Diffusion: Fick's second law



9 comments:

  1. Creative way to describe flux. I think you did a good job overall describing concepts that perhaps not a lot of people are familiar with.

  2. How do you determine best fit for modeled diffusion versus measured data?

  3. I am not sure about your second diagram for explaining diffusivity. Its a bit difficult to relate to what your topic is, at least from what you explained.

  4. I really liked the cookie analogy. You explained the concept simply and it was easy to follow your presentation.

  5. What's a flux? You defined a term with another term people may not know. I would've understood better with cupcakes. Or if you had brought in cookies.

  6. Good, clear presentation, just a little laser-pointer happy. The cookie analogy was also great. Your discussion of uncertainty was also nicely done.

  7. I like the baking analogy. The equation is well explained for both of the time and distance scale. You answer the question about equilibrium very well. Good job!
