DFA: A BLOG ABOUT LIFE ON THE BASEBALL MARGINS: June 17, 2008
DFA, chapter 30: Some Clicks from Ric
Working on the old Blog Monster while trying to win a backup catching job with the New York Yankees is exhausting. Somehow I don’t think that saying I need a couple days off to update my blog would go over well with Joe Girardi and Brian Cashman. So as promised, I’m turning today’s post over to a few of my loyal readers to feature their blogs.
Welcome to the first edition of “Clicks from Ric.” I hope you enjoy them as much as I would’ve (if I’d had the time).
Rutilus SOX Nacio
(by the Harvard University Classics Department)
Extolio David Oritz et laudatio Dice K. etiam maio Mike Lowell mei optimi aegrissima est, et putamus eam morituram esse Coco Crisp. Non compos mentis Don Zimmer. Greco god ambulo Kevin Youkilis Manny Ramirez non penetrabilis … E Manny being Manny, ut profuissem, et modo minimo Doug Mirabelli, familiae suae.
Rutilus Sox aboleo Yankees. Frendo Derek Jeter et Yankee Coliseum et feculentia, purgamentum.

Blind item: What all-time HR leader crippled an old lady by head-butting her with his giant skull in a PIggly Wiggly last week?
Blind item: What ex-Red Sox pitcher now on a New York team hurt his shoulder midget-bowling?

Answers: 1: D, 2: A, 3: I, 4: H, 5: F, 6: J, 7: E, 8: B, 9: C, 10: F.
Score: 0-3 correct: Dumbass. 4-7: You could spend a little more time on our Web site. 8-10: You are a mortician, and thus probably a fan of the Pittsburgh Pirates.

Given a scalar field j, the Laplace equation in Cartesian coordinates
(x + 1)2 = x2 + 2x + 1
This equation arises in many important physical applications, such as potential fields in gravitation and electro-statics, velocity potential fields in fluid dynamics, etc. Typically we are given a set of boundary conditions and we need to solve for the (unique) scalar field j that is a solution of the Laplace equation and that satisfies those boundary conditions. A solution of Laplace's equation is called a "harmonic function" (for reasons explained below).
Since the Laplace equation is linear, the sum of two or more individual solutions is also a solution. The usual approach to solving the Laplace equation is to seek a "separable" solution given by the product of independent function of > x, y, and z, as follows
(x + 1)2 = 2x2 + x + 1
Every solution can be expressed as a sum of (possibly infinitely
many) solutions of this form. Inserting this into the Laplace equation and evaluating the derivatives gives us (x+2y)3 = x-2
Dividing through by the product A(x)B(y)C(z), this can be written
in the form a+2=pi (x)(y)(z)
Since x, y, and z can be varied independently, this equation can be
identically satisfied only if each of the three terms is a constant,
and these three constants sum to zero. It will be convenient to
denote these constants by squared quantities, a2, b2, g2 respectively.
Thus we have three separate ordinary differential equations.
All of which proves that Reggie Abercrombie truly sucks.
