| Apr 10, 2010 at 1:14 | comment | added | Steve Huntsman | I use de Rham (co)homology as the yardstick for my intuition. It tells me that homology about stuff that you integrate over. Cohomology is about stuff that you integrate. See also here: en.wikipedia.org/wiki/De_Rham_cohomology#De_Rham.27s_theorem | |
