Humans are naturally curious and creative, two traits that have led our species to many scientific and technological breakthroughs. Since our earliest ancestors bashed a rock on the ground to make the first sharp-edged tool, humans have continued to innovate. From the debut of the wheel to the launch of Mars rovers, several of these key advancements stand out as especially revolutionary. Some inventions are thanks to one eureka moment, but most of our most pioneering inventions were the work of several innovative thinkers who made incremental improvements over many years. Here, we explore 20 of the most important inventions of all time, along with the science behind the inventions and how they came about.

1. WHEEL

Before the invention of the wheel in 3500 B.C., humans were severely limited in how much stuff we could transport over land, and how far. The wheel itself wasn't the most difficult part of "inventing the wheel." When it came time to connect a non-moving platform to that rolling cylinder, things got tricky, according to David Anthony, an emeritus professor of anthropology at Hartwick College.
"The stroke of brilliance was the wheel-and-axle concept," Anthony previously told Live Science. "But then making it was also difficult." For instance, the holes at the center of the wheels and the ends of the fixed axles had to be nearly perfectly round and smooth, he said. The size of the axle was also a critical factor, as was its snugness inside the hole (not too tight, but not too loose, either).
The hard work paid off, big time. Wheeled carts facilitated agriculture and commerce by enabling the transportation of goods to and from markets, as well as easing the burdens of people travelling great distances. Now, wheels are vital to our way of life, found in everything from clocks to vehicles to turbines.

Winning an award is the happiest and most proud moment in everyone’s life. Every achievement becomes valuable when it is recognized, and it creates history in the world. Accolades are the best motivator in everyone’s life to attain the goal without giving up. No award is small, but yes the below-mentioned awards are relatively top 10 world-famous awards.

Nobel Prize
It is a world-famous award established by Alfred Nobel 1895, the inventor of dynamite. This honor is for the contribution that has conferred the greatest benefit to humankind in the fields of physics, chemistry, physiology, social science, and peace. The first Nobel Prize was honored in 1901, in Sweden for peace, and other awards honors in Norway. Only a few people can get the Nobel Prize, but Marie curie and Frederick Sanger won more than once. This award is annually awarded and presented by Swedish and Norwegian institutions. The winner gets a 10 million SEK. Also, in India, a total of 12 people have won the Nobel Prize to date.
