According to Ed Barnes reporting for FoxNews.com http://www.foxnews.com/scitech/2010/11/26/secret-agent-crippled-irans-nuclear-ambitions/ I like that kind of war: Clean, quiet, casualty-free. Congratulations to George W. Bush?

As I have mentioned in this thread, it's that time of decade where I'm looking to build a new computer for myself. I'm hoping to not spend more than $800 CAD on the motherboard, processor and RAM but I have no real budgetary limit. Of course, I'm looking to optimize for some metric of...

I'm looking to build a new computer for myself but it's been a while since I've done so and I find the market to be more confusing now than ever. Are requests for such advice welcome on these forums? I figure a question on forum protocol would be more welcome than a blatant violation of...

What is a CS course that covers how software and hardware are connected? This probably seems simple to most but I have no clue as to how this interaction works. A lot of the courses I've looked up seem to be either hardware or software only. Also, is there a name for this area of CS so I can...

Howdy All! I have been lurking in the shadows of physicsforums for a few months now, but this is my first official post here. A bit of background about me. I'm technically in my second year of university, but I say "technically" because I more or less squandered away my first year. I'm...

If not official, then unofficial, but widely accepted? If yes, are there some separate style guides for physics and computer science texts?

hi physicsts I had completed my b.tech in computer science and engineering and want to pursue a career as a good astrophysicst. Now in India there is an intergrated Msc-PhD programme at indian institute of astroastrphysics and they allow b.tech grads to do astrophysics if they have good...

What kind of careers could I get if I majored in computer engineering with a minor in physics? Or does a dual-major in compE and elecE make more sense? Which is better for grad school? Thanks!

I don't know much about how to work with computer softwares. Would you please suggest em some simple CAS which also supports text feature. I want to use it to simply write down math - I can solve problems (such as calculus ones) myself. Thanks for your help.

Today when I was sitting at my desk in the lab, all of a sudden I saw fire in my PC! So I cut off the power in a hurry, and opened the case to check it. Then I turned on the power, and to everyone's surprise, it started up normally like nothing happened! At that moment I was totally ...

Hi Every one, I'm a mechanical engineering graduate working in software quality assurance. I'm planning to learn the fundamentals concepts of computing and pursue an MS in computing which would enable me to get into research or into tech companies like google. Could anyone explain what areas...

Hello, first of all I want to say english isn't my primary language (I'm from Quebec), so I'm sorry if you have trouble understanding me. I will be attending university next year (I think this is what you guys call undergrad school in the US, with one less year since we have "CEGEP" between...

Hello, I am currently a senior in high school. So, since colleges are just around the corner, I've been thinking of getting myself in an engineering school to study computer engineering. My dad wants me to get involved in software engineering, which actually sounds appealing to me. I enjoy...

Do I need physics in college if I am majoring in computer science?

Title kind of explains what I'm trying to do here. I know exactly how radix sort is SUPPOSED to work but I just don't have a clue how to go about coding it. Basically what I am asking for is some java based pseudo-code just to get me in the right direction. I'm specifically sorting an...

I've done quite a bit of reading already on this but none of the solutions I've found seem to fit my situation. I can run older games like Knights of the Old Republic just fine, but more graphically intense games like Battlefield Bad Company 2 or Assassin's Creed 2 will result in my computer...

Moving forward after the "useless" Computer Science Major Let's face it, general consensus is a CS major is about as useless as you can get when it comes to the sciences. While you're taking your undergrad, they fill your heads with these lofty ideas and practical uses of computer science...

I am interested in the field of Quantum computer/Quantum computing. with which books I should start, and what are the 'must read' books in this domain?

What is the main difference between the two? They seem to be very, very closely related and I'm having difficulty deciding between the two. Help me please~

Hi all, My objective is to understand the electronics of a computer. It does not have to be a modern computer, but I want to know how the basics of digital electronics (like flip flops, gates, counters) are assembled togather to get the desired output. Its more like how the individual...

quantum computer... Is a quantum computer (a full fledged working) really possible..?? nishant

I have been helping my daughter over the phone with first year physics and have run into a problem with communication(insert your favorite joke here). It is difficult to describe a diagram that has vector, angles, notations and also associated equations. I would like to be able to freehand...

Hello, I am looking for something that can match and locate icons/areas of a GUI from saved images. Could anyone point me toward any projects? Thanks.

Just recently I was clicking through my itunes list and then my computer started going really slow and the music stopped. When I would switch to another window some random music started playing out of my list, then I'd switch back and it would stop again. I noticed that songs were being chosen...

I'm setting out on a project, and I need some basic direction. I am a programmer by trade; my father is a mechanical engineer who is pretty good at electrical circuit design as well---together we want to control a pipe organ by computer. The organ is already operated by electrical solenoids...

I've been reading "Programming the Universe" by Seth Lloyd, a quantum computer scientist. He goes on and on about the power of quantum computers and their ability, for example, to factor large numbers using massive parallelism. He also states that quantum parallelism is different than classical...

You would feed it experimental data and it would generate theories or mathematical structures which fit the data. The theories would then be run against related experimental data to see if the theory also predicted them as well. Slight mutations, mating successful ones ---> evolved theory...

Mine's an homage to memes (a work in progress :smile:): What's yours?

I absolutely love every thing about computer science. I love complexity theory, AI, machine learning, Theory of Computation, Algorithms, etc. etc. But I know that if I get a bachelors degree in computer science then I will just end up in a software development job where I don't get to apply...

I just downloaded a program called iCall that allows me to make phone calls from my computer. My only problem is is that I don't have a working microphone. I was wondering if there was any way to use a text to speech device to allow me to call someone, hear what they say through my speakers and...

Hi, I am not a physicist. I am trying to understand something about the behaviour of materials for computer graphics applications. I am trying to get an intuitive understanding of refraction. As far as I understand it - and please correct me if I am wrong - lightwave's phase velocity is...

I understand the formal definition for big O notation but is there an intuitive interpretation?. For example, if f(x) = O(x-1/4) is it reasonable to say that for large n f(x) grows at the same rate as n-1/4? Thanks in advance

Hey everybody. I'm a freshman in college thinking about double majoring in physics and math. I think I might want to try to get into physics research as a profession, and I think knowing how to program might help me. Someone, however, told me that computer science courses aren't the type of...

I'm exploring different career fields and a computer engineer sounds really appealing to me. The problem is, I don't think I have what it takes to become an engineer. I'm basically retarded with building things... for example, if you gave me a bed to assemble with the directions, i probably...

How would I make a new data type that would hold larger numbers than ones that we can currently use? for example I need a data type that can handle calculations from large factorials e.g 200!, = 200*199*198*197 ...... it's a really large number and can't be saved in ints/doubles/longs...
