Oblique aerial view of the eruption of May 18, 1980, which sent volcanic ash, steam, water, and debris to a height of 60,000 feet. The mountain lost 1300 feet of altitude and about 2/3-cubic mile of material. Note the material streaming downward from the center of the plume and the formation and movement of pyroclastic flows down the left flank of the volcano. Photo by Austin Post.

An Essay on the Principles of Population
$9.22
Book
The Rev. Thomas Robert Malthus (February, 1766 – December 23, 1834), who is usually known as Thomas Malthus, although he preferred to be known as "Robert Malthus," was an English demographer and political economist best known for his pessimistic but highly influential views. Although it is popularly assumed that it was these pessimistic views that gave economics the nickname Dismal Science, the phrase was actually coined by the historian Thomas Carlyle in reference to an anti-slavery essay written by John Stuart Mill. Malthus was born to a prosperous family. His father was a personal friend of the philosopher and sceptic David Hume and an acquaintance of Jean-Jacques Rousseau. The young Malthus was educated at home until his admission to Jesus College, Cambridge in 1784. There he studied many subjects and took prizes in English declamation, Latin and Greek. His principal subject was mathematics. He earned a masters degree in 1791 and was elected a fellow of Jesus College two years later. In 1797, he was ordained and became an Anglican country parson. Malthus's views were largely developed in reaction to the optimistic views of his father and his associates, notably Rousseau and William Godwin. In An Essay on the Principle of Population, published in 1798, Malthus predicted population would outrun food supply, leading to a decrease
in food per person. This prediction was based on the idea that population if unchecked increases at a geometric rate (i.e. 2, 4, 8, 16, 32, 64, 128, etc.) whereas the food supply grows at an arithmetic rate (i.e. 1, 2, 3, 4, 5, 6, 7, etc.) (See Malthusian catastrophe for more information.) Only misery, moral restraint and vice (which for Malthus included contraception) could check excessive population growth. Malthus favoured "moral restraint" (including late marriage and sexual abstinence) as a check on population growth. However, it is worth noting that Malthus proposed this only for the working and poor classes. Thus, the lower social classes took a great deal of responsibility for societal ills, according to his theory. Essentially what this resulted in was the promotion of legislation which degenerated the conditions of the poor in England. The influence of Malthus's theory of population was very great. Previously, high fertility had been considered an economic plus since it increased the number of workers available to the economy. Malthus, however, looked at fertility from a new perspective and convinced most economists that even though high fertility might increase the gross output it tended to reduce output per capita.
Experiments in Plant Hybridization (1865)
$6.43
Book
Mendel was born in German-speaking family in Heinzendorf, Moravia, Austrian
Empire (now Hynice, district of Nový Jiín, Czech Republic). During his childhood Mendel worked as a gardener, and as a young man attended the Philosophical Institute in Olomouc. In 1843 he entered an Augustinian monastery in Brno. He was later sent to the University of Vienna to study.
Gregor Mendel was inspired by both his professors at University and his
colleagues at the monastery to study variation in plants. He commenced his study in his monastery's experimental garden. Between 1856 and 1863 Mendel cultivated and tested some 28,000 pea plants. His experiments brought forth two generalizations which later became known as Mendel's Laws of Inheritance.
