I’m reposting this from the random thread:
“Does anyone know how to explain the difference between electric potential energy and potential difference? I know that electric potential energy is basically energy due to position–at least that’s how I understand it–and the potential energy changes depending on the distance between charges. Potential energy is measured in volts, and is the change in electric potential when a charge is moved in a field (work done to move/charge). I don’t know. I’m just confuzzled. -headdesk-”
Also–who else is taking APs this year? These next few weeks are going to be insane. This week I have more standardized testing for the school (PSSA science!), then the SAT on Saturday, AP Spanish next Wednesday, AP US History on Friday, and AP English the following Wednesday. I think the only way I’m getting through them is imagining how easy life will be once they are all over.
My teachers apparently decided to load me with homework on my birthday.
first post?
okay, so how dead am I if my math binder, my notes and my homework for tommorow have dissapeared in the tech theatre workshop, likely under a cubic food to sawdust and metal shards?
also, if they don’t let people in when it is not tech time or during school, which got out four and a half hours ago?
And thirdly, if I am not even positive it is in there ?
3 – Really dead.
Does anybody understand mathematical induction? I know that I have to :
a) prove true for n=1
b) write the statement for n=k
c) write the statement for n=k+1
d) assume true for n=k, use algebra to change the statement in b) to the statement in c)
e) make a conclusion
My problem is in the fourth step. I know I need to add k+1, but I’m not sure what to do with the current k or how to modify the statement for adding k+1. HELP!!
Hm. I dunno if anyone will see this in time, but:
What is a *specific* example of a famous situation where someone suffered the consequences of being misunderstood because no one “walked around in his/her skin?”
I can’t think of any situations. But they must exist! I know they do.
Well, I homeschooled, so not much for me… sorry to gloat!
That’s so cool! I always thought it would be cool to be homeschooled…
if you thought I was gloating.
Weird, I got a message saying that I was posting too quickly. I was doing that just to add the postscript to the other comment, if that makes any sense.
My English and Government teachers (they work together) are piling on SO. MUCH. [-snip- Language, my dear!]. HOMEWORK.
Two worksheets in English, a worksheet and a seminar in Government, a paper in English, and an exam in Government that *requires* preparation.
>.<
That’s horrible. They’re conspiring against you, definitely. I guess you usually don’t study for test? Me too. I’m a sponge.
Good luck on your exam!
I typically don’t study, yes.
Whew! The government exam is done. 100%. Ah well, ’twasn’t that hard anyway.
Oh, sorry, GAPAs.
Uggh. We’ve got exams in a week and SO much homework- I never study but you’d think they’d give some time for less… absorbent people. THREE HUMANITIES ESSAYS (on the Middle Ages and William the Conquerer) TWO SCIENCE WORKSHEETS (on E=mc2) A POSTER AND POWERPOINT IN ENGLISH (on Charlotte Doyle) A POWERPOINT IN ART (on printing) A 3D MODEL OF A HOUSE IN DESIGN TECH, AND AND SOME SORT OF EVALUATION (I’m not sure exactly what) IN MATHS! And in between that we’re supposed to spend time afterschool helping to clean up the Science Lab (some vandals came in over the weekend, smashed a lot of test tubes and beakers, messed up equipment, and spilled hydrogen peroxide and some sort of paint thinner all over the floor.
Someone told me that 6th grade was relaxing, but were they ever wrong. All that is due before exams. And no, I haven’t been procrastinating. We were only told most of that yesterday.
I’ve also got to prepare for this test to see if I can skip a grade, which I AM studying for, because I really want to escape from my classmates, all of whom seem to eat a mixture of sugar and “essence of sheer stupidity and tediousness” for breakfast.
Does anyone know what the half-life of Barium-143 is?
You’re probably wondering why I’m blogging instead of working. Well, I’ve finished most of my work and I’m taking a break because I fell asleep into a plate of cheese while reading a book on Physics for my grade-skipping test. I’m supposed to have a “variety of knowledge in all subjects” and be able to “answer questions about real-life scenarios in the following…”
I do get to skip a double Humanities and Science review periods to do the grade-skipping test though, so a bit of luck…
Sorry that sounded as if I was bragging. I wasn’t.
Ooh, it’s so nice to know I’m not the only one who doesn’t like their class. Unfortunately, I have no chance of skipping, not that it would do me much good (small school), because my school doesn’t do that.
I finished writing a research paper on Robert Frost! Why on Earth do we need research papers? So we can learn to parrot? Why can’t we come up with our own stuff?
I know they’re good and all, it’s just bothersome.
Schools have to do it. My mother bullied the school board at my school into letting me take AP and skipp, but they aren’t being helpfull. I have to study myself, and fill in the blanks myself. Next year, I have to pass all my classes, otherwise I’ll have to go back. As for bullying the school board- if you get your I.Q. tested and score over 130, then the schools here have to give advanced programms. That’s how I did it. Good luck, kokopelli52, and don’t worry: compact, compact, compact !
Hmm- Thanks for the luck. But our school doesn’t do IQ tests. My mother was on the PTA board in New Zealand so I got advanced classes and GATE during Elementary school. But in Singapore they aren’t biased like that. And they postponed the test (thank god). The examiner was seriously ill. I watched her throw up.
We had to do this research paper in Physics (Isaac Newton) and everyone wrote exactly the same thing. Not just the facts- I mean the opinions. And everyone cited the same one website in their references. If we aren’t encouraged to write what we think, young, easily moulded people such as ourselves will become nothing more than robots, programmed by an amateur computer engineer to repeat what others say! (sorry for being metaphorical). And in English, we had to do a poster on Shakespeare and if we didn’t include a certain critic’s comments on Hamlet and just included our own our marks were lowered! Who cares what other people think??
I just found proof that blogging comes in handy: I have to make an E-portfolio, and part of it is creating your own little blog (monlogue, describing your learning process). I happily chattered away to myself, stopping only occasionally to remember that it was supposed to be topic-related and the principal might read it. Two posts per month are the min, and I came up with 5 per hour spent online, making it look like I put in a lot of work when I’ve only logged in once or twice.
My studying for math yesterday was cut abruptly short when I realized that
a) I’d forgotten my math stuff
b) It was a beautiful, sunny day
c) There was an old bike on the attic that I could use
d) The water outside is warm enough to swim in
I doubt that I did well on the test, but hey, I had a great time
Now I just need to write 200 W for German- A workaholic with a pneumatic drill outside my window who’s been at it for 5 1/2 hours is driving me bonkers. *headdesk, headdesk*
Go German! German buddies, disperse!
(inside joke)
But seriously, how fluent are you at German? I’m only in my second year, so I’m not very good at it yet. I’m going to have to memorize a speech about myself for my final!
I’m bilangual… *declares self official german-(and french)-homework helper*
OK. I seriously need help with this:
I need at least 8 prominent to semi-prominent pro-life groups that existed in the 90s and whether or not they were religious-associated. I got the 8 pro-choice ones already from a feminist book that my mom found in our basement, but all the internet websites just have huge long lists and the one that I did find that was shorter didn’t even have Operation Rescue on it, so I didn’t think that it was anything good.
So, GAPAs??? P*ease?
Sorry, I can’t help. Most organization names sound alike to me and don’t stick in my mind. I wouldn’t have remembered Operation Rescue if you hadn’t mentioned it and would have to do the same research you would to track down others. Maybe a more useful GAPA will come along.
Thanks for trying to answer my question! I’ll probably try to check out a book from the library tomorrow (it’s closed on Mondays).
If anyone else wants to help, I’d appreciate it!
Here’s a couple I found in my bioethics “textbook”. You’ll have to do some research on your own to try and determine if they’re religious affiliated or not–I’m afraid I don’t have time to look…. *apologies*
Operation Rescue
Rescue America
Missionaries to the Unborn
Planned Parenthood
I hope that helps you out a bit!
gah. *is annoyed* My post has vanished……whatever, here’s the short version:
operation rescue
rescue america
missionaries for the unborn
planned parenthood
if my post vanishes again I am going to break something…..
Your comments were sucked up by the spam vac.
How very odd….I didn’t even have a single emoticon. *accusingly* Has Kokopelli been messing around with the spam vac again?
Thanks, Luna! I basically needed some bigger ones because I can surely find some smaller ones online. Now I just have to find a reliable place with all of those in it… (because I have to use endnotes)
I’m sorry I’m posting again so soon (am I abusing the system?) but I seriously need help on something totally unrelated.
I’m taking Health/Wellness II online this year. There is this one assignment that I skipped and worked halfway into the next unit before coming back to. I have to finish it before I can unlock the unit test.
It’s about TV relationships. The assignment is to assign positive and negative relationship traits to each character in the show (not relationship–weird, I know). I have to do this for at least 3 primetime comedy or drama shows that I watch. The problem: I only watch one show.
This is where the fabulous MuseBlog comes in.
It’s not that hard, you just have to assign one of these good relationship traits and one of the bad traits (which are the lack of the good traits–very creative on my teacher’s part) to each major character and why they have the trait and are lacking in the other trait. I did it in about 10 minutes for The Office.
Here are the traits:
Trust
Honesty
Respect
Cooperation
Compromise
Acceptance
Dependability
Loyalty
Empathy
I wouldn’t be asking you guys on something as big as this if I didn’t think it was totally unfair that the teacher assumes that every student of his watches at least three primetime comedy or drama shows a week. I’m not a TV addict; I’m an internet addict.
I will owe give anyone who helps me on this 900,000 kilos of virtual chokolit.
Or you could do MB, and give us a made up name.
16- Hmm. Sorry. I don’t have a TV.
That is unfair!
What does a potassium atom look like? I have to memorize the periodic table- which isn’t too hard- but I also have to be able to draw a lot of the atoms.
Potassium… *fetches periodic table* Nucleus: 19 protons, 20 neutrons. 19 electrons. Electron cloud makeup: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1. Simpler terms: Two electrons in first electron level, 8 in the 2nd, 8 in the third, 1 in the fourth.
I never really understood electron cloud theory. I mean, I sort of understand that there’s different shapes of orbitals (s,p,d,f) but I don’t get how they orbit around the nucleus… that’s why I like thinking of atoms the way scientists did before electron cloud theory existed with the electrons orbiting in simple rings.
17.1- Thanks!
OK, this is a lot simpler this time!
I need a reliable source that says that “Song X” by Neil Young is about the murder of David Gunn. I sort of found it on Wikipedia and it makes sense, but I’m not allowed to use Wikipedia as a source. Thanks in advance if you help!
My last request for help was kinda long, sorry about that. I was desperate. I have all that I need now.
Wikipedia usually has its own links to sources at the bottom of each page. If not, there isn’t much evidence you can use to determine creative intention. The whole point of writing a song is about leaving something to interpretation.
I. hate. Powerpoint.
I’m supposed to make a presentation about computers in navigation- it’s tomorrow, and the principal will be grading me, which
a) scares me and
b) prevents me from making jokes (navigation is the art of getting from a to b without being smashed to bits on point c, e.t.c…), though I think I won’t be able to help myself in some cases, especially if they involve ships going sailing on land and the difference of making a right turn on the atlantic ocean as opposed to on a street which continues to the left.
I’m very nervous, and I still need to write the stupid thing, and I’m overly critical of my work, and my best source is my dad (I couldn’t find much on the internet).
*screams and goes away (still screaming, until she hits the (charted) ocean and sinks because she is not a boat, and she is also not funny and knows it, but very, very nervous and she always talks to much when she is nervous*
What is the big deal meant to be about The Outsiders? To me it just seemed poorly written and violent. I mean, yes there’s a theme of belonging and all that but still… Nobody’s going to read this for a while, but please answer me if you do.
I liked it, but I don’t really remember what happened because I read it four years ago…
*agrees* I thought it was kinda boring. Yeah, the nicest person dies, but they deliver a sentimental message. *enjoys literary pessismism*
Could someone please help me with vectors? In a physics lab that’s due tomorrow, we had to analyze a video of a boat going on a river in various directions. First, they showed little floats going down the river to get the speed of the current. Then the boat went upstream, downstream, was pointed straight across (but was carried by the current downstream), and finally went straight across (and so was pointed upstream). The software we used gave us the coordinates of the tip of the boat at each frame of the video, and gave us the magnitude of the resulting vector. We’re supposed to figure out the (supposedly constant) speed of the boat were it in still water, calculated for each example and then an overall average. But I can’t figure out how to find the original vector if all I have is one vector (the river current) and the resulting magnitude (the video of the boat). Could someone please help me, if any of that made sense?
River current: 5.574
Upstream: 2.647
Downstream: 6.399
Now, as I’m seeing it, the speed of the boat in still water would be equal to the “downstream” speed minus the current, right? But that yields a completely different answer than the current plus the “upstream” speed, which I believe should be the same thing. What am I doing wrong here?
Eh, forget it. I just realized I must’ve taken the measurements wrong. Hypotenuses can’t be the shortest side of a triangle, which rather disagrees with my other data.
*head spins* *collapses*
My evil Global History teacher (Fishy has her as well) assigned a thematic essay. Due Monday. That graphic organizer alone took me THREE HOURS. So I am escaping for a few minutes…
I hate History.
Oh, and does anyone know if there are civilizations that did not start up around rivers?
What did you end up doing? *still has no idea what he’ll be doing*
I don’t think any of the major Western Hemisphere civilizations started around rivers.
Define “civilization”.
Alright, thanks! That may be useful knowledge…
Fishy- I’m writing about Mesopotamia and Ancient Egypt and how they were influenced by their rivers. I have the feeling that I’m doing the whole thing wrong, but I don’t know how to fix it anyway…
Must. Finish. Lastparagraph. *groan* I can never do conclusions…
And then I have English homework. Joy.
Have any of the older Musers here read The Handmaid’s Tale? I have to write an extended metaphor essay about the book (comparing the book to something else), and I’m having extreme difficulties coming up with any ideas.
Comparison with modern monotheistic religions? Maybe Islam’s treatment of women?
Fio: By “something else,” do you mean another book? How about 1984? Or Brave New World? They’re all examples of dystopian fiction.
On the assignment sheet, my teacher ‘helpfully’ listed some examples:
“Wuthering Heights is very much like the soap opera ‘All My Children'”.
“Victor Frankenstein is like an overacheiving Honors Student who gets buried by his workload.”
And my favorite: “The memorable characters of Pride and Prejudice are like fresh brewed cups of coffee: warm, rich, and ‘good to the last drop.'”
The assignment also says “You should be able to do even better in coming up with comparisons that are even more unusual.” Therein lies my problem. FS’s comment did give me an idea (I could compare the book to the situation in Iran), I still would appreciate other ideas.
Fio: Oh, I see. Your teacher wants something more like this:
“Reading The Handmaid’s Tale is like having someone slap you in the face with a codfish: The message is clear, but the delivery is heavy-handed, and it leaves you wondering whether the lesson was worth learning.”
Is that the general idea?
=D =D Yeah, something like that. I might just use that example (if I can get the book back from my friend and find some ways to support that claim).
Oh, Robert, if only you taught at my school!
I got a 100 on this essay. And the teacher says she wants to keep it as an exemplar for later classes. I’ll post it up her later tonight.
Up here.
I have to write a summative (big huge essay with pictures) for history. I’m (basically) supposed to compare the causes of the American Revolution to a modern day issue that could possibly cause a similar civil disturbance. I’m writing mine on the Patriot Act. I still haven’t finished outlining, so writing this one will be hard, and I think my paper will be 10 paragraphs long. (That is, 10 speller73-style, page-long paragraphs.) In other words, I’m dying.
Speller: One problem you’ll have is that the Patriot Act clearly did not cause a revolution. Instead the country had another election, in which the Patriot Act wasn’t even a major issue.
It needs to be a potential revolutionary incitement. Might I suggest personality-driven news hosts like Bill O’Reilly or Rush Limbaugh? They’ve already incited murder (the Tiller case), it wouldn’t be a stretch of the imagination to consider revolution. You can even compare it to the climate around the Oklahoma City Bombing.
We were supposed to find a contemporary issue that had similarities to the causes of the Revolution. It was supposed to be an issue that could, based on a manual we read, could hypothetically cause a revolution (regardless of whether it did or not).
And did you write about the Patriot Act?
Yes. (It’s due Wednesday actually, so I’m not done.) My exact thesis was:
The Rand Corporation’s assertion that a lack of independence and justice causes civil disturbances is an accurate explanation for the American Revolution; because of similar factors, the USA PATRIOT Act could cause a civil disturbance.
I ran it by my history teacher and he liked it, so I figured I’d go with it.
Agh, Bio emergency. Tesseract helped me with this one earlier, but the last question is stumping me….
“In addition, a good experiment must have replicates, be able to be repeated, and have a minimum number of assumptions. Write a paragraph that uses information from the experiment to explain how the vermiculturist took care of the above three requirements.”
The problem is that en DIDN’T, at least I don’t think so. My question: what would my teacher or whoever wrote this piece of torture have meant by “replicates,” “be able to be repeated,” and “have a minimum number of assumptions”?
In order for an experiment’s results to be accurate, each run through the experiment must be repeated multiple times to ensure accuracy and precision.
Exactly. En didn’t do that.
Okay, this is what I have so far:
The experiment has replicates, because each trial was done over a period of a week (or in the control’s case, a month) and then the results for every 24 hours were averaged. If you knew enough about worms, you could possibly be able to repeat the experiment, because the experimenter did give some detail—such as the exact percentages of moisture and sand and amount of food given per square foot—but there were a lot of things which would have been important to repeating the lab which he or she didn’t say. For example, nowhere was it recorded how the moisture and sand were spread out throughout the container, what type of container it was, how the soil was covered, what kind of light it was kept in, whether it was exposed to the elements, whether the moisture was ever replenished or just left to evaporate, exactly how long certain periods of time were, what type of food was given, how it was spread out, and how many worms there were.
They’re trying to keep it simple for (I’m assuming…) first-year biology experiments. A real journal article would have covered all of the stuff you mentioned. You should probably just mention the things that the researcher did specify.
Need-to-finish-essay-before-tomorrow-morning-200-words-left-gasp-help-what-do-you-think-hero-means-help!
HALP!
What do we think “hero” means? Well, to start with, do you have any heroes? If so, what makes them heroic in your eyes?
*is up early* Yes, I’ve already done that, I just need filler.
Hm. I’m not big on filler. You could talk about how the types of people regarded as heroes have changed over time. At various points in history (including American history), people have granted heroic status to soldiers and generals; nowadays we tend to idolize people who can sing and dance. Or you could note how newspapers and TV often apply the word “heroes” to people who have survived natural disasters such as hurricanes or who are living with disabilities or undergoing treatment for diseases such as AIDS or cancer — people who once would have been regarded as “victims.” It may be admirable to behave well in adversity, but is it heroic? The Greeks and Romans wouldn’t have thought so. Or you could talk about two kinds of heroes: those who inspire you to be more like them,or at least make you hope that you would be like them in certain situations, and those whose abilities are so far beyond yours (such as champion athletes) that you know you’ll never be very much like them and can only watch them with admiration and awe.
There’s a lot one could say about heroes.
For that matter, why are champion athletes given automatic hero status, whereas exceptionally skilled individuals in most other fields are not?
Because the US is obsessed with competition, machismo and achievements that don’t necessarily require much intelligence?
Whereas the rest of the world ignores athletes and glorifies dentists and accountants.
The rest of the world (shockingly) follows the example set by the US. However, in countries like Britain, Germany, Switzerland and France, athletes have far lower hero-value than they do in the US. Swiss tabloids spend more time praising the heroes at CERN than it does its hockey players. Italy is obsessed with “calcio”, but Italy is an anomaly.
I think the phenomenon predates the U.S. by a few millennia. Perhaps my question should have been why does that status endure? It’s easy to see how athletes would be revered in a culture in which hunting and hand-to-hand warfare are a way of life, less obvious when the direct correlation no longer applies. Is it simply persistence of habit migrating to other cultures? Lots of interesting questions, though probably traveling outside the scope of JW’s essay.
…which he has probably finished by now.
Indeed. Now, on to essay Number Two!
Did you define heroism? That alone has had entire books written about it.
29.1.1.1.1.1.1- I should really move to Switzerland.
Now, back to homework.
A question: book burning is legal, right? I need to know for a Spanish project.
People do it, so I’m assuming it is…..Yeah, bad logic on my part, I know, but…. *shrug*
I need to write a (relatively hard, competition-type) math problem for Friday. I’m thinking combinatorics, maybe something with generating functions, but I don’t have any inspiration.
Also, does anyone know what a radius of convergence is? There’s a question about one on my problem set for math.
An urgent physics question: is friction directly proportional to surface area? My physics lab partner and I can’t figure that out. If µ were based on the amount of contact between two surfaces, then friction is directly proportional to surface area. I think. If µ isn’t, then friction isn’t. Could someone please help?
Eh, forget that.
What is the French festival la victoire?
I have no idea what it is, but it sounds like they’re celebrating a victory. Can you elaborate?
Not really. *sigh* We have to research various French festivals, and when I Google this one I get… shoe websites. Hopefully we won’t have to know all of them for our test (and there’s certainly a lot). *crosses fingers**uncrosses fingers so can type*
Why is it that every time I start to do homework, I find myself on MB?
I’m supposed to be studying for my big latin exam, correcting my french exam and writing a 600 word essay in my favorite language with its wonderfully transparent spelling (German) on Nathan the wise (the/a play) and the Aufklärung (you know, renaissance “I’m sick of doing what the church says). Yay me. Okay, fine, I’ll get offline and start working.
I’m posting here and on the random thread:
How did geographical features affect ancient China’s history (social, economical, political, religious…)? I already have the isolation and fertile land because of the rivers, but I have a feeling that I need more. I forgot to get a packet -_- .
Does anyone know the dimensions of Notre Dame Cathedral, the famous one in Paris? I need….
Height of the facade, depth of the facade, and then the dimensions of the rest of the building.
Thanks!
Sorry…..I didn’t take measurements when I was there. XD
Have you tried a Google search?
*headdesk*
I have to do a presentation on Charles Dickens, tomorrow. I haven’t done anything so far and my motivation= 0. I only have to cover an x-mas carol (easy), his life (okay) and hard times (I hate that one).
And what got me into all this trouble? NaNoWriMo!
I’m still conteplating the irony of risking flunking english because I wrote a 50k novel instead of doing homework on the simplified version of brave new world, which FYI only has 32k words. *snort*
I’m dooooomed.
My poor bookgirl_me. It will be ok!! YOU WILL GET THROUGH THIS. And just remember, tomorrow it will be all over.
How does one start off a speech when running for president?
What sort of president? President of a club? President of the United States? Student council president?
“My fellow Americans” seems to be fairly standard when running for President of the United States.
ACK
CRAZY ENGLISH TEACHER CRAZY ENGLISH TEACHER HATES CHILDREN LOVES HOMEWORK WINTER BREAK SOON MISS OLD ENGLISH TEACHER CRAZY ENGLISH TEACHER WHO HAS MERMAID HAIR CRAZY ENGLISH TEACHER HOMEWORK HOMEWORK ON SCRIMA DO NOT WANT TO WRITE POEM ABOUT SCRIMA FELLOW CLASSMATE 2 MORE PARAGRAPHS AAAHHHHH
Seriously, why do teachers seem to feel it necessary to assign us lots of homework the week after winter break? We’re not even ASSIMILATED again yet.
I really need to get off MuseBlog and do my science already.
I don’t know if this should go on the Math thread, but I’m posting it here.
“The legs of a right triangle are consecutive even integers. The perimeter measures 24 cm. Find the length of each leg.”
I’ve attempted it several times. I started with the Pythagorean theorem, but I couldn’t figure out the… I don’t even know how to end that sentence. I just couldn’t do it. I don’t need an answer, just how to do it.
Help?
The legs of the triangle we can label x and y. Since they are consecutive, even integers, we can say that y-x=2.
Using pythagoras, we can say that h=(square root of)y^2+x^2
Using the previous equation (transformed into y=2+x), substitute the y in pythagoras for 2+x.
Hence we have h=(square root of) (2+x)^2 + (2+x)^2
We know that h+y+x=24
Substitute everything you can with the x equivalent to get this:
[(square root of) (2+x)^2 + (2+x)^2] + [2+x] + [x] = 24
And voilà , a single-variable equation. Easiest thing in the world.
At least, that’s how I’d do it.
After looking looking at your explanation for just a bit too long, I got it. The problem was that I didn’t realize that I could substitute “a” and “b” in a^2+b^2=c^2 with “x” and “x+2.” The consecutive, even integers were just floating around in my head, wondering where to go.
Thanks.
Or, guess and check. There are only so many consecutive even integers from zero to twenty-four. And I believe you can stop testing at twelve… Or sixteen or so. Either halfway or maybe two thirds of the way considering it has three sides. But anyway.
Or, know your pythagorean triples, seeing as the given value of the perimeter is an integer. There is only one primitive pythtrip with a sum less than twenty-four – [3, 4, 5]. Looks slightly too small, though- well, double it.
Six eight ten. Add then and you have twenty-four. Done.
-A
Not even that. Even easier, think of the rt. triangle lengths that come out to 24. There’s 6-8-10. Easy. Just memorize the primitive triples.
Sorry, I missed the end of your post.
First paragraph- Guess and check is not appreciated by eighth grade math teachers…. But if I were doing it by myself then I would probably do that.
Second Paragraph- I don’t even want to know what those words mean…
If guess and check isn’t appreciated by eighth grade math teachers, then they’re being unnecessarily difficult and restrictive; it’s a valid strategy a lot of the time. If just for figuring out how you should be doing it that’s not guess and check, but as a standalone strategy, as well.
Which ones? Because I don’t even know what coprime means, technically, though I’m assuming it means they don’t have a common factor (and therefor can’t be reduced).
-A
If I ever, ever decide to do my research for a geography project in german on english wikipedia, (the teachers herself said it’s okay) because it has more details, while listening to music with lyrics, lock me in a padded cell. After a day of translating things like “infant mortality rate” into german while listening to music in one of those languages (it helps me concentrate), my brain is fried. I usually think more in pictures, but when I’m trying to write something I have to put it into words, and I now have a killer headache from trying to think in two languages at once. And I’m not even done yet! *headdesk* This is eating up my weekend… *sigh* When (insult) said I had no life because I study to much- for this weekend, she was right.
Never mind. I’ve found a spanish song.
Instrumental music works well in this situations. When I’m trying to concentrate on work, I usually listen to lute music.
I’m doing science fair research on taste buds, and was wondering if Spicy is considered a taste or not?
No.
So it’s the pain sensors in your tongue reacting to capsaicin, right? ((I’m sure I spelled that right, but spell check doesn’t recognize it. It also doesn’t recognize umami.))
A very specific pain receptor, yes.
Why on earth did you decide to do a project on the tongue? Seems complicated…
You could look at the Wikipedia pages for capsaicin and TRPV1 (the tongue’s capsaicin receptors) for a base to work off for your project.
Try “trigeminal nerve,” too. While that’s not part of the taste buds, that will give you some background for understanding the spicy reactions.
Thanks. I’ve been having trouble finding citation for some of my facts, because the wikipedia page on taste buds incorrectly classifies spicy as a taste.
Try the Wikipedia article on taste.
My GT teacher gave me a huge packet to go with a book. The book is called “Children of the River”. The book is no problem, I could read it in a day. But the packet is due at the end of the month and I can think of lots of other things I would rather be doing. Like going on MB or writing, drawing, climbing trees and then jumping in to the snow (That’s really fun you know!). “sigh”
All right, I need help. Desperately.My assignments due on Monday:
1.Copenhagen Climate Conference Research Paper
2.Human Rights Writing Prompt
3.French Review/Exercises
4.Human Rights Photo Project
1.- This is at the top of the list for a reason. I needs to have 2 to 2 1/2 pages, double spaced 12 point Cambria, arguing for or against if the CCC was successful. I needs to have citation for all information I get, so info from you wouldn’t work, unfortunately. BUT, can you please give your opinion on the CCC?
2. I totally forget what I have to do for this, but it’ll have to stay on tomorrow’s agenda.
3. This should be easy enough.
4. I need a willing volunteer to mime breaking into my room and stealing stuff… and then get arrested somehow.
HOWEVER, I only have half a day or less tomorrow because 1.) I need to get some extra sleep, until 10ish, and 2.) There is an indefinite chance of my roommate and I moving out of our meant-to-be-single room and swapping rooms with the person who is alone in a double upstairs. Now my roommate is being stubborn and for doesn’t want to move because the people upstairs are a bit more annoying than the ones downstairs, the bathroom upstairs is a bit worse than the one downstairs, and he doesn’t want to walk up/down the stairs twice a day (it’s 20 steps!). I don’t see the big deal, he is antisocial and stays in his room on his computer all day anyway, so only the middle reason really applies to him. Grargh. If we do move, it will be my 3rd room switch this year. I hope I have a better rooming situation next year…
Anyway. Sorry about that, I need to rant a bit. Can someone please help with the CCC essay please?
GAPAs?
I have made absolutely no progress. :fustrated:
Blame China for blocking negotiations, and then blame the Senate for making it into an issue of political importance for Obama, restricting him from pursuing the best possible deals for climate change. Monbiot wrote an article in the last Guardian, google around for it.
JW: About Copenhagen:
The assignment is straighforward enough. You have show that you understand what the Copenhagen conference was supposed to achieve, explain what it actually did achieve, and decide whether the achievements were sufficient to be considered a success.
Two-and-a-half pages double-spaced really isn’t much room, but ideally, I’d set it up something like this:
A. Background: What was the situation before Copenhagen (the Kyoto Protocol)? What did the Kyoto treaty say, who decided that it needed to be updated, and on what grounds?
B. Before the conference: What were the main goals of the conference? Who were the main players in the negotiations (the United States, Europe, Japan, China, India, developing countries), and what did each group want to achieve? What were the conflicts among the groups?
C. [There’s definitely not room to get into the negotiations themselves, but remember that leaders from all over the world flew to Denmark and lost a lot of sleep trying to reach an agreement. Clearly they thought something important was at stake.]
D. Results of the conference. What did the leaders end up agreeing to do? What issues weren’t dealt with? (Be specific. The negotiators didn’t go home without any results at all. What did they accomplish?)
E. What next? (Copenhagen isn’t the end of the story. More climate talks are coming up in Mexico City later this year, and still others will follow. Negotiators will have more chances to make agreements. Did Copenhagen pave the way for them, or was it a false start? Could the publicity the conference attracted be considered an achievement in itself?)
F. So, on balance: success or failure?
For sources of information, I’d stick with news and universities. Thinks tanks and editorialists will give you a lot of conclusions but not much information. Remember that school assignments are designed to show the teacher how much you know about the topic. So I’d focus on laying out the facts and save the judgments for one paragraph at the end.
The PBS News Hour did a good job of explaining the background to the conference before it started (www . pbs .org/newshour/updates/international/july-dec09/climate_12-07. html). A fact sheet from Columbia University also set the scene well (www .columbia .edu/cu/mpaenvironment/…/Copenhagen_Web_11-22.pdf). The British newspaper the Guardian gave a lot of coverage to the results of the conference (www . guardian.co .uk/environment/copenhagen), though note that its assessments of success or failure were quick judgments and that different writers disagree.
JW- Here would be my strategy:
1- Start with 3 (if you haven’t done it already). You can help yourself by using online translation and conjugation sites (just don’t do it to often).
2- Do a victory dance and take a (MB) break.
3- Start the human rights thingamadoodle. Get worked up about it and write passionately if you can, if not, just hack your way through it. That shouldn’t be such a hard topic to argue/write/whatever about.
4- I admit that I didn’t much pay attention to the CCC, since I found that it was a flop. Old *lastname* strategy: slowly inch your way away from the topic and talk about something easier. Make sure you end and start with the CCC, but usually you can sneak in little anecdotes about how important climate protection is. Mention the pollution in the countries where whatever politicians you happen to talk about come from. If your teacher’s sentimental, you might be able to squeeze in a bit about …and the factories which pollute the environment in china also take away habitat from adorable fuzzy panda bear babies, which *blablabla* but apparently this was not considered in the CCC, which was also attended by… Okay, not like that, but you’d be surprised how much teachers miss. If you add some little superfluous bit every paragraph, you’ll end up with a long enough essay.
5- Celebrate. Decide if you’re strong enough to continue.
6- If you can, do the project. If not, tell your teacher that you couldn’t finish it up because you’ve been trying very hard to make it excellent; you take pride in your work and would be ashamed to hand in something half-baked, and since the other teachers have been giving you such much homework and you needed to move upstairs you only had time to do a mediocre job, but since you love photography and were counting on trying to impress your teacher, if you could please, please hand it in a day (or two) late? You’re really sorry and understand that there’s no good excuse for failing to have your work completed on time, but you’re confident that your final product will make up marks off or any lateness.
Great. Rough draft of CCC done. Onto French.
Yes. Good. Everything is done except for the photo project, which is really due Monday. Thanks everyone!
Bio bio bio…. oh, how I hate thee, let me count the ways. 1, 2, 3, 4…. 2,000,999, 2,100,000…. *sigh*
I ought to love biology, ’cause my mom’s a biology professor and my dad’s a chemistry teacher and we’re doing a biochem unit right now. However, my teacher sucks and my textbook sucks and bio just generally sucks.
*sigh*
I loathe philosophy. I have to write an eight page paper supporting either Hobbes or Machiavelli’s theories before tomorrow. Reading this stuff makes me feel…I don’t know, morally skeevy or something. I know I don’t necessarily agree with any of it, bu ti have no idea how to properly express myself.
(Procrastinating, procrastinating…)
SFTDP, but I also have to write a speech for Model UN on Netherlands (the European Union’s really) stance on the Defamation of Religion resolution. (due Tuesday) And 25 index cards containing quotes for my sources for my Senior Project, an outdated and useless phenomenon my school forces upon those who wish to graduate (along with 200 hours of community service, of which only around 50 are complete). The index cards are especially useless because I don’t typically use index cards anyhow. If I do, I fit all the information onto two or three of them. And my Arabic teacher is out to get me, so I don’t dare miss any of her homework. and her class is first period, and if I want to get this stuff done I’m going to have to either skip school tomorrow or pull an all-nighter. If I don’t skip, I going to fall asleep during all my classes, have a horrible temper for the rest of the day(not good thing to have with teachers out to get me) and won’t learn much anyhow, my head will be so fuzzy. Skip, and miss the lesson, tests, quizzes, etc and have to spend even more time catching up with them. Or I could just show up with it unfinished, and beg for leniency, but I already have a reputation for turning things in late and I want to improve that, at least until I get accepted into a college and the final school report is sent out. Speaking of college, there is still the UM application due Feb 1…
I am beyond panicking at the way my life has spiraled out of my control. All I feel now is a sort of dull despair.
Yikes. That is a lot. Here is a tip that will kill procrastination: GET RID OF EVERYTHING. Go to a completely empty room and write/type. If you have to use a computer, clear your browser’s everything so it is more inconvenient to sidetrack onto something else. Get someone else’s views on Hobbes/Machiavelli. If you have voice command on your computer, it might be easier to speak to your computer and brainstorm, have it type, then correct it after. Good luck!
The “Defamation of Religion” thing made me convulse in anger. It’s essentially limiting freedom of speech in a severe way, giving religions carte blanche to be as offensive as they like. Christopher Hitchens was livid about it, look up some of his interviews on youtube on the subject or google some of his articles.
As for philosophy, well, try drawing a parallel between Machiavelli and modern American politics. I’m sure you can pull 8 pages out of that, if not more.
I’m supposed to be working on History Day with Ella, but I’m totally off-topic. So is she. She wants to write something, here:

How do you stay on topic? It would be oh-so useful right now.
55- Um… what? *glares at chatspeak*
Anyway, does anybody know the genus of a squid? Science homework.
((URGENT MATH QUESTION!!!))
Yet another Math question from you’re don’t-go-to-for-help-with-math friend Fishy:
“A swimming pool 20ft by 40ft, is surrounded by a walk of uniform width. The area of the walk ONLY is 1216 square feet. Find the width of the walk.”
I get what I need to do, but how can I set up an equation without having more than one variable?
Not sure, but I think it should include full area of swimming pool (2016 sq. feet)
Actually, that’s the one thing I figured out.
Er. What I figured out:
(20+2x)(40+2x)=416
FOIL that, subtract 416 and re-factor. Have fun with that.
Yeah, in other words: I hate this kind of problem, but unfortunately we were working on these not too long ago, so I think I know what you need to do. So, draw the diagram (you probably already have), figure out the area of the pool, then figure out the area of the walk itself from that. Then, label the distance from the pool to the edge of the walk (both of them) x. You might try doing something with the perimeter too.
Sorry I’m not much help…
Oh, whoops. Area of the walk only? That changes things somewhat. Ignore me. This makes my brain hurt.
Let’s see. There’s the four squares and the four rectangles, so…
2(20x)+2(40x)+4x^2=1216
Quadratic Equation.
What would the Let Statement be for “x.”
Quadform is
x = (-b +- Square root of b squared – 4ac) Divided by 2a
Using my Quadform program that I just learned today for my calculator,
a=4
b=120
c=-1216
x= 8 (-38 alternative)
x = 8 or -38
I didn’t want to say the whole thing.
If you sketch it out, you’ll see that the area of the walk equals the perimeter of the pool times the width of the walk, plus the four extra squares in the corners. If w = the width, then
area = 1216 = (20+40+20+40)*w + 4*(w*w)
= 120w + 4w^2
Dividing both sides by 4 and rearranging gives
w^2 + 30w – 304 = 0
which, after a little poking and prying, factors to
( w – 8 ) (w + 38) = 0.
[Later: I see that this is exactly the way cromwell worked it out earlier.]
Hm, I wonder what it would mean for the walk to have a width of minus-38. Would you be paving over the pool?
The math teachers say to reject negative answers (for shapes), but of course one must wonder…
FISHY. Our class learned the exact same thing today. Is your math class D block with Mr. J?
Sadly, no. But I do go to D wing…. Curious…
Distance is never negative.

In Euclidean Geometry, at least.

I just had an epiphany. I would still appreciate help.
Help with what?
Does anyone have any good memorizing techniques? I have to memorize a poem by Wednesday (!!!) and I need some help.
I have a good one: you’re going to need a nice inky pen and a hand.
The poem probably tells a story with a logical progression. Read it over a few times to “ease into” the story, then start to work on it from the top, remembering the “landmarks” that lie ahead. It will take a while, so don’t get discouraged. Just do it as many times as you need to.
Another little tip. Learn the last lines first.
People usually put the most effort in at the beginning, so that’s the part they know best. That often leaves them floundering toward the end, especially if they’re nervouse. If you know the final lines best, when you recite you will be moving towards the area of most confidence instead of away from it, and you can make a solid finish.
Any parts you can visualize will also aid memory, as we tend to recall pictorial images better than words.
More tips:
~ recite out loud. The more senses you engage, the more memory circuits you will establish.
~ walk around (or dance) while you recite. Again, it engages more senses. But movement helps in its own right.
That’s a very good idea. Then the big finale will be like coasting downhill!
One of my choral directors tipped me off to that. We actually learned whole songs in backwards order, a section at a time. It’s really most helpful, in psychological as well as practical terms, especially if you’re shaky with nerves at the beginning or stumble along the way. You know the easiest part lies ahead of you.
Another little bit about memorizing verse. The actor Laurence Olivier claimed he learned Shakespeare by memorizing the rhythm rather than the text — almost as if it were a piece of music.
One approach to this would be to record yourself reading the poem, then play it back over and over, until you can hear the “melody.” Then you’ll know if something is wrong as you recite, because the rhythm won’t sound right.
You could play one line then try to recite the following one. Then start over and try to recite two lines at a time. And so forth. I used a similar technique to learn lines for a play (used recorded cues) when I had a lead role. I learned my part very quickly and was the calmest I’d ever been during a performance. Didn’t miss a single line.
Write your poem on a card and look at it every time you have a break: standing in line, waiting for class to start, waiting for something in the microwave to heat up….you get the idea.
I could go on about this for awhile… But most of my advice comes down to recruiting as many senses as possible and using several different techniques. (Which also makes it more fun.)
Mostly the key is: time and repetition. Learning something in short sessions over a period of time will give your brain a much richer network of memory than a long cram session. That will also increase your likelihood of remembering under stress.
*has to memorize Quran* *should probably be taking notes*
This advice is more or less what my Quran teachers have told me since forever…
Are you a visual learner? Auditory? Kinesthetic?
It can help if you not only read it in your head but listen to a recording, or read it out loud to yourself.
Also I wrote that and forgot to post it for several hours… so some people have already mentioned this, oops.
Thank you! Those sound like really good ideas!!!!
Make a song out of it somehow; perhaps what Rebecca is suggesting. I know 189 digits of pi by heart just from listening to Hard ‘N Phirm.

I memorized 223, or so, roots and prefixes and suffixes these past three days. I was emotionally drained when I decided I finally knew all of them. ( Fin – end. )
( Pre – before, preliminary. )
( Mem – remember. Ize – I forgot. This was my emotional draining point. NOOO – TEST TOMORROW!! )
Latin test tomorrow… I have a very bad feeling. Very, very bad. Partly because I was supposed to catch up when I skipped the grade but sort of spent the time staring into space instead of learning sim, sis, sit e.t.c…
58.1- The math problem I posted.
UPDATE- I learned an easier way to do that today… “X” is the uniform weight, so you add 2x(The distance between the sides of the smaller rectangle to the edge on BOTH sides) to the length/width of the smaller rectangle (the pool), and then foil, get the same quadratic equation, set it to zero, then factor!!!
I’m sorry, is there a Wikipedia-to-English function anywhere online?? Hello??
Or could someone just tell me what a socialist government is, please? Someone who speaks Eighth-Grader?
Socialism is a system in which the government runs the economy. What are you trying to find out about?
There’s a question on my homework that says “what is a socialist government, name a country with a socialist government”
You could always use simple wikipedia. Google “simple wikipedia.” There is an article on “socialism” there.
Or you could listen to Robert, who basically summarized it in one sentence.
Grr – SHOULD be working on packet, but it’s so stupid!!!!!!!
A physics question (paraphrased) that I really should be able to answer.
You are a milkman. Your horse refuses to pull the wagon, because of Newton’s Third Law. He claims that he can’t possibly pull the wagon, because the force the wagon is exerting on him is the same is the force he’s exerting on the wagon. Why can your horse actually pull the wagon?
So what’s the answer other than “Why am I a milkman?”, “Why am I still using a horse in this day and age?”, and “Why does my horse talk and know Newtonian physics?”. I should know this (I’ve studied Newton’s laws before), but I’m not getting it.
The forces are equal but the acceleration is not. Horse accelerates more then wagon or something like that.
TMFA is right. The force on each (the horse and the wagon) is the same, but since the objects have different masses, different static friction, etc., they are moved differently by the forces.
Hmm… I think that Piggy’s answer is closer. Conferring with a friend who took the class last semester was helpful.
If it isn’t too late, I’d say that what the horse means is that the force and counterforce should cancel each other out, no? But they can’t, because they are applied to different objects. Or maybe I just didn’t get this one…
Can I just say, and I think this goes for Fishy too, that History Day is a big huge pain in the pie?!
And Pseudo and Keiffer, of course.
STFTTP. And Princess has finished saving the pictures for her documentary to her flash drive.
Has anyone read Ellen Foster? I am confused as to the end of Chapter 10, and we didn’t get the chance to discuss it in class today because half of our LONG BLOCK was taken up by a discussion involving job discrimination against pregnant people and people with one leg. At the end of it, our teacher lectured us on COMMON SENSE. ‘Twas amusing.
I hate my math homework. It’s on solving linear systems using substitution and it’s difficult and I’ve had to star two problems already. RARGH.
Anyone know organic chemistry? In particular reaction mechanisms. In particular the mechanism for oxidation of alkenes with permanganate. I have to do a presentation on it tomorrow. I’ve tried Googling, but everything I’ve gotten is a really long journal article for some obscure case of the reaction, which I definitely can’t follow.
This really is a 911! So, I’m writing a DBQ essay on…. how democracy and monarchy developed in England from 1066 to 1689, and I need a quote to start out the essay. What I want to know, is if “He who placed me in this seat will keep me here.~ Queen Elizabeth I” is a reference to God. I think it will work if it is.
SFTDP
Eh, I just said it was. She probably wouldn’t know anyway.
Note to self: Never ever ever be creative of photography projects. NEVER. Now I have to pull it off- I’m so cake-covered.
So. Comparisons and contrasts to draw between Hester Prynne (Scarlet Letter) and Richard Wright (Black Boy). Has anyone got any ideas?
I haven’t read Black Boy, sorry. Is Wright an outsider?
Maybe we need a new one of these threads…
In summer?! That’s sad, if true.
Hah, it is true for me. And I need help.
I’m convinced. So be it!
