Bohr's theory that electrons existed in set orbits around the nucleus was the key to the periodic repetition of properties of the elements. The shells in which electrons orbit have different ...

These studies often combine techniques from complex analysis, algebraic geometry, and number theory to uncover deeper ... that eventually enters a periodic orbit under iteration of a function.

One of U-Turn Audio’s selling points is ease of setup. The Orbit Theory continues this tradition, arriving largely assembled, with the cartridge expertly pre-installed. After popping the platter ...
