    Software to simulate an atom and chemical reactions?

    Hi, I am trying to simulate in 3D a bunch of chemical reactions. Some of them are complex and I would like to be able to just spawn the elements and molecules and watch them collide to see what happens. Is their any free software to do this?

    How intimately can we observe DNA replication?

    I found this interesting computer animation representing DNA functions in cells. My questions: 1) How precisely can we actually magnify cell functions, and what is preventing us from peering in as closely as depicted in the video (keeping in mind that I know it's probably technologically...

    Normal electric field across the interface

    Dear all: The boundary condition of electric field is well know for us which illustrates that the normal component of the electric field will not be continuous across the interface between 2 dielectric material with different dielectric functions. (There is no extra fixed charge on the...

    How can you tell if a molecule is polar or nonpolar

    Hello, for octane (C8H18), how can you tell whether or not it is polar or non-polar without drawing a lewis structure diagram? also, if you absolutely need to draw one, what is the easiest way to go about drawing a more advanced molecule like octane? I can draw simple molecules and find their...
