/sci/ - Science & Math

I am a Math and Physics double major, planning on trying to get my master's degree in Mechanical Engineering.

I have the opportunity to study abroad in Japan for a year and for very cheap, but they're all humanity and language courses and won't help my immediate degree at all and will just delay my graduation by a year.

Do you think that this will be worth it and look good for future employers in engineering/other possible work, or just a waste of time if I don't plan on working in Japan?

I apologize if I should ask this in /adv/ instead, but I figured there's a higher concentration of people with more useful advice for my situation.

OK, I'm trying to work out a timetable for studying for the next three months.
There are 31 topics of study under 6 major subject headings.. Each of these subjects are worth 71 hours of study.
The subjects breakdown into the ratio, in hours: (7 : 7 : 21 : 21 : 14) : (14 : 14 : 14 : 14 : 14) : (17 : 17 : 17 : 17) : (18 : 18 : 9 : 9 : 9 : 9) : (28 : 7 : 12 : 12 : 4 : 4 : 4) : (9 : 9 : 18 : 11 : 12 : 12)

Basically looking at this problem makes my head spin, how do I work it out so that I divide the topics evenly over the next 107 days?

If you had $100,000 and no limits on what to do with it what would you do?

I ask this because I'm considering becoming an engineer but I am not very "good" at math. Probably nothing that can't be fixed with enough studying, but I just wanted to make sure I'm not getting myself into super advanced mathematical concepts that I'll never be able to comprehend.

141 also, no questions missed. My favorite part of the intelligence analysis so far:

"Strengths and weaknesses

Your highest score was in Verbal

Exceptional intelligence does not guarantee results -- to achieve excellence you must fully understand your strengths and learn to maximize your efforts. Knowing your greatest intellectual strength may give you insight into how you can improve your learning process, work better with others, or become more self aware of your abilities. According to this test your verbal skills are the most developed of all your intellectual capabilities - your capability to use language effectively and to communicate well is your biggest strength.

Your lowest score was in Verbal

Weaknesses are the roadblocks we face when trying to achieve our goals. Awareness of your weaknesses allows you to predict problems and find solutions ahead of time, thereby alleviating future headaches. According to this test your verbal skills are the most underdeveloped of all your intellectual capabilities - your capability to use language effectively and to communicate well is your biggest weakness."

My professor haha. I was making sure I wasn't crazy before I go to him and point out that he did it incorrectly in class.

I may be slightly drunk, but could you not also use the law of sines?

The larger square is symmetric along it's diagonals, so the triangle with x as the hypotenuse must be equilateral.

x/sin(pi/2)=b/sin(pi/4)

x=b.sqrt(2)

bump

wrong OP pic meant to use this one

x = 0.999...

10x = 9.999...

10x-x = 9x = 9

x = 9/9

x = 1

0.999... = 1

Why is everything in the universe spinning/orbiting? Where does the energy to spin comes from? Will it run out?

The introductory calculus sequence along with linear algebra and discrete mathematics probably form a decent base.

The techniques learned in calculus are used extensively in areas like probability and differential equations, and of course calculus helps prepare students for more detailed study in real and complex analysis.

Discrete math courses tend to get into combinatorics, graph theory, set theory, logic and proof techniques, all of which (but especially the latter two) prove valuable in various upper level courses.

Linear algebra is also pretty proofy, and gets into the study of abstract vector spaces, which mentally prepares the student for thinking about other mathematical structures in courses like abstract algebra and topology.

Probably the greatest requirement for getting really deep into mathematics is "mathematical maturity," which is somewhat nebulously defined but generally refers to a certain way of thinking about and solving problems that develops over time through exposure to mathematics.

Stat people, I have a question:

What sort of regression would be appropriate for percentages. Like for example, an online poll. Let's say there are two choices, A and B and A is at 70-30. Then people who like A stopped voting while people who like B continued. I know that the more votes there are in the poll, the slower the percentage rises, so what regression would be right for this?

Why do geosciences not receive the same kind of attention as others? I mean it is arguably the most pertinent subject we humans will ever have to deal with, at least in the "short term", considering our very limited life span, and it is comprehensive in that it involves mathematics, physics, chemistry, and biology. I would also argue that it is the most important system to understand because we have to deal with it on a daily basis. It is also the most complex system considering all the different variables which act on it which makes it worthy of more attention. Am I wrong?

I should rephrase that.

What, in conditions A-K, would give rise to the existence of three spatial dimensions? Also how are these dimensions related to time?

Oh do please reply, I am interested in your theory and will fund you with a slice of my pizza.

That's cold, work hardened physics, brah.

You could only say that this is not science in the sense that we can't adequately measure or test for free will.

The reason for this, though, is merely because our capacity to analyze the brain (in its many dimensions) is limited.

Give computer science (specifically, artificial intelligence engineering) a couple decades and you'll have your answer, OP.

Physics problem I heard Brian Greene describe that he had in high school.

A piece of chewing gum attached to a baseball and the ball is swinging. Figure out the motion of the ball as the chewing gum stretches and it's swinging back and forth like a pendulum.

How do you solve it?

Good active physics chat rooms, do they exist?
