Why can't you look this up yourself, sammy7?

This:

The lecture notes of the professor who taught my fluid dynamics class: http://farside.ph.utexas.edu/teaching/336L/Fluidhtml/node17.html It's written in a different form, but you can check the previous chapters to see how it was derived.

MIT has you send in "evaluations" from teachers: one from a math or science teacher, and one from a humanities, social science, or language teacher. Here's their page on evaluations: http://mitadmissions.org/apply/freshman/recommendations The idea is that a teacher who knows you well will write a letter to MIT explaining why you're a good student and should be admitted to MIT. So you want to impress two teachers with your academic ability and your personality -- not just "this student is smart, so you should admit him", but "this student is smart and fun to work with, and I enjoyed having him in my class." I'm not sure what extracurriculars to recommend. Go out and do what you enjoy. If you can get into a leadership role (president of the chess club, or whatever), that's even better. Just do something, and be able to say on the application why you enjoy it and what it involves.

Here's MIT's page on international admissions: http://mitadmissions.org/apply/international/howto They say: For MIT, you'll need more than high test scores. Extracurriculars are good; in fact, I think they're essential, because gets so many applications from students with perfect scores that it has to distinguish students with extracurriculars. Work on getting strong letters of recommendation from teachers and others. I may be a little bitter; I was rejected from MIT despite high test scores, probably because I had no interesting extracurriculars.

The only reason this would occur is that as the contraption rises, it lifts more hose off the ground, consequently becoming heavier -- or the water isn't able to climb up the hoses, and the flow from the nozzles decreases. Otherwise, constant flow from the hoses will cause constant thrust, and the object will accelerate upwards. Similarly, the Harrier has a height ceiling because its thrust decreases with altitude. If the engines kept constant thrust, there would be no limit.

I'm not sure I understand your question. If your jets push out a specific mass at a specific velocity, their thrust is constant, independent of altitude. You can rise as high as you want. The practical problems only come in when your engine thrust decreases due to thin air at altitude. Harriers, for example, are known for entering hover at high altitude and high speeds to suddenly decelerate, causing a pursuing aircraft to overshoot and become vulnerable to missiles.

If you're having a problem sending private messages, why not ask us for help resolving it? Nobody has disabled your private messaging system, so the only possible problem is that you have more than 500 PMs, which exceeds the quota; if so, delete some old ones to free up space. Otherwise, ask us and we can help resolve the problem. If you object to a specific moderator action, use the Report link attached to their post. I can't make a meaningful comment about your accusations without knowing what actions you're talking about. Incidentally, I would greatly appreciate it if you'd stop insulting our staff by private message. It's getting tiresome.

The title is tied to post count: http://www.scienceforums.net/topic/104-user-titles/

The cdot spacing I do not know the answer to. We use standard LaTeX, so the equations render just like any other LaTeX system would render them; that's not in my control. Putting line spacing in the midst of a [math] tag is probably a bad idea, because LaTeX is not amenable to line breaks in equations. You want to do so outside of the math tag, or use the \begin{align} environment.

Ah. They're a couple years out of date, since we moved to the new software. If you hit the little icon in the top right of the editor, you'll get a list of current BBCodes.

I'm not sure what you mean. Changing the LaTeX at the top shouldn't change anything later. Now, putting LaTeX in paragraphs will make them spaced funny, because the equations are taller than normal text, but there's not much that can be done about that.

The editing time limit is ten hours. You can use the Preview Post feature to play with LaTeX -- enter some LaTeX, hit Preview Post, and see what comes out -- or you can use the LaTeX Whiteboard: http://www.scienceforums.net/math/ It uses the same LaTeX system as the forums do, so anything that works there will work here.

If you want to separate formulas on different lines, do something like this: [math]3x^2[/math] [math]\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/math] Hit the Reply button on my post to see the code I used. I've never used mathop, so I don't know what it does.

If you consistently put in good work, you should be fine. However, you must be quick to recognize when something is hard because you're missing a more fundamental skill. For example, you might find that some of your chemistry problems are hard because you have trouble with some of the math. Don't just study harder on chemistry: find a tutor or a book to help you with the math, so you can succeed with the chemistry. Quite a few people don't recognize this, and so they just try to memorize ways of solving problems, instead of learning their missing skill. They end up struggling through classes. Colleges always have a pile of opportunities to get help: study groups, tutors, TAs, office hours, and so on. Make use of some of them. (Study groups are good; you get to screw around while pretending you're doing work.)

Which rules? Moderators can neither see nor delete your private messages, unless you intentionally send the messages to them.

So I've just read all of Neal Stephenson's Baroque Cycle (Quicksilver, The Confusion, and The System of the World). The series is something absurd, like 2600 pages, but (mostly) interesting. Neal Stephenson doesn't write stories; he invents an entire universe, including all the details, and then chooses bits of it to write down. Usually too many bits, given the length of the series and the complexity of the plot, but it's usually fun reading. I also read Feynman, the graphic novel by Jim Ottaviani, which was a fun biographical portrait of Richard Feynman. As a graphic novel, it's certainly no in-depth biography, but you get a feel for the curious character of Feynman.

I find it amusing that you cite Dr. Fitzpatrick's lecture notes here, because this is exactly the sort of answer he would give to a question like this. There is no physical motivation. There is only maths.

I disagree. "Broken" implies some objective standard of correct functioning of humans. Humans have always been illogical, and yet they have prospered, so apparently the demands of natural selection have not required logic as part of our normal functioning. Similarly, a computer is not broken if it fails to make you pancakes. Free speech is not protected on SFN. You are protected from suppression of your speech by the government. We are not the government. Seeing as how imatfaal's prophecy in post #19 has come true, and iNow has not changed his argument, this discussion has come to its end.

I wouldn't be surprised if your clothes shrink quite a bit. Also, I don't think the autoclave will get dirt or smelly stuff out -- it would just kill anything alive on the clothes. I'd just get a sink and some Tide.

"Allect" means "to allure; to entice." Janus was being funny.

It's not always true that using more memory makes a program faster. If Matlab has all the data in memory that it needs, it may not have anything to put in the extra space. Imagine being asked to sort through a pile of papers and find an answer to some particular question. You'd want some desk space to spread the papers out, but beyond a point, having a football field of space doesn't help you any -- you have nothing to put in the space.

You'll want to take that up with ajb, then, since that's the report he linked to: http://www.score-education.org/media/10036/full%20maths.pdf

There's a link at the bottom there to "Read and comment on the full post". You'll want to follow that. I have blog posts syndicated on the forum so they show up in the View New Content system and are more visible.

How do you propose to create a non-shiny material which is 100% reflective of the entire visible spectrum?
