Graham’s number – Author David Wells wrote “”If all the material in the universe was turned into pen and ink it would not be enough to write the number down.” So, yeah, using some unconventional notation, Graham’s number can be written, but in anything approximating normal notation: there are not enough atoms in the universe to denote it.
Fifth and sixth derivatives – The first and second derivatives (velocity and acceleration, respectively) are easy enough to grasp, but the third and fourth take a bit more thought. Change in position through time? Velocity. Change in velocity through time? Acceleration. Change in acceleration through time? Jerk. But, uh, the fifth and sixth derivatives? Crackle and pop, respectively.
That is all. I am going to see about having my mind vomited back up.
