Einstein's Zurich Notebook is a collection of handwritten notes and calculations by Albert Einstein that he made while studying at the Swiss Federal Institute of Technology in Zurich in the late 1890s.
The notebook contains calculations and theories related to electrodynamics, statistical mechanics, and thermodynamics, which were areas of study that Einstein was particularly interested in during this time.
The Zurich Notebook is significant because it provides insight into Einstein's thought process and early development of his theories. It also shows his progression from a student to a renowned scientist.
The original Zurich Notebook is currently located at the Hebrew University of Jerusalem, where Einstein bequeathed his personal papers after his death. However, there are scanned copies available online for public viewing.
The Zurich Notebook does not directly contain the famous equation, but it does contain some early work and ideas that eventually led to the development of the theory of relativity, which E=mc² is a part of. Therefore, the notebook indirectly contributes to the understanding and development of this famous equation.
