Yashoku didn’t show anything out of the ordinary when he shook his hand.  Some of the powder was transferred to him.  Its effect wasn’t great but it did make the people who touch it and inhale the dust a little sleepy.  Because he had been around it so often, Yashoku had built a tolerance to it.  “It is nice to meet you CJ.”  He smiled when CJ asked him about physics.  He just hoped that CJ was easy to bore.  “Well, we study how things happen.  Like when you drop something we figure out why it fell.  You figure out how fast it was going one second after the drop, how fast it was going two seconds after the drop, and so on and so forth.  It is really math heavy and there is a fair amount of high level math.  Calculus is used a lot because you have to use integration and differentiation a lot to find things like areas under curves or the length of a curved line and things like that.  You also deal with light and how fast it was going and proving that how fast it was going was really how fast it was going.  Figuring out how heat affects things too is done some, like figuring out how many millimeters something might expand if the temperature increases by 5 degrees Celsius.  Also the forces from bending and gravity are also used.  Like let’s say that a 10 kilogram brick was dropped onto a thin steel beam from a height of 5 decameters.  If the steel bent 20 degrees at the lowest point when the brick made contact with it I could figure out the spring constant of the steel.  Stuff like that.”  As he talked he left no room for CJ to interrupt him.  Also, his voice was almost completely mono tone and he didn’t make any movements when he spoke.  He tried to make it as boring as he could and hopped that he could help the powder make him tired.
