' Studying Cosmic Rays '
P. M. S. BLACKETT , F.R.S.
(Professor of Physics, Birkbeck College,
University of London)
Tonight Professor Blackett, Professor of Physics at the Birkbeck College, University of London, since 1933, is to give a talk on a subject which for thirty-three years has occupied hundreds of research workers all over the world. Cosmic rays are radiations having a shorter wavelength and greater penetrative power than any previously investigated, and so called because their source appears to be interstellar spaces.
Our ignorance about them is still tremendous, but what has been discovered is enthralling enough. It appears that the earth is bombarded in all directions by atomic particles. Where do they come from ? We do not know. How are they produced ? We know still less. Listeners are to hear all that is known about them, and just why they are interesting scientists everywhere.
