EPIC 2014, by Robin Sloan, chronicles what will happen over the next four years, as companies like Google tear down all notions of information and news media, destroying traditional media institutions and giving every user access to information that is as personalized and communal as it is sensational and devoid of ethics.

Mathematics for Programmers 1 :Prime Numbers

A prime number (or prime integer, often simply called a "prime" for short) is a positive integer1" border="0" height="15" width="33"> that has no positive integer divisors other than 1 and itself. (More concisely, a prime number is a positive integer having exactly one positive divisor other than 1.) For example, the only divisors of 13 are 1 and 13, making 13 a prime number, while the number 24 has divisors 1, 2, 3, 4, 6, 8, 12, and 24 (corresponding to the factorization ), making 24 not a prime number. Positive integers other than 1 which are not prime are called composite numbers.

Prime numbers are therefore numbers that cannot be factored or, more precisely, are numbers whose divisors are trivial and given by exactly 1 and .

The number 1 is a special case which is considered neither prime nor composite (Wells 1986, p. 31). Although the number 1 used to be considered a prime (Goldbach 1742; Lehmer 1909; Lehmer 1914; Hardy and …
