Hyperbolic Space - Mathematical Art
I mentioned a circular disk pattern that appeared in the film "Dimensions：A walk through mathematics". Actually this pattern is as fascinating as 4D space - Hperbolic tessellation in hyperbolic space.
Build Digital Circuits with Hutton32 (II): Logic Components
The previous article introduced AND, OR, and NOT gates in Hutton32. Now let's use their combinations to do some interesting things. (Like a perfect square calculator!)
Build Digital Circuits with Hutton32 (I): Logic Gates
Recently I saw someone use redstone circuits in Minecraft to create a calculator, it seems to be able to calculate floating-point numbers and trigonometric functions. I don't know much about redstone,
Electron-Deficient Planet vs Electron-Rich Planet
In the direction of Ursa Major, at the edge of the M82 Cigar Galaxy dozens of light-years from Earth, there exists a lonely star system. Apart from the star at its center, this system contains two p
Inverse Earth
This is a special world. In this world, you still have blue sky overhead and solid ground beneath your feet, seemingly no different—yet this world is completely different. In this world, even vacuum h
4D Space (VIII): Visiting a 4D Country
Now imagine one day you are invited to visit a 4D country and learn about their culture and science and technology. What would that be? In the vast 4D universe, galaxies are scattered sporadically. Th
