Dr May I presume?

Congratulations to Brian May on passing his viva voce today.
There are many PhD students who start studying, move to part time and take on a job. And before they know it, the part completed thesis ends up in the loft, never to see the light of day again.
Brian is in a very lucky position whereby the day job has been done, and he can go back to his research. Fortunately, in the 36 years its been sat waiting, no one else has come along and either invalidated the findings, or done exactly the same thing so that his thesis remains a novel piece of research work.
I hope that he does go on carry out more research, but also plows time into encouraging others to consider science, and reminds all those people with half written theses that they could blow the dust off and finish the last chapters.
