GENERAL SCIENTIFIC LAWS

1. Universal Gravitation (1666):
* Isaac Newton came to the conclusion that all objects in the universe, from apples to planets, exert gravitational attraction on each other. 
2. Laws of Motion (1687):
* The relationship between an object's mass (m), its acceleration (a) and the applied force (F) is F = ma. 
*For every action there is an equal and opposite reaction. 
3. Electromagnetism 
 (1807 -1873):
* Pioneering experiments uncover the relationship between electricity and magnetism and lead to a set of equations that express the basic laws governing them. 
* One of those experiments unexpectedly yield results in a classroom. In 1820 
* Danish physicist Hans Christian Oersted was delivery his speach to the students about the possibility that electricity and magnetism are related. During the lecture, an experiment demonstrated the 
velocity of his theory in front of the whole class. 
4. Special Relativity (1905):
* Albert Einstein overthrew basic assumptions about time and space by describing how clocks tick slower and distances appear to stretch as objects approach the speed of light. 
5. E = mc2 (1905):
* Albert Einstein's famous formula proves that mass and energy are different manifestations of the same thing, and that a very small amount of mass can be converted into a very large amount of energy. 
* One profound implication of his discovery is that no object with mass can ever go faster the speed of light 
6. Quantum Leap (1900 -1935):
* To describe the behaviour of subatomic particles, a new set ofnatural law was developed by Max Planck, Albert Einstein, Werner Heisenberg and Erwin Schrodinger. 
* A quantum leap is defined as the change of an electron within an atom from one energy state to another. This change happens at once, not gradually. 
7. Nature of Light (1704 - 1905):
* Thought and experimentation by Isaac Newton, Thomas young and Albert Einstein lead to an understanding of what light is, how it behaves and how it is 
transmitted. 
* Newton used a prism to split white light into its constituent colours and another prism to mix the colours into white light, proving at coloured light mixed together 
makes white light. 
* Young established that light is a wave and that wavelength determines colour. 
* Finally, Einstein recognized that light always travels at a constant speed, no matter what is the speed of the measure. 
Superconductors (1911-1986):
* The unexpected discovery that some materials have no resistance to the flow of electricity promises to revolutionize industry and technology. 
* Superconductivity occurs in a wide variety of materials, including simple elements like tin and aluminium, various metallic alloys and certain ceramic compounds. 
8. Quarks (1962):
* Murray Gell-Mann proposed the existence of fundamental particles that combine to form composite objects such as protons and neutrons. 
* A quark has both an electric and a "strong" charge. Protons and neutrons each contain three quarks. 
9. Nuclear Forces (1666-1957):
* Discoveries of the basic forces at work on the subatomic level lead to the realization that all interactions in the universe are the result of four fundamental forces of nature-the strong and weak nuclear forces, the electromagnetic force and gravitation.

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 ...
