• Algebra
• Geometry
• Trigonometry
• Calculusetc..
Rather, it is
• Play
• Tool
• Design
Talk explores
• Play– Magic– Puzzle– Game
• Tool – Tools for thinking– Tools for solving (How?)– Tools for understanding (Why?)
• Design– Science– Mathematics– Engineering

Spirit of Inquiry
Galileo Galilee
(Natural) Philosophy is written in this grand book — I mean the universe — which stands continually open to our gaze, but it cannot be understood unless one first learns to comprehend the language in which it is written.
It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures, without which it is humanly impossible to understand a single word of it.
