What programming language(s) should an aspiring physicist learn?

  1. Feb 1, 2009 #1
    I was surfing around the forum, and I noticed that several people recommended learning programming for physicists. What language is most useful for physicist? C? Fortran? Java?

    The most common language for the subfield you are interested in.

    If you are going to be working in a lot of fields using simulations or models the existing stuff is going to be written in Fortran or very Fortran-like 'C'.
    If you are starting from scratch, python (with numpy and scipy) is good, or if you are in a more theoretical area something like maple or mathematica.

    C plus plus

    Matlab/Simulink seem to be pretty big in physics and engineering. LabView is also extremely useful if you do experimental work.

    I would suggest C/C++. I found that learning this helped me when I was using Visual Basic for Applications, Matlab, PV-Wave etc.

    C/C++, Fortran and Matlab are the main ones.

    Java if you're considering working outside academia.

    Labview if you're suicidal and wish to learn the worst piece of software ever created by man.

    Well, I don't like Labview either; but it is still the de-facto standard for controlling small(ish) measurements setups and there is not like there is much choice if you e.g. want to control DAQs (I have used Labview on a daily basis for almost ten years). Not to mention the fact that it is the only software EVERYONE knows how to use (I would often prefer to e.g. use the Instrument Control Toolbox for Matlab; but most of my colleagues don't know how to use it)
    Also, Labview isn't a "normal" programming language and is pretty much useless for anything outside the lab so it is not something one would learn INSTEAD of e.g. Python. That said, if you know how to write simple programs in Python, C, Java etc you will be able to write Labview programs almost immediately.

    Hence, learning Labview is a good idea; but wait until you actually need it and learn another language first.

    I'm trying to convert everyone to using Matlab's instrument control toolbox instead of labview

    6 lines of code are much neater than 9 boxes and 21 arrows.

    I've been hopping between IDL and PERL for use in astronomy research. I guess I use a bit of C/C++ as well, but PERL is definitely what I use the most for right now.

    Python is a very powerful and easy to learn language.
  13. Feb 17, 2009 #12
    Python would be a great place to start.
  14. Feb 17, 2009 #13
    I'd recommend C++. You'll learn a very popular, powerful, and modern language and at the same time learn C into the bargain.

    Fortran 77 and 93 are still very popular with many researchers.

    Python is becoming the standard though for much of physics and it's much more powerful than MatLab users realise.

    I think this is the wrong question. You should learn to program, not learn a language.

    There are a lot of people that can cobble something together that runs. There are many fewer who can actually program.

    I recommend learning Mathematica, since it combines a general programming language with the most powerful symbolic system for doing algebra, calculus, visualizations, etc. It really saves a lot of time!

    I think Fortran is very easy to learn, it seemed the most "naturally English" to me. I also think Mathematica is a good program, it -really- helped me study for my math methods in physics courses.

    Thanks everyone.
    I just have another quick question. My school only offers C++ and java as intro computer science classes. In general, do people learn python, fortran, mathematica, etc. on their own, such as by reading books on the subject or by working in a lab?

    Introductory C++ and Java classes are a waste of time. They stretch a week's worth of material into a quarter/semester.

    You will probably pick up most languages as you study and work on projects.

    Haskell since it forces you to think mathematically.
