USS Skipjack, Miranda-class: The Skipjack was an American submarine during WW2.
USS Hornet, Excalibur-class: The Hornet was an American carrier during WW2 (sensing a pattern?)
USS Indianapolis, Dakota-class: I grew up in Indianapolis, *and* the Indy was a heavy cruiser during WW2 that delivered the components of the atomic bomb. Before being sunk and eaten by sharks.
USS Atlas, Celestial-class: The Celestial-class is a *really big ship*. And before the latest update, it moved like it was carrying the world on its saucer.
All of my ships were named after famous mathematicians, and my NCC registries coincided.
Just a few examples:
USS Euler, NCC-271828-E (Euler came up with the constant "e" which equals 2.71828...)
USS Pythagoras, NCC-235711 (Pythagoras was the first to distinguish between prime and composite numbers, so the registry is every prime number that can fit into 6 spaces: 2, 3, 5, 7, 11)
USS Fibonacci NCC-112358 (Fibonacci series: 0, 1, 1, 2, 3, 5, 8, ... where each number is the sum of the two previous numbers; found a lot in nature)
USS Descartes NCC-162536 (Among other things, Descartes "invented" the format to use superscripts to show powers/exponents, so the register is a group of three squares: 4², 5², and 6²)
That's all for now. My next ship will be the USS Archimedes, registry NCC-314159 (any guesses?)
