What dynamical system is this? Is it known? Has it been studied?
If someone offers you $1 today, $2 tomorrow, $3 the next day, and so on in perpetuity, watch out! They are trying to steal 1⁄12 of a dollar from you…
This is amazing.

Mathematics and Architecture
The link between math and architecture goes back to ancient times, when the two disciplines were virtually indistinguishable. Pyramids and temples were some of the earliest examples of mathematical principles at work. Today, math continues to feature prominently in building design. We’re not just talking about mere measurements — though elements like that are integral to architecture. Thanks to modern technology, architects can explore a variety of exciting design options based on complex mathematical languages, allowing them to build groundbreaking forms. Take a look at several structures past the break that were modelled after mathematics.
1. Mobius Strip Temple, China
2. Tetrahedral-Shaped Church, Colorado
3. Pentagonal, Phyllotactic Greenhouse and Education Center. The Eden Project, Cornwall
4. A Mathematically-Inclined Cucumber in the Sky, London
5. Experimental Math-Music Pavilion, 1958 World’s Fair
6. Modern Music-Math Home, Toronto
7. Solar Algorithm Wizardry, Barcelona
8. Cube Village, Holland
9. Magic Square Cathedral, Gaudi Cathederal, Barcelona
10. Fractal Gas Station Makeover, Los Angeles
How many of these have you been to?
(Personally, I’ve only seen the Gaudí Sagrada Família church, which isn’t a cathedral btw.)
My activity is “Space Invaders”.
