December 13, 1900
I have not written in a long while, due to the fact that my last year has been very full. Firstly, I finally finished my formal list of geometric axioms. I became very frustrated with the mathematic community accepting something as vague as Euclid’s geometric axioms. He made too many assumptions and provided concepts with no formal definition! So I set out to fix the ambiguity and completely reinvent concepts which haven’t been touched in over two centuries! I started by specifying the three terms I would use, along with three concepts.
Terms:
- Point
- Line
- Plane
- Congruence - “Two binary relations, one linking line segments, and one linking angles, each denoted by an infix ≅ ”
- Betweenness - a ternary relation linking points
- Containment - three binary relations, one linking points and straight lines, one linking points and planes, and one linking straight lines and planes
Now I’m late for a meeting with a colleague of mine. We will be discussing my favorite of my twenty-three problems: the first. I hope this conversation will be both interesting and mentally stimulating!

David,
ReplyDeleteI was delighted to read your letter. First off, it is fantastic that you are furthering your understanding of Euclid's axioms. They have always been a little vague to me as well. I also understand the need to prepare for the future of mathematics. In my book, “Liber Abaci”, I have included many problems that I am sure will be discussed for years to come. The International Congress of Mathematics is lovely, and I’m sure you were treated well. I love the way you named your twenty-three problems, the “century problems”, though I am still disappointed the twenty-fourth did not make the cut. I am wondering if it is possible for you to send me the first of your twenty-four problems? I am also confused as to what field of mathematics you are speaking about in problems eleven and sixteen?
Sincerely,
Fibonacci
What a busy year indeed! I am so intrigued by your list of geometric axioms and love that you are specifying the details the Euclid didn't. It is very clear to me that you will have a major impact on the world of mathematics. Although I may not understand all of your rules, due to my lack of interest in the subject of math as a child, I can see how influential these problems will be. Like yourself, I have created my own notebook where I have included many geometric intricacies that relate to my art. I wonder if some of our work relates to each other? The conference in Paris that you attended, sounds wonderful. I am glad that I have a fellow colleague like you, who is dedicated to traveling the world to show off their work, just as I do. Finally, I am wondering what your twenty fourth problem consisted of, because the mystery behind it intrigues me greatly? It was quite lovely to read your journal entry.
