Science Advances LongDistance Radio

Received Friday, 8.50 p.m. LONDON, August 10. Data obtained at the time of the eclipse of the sun on July 9 will advance “optimum wavelength forecasting.” Sir Edward Appleton has declared that he is the discoverer of a 130-mile high “radio” layer named after him. This new subject worked on throughout the war has resulted in improved long-distance radio communication. He said there was now a world survey in progress of the electrical strength of the Appleton and Heaviside layers. The Empire is collaborating in making measurements of electrical strength over certain places. In particular,

Great Britain, India, Canada, New Zealand and Australia are taking part. Sir Edward Appleton said: “We now know so much about the reflection power of these layers that we know they vary from day to night, from month to month and from year to year. We can now predict the" best wavelengtbs to use months in advance to get the best reflections. In the past year, for example, one wavelength would be optimum and in another year the optimum value would be different.”

Attention is drawn to an advertisement in this paper referring to Tuesday evening’s function to men on leave, which is being held in the Opera House at 7.30 p.m. The public are cordially invited to the function and it is naturally anticipated that a large crowd will be present to give the men the accord they so w r ell deserve. Men from the city and surrounding districts who are on leave are extended a cordial invitation to attend.
