Hello Candidate,

Vigyan in English is referred as Science, and the modern era or the modern world, is pretty much dependent on this Science and Technology for all its purposes.

Science has been a great boon for mankind, and has helped us reach new heights and scale more expeditions which were not possible earlier. But, it also has some disadvantages- the world it is always in a fear of a great atomic war, most countries are developing nuclear weapons for their own security but which can be hazardous once it gets out of control. Some crooked minds also use scientific developments, as means of frauding and destroying people's lives.

Have a good day.
