Brandon Sanderson / Re: Warbreaker Error?

Something about Warbreaker has been bothering me, in the "It doesn't really matter, but I need to tell someone, otherwise I might explode" kind of way. This thread looks like a place where it might fit in, so I'll try here:

One mechanic in Warbreaker is how Breath transfer is all or nothing. The characters themselves make a large number of references to this throughout the book. However, there appears to be a work around, in that if a character puts some (not all) of their breaths into an object, then give away his or her breaths, the character can still reclaim the breath in the object. This allows them to give away a fraction of their total breath, rather than all of it. This does take place in the book, but the way the characters talk, it doesn't feel like they are aware of this possibility.

Alright... Let's turn on nerd mode here. Haven't had physics for a couple years now, but it seems like you could see this as conservation of momentum:

Taking some of the larger values for a .50 caliber round from http://en.wikipedia.org/wiki/.50_BMG, we can say the bullet has a mass of 0.052 kilograms and a speed of 928 meters per second, which gives us a momentum of 48.256 kg * m/s.  Transferring all that momentum to a 50 kg object (say, a person who weighs about 110 pounds), we get a speed of less than 1 m/s (or less than 2.25 miles per hour).

So I would say it is definitely possible to deflect bullets (even without pewter), as the above scenario was overestimated in basically every aspect, especially since deflecting the bullet doesn't take nearly as much effort as stopping the bullet.

The real question, as I think some people have alluded to, is whether a human would have the reflexes needed to direct their abilities towards stopping a fired bullet. It seems more likely that the bullet would never be fired then that it would be deflected after being fired.
