On this day, I learned that Edward Scissorhands(movie and man) is so cool. I just want to cuddle him!

I learned that there are a nebula, Jupiter, Saturn, Uranus, and Neptune past Mars in Dolphin Olympics. Pretty cool!

I learned that the day before Easter is a HUGE shopping day. I guess this makes sense; everyone’s picking up last-minute ingredients for big family dinners, easter candy, church dresses. It was kinda shocking though.

I learned that there is a pretty flower garden in the Walton Arts Center’s little ampitheater. It looks like it would be a cute place for a wedding! Has a little arch and everything.

I also learned that THERE ARE MORE ACORNA BOOKS OMG. I only finished the second one out of necessity. I started the first one in the hopes that maybe not starting in the middle of a series would make it make more sense, but no, I didn’t even finish that one. WHY UNICORN GIRL, WHY?

I learned about gender roles indoctrination of the 70s. JUST LIKE MOMMY JUST LIKE DADDY A TWO-IN-ONE WONDER BOOK. Makes me think of the stories Mom has told me about her school dresscode and fighting with grandpa over what she wore. (Mom, tell me more of these)

I also learned that Wal*Mart does not carry Jones Soda or Pepsi Natural . So much for my cane sugar fix.
However, Wally did have shrimp + lime ramen, and I learned that it is pretty dang good. Will buy again.

On this day, I learned that you can do better in dolphin olympics if you speed up by going at very flat angles instead of straight up; it doesn’t take as long to come back down then! (This is my quest to make it to the Restaurant in said game)

I learned that my thermo notes from wednesday are MIA :x And that you do an enthalpy equation at the feed water heater in an open feedwater heater cycle to find the mass flow through the pumps.
A feedwater heater cycle has a boiler, turbine, and two pumps. The first pump raises the pressure on the water, the boiler makes it hot, the turbine converts the high pressure hot gas into work. The second pump takes out some water out of the turbine before it cools down, and uses that to reduce work done by the boiler to reheat the rest of the water. Somehow it helps!

I learned that Stu and I aren’t the only ones who advance people’s laundry through the wash-dry cycle instead of just piling them up wet on the counter! That was a welcome surprise. I put my clothes in around 4 and pulled them out at 6 without having touched them.

I learned that UA jazz bands are wonderful to watch. Fluglehorns are so erotic!

I learned that the Sisters of Perpetual Indulgence are a San Francisco based order of LGBT activists. I would love to see them in a parade or festival there sometime.

On this day, I learned that using XL Thermal Props for thermo homework is FUN. Basically, Thermal Props is an excel plug-in that has a database of all the thermal properties of several different substances, and thanks to some basic tenets of material behavior, if you have two properties, you get the third. However, if you’re working from a book with charts, this is toilsome, since you can’t have every single temperature and pressure, and if you’re working from another property, you have to interpolate even more, because those don’t have their own pages. So Thermal Props is very convenient and we can’t use it on the test :[

I learned what it’s like to be a personal assistant to a famous author, as well as what not to mail them. (the assistant and the author)

I learned that a poem from my childhood was written by none other than T. S. Eliot (it’s impressive how famous names slip past you when you’re 8)

I learned about My Brute, which is a site where you make disposable flash entities to fight to the death :D I also learned that it is very hard to crack passwords, as I found out when I realized I had typoed my favorite password on the above site. Grrr.

On this day, I learned what you use eigenvalues for!
For a homogeneous ODE X’ = AX:

A X
[1 0 ][ a ]
[1 2 ][ b ]

Since this is a simple homogeneous example, we know that AX needs to equal the zero vector. We will subtract lambda (y for now) times the identity matrix for a 2×2 from A, i.e. A – yI and take the determinant:

A X
|1-y 0 |[ a ]
|1 2-y |[ b ]

Det(A-yI): (1-y)(2-y)-(1)(0) = (1-y)*(2-y). The solutions to this are y=1, y=2, our eigenvalues.

Now solve (A-yI)(X)=(0) for the vector X (the eigenvectors) for both eigenvalues. Write the system of equations this gives:
(1-1)(a) + 0(b) = 0
(1)(a) + (2-1)(b) = 0 => a = -b
Now, you get to pick any number in the world that isn’t weird or zero for a, then choose a b according to that pattern, maybe a=1, b = -1. Thus, your first eigenvector could be

X
[ 1 ]
[ -1 ]

Then find the second one with y = 2. Now, your solutions for the DE are
X = c1v1e-y1t + c2v2e-y2t

Fun inorite?

I also learned that mother cats are SO LOVING. Seriously, you can’t make up this kind of cute.

I learned that accountants like filing, working too hard, and arcane symbology.

I learned that before there was Photoshop, there was the Evening Graphic, which featured “composographs”.

On this day, I learned that I totally did not study enough for that Discrete test. Didn’t even have enough time to finish it ._.

I learned that phenylketanurics cannot process amino acids like phenylalanine in aspartame. So basically they have to avoid proteins, which is crazy to imagine for myself.

I learned not only that Dubai is a city built in the desert to be an oasis that entertains the world jetsetters and enriches the local upper class, but it seems to have destroyed the lives of many poor foreigners, including Americans who went broke.

I learned that some scenes in Disney movies aren’t as unique as they’d like for you to believe xDD

I learned that one gentleman (whose site seems to have been removed), when presented with a bill for $18000 worth of clip art, roused the twitter community by saying that he was being charged for his own work which was being ripped off by other people, but some people think he’s not telling the whole truth.

I also learned that a man in Quebec has been sued by his own daughter’s lawyers, whom she met during her parents’ divorce proceedings, and proceeded to contact when her dad tried to overrule her mother’s decisions.

I learned that AutoDesk is considering coming out with a mac version. This is so exciting! :D

I learned about an 8-bit waterslide.

I also learned that tarantulas totally have the ability to throw hairs in defense. Definitely using this as a plot device in my short story.

On this day, I learned that you can get jewelry made in the shape of your scars. Too bad I don’t really wear a lot of jewelry or have interesting shaped scars.

I learned that if you have a lump appear on your wrist, it’s probably a ganglion cyst. These are just fluif-filled sacs, but they look weird.

I learned that the more caffeine you drink, the worse your withdrawals!

I also learned that there’s a little Japanese robot (what else is new?) that is programmed to learn like a little baby :o

On this day, I learned that W = mRTln(P1/P2). That is, work is equal to mass times gas constant times temperature times the natural log of the change in pressure. At least this is probably true for ideal gases or something.

I learned that a stirling engine has two isothermal processes and two isovolumetric (or as my professor would say at a cocktail party, Isochoric) processes. (Fun fact, NASA is considering using the stirling process for Venus probes).

I learned that Old Navy totally has clothes that are my style, if not what I’d like to pay, and stu too. We want to both go back when we have money. Or he does. And I do too :D

I also learned that more people are close to going postal than you might think. And some are ready to apologize for their atrocities.

I learned that viruses could power cars!, you can draw music, and that polyvore allows you to sort through products (clothes) based on colors :D It’s really fun to browse. I found a $1400 tank top though :X It was so pretty.

I learned that a former classmate of mine may have been arrested for stealing $2000 worth of merchandise by using an old lady’s credit card. It may be someone with his same name, but the picture (low quality) vaguely resembled him. so now I’m left wondering.

On this day, I learned that Liquid Nitrogen (N2) makes ice cream fast! Like fifteen minutes fast! (fast!) Coolwhip ice-cream is fun and low-fat, but not quite as fulfilling as the Real Deal. Also, speakers are still just as hard to get right as they were in University Physics II, but at least now I’m not graded for it :D
Also, kids love physics experiments.

I learned that Bill Nye was full of crap when he said you could find a four leaf clover in a square meter.

I learned that the parking deck has jasmine growing on the north wall, and that there are some HUGE pinecones growing out by the business buildings.

I also learned that the music video to Baby Got Back is very. . . ’90s.

I learned that you shouldn’t live in Phoenix, AZ if you want to criticize police forces. Makes you wonder what they’re hiding, to overreact like this.

I learned about a quirky web comic named Buttersafe

I also learned that Grave of the Fireflies is omg sad :’{. I mean, I’ve known for years that it’s supposed to be sad, but it’s SAD. omg. I also learned that the US used fire bombs on Japan, useful because of the Japanese’s habit of building houses out of wood :X

On this day, I learned that Row week is HUGE. This is the University of Arkansas’s fraternities’ big party week. Each participating house erects a wooden fence around their property, partly tradition, I believe, and partly to avoid fines for public intoxication. They spend thousands of dollars setting up sound equipment, hiring musicians, putting up lights. The lines outside one house supposed to have brought in Lil’ wayne for the night had lines going for a quarter mile in each direction, with two cop cars parked across the street. Any girl gets admitted, but males have to be on The List.

I learned that while you’re taking in these sights, it’s kinda nice to smoke when everyone’s all drunk around you. The smell of liquor lends itself to getting your own personal buzz.

I also learned that running around with friends = fun, especially if it turns out that the microphone in the theater has been left on, and no one is around to make you get out. There was a door to a closet full of props (hats?), a grand piano, a men’s small Razorback shirt (red), a set of graduation robes (black), a blackboard and chalk, and a stairway leading down to a fire exit and an unmarked private bathroom. There were several sets of nine volt batteries on the podium, and full access to the light box. Funtimes.

I learned that the difference between a force on a rope and a weight on a rope is the freebody diagram of the weight. The mass of the weight affects the tension on the rope.

On this day, I learned that Dynamics homework sucks.

I learned what our ozone layer may have looked like without CFC intervention, and that the Montreal Protocol was responsible for banning the chlorofluorocarbons. (FUN FACT: I learned about CFCs when I was about 7. My dad was studying to become a certified HVACR tech and had this three inch by ten inch by twelve inch book to study)

I learned what happens at Netflix!.

I learned that as hard as it may be for me to choose a gift, it’s much harder for dignitaries.

I also learned that Powerhouse on Dickson St. actually serves primarily seafood; this would explain its full name, which I hadn’t heard in its entirety: Powerhouse Seafood and Grill. A little pricy, but not too bad (coconut shrimp YUM)
