R is the world’s most popular programming language for statistical computing. Drug developers use it to evaluate clinical trials and determine which medications are safe and effective; archaeologists use it to sift through mounds of artifacts and track the spread of ancient civilizations; and actuaries use it to assess financial risks and keep economies running smoothly. In The Art of R Programming, veteran author Norman Matloff takes readers on a guided tour of this powerful language, from basic object types and data structures to graphing, parallel processing, and much more. Along the way, readers learn about topics including functional and object-oriented programming, low-level code optimization, and interfacing R with C++ and Python. Whether readers are doing academic research, designing aircraft, or forecasting the weather, R is the tool of choice for statistical application development, and The Art of R Programming is the definitive guide to learning R.

Edward Sapir on Language

Speech is so familiar a feature of daily life that we rarely pause to define it. It seems as natural to man as walking, and only less so than breathing. Yet it needs but a moment’s reflection to convince us that this naturalness of speech is but an illusory feeling. The process of acquiring speech is, in sober fact, an utterly different sort of thing from the process of learning to walk. In the case of the latter function, culture, in other words, the traditional body of social usage, is not seriously brought into play. The child is individually equipped, by the complex set of factors that we term biological heredity, to make all the needed muscular and nervous adjustments that result in walking. Indeed, the very conformation of these muscles and of the appropriate parts of the nervous system may be said to be primarily adapted to the movements made in walking and in similar activities. In a very real sense the normal human being is predestined to walk, not because his elders will assist him to learn the art, but because his organism is prepared from birth, or even from the moment of conception, to take on all those expenditures of nervous energy and all those muscular adaptations that result in walking. To put it concisely, walking is an inherent, biological function of man. : Read the rest :

Who is Jerome Hal Lemelson?

While he was not as well-known as others, Lemelson, known as "Jerry," was one of the most prolific inventors of the 20th century, with some 600 patents to his credit for products like automated warehouses, industrial robots, cordless telephones, fax machines, videocassette recorders, camcorders and the magnetic tape drive used in Sony’s Walkman tape players. Lemelson also made a name for himself-not always in a positive way-as a defender of inventor’s rights, where he actively sued organizations and companies he felt had infringed upon his patents.
