The Grammar of Science, originally published in 1892, was considered an essential read by budding young scientists like Albert Einstein. Pearson's work contributed to Einstein's greatest discoveries by introducing him to the ideas of relativity of motion, equivalence between matter and energy, and the concept of antimatter. Pearson opens his book with a definition and discussion of science itself, detailing what is required for inquiries to be scientific in nature. He then moves on to discuss space and time, motion, matter, and the future of scientific progress. Professionals and students alike will be fascinated by Pearson's insight into the nature of reality. British professor KARL PEARSON (1857-1936) worked at University College in London. He invented mathematical statistics and formed the Department of Applied Statistics at the University of London. He wrote many books and papers, including a biography of Francis Galton, a proponent of eugenics, and studies on evolution.
