- Strange Attractors | Shashank Tomar (blog.shashanktomar.com)
A few months back, while playing around with Three.js, I came across something that completely derailed my plans. Strange attractors - fancy math that creates beautiful patterns. At first I thought I’d just render one and move on, but then soon I realized that this is too much fun. When complexity emerges from three simple equations, when you see something chaotic emerge into beautiful, it’s hard not to waste some time. I’ve spent countless hours, maybe more than I’d care to admit, watching these patterns form. I realized there’s something deeply satisfying about seeing order emerge from randomness. Let me show you what kept me hooked.
- Zinc (Wikipedia)
Zinc is a chemical element with the symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth’s crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).
