The Hebrew University of Jerusalem has published more than a hundred new manuscripts of Albert Einstein. Most of these have never been seen before.
The university has arranged to display more than 110 manuscripts on the occasion of the 140th birth anniversary of this famous scientist.
The collection also includes works by the Nobel laureate that have never been published or researched before.
These were purchased from the personal collection of a man in North Carolina. The Crown-Godman Family Foundation also provided some.
The manuscript also contains an appendix to Einstein's essay on unified theory, which has not been seen anywhere since the 1930s. He spent three decades explaining all the concepts of energy in a single theory.
Earlier, the university had assumed that an appendix to his writing had been lost.
Einstein admitted in a message to his fellow scientist Michelle Besso that even after 50 years of pursuit, he did not understand the quantum type of light
