The revelatory story of an intellectual giant who made foundational contributions to science and mathematics and persevered in the face of discrimination against women in science. Emmy Noether is one of the most important figures in the history of science and mathematics. Noether's mathematical genius enabled Einstein to bring his General Theory of Relativity, the basis of our current theory of gravity, to fruition. On a larger scale, what came to be known as "Noether's Theorem"-called by a Nobel laureate "the single most profound result in all of physics"-supplied the basis for the most accurate theory in the history of physics, the Standard Model, which forms our modern theory of matter. Noether's Theorem is also the tool physicists use to guide them towards the holy grail of a unified theory and is the secret weapon wielded by researchers at the cutting edge of fields as diverse as robotics, quantum computing, economics, and biology. Noether's life story is equally important and revelatory in understanding the pernicious nature of sexual prejudice in the sciences, revealing the shocking discrimination against one of the true intellectual giants of the twentieth century, a woman effectively excluded from the institutions, perquisites, and fame given male counterparts in the world of science. Noether's personality and optimistic, generous spirit, as Lee Phillips reveals, enabled her unique genius to persevere and arrive at insights that still astonish those who encounter them a century later.
