Show Chart Changes In Heat of Sun Scientists Scientist Make Analysis Of Data Gathered Over Year 15 Period WASHINGTON Seven Seven radiation pulsations of t the sun have been confirm con cone firmed firm cd by Harvard university math maUl mathematicians who have completed a rigid mathematical analysis of data dala gathered by the Smithsonian In Institution In over 15 years f Measurements with delicate In Instruments In on cloudless mountaintops mountaintops mountain mountaintops tops scattered over the earth for the thelast thelast thelast last 20 years have shown that the tho solar heat received at the outer edge of the earths earth's atmosphere varies from day to day The sun upon whose radiation all life depends is I. isa isa a variable star The Increases and decreases however how ever were Interwoven Into an almost al ale most Inextricable pattern Sometimes Sometimes Some Some- times the peaks of ot two or more coincided and sometimes several depressions came together Several years ago ogo Dr Charles O. O Abbot secretary of ot the Smithsonian institution institution found by splitting up the total curve of ot othe the he suns sun's radiation that it consisted t of 12 2 subsidiary b I n con a ft L. L laws I u. u common denominator of ot approximately matey 23 years That is every 23 years the star went through a complete complete com pulsation cycle Some Statistical Illusions The analysis however was extremely extremely ex ex- difficult Some of ot the radiation radiation ra ra- differences in so far tar as they could be detected by any instruments instruments ments miles away were very minute All the complex effects effects ef ef- ef of ot passage through the earths earth's atmosphere on solar radiation had to be discounted There was at least a possibility that some of the he apparent pulsations were statistical illusions difficult to recognize Dr Theodore E. E Sterne of ot Haryard Harvard Har vard yard university undertook with the aid of ot his graduate students to analyze the data by a different more laborious and more rigid mathematical math proc procedure dure A mathematician clan cian familiar with the pitfalls of ot statistical sta illusion Dr Sterne approached approached ap ap- ap the problem with an objectively objectively ob ob- skeptical attitude Only 10 lOot of the 12 proposed proposed pro pro- posed by Dr Abbot were susceptible to the method of ot analysis used by bythe bythe bythe the Harvard mathematicians Out of ot these 10 his work shows seven are certainly real and must be con considered probably as actual happenings happen ings on the sun although the mathematics mathematics mathe matics merely shows that hat they exist and offers no explanation of ot them The Real The Smithsonian observations show he says that the periods of ot 9 11 21 25 39 46 40 and 68 months must be considered as actualities That is every 9 months the suns sun's heat for far some same unknown cause seems to rise to a certain cattalo peak and then decline Every 11 months there is a similar rise and decline The same is true for tor the other five Each period may have a different solar cause If U they all aU started together to toe and gather gether and presumably they did in inthe inthe the beginning they beginning they all would approximately ap ape proximately coincide at the end o of 23 years Their complex combinations combinations would bring into the record many features of increases In the suns iun's heat with associated declines This period of ot 23 years is about double the he period of ot the sunspot cycle when titanic whirlwinds Inthe in inthe inthe the solar atmosphere go through a a maximum and minimum in frequency fre fre- quency These solar Dr Abbot Ab bot bat believes are a major element in the ear earths earth's weather although the relationship Is very complicated The Tho independent confirmation of ot seven of ot them affords a substantial basis for further studies in this field |
