Ever heard of the "Crack-Bang" method? Sound delay ("crack-bang"): The enemy's supersonic bullets produce a sonic boom, creating a "crack" sound as they pass by. If the enemy's bullet speed is known, their range can be estimated by measuring the delay between the bullet's passing and the sound of the rifle shot, then comparing it to a table of values.
I saw what's been going on. That motherf**ker needs to shut his mouth up. I've been in his sights for a while now, so has Claybourne, Flaming, and other people. It needs to stop. I'm done screwing around.
Math, as in algebra and geometry, made no sense to me and seemed pointless until I had a place to apply it, then everything fell into place. Also thinking back, I'm pretty sure my teachers were pretty shit at their jobs.
