Sally Simplewit likes to make people guess the month and day of her birthday by asking only questions that can be answered "yes" or "no," such as "Are you a Sagittarius?" or "Were you born in the winter?" Sally's friend Samantha took 12 questions to guess her birthday, while Frank took 13 and Mortimer needed only 10.
Today's challenge: Can you do better than Samantha, Frank, and Mortimer?

Solution to yesterday's challenge



7 March 2004: Platonic Realms is pleased to announce that we have now made select resources available for download, including The Game of Hex, our humor collection Nowhere Dense, and Mathmo Downloadable Graph Paper. Each is available for a nominal download fee, in association with Amazon.com. Check out all our offerings at the Downloadables Page.

2 February 2004: Congratulations to our principle sponsor, Design Science Inc., on the success of MathType 5 for Windows and Macintosh, and on their outstanding products WebEQ and MathPlayer. MathType is a full-blooded equation editor that lets you create mathematical notation for word processing, Web pages, desktop publishing, presentations, and for TeX, LaTeX, and MathML documents. We at Platonic Realms are very impressed with the new features, especially the outstanding translators for TeX and MathML, and the full support given to preparing display equations for HTML. In fact, MathType 5 for Windows enables you to save an entire Word document as a Web page, with equations that print and display beautifully. By contrast, WebEQ is a complete development environment for putting interactive math on the web, including editing and publishing tools and a Java library for creating point-and-click, interactive math applications within your very own web pages. Finally, the MathPlayer plug-in allows browsers to render MathML encoded equations and notation.
      A SPECIAL NOTE: Design Science Inc., the makers of MathType, have been a supporter of Platonic Realms for most of the seven years we have been online – please show your support for Platonic Realms by visiting their site to learn more.
