your rays and focus them on one point. Isaac Newton LITTLE 

 could do it. " On a winter day I took a small glass and JOURNEYS 

 so centered the sun's rays that I burned a hole in my 

 coat," he wrote in his subsizar journal. 

 The youth possessed an imperturbable coolness he

 ematical genius work in this way and in practical life
