Mr. Ghost. I newedana posted for the problem you raised on April 25, 6:06 in the topic of sci. physics: physical basis for melting-points of allots? You may find how beautifully your question was explained in the post. This problem is almost impossible to explain with established science knowledge. If you want to know more you can read Dr. Yoon's textbook(www.yoonsatom.net). I am sure his book is now available in the University Library of Chicago, MIT, Stanford, Oxford, Cambridge, Berlin, and Congress Library of the USA. So you can read his book without buying it. newedana
