The nature of light was the subject of such controversy ever since two schools of thought - one led by Newton, the other by Huyghens - had proposed two different viewpoints of the nature of light. Newton viewed light as a stream of discrete particles while Huyghens maintained that light was a form of wave-motion. As any O-level student knows, experimentation involving wave-properties such as diffraction (the famous Young's slits experiments) eventually proved as correct Huyghens' idea of light as waves passing through a continium, which was eventually shown to be space itself by the Scot, James Clerk-MaxwelI in his work on electromagnetic radiation. By the end of the 19th Century, it seemed that light presented no problem. Light was waves.

First, the British, in complete control of the Mediterranean and engaged in empire building in Asia and Africa, brought previously unknown prosperity to these Islands especially to the middle-class merchants. This includes the relocation of holiday homes and a change in public transport which included Valletta-Sliema ferry service. The second factor was population over-spill from the Five Cities (Bormla, Birgu, L-Isla, Floriana and Valletta) from 1850 to 1950. The third and the last factor is that Sliema has become an important commercial centre expressed spatially by the multi-storey shop and office blocks.

It has been loved, fought for, mistreated land enjoyed by a succession of civilizations. It is annually invaded by millions of tourists (one-third of all international tourism) in search of fun, beauty and past glories. Moreover, the economic, social and political future of our islands is inseparable from this sea's future. And meanwhile, the Mediterranean has become the cesspool of its member states, a polluted body of water, waiting to be cleaned from a long list of major pollutants. Right on top of this black list, comes that dark fluid on which our modern society is so much dependent - oil. Though representing only 1% of our planet's ocean surface, the Mediterranean receives more than its fair share of global oil pollution. What are the likely causes which have led us to such a near-crisis situation? Mon, 01 Jan 1979 00:00:00 GMT https://www.um.edu.mt/library/oar/handle/123456789/20406 1979-01-01T00:00:00Z
