First order of business today was Algebra. I learned about the midpoint and distance formulas. So, the midpoint formula states that if a line segment has endpoints at (x1, y1) and (x2, y2) the midpoint of the segment has the coordinates ((x1 + x2) / 2), ((y1 + y2) / 2)

The distance formula states that the distance between two points is given by d = square root of (x2 – x1)^2 + (y2 – y1)^2


Next up, Economics. I learned about the transition to capitalism, the economic system in which private citizens own and use the factors of production. There are some problems towards moving towards capitalism, however. State owned factories need to be privatized, and part of that is the loss of political power. There are also some costs associated with capitalism for the unprepared. For example, during the great depression there was instability, unemployment, and social unrest. Luckily, there are policies to prevent those types of things from happening again, at least for the same reasons.


Lastly, Programming. Today I’m going to be covering something I probably should have covered earlier, master/slave communication. In simplest terms, it is when one device is given control of one or more other devices, in order to manage their actions and give them further communication. One of the advantages of it is that you could configure the main device to be as fast as possible, while configuring the others to do more.
