Is it time to change the undergraduate curriculum?

Charles Day:

My two oldest nieces, Miriam and Sarah, are both 16. Later this year, they will start their respective searches for a place at college in earnest. Their experiences will be different, not just because Miriam is interested in science and Sarah is interested in teaching. Miriam lives in Conwy, an ancient town of 15 000 people in North Wales. Sarah lives in Olney, a Maryland suburb of 34 000 outside Washington, DC.
When it comes to undergraduates, the university systems of the UK and the US are significantly different. In the UK, students typically study just one subject for three years—physics, in my case. In the US, students spend less time studying a major; more on other subjects.
