Dec 24 comment Shape of snowflakes It's not the same as assuming no molecules attach at the same time, because in your random model you're effectively adjusting the probability of attachment based on the size of the snowflake. If anything, you want to adjust the probabilities based on the geometry --- I would guess that available vertices deep "inside" the snowflake would have lower probabilities of attachment. Dec 24 comment Shape of snowflakes I don't like your random model: it seems much more reasonable to fix a probability p and at time t, attach a new hexagon at every available lattice point with probability p. Assuming a fair amount of water in the air, water crystallizing at one vertex should be independent of water crystallizing at other vertices (to a first approximation).

Don't these all illustrate the differences between real and complex manifolds, rather than between real manifolds and smooth complex varieties? Apr 25 awarded Organizer Apr 25 revised triangulations of torus, general, and Euler number. (Hopefully more interesting/relevant) edited tags Mar 21 comment Chinese Remainder Theorem for rings: why not for modules? Tensor the map $R/(I_1...I_n)\rightarrow R/I_1\times...\times R_I_n$ over $R$ with $A$. Feb 23 awarded Fanatic Feb 15 comment visualizing what's going on in based homotopy theory, et al. For c), have you looked at chapter 4 of Hatcher's book? Everything there is very geometric.
