  The International Mathematical Olympiad (IMO) 2001 
  competition was held July 1-14, 2001, in Washington, DC. 
  Over 80 countries participated this year, each sending up 
  to six students under the age of 20 who have had no 
  postsecondary-school education.

  This site records scores and supplies competitor information, 
  and includes a photo gallery and a summary of IMO Facts. 
  The 2001 competition problems are available on the Web at:

               http://imo.wolfram.com/problemset/

  The file may be downloaded in Mathematica notebook and PDF 
  formats. There is also a link to an archive of problems and 
  solutions beginning with the first IMO Olympiad in 1959, by 
  John Scholes:

  What would a billion (or a trillion) pennies look like? Find 
  out at the MegaPenny Project site, in pages listing data on 
  one to one quintillion pennies. All the pages have tables at 
  the bottom, and include:

    - the value of the pennies
    - the size of the pile
    - the weight of the pennies
    - the area of the pennies if laid flat

  All weights and measurements are U.S. standards, not metric. 
  Don't miss the special section, MegaMoo!
