Votes:0 The Sierpinski triangle. (Next Section) Chaos in the Classroom (Cover Page) Chaos in the Classroom (Previous Section) BU Math Home Page The Chaos Game One of the most interesting fractals arises from what Michael Barnsley
has dubbed ``The Chaos Game'' [Barnsley]. The chaos game is played as
follows. First pick three points at the vertices of a triangle (any
triangle works---right, equilateral, isosceles, whatever). Color one
of the vertices red, the second blue, and the third green. Next, take a die and color two of the faces red, two blue, and two
green. Now start with any point in
the triangle. This point is the seed for the game. (Actually,
the seed can be anywhere in the plane, even miles away from the
triangle.) Then roll the die. Depending on what color comes up, move the seed half t Read More Go to Site

Votes:0 Combinatorial Game Theory Combinatorial Game Theory studies strategies and mathematics of
two-player games of perfect knowledge such as chess or go (but
often either concentrating instead on simpler games such as nim, or
solving endgames and other special cases). An important distinction
between this subject and
classical game theory (a branch of economics) is that game
players are assumed to move in sequence rather than simultanously,
so there is no point in randomization or other information-hiding
strategies. The bible of combinatorial game theory is Winning Ways for
your Mathematical Plays , by E. R.
Berlekamp , J. H. Conway, and
R. K. Guy; the mathematical foundations of the field are provided
by Conway's earlier book On Numbers and Games . Many papers

Votes:0 CopyCat CopyCat is a captivating new 3D game designed and developed by Jim Morey . The game revolves around replicating a picture created by several patterned faces of a solid object (like a cube). This may sound easy to some, but it can turn out to be quite tricky. So to do well at the game, the player must first become familiar with the object. CopyCat is rich with variety. There are many different pictures that can be created with the patterned faces of just one object...and there are many different objects that can be used. For a more subtle variation, the way the player manipulates the object can also be changed. All of these possibilities unite to make CopyCat the most challenging game your mouse will ever experience. If you are scratching your head, take a look at the game . Otherwi Read More Go to Site

Votes:0 Get as much money in your piggy bank as possible, by figuring out the correct change. Figure out how many of each bill or coin that you expect to get back when you pay for something. For example, if something costs $3.75 and you pay with a five dollar bill, you would expect back one quarter and one dollar bill. If you get the answer correct, the amount of change is added to your piggy bank. If you get the answer wrong, the correct amount of change is subtracted from your piggy bank. The more money you get in your piggy bank, the harder the questions will get.

Votes:0 Ivars Peterson's MathTrek May 19, 1997 Around the Dartboard You may have noticed that the numbers on a standard dartboard have the following order, going clockwise starting at the top: 20, 1, 18, 4, 13, 6, 10, 15, 2, 17, 3, 19, 7, 16, 8, 11, 14, 9, 12, and 5. Why this particular order? A possible criterion for designing a dartboard is to penalize poor shots as much as possible. That can be done, for example, by maximizing the sum of the absolute value of the difference between adjacent numbers. The larger this sum, the more a poor shot is penalized. To achieve this maximum, the numbers 11 to 20 should interlace 1 to 10. In this case, the differences between adjacent numbers total 200. A standard board with 20 sectors has a total of 19!

Votes:0 The 3x+1 problem and its generalizations*** Jeff Lagarias AT&T Bell Laboratories Murray Hill, New Jersey Math activated text Other available formats Related links Author biography Abstract: (taken from the Introduction) The 3x+1 problem, also known as the Collatz problem, the Syracuse problem, Kakutani's problem,
Hasse's algorithm , and Ulam's problem ,
concerns the behavior of the iterates of the function which takes odd
integers n to 3n+1 and even integers n to n/2 .
The 3x+1 Conjecture asserts that, starting from any positive integer n , repeated iteration of this function eventually produces the
value 1 . The 3x+1 Conjecture is simple to state and apparently intractably hard to solve.
It shares these properties with other iteration problems, for example
that of aliquot sequences and wi Read More Go to Site
