An Introduction To Programming With Processing left of my screen” to be somewhat uninformed and laughable, not to mention words such as “somewhere” and “my” which might condition a response equivalent to that of an existential dilemma for a computer. If you supply a computer program with specific screen positions in terms of x, y and z and dimensions in terms of width, height and depth either communicated explicitly or implicitly through an expression (which is something we will discuss in more detail later) you will find your programs to have more predictable and efficient results and would help to remove ambiguities that could lead to errors. Screen space and dimensions are concepts we will be dealing with in more detail in later chapters. Of course there are times when randomness and unpredictability are desirable qualities in a program, in which case no other resources available to man can produce a series of unpredictable results more efficiently than computers. This is a testament to why people devotedly invest in computers to provide the sequence of random digits that could potentially make casinos loose millions upon millions to gambling patrons. Computers, and subsequently software are used in various fields of medical technologies where predictability is of the utmost importance. Gambling machines also use software but in contrast to medical software predictability in the application of the software, is an undesirable effect for the machine owners. Abstraction 16
An Introduction To Programming With Processing The Unique Qualities of a Programming Language At the simplest level a programming language should be Turing complete. Turing complete refers to a set of data manipulation rules that, can simulate a Turing machine. This begs the question to be asked, who is Turing and what is his machine? Alan Turing was a British mathematician that is heralded as the father of computer science. He lived from 1912 to 1954 when he died at the age of 41. Turing is responsible for creating the Turing machine which is a theoretical device that operates with a strip of tape imprinted with an infinite array of symbols, the machine is able to read a symbol and alter the symbol and the symbol in turn affects the behaviour of the machine. The tape that the symbols are printed on represent memory and it can move back and fourth so that any symbol can be read by the machine and altered by it, additionally at any given time a symbol is affecting the state of that machine. Turing referred to this machine as an "a(utomatic)-machine" and it forms the fundamental logic of all computer algorithms. This principle is still used in modern computers. A programming language that is Turing complete complies with this logic, and will subsequently be able to run on all computers based on the Turing machine. What this simply means is that programming languages will need to be able to run on a basic computer system that at the very least has a Central Processing Unit (CPU) that is based on the Turing machine, which includes all known operational computer models. Quantum computing models are commonly based on the quantum Turing machine also known as the Universal Quantum Computer, and even these models can be related back to the classical Turing machine. Quantum computing models are theoretical models of how a quantum computer could work once the technology can be implemented, in much the same way that the Turing machine was a theoretical model of today's modern computer before it's current implementation.
