An additional benefit of Joshua's post, over and above its own merit, is that if gives me a new resource. The next time someone complains: "Cassius your posts are always too technical - I just want advice on being happy." I will say in response, "Check out the post entitled "Potential Hydrocarbons in the Constellation Leo."

And I will say: Man, you don't know what it means to be truly happy unless you understand the implications of hydrocarbons on other planets!"

PD12. A man cannot dispel his fear about the most important matters if he does not know what is the nature of the universe, but suspects the truth of some mythical story. So that, without natural science, it is not possible to attain our pleasures unalloyed.

And I will remind them too that Cicero writes that nature was Epicurus' "chief boast" ("‘At the outset, said I, ‘in natural science, which is his chief boast, he is in the first place altogether unoriginal...)

As usual, lots of caution, but this is an interesting recent article on one particular target of interest:
