Though hundreds of thousands had done their very best to disfigure the small piece of land on which they were crowded together, by paving the ground with stones, scraping away every vestige of vegetation, cutting down the trees, turning away birds and beasts, and filling the air with the smoke of naphtha and coal, still spring was spring, even in the town.

comment Careers advice for Ph.D.s without current postdocs or university jobs
@Pete: This does not make sense; someone more experienced is not entitled to provided more accurate information than someone inexperienced but can give the right advice. I consider the fact I was an undergraduate in a liberal arts colleges to be an advantage, not the reverse. It is two years now, and I still think my advice makes a lot of sense to someone in Dr H's position.

You mean simple ones, or any? I did read Bott's collective papers but never seen this theorem. I shall check the link.
