And gazed into the Sun,
You quoted Shakespeare, in my ear,
And changed the station, some,
And when we got there, to the park,
We laid down in the grass,
I rubbed your shoulders, soothed your back,
And you dozed off to sleep.
I watched you breathing to the beat
Of birds across the way,
But I wish I would have asked you if --
We learned about pressure today.
If by "learned" you mean reviewed from Nettles' class. I wish I could have skipped to 102.
By the way, assuming a theoretical compound Rhettium which is free from the effects of gravity (or, in Physical Science class, occasionally experiences a negative effect), you could experience similar pressure effects as you do in that UFO if you're floating in a Rhettium cloud 20 km away from the center of a black hole with mass 6.734 x 1024 kg (and thus event horizon radius of 10 km) with an escape velocity of exactly c.
Cooper Library (Clemson's main library) had a gigantic book sale this morning with incredible prices. All hardbacks were $2, all CD's were $2, all paperbacks were $0.50, all magazines were $0.10, and I can't remember the rest but I do know that they were all $2.00 or less.
So I spent $23 or so.
Here's what I got.
Book #1: Encounters: an Introduction to Philosophy
By beatings, of course, I mean hits. And by hits, of course, I mean pageloads.
So two weekends ago when I visited Charleston, by 4th grade teacher and long friend Mrs. Fisher sent me an off-to-college card with a Best Buy gift card inside. So Saturday night, Anastasia and I went on a shopping spree, and I bought - among other things - a Darren Aronofsky Collection with two movies: Requiem for a Dream (the movie which prompted me to buy this collection) and π. I had seen Requiem for a Dream before; it's a little disturbing, but it's a great movie. I'm sure that if we showed it in middle school, teenage drug use would decline.
But I had never seen π before, and the low price of the collection prompted me to buy the set. Last night, I watched it with Karen and Sammy. It was... okay. I loved the concept; a mathematician obsessed with finding order in chaos, and convinced that the entire universe and everything in it can be perfectly described with mathematics. Thus, he tackles one of the most chaotic systems in history: the stock market.
Already slight off his knocker, his attempts at ordering the stock market - and, later on, using similar patterns to find the true name of God - are unsuccessful, although he does come very close (there are hints that he actually does understand the patterns, but, even if this were so, he is unable to apply them to any real problems). Between his existing mental problems, the pressure of sorting through the disorder, and the consistent attacks by organizations - both religious and corporate - leeching off of his talents for their own good eventually do him in.
So it was a pretty good movie... until I heard something wrong. As soon as I heard it, the rest of the movie lost its reality and truth that normally makes movies really hit hard with me. The issue was when he referred to the golden ratio (which, for the curious, is exactly equal to (1+sqrt(5))/2) as theta. I've actually done lots of reading on the golden ratio and on sacred geometry in general, and I have never, ever seen it expressed as theta. Traditionally, it is represented by the greek letter phi.
Instantly, I knew something was up.
He also used the Fibonacci sequence in the movie, and claimed that 233/144 approaches phi (which he again expressed as theta). While it's true that the limit as t→∞ of F(t)/F(t+1) does approach the golden ratio, 233/144 doesn't approach anything. It's just 1.6180555555..., which is a static number very close to, but certainly not equal to, phi. And it doesn't approach anything; it just is.
Anyway, I'm sure there were plenty more math errors. One thing that particularly bothered me was that this brilliant number theorist who nearly predicts the future of the stock market was, at one point, pondering A=πr^2 and C=πd on the train, as if they held mythical truth. As a matter of fact, wtf is this movie even called π? It had nothing to do with circles! He did find some golden spirals, but then the movie should be called Φ, not π. I dunno. The title confused me by the end. Those basic area and circumference equations were the only real reference to π, except of its basic nature as an irrational number.
Anyway, if you watch it, let me know what you think! Despite my mathematical distress, it was, overall, a pretty okay movie worth watching once or twice just so you can say you did. And, in a brilliant stroke of coolness, it's in black and white!
A tutorial for those new to Perl but not to Programming: Part 0
#!/usr/bin/perluse warnings;use strict;print "Hello, world!";
There's our familiar Hello, world! program. The first three lines are unnecessary, generally. You could write the program as simply print "Hello, world!";, execute perl
$variable = 5;$variable = "Hello, Janet!";$variable = \$referenced_var$variable = \&referenced_subroutie$variable = -234.3$variable = 0x0000003f;$variable = "Some other data type!";print $variable; # prints out "Some other data type!"... and yes, this is a valid program.# By the way, this is a comment!
