About this entry
A retired engineer keeps recording radio signals nobody else hears. The editors’ note placed it here on the basis of three criteria: durability across re-reads (or re-watches, or re-plays), influence on the entries that came after it, and the degree to which it could only have been made by the person — or team — who made it.
In the comparative table maintained by the Film desk, Ferrograph sits within a band of 25 – 31 that contains some of the most contested swaps of the year. Editors vote with arguments; a swap requires three editors and one written defense.
From Wikipedia
Ferrography is a method of oil analysis used to inspect the severity and mechanisms of wear in machinery. This is achieved by separating ferrous debris from lubricating oil by use of a magnetic field with an instrument called a ferrograph, the result is then examined with microscopy. A trained analyst can then diagnose faults or predict failures.
