# Albert Einstein’s 23 Mistakes

Date: December / 29 / 2009 + Comments: 0

Albert Einstein was a genius but also he made some mistakes, specially with the details of his equations and theories. In the book Einstein’s Mistakes: The Human Failings of Genius (W.W. Norton, $12.93), Hans Ohanian writes that Albert often let his intuition overrule flawed proofs and shaky math.

DISCOVER Magazine also posted a story on Einstein’s biggest flubs: thinking **black holes were impossible**, believing the **universe was static**, and saying that “God does not play dice.”

## Chronology of Albert Einstein’s Mistakes

- 1905 Mistake in
**clock synchronization**procedure on which Einstein based special**relativity**. - 1905 Failure to consider Michelson-Morley experiment.
- 1905 Mistake in transverse mass of
**high-speed particles**. - 1905 Multiple mistakes in the mathematics and physics used in calculation of
**viscosity of liquids**, from which Einstein deduced size of molecules. - 1905 Mistakes in the relationship between thermal radiation and quanta of light.
- 1905 Mistake in the first proof of
**E = mc2**. - 1906 Mistakes in the second, third, and fourth proofs of
**E = mc2**. - 1907 Mistake in the synchronization procedure for accelerated clocks.
- 1907 Mistakes in the Principle of Equivalence of gravitation and acceleration.
- 1911 Mistake in the first calculation of
**the bending of light**. - 1913 Mistake in the first attempt at a theory of general relativity.
- 1914 Mistake in the fifth proof of
**E = mc2**. - 1915 Mistake in the Einstein-de Haas experiment.
- 1915 Mistakes in several attempts at
**theories of general relativity**. - 1916 Mistake in the interpretation of Mach’s principle.
- 1917 Mistake in the introduction of the cosmological constant (the “biggest blunder”).

- 1925 Mistakes and more mistakes in the attempts to formulate a unified theory.
- 1927 Mistakes in discussions with Bohr on
**quantum uncertainties**. - 1933 Mistakes in interpretation of quantum mechanics
