		In its most general sense, computer science (CS or compsci) is the study of computation and information processing, both in hardware and in software.
		In practice, computer science includes a variety of topics relating to computers, which range from the abstract analysis of algorithms, formal grammars, etc. to more concrete subjects like programming languages, software, and computer hardware.
		Science kits, science lessons, science toys, maths toys, hobby kits, science games and books - these are some of many products that can help give your kid an edge in their science fair projects, and develop a tremendous interest in the study of science.

	Invariant (computer science) - Wikipedia, the free encyclopedia
		In computer science, optimising compilers and the methodology of design by contract pay close attention to invariant quantities in computer programs, where the set of transformations involved is the execution of the steps of the computer program.
		A loop invariant is a constraint on the input to a loop that should be satisfied by every iteration of the loop.
		A class invariant is a constraint on the state of an object that should be satisfied by every method of the class.

		As the term embodying the advocacy of a specific approach to computer programming, one that urges that it be treated as an engineering discipline rather than an art or a craft, and advocates the codification of recommended practices in the form of software engineering methodologies.
		Many believe that software engineering is a part of computer science, because of their close historical connections and their relationship to mathematics.
		The Annual International Computer Software and Applications Conference was first held in Chicago in 1977 and is designated as the IEEE Computer Society signature conference on software technology and applications.

		Although developments in computing theory are intangible, theory underlies many aspects of the construction, explanation, and understanding of computers, as this chapter demonstrates.
		Computer science had achieved the title "computer science" without much science in it, [so we] decided that to be a science you had to have theory, and not just theory itself as a separate program, but everything had to have a theoretical basis.
		Although funding for theoretical computer science has declined as a percentage of the NSF budget for computing research (it constituted 7 percent of the budget in 1996, down from 20 percent in 1973), it has grown slightly in real dollars.

		This computer science concentration program is intended to prepare students for either graduate work or employment in computer science by offering both the degree of Bachelor of Arts and the degree of Bachelor of Science.
		Students taking a bachelor's degree in computer science should note that by judicious employment of courses from another field for extra-departmental requirements or for electives, a minor field can be developed that is often in itself a solid basis for graduate or professional work in that field.
		Computer science students may use AP credit for chemistry or physics to fulfill their physical sciences requirement in general education or the physical sciences component of the concentration.

	Executive Summary
		Science standards, curriculum, assessment, and instruction—as well as professional development for teachers—should be conceived of, designed, and implemented as a coordinated system.
		In order to provide meaningful opportunities for science learning, policy makers, education leaders, and school administrators need to ensure that adequate time and resources are provided for science instruction at all grade levels for all students.
		Recommendation 7: University-based science courses for teacher candidates and teachers’ ongoing opportunities to learn science in service should mirror the opportunities they will need to provide for their students, that is, incorporating practices in the four strands that constitute science proficiency and giving sustained attention to the core ideas in the discipline.

	Teaching Programming to Liberal Arts Students:Using Loop Invariants (Site not responding. Last check: 2007-10-14)
		To make this unit possible, and because ultimately it gives students a deeper understanding of the nature of computer science as both an empirical and a mathematical discipline, we redesigned the programming part of the course so that loop invariants are introduced and used as soon as the while statement is presented.
		The debate concerning the importance of loop invariants has not concluded but one part of the debate should be over: teaching the use of loop invariants to correctly construct loops is pedagogically feasible at all levels of computer science instruction.
		Central to all these presentations and papers is the point that it is not the topic of loop invariants that must be omitted when one moves from an advanced computer science course to a beginning one; rather, the way in which it is presented must be modified.

	Scientists on science: tentativeness
		In this sense, tentativeness in science is a form of decisiveness, as it allows research to move forward despite constant uncertainty.
		In a similar manner, many of the formal concepts in computer science are based on mathematical proofs, and as such remain very stable.
		Its broad acceptance by scientists suggests that the use of this as part of the legal definition of science is wholly appropriate.

	Class (computer science) - Enpsychlopedia (Site not responding. Last check: 2007-10-14)
		An invariant is a constraint on the state of an object that should be satisfied by every object of the class.
		An invariant is what distinguishes datatypes and classes from each other, that is, a class does not allow use of all possible values for the state of the object, only those that are well-defined by the semantics of the intended use of the datatype.
		In computing, when specifying an abstract class, the programmer is referring to a class which has elements that are meant to be implemented by inheritance.

		The approach uses program invariants: when a particular pattern of invariant relationships appears at a program point, a specific refactoring is applicable.
		Our experiments suggest that dynamic analyses may be remarkably accurate: the dynamically detected invariants had an average precision (a measure of correctness) of.95 and an average recall (a measure of completeness) of.94.

	Crank Dot Net \| science
		However, with evolution of science and the advent of uncertainty theory and quantum science, it became clear that matter could not be understood in isolation of mind and consciousness.
		Science evolved from the study of interaction of matter to the interaction of fields and concluded that quantum fields is the physical reality and this physical reality, arises from a unified field.
		Unbridled gullibility can destroy science, but unbridled skepticism is no less a threat because it brings both the excessive preservation of the status quo and the supression of unconventional ideas.

		Invariants are especially useful in introductory courses (CS1 and CS2) but are usually avoided because of the mathematical notation associated with them and because most textbooks have brief, if any, coverage of them.
		Self-reference is one of the cornerstones of computer science from the unsolvability of the halting problem, to writing a Pascal compiler in Pascal, to reveling in the beauty of Quicksort.
		Recent literature has focused on introducing the patterns to computer science educators, but not on the situations and contexts in which the patterns are appropriate.
