A few comments first on education in schools - this is a special worry here in the UK, where our international rankings are disappointing. An appreciation of science is vital not just for tomorrow's scientist and engineers, but for everyone who will live and work in a world even more underpinned by technology - and even more vulnerable to its failures and misapplications - than the present one. Even more important, the option of higher education in science and technology should not be foreclosed to them. There is widespread concern particularly about the 16-18 age group. Many of us put strong emphasis on broadening the curriculum for this group, which currently enforces unduly early specialisation here in England. Young people opting for humanities should not drop all science when they are 16.
