Like.
There's an element of subjectivity in the quality of the book. I aways suggest, if you have a chance, drop by a bookstore* , or school... -
Mmathwonk reacted to lavinia's post in the thread Undergrad About the definition of topological manifold using closed sets with Like.
A way to construct topological manifolds from closed subsets of Euclidean space is through triangulations. For example, one can imagine...

Mmathwonk replied to the thread Other What are some good books for learning Galois Theory?.In terms of quality of exposition versus price, there can perhaps be nothing to match the great, but succinct and theoretical, treatment...

Mmathwonk replied to the thread Other Complex analysis or calculus?.The good news is: once one appreciates the need for a Riemann sum type definition of a complex path integral, it is possible then to use...

Mmathwonk replied to the thread Why do we spend so little time learning grammar in college?.In my case, "I am older than dirt" seems more accurate, (or for purists, perhaps "I am older than dirt is"?) But probably both make the...

Mmathwonk reacted to pasmith's post in the thread Graduate How to Find Critical Points of function f(x,y,z) with Like.
There is a fundamental problem here: \nabla \times (y + 5, 2z, y) = (-1,0,-1) is not zero, so (y + 5, 2z, y) cannot be the gradient of a...
