Half of the country’s leading researchers were educated in private schools — 7% of the total population. About 10% of the state secondary schools that take science seriously comprise the rest. Thus we waste four-fifths of the potential scientific talent who are frustrated by a lack of adequate science teaching. This is why the government is now beginning to take science teaching seriously for the first time in 150 years. If we don’t, then we won’t remain an advanced country for much longer.
