Note on travel

Learning about the Universe at the expense of damaging the one good spot we've found in it, I think, defies the point. For this reason, since my move to the US, I have offset carbon emission of all work related air travel. This expense cannot currently be paid for from official travel funds (which I think it should), so I have used my personal money to do so.
