    Blackboards vs. Whiteboards: A Scientist's Perspective

    Blackboard by far. I don't think I have ever seen a whiteboard without stuff permanently written on it.

    Why normalize equations when solving numerically?

    In most textbooks I've read and programs I've work with, differential equations are normalized (made dimensionless) before being solved with some numerical method. What is the point of this? It's seems to be a lot of work for no benefice. So, after a lot of derivations, you end up with some...

    Ok to delete the registry from windows computer

    He was messing with you. I would not even try to clean it either. You wouldn't notice any speed improvement anyway and you run the risk of seriously messing up your computer. Leave the registry alone.

    Lingusitics Do you think the portuguese language a romantic language?

    I'm a Québecois and I've heard a-ou, ou and oute. I would say 'ou' is the most common pronunciation here. When you said 'out' I thought you meant 'oute', like in the examples you posted.

    Lingusitics Do you think the portuguese language a romantic language?

    There are three different ways to pronounce août that I commonly hear and "out" is one of them.

    Cross product of complex vectors

    How is computed the cross product of complex vectors? Let ##\mathbf{a}## and ##\mathbf{b}## be two vectors, each having complex components. $$\mathbf{a} = a_x \mathbf{\hat{x}} + a_y \mathbf{\hat{y}} + a_z \mathbf{\hat{z}}$$ $$\mathbf{b} = b_x \mathbf{\hat{x}} + b_y \mathbf{\hat{y}} + b_z...

    Fortran Problem setting integer precision in Fortran

    Thanks for the reply. I don't think that's the reason however. If I understand correctly, [FONT="Courier New"]selected_int_kind(n) returns the number of bytes (not bits) needed to hold a number with n digits. For example, this code: program prob003 implicit none integer...

    Fortran Problem setting integer precision in Fortran

    I'm trying to work with big integers but for some reason this program won't compile: program prob003 implicit none integer, parameter :: k32 = selected_int_kind(32) integer(kind=k32) :: num = 600851475143 end program prob003 The file name is prob003.f90 and I'm trying to...

    Computational physics specialization

    I really like all (most) fields of physics and I find it hard to choose a specialization for my master's and eventually my career. Is it possible to specialize in computational physics so that I could work in many different fields?

    How did you discover Physics Forums

    I was searching for a science related forum. As a physics major, I must say I'm very satisfied with what I have found. :)
