  • My N-body code sucks ass

    Apparently gravity no longer exists.

      What the hell is a N-body code?
      Why can't you be a non-conformist just like everybody else?

        You're ready for Skunk works
        What?

          Probably a program to solve the N-body problem for gravity, silly.

          Congrats on defeating gravity! Now you can do anything!

            It's a computer program for simulating the behaviour of a large system of coupled particles.

            In this case, it's to simulate the growth of large scale structure in the Universe, so the "particles" are galaxy clusters and the the coupling is gravity

              Unfortunately, my particles don't appear to be coupling. They're just sort of sitting there.

              Maybe I should tweak the initial conditions to provide greater deviation from uniform distribution than currently.

                  Cool. I thought "N-body" was some sort of sucky brand name like N-gage.

                  Luckily, I don't do computational physics, so I can't help you there.

                    If you plan to go to graduate school and become a theorist then you will be doing computational physics.

                    Everybody except a small number of experimentalists does computational stuff (or has their graduate students do it for them)

                      Bah. I wish more physics problems had exact solutions.

                            Did you use periodic boundary conditions?
