Mathematics: All Classes: Wednesday 09.11.05 (08:00-10:00)

Charlie's much more bouncy today than he was on Friday. "Today's messages:

Wallace Fennel, you have detention on Saturday, unless you can give me a valid excuse for missing both classes last week."

Beginners

[charlieeppes.livejournal.com]

Charlie gives them all an apple, keeping two for himself. "Last time we talked about numeral systems. Today I thought we'd look at the basic numbers themselves. Please pick one of them following to study. Like last time, you'll be telling the class on Friday about the topic you chose."

Natural numbers (http://en.wikipedia.org/wiki/Natural_number)
Prime numbers (http://en.wikipedia.org/wiki/Prime_numbers)
Integer (http://en.wikipedia.org/wiki/Integer)
Decimals (http://en.wikipedia.org/wiki/Decimal)
Rational number (http://en.wikipedia.org/wiki/Rational_number)

((reserved to the shy creature in the back: Imaginary numbers (http://en.wikipedia.org/wiki/Imaginary_numbers)))

"I thought students were supposed to give their teachers apples, not the other way around." Chloe smirks and takes the apple, looking over the list. "I'll do prime numbers."

"I'll take natural numbers. That sounds easyish." Faith takes an apple. "Thanks."

"Apples! I love apples!" Barbossa took a big bite. "One of life's greatest pleasures, t'be sure." He looked at the list. "I be pleased t'learn about integers," he offered.

Re: Beginners

Maia smiled shyly and took an apple. "Thank you sir" She said looking over the list of numbers to debate about until Friday.

Maia turns and pats her "Do you like apples little Carmen?" Maia rolled her eyes feeling like a total dork.

Intermediate

[charlieeppes.livejournal.com]

The students are given a sheet of paper with the following on:

1. When I'm shooting at something, I'm unconsciously using math to aim

2. A unconscious use would be singin' either with or without accompaniment, keepin' yerself on key and at th' right speed fer th' song.

3. It's not fancy math, but I have to roughly calculate the odds of me getting a good shot at the goal or breaking through the defense depending on how many players are in my way

4. unconsciously when figuring out how hard to hit something or someone

5. Unconsciously, I'm goin' with snooker. You have to work out angles roughly to make a good shot.

6. Well, I always have to remember the exact widths of bits, and stuff, when doing repair work, so I guess that's sorta-math. And I gotta make sure all the parts rotate or move at the right rates, too.


"These are all examples you gave me for unconscious use of math. Today I'd like you all to pick one or more examples and set them up as math problems. You can either use unknowns or make up a number problem."

Breaking Jack's jaw with your fist requires twice the amount of force than breaking Hathor's Lucy's jaw with your fist. Breaking T's jaw with your fist requires four times the amount of force than breaking Jack's jaw. Work out how much force is needed to break T's jaw with respect to how much force it takes to break Lucy's jaw.

Advanced

"Well." Charlie looks at the students. "There's just three of you left, so you all have to work together on this project. You didn't work out a project last time, so I have some suggestions. Please open your books on the Computer Science (http://en.wikipedia.org/wiki/Computer_science) and turn to Computation (http://en.wikipedia.org/wiki/Computation)."

He reads aloud: "The theory of computation studies these models of general computation, along with the limits of computing: Which problems are (provably) unsolvable by a computer? (See the halting problem and the Post correspondence problem.) Which problems are solvable by a computer, but require such an enormously long time to compute that the solution is impractical? (See Presburger arithmetic.) Can it be harder to solve a problem than to check a given solution? (See complexity classes P and NP)."

"Looking into these problems and writing up a report about it, would be a good project. Alternately, you can look through the book and see if there's something else that strikes your fancy. This is practical application, so if you'd rather work on algorithms or create programs, that would be more than acceptable. For additional advice on the execution of your project, I hope to be able to set up a time for you with Dr. Carter."

"Programs?" Broots visibly perks up.

(OOC: Ah hell. Please tell me I didn't misread the class info and that Math is chronofluid [even with you posting class times], or else Murphy's going to be in trouble, as he's in Classic I from 8-9:30 on Wed.)
