    7:50, flux is directly proportional to concentration gradient, not inversely.
    Great video anyway!

      according to the summary, its the Flus :)

    why there is negative sign in fick's law. J=-D(slope)

      Osama Ahmad it represents that the diffusion occurs down the concentration gradient

    6:10 Letter "J" or Sigma ? im confused :)
    just kidding !!! i love the videos thx you very much

    uhh.. your playlist is playing backwards.

    Really nice, except:
    1. flux is the CHANGE in mass, or mass that moves from one side to the other (delta mass, if you will) in a fixed period of time (or a unit of time, or again delta time), which together would be the flow rate, through an area.
    2. Fick's law of diffusion (nor any other physical law for that matter) does not "control" any physical process. The "laws" are just models that with some level of accuracy describe the process in quantitative manner.
    3. What your animation presents is in fact non-steady diffusion process that cannot be described with the first Fick's law. You just magically freeze it at some stage to pretend it is steady for that magical point of time. Not fair, not fair, sir

    This equation seems circular.
