Science World

The difference between a Windows phone and an Android phone is that a Windows phone uses the Windows Operating System and an Android phone uses the Android Operating System. difference between the two operating systems at this time is the number of available apps. Android supports multiple languages, but language support is limited in Windows Phone. The new Phones have been updated. Now windows phone has also windows app store so applications can be accessed from app store. The windows phone is the most selling phone now a days. Windows 7 phone is user friendly and easy to use.

The difference between science engineering and technology was not always clear it confused common people. We can define science, reasoned investigation or study of phenomena, aimed at discovering enduring principles among elements of phenomenal world by employing formal techniques such as the scientific method. Engineering is the process of designing and making tools and systems using results and techniques from science. The development of technology may draw upon many fields of knowledge, including engineering mathematical and historical knowledge to achieve some practical result. Technology is however a consequence of science.


 For example science might study the flow of electrons in electrical conductors by using already existing tool and knowledge while this knowledge may help some engineer to create some tool or machine such computer. The exact relations between science and technology have been debated by scientists historians and policymakers in the late 20th century in part because the debate can inform the funding of applied sciences. In the immediate wake of world war, for example in USA was widely considered. New products new industries require continuous addition to knowledge of laws of nature. This essential knowledge can be obtained only through basic research.

Technology has affected our society in various ways. In many societies, technology helped to develop more advance economies and has allowed the rise of a leisure class. Technological process also produces unwanted products, known as pollution. Various implementations of technology influence the values of a society and new technology raises new questions. Philosophical debates have been arisen to the present and future use of technology in our society. The use of the term technology has changed its meanings significantly over the last 200 years. Before the 20th century the term was not common in English. This term was usually referred to the description or study of the useful arts. The term was often connected to technical education as in Massachusetts institute of technology. Technology rose to prominence in 20th century in connection with the second industrial revolution era. The meanings of technology changed in early 20th century. By 1930s, technology referred not to the study of the industrial arts but to the industrial arts themselves. In 1937 the American sociologist Read Bain wrote that technology includes all tools machines utensils weapons instruments housing clothing communicating and transporting by which we produce them. Bain’s definition remains common among scholars today. But equally prominent is the definition of technology as applied sciences especially among scientists and engineers although most social scientist and engineers who study technology reject this definition. Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage technology refers to the tools and machines that may be used to solve problems in real world.

Technology affects our daily life it is making usage, and knowledge of tools, machines, techniques or methods of organization in order to solve a problem or to perform a specific function. It also refers to the collection of such tools and machinery. Technologies significantly affect human as well as other animal species and environment. The word technology comes from Greek world (technología); which is the combination of τέχνη (téchnē), meaning "art, skill, craft", and -λογία (-logía), meaning "study of-". The term can be applied generally or to specific areas for examples include construction technology, medical technology, and information technology.


The human species has increased use technology began with the conversion of natural resources into simple tools. The prehistorically discovery of the ability to control fire increased the available sources of food and invention of the wheel helped humans in traveling in and controlling their environment. The discovery of ability to control fire increased the available sources of food and wheel invention helped us in traveling in and controlling their environment.





Robotics is the example of advanced technology.
 Recently technological development which includes printing press, telephone and internet has lessened physical barriers. It allows communicating humans freely all over the world. These technologies have not been only used for peaceful purpose only while these also have been used to developed weapons which can be proved very destructive.

First Generation Computer (started from 1940 and lasted on 1956) is also called as Vacuum Tube Computers, because these used used vacuum tubes for circuitry and magnetic drums for memory and were often enormous to take an entire room space. These computers were difficult to operate also, used more space and electricity. As a result these created much heat which was often the cause of malfunctions. The whole machine is 51 feet long, weighs 5 tons, and incorporates 750,000 parts. . It used 3304 electromechanical relays as on-off switches, had 72 accumulators (each with its own arithmetic unit) as well as mechanical register with a capacity of 23 digits plus sign. The arithmetic is fixed-point, with a plugboard setting determining the number of decimal places. There are 60 sets of rotary switches, each of which can be used as a constant register - sort of mechanical read-only memory. First generation computers used machine language which is the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time.

Computer has developed gradually, in different phases. Each generation has brought a major change in computer's world. While this change made computer more accessible, reliable, cheaper and useful. Basically we divide computer development in 5 major sections. We can also call it a historical background of computer. These changes make the computer life complete. These generations are listed below:
First Generation (1940-1956) Vacuum Tubes.
Second Generation (1956-1963) Transistors.
Third Generation (1964-1971) Integrated Circuits.
Fourth Generation (1971-Present) Microprocessors.
Fifth Generation (Present and Beyond) Artificial Intelligence.

Jet engine basically works on the application of Sir Isaac Newton's third law of Physics, which says that every action has a reaction which is equal but in opposite side. air is taken into the inlet of a jet engine (suck) and then compressed (squeeze) by a series of rotors and stators. A fuel mixture is injected into the chamber with the compressed air and ignited. The subsequent combustion is directed, it results exhaust. Due to this Plane is pushed forward. Modern jet engine is made up of several rows of spinning propeller blades called Rotors.
