John Hunton: 5 and Penrose Tiling
John Hunton |
- We didn't see it because we didn't look for it.
- One of the ways in which, one of the most common ways in which patterns like this are found are by taking regular pattern, but in a much higher dimensional space, and then cutting through that space, at an irrational angle. And the irrationality of the way you've cut it will mean that you'll never get complete repetition.
