that ideas of gender are brought to the table already when practicing science and can inform what evidence people look for or areas they choose to study, and that whatever is found then influences theories of gender. The various contradictions shown through the achievements and silencing of women in science throughout history shows how nature and the society can influence gender and science. Schiebinger not only addresses the gender in the context of science, she also describes the feminism is changed through the history and culture. It is important to note that the book is written from a Western perspective and that the culture she discusses is that of the Western World, and in many cases, more specifically, the United States. The first of the book's three sections takes a look at the impacts of some of the first women to be known to have participated in science, such as Christine de Pizan and Marie Curie. The section also examines the numerical count of women in the various fields of science in academics in the late 20th century United States, as well as looking at the breakdown of other factors, such as pay rates and the level of degree held, in relation to gender. The section goes on to theorize that the cultural reinforcement of gender roles may play a factor as to why there are fewer women in science. The second section, 'Gender in the Cultures of Science', argues that science has been gendered as being a masculine field and that women report a distaste for the excessive competition fostered by academic science. The section also argues that the splitting of gender roles in personal life, where women still take on a majority of domestic responsibilities, may be a reason that is hindering women in scientific fields from accomplishing more. The third section of the book, 'Gender in the substance of Science' details the perspectives that women have brought to fields such as medicine, primatology, archeology, biology, and physics. In fact, Schiebinger states that as of the writing of the book, that women earned nearly 80 percent of all Ph.D.s in primatology, and yet, despite this, having a large number of women scientists in a field does not necessarily lead to a change in the assumptions of science, or the culture of science.
