Hi

This is an informal personal talk about the influence of accessibility on a math research problem, and vice versa. The problem is to define something like Pascal's triangle, but with the rows summing to the Fibonacci numbers. Such I call a Fibonacci wedding cake, as it is an elaborate tower made out of multiple tiers.


Here's something that surprised me. Pascal's triangle can be presented in several ways. For a sighted person the usual way (using Markdown) is:

||||| 1 |
|||| 1 || 1 |
||| 1 || 2 || 1 |
|| 1 || 3 || 3 || 1 |
| 1 || 4 || 6 || 3 || 1 |

The surprise was the thought that for a blind person (again in Markdown) this left-aligned form might be much better.

| 1 |
| 1 | 1 |
| 1 | 2 | 1 |
| 1 | 3 | 3 | 1 |
| 1 | 4 | 6 | 4 | 1 |

I'd very much welcome any feedback on access to number triangles. Although the Fibonacci wedding cake is connected to some advanced topics, no special knowledge of pure math is required for this talk. Just an interest in learning about and discovering patterns.

with best regards

Jonathan
