PHYSICS AND MATHEMATICS OF STRINGS

EDITED BY SIR MICHAEL ATIYAH, F.R.S., J.R. ELLIS, F.R.S., M.B. GREEN, F.R.S. AND

C.H. LLEWELLYN-SMITH, F.R.S.

String theory apparently provides an appropriate framework for a 'theory of everything' unifying all the elementary particles and their interactions, solving problems of quantum gravity, and casting light on the origins of space and time. The two-day Discussion Meeting held at the Royal Society in December 1988 brought together many of the leading physicists and mathematicians active in string theory and related areas of mathematics. Fundamental issues in string theory were aired, mathematical tools were presented and questions raised, attempts were made to relate string theory to known particle physics, and connections with other areas of physics were discussed.

This volume brings together contribution by mathematicians as well as physicists, and provides an overview and insight into current developments into both the physical and mathematical aspects of string theory.

THE EARTH'S CLIMATE AND VARIABILITY OF THE SUN OVER

RECENT MILLENNIA: GEOPHYSICAL, ASTRONOMICAL, AND

ARCHAEOLOGICAL ASPECTS

Organized and edited by: J.-C. Pecker and S.K. Runcorn, F.R.S.

The calibration of 14C dating by dendrochronology has yielded evidence of an approximate 200-year period in the 14C

generation rate in the high atmosphere. Measurements of 10Be in ice cores have provided additional evidence for this variation in cosmic rays, which must be attributed to changes in the magnetic activity of the Sun. Historical observations also show such a modulation of the 11-year sunspot cycle with a similar period. Therefore, the question is whether variations in the total energy output of the Sun have had effects on the climate. Such variations are of increasing interest for archaeologists and historians. This new evidence is relevant to interpretating global temperature changes over the past 100 years and to discussions on the greenhouse effect.

The volumne contains the contributions to the Discussion Meeting held at the Royal Society in February 1989, organized jointly by the Academie des Sciences and the Royal Society. This historic meeting brought together physicists, geologists and archaeologists, and provided a forum where scientists working in many different areas could meet and exchange ideas.
