I am a materialist (99%) and believe that if somebody hits something on my head with force, all my emotions, feelings, thoughts and even life would vanish in an instant. Yet, a few days ago something happened like this... I was sitting in my room at night and there was an electric cut...

Alright.I am preparing for engineering entrance exams next year.Most of the standard questions of Classical mechanics requires you to imagine the whole scenario in 3D.Unless you are able to vizualize it,You can't solve the problem.I am able to vizualize 70-80% of the problems but my imagination...

I was pondering over this problem about ratios and wondered what does 3/2 (oranges:apples say) actually means. I then understood after giving some thought that you DIVIDE the oranges with the no. of apples so that you get an idea about how many oranges correspond to 1 apple i.e. how much of one...

After reading an article a few of you may have read before, Link: http://www.metropolismag.com/October-2009/The-Making-of-a-Design-Thinker/ There are a few questions I am curious about. Design is not only the creation of prototypes for different machines/parts etc. But it can also be...

Hello, I would like some advice on getting a second Bachelor's degree in Computer Engineering. I currently have a Bachelors degree in Electrical Engineering. I should've gone for a C.E. degree since it was only 16 more credits but I didn't think it would matter much, so I didn't. Now I'm...

Hi guys:Just wondering, are there ways that you can improve your thinking skills hence enhancing your problem solving and learning speed and ability?

What are the requirements for getting research jobs in Astronomy and Cosmology? Where did you go to school/what job did you end up getting? How hard would it be to work towards a degree and work full-time? Are there jobs/internships that help pay for schooling while working in the field? And...

You're in an empty room. You have a pen and paper. Every 10 seconds you have to write what you did for the last 10 seconds. What would you write after 20 seconds? Think 'outside' the box (no pun intended).

Now, I'm aware that the best time to learn a new language it during your toddler years. This got me thinking. What if the best time to learn logical thinking is also during this time? I know for a fact that kids are not taught critical thinking skills. I tutored many kids and only see them do...

Hi all, I've had an itching lately to dive into something new. Currently, I am a professional computer programmer but have always been interested in astronomy. I took an astronomy course (as well as a lab for it) when I was in college and I remember enjoying it all immensely. I want to get...

I thought today of the next DE: y''(x) = y(x)e^{y'(x)} Not sure if it has applications, obviosuly I tried to find a solution via power series around x=0. It seems tough to look for a general recurrence equation for the coefficients. Here's what I have done so far. y(x)=\sum_{n=0}^{\infty}...

Hi, I got my undergraduate in Electrical Engineering. Then went right to work at a government sponsored research lab. I got into a part-time masters program from a good school and got two non-thesis masters: one in Electrical Engineering, the other in Computer Science. The reason for two...

So I'm still at my little old community college, currently taking a differential equations course (which I love), and then I'm taking a circuits and devices class (the first real engineering class I've ever taken.) I'm taking a couple other classes but they are mostly credit fodder so I can...

All right guys. A lil history bout me. in high school (10 years ago) i hated math, now i like it. Never went far with it in high school. Failed trig a year and a half ago. had to retake. Now I am in my first EVER calc2 class. Finished calc 1 with a high 80's (87 or so). Now I am in calc2 and i...

I'm a physics major right now, but I've figured out that I'm just not smart enough to complete this. I struggle with every aspect of this subject. And I used to like physics, but the more physics classes I take, the less I enjoy it. How long would it take to complete a bachelors if I switched...

So basically I have always wondered what motivated Einstein to move from Special Relativity to General Relativity. Anyone care to tell me what was going on in Einsteins mind after he completed his Special Theory of Relativity? I have done a course in Special Relativity, understand it and I...

I have a question that maybe basic and psychological in nature but I'm hoping someone with experience in Neuroscience research or any related fields could answer it. As far as I understand it, there is a common debate as to what influences human decisions and what does not which leads to the...

Wondering if anyone could enlighten me as to why I can lay in bed in hours, trying unsuccessfully to sleep, while my brain is going on a roller coaster of thoughts. It doesn't happen every night, but it is frustrating since I never remember what I was thinking about in the morning.

I'm a graduate student in experimental condensed matter physics. Over the last few months, I've found my motivation for physics decreasing substantially going from "I'm definitely doing my PhD in this" to "grabbing my MS and change fields"; now I'm not even sure I can withstand the MS. As I...

If a neutron in a nucleus is in a 1p state, before splitting this up into separate j-state (due to spin-orbit effect) this neutron has 6 possible states. l = 1 m_l = 1, 0 or -1 m_s = 1/2 or -1/2Splitting this into j-states corresponding to l+s and l-s, as expected there are 6 states. j = 3/2...

Hello there, As the tittle goes: I'm thinking of taking Physics as a major but could it limit me? I've done some googling but everybody seems to contradict themselves. I'm finding hard time deciding on a program, and I don't have much time left until the deadlines. I'm pretty sure that...

A little about me: I graduated with dual degrees in Psychology and English about two years ago. Since then, I haven't had a professional job which pays a good wage and have even had employers tell me that I need a stronger math proficiency. I heard that engineering and math/based fields are...

So, about 3 years ago I was on these forums getting an idea of what I wanted to do after I got out of the military. My how time flys because my military service is almost up as I have a little more than a year left. My job in the Air Force is an avionics tech on fighter jets. I love my job...

What is the fundamental premise of "positive thinking" The only quantifiable effect of positive or negative thinking that I can think of would be how each mindset influences your actual behavior. But do positive thinkers believe that it also somehow produces effects via some unknown mechanism...

During this year, I was studing classic physics again ,which contain mechanics and electrodynamics.They are both irrelevant to thermodynamics,and irrelevant to statistics. In mechanics ,we have the Newton's laws of motion,which can be in the same form in any inertial system,that is to say...

Does Thinking Make You "Smarter"? I've always had an unspoken, unverified assumption that playing any game that uses a lot of mental power will make one "smarter." How do I define smart? As basically anything that improves brain function. I guess my question is: does the brain work like a...

Hi everyone, I'm looking for a bit of advice on how to approach my situation. Any input will be much appreciated, no matter how blunt. My situation: I completed a BSc in Math (Honors - sort of a masters equivalent for those not familiar) in the middle of 2010. After finishing I kind of...

I'm having trouble with the concept of conservative forces. I've been studying things of that nature for awhile now and can make most calculations on my own, but there are a few specific details that confuse me. It's easiest to explain my confusion with two simple examples. First Example...

I have 2 questions. I have been thinking about these two things a while, and got no one to ask, so hope to get some info/answeres here:) 1: When an electron is standing still, it produces an electric field (and no magnetic field), right? So when many electrons is moving with a constant...

Hello Forum, electrical power is current times voltage. Current is charge per unit time, crossing an hypothetical surface: the more people cross a door per unit time the higher the current. Voltage is energy per unit charge: the more energy each person crossing the door, the more the...
