These changed the way men live - 1

What were the amazing inventions/discoveries made by humans?. There are thousands of onventions and discoveries made, but some changed the way people live . Here is my attempt to lis such discoveries which changed the people's lives.

1. Fire : Go back to Human history few thousand years back. Man was living in caves. say some where during the stone age. There is an interesting story about the fire that i read some where. Once while cave men were hunting an animal, it accidently fell in fire ( may be forest fire ). They pulled out the animal which was cooked now and found it tasty to eat. Before that he would have thought fire is dangerous now he discovered a way to make use of the same fire. of course fire gives heat which helped men to get rid of cold. And then he found out there are multiple advantages by fire when it is controlled. Man eventually discovered many things which can done using fire which mad him enter age of industry. of course he discovered he can hurt some one with the fire. . Man used the same fire power to attack his neighbour which started then and has not stopped yet.

2. Wheel : Ancient man led nomadic life used to migrate from place to place on his foot. eventually he learned to tame some animals like horses and donkeys and used them to travel from one place to another. Horses and Donkeys became means of transport for him. But something was missing. only one or two people can travel on a horse back. Perhaps initially he built a wooden plan which can carry few people and made horses drag the plank, but turned out to be tiresome for horses and time consuming as well. Then came 'Wheel'. Discovery of wheel scores more points than discovery of fire. the reason , Fire is natural phenomenon. Ancient man might have seen forest fire and used it. but was there any natural wheel ?. we find very minute number of instances in nature which resembles wheels. may be rolling stone from a mountain. may be that inspired man to use stones wheels and later it got evolved . stone wheels were replaced by wooden and finally metal wheels took over. got a cushion of rubber which were eventually filled with air. Today the use of wheel is seen everywhere. even in machine parts. There would be hardly any day one spends with out seeing a single wheel.
