The current day that we live in may seem as a result of rapid innovations and discoveries. But if we venture to trace back the facilities and machines of today, most of them are advances of devices that were built well into the past. Transportation, communication and information exchange all follow the same route of continuous innovation on an invention that dates back hundreds of years ago. Let’s look at some of the greatest inventions that revolutionized history. The Wheel (3500 BC) – Let’s Get Things Rolling Source: When we look back in history, the first invention that changed the future of mankind was the. Whether its travel or the transportation of goods, the invention of wheels made it much easier than ever before.

Wheels were not only used on vehicles in prehistoric times; they were also used in pulley systems. Surprisingly though, the application of wheels was not primarily used on carts or carriages.

Evidence suggests that they were first used as potter’s wheel in 3500 B.C. Today, wheel and its derivative are present all around us, serving us in easing our efforts and getting the job done! The Compass (206 BC) – The Pathfinder Source: Throughout the history, humans had an unquenchable thirst for exploring the unknown. But it wouldn’t have been possible without knowing the reference points that helped in identifying the geographical location.

In today’s world of satellites and GPS, it may seem irrelevant, but it was one of the key inventions that changed the world for better!

The compass was to aid in fortune telling, but its scope in travel and navigation was realized only in 11 th century AD. Waterwheel (50 BC) – The Overlooked Invention Source: Water wheels are often neglected from the most notable inventions that changed history. But let’s not forget about the first invention that helped mankind to generate power from sources other than humans and animals. The waterwheel was invented.

It converts the force exerted by flowing or falling water into mechanical energy. This mechanical energy was then used to crush grains, power lathes, drive sawmills, power textiles, forge bellows, and much more. It is reported that there was of them in Europe in 1086. Calendar (45 BC) – Save The Date Source: The modern calendar did not come into use until the 1600s, so there were many forms of calendars that were used to fill in for a unified system. The first form of the calendar used by Egyptians was the.

Then, Julius Caesar brought the Julian calendar that used a 12-month system. But, it had a major flaw as it was off by 11 minutes. The or the modern calendar we use today was introduced by Pope Gregory XIII in 1582.

Pozzolana (27 BC) – The Ancient Concrete Source: We live in a world that is built using bricks and mortar. All the buildings that stand tall from skyscrapers to even the single storied ones use the same combination of materials that keep them together without toppling over – Concrete. The invention of concrete dates back to ancient Rome. The Romans used a different combination of elements to create a binding mixture than their modern-day equivalent.

Uses an aluminous and siliceous mixture which reacts with calcium hydroxide at room temperature in the presence of water to form a substance that has cementitious properties. No wonder why Romans colosseums and cathedrals stood the test of time without losing its beauty or aura!

President who decided not to meet with the North Korean dictator only did so because they were too dumb and not savvy enough to know how to pull off a meeting with the North Koreans safely and to our country`s advantage. Bloc party another weekend in the city torrent. President since North Korea came into existence was just too dumb compared to this one. Maybe every other previous U.S.

Clock (725 AD) – the First Mechanical Clock Source: Imagine modern civilization without having a sense of time. A scenario where deadlines don’t matter nor the working hours.

Frightening, isn’t it? Time is something that helps us keep track of everything. Humans didn’t invent clock as such, as it was a redesign of the sundial. Sundials were the first devices that man used to keep track of time, and its use dates back as long as. The Egyptians and the Chinese used water clocks to keep track of time. The first mechanical clock was made by Yi Xing of China in 725 AD. The Printing Press (1450) – The Gutenberg Effect Source: The printing press is a prominent part of the foundation on which modern civilization was built upon.

It was the invention of from Germany. The machine helped to mass produce newspapers and other forms of informative pieces. It also meant that the prices on printed paper came down and it was accessible for many. The printing press served a great role in the, and by then, even the lower classes were able to afford newspapers and get to know what happened around them.

The impact of the printing press in history can’t be put together better than the words of Mark Twain himself “ What the world is today, good and bad, it owes to Gutenberg.” 8. The Steam Engine (1712) – The Invention that Started a Revolution Source: Industrial revolution kick-started with a piece of invention that powered industries and locomotives alike. It all started with the invention of the steam engine. Do not confuse his invention with the steam-powered train as it was later invention by another inventor. The Newcomen engine was stationary and was used as a stationary pump or a motor. Was the first person recorded to have created a vaccine.
