At breakfast time I was sitting by the house at Vanavara Trading Post [65 kilometres/40 miles south of the explosion], facing north. [..] I suddenly saw that directly to the north, over Onkoul's Tunguska Road, the sky split in two and fire appeared high and wide over the forest [as Semenov showed, about 50 degrees up—expedition note]. The split in the sky grew larger, and the entire northern side was covered with fire. At that moment I became so hot that I couldn't bear it, as if my shirt was on fire; from the northern side, where the fire was, came strong heat. I wanted to tear off my shirt and throw it down, but then the sky shut closed, and a strong thump sounded, and I was thrown a few metres. I lost my senses for a moment, but then my wife ran out and led me to the house. After that such noise came, as if rocks were falling or cannons were firing, the earth shook, and when I was on the ground, I pressed my head down, fearing rocks would smash it. When the sky opened up, hot wind raced between the houses, like from cannons, which left traces in the ground like pathways, and it damaged some crops. Later we saw that many windows were shattered, and in the barn a part of the iron lock snapped.
This is mostly because adding emotions to claims means that we are storing two separate things - the claim and the emotion. For memory, this adds some complexity to the storage of this information in your brain, making a bigger memory network that is more likely to be recalled later.
We also know that emotions, particularly fear, can have a profound impact on decision making. When we are afraid, or asked to focus on arguments based on fear, we generally shift into something called peripheral processing.
Peripheral processing happens when we form an opinion based on cues that surround an argument, at its periphery. This is the information, like emotion, or the attractiveness of a speaker, that is related to how a message is presented rather than the message itself.
Ken begins the Xerox Alto restoration - good stuff for those into historical hardware. The Alto is one of those very significant machines - first built with a GUI and mouse and introduced the laser printer and ethernet - all a decade before the first Macintosh.
