8.30 Research Report: 11: Seeing in the Dark
A series of eleven programmes looking into current research on the frontiers of science

Our eyes are sensitive to only a narrow band of frequencies in the broad spectrum of electro-magnetic radiations. When these frequencies, which we call light, are absent we cannot see; but even on the darkest night the earth is bathed in infrared radiations which, if we could convert them to frequencies which are visible, would be almost as useful to us as moonlight. An exciting and important advance has recently been made in this field at the Signals Research and Development Establishment, Christchurch.

9.0 Age of Adjustment: 6: Britain as a World Power
A series of six programmes on British foreign policies from 1945 to the present day.
Presented by Peter Calvocoressi, member of the Council of the Royal Institute of International Affairs.

Those taking part: Leonard Beaton, Senior Research Associate, Institute for Strategic Studies; The Rt. Hon. Kenneth Younger, Director of Chatham House.
