THE JOY OF MATHEMATICS &
MORE JOY OF MATHEMATICS
by Theoni Pappas
Part of the joy of mathematics
is that it is everywherein soap bubbles, electricity, da Vinci's
masterpieces, even in an ocean wave. Written by the wellknown
mathematics teacher consultant, this two volume collection of
over 500 clearly illustrated mathematical ideas, concepts, puzzles,
and games shows where they turn up in the "real" world.
You'll find out what a googol is, visit hotel infinity, read
a thorny logic problem that was stumping them back in the 8th
century.
"Pappas
demystifies mathematics in a collection of miniature essays called
The Joy of Mathematics." The New York Times
"Approach goes far beyond the usual mechanical presentation,
linking math to vital, everyday life and adding cultural and
historical influences to connect math concepts to realistic challengesfun
rather than tedious." The Bookwatch
"The Joy of Mathematics presents the world of mathematics
to readers in a fresh, original way. For any reader, mathematician
or noteasily readable by allreadily usable for enrichment I highly
recommend it." The Mathematics Teacher
" designed to help the reader become aware of the inseparable
relationship of mathematics and the world by presenting glimpses
and images of mathematics in the many facets of our lives."
Science News
"Rarely does one come across books on mathematics with such
breadth, beauty, and insight. Pappas' books always contain fascinating
and valuable informationnot only for the curious students and
laypeoplebut also for the seasoned researcher." Clifford

THE MATHEMATICAL SCANDALS
by Theoni Pappas
In this highly readable volume of vignettes, coupled with factual
background, Pappas has assembled fascinating stories of intrigue
and the bizarre  in short, the human background of the history
of mathematics.
MATHEMATICAL SCANDALS delves behind the scenes and reveals real
people, whose rivalries, deceptions, and idiosyncrasies are at
odds with the mathematician's reputation for clear thinking and
scientific detachment.
"If you have a kid
over, say 16 years who thinks math is boring, this book is the
cure." Jaron
Lanier, Discover
Magazine
"These scandals
are not salacious tabloids; rather, they concern incidents and
controversies involving personalities from the history of mathematics.The
stories are informative, and the writing style is appealing."
The Mathematics
Teacher
"Pappas'
passion for math has produced many previous winning titles: this
presents a new vision for exploring math Even reluctant math
users will find the blend of intrigue and social history involving."
The Bookwatch
"MATHEMATICS
SCANDALS gives Pappas' devoted fans another dose of the inventiveness
and flair they have come to expect from her work." Publisher's Group West
"Many associate
mathematics with cold logic. To dispel the stereotype, the author
examines the human sides and foibles of renowned mathematicians." Douglas Borton, The Actuarial

in their works and how many writers draw upon the wealth of its
ideas. Experience all this in The Magic of Mathematics.
 "Thoughtprovoking
yet not overwhelming, this book makes the author's pleasure in
mathematics evident. "
Library Journal
 "witty and intriguing" Science News

 "Readers will relish
this book. The focus is to explain math in a lively, revealing
manner. It succeeds!" The
Bookwatch

 "Pappas writes at
a level that puts all her topics within reach of any mathematics
teacher and usually within reach of a generalist as well. In
spite of this, she does not skim over facts or misrepresent them.
If you haven't bought Pappas' first two books, then get them.
If you have them, buy this one as well." The Mathematics Teacher
Like Pappas'
The Joy of Mathematics, the illustrations, graphics
and photographs in The Magic of Mathematics make the book
a visual as well as an intellectual experience.

mathchallenges
by
Theoni Pappas & Dale Lindley
now available
at through iTunes or the Apple APP store
Kick start your brain with MATHCHALLENGES.
99 challenges that will exercise those gray cells. Whether it's
a computation problem, a thought challenge, problems involving
advanced equations or just challenges that use plain old
logic, you'll have to resort to mathematical thinking.
Remember mathematics is an active sport. A pencil, paper and
perhaps a calculator are your tools. The challenges cover a range
of math problems, which may both challenge and amuse you. Sometimes
math skills will help you solve them, other times you may rely
only on logic.
MATHCHALLENGES is designed
so that you can tackle only one mathematical challenge in a twentyfour
hour period. During that time, if you get stuck, you can ask
for a hint. Or, if you are frustrated, you can always look
at the solution, but you cannot go to the next challenge until
a day has passed. Why? Because for some challenges
our minds may need time to process the information and seek out
that 'aha' moment. Some math challenges need time to percolate
in our minds. So to remove the temptation of rushing to
know the answer, the 24 hour rule lets us mull over the problem,
and even, perhaps, come up with alternate ways to solve it.
A hint can be accessed for a challenge in case you need a boost,
and when you do check your answer, an indepth solution
is given which may afford new insights.
Problem solving fuels imagination
and creativity. These 99 challenges will stimulate your brain,
challenge your wits and increase your confidence. Solving or
understanding the solutions will both increase your confidence
and understanding of math, and with each solution you will experience
a sense of accomplishment. The challenges that you don't solve
will perhaps provide new insights on how to approach various
problems. By the end of these 99 challenges you will have enhanced
your mathematical tool kit.
