Hello all, I am a new member here, but I have come upon Physics forums many times before. So, I have a question: Is it possible for me to gain a Bachelors in computer science and then move on to a Masters in an engineering field? I am presently a CS major, which I love, but I don't know if I...

Homework Statement Assume a transmission imaging system with the following parameters: focal spot PSF equal to a Gaussian with FWHM = 0.5 mm, a detector PSF equal to a Gaussian with FWHM = 0.1 mm, source-to-detector distance = 100 cm. Compute: 1. the optimal source-to-object distance 2...

The line between the observer and the observed needs to be re-enforced. Apparently science is a whole list of things nowadays, from evolution to nature. I didn't know nature was science. I did know nature was studied by science. Mainstream media and pop-sci is rampant with this non-sense...

I'd like to hire an astronomer to help me with a writing project (fiction). Do you guys have any tips on how I can go about doing this? The work should be somewhat simple (I would think at least), it involves crafting a fictional galaxy and a few star systems therein. Sorry if this is the...

So at the college I'm in I'm a freshman Chemistry + (any) Engineering major (don't have to decide on what kind yet). I was set on going Chemistry + Biochemical engineering but when I went to my adviser he told me maybe think of becoming a Material Science Engineer. He said something along the...

Compared to other things we humans do like singing, acting, painting etc. why math and science seem tougher and more challenging (at least to me)? Acting, for example takes a lot of skill but somehow when compared to the sciences (natural and formal) it is less challenging. Is it me or does...

I need a computer science class for my math degree. Should I take intro to C or intro to C++ . I know nothing about programming.

Is There any impact/will there be any: of the concept of Einstein’s New Ether in science today? I red that even though Einstein rejected aether in his relativity theory he introduced it back in 1920 to explain his theory of gravity. I don't know if he ever published it as a theory or it has...

Homework Statement The Monovacancy formation energy of a metal is 80 kJ/mol. Hence the monovacancy concentration (CV) at 25 degrees celsius is about: A)1.3x10^-13 B)9.5x10^-15 C).9 D)5x10^15 The Attempt at a Solution I know the answer is B but I don't know how to get to that. I...

How hard is it to know almost every area of science? I am majoring in physics and want to pursue a PhD in physics, but I also want to learn a lot of the other subjects like math, chemistry, computer science, and engineering. If I could I would pursue PhD in all these fields but that probably is...

What are the main differences between Astrophysics* and Planetary Science? What are their roles? And, which of the two is responsible for the first cloud map of a planet outside of our solar system? http://www.space.com/23043-alien-planet-cloud-map-image-kepler-7b.html *I mean just the...

I've seen the phrase used quite often, it's in the rules and the discussions, and I think I get the gist of it...but I'd like some clarity. By simple deduction, anyone could reduce all we know to the term of 'crackpotery'. Take this for example: The standard of "knowing everything" in the...

(I am going to attempt a 2nd, little thread before I finish my earlier thread. I want to see if I can practice using PF Rules & Guidelines and FAQ before I wrap up my thread on Autism in Medical Sciences.) In my humble opinion, the current budget crisis in the news likely augurs deep cuts -...

I would like to start a thread discussing the opportunities for Physics PhDs in the field of corporate Data Science. This emerging filed is briefly explained in the following article: http://www-01.ibm.com/software/data/infosphere/data-scientist/ I have heard on a number of occasions that...

How far can Physics help me in Computer Science, and in which fields?

Has anyone here completed undergrad or grad degree in one field and then decided to go physics? I have a bachelor's in CS and I'm wondering would i have to go full undergrad again if i would like a degree in physics. I've always loved physics and have completed couple of physics and math...

Hi, The first thing you probably noticed was how broad I was with the term science. Basically in a small sop story, ever since I was a kid I wanted to be a "scientist" at first it was fir mixing magical potions and becoming invisible but as time passed I think it's more the sheer thrill of the...

Greetings Physics formus, I am a high school learner currently in my final year of schooling. I have decided that pursuing a double major in math and computer science would be a good option for my tertiary studies, as, my passion lies in the Mathematical Sciences. However, I have not decided on...

What do Ph. D student's learn after a bachelors? I mean, I understand that a Ph. D is research oriented, but what do you learn, what would you research? I'm curious about the field and was wondering if there were any Computer Science Grads who could help me out with this, from a first hand...

Hi all, I was just wondering if you guys know of some good books that would show previous scientists lives and how they discovered what they did. I'm a huge Sir Isaac Newton fan especially, but it seems impossible to find anything on him? Also if it's not too much, could you list your...

I am trying to apply to colleges online to transfer to next year after I finish my AA. However, I am not sure if I am applying for a Bachelor of Arts or Science? I am a physics major looking to get my BA and then head on to grad school for my PhD. Not sure if that determines which I choose or...

Hello! Sorry, I'm not not exactly sure if this post is in the right thread. But I would just like to ask what time travel theory is appropriate, and hopefully much easier to use, for science fiction? I am planning to write a semi sci-fi short story, and it involves using time travel: to the...

I was wondering because I'm interested in getting a Materials science graduate degree, but was wondering if my options would be limited to experimental work. What sort of work would comp. materials science involve? My rough guess would be creating models/simulations of materials as opposed to...

Hey guys! I made an account finally, I've been on here forever, but it is finally time for me to ask this question now that I am in college... For a few years now, almost everyone I have talked to tells me that single majors in engineering are useless, and that double majors are the way to...

Homework Statement I have a project for my Materials Science and Engineering class and we have were given 4 unknown materials and we have to determine which kind of materials they are. We have to come up with our own experiments. As of now, I've done the Rockwell hardness test, electrical...

As not to derail the other thread where this is brought up. What are the odds of getting on tenure-track in an academic position in the sciences? I'm curious about both community college and state universities. I hear 1 in 100 a lot. In the recent thread here, the qualifier was...

I have the be careful because I don't want this topic to be about philosophy. I want to know what science thinks about consciousness. Is there a global agreement on what it might be? A physical thing like a gene or is it linked in with dna? There must be some kind of scientific view on what...

I have this one question. When you have Master's degree in mathematics, can you do a second Master's degree in computer science without doing the bachelor's degree in computer science first?

Hello everyone, I'm an undergraduate senior majoring in physics and math, with plans to go to grad school next year. I have two questions for you all: 1) for someone interested in nanotechnology, biotechnology, and physics, is materials science a good PhD to pursue? 2) If so, are there any...

Since I was little I wanted to be a scientist. Ultimately though, I was talked into going for engineering because the jobs are apparently so much better. Currently my major is electrical engineering and I'm interested in focusing on robotics. But there are parts of it I absolutely hate...

How would you relate computer science to analysis ( real and complex ) ?

I'm looking at some Materials Science graduate programs and some of the research areas involve simulation of material growth and properties. I'm kind of wondering what the value of this kind of research is as opposed to more practical research. This probably goes into the philosophy of science...

Which do you think would be more lucrative in the long run? I am in computer engineering, and I would like to do my own startup, but I am exploring other options as well.

I wonder if the German speaking members have recommendation to classic German textbooks or writings in Physics and Mathematics. I prefer undergraduate level but you can of course share other important works. I am also interested in learning German physics and mathematical terms since they have...

I can't get my head around it when theoretical physicists talk about types of branes and how these branes could be described in order to account for a cause of the initial creation event as it is now posited. It seems to me that because it is obvious that we will never be able to get enough...

I am trying to understand how our brain interprets sound and I am bumped on a few things. We can differentiate between different frequencies of sound (athough if they are close enough we might get confused). And there is something called pitch which is a subjective realisation of frequency of...

I went through someone's thread asking regarding a popular science book, a considerable time ago. I got the impression that the more knowledgeable members in the discussion did not approve of most popular science books (if my memory serves me right the point mainly was that it gave people the...

Hi, I love the cognitive sciences. Indeed, for the last few years, what's been motivating me to work hard in school has been almost exclusively my dream to lead a life deeply mired in the mysteries of the mind/brain. I haven't gone a waking hour in an extremely long time when I haven't thought...

Science fiction in my opinion means something scientific that isn't real (at the moment). Looking through history, star trek ect a lot of science fiction there has become a reality. I'm interested in hearing from people who teach / research physics if there was ever a time when something was...

So i love astronomy, physics, maths and cosmology. I want to bring this all together so i found a degree 'AstroPhysics", and it is something which i can do well in and enjoy. I'm wounding if i should go for this degree or go for an Advanced Science Degree major in Physics? So it is more of a...

There seem to be blogs popping up all over the place about women in science. They are a great idea. There is often a lack of science on such pages making it difficult to get a good picture of what women in science are actually doing. I am an accelerator physicist, at this moment working on...

a few days ago another member posted a thread about the Fox new report on a chunk of the sun flying towards Earth here's yet another news item one an Australian online news site... Sun's magnetic field about to flip Aug 07, 2013 8:34am NO, it doesn't happen every 11 years on and NO it...

Science isn't the kind of "circular dynamic" I thought it was. "Why the laws are as they are is a pretty easy question to answer." The statement above really bothers me. Why is C constant? Why does mass distort space-time? ... Experiment tells us what the laws are but experiments don't...

hello guys , i currently live in egypt , and i believe i will also be getting my college education in egypt * i am also a british citizen * the thing is , science here isn't really .. well promising i loved science since i was a child , always loved physics and atoms seemed to amuse me the...

I'm looking for a book that gives an explanation of why people behave differently in situations. It should describe different kind of behaviour people can have in circumstances. For eg: - In school some students become more popular, they stand up in class and everyone knows them while some are...

I think I received some wonky science, I need you folks to correct me. I'm going to try very hard to make this work. In fact I'm going to try so hard that I'm going to make up science as I go. I'll let you smart people figure out where I went wrong. So the basic idea is a 60' pipe going at an...

Crap. I couldn't get everything i wanted in my topic title. Anywho, I'm wondering which masters degree would be better for a career in machine learning / smart data while still keeping other - traditional options available? I would love to do a double major and earn both graduate degrees but...

Hi everybody, First, hi PF! It seems like there's a pretty wide array of backgrounds on the forums, so I'm hoping I can solicit a little advice. I recently graduated with an MS in Physical Chemistry from a top-ranked program. I passed my qualifying exam and everything, but decided that...

I for exemple am also a Manga otaku(japanese equivalent of geek) and also a fan Marvel comics,and I like certain kinds of music in some way...but Science and mathematics are still way up there ( number one in the list)...what about you what do you delight in doing?

''There are the rushing waves mountains of molecules each stupidly minding its own business trillions apart yet forming white surf in unison. Ages on ages before any eyes could see year after year thunderously pounding the shore as now. For whom, for what? On a dead planet with no...
