...ingenuity because it solved the problem of people not being able to tell and measure the time accurately. It helped people manage their time more efficiently and allowed creation of easy to understand different time zones. Without the invention of the clock, we would not be able to know the time or set an amount of time to a piece of work. In today’s life measuring time accurately is so important that most of the invention and modern procedures (like computer controlled manufacturing, ... -

Clock
The clock was invented in the 1300's by Khalaf-al-Muradi. It is a mechanical device that can display time in 24 hours. The clocks became more accurate after the discovery of the pendulum. It changed the world because prior to the invention of clock one could only estimate the rough time at a location based on Sun or star’s position depending on whether it was day or night. Clocks enabled people to know exact time which could be used as a standard reference by all. This is an example of human... -

Hell
Dante wrote "The Inferno" in 1302. It is a poem about Dante travelling through hell. Dante's Hell had 9 circles and in each one, the punishment was more severe than the last circle. It depicted different types of sins have different punishments. It changed the world because the church's story was now strengthened and more people started believing that if they did something wrong, they would go to hell. Its significance today is that people believe in hell the way he had perceived. Many of the... -

and official documents. It could take years just to copy one book. The invention of the printing press helped the knowledge to spread faster than ever before. Without this people would not have had access to the knowledge contained in books. The contribution to so many fields (like sciences, maths, commerce, literature, philosophy etc.) would not have been what it is but for the creation of printing press. Many of the revolutions of the world wouldn’t either have been or wouldn’t have had such.. -

...as during that time plenty of gold and silver was found here. They also introduced Christianity (Catholicism). Europeans diseases like small pox and measles killed lots of local population in this region. Spain's empire brought new ideas to Europe, and led to inflation. Therefore this event is very important in shaping the course of history and changed Spain and Americas forever.

New World
In 1492 Christopher Columbus (Born in Italy) while on exploration (Spain funded) to East Indies, reached the new world- known today as Americas. Though Columbus was not the first European explorer to reach the America but it was his voyages that started European contact with America in a major way. It changed the world as it started an era of European exploration and colonization of foreign countries that lasted for several centuries. Spanish explorers conquered most of Mexico and Latin America. -

Pocket Watch
The pocket watch was invented in 1505 by Peter Henlein. The pocket watch is a mechanical device that can measure time and it is small enough to be carried in a pocket. It changed the world because after the invention of the pocket watch, people could take the watch and know the time of the day whenever they wanted to. This let people be aware of exact time whenever they wanted to leading to much better coordination and time management amongst people. This is an example of human ingenuity... -

New way of ruling
Nicollo Machiavelli wrote "The Prince" in 1513. It is a book about the way Machiavelli thinks rulers should rule. It changed the world because he tells people about his thought "The end justifies the means" as a story. This means that, as a leader, you should do what is better for the majority even if it means some harm to others. He also thought that as a leader, it is better to be feared than to be loved but you should avoid hatred. The book has provided many thoughts on how to... -

Heliocentric View
Nicolas Copernicus was the first person to discover the heliocentric view in 1514. This is the idea that the earth revolves around the sun. It changed the world because it changed the way we knew earth as till now the common understanding was that earth is the centre of the universe. Not only this but with this and the subsequent studies and experiments based on this, we have a better knowledge about many natural phenomena like day and night, changing weather, eclipses and many acts of nature... -

Thermometer
The thermometer was invented in 1593 by Galileo Galilee in Italy. This thermometer was different from the ones we know now, because it had a coloured fluid and air in it. As the air expanded, the fluid would go down. Thermometer allowed measurement of temperature. It changed the world because it allowed scientists to study as well as control various processes / things around us and understand the reasons behind them and exploit these to bring more and more conveniences for human beings. This... -

Telescope
The telescope was invented in 1608 by Hens Lippershey though later Galileo also independently made a telescope. It is a device that uses an arrangement of transparent lenses to manipulate light from the distant objects in such a way that they seem closer. It changed the world because it let scientists study our solar system and other distant objects in the universe to understand it better and also explain various phenomena on earth based on these studies. It changed our view of the universe... -

Match
The match was invented in 1680 by Robert Boyle. The match is a device that can be used to create fire. Phosphorus and sulphur when rubbed together became a flame and that is what the match did. It changed the world because human being had got used to using fire for its such basic need as cooking food and the conventional way of creating it by rubbing wooden sticks on stone was unreliable and unpredictable. Creation of fire by a match box brought the convenience of lighting it anywhere, ... -

Submarine
The submarine was invented in 1624 by Cornelius Van Drebbel. The submarine is devices that can go underwater with people in it continue being under the water for extended time and travel some distance if required. It changed the world because it allowed people to study under water environments especially oceans in great details. But most significantly use of submarine in wars allowed the navies possessing it to go undetected and attack from under the water the enemy navies. This is an example... -

This is an example of human ingenuity because the quest to be able to go under the water for an extended time to find alternative to floating above the surface of water was answered with this invention. It has been put to many scientific and military uses which indirectly has affected entire world. The outcome of the World War II could be very different without the submarine. It has changed the course of history and warfare forever. -
Blood Circulation continued
...was believed to be transformed food made in the liver and that it was consumed by the tissues, not recirculated. Without this knowledge, the medical sciences would have not developed so much and its life-saving ability would have been severely affected eg. the heart surgeries which are saving so many lives would not have been possible resulting in human mortality rate to go up. This was the base for all modern research on the heart and blood vessels. -

Blood Circulation
The detailed and systematic circulation of blood was described by William Harvey an English physician. He also discovered that heart pumps blood to the body. In 1628 he published his completed treatise on the circulation of the blood, the De Motu Cordis. It changed the world because for the first time the circulation of blood was understood properly and his findings are valid till date. Before this blood was believed to be transformed food made in the liver and that it was consumed by the... -
Adding Machine
The adding machine was invented in 1642 by Blaise Pascal. It was a mechanical device that could add two numbers faster than the human mind. It changed the world because it allowed fast computation of mathematical problems and was the foundation for modern day cash registers, calculators and computers. This is an example of human ingenuity because it was a result of continuous creativity and imagination of scientists to be able to do things faster, better and take bigger challenges. -
