Over the years man has made a number of discoveries and inventions , one cannot say which one is the best of all. Different people will have different views on it.Well according to me , mobile phones are the best invention made by man.Over the click of a button, calls can be made to people thousands of kilometres away.Long ago people had to send letters, and wait for days to have the reply.The invention of mobile phones has made life easier in the fields of communication.Now-a-days, mobile phones are not just used for voice communication but we can also have a face-to-face chat.Features like the internet facility and GPS which are now accompanied with phones have made internet portable and the cost at which they are available has made it affordable for the common man.So according to me , mobile phones are one of the best inventions made by mankind .

Invention is the activity of investigating and finding a new method
of achieving something, or a new device for use by
people, or a new principle or concept or law that governs some
physical quantities. An invention is a qualitative jump over the existing implementation. Inventions are the ones that made man progress
from cave man to a a space voyager.
1. Language:
Among the ancient inventions, the invention of a Language and its script as a medium of communication is the most important invention. With out a means to express ones views either verbally or by means of writing, human beings would have been as good as the cave man.
The language made a person do some thing in a life time and pass it on to the next generation. The knowledge and culture gained by one generation became the starting point for another generation. Hence we progressed. We had books because we had a language to write. Without reading books, even the great scientists could probably not invent much.
2. Wheel
The rotating wheel is one of the most important inventions of the ancient man. A wheel is the basic part needed to transport a person or a good across from one location to another. Without a wheel, pyramids, Eiffel tower, Taj mahal, and perhaps even our own house could probably be not built. People had to walk and carry every load by themselves or on animals. Many people would be doing labour work still, with out a wheel.
3. Semiconductor based transistor
The invention of a semiconductor transistor device by Bardeen, Brittain and William Schockley has lead us to the development of most sophisticated computers, laptops, cell phones, calculators, appliances, weapons, gadgets etc. In fact, this twentieth century advanced invention is the basis for every electronic device used today.
With out a transistor device, there is no electronic control. Half the total number of jobs in the world would not be there. Such a fast growth in the world would not be possible at all in the last fifty years. This electronic device is controlling every other device now. In fact, human being is not controlling the electronics any more. It is the electronic controls that are controlling human beings.
