181. Wear of a Stainless Steel Ferrule
... Each ferrule will be used to plug approximately 300 holes. We must be sure the ferrules will not wear excessively during use; 1 mil reduction in diameter of a ferrule is enough to reduce light throughput by approximately 1%. ... Stainless steel ferrules offer lower precision (which will lose us approximately 1/2 to 1% light compared to ceramic), but they are relatively inexpensive, readily available with the hole diameter we require, and immune to cracking. ... Hence the wear was not very deep. ...

Atomic priors One useful way of breaking down the complexity of a problem is to construct the ob ject as some number of a-priori-equivalent "atoms", which are scattered randomly over the domain of interest. ... As it happens, the number of attributes (dimensions) ascribed to an atom is often small, so the mere fact of using an atomic prior much reduces the difficulty: we seek to control only one or two atoms at a time, not the entire ob ject. ...
