- | <note tip> | + | Differential forms (co-vectors) are functions (elements of dual vector-space) which map vectors to real numbers. |
- | In this section things should be explained by analogy and with pictures and, if necessary, some formulas. | + | |

+ | * Vector Calculus, Linear Algebra, and Differential Forms: A Unified Approach by John H. Hubbard and Barbara Burke Hubbard - Extremely student friendly, lots of margin notes that talk about the "soft" stuff that's so crucial to the actual practice of math. Reading just the margins jumps your mathematical maturity by 2 years. | ||
+ | * Another good introduction can be found in “Visual Differential Geometry and Forms: A Mathematical Drama in Five Acts”(2021) by Tristan Needham | ||
