#1 It is really an extension of the noise cancellation technology in your speakerphone. Very interesting and clever.

#2 Vibration isolation is a small but significant subset of that universal definition of life itself:

Friction Management

#3 The Right Amount.

In the Right Place.

At the Right Time.

Why, if it wasn't for friction, we'd all fall down - and never get up again...

#4 I also like the chief engineer's saying from "The Sand Pebbles":

Maintain an even strain.

It refers to the optimal distribution of vibration and off-center torque in the driveshaft of a naval vessel. Some main bearings of the drive line are loosened and others tightened to achieve minimum vibration and noise.

#5 The Right Amount.

At the Right Time.

Makes Jack a happy camper. [big grin]

#8 The past methods described are pretty much pre-war or early WWII, which does not say a lot about the Navy. Shock and vibration noise are no jokes. Bismarks' hydrophones could 'hear' Hood and Price of Wales before they met in the Denmark Strait and both Prince of Wales and Repulse were sunk inpart due to their machinery being knocked off their mounts by shock waves of explosions and near misses.

Pretty painful movie in general. The entrenched racism and encouragement of "looksee" imitation, instead of actual teaching, like McQueen's character was doing. I strongly recommend reading the book. Just don't expect the usual Hollywood ending.
