of cosmic rays
Royal Society's premier lecture in the physical sciences,
the Royal Bakerian Lecture, is to be given at Leeds by
former Astronomer Royal Sir Arnold Wolfendale, on cosmic
rays, what they are and where they come from.
Arnold Wolfendale has been a fellow of the Royal Society
for 25 years and has had a lifelong interest in cosmic
rays, which are the nuclei of atoms accelerated to high
energies in, as yet unidentified, parts of the Universe.
They have been raining down on the earth for millions
of years, and although human beings are biologically adapted
to withstand them, they are thought to have an impact
on climate change.
lecture will cover many aspects of the search for the
origin of cosmic rays and is designed to be accessible
even to a non-scientific audience.
in 1912, the so-called cosmic radiation comprises particles
of energy up to the highest known to mankind. Even at
low energies, however, their origin is subject to doubt
and the higher one goes in energy the more uncertain their
origin becomes, and the more problematical the particle
masses. Sir Arnold Wolfendale will assess the situation
and provide answers based on his own analyses.
Professor Sir Alan Wilson will chair the lecture, which
takes place on Thursday 14 February at 5.30pm in the Rupert
Beckett Lecture Theatre at the University. Admission is
free and no advance booking is required. For further information,
