    Einstein equations with signed poem on verso

    Albert Einstein Mathematical Formulas Related to his Unified Field Theory with Signed Poem on Verso. Both sides of a single sheet, 6.5" x 7.5" (sight), November 7, 1930. What can be described as a series of mathematical "doodles", including formulas from Riemannian geometry. Einstein muses on a theory in which along with gravity tensor field gΜΝ there is also a vector field AΜ. The fourth row is a well-known formula showing that the covariant derivative of the metric tensor vanishes. Einstein was likely trying to illustrate his unified theory, which never produced any lasting results.

    Einstein has written these formulas on verso of a poem (in German) he wrote as a thank you to his mother's nurse:

    Even if the name is not indicated
    Yet the style is quite well known
    Sister Frieda is the one who wrote it
    Making Einstein be so much happier
    As nobody else has him ever seen
    Always by love thriving
    Dispensing a male scent
    And with gratitude coming from heart

    Committed on 7.XI.30

    By A. Einstein

    She had presented him with a gift of cigars. Matted alongside a photograph of Einstein, and framed to an overall size of 18" x 13.75".
