This is a bit of a bizzare question, but I'm going to ask it anyway.
If $X={\rm Spec}R$ is an affine variety, and $\mathfrak{m}$ a closed point, then the localization $R\to R_{\mathfrak{m}}$ gives a morphism
$f:{\rm Spec}R_{\mathfrak{m}}\to{\rm Spec}R$,

Informal challenge: You are given a discrete distribution with n possible outputs (and you know the probability p[i] of each output), and you want to sample from the distribution. You can use a

Calculating gear inch for 406 wheel
When I enter the following to the Sheldon gear calculator:
Tire: "20 X 1.75 / 44-406 / BMX tire"
Chainring: 52T
Cassete: 11T
I get 88.3 gear inches.
