20.Radio

The noun radio is also used to mean a broadcast radio receiver. Radio waves were first identified and studied by German physicist HenrichHertz in 1886.The first practical radio transmitters and receivers were developed by Marconi,and radio began to be used commercially around 1900.
19.Boats
Boats have been used as a form of transportation for.overr 40,000 years…The first boats were made in the early centuries human society. They were logs hollowed out used as canones used for fishing by the cave people.Later on boats would evolve into rafts,then large deadly fighting machines.
18.Concrete
In 200 BC,the Roman’s successfully implemented the use of concrete in the majority of their construction.But they weren’t the first to create concrete They used a mixture of volcanic ash,lime,and seawater to form the mix.Modern concrete is typically mixture of silica,sand,limestone clay,chalk and other ingredients.
17.Telegraph
Telegraph system spread across the world,as well…Rather than taking weeks to be delivered by horse and carriage mail carts,price of news could be exchanged between telegraph stations almost instantly.The telegraph also had a profound economic effect allowing to be “wired across great distances”.It was invented by Samuel Morse in 1837.
16.Vaccine
The smallpox vaccine is the first vaccine to be developed against a contagious disease.In 1796,the British doctor “Edward Jenner” demonstrated that an infections with the relatively mild cowpox virus conferred immunity against the deadly smallpox virus.
15.Compass
The compass changed this trade and communication network so quickly that it isn’t even certain whether the chinese or Europeans made the first compass. The compass provided all-weather orientation for travelers; this easily cut many travel.times in half and opened other trade routes that were formerly unnavigable
14.Pencilin

The first name for pencilin was “mouldjuice”.It was accidentally discovered by Scottish bacteriologists “Alexander flemming” in 1928.The discovery of pencilin changed the world of medicine enormously with its development, infection that were previously severe and often fatal, like bacterial endocarditis,bacterial meningitis and pneumocoical pnemonia could be easily treated.Pencilin cleared that way in that future.
13.Automobiles
Automobiles are made the great impact on society. It makes our travel very easy. It reduces our time for so many hours.Infact nowadays days in cities every whose has a vehicle eventhough in the village the automobiles made a great impact in agriculture and for transport.
12.Internet

The material was made finer over the centuries, was treated across Asia and was used in the first paper money from the early 12 th century C.E.
10.Internal Combistion Engine
Agricultural production improved greatly with the development of a tractor and other farm machinery powered by the internal combustion engine. The development of the engine also gave oil producing countries a wealth and an influence in world affairs that they had not previously possessed.
09.Bronze
The Bronze age started in the 3rd millennium b.c.It brought great advancements in the world.The tools and weapons of the day were soon made stronger and more durable.Bronze is harder than copper,making it useful for tools and weapons.It can be sharpened.

06.Zero
Zero helped merchants to balance their books, an essential part of successful trade, It allowed scholars to invent algebra and calculus, which are central to physics, engineering and medicine. Zero was also key to inventing computer.
05.Transistors

Transistor transformed the world of electronics and had a huge impact on computer design. “Wiliam shockley, John bardeen, Walter houser brattain” are the inventors of transistors. It is made of semi conductors replaced tubes in the construction of computers.
04.Stream engine

The steam engine helped to power the industrial revolution. It was invented by “James watt” . Before steam power, most factories and mills were powered by water, wind, horse, or man. Steam power allowed for factories to be located anywhere. It also provided reliable power and could be used to power large machines.
03.Bulb

The invention of the light bulb changed the world from dark to bright, It also changing the social and economic structure of society and bringing other appliances into the home. It lighting changed the structure of society, allowing activities to extend into the night.
02.Printing Press
