook, and you will find it far more challenging
and, we hope, more interesting than any hardcopy text can be. No hardcopy
text
will let you test Newton's
laws by docking a space shuttle with a satellite in a 3 dimensional simulation,
show you the retrograde motion of Mars in the night sky, or let you test
each of Kepler's Laws of Planetary Motion as you follow Newton's deduction
of them using his Calculus.
This
book is designed to illuminate, and to give readers the chance to explore
in some depth, the basic ideas of Calculus within the context of its first
triumphal scientific success: Isaac Newton's deduction of Kepler's three
laws of planetary motion from his single hypothesis of Universal Gravitation.
Our
book differs from a Calculus textbook in several ways. While it assumes
a basic understanding of Geometry and Algebra, it is designed around the
theme of Gravitation, rather than any particular syllabus.
It is an Interactive Story that invites you to learn how
Calculus came to be.
Looking
for something specific? Check out the Gallery of Workbooks and Microworlds
in the Library Stacks.
There
are 28 rooms that organize our 250 books by topic and grade, ranging from
High School through Graduate level mathematics and science.
Choose
a room, and the books in that room will be listed with numbers of first-time
visits since January 2002. Then, click on a link to go to a title page
and read more about the book. The Microworlds are available to members
online in their browsers, and you can add them to your permanent collection
on your computer if you wish.

The
best way to get started reading Microworlds online in your browser is
to download a Free MathwrightWeb (or MathwrightNET) Player, and
to join the Library.
The
best way to get started reading Microworlds offline is to download a
Free Mathwright32 (or Mathwright32 NET) Player, and to join the
Library.
If
you prefer to see how things work before joining, then download a free
Player (we recommend Mathwright32 Reader
for offline viewing), and take a look at the Free Microworld Introduction
to Mathwright32 Microworlds in the Visualization Studio of
the MATH Cafe.
If you can fill a rectangle with squares, can you then fill it with squares of equal size?
