It was a simple mathematical formula that changed the world forever and transformed our understanding of the universe. Now the very note on which Albert Einstein scribbled the revolutionary E=MC2 equation has been put on public display for the first time as part of a major online digital archive, Daily Mail says.

But the amazing collection of documents uploaded does not just include the genius' thoughts on the fundamental laws of physics. It also features revealing personal documents, including his wedding announcement, a letter in which he proposes a way to solve the Jewish-Arab conflict – and even a cheeky note from a six-year-old schoolgirl telling the renowned mathematician to get a hair cut.

Einstein, who died in 1955, bequeathed his papers to the Hebrew University of Jerusalem, which he co-founded.

The entire archive holds more than 80,000 documents but the university said it has only so far posted online material dating through 1922. It has just completed the first major upload of material available at http://alberteinstein.info.

The rest will be digitized in time, said Hanoch Gutfreund, a university professor who is responsible for Einstein's intellectual property. The project should culminate in all the documents being available to the public with the click of a button.

They will include English translations, since most papers were written in German, and academic notes.
