Interpolation 2D (a) a sentence or two describing the circular fields that are involved. (?magnetic fields from a wire?) (b) a color bar for the first two images? That will...

Discretize: Examples **(THIS ERROR WAS FIXED)**: Cahn-Hilliard: tex equations are not rendering Stream Line thickness: The color image is washed out and thereby the example loses impact. What is the...

**Differential Operators (THIS TYPO WAS FIXED)** Overall: This is really(!) well done. Congrats! Main point: With each of the discretizations of Div, Grad, Curl after you have shown that you...

**Interpolation (THIS FIGURE WAS FIXED)** have 9 nodes but plot seems only to go to 8 

**Interpolation** Having distinct sections for nodal and cell centers seems to make the problem more complicated than might be needed. What about saying that the function to be interpolated is...

Is there a sentence missing?  Also the term "Averaging Matrices" is commonly used and we should keep that and the symbol A. However, these are really interpolation matrices and...

It worthwhile having a discussion about a uniform notation so that we keep nodes, cell centers, widths of cells, and widths between cell centers as unambiguous as possible and uniform...

**(LINK WAS ADDED FOR KRONECKER PRODUCT)** I think this is the first time that Kronecker product has been used. ?? Wikepedia referrence? Going to 2D and working with the Kronecker...
