Actually, I don't have a vocation, I fell into teaching. If there were more maths and physics graduates competing for these top-end jobs, then I'm sure more of them would fall into teaching too. Some of them might even like it.
I'm not suggesting forcing people to study maths and physics at Uni against their will. But more could be done to encourage them. If you look at the graphs, historically way more people elected to study them. Numbers fell dramatically and are only starting to recover. I doubt that there were more people with a vocation for maths and physics in the past.
"A University of Buckingham, UK, study indicates that the number of ‘A’ level exam entries in physics has halved since 1982. As a consequence, since 1994, a quarter of universities which had significant numbers studying physics have stopped teaching the subject.
This year, although 2006 ‘A’ level entries for all subjects increased by 2.8% compared with 2005, physics entries reached a new low with 2.7% fewer UK students. This hardly seems compatible with the Government’s target to increase, on 2005 figures, the number of students in England taking ‘A’ level physics to 45.3% by 2014.
Chemistry did rather better with a 3.1% increase over last year, but it is still 9.1% lower than in 1991. Mathematics and further mathematics recorded increases of 7.5% compared to 2005, but remained 4.5% down on 2001, when the substantial drop in student numbers caused by the restructuring of ‘A’ levels resulted in many students taking ‘A/S’ level mathematics but not continuing to the full ‘A’ level (a good illustration of how well-intentioned innovations can have unwelcome outcomes)."

I think that Brian Cox has led a renewed interest in physics and an increased uptake. Someone similarly inspiring could spur girls on to select it, perhaps, without forcing anyone to do anything.
