DIY Core Rope Memory Z80 Demonstrator Generating A Fibonacci Sequence

We’ve seen a few retro products using core rope memory, such as telephone autodiallers. Obviously, we’ve covered the Apollo program computers, but we don’t think we’ve seen …

Math You Can Wear: Fibonacci Spiral LED Badge

Fibonacci numbers are seen in the natural structures of various plants, such as the florets in sunflower heads, areoles on cacti stems, and scales in pine cones. [HackerBox] has developed a Fibonac…

Today's #flower in the #garden is a star of Behtlehem. At least it looks like one of the many #species of #plants that go by that common name and I'm not a botanist and won't try to be more specific. It has six #petals which struck me as odd (no, not odd, you know what I mean). The number of petals is often a number from the #FibonacciSequence and so what might happen here during development is that each of the three petals split into two. I'm just speculating and I'm sure there are many more knowledgeable people who could give the right answer.

This second image is a cropped version of the one above. You can see the #stamens covered in yellow #pollen well. Instead of putting the centre of the flower in the centre of the image, I've used the #RuleOfThirds to try to make it a bit more interesting, which has the added benefit of being able to fit an entire petal into the frame.
