DRAWINGGGGGGGGGGGG!

6-30-2013

Egh, all they look the same. They calm me down though, so the world’s just going to have to deal.

I forgot to play Minecraft!

Stuff I should have done today:

  • Written the test for my class.
  • Worked on my data stuff for my other job.
  • Gone walking EARLY to beat the heat so I could actually go on the trail.

Stuff I actually did today:

  • Screwed around until 3 PM.
  • Walked 16 miles…at the rec center. ‘Cause I was too lazy to go walking earlier and it was too hot to walk outside.
  • Wrote smutty fan fiction.
  • Watched a bunch of Achievement Hunter vids (they pretty much rule my Saturdays)
  • Drank copious amounts of Red Bull.
  • Drew some crap.

Good day?

Holy crap, The Hunchback of Notre Dame is on Netflix?

I know what I’m watching tonight.

I pretty much grew up on Disney movies and this one used to scare the living crap out of me for some reason, but now it’s definitely my favorite. I don’t know if it was the whole “going to Catholic school for six years” thing or what, but I really find myself enjoying books/movies/entertainment with religion as a main source of struggle or conflict. Such themes have always stricken me as being very honest and very impactful. Hunchback was one such book and movie; The Crucible was another. There is a bunch more, too, but for whatever reason I’m totally blanking on everything else I’ve ever read/watched right now. Probably ‘cause it’s like 5 AM and I had Red Bull and I’m feeling really antsy tonight.

Also, tell me this isn’t the best opening ever (I know I’ve posted this on here before, but screw it):

The Graffiti of Ag Sci Room 106

As I mentioned on a previous blog, I’m teaching next fall. But rather than my section being held in TLC 40 like pretty much every STAT 251 class ever, I’m going to be in Ag Sci 106.

Even though my dad’s taught in there since like the dawn of time, I’ve never actually been in there. So that’s what I did today.

6-27-2013-a

BIG ROOM.

These chairs look like they’re from a different era.

6-27-2013-b

As I was walking around on the stage in front, I noticed that while most of the desks had writing/graffiti on them…

6-27-2013-c

…Some of them had super intricate designs that were really quite impressive. Check it:

6-27-2013-f

6-27-2013-g

Awesome.

I didn’t find any graffiti about my dad (he’s been teaching in that room since the ‘80s), but I didn’t really look, either.

Helium’s Ghost

It took some very specific Google searching, but I finally found a math-related survey! It’s short, but it must be done. Because that’s what I do.

What got you interested in math?
Statistics, honestly. I was decent at math as a kid but I never really thought I’d be super interested in it. Then once I got into stats I HAD to take more math, so it just kind of developed from there. And once I took calculus? Yeah, then it kind of got crazy. I still don’t feel like I understand ANY of it on the same level I understand stats, but I’m hoping that the more I take the better understanding I gain.

What is your favorite area of mathematics?
Depends on what’s considered an area. Is statistics still considered an area of math or is it its own separate being? Or is it in the cluster of “applied math”? So if stats counts, then stats. If not, then calculus. I really, really like calculus.

Who is your favorite mathematician?
Gee, I have no idea.

What is your favorite mathematical symbol?
The integral symbol is definitely my favorite. I love writing it and the way it looks. And yes, I liked this symbol even before I knew Leibniz came up with it.
6-26-2013-a
I also like the symbol for perpendicular lines, for whatever the hell reason.

What is your favorite equation, formula, or theorem?
If it isn’t evident by now, I really like calculus. So I’d have to say the Fundamental Theorem of Calculus is probably my favorite theorem.

Favorite math joke?
Oh god.
Stats one:
“The larger your sample size is, the more confident you can be that your sample mean is a good representation of the population mean. That is, the ‘n’ justifies the mean.”

And this:
6-26-2013-b

 

OOH, and this. Not a math joke per se, but screw it, it’s awesome:
Newton, Leibniz, and Pascal were all playing hide-and-seek, and it was Leibniz’ turn to count. Pascal immediately runs off and finds a great hiding spot, while Newton simply stands out in the open and draws a one-meter square on the ground around himself. Leibniz finishes counting, and when he looks up, he sees Newton.
“Aha!” he yells, “I found you!”
Newton responds, “No, you found one Newton per square meter–you found Pascal!”

Who is/was your favorite math teacher in school?
My calc I teacher was fantastic. She was easily the best math teacher I’ve ever had. She was no-nonsense about everything and very factual, but was also very clear about what we were doing and why. And she also put up a sheet of math-related cartoons/puns on the overhead at the beginning of every Friday’s class, so that made her even more awesome.
If you ever have to take calc at the U of I, look for a class taught by Judi Terrio.

Do you have a mnemonic device (like PEMDAS) to remember something math-related?
I had a bunch of stupid things I’d say in my head to remember the trig substitutions, but I eventually just memorized them without the sayings because I was getting the sayings mixed up.
Getting your own mnemonics screwed up: welcome to Claudia Land.

END!

Shouldn’t a minor in geology be a “miner”?

So Megan and I were talking this morning (“What?” you say. “Social interaction??” I KNOW, RIGHT?!) and we concluded that if there ever were a time where time travel was invented and we were able to drag someone from like the 1600s to the present time, the first thing we would show them would be a vacuum cleaner.

Because that’s probably the most futuristic-looking thing we’ve got.

Seriously now. If I were to bring someone from 300 years ago into the present time and say, “we’ve developed technology that allows us to launch ourselves into space,” and ask them which of the following two objects is the thing that allows us to do so, which do you think they would pick (ignoring scale)?

6-25-2013-a6-25-2013-b

I’d be tempted to pick the second object. It would roll along a runway like an airplane and then launch once it hit a certain speed.

Fun fact: the Saturn V Rocket was a Dyson in disguise.

Duders, I finally bought new socks! Check this noise:

I LOVE those Starry Night socks. So fantastic.

SERIOUS BLOG (sorta not really)

Alright fools, settle in for a long read. I haven’t had a “serious” blog in a while and due to some recent events I feel the need to finally talk about what I’m going to talk about in this post, so this shall be a long AND serious blog (aren’t those just the BEST?)

But never fear…there is some fun to be had. This blog is about SEX!

SEX SEX SEX SEX SEX!

(Or lack thereof.)
(Whatever.)
(So I guess it can’t be too serious if there’s sex involved, right?)
(Right.)
(Sorry, I’m really hyper.)

Kay.

Just a warning: for any of my readers for whom sexual assault/molestation is triggering, this contains NOTHING like that, so there’s no need to worry about that. It’s more a “stupid grade school kids do stupid stuff” type thing, alrighty?

ALRIGHTY!

I’ve never told anyone about this, mainly because for the longest time I never really thought much of it. But the more I’ve pondered it, the more I realize that it’s probably had a bigger effect on me than I’d ever actually considered when I was younger.

So as some of you know, I went to a Catholic elementary school. We had “religion class” every day, we had Bible story coloring books, we put on these huge Bible-themed musicals every winter and every spring, and we went to church every Friday morning.

The school was also pretty strict about the things you might expect a Catholic school would be strict about. We couldn’t cuss—“crap” would get us sent to the principal (who was a nun, of course). We couldn’t talk about “naughty parts.” We couldn’t take the Lord’s name in vain, we couldn’t wear holey clothes (holy clothes were another story), all that kind of stuff. So you can probably imagine what our sex education was like.

Sex was bad and anyone who ever had sex was bad and even if you THOUGHT about sex you were bad and even the word “sex” was bad and everyone who had ever had sex ever (outside of marriage and/or for recreation) was bad.

In fifth grade we had a special night session where we sat in the auditorium and listened to a guy who did nothing but tell us about 11-, 12-, and 13-year-old girls who got pregnant their first time having sex and were therefore SUPER bad. We were basically told that if we had sex out of wedlock (and even if we had sex DURING wedlock but it wasn’t for procreation), we would be shunned by the Lord FOREVER and would never get into heaven.

Now as ridiculous as that might sound to people who don’t believe in God or heaven or anything like that (those of you who are saying “haha, no one would ever REALLY believe that!”), let me remind you of something: this stuff is being hammered into the heads of young children, most of whom leave the religious-heavy environment of school to head to homes that are as equally religious-heavy. I didn’t—I went home to my atheist mother who was always like “PFFFFT JEEZUZ”—but most of these kids had parents who were VERY religious and therefore by age 11 were deeply, deeply into Catholicism and truly believed this stuff.

So by the time we’d gotten halfway through fifth grade, we all were primed with this idea that sex outside of marriage and for reasons other than procreation would, 100% of the time, result in ACCIDENTAL BABY that no one would ever want and therefore was like the worst thing you could do.

(Aside from spitting chewed-up holy wafers at each other.)
(Which we did.)
(Blasphemous little heathens.)

ANYWAY.

So sex = bad, people who have sex = bad, blah, blah, blah.

Fast-forward a bit to spring of fifth grade. Back then I actually had a fair number of friends and we were all pretty close (heck, our class size was like 23, so we kind of had to bond with each other). Two of the people in our class, Jack* and Jill*, were related somehow (I’m still not sure exactly what they were), and for whatever reason in like March of fifth grade year they decided to have a huge sleepover at Jill’s family’s farm.

It was mostly a bunch of us girls—there were two dudes there, Jack and Joe*. We watched Space Jam and ate pizza and all that fun late ‘90s nonsense, then decided to just all stay up all night. The girls, including myself, were downstairs in this funky basement room thing with our sleeping bags all sprawled out everywhere. They wanted to watch another movie or something and I didn’t, so I decided to go see what the guys were doing.

Joe and Jack were hanging out in the kitchen and I joined them, and in a very short amount of time—because we were in fifth grade  and rebellious and hyped up on sugar and Michael Jordan—we decided to go up to the attic and play Truth or Dare.

And as per the unspoken rules of Truth or Dare, things got dirty.
Well, I guess “dirty” is a relative word.

You know that “sex” thing that we weren’t supposed to even THINK about? Well, we thought about it. And really, thinking about it was all we did. I have to say here that Jack was never the brightest crayon in the box; he had the brilliant idea to dare me to let him have sex with me, to which I was like “OH GOOD LORD NO” (see, I’m not a TOTAL idiot) and luckily Joe thought the same as I did. So he came up with a milder dare for us: Jack and I would take off our shirts, he would crouch on all fours above me as I lay on my back, and we would “fake” having sex.

Which was okay with both of us, so we did that.

Let me stop here and emphasize a few points:

  • Pants stayed ON. Hell, I think we still had our shoes on.
  • By “crouch above me” I meant that he literally stood on all fours above me as I lay looking up at him. Our bare skin didn’t even touch.
  • I didn’t have boobies at that point, so it probably looked like two shirtless dudes trying to do some weird yoga together, now that I think about it.
  • “Faking sex” meant panting “OH JACK!” and “OH CLAUDIA!” while he wiggled his butt around in the air as if he’d taken an enema of bees.
  • Again: WE. DIDN’T. EVEN. FUCKING. TOUCH.

So we did that for like two minutes before we got bored of it. The rest of the night involved mooning the empty barn across the way and licking various farm animals (that was actually probably the dirtiest part of anything that went on that evening).

The next morning everything was back to normal. No one—apart from myself, Jack, and Joe—knew about what went on upstairs, and so nothing was said about it.

Now fast forward to the week post-sleepover.

St. Mary’s is a pretty tight-knit school. Due to its size and its number of mandatory full-school activities, everyone pretty much knew everyone else. Usually this wasn’t a bad thing. But when it came to rumors, things spread like the plague.

You can probably guess where I’m going with this.

I think it was the Tuesday of the week after the sleepover. We were obsessed with 4-square and played it incessantly at recess. During our lunch-period recess, I distinctly remember standing in line behind one of my girlfriends, waiting to play, and she leaned over to me and whispered, “So you had sex with Jack, huh?”

And of course I was like, “Who told you THAT?” And it turns out she heard it from a friend who heard it from some other friend who had heard it from another friend who had heard a whole group of people talking about it.

I remember being in total shock about this. Obviously I didn’t start the rumor, so I knew the source of it had to be Joe or Jack. The following day during lunch I remember walking over to where he was sitting in the cafeteria and just blatantly asking him.

“Are you telling people we had sex?”
He just smiled and nodded.
“Why? We didn’t have sex.”
“We kinda did.”
“No, we didn’t. We had our pants on.”
“Well, that’s still kind of sex.”

The group of guys at his table were kind of staring at us by that point and I, of course, was about ready to cry (because that’s just how I am), so I just said, “No, it’s not! Stop telling people we had sex!”

Surprisingly, he agreed to this quite readily (I think my being upset really freaked him out and he didn’t want some crazy chick freaking out in front of his friends) and I honestly don’t think he continued to spread the rumor. I don’t think he was smart enough to be vindictive like that.

But the damage was already done. Walking back to my table, I was getting DEATH STARES from people. You know those over-dramatic teen dramas were a rumor is being spread about someone and you can hear people whispering about said someone as he/she walks down the hallway? That’s literally what it was like. I could HEAR people whispering about me.

I had sex. I was a slut. I was a sinner. I was a bad girl who should have known better. I was dirty. I was to be publically shunned.

Which was pretty quick to happen. I lost a large proportion of my friends over the rumor because they were convinced that I was a bad seed and that I had brought the shunning upon myself by behaving in such a blasphemous way. I honestly don’t think anyone willingly spoke to me (apart from teachers, of course) for like a month after the rumor began. People were more than ready to cast me aside as someone who had committed an egregious act and therefore didn’t deserve to be bothered with.

And you know what the worst part of all this nonsense was? The part that I didn’t really consider until probably three or four years ago? I actually believed them. I was on their side. I was a slut. I was a sinner. I was a bad girl who should have known better. I was dirty. I was to be publically shunned.

EVEN THOUGH I DIDN’T ACTUALLY DO ANYTHING.

EVEN THOUGH IT WAS
JUST
A
FUCKING
RUMOR.

I felt shame. Buckets and buckets of shame.

(What’s the unit for shame? Prevention’s in ounces; is shame in liters? I’ll say it’s liters.)

I felt liters and liters of shame. I had never felt so shamed in my life (and actually, I’ve never felt so shamed since).

In fact, I had fallen so far into my peers’ same belief that I had actually convinced myself that Jack and I did in fact have sex. I know that sounds obscenely stupid and you all probably think I’m an even bigger moron than you originally thought, but let me say a few things here:

  • I was always a really shy kid. Fitting in naturally wasn’t really something I did because I’d never taught myself how to do it. Because I never really had the social graces to counter anything my peers did, and because peoples’ opinions of me had always held a fair amount of sway (I WAS just a kid, remember), I figured that they were right in disliking me.
  • It was my claim that the whole thing was a rumor against the rumor itself, which was perpetuated throughout the school by every single other person who heard it. I never heard a single person express anything like “no, actually, that’s a rumor. She didn’t do it.” I didn’t really have much backing to defend myself.
  • As I mentioned, this idea of “sex = bad” was BEATEN INTO OUR HEADS. Some kids vehemently believed this and were not afraid to show it. Hell, I was getting rocks and bark and sticks thrown at me for a while there.

So yeah. As stupid as it sounds, that’s what I felt. Multiple times, I was a breath away from telling my mom that I’d had sex and that I thought I was pregnant (another stupid belief; I hadn’t started my period yet, but I was CONVINCED that I’d had sex just as I was supposed to have my first period, so I was in fact pregnant). Thank Jeebus I never said anything to her.

So now that I’ve rambled about this for…*scrolls up*…four pages, you’re probably wondering why in the hell I’m telling you all this, and what it actually means. “This happened when you were 11,” you say, “and obviously you didn’t have sex or pop out a spawn or anything like that. So who cares?”

Well, as I said, I’d kind of pushed this whole thing aside for many years. I never really thought much about it after things finally started going back to normal (I think the fact that I didn’t pop out a spawn convinced a lot of people that I actually hadn’t done anything), and in fact didn’t really think about it at all for several years.

But when I was in my second semester at UI, Sean and I started talking over Messenger about sex. I think I’d told him that I was very cautious about sex and my virginity and whatnot, and he was curious as to why. We didn’t hit on this particular point of my past specifically, but the more I thought about why I was so cautious about such things, the more I kept coming back to this one incident.

It’s really, really hard for me to separate sex from shame…at least for me personally. I don’t think that everyone who has sex should feel shame (and don’t automatically shame my friends when they say they had sex or whatnot). But when I think about myself and I think about myself actually having sex (vaginal sex; I don’t have an issue with oral, apparently. Giggity.) I just can’t shake that feeling of impending shame. If I have sex, I feel like I will feel shame and will feel like I deserve to be shamed, and I think that that belief is quite clearly tied to the incident that happened in fifth grade.

Again, I know—it sounds really, really ignorant of me. You’re probably thinking “holy hot damn, this girl is a fucking moron!” But please note that I’m not saying that I should feel shame or that I should be shamed for having sex. I’m saying that that’s how I would feel.

I think those are very different things.

And so why the hell am I talking about this today, the 23rd of June, 2013?

Because I don’t have anything else to blog about

I think it’s because of all the women’s reproductive rights nonsense going down in Texas and in the country in general as of late. The whole notion of shame being so closely connected to sex and how “in the news” it all is just keeps bringing me back to that feeling. It’s an interesting visceral response. And it’s one of the main reasons that I have difficulty watching the debates or listening to anyone talk about the debates or even read about the debates, because the whole thing just makes me incredibly anxious.

BUT ANYWAY.

Holy crap, this is a long blog. Haha, sorry.

I just figured…why not finally write it all out?

*Names changed to protect the innocent (?)

What a Titillating Title!

Well, apart from Migraine Part II, today was pretty good:

  • 98% on calc final, A in the class overall.
  • 750 miles reached! Halfway to my goal and about a week ahead of schedule.
  • Bought socks.
  • Heard from Nick for the first time in awhile and he said he’s sending me something in the mail. He wouldn’t tell me what it was, so that means it’s probably going to be hilarious.

Now that I can see again and my head isn’t imploding, I’mma play Minecraft for like twenty hours. Be back later.

OH CRAP SORRY PASCAL

So I hadn’t checked my little mathematician birthdays database in awhile and decided to check it yesterday. It turns out I missed Pascal’s birthday by a day. He was going to get my blog yesterday but I was distracted by freaking out about my final. I’m still freaking out about my final, but I have nothing else to blog about related to it. So Pascal shall get my blog today instead!

Though he only lived the 39 years between 1623 and 1662, Blaise Pascal was an incredibly accomplished mathematician and inventor. He was educated by his father and was still in his teens when he began to explore advanced topics on his own.

He was interested in math (particularly geometry) early on; when he was 16 he wrote an essay on conic sections that was so advanced that Descartes read it and thought that Pascal’s father had actually written it for him.

Little Pascal was also very interested in the idea of a mechanical calculator, and he was strongly motivated to produce the first working prototype of what was called the “Pascaline” in 1642 to help ease his father’s work as tax commissioner for the king of France. The calculator could do addition and subtraction* and was a great help to his father, but because of its cost it failed to be a commercial success.

Probably Pascal’s most famous contribution to mathematics is Pascal’s Triangle and the closely-related Pascal’s rule which states how the triangle is to be constructed. The triangle displays the binomial coefficients resulting from the binomial theorem along with other really cool properties (might have to do a blog just on his triangle here in a bit…). The development of this triangle led to conversations with Fermat, and the two collaborated together to develop probability theory.

In addition to his contributions to math, Pascal also gave the world the hydraulic press, the syringe, and did a whole ton of experiments with vacuums and hydrodynamics (he’s got the SI unit of pressure named after him as well, though that obviously happened much later). Some of his most famous demonstrations of the effect of elevation on atmospheric pressure involved carrying barometers to the tops of churches to see what happened to the mercury levels.

Cool dude, huh? See? 17th-century Europe!!

BLOG COMPLETE!

*The Pascaline was what Leibniz was trying to improve on with his Step Reckoner by including also the functions of multiplication and division.**

**Yes, I have to mention him in every post.

Noooooooooooooooo

Calc III is over. :(

It’s a sad day! It was one of my favorite math classes.

I just seriously hope that the answers to the 10-question final were 4, 1, 4, 6, 6, 1, 6, 55/23, 4, and 1, because that’s what my answers were. We’ll see. I gave myself a 60-point leeway to get an A with my homework and midterm scores and I don’t THINK I made 60 points worth of mistakes, but who knows. I’m fantastic at screwing up. I missed one point on the midterm because I completely abandoned a negative sign like two steps into a cross product. FAIL!

Also, migraines suck.

Sometimes a Blog is Just a Blog

Man, my blogs have been all over lately.

Today’s going to be no different, so you know what that means.

BULLETS!

  • I keep forgetting to mention this, but I am teaching in the fall. I’ve got the Tuesday/Thursday section again (yay!) and I’m teaching in the same room in Ag Sci that my dad teaches Envi Sci 101. That’s hilarious.
  • I’ve really been getting into 17th- and early 18th-century Europe lately. Not just the mathematics aspect, but all of the scientific revolution/Enlightenment in general. This time in history has always really intrigued me ever since I first really had a chance to learn about it. There’s just so much scientific advancement and so many great minds and so much stuff happening all in conjunction…I wonder what it would have been like to have experienced that.
  • Speaking of the 1600s, can we take a second to appreciate Leibniz’ mechanical calculator? More specifically, the Leibniz wheel that he invented to actually make it work? Leibniz wheels were actually used in calculating machines up until the 1970s when the electronic calculator became available to the public. Seriously, how incredible is that?
  • Speaking of Leibniz’ calculator, can we take another second to appreciate Leibniz?* Actually, take all the time you want. I’ll wait.
  • I dreamt last night that I had “Don’t Forget to Add the Arbitrary Constant” on my headstone when I died. Miiiiiiiight have to make that happen (of course my grave will be empty, ’cause you all promised to scatter my ashes over Leibniz’ grave, right? Right.).
  • 2 Stupid Dogs almost won a daytime Emmy? Seriously? I used to actually enjoy that show and all, but for what would they win an Emmy?

I guess this blog really wasn’t all over. It was just mostly disguised as a Leibniz rave with just a little bit about 2Stupid Dogs thrown in. Oh well.

*Yes, I know, I’ve been dropping his name more than usual lately. That’s because I’m in the midst of reading a biography of him (that one my mom bought me like four years ago. I wanted to make sure I knew enough about calculus before getting into it) and every page is making me squee. I freaking love that man so much, you people don’t even know.

You know what I’m good at?

Nothing.

Dear Phoenix Suns:

Why is your mascot not a guy ablaze in a fire-safe suit?

Wait.

WHY IS YOUR MASCOT NOT THE SUN?!?!

It’s not like he wouldn’t show up to the games if you just open a few blinds.
Or better yet, retrofit your stadium with a sun roof like those stadiums whose roofs open.
“Everybody give it up for the Phoenix Suns’ mascot, The Sun!”
Everyone: “OH GOD MY EYES!”

The Suns should officially be the most terrifying NBA team ever.

“Aw, how cute, you guys are the Chicago Bulls?” *roasts* “Now you fools are the Chicago STEAKS!”
“The Orlando Magic, huh?.” *solar flare* “2 MILLION DEGREES KELVIN! THERE’S SOME MAGIC FOR YA!”
“Houston Rockets, we have a problem!”

It’d be an interesting match-up with the Miami Heat, though.

Sorry, I’m done.

Ready for Another Stupid Claudia Dream?

ME TOO!

As I was drifting off last night I had kind of a dream/flash of an idea: someone needs to make an ABCs book about statistics!

Like…A is for Anscombe’s Quartet, B is for Bayesian Inference, C is for Correlation, D is for Design Matrix…

Oh waitwaitwaitwait. There could be an “applied stats” alphabet and a “theoretical stats” alphabet. That way we could get more topics. AND EACH COULD HAVE A LITTLE POEM!

Yeeeeeah.

Of course I’m sure this has been done, but still…wouldn’t it be cool? I’d read it to my spawn if I ever have a spawn (that poor child would be screwed up from the beginning, though, so I probably shouldn’t have a spawn).

(I would name my spawn “Spawn.”)

(Or “Leibniz.”)

(Yup, shouldn’t have a spawn.)

Sweet Hot Cajun Invasion, I’m Hyper

The closer I get to this calc final, the more math puns I want to make.

The closer I get to the edge of my chair, the more I want to fall off.

The closer I get to removing all semblance of sanity from my blogs, the more my readers are thinking, “dear god, why did I decide to follow this inanity?”

HAR HAR HAR RED BULL TIME IT’S NOT LIKE I NEED IT BUT WHATEVS!

JEEBUS TAKE THE WHEEL!

Also, my hair’s long enough to braid now. Woo!

TWSB: We’re In the Matrix

The matrix of LINEAR ALGEBRA!!!

So someone asked the awesome dudes at Ask a Mathematician/Physicist why determinants of matrices are defined in the strange way they are. And one of the opening sentences of the Physicist’s response was:

“The determinant has a lot of tremendously useful properties, but it’s a weird operation.  You start with a matrix, take one number from every column and multiply them together, then do that in every possible combination, and half of the time you subtract, and there doesn’t seem to be any rhyme or reason why.”

That needs to be a textbook definition somewhere.

Anyway. This was an especially interesting read for me, since we just learned about the role of the Jacobian matrix’s determinant when performing a change of variables for multiple integrals.

The Physicist has an excellent explanation of it (along with pictures!), but it basically comes down to the fact that the determinant of a 3 x 3 matrix, if we treat the columns of the matrix as vectors, is actually equal to the volume of the parallelepiped (coolest shape name or coolest shape name?) formed by the vectors. Think about if you have two vectors in the xy-plane. You can extend vectors out from each of the tails of the vectors so that you have a parallelogram like this:

6-14-2013

Finding the determinant of the 2 x 2 matrix that describes those two vectors is the same as finding the area of the parallelogram formed by them. Add one more dimension and you get a parallelepiped for your shape and a volume for your determinant.

This has a buttload of applications—like I said, when performing a change of variables when doing multiple integration, but also for finding eigenvalues/eigenvectors and determining whether a set of vectors are linearly independent or not.

I was actually planning on making this a longer blog with an actual calculus application, but a) formatting that would take like 80 years for me and I’ve actually got to study sometime tonight and b) I’ve fallen into the “polar coordinates” article on Wiki and I don’t think I’ll be getting out anytime soon. THEY MAKE ME HAPPY, OKAY?!

Bye.

MORE CAPS LOCK = MORE STUPID PUNS

WHY AM I ALLOWED TO HAVE FLASH?

I SHOULD NOT BE ALLOWED TO HAVE FLASH.

(…or Red Bull)

Goin’ Green

I’M DOING IT AGAIN!

Today we learned about Green’s Theorem. So who is this Green fellow?

[Edit: Okay, originally I was just going to talk about Green ‘cause while Green’s Theorem is just a special case of Stokes’ Theorem, we haven’t learned the latter yet. But turns out both Green and Stokes are named George and that’s hilarious, so we must press on and speak of both.]

So who are these two fellows?

George Green lived from 1793 – 1841. Like what seems to be a large proportion of mathematicians at the time, he was British. He lived in Nottingham. There are two reasons why these are interesting facts:

1. Nottingham, at the time, wasn’t really burning it up intellectually. Only about 25-50% of children received any sort of education, and Greene himself attended an academy for only one year when he was 8. It took him until age 36 to gather enough money (and free time) to afford a higher education (and he died when he was 47, so unfortunately he didn’t have too much time to enjoy it).

2. Despite the setbacks as far as formal education goes, Green was a very smart dude. He was largely self-taught (obviously) and once he finally got to Cambridge he pretty much kicked ass. What’s most interesting, though, are his studies in math. Historians aren’t exactly sure how Green reached the understanding of calculus that was necessary for developing his theorem. He likely used the “Mathematical Analysis,” which was a form of calculus Leibniz developed, but this was during the post Newton-Leibniz controversy over calculus and England pretty much forbade the use of everything calculus-related that originated from Leibniz. ‘Cause they had Newton’s calculus. Never mind that Newton’s notation was inferior and didn’t lend itself to the applications/developments that Leibniz’ notation did and that forbidding the better notation/methods from the England set the country back in mathematical advancements for like a century.* But somehow Green got a hold of it and made his improvements and came up with his theorem and was generally awesome. (LEIBNIZ POWER! Okay, I’m done).

And what about George Stokes? Who was he? Stokes’ life overlapped the end of Green’s life (1819 – 1903). Stokes was Irish and rocked the fields of fluid dynamics, optics, and mathematical physics. He actually did quite a variety of things, so I’m just going to list a few.

  • He came up with a way to calculate the terminal velocity of a sphere falling in a viscous fluid (Stokes’ Law!)
  • He expressed a mathematical description of rainbows using a divergent series, something that wasn’t really understood just yet by most.
  • He was secretary and then president of the Royal Society.
  • He wrote a paper in which he tried to describe the variation in gravity across the earth’s surface.
  • And, of course, Stokes’ Theorem in math.

YAY GEORGES!

Sorry, I’m going to keep doing these little mathematician snippets until…well, until I feel like stopping. So ha.

I accidentally my life

Don’t you hate those mornings where you wake up and you realize just what a pathetic failure you are?

OH WAIT THAT’S EVERY MORNING.

[ignore me]

These blogs are gonna suck for like the next two weeks, FYI.

It’s teachin’ time!

YAY!

These next two weeks are going to be insane, though. Teaching, finishing calc, and doing the data analysis stuff. But calc’s over in two weeks and then I have no more classes until fall.

I anticipate a weekend of solid Minecrafting once these two weeks are over.

DONE!

Every once and awhile I just find Family Guy obscenely funny (this blog has nothing to do with Family Guy, just an observation)

This is…actually pretty good. I heard the first like fifteen seconds and was like “NOOOOOOOO they be ruinin’ mah current fave song!” but then it got snazzy.

Also, Doin’ It Right is now my third most-played song.

Freaking Daft Punk.

Let’s add this to the “This is Why Claudia Shouldn’t Make Jokes” list.

Also, one of the bullet points on this guy’s “43 Ways to Start Making Money” pages is “get a job.” I can’t tell if that’s hilariously snarky or just jerk-tastic.

I done speak good

A few of my friends posted this on their Facebooks and so I decided to check it out and then post it here ‘cause it’s pretty freaking snazzy. I found the link to the whole data set here.

Some of the interesting ones to me:

  • I pronounce “crayon” like “cran” (rhymes with “can”), which is the common pronunciation in Minnesota/Wisconsin/Michigan/that region.
  • I pronounce “realtor” as “reel-uh-ter,” which is a little more common in the Midwest/upper south.
  • I pronounce “roof,” “room,” “broom,” and “root” with the same vowel sound, which is very common in the south and New England.
  • My “route” rhymes with “out” and that would probably get me beat up in New England, who strongly prefers that it rhyme with “hoot.”
  • I say “garage sale” rather than “yard sale” or “rummage sale.” Garage sale is common in Tornado Alley.

Cool stuff!
