WHEN John I. Snyder Jr. flew over from the United States he probably did not relish the Cassandra rôle into which circumstances had forced him. As president of U.S. Industries he gave one of the most depressing addresses of modern times. Since his firm is a large manufacturer of automation machines it was probably natural that he should say: ‘Automation is inevitable. Its use is rapidly increasing. Positive action by the makers of automation machines must be taken now to preserve the human values which could otherwise become cannon fodder of the automation barrage.’

ONE of the problems which have to be solved in the immediate future concerns the increasing percentage of sulphur present in diesel fuel oil. A paper recently presented to the Diesel Engine Users Association by C. G. Williams, D.Sc., M.I.Mech.E., F.R.Ae.S., F.Inst.Pet. and A.

The paper was entitled “Diesel Fuel Research at Thornton Research Centre” and referred, inter alia, to the ill effects of sulphur in fuel oil and the efforts being made to counteract them.

THE emergence of the digital computer has revolutionised the Engineering Science in every major discipline and industry during the past fifteen years.

NOWADAYS one tends to associate the terra statistics entirely with numeration and mathematical analysis. It is perhaps of some interest therefore that when the term was first used in 1770 it was defined as ‘The science of the political arrangement of all the modern states of the known world’. Later (in 1787) it was related to the science of ‘the power of the several modern states arising from their natural advantages, industry, etc.’
