- Description: A well known fact about any work of art of any significance is its power to upset current conventions and disturb certain of our normal emotional patterns. The artist frequently achieves this by deliberately expressing emotions that are violent. There is nothing, however, new about the existence of violence in the arts, a large number of works in the history of art being painted with blood. One has only to think of the many battles, rapes, murders, martyrdoms and catastrophes that have been the subjects of many great paintings. Since the beginning of this century, and especially since the work of the Impressionists, in which violence is entirely excluded, violence has taken on a role of great importance and has been used to a greater or lesser extent by artists and group movements. It would appear initially that there are two main reasons in this century for the use of violence: one as a means of using it as a weapon against the academic and avant-garde in the arts, which in turn reflects attitudes found in society, and secondly as a direct reflection of the corrupt society in which we live. This is not to say that the twentieth century is an age in which more violence and sadism is found than in any other era of history, but never has it received so much publicity. I do not believe that man has change so much over the years, but it is my view that the apparent increase in this century is due to the vast changes in communications, it is due to the publicity it receives that violence has in recent times become a focal point, with murders, assassinations and war part of our daily lives. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 1971

- Description: This thesis describes the design and construction of a swept-frequency polarimeter for observing Jupiter’s decametric radiation in the frequency range from 15 to 45 MHz. The frequency band is tuned in two parts using two receivers for observing the left- and right-circular components of the radiation in the 15 to 26 MHz range and two receivers for observing the circular components in the 30 to 45 MHz range. The receivers are tuned electronically by means of varactor diodes and are of novel design in that they do not have any intermediate-frequency stages. The frequency band can be swept 10 times per second or 100 times per second. The antennas used for the polarimeter are helical beam antennas, two for each of the circular components in the 15 to 26 MHz range and two for the 30 to 45 MHz range. Model studies of the antennas were conducted to establish whether they have suitable characteristics for observing the polarisation of Jupiter’s decametric radiation over a wide frequency range. Many spectral records of Jupiter’s decametric radiation were obtained using a preliminary version of the swept-frequency receiver and a log-periodic dipole antenna. Some of the records are presented and one record which shows an interesting case of Faraday rotation is analysed. , Thesis (MSc) -- Faculty of Science, Physics, 1970

- Description: War is a condition of this world. From man to the smallest insect, all are at strife, yet man has a "quality which makes him overlord of all; for whereas the creatures of the forest and plain kill only to eat, or to lead the herd ... man will kill for no reason at all. This makes him terrible among the creatures, for he is the very God of Destruction. And from man's pride in his weapons that give him power has grown his art." Warfare in its primeval state is a direct result of a natural phenomenon, springing from the discovery that certain grass seeds could be cultivated and that certain grass feeding animals could be domesticated. From these roots sprouted two very differently organised communities, the agricultural and the pastoral, who clashed for the first time in the third millenium B.C. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 1968
