This may possibly be the strangest "poem" that Eskimo has ever received (and she thinks a few important mathematical symbols have been lost in translation). Eskimo begs to differ with strict grammarians who say that the word, "unique," cannot be modified. Eskimo thinks that there are some very unique individuals out there, and The Doctor is one of them. Eskimo first encountered The Doctor whilst standing outside of the Capitol Garage. She did not know him, and yet he approached her and asked if he could take some photos of her from behind. Now Eskimo does admit that she has very nice shoulderblades, but she did as she usually does when approached by strange photographers, and said, "You've got to be kidding, right?" and then she ran away. Eskimo next encountered The Doctor outside The Himovitz whereupon he proceeded to tell her without knowing her that he had just returned from New York and was glad to be back in Sactown where there were no pesky distractions and he could actually get some work done. Eskimo knows a genius when she encounters one (because she is one), and she also knows spectacular computer graphics when she sees them. Please check out The Doctor's web page at www.robotrepair.net. Then Eskimo wants you to contemplate the simplicity and harmony of poetry at rest.

Simple Harmonic Motion Consider a mass hung from a spring. If it stays still, it is in the equilibrium position. Lift the mass, or pull it down, and let it go. Then the mass bounces up and down. This is harmonic motion. We consider the simplest case, no friction or resistance. This is ‘simple’ harmonic motion. The energy is conserved and not dissipated. It would theoretically wiggle forever. Let ‘x’ be the displacement from equilibrium and ‘a’ represent the acceleration. Hooke’s law states that the force of a spring is proportional to the displacement from the equilibrium, i.e. F = kx. The spring constant ‘k’ has units of newtons per meter. The mass supplies an equal and opposing force to the spring’s push and pulls through newton’s second law, F = ma. Equating these leads to an equation of motion: m a + k x = 0 The sum of the forces on the mass is zero. To draw this, on the right side column, we use ‘ |--/ / / /----o ’ as the equilibrium position. This takes place at ‘time’ numbers 2 and 6. (We take "up" as increasing x here.) While the drawing in the right column is constrained by the font and its spacing, a sine or cosine wave is clearly seen running down the page – scrolling enhances the effect. Here is a table of minima and maximums of position, velocity, acceleration and the kinetic and potential energies. The checker board table represents the swashing back and forth of the wave. time x v a KE PE ________________________ 0 min 0 max 0 max 2 0 max 0 max 0 4 max 0 min 0 max 6 0 min 0 max 0 The wave length is 8, a zero at the eight’s time position indicates this. This length (or the frequency) depends upon the mass and spring. Solving the above equation we get: a = (-k/m) x. Acceleration is the second derivative of position, i.e. a = d2x/dt2. Let x = ewt. Now d(ewt)/dt = wewt. So the second derivative pulls out a square term, hence w2 = -k/m. Thus the solution is of the form: x = ei÷(k/m)t = cos(wt) + i sin(wt)
