science is a catagory of subjects.
it is combined of four subjects.the four subjects are are mathematics  , chemistry , biology and physics.
these subjects are very important to be studied.
the things or the lessons we study in these subjects is applied by us in our daily life.

we use maths in the shops to calculate price of items .
if we are nor aware of this subject then any one can cheat us .
we can avoid this by calculating the price on our own and this is pssible only if we know how to do addition , multiplicatication  , division , subtraction etc.

next comes the subject biology.
this subject is relation to the study of animals and plants , their structure , their habitat and their physical features.
we study the functions of different organs in animal and plant bodies.
this gives us a huge knowledge about our own bodies as well as other plant and animal bodies.
we can avoid in take of  food which we cannot digest.

the next is chemistry.
chemistry usually refers to chemicals .
we use chemicals almost everyday.
chemicals makes many things possible like the formation of cosmetics  ,fire extinguishers , fertilizers etc.
we can avoid diseases by the advanced medicines.

then comes the last subject , i.e , physics .
this subject contains , heat , measurement , light , electricity  , sound etc.
physics is more or less related to maths.
the calculations of physics can only be done if we know mathematics.
with the help of physics we can know how things and phenomenons are happening around us.

this in turn will lead to more development.the scientists are still in try to improve gadgets , form new medicines and improve the living conditions of the people on earth.the science is becoming more and more advanced.it can be advanced further.some new diseases are occuring.the scientists are researching for the formation of new and powerful medicines that can cure these unknown disease.

This is how I will develop my nation India. Using science I will find solutions to problems that India is facing. 

Science is the basis along with mathematics for the progress in food technology, agriculture, comfort, transport, space, oil, medical fields.  Science and mathematics form the foundation for all the engineering fields.

Science has progresses a lot during the last few centuries and the fastest and unimaginable progress has been made in the last 50 years.  The research efforts are continuing on further for the better future of people and hence for the country.

I can make use of the developments in space science and findings known so far in the various expeditions to other planets.  I can make use of the developments in the space science, for obtaining business for ISRO.  We get more contracts from other countries to send their satellites.

We can build very good defence and attack related weapons and surveillance products using the most advanced scientific knowledge and engineering techniques and practices.  We can sell these devices and equipments to other countries. There is a demand for these.  We can also reduce the huge expenditure we are incurring on defence requirements.

We can produce better quality crops, already scientists and agricultural experts advise farmers on better cultivation methods suitable for different soils.  Thus we can improve food availability in the country.

Dirt, water pollution, adulteration, unhygienic living conditions of poor people is one of the causes for a lot of expenditure by the people and the country.  As the scientific awareness increases among people, the situation will become better.  Also, science can find better solution for these problems.

I will make more scientists in the fields of medicine, physics, chemistry, and other sciences.  They will improve the scientific standards and  enhance the name of the country in the world. As science creates new fields and new jobs, it will help unemployed.

We need good scientific applications to improve the protection of our environment and to reduce the pollution by vehicles and other burning of many fuels.  The health of the community will improve and thus the country will benefit.  I will also invent new fuels which reduce pollution and have higher calorific value.

The earning capacity of people of India increases when they become experts in science and engineering.  We can do the jobs at international and national level more effectively and compete better internationally.

I will try to improve energy utilization efficiency and conservation of energy at homes, offices and industries. So we will save energy.  I will make more use of solar power.  I will set up many more atomic power plants, after taking into account safety aspects.  These are essential and will reduce the power supply problems.  Many industries which have been shut down due to power-shortage will then run again and generate employment.  I will look for generating power from the renewable energy sources like solar and geothermal energy too.

So much advancement has taken place in the latest technologies like nano-technology and semiconductor technologies.  There are many engineers and scientists in these areas.  I will set up many industries to manufacture electronic goods and equipment.  This will save a lot of foreign exchange and generate internal employment.  India's economic condition will improve by this.  I will use latest science to find ways of making and exporting of goods.

I will make people of India more logical and scientific instead of beingsuperstitious.  Then poor people of India will develop faster.

I will use more advanced science and engineering techniques to explore more minerals, natural gases and oil in our land and in our ocean waters.  We will save on the purchases of these from other countries.

I will introduce nutrition, hygiene and health science as a subject in every science, arts, law, or engineering degree.
