Computer Science
The branch of science which deals the study of computer design,information and scope in computer system is called computer science.Computer science gives the many information of networking and telecommunication about computer.The programmable machine that stores and retrieves the data from the user is called computer.Computer is also electronic device which works diffucult works faster than the man in short time.Computer is wonderful achievement of science and technology.The main parts of computer are desktop,mouce,CPU,keyboard and so on.Computer consists of many arithmatic and logical operations. In compute design there are mainly three types of units.These units are central processor unit,memory units and type-writer input output units.The hardware design of computer is divided into three parts.They are system design,logic design and circuit design.The software system of computer affects the hardware design of computer.Computer analyse the data or informations and produces further information that the manager wants to know.Hence the computer is most powerful and useful devices for human beings. With the advancement of science and technology,the importance of computer is increasing day by day.In the big bussiness firms and institutions it is not possible to handle all the works by the man.The computer does the work with very easily in short time.Computer helps to save our money and time.Computer does the work efficiently and accurately.Nowadays there are found to be many facilities of computers.Computer is used in various fields like education,banking,networking,accounting and so on.With the help of computer we play many games for passing time.Computer gives us entertainment also.In developed country like Japan and America computer is used for passenger reservation on railways.There are some drawbacks of computer.Computer makes us lazy and dull.Computer creates the problem of unemployment Because computer can do many works instead of people.In context of Nepal if there is well management of computer science then Nepal country may be developed in future.
Atmospheric Scence
The science which gives the structure,composition of gases,information and importance of atmospher is called atmospheric science.The earth is surrounded by the mixture of gases by means of air is called atmosphere.In real the air is invisible and we can just feel it.In atmosphere there are some principle gases.They are Oxygen and Nitrogen.Also there are few other gases like Water vapour,Carbondioxide,Neon,Helium,Hydrogen,ozone and so on.In atmosphere the amount of Nitrogen is 78% and the amount of Oxygen is 21%.Remaining 1% consists of other gases.We accept Oxygen from air and give out Carbondioxide.Green plants accept Carbondioxide and give up oxygen in the process of photosynthesis.In atmosphere there are found various particles.Nowadays the atmosphere is polluted by the man's activities.The smoke coAming out of the factory,industries and vehicles make the atmosphere polluted.Now the people cut down the trees for various purposes.Because of this the amount of useful Oxygen gas is decreasing and the amount of carbondioxide gas is increasing which is not important for human beings.It damages the balances of different gases in the atmosphere.If it does continuously then we must face difficult situation in the future.Hence the people of this world must think seriously about the balances of the atmosphere. Structure of Atmosphere:According to the different in temperature the atmosphere is divided into four layers.These layers are Troposphere Stratosphere Mesosphere Thermosphere. Troposphere:First of all we live in the troposphere layer.one layer of the atmosphere which closest to the earth is called troposphere.The temperature of this layer decreases as height is increasing.Nearly 75% of the atmosphere of earth lie in the troposphere layer.All the weather condition of the earth like most clouds,rain and snow take place in this layer. Stratosphere:The sphere which is extended from tropopause abou 50 kilometres above the surface of the earth called stratosphere.The ozone layer lie in the stratosphere.Ozone takes the ultraviolet radiatio from sun.In some amount the moisture presents into this layer so most of clouds are rare. Mesosphere:About 80 kilometres above the earth the layer is extended from the stratosphere called mesosphere.According to the altitude the temperature of this layer decreases.Specially strong wind blow happens in this layer during the winter. Thermosphere:The upper layer of the atmosphere of the earth called thermosphere.At the mesosphere it starts and continues into the outer surface.The thermosphere is divided into two layers.one is lower layer where the oxygen molecules are found in the form of atom.The another is outer layer where the Hydrogen and Helium are found.
Environmental Science
The science which deals the study of structure,effects,importance and informations of environmental pollution and its solutions is called environmental science and technology.The environmental science shows the interrelationship between nature environment.The broad terms which consists of all living beings called environment.The environment also consists of non living beings like topography,climate,soil,minerals and so on.Man produces various things by his talent,knowledge and wisdom.The environment is classified into natural and man made activities.As a result the environment is polluted by different activities of man is called environmental pollution.The smoke coming out of the facteries,ndustries and vehicles make the air polluted.Trees are our friend.They take carbondioxide a pasion,the air gives us life living oxygen gas.But the people cut down the trees for various purposes.In the absence of trees there creates the problem of soil erosion and causes the rainfall.Thus the air is polluted.The land is also polluted.Then there takes place the problem of sound pollution.The environmental pollution has negative effects on the help of the people and economic aspects.It brings unfavourable weather.Environmental pollution causes draught,landslide,soil erosion and flood causes decline in agricultural productions.The people may suffer from different dangerous diseases. So it is clear that environment should be saved for the common benifit of human beings.The government and people all over the world think seriously to adopt measure to environmental pollution.For removing the environmental pollution there must be well management of environmental education in schools and colleges.To control the environmental pollution we never cut down the trees.For this we should give the importance of environmental science to other peoples.Also we must follow the scientific methods to save the environment.
Health Science
The branch of science which explains the benifit,effects and research of health problems of the people is called health science.We have already known about "Health is Wealth".Healthy man is happy and he can earn wealth.An unhealthy man can not be happy.A healthy man is also bold confident.He does his work with very easily and get success in his life.Healthy man can work better and harder and he does not lost his hearth.But unhealthy man is timid so he can not do any difficult work.He can not get success in his life .Also he has no strength of mind.Many things are necessary for keeping good health.First we need pure air.Then we also need clean drinking water.We need good food.We must do physical exercise for better health and rest for good health.Dirty water is the main source of many diseases.The another important thing for better health is balanced diet.We must use plenty of milk,eggs,green vegetables,fish and fruits in our daily life for good health.Physical exercise plays vital role for health.The health science tells us important fact that is "prevention is better than cure. For the development of the country depends on the health of the people.so there is the great scope of health of people.Health science provides the health education.With the help of health education people should be taught how to be healthy.Health educaion should be introduced in the shools.Then the cildren know the importance of health and they can be happy.Health education encourages the hospitals and health posts for the treatment of health problems.The hospitals has great scope at the time of emergency,accidents etc.At the time of accidents and emergency the hospital saves the life of the people.In hospitals there must be well management of doctors,nurses,health assistances,compounders and stocks of medicine for treatment.By the health science most of the health orgnisation give the introductions of many diseases and idea for how to control these diseases.Also health science participates the community health educations.The community health education gives the discovery of diseases.
Scope of Science and Technology
First science and technology is great achievements for human beings.Science and tehnology makes everything possible.The primitive people passed very difficult life.They had no any knowledge concerning of science.They didn'n know how to pass comfortable life.By technical science ,man has done tremendous progress in the field of agriculture,transport and communication,health and so on. As a whole science and technology is the symbol of human civilization.Science tells us that it is the technique of success.There are development made by science in different fields such as Food:Food is the necessary thing for us.Now we follow the scientific methods for how to grow big food crops.Nowadays the scientists are trying to grow crops in water without soil. Clothing:Science developed modern clothes.So the people wear variety of clothes. Shelter:Gradually people learnt to make houses of attractive design from science. Health:Science gave many idea about health.Science introduced dangerous diseases like AIDS,Tuberculosis and so on.Science developed the medicines for the treatment of the people. Transport:Science has developed modern means of transport.So people can travel quickly and safely by modern means of transport like buses,cars,aeroplanes,ships etc.With the help of jet planes we can round the whole world in twenty four hours. Communication:Communication makes the human life very simple by telegraphs,telephone,wires and so on.Commnication has great importance for the life of the people. Power:For the different kinds of hard work power is necessary.Because of the power of machine,human life is cmfortable.
Physical Science
Physical science is branch of science which deals with the study of natural living and non living things or matters and expands the imoprtance of this science.On the other hand physics is the on form of the mathmatics because mathmatics modified the physical science.Everything in this universe is the creation of physical science.Without physical science the discovery of other sciences is not possible.So physical sciences has great importance compared to other science.Physical science gives many information in the developmental works like engineering,doctors,agriculture and so on.Physics deals with the study matter and energy.
Really in the stone age the man passed very diffiucult and miserable life.They didn't suffer the facility of science and technology.They didn't know how to pass comfortable life.While physical science developed,then the man suffered from the various facility science.Then the physical science makes the life of the people simple and comfortable.With the help of physical science the scientists invented modern instruments and machines which make human life confident.The achievements of physical science are to many to count.Physical science has changed the entire world.It is not the same in which our ancestors lived.If there were to retern now to earth,they would no recognise it.In the othere sense physical science made our life trouble free.Very fast means of communication and transport have made the world smallers.
Some familiar examples of achievements of physical science are telephone,radio,television,aeroplanes,jets,ships,computer,laptop and so on.Electricity is another gift of physical science.The advantage of electricity are unlimited.It lights our houses,shops and streets.It can be use in our factories for doing hard work.Physical science has given us wonderful medicines.It has conquered epidemics.Now even the brain can be operated upon and many vital organs can be transplanted and we can live a longer and healthier life.Physical science has proved great blessing and it has given us many wonderful inventions.Physical science formulates other sciences like chemical,biotechnology,astronomical,earth sciences.
There are some basic fundamentals of physical science.In physical science we take the knowledge about force,motion,electricity and magnetism,etc.Physical science helps us for research in different fields.Physical science gives the knowledge of nuclear phenomenon.So if the government are allowed the physical science compulsary then the country may be developed in future.
