I'm a high school senior and I'm toying around the idea of double majoring in cs and physics, as I incredibly enjoy both fields. I aced AP Computer Science and AP Physics C(both Mechanics and EM). With AP credit, will I be able to complete a cs physics double major in 4 to 5 years without...

When I was in high school and first learned about the laws of thermodynamics, I independently postulated the heat death of the universe (of course I didn't know it was called that at the time). A few years later and I find out that some guys in the 1800s beat me to it. What do you think...

Oks, I've always been a passive reader of forum...Until now =) Im a ME student, finishing my 2nd year AND I am working 20hours/week at a well renown technology institue at my country. Working only 20hours per week gives enough time to study, so I am doing ok. Yesterday, another job was offered...

Homework Statement A light-year is the distance that light travels in one year. Find this distance in both miles and meters. Homework Equations Speed of light (c) = 3.00x10^8 m/s The Attempt at a Solution 10^15 m/s __________ 3.00x10^8 m/s That is to find meters...I think I can only find...

Don't remember seeing this. Does NASA do September fools jokes? I cannot imagine anything so CGI being for real.

So, five years ago, at a pretty prestigious North American univ, I was accused of cheating on a take home exam. I hadn't cheated, but unluckily, I made careless mistakes that were similar to where I was supposed to be cheating from (and this was on a predominantly maths based paper) and so I...

And man has technology in the classroom advanced at breakneck speed. I've only been away for 5 years and I'm having trouble trying to learn it. Is it me, or has technology actually made learning worse? Why can't things be simple anymore? All I want is a lecture, an assignment, and test. Now...

This is a follow-up to some of the advice I was given at the thread I created called "Shortest Path to a PhD in Math or Theoretical Physics" and here it is for reference: https://www.physicsforums.com/showthread.php?t=521408 After looking around on the internet here is a path which I could...

How come AI never makes an progress? OK this may be slightly over stated but it has been 50 years since we thought we could make an AI soon and we are no where near an AI.

I got a bachelors in physics in '08 at an upper liberal arts college. Intended to take a year off but fell into a depressed rut (father died, girlfriend left, etc etc) and just worked a low-skill job / volunteered / played wow for two years. Cleaned my act up a year ago. I'd surfed through...

I know this question has been asked a million times,but i haven't been able to find an answer for this. I am a Physics Undergrad and looking forward to pursue MS in Physics from US,but I have only 15 years of education (10+2+3). Most schools require qualifications comparable to a U.S...

[FONT="Georgia"] Greetings all. I apologize for the lengthy intro; I shall try to be brief. For those who don't think any background is necessary, you can skip to the last paragraph if you would like to save some time. For all of my younger life, I was always a math freak. Gifted...

Not sure where this goes. I like math but this is a little over my head. Can somebody do this for me and what branch of math is used? Our town has a goose manure problem so I'm gathering facts for my presentation. Here's the problem- If two geese produce 8 babies each year what would the...

Is it coincidental that the Hubble Sphere, in light years, is approximately the age of the universe computed as 1/Ho (13.7 billion years)? If the recession speed exceeds the speed of light, the photon would never reach the observer, this is why there exists a horizon of the visible Universe...

According to the legend, the island of Manhattan was purcased from the native indian population in 1626 for 24 dollars. Assuming this money was invested in a Dutch bank paying 5 % simple interest per year, costruct a table in C++ showing how much money the native population would have at the...

Will the big bang be seen as 13.7 billion years ago by all observers in the universe regardless of their velocities ? I mean I read that in SR one has to abandon notions of simultaniety. And an event which has already occurred for one observer may be in future for another observer. I guess...

Okay, If Uranium's half life is 4.5 billion years, why does it become waste at a reactor before it decays 4.5 billion years later... Forgive me if my question is badly worded or really stupid; I am a high-school student who has just finished the topic of "Nuclear Energy" in my physics class...

A star is 40 light years from Earth. (a) How far would you measure this distance to be if you traveled it in a spaceship moving at 1.00X10^8 m/s (b) How long would the trip last (for you)? Can someone please help me out with this question and what equations I should use to solve this...

I've been posing this question to physicist folk for 10 years, mySpace 6 years ago, and here (don't know when, when I had an older account), and I see that others bring it up on occasion. I will refine it to meet current objections. You have a photonic drive spaceship. It has a (classical) mass...

I'm currently in my third year of a 4 year masters course, however I've been offered a place on a PhD scheme which would mean me graduating with a Bsc instead of a masters and starting the PhD right away. My question is: Does having a masters as well as a PhD differ significantly from having a...

Recently I saw this in the news...any thoughts on this? jhd as joesmith

Huguette Clark, daughter of Las Vegas founder and second richest man in the US at his time, William Clark (Rockefeller bested him) is dead, at 104 years old. It is said that compared to her, Howard Hughes was an outgoing&sociable man...

Currently I am doing my MSc in Physics with a focus on Condensed Matter Theory. I have about one more year to go, after which I will have to decide how to carry on. By the time I finish my Masters I will be 23 years old. This summer I will do a well-paid internship in the financial sector at...

I don't remember specifically where I read this, I think in a post here, but is it true that PhD programs prefer admitting students who completed their BS in 4 yrs over those who took longer? Ive already been working on my BS for 4 years and am trying to decide whether to cram and finish in...

Hello, I would appreciate advice, preferably from people with families. I am currently plodding through a degree in physics\math at a snail's pace, due to working part-time at unconventional hours (in informal education) and raising a 1.5 year old. I also observe the Jewish sabbath, so...

For years I have mastered the art of simulation and testing, but I almost never seem to be able to find SPICE models for real devices. For example, the TI OPA548. It's a high-current power op-amp. I would love to run some simulations...but I can't find a model of it anywhere to use in...

Hello folks, I graduated 10 years ago with a PhD in theoretical atomic physics and went into the IT industry. My career to date in IT has been successful, however it has never challenged me and recently I have had a great yearning to get back into research. So I have been getting out all my...

In the UK, following the Bologna process, any undergrad degree taking 4 years, assuming sufficient amount of credits is obtained, one is awarded a Masters degree. A 3 year course results in a bachelors. Why is it that in the US, one is awarded with BS after 4 years of study? Is it because of the...

Hi, I am worried my son probably going heading down hill with absent/missing ACA A1 segment. He is also has very poor vision (OA) with nystagmus. He has hemiplegic event last years by treating his sinus issue somehow has positive effect for 8~10 months no hemiplegic events. Last week he had...

What will be happening 10^(trillion) years from now? Sorry if this is posted in a wrong section.

Hi, I've just been wondering about something so if anyone coudl explain it that'd be great. You often come across the statement that we believe the universe to be 13.7 billion years old, but I was wondering how this calculation is made? My main problem is that I'm confused as to whether every...

According to the Milankovitch 100,000 years cycles, there is a problem. The orbit of the Earth will change to a gradually more ecliptic orbit, and it will be a bit colder when this happen. But the problem is that this is not enough to explain ice ages. How much is missing. I mean how much...

The universe is said to be 13.7 Billion years (http://en.wikipedia.org/wiki/Age_of_the_universe" . So, for the present galaxy UDFj-39546284 and the present Earth to have traveled as far as they are now, and even if we assume that the big bang occurred right between Earth and UDFj-39546284, it...

I hear a lot about astronomers using type IA supernovae to accurately measure large scale distances over billions of light years to do things like measure the rate of expansion of the universe. I doubt that the calculation of this distance is simply based on the inverse square law. So my...

Not sure if this is the right forum but i'll ask here anyway. I'm a student going into a mathematics program in the fall but I'm wondering if i can still do a hobby. But here's the thing. To understand math, i literallly have to do all the homework my teacher assigns each class. This is roughly...

I was a mechanical engineering major that recently switched into physics. Given my late start, I'll be taking most of the physics curriculum in 2.5 years. Is this enough time to adequately prepare for PhD work? Since I'll be taking quantum my senior year, I probably won't take the GRE until...

Mr. Frank W. Buckles, who signed up in august 1917 died this Sunday. He was the last living US veteran, and will rest at Arlington, according to his own wish: http://www.washingtonpost.com/wp-dyn/content/article/2011/02/28/AR2011022800165.html

This is a case where the law prevents the right thing to be done. It appears there is an easy solution, but no one wants to do it. A simple court order could fix this. continued...

I have already completed all of my liberal education courses except for one during high school (College Classes). Right now I am a freshmen, so I was hoping I could graduate in 2014, but that may not happen. The problem is that all of the physics courses are only offered during either the Fall...

would we be able to see a total solar eclipse after about 600 million years from now?

Every so often I read articles about how you can save a lot of money simply by negotiating your bills down. One even noted how it can be the perfect new years "resolution". While it's not a resolution per say, the idea is when the first of the year comes around, call all of your cable/cell/phone...

Sorry it's not the best Latex, I hope that you can still help me grasp this. y=2xy1+y(y1)2; y2=C1(x+1/4C1) So, the solution says to implicitly differentiate and gives y1=C1/2y So, how did they get the derivative to be this? This is the first chapter in my DE class and I'm rusty with my...

Do you think that they are better at teaching the course or worse at teaching the course, as compared to newer professors who might have taught the course for only a couple of times? Obviously, I realize that there is no clear-cut relationship. *But*, there are certainly patterns to look for...

I am surprised there was no thread about this already, or maybe I shouldn't be depending on the response. What is your New Years Resolution? I haven't picked one yet, but I am leaning toward working on not procrastinating so much... but I think I will wait to be sure.

Last year Astronomers observed a self-destructing star 13.1 billion light years away. Happening only 630 million years after the big bang. While it is amazing that we are able to observe objects that far away, questions arose. Now for a moment, let's imagine our universe in it's 3 axis (y, x...

After the end of this semester my GPA will be at a 2.8... I know what happened, for about two years, I did not know what I wanted to do in terms of a degree, wasting time with various elective-based classes until I figured out what I wanted. In the meantime of wasting time, I procrastinated a...

It's been a blast these past 6+ years. If you need to get in touch, search my handle -- there shouldn't be too many of me around. Or just wait around: maybe I'll be back some day.

Hi, I was thinking about taking a specialist physics and mathematics course at a Ontario University. Do you think that if I get a good GPA, say 3.5+, I would have a great chance at getting in MIT's masters program? What should I prepare for in my BA program to better my chances?
