MATHEMATICS
          Mathematics is the science that deals with shapes, quantities and arrangements. Archmedes is known as the father of Mathematics (287BC-212BC). Mathematics seek and use patterns to formulates new conjuctures.They resove truth or false by using mathematical proof. Mathematics developed by counting, calculation, Measurements, Shapes and motion of physical objects. 
Definition
Mathematics has no general accepted definition. Until 18th century Aristotle defined mathematics as "the science of quantity". Many mathematicans take no interest in definition they simply say "Mathematics is what Mathematican do".
Three leading definition of mathematics today are logicist, intutionist, and formalist.
Logicist - In terms of Benjamin peirce, the definition of mathematics in terms of logic are "the science that draws necessary conclusion" and also said that " All mathematics is symbolic logic" by Mathematician Rusell.
Intutionist - L.E.J.Brouwer, defines "Mathematics is the mental activity which consists in carrying out construct one after the other".
Formalist - Haskell Curry, defines Mathematics as "the science of formal systems".
Mathematics include in many fields such as Natural science, Engineering, Medicine, Finance and Social Sciences.The Mathematics can be classified as 
1.Pure Mathematics
* Number Theory
* Algebra
* Geometry
* Arithmetic
* Combinatorincs
* Topology
* Mathematical Analysis
2.Applied Mathematics
* Calculus
* Statistics and probability
* Set theory
* Trigonometry
Rules in Mathematics
The main rules in Mathematics is BODMAS. 
*Brackets (parts of the calculation always comes first)
*Orders (numbers involving powers or squares)
*Division
*Multiplication
*Addition
*Subtraction
Skills developed by studying Mathematics
*Critical thinking

Introduction to C Programs

INTRODUCTION The programming language ‘C’ was developed by Dennis Ritchie in the early 1970s at Bell Laboratories. Although C was first developed for writing system software, today it has become such a famous language that a various of software programs are written using this language. The main advantage of using C for programming is that it can be easily used on different types of computers. Many other programming languages such as C++ and Java are also based on C which means that you will be able to learn them easily in the future. Today, C is mostly used with the UNIX operating system. Structure of a C program A C program contains one or more functions, where a function is defined as a group of statements that perform a well-defined task.The program defines the structure of a C program. The statements in a function are written in a logical series to perform a particular task. The most important function is the main() function and is a part of every C program. Rather, the execution o...

Performance

Performance ( Optional ) * The I/O system is a main factor in overall system performance, and can place heavy loads on other main components of the system ( interrupt handling, process switching, bus contention, memory access and CPU load for device drivers just to name a few. ) * Interrupt handling can be relatively costly ( slow ), which causes programmed I/O to be faster than interrupt driven I/O when the time spent busy waiting is not excessive. * Network traffic can also loads a heavy load on the system. Consider for example the sequence of events that occur when a single character is typed in a telnet session, as shown in figure( And the fact that a similar group of events must happen in reverse to echo back the character that was typed. ) Sun uses in-kernel threads for the telnet daemon, improving the supportable number of simultaneous telnet sessions from the hundreds to the thousands.   fig: Intercomputer communications. * Rather systems use front-end processor...

HEAT AND THERMODYNAMICS

Heat: * Temperature is the thermal state of the body, that chooses the direction of flow of heat.  * “Heat is a form of energy transfer between two systems or a system and its surroundings due to temperature difference between them.  Specific heat capacity  * Specific heat capacity of a substance is determined as the quantity of heat required to raise the temperature of 1 kg of the substance through 1K. Its unit is J kg^–1K^–1. * The specific heat capacity of water is the highest for any substance, 4180 J/kg K. It is 30 times the specific heat capacity  of mercury which is about 140J/kg K.  Specific Latent Heat  Specific Latent Heat of fusion of any substance is the quantity of heat energy needed to melt one kilogram of a substance without change in temperature. The symbol used is L. The unit for specific  latent heat is Joule/kilogram or J/kg  The Gas Laws  * Boyle’s Law  “Temperature remaining constant, the pressure of a given mass of ...
