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 :)
7:50, flux is directly proportional to concentration gradient, not inversely.
Great video anyway!
according to the summary, its the Flus :)
This is excellent! Thank you.
u explain so well I recently fined ur channel but it's reallly good thanks A LOOTT
very well explained , thanks for sharing
This is very useful. Thank You
thank you for sharing. Good Explanation
It was nice.Can you share another one like this
thank you Dr Schamberger!
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.

This equation seems circular.
