fandomhigh | Mathematics: All Classes: Friday 20.1.6: 1. period

Charlie is busy looking over his notes of locker 327. Today would be a good day to volunteer for locker exploration on Saturday. He's sitting by his desk, which is in the front of the room, and the first thing you see when you enter (well, that, and the multiple blackboards and whiteboards). The table of foodness - which today contains danishes, coffee, juice, milk and cereals - is placed on Charlie's left, underneath a blackboard.

The desks are grouped according to classes. There's a group of six tables and chairs for the Beginners, a group of five for the Intermediates and a triangle for the Advanced group. In the back of the room are six computer terminals.

ooc: I realised it would help if the students knew what the room looked like as well...

Advanced:
"Read the chapter on Dimensions and pick a mathematical one to tell me about."

Intermediates:
"Please read the chapter on Numerical weather prediction, and then calculate today's wind chill."

Beginners:
"Look at this list of Mathematical jargons and pick one or two to define for the rest of the class."

Cameron signs in.

Chloe signs in, glancing at Charlie's notes. "What's that you're working on?" she asks.

Charlie looks up and smiles. "My notes on locker 327. I intend to do a more thorough investigation tomorrow. Would you like to join me? For extra credits," he adds.

"Are you sure you want to investigate the locker? I mean, not that I'm not curious about what's in there, but Zero like, disappeared for days when she went in there. ~~You're too hot to disappear!~~ Not that the extra credit wouldn't be nice."

"Of course I am! It's fascinating!" Charlie went on for a couple of minutes about locker 327, eyes sparkling.

If nothing else, Chloe certainly had to admit that Charlie's enthusiasm was contagious. "Well, I guess I never can resist a good dangerous mission. Count me in."

Charlie beamed. "I start around ten, but you can join me whenever you wake up!"

John signs in and raids the breakfast table.

Angela signs in and grabs some cranberry juice.

Signs in. And woot, danishes!

Pip signs in.

Victor signs in, looking slightly pleased.

Walter signs in and tries to restrain himself from grabbing most of the food set out.

Molly signed in. She looked like she had actually gotten a full night's sleep and was alert all through class.

Broots signed in and helped himself to real food.

Pippi misses the class.

"Look at this list of Mathematical jargons (http://en.wikipedia.org/wiki/Mathematical_jargon) and pick one or two to define for the rest of the class."

"I'm going to explain handwaving and rigour, because both terms are so related to each other. When the term rigour is used in maths, it's meant to imply that a theory has proved to be sound. Most of the time thanks to the use of axiomas. It does happen that in a theory some details that are of minor importance don't get researched into detail or proven to be mathematically rigorous. In that case we talk about handwaving. The researcher assumes that that particular part of his theory is right, but doesn't bother to actually prove it."

"In logic, there are necessary and sufficient conditions. A necessary condition is one that must be satisfied, for the result to happen. Drinking is necessary to stay alive, but not sufficient; if you drank but did nothing else you would die. A sufficient condition is one that, if it is satisfied, the result is certain to happen. Jumping is sufficient to leave the ground, but not necessary; there are many other ways one can leave the ground instead without doing that."

"The term "if and only if", which is kind of self-explanatory, refers to when one statement is necessary and sufficient for another statement. In other words, if one is true, the other also has to be true.

"Back-of-the-envelope refers to kind of sketchy calculations that are more guesswork than proof, but test or support anyway. Kind of 'rough calculations', I guess."

"I decided to pick two terms that sounds kinda funny, so you can use them with your friends and make them think you're crazy. The first one is arbitrary, which refers to something done without the use of logic. For example, if you, say, duct tape a golf cart to the Principal's ceiling on a whim, that would be arbitrary. In math, pulling a number out of thin air and using it as the base of an argument would be considered arbitrary.

Aliter is Latin for "otherwise" or "by another way". It's basically used to show an alternate way of doing things, like another way to solve a problem."

"Please read the chapter on Numerical weather prediction (http://en.wikipedia.org/wiki/Numerical_weather_prediction), and then calculate today's wind chill (http://www.webmath.com/windchill.html)."

Chloe pulls out some paper and starts calculating, resisting the urge to just say "really darn chilly."

John starts playing with the figures to get a numerical equivalent to "well digger's foot" cold.

Angela reads the chapter and scowls at her paper as she tries to work it out.

She comes up with 26.5 degrees farenheit, based on 40 degree weather and wind speeds of nine miles per hour.

Walter's calculation could be brought down into laymen's terms as "not quite cold enough for a coat."

"Read the chapter on Dimensions (http://en.wikipedia.org/wiki/Dimensions) and pick a mathematical one to tell me about."

"The inductive dimension of a topological space may refer to the small inductive dimension or the large inductive dimension, and is based on the analogy that n+1-dimensional balls have n dimensional boundaries, permitting an inductive definition based on the dimension of the boundaries of open sets."

Charlie is thinking very hard about how to get accurate data about the inside of the locker.

"Mr. Eppes? The roll for the last class." Broots handed Charlie a sheet of paper. "Beginning and Intermediate were at 100%, but um, in Advanced? Only I kinda showed up. I think Jessica left school though, so that makes just Susan a missed class. Um, wouldyoulikesomehelpwiththelocker?"

Charlie beamed. "Thank you." He put the paper in his attendance file. "And certainly! I start at ten, but I'll be working all day!"

Just in case.
