Last year, astronomers announced the discovery of a new class of heavenly body-the' quasi-stellar objects,' or ' quasars.' This discovery came at a time when there were already certain trends in astrophysics towards a rethinking of fundamental physical laws; and it has led to claims that we need ' new kind of physics ' to explain the observations.
This evening three programmes which review the situation are being re-broadcast.
1: Quasars by DENNIS SCIAMA of the Department of Applied Mathematics,
University of Cambridge
Dr. Sciama explains some of the theoretical difficulties which arise from the discovery of quasi-stellar objects.
Second broadcast: previously broadcast in the ' Night Sky In the Third Network
This series of talks is now available as a BBC booklet and can be obtained by sending a cheque or crossed postal order for 3s. to BBC Publications. [address removed]. or by ordering through your bookseller.
