Gosper's Verstion of Stirling's Formula
Date: 05/30/2002 at 07:01:20
From: Amy Choi
Subject: Stirling's formula
I am doing a project on Stirling's formula, and I found that
there is a better approximation to n! which was noted by Gosper.
I would like to know a proof of the approximation which is

Small note on Quaternion distance metrics
There’s multiple ways to measure distances between unit quaternions (a popular rotation representation in 3D). What’s interesting is that the popular choices are essentially all equivalent.
Polar form
A standard way to build quaternions is using the polar (axis-angle) form

Non-Isomorphic Graphs with Cospectral Symmetric Powers
The symmetric $m$-th power of a graph is the graph whose vertices are $m$-subsets of vertices and in which two $m$-subsets are adjacent if and only if their symmetric difference is an edge of the

Cylinders and Elephants
Date: 05/30/97 at 00:47:44
From: philip brand
Subject: Volume and shapes of containers
Why are cans always manufactured as cylinders? I think it has
something to do with the amount of volume it can hold.
Are the volume of an animal and the surface area of its feet related?
