What is Science?
   Science is a special knowledge that helps us to understand          nature and gives us the ability to solve an existing problem.
                                                                                              We use     this knowledge for the betterment of our world.

   
    

  Why should we study science?
  We should not study science just to            understand the theorems or just to pass    our exams. We always have find a way      to use the knowledge in our practical life. Science is the key to    make this world a better place. 


  Division of science: 
 Basically science is divided into two parts-
 1. Theoretical Science: This is the part of the science where   most of the work is theory based. Some theories have not     proved practically yet.
                          Scientists use various mathematical calculations to prove the theories.
                        Examples of some theoretical science are Quantum theory, String theory etc.

2. Practical Science:This is the part of the science which we use in our practical life.
                                                  For example we can say making any kind of machine is the part of practical science.


Area of Science:
Science deals with the smallest particle like atoms and molecules as well as it deals with the massive stars and planets.
We sent rockets to the space for space exploration. It takes very advanced knowledge of engineering to build a rocket. Engineers are always working to make human life  easier.
                                                                                    Medical science is also developing so fast. Now we have advanced medicines to cure diseases like malaria , plague,polio etc.
                                                                                   Internet is one of the most important source of information in today's world. It is also the blessing of science.
                        Now engineers are working on artificial intelligence. The robots who will be able to take their own decision.




  How should we use Science?
  Science can be used for the betterment of mankind or it can        bring the end of the world. It is up to us how we use it .
                                                                               Same thing can be used to solve a problem in the world as well as to destroy the world.
  For example nuclear power can be used to produce a massive amount of energy that can help us to overcome the energy supply problem in the world or it can be used to make nuclear weapon . It is totally our duty to use science in a healthy way and avoid it's harmful effects.
