New Universe Ctiontrinzzed from Page 32, This work created a sensation among physic- ists, particularly among those who could not understand it, indeed, the chief drawback of the theory is the difficulty of expressing it in- telligibly. And these difficulties were increased by the radical nature of the hypothesis itself. Einstein argues that the much-discussed absolute motion has no physical significance, that only motion of one body relative to another has any meaning. He discards entirely our notions of time and space, say- ing that the former is dependent on motion and that two events that appear simultaneous to one observer will not appear so to another with a different motion. The year before publishing this paper Einstein had been married, and in 1909 he resigned his patent ofiice duties and accepted a professorship in the Zurich Academy. It appeared as though he might now settle down and enjoy a well-earned life of ease, but instead he continued to labour on his Theory, which he felt was incomplete. Newton had shown the relation between the mechanical laws of nature and the observer's motion, Einstein had exe tended this to include optical and electrical pheno- mena as well, and it now occurred to him that his conceptions might hold good for any form of motion whatsoever. Ten years he laboured, and in 1915 appeared his crowning achievment, the General Theory of Relativity. In it he showed that time and space are one and inseparable, and managed to ex- plain the phenomenon of gravitation for the first time. And among other things he stated that light rays are subject to gravity, and are bent in passing close to a large, massive body such as the sun. Here, at last, was an opportunity to lift this hypothesis from the realm of the abstract into that of the concrete. An eclipse of the sun was needed, and in 1919 there occurred one that was so fortunate that it seemed to have happened on purpose. A British expedition was sent to Sobral, in Brazil, and returned with the first definite proof of the Einstein Theory. The method was somewhat as follows: During an eclipse, owing to the darkening of the landscape, the stars shine out although the sun is in the sky. And in May, 1919, the sun was eclipsed near two very bright stars. The scientists measured the apparent distance separating these stars, Ein- stein held that the proximity of the sun would cause a bending of their light rays, so that the stars would appear farther apart than they would six months later, when the sun was nowhere near. He calculated the displacement that should occur, and then the scientists measured it. The two results were in exact agreement, and the theory had triumphed! Later came another test of the hypothesis, when Einstein was able to explain a mysterious shifting of the orbit of the planet Mercury, which no one had previously been able to explain. Most scientists to-day accept the Theory of Relativity, with its revolutionary conceptions of the universe.

The man who gave it to the world is now working on a General Field Theory which he believes will be the greatest of all his triumphs. Whether or not his most splendid contribution to science is still to be made, the work he has already done suffices to establish Albert Einstein as one of the greatest of scientific leaders, one of the supreme geniuses in the history of thought.

When We go out on deck to take some pictures, it is necessary to put on our heavy coats. This glacier has its source in an immense ice field from which several other glaciers originate. It is about three miles wide at its mouth, two hundred feet high, and extends back for thirty miles. This is a live glacier and sometimes thrills the traveller for the blast of the ship's whistle may cause large pieces of the ice to break off. From Taku it is a short run to our next stop- Juneau, the capital of Alaska. Juneau is a small but prosperous town. It is the home of the Juneau Alaska Gold Mine which is one of the greatest gold mines in the world. There is a fine museum in Juneau which contains many Indian, Russian and Eskimo relics. The major attraction is, however, Mendenhall Glacier which can be reached by bus from Juneau. This trip is very popular because one may go right up to and in some places even onto the glacier itself. The last lap of our northern voyage is through the beautiful Lynn Canal. High mountains rise abrupt- ly on either side and on their peaks can be seen traces of ancient glaciers. In a little while we reach Skagway-the point where the Trail of '98 be- gms. Skagway is an Indian name meaning Horne of the north wind. But it might well be called the Flower City of Alaska, due to the size and variety of plant life. Here we find dahlias fourteen inches across and pansies four inches in diameter and sweet- peas growing on vines eight to ten feet high. These may appear to be exaggerated but in reality scarcely do justice to the beauty and size of the blooms. At Skagway we visit the grave of Soapy Smith, a notorious gambler who lived in the wild days of '98, Our guide happens to be a very great friend of Soapy's who has refoimed and now runs a home- made street-car for sightseers. Martin Itjen is very proud of his old acquaintance and delights to take the crowds of people into the old, boarded-up gambling parlours and through the now deserted streets of Skagway. This is truly the Land of the Midnight Sun. At eleven forty-five o'clock at night, it is still light enough to take a picture and daylight comes again very early in the morning. In all there are only three hours of semi-darkness. Mr. Barnforth: Did you say this was to be a dangerous operation? Doctor: I'm sorry, but if you want something with risk to it, you'll certainly have to pay more money. John Hooper: Mother, there must be something wrong with this hot-water bottle. . Mrs. Hooper: What do you mean. John: Well I put some water in it yesterday and it's not hot yet.
