These papers have been found by Rowdy Boeynik, who is a student in the University of the Netherlands. While doing his research, Towdy Boeynik chanced upon some papers possessed by the family of an old friend of Einstein. These hand written papers is a set of 16 pages and has signature of Einstein at the end of the document.Â
In these papers Einstein has described behaviour of atom at low temperature. This is one of his last works in field of physics. These days this theory is known as Bose-Einstein theory.
Initially nobody believed that this manuscript was written by Einstein. Hence it was sent to forensic laboratory which confirmed that the manuscript had finger prints of Einstein. It has now been decided that the manuscript would be kept at Leyden University where Einstein was awarded the Nobel Prize.
