Vivid Dreams
And then I spent an hour (or two) making sense of the formal definition of a function, until I REALLY understood it for sure.
I understand it now. Math makes even more sense when you understand the reasons behind everything.
It's so dang cool.
I had a dream about calculus last night. And chemistry.
This took place in a ginormous building that had classrooms, labs, a giant library/computer room on one of the higher floors with windows taking up the ceiling and walls (it sort of reminded me of a terminal), escalators, stairs; almost like a mall/terminal that had been gutted and turned into a school, but even bigger, with, like, five floors and a basement.
It was the last day of school. For some reason, I was rushing around the school. I could see into the classrooms as I ran past: in the basement were the lab classrooms, college-age kids slouching on the lab stools, head on their hands, waiting for the class to be over as the teacher just lecturelecturelectured; up the stairs, skip the first floor, which had tons of students walking around, going to classes; on the second floor, chemistry classrooms, where I see my chemistry teacher (who had been teaching my trigonometry class also), and I paused to talk to him about the class and to ask him a question about my calculator and some assignments, he told me that I had to turn in my calculator before a certain time and that I'd better hurry, since it was almost that time, so I was running, running, running (and this is where I realised why I was running); up to the third floor, where there was a cafeteria; up the stairs again, running so fast past the fourth floor; fifth floor, where all the math classrooms were, and also the giant computer lab, and there were tons of students on the computers, some walking around, doing some last-minute last-day stuff, discussing things with their teachers.
When I got up to the fifth floor, my chemistry teacher was there, and I gave him my calculator. It was a few minutes past the time, however, so he took points off of my grade. He had these eight blue tickets, like the kind for raffles, only larger. He tore off five of them, kept those, and gave me the remaining three. I wasn't given the five because of the calculator being turned in late and because I had also lost points for the assignments I had been asking about. This was on top of a lot of points that he had taken off my grade because of the assignments. I was very disappointed and mad at myself, but I didn't hate the teacher, because he was cool, and it was mostly my fault (This part of my dream mirrors real life: a similar thing happened with my stats teacher, where he didn't count an assignment, so I got a B in the class, but I still like the guy. He's a good teacher. I'm thinking that this part of my dream also translates to my knowing I could have done better than I did in my classes last semester, which really makes me mad at myself. I could have done better.)
But there were still three tickets left, and he gave those to me, and said that they were each worth 32 extra credit points on my final exam. I was a bit alarmed, because I didn't know about this exam (I thought I was done with all my finals), and because if there were eight tickets that I could have gotten, and they were each worth 32 points, then did that mean that I would need all those points because the exam was so hard and I would miss a ton? Then he gave me the take-home final that was maybe 100 pages thick, all word problems that combined trigonometry and chemistry. He explained that it was due on January 4th, the day before winter semester began. I looked at the first problem (it took up half of the first page just explaining the problem), and I was scared for my life. I knew it was going to take FOREVER. Later, I realised that I wasn't sure whether I was supposed to take it in the testing center (which would have been bad, since the testing center was closed for the break) or at home, and I couldn't contact my chem teacher, since it was break. So I was moderately stressed about the test, and upset at myself for the points and the five tickets that I lost. This was for trigonometry, and I thought for sure that I'd get an A in trigonometry, but now it looked as though I would be lucky to get a B. I was very disappointed in myself.

Thoughts
People really do change.
It's so weird.
Life moves on in other places, not just where I exist.
Other people grow up too, other people live their lives.
It's so weird.
Life is so weird. People are so peculiar.
It can seem so incredibly, laughably simple, or so hugely, incomprehensibly complex.
It's so weird...
The Major and Minor of it all.
The only disappointing thing is that any time anyone will ask me what my major is, and I tell them, I'll get that pause, and you know they're thinking, "...BOring!" and then they'll verbally add the half-hearted reconciliate "Oh...cool...."
Oh well. I'm going to love it.
And the plan after college is still graduate school, but for econ, not statistics!
I'm so stoked.

Chloe's got a temporary job. COoliO
I doubt I'll be able to replicate it unless I am again in the zone.
Which happens once in a red moon.
I worked at a bread-baking place today. Not baking bread, though. But other stuff. And it was fun. 8 hours of fun. And I get paid to do it. That seems weird. I even got free bread.
I want to get my hair colored and cutted. Perhaps I shall.
Today, I told someone what my major was, because they asked. They didn't know me, and neither did they know I'd been frustrated with the whole thing. But when I told them my major, it felt right. So I don't think it's jinxed. But all the same, I want to change it and have it be mine, officially, antes de I tell everyone. Not that anyone's going to be excited about it. Heh.
It's 10pm. Tengo hambre. No quiero comer. Y manyana, trabajo. I feel like watching a movie. YouTube! A Beautiful Mind, or Cinderella Man? We shall see.

Calculus and Conversation
I was more excited about the calculus book.
It was like an early Christmas.
I spent the entire day reading: reading my bio book (I'm dropping my bio class, though); reading my econ book; reading my calculus book; reading books for school. It was amazing. And I made a connection between calculus and statistics. On my own. And I even wrote it down on this little white board that we have in the apartment, and then took a picture of the white board so that I'd always have my discovery. I told my sister about it when she called, and she said I was a geek. No. I'm a nerd. But I'm hot, so it's okay.
I was talking with a friend tonight about everything from putting human life and the Atonement and love into a formula to missions. It was fascinating. There is so much to learn from everyone. And I know that the things I learn from the people I meet now will be important in some way later in life, and so I'd better pay attention. It's just amazing, what one can learn from others.
Oh, and I shan't put my major upon this blog, because it seems that every time I make it concrete, it's wrong, so suffice it to say that math shall be my minor and my major shan't be biology, nor will I do a double minor. Perhaps I'll put it up later. But I'm for sure for sure I'm in the right major now. And it is final and forever. No more changes. So there.
I'm so stoked for next semester. It'll be the best yet.
Looooveeee.

The Latest and Greatest
But really, I was having minor complications. I didn't know what to choose for my minor. It was between biology and economics. And then today, it hit me: double minor.
I realised that the only thing I'm really passionate about in biology is human anatomy and physiology, and so I decided to go with the entire major because I didn't know what else to do. But the classes I'm really looking forward to are the anat and phys classes. The other stuff is cool, but I don't have the intense interest like I thought, and that will harm me. Math, on the other hand (my new intended major), I've found that I definitely have a passion for. It's the weirdest thing.
So anyway, there are only four more classes in biology that I want to take that I'll really work for, but I have enough credits to make biology be my minor. At the same time, there are enough economics classes that I want to take to have economics be my minor. So what makes the most sense is to be a double minor.
Standby for details.

Health Care Reform and Closed-Mindedness
Most nearly everyone (including myself) are biased towards information in terms of political party.
This sounds so obvious (because it is) but it goes deeper than I thought.
We've all heard of the new health care reform thingie that's going through the senate right now. I've been curious about it, because I don't know much about it, and I know it would have huge consequences on many aspects of our country. So I've talked to a couple of people and read one or two articles, and all the information I've found has been given to me through the filter of bias, opinion, and past experience. I don't want this kind of information. I want pure facts, and in addition to that, I would like opinions from people on both sides of the issue. So I looked up the official website that is promoting the reform, and I looked up the text of the actual bill itself.
While I was looking over both of these, I found that I was viewing the information on the website that is promoting the reform in a negative light, already doubting the effectiveness of the reform, and the motives of Obama and his peoples. But then I tried looking at it in a different way, just for kicks. What if this is actually good? What do the people who I talk to know? What should it matter that they are democrats?
Here's some opinion for you:
In my opinion, I think that the majority of the people who talk about this reform know almost no facts. I think that the majority form their opinions from what they see on the news, what they hear from other people, and which party is promoting it. I think that a small amount of people have done some research, but that this research has been clouded by either positive thoughts or negative thoughts, depending on their political affiliation. I think that more democrats support this reform just because it is from Obama or because they are defending their party so they "have to" go with it (like loyalty to a sports team that you were raised with, even though they may suck); and I think that republicans have a problem with it because it's from Obama and because the democrats are supporting it. I think that the democrats look at the good that the reform will do, and ignore the harmful effects, and that the republicans look at the bad effects that the reform will have and downplay the good or pass it off as "fluffy democratic do-good-to-all irrational, wishful thinking".
I think that if people want to have a strong opinion on anything, and argue for or against something, they should do the research for themselves. I think that people should be smart. It annoys me when people strongly argue for or against something without having their facts founded on something solid. It annoys me when people are closed-minded, inflexible, and unwilling to admit that they may be wrong. And it very much annoys me that most of our political crap is all about pushing the names of the parties and the generalizations and stereotypes that go with them, rather than the actual, technical things that the parties are trying to do. Those who really understand what's going on and THEN formulate a strong opinion, and it's valid, are people I respect.
Sure, it's fine to say stuff, as long as you're willing to take in new information.
I suppose what I'm trying to say is: be open-minded, if you don't really know what you're talking about. You can't learn anything if you form a premature opinion on something, and won't accept any other information that contradicts your opinion.
That's just stupid.
But that's just my opinion.

'Cause no one really cares, they're just pretending.
I bought one in the bookstore today.
I am set for next semester.
I am stoked.
Christmas break: piano, gym, library, job, get ahead on homework.
It'll be perfect.
I've realised that my life operates on Le Chatlier's principle. It's so very "I told you so", it makes me laugh. Ironically. Cynically. But I laugh nonetheless.

Questions.
On Small Businesses
We just published a story by Elizabeth Olson that takes a look at the Great Cupcake Rush of ‘09, an almost inexplicable spread of cupcakeries around the country. As Ms. Olson reports, a handful of chains — Magnolia Bakery in New York, Sprinkles Cupcakes in Beverly Hills — seem to be thriving but for many others it’s a struggle.
Porche Lovely, for example, opened Lovely Confections Bakery in a gentrifying district of Denver. Ms. Olson writes:
For each cupcake she sells, Ms. Lovely figures she spends 60 cents on ingredients, 57 cents on mortgage payments and utilities, 48 cents on labor, 18 cents on packaging and merchant fees, 16 cents on loan repayment, 24 cents for marketing, 18 cents for miscellaneous expenses and 4 cents for insurance. That totals $2.45, leaving a potential profit of 55 cents on each $3 cupcake.
So far, that profit margin is theoretical because Ms. Lovely is still paying off her start-up costs. She’s reluctant to predict when she may become profitable in part because of the economy — but also because cupcake competitors have been opening in her neighborhood.
What is it that makes this business so attractive to would-be owners? What chances do they have of succeeding?
I liked comment number 5:
When I saw estimated costs per unit in the original article my instantaneous reaction was that there was no way that Ms. Lovely will succeed in the marketplace. Breaking down the numbers reveals shocking poor cost control, take for instance that she estimated that it cost her 48 cents per cupcake. Lets assume that she is paying her employees $15 an hour, at 48 cents per unit each employee is responsible for roughly 30 cupcakes an hour! Either she is overstaffed, overpaying or underselling. There is no way that her current business model will succeed, plus how big is the market for $3 cupcakes? It seems like people get into this business out of some sense of comfort and reconnection, undoubtedly they fondly remember baking cupcakes with there family and want those senses to translate to there business ventures.
— RyanAlso number 9 and 10:
Yet another fad. In a few years, when there are cupcake bakeries everywhere and some mega-franchise, they will have the same fate as all the Curves gym locations around here: boarded up.
— JenofNJAs someone who bakes, it takes more time to make a cupcake than it does to bake a double layer cake- don't kid yourselves, it also has to do with our sugar addiction - we're paying more for someone else giving us portion control, like those little 100 calorie snacks - about one of the worst ways to eat green around.....as for a business model -- there are some who will always thrive because they can spot future trends and some will die out....the darwinian cupcake model-Laura GreenbergI've wondered about this kind of thing too: how the heck do small businesses stay in business with the low profit margin? I remember that the people I was sitting next to mentioned Walmart, and how they didn't make money from the price of the items that they sold, but from the amount of items that they sold. I've also had a friend tell me that because Walmart is so large (or something like that), they buy things in large quantities, and when you buy things in large quantities, they're cheaper. Also, everyone wants to sell to Walmart, because Walmart sells to everyone, and if Walmart doesn't like the price that the seller is offering, they are more able to negotiate it lower, since the seller would make a lot of money from Walmart either way, and if the seller went to a smaller business, they would make less money.
Isn't that interesting? I can't wait until I get to learn about this stuff.
On a side note, I dissected the turkey today. I found a major artery that extended down its spine, I found its spinal cord, I found what I think is either the pulmonary artery or the aorta, I found its scapulas (they're weirdly shaped), I found a tendon that moved the wing. I scraped off nearly all of the meat and fat and tendons and ligaments, and I cut into a few of the bones with a saw. I even boiled the bones to try and get everything off of them. Nobody was near as excited as I was; in fact, everyone but dad was grossed out. Lamesauces. It was cool. It was really cool. I learned about bird and human anatomy.
Happy Thanksgiving! I'm going to go read more stuff.

More interesting stuff
Description
Have you ever been upstairs, wanted something that is downstairs, gone downstairs and then forgotten what you wanted. In fact it is only when you go back upstairs again that you remember what it was that you wanted.
When you store something in memory, the memory is not just of the item being stored but also of the context in which the memory occurred. Recall and recognition thus may be triggered by elements of the context being present.
Discussion
Tulving (1982, 1983) linked storage, recall and recognition by the principle that context is a unifying factor. In his words:
The probability of successful retrieval of the target item is a montonically increasing function of informational overlap between the information present at retrieval and the information stored in memory.
Isn't that just cool?
Something Interesting
The Emotional Mechanism that Biases Decision Making is Distinct from the Emotional Mechanism that Improves Memory
The previous discussion leads to the question of whether the mechanism by which emotion improves memory is the same as, or different from, the mechanism through which emotion biases decisions. The amygdala has been found to be necessary for emotions to improve memory (Cahill et al., 1995). Our own work has also shown that the amygdala is important in the creation of biases and in decision making (Bechara et al., 1999a). This suggests that in the amygdala, the mechanisms through which emotion modulates memory and decision making may be inseparable. The remaining question is whether these mechanisms might be separable in the VM cortex. In order to answer this last question, we tested 12 normal control subjects and six VM patients with anterior lesions that spared the basal forebrain for their memory of a series of neutral and emotionally charged pictures. The series of pictures involved four sets, with four pictures in each set. Each set of four pictures contained two neutral (e.g. farm scenes)and two emotional (e.g. raped and mutilated bodies') pictures. The pictures in set 1 were presented once each; those in set 2 were presented twice each; in set 3, four times each; and in set 4, eight times each. Five minutes after viewing all the pictures, subjects were tested for their recall of each picture they saw, and for the overall content of the picture. The recall of picture content was calculated for each subject as a function of repetition times and emotional content.
As might be expected, both normal controls and VM patients showed improved memory as a result of repetition. The most important finding, however, was that both groups showed a response to the emotion manipulation, producing a better memory curve for pictures with emotional content than for neutral pictures (Fig. 8). Thus, this experiment actually separated the memory curve that is a function of repetition from the curve that is a function of emotional content. The results indicate that the VM patients are able to use emotional content in order to enhance their memory, suggesting that the mechanism through which emotion modulates decision making is different from that through which emotion modulates memory. These results also support the conclusion that the decision-making impairment of VM patients cannot be explained by a deficit in the recall of emotional events.
