Treatise on Light was published in 1690 and is probably the largest scientific volume on light published before Newton's Opticks. The book explains how light travels (i.e., that it has a certain velocity), and what happens when it hits a surface (refraction and reflection). A large portion of the book is devoted to the double refraction occurring in Iceland chrystal, and all drawn conclusions are proved geometrically. Christiaan Huygens (1629 - 1695) was a prominent physicist and astronomer. His main discoveries are the centrifugal force, collision laws for bodies and the argument that light consists of waves...

This is an account of Nellie Bly's travels through Mexico in 1885. The book was originally a series of individual articles that she submitted to the Pittsburgh Dispatch newspaper for publication. In them she described the conditions of the people and the political system she found in Mexico. Her narratives focused mostly on the impoverished and disadvantaged in a country whose government was extremely corrupt. Bly was perhaps what we now term a feminist, striving for the empowerment and independence of women...

The Republic is a Socratic dialogue written by Plato around 380 BC concerning the definition of justice and the order and character of the just city-state and the just man. It is Plato's best-known work and has proven to be one of the most intellectually and historically influential works of philosophy and political theory. In it, Socrates along with various Athenians and foreigners discuss the meaning of justice and examine whether or not the just man is happier than the unjust man by considering a series of different cities coming into existence "in speech", culminating in a city (Kallipolis) ruled by philosopher-kings; and by examining the nature of existing regimes...

This dialogue brings Socrates face to face with the famous sophist Gorgias and his followers. It is a work likely completed around the time of "Republic" and illuminates many of the spiritual ideas of Plato. The spirituality, as Jowett points out in his wonderful introduction, has many ideas akin to Christianity, but is more generous as it reserves damnation only for the tyrants of the world. Some of the truths of Socrates, as presented by Plato, shine forth in this wonderful work on sophistry and other forms of persuasion or cookery.

Eminent British botanist Agnes Arber provides an authoritative history of printed Herbals -- books widely used in early modern Europe to catalogue the uses of different kinds of plants.
