This is a book that quietly grows on you.
Mary Somerville's life could be a case history for encouraging the education of Women. She achieved in spite of the restrictions and attitudes of her time. That she was outstandingly clever there is no doubt, but her account of the events that were keys or turning points in her search for knowledge is fascinating as well as illuminating. The three sets of papers that this book is extracted from were written in old age yet it is a lively and alert mind that springs forth. Her great gift to Science was to make it intelligible to the general reader and her papers reflect this, she speaks of meeting great scientists as friends and mentors. She records events succinctly but completely so as not to leave questions hanging in the air.
To me this is a wonderful insight on a great life, but, as a previous reviewer points out, the narrator changes to the daughter for periods without warning which causes confusion at times. This is not a technical book in any way, but if you haven't heard of Laplace, the Herschels or Newton and you have no idea of 19th Century European history, or indeed our own, over her lifetime, you will lose much of the enjoyment.
