Wireless Radio in 1924

Posted June 12, 2014 by admin with No Comments in Science

WIRELESS offers more scope for enjoyment than any other hobby. This is a big claim, but any one who has cultivated wireless knows that it is a claim that can be supported by facts. The one outstanding feature of wireless as a hobby is that it can be pursued anywhere, at any time. In dry summer weather or in the depths of winter, in brilliant daylight or in utter darkness, in the privacy of your own den or in the heart of the country, you can rig up your wireless equipment and listen to messages from the most distant corners of the earth. You can make a portable wireless receiver which will fit comfortably into quite a small box and …

The Early Days of Television

Posted April 28, 2014 by admin with No Comments in Science

Television was first demonstrated in 1926 but at a much lower resolution than we use today. Early experimenters even recorded television onto discs, of which a small number have survived down to the present – and we thought that video discs were a much more modern invention! The latest addition to our web-site is an information page on early television or “seeing from a distance”. You can find out more on early TV here  

What is Dry Ice

Dry ice has already become a valuable refrigerant, and the reason is that its temperature stands some 112 below zero. Pound for pound it refrigerates fifteen times as much as common frozen water.

Atomic Energy

Posted March 3, 2014 by admin with No Comments in Science

Scientific thinking on Atomic Energy in 1929 A fond dream of scientists – the hope of some day obtaining energy in tremendous quantities by releasing forces known to exist within the atoms of matter – was given a Christian burial on the recent occasion of the award to the scientists Michelson and Millikan of the gold medal of the Society of Arts and Sciences in New York. To quote from Dr Millikan’s address, “There is no appreciable energy available to tap through atomic disintegration.” Every one who reads popular articles about science is familiar with the statement that there is enough energy in the atoms contained in a single dime to drive the Leviathon to Europe and back, if we …

Synthetic Sunshine

Posted January 14, 2014 by admin with No Comments in Science

THE world need never go hungry as long as the sun shines. So the chemists have declared at the Institute of Politics, at Williamstown, Massachusetts; and since scientists say so, it must be so. Food in the future, it appears, is to be obtained from the light of the sun and the nitrogen of the air. Proteins and carbohydrates-those elements of nutrition which you hardly can escape getting in a good dinner whether you like them or not-will probaly be made in the factory rather than raised on the farm. “Thirty men in a factory the size of a city block can produce in the form of yeast as much food value as 1,000 men working on 75,000 acres under …

Tidal Waves 1925

Posted December 24, 2013 by admin with No Comments in Science

A STUDY OF TIDAL-WAVES by Professor Vaillaux, a French authority, is given in The World’s Health, the organ of the International Red Cross (Paris). Says this writer: The determination of the causes of this phenomenon, which often produces terrible loss of life and property, is especially difficult in view of the difficulties of observation. Testimony of witnesses who have escaped from the calamity is natu­rally confused or contradictory. The seismograph and the barometer are the only instruments of value for scientific records, and the former can not function, of course, when earth tremors are absent.  Observations from boats at sea are almost always useless because of the relatively calm rise and fall of the ocean-level as the tidal-wave passes. The …
