what is the most important contribution ever made by a scientist?

Answer 1

Medication and vaccines!

Answer 2

In modern science the discovery of Dna and radioactivity were the latest most important discovery.
Before that The discovery and application of Electricity change the whole outlook of industry in the world.The first idea and proof that electricity did flow was by Benjamin Franklyn who was not a scientist by profession.The other was the application of Electricity which we owe to Nikolas Tesla who was not a Physisit but his ingenouity did put some scientists to gealousy. He was the great Genious behind all our modern applications of electricity .
Stephen Hawking is the most recent Scientist to have discovered the Mechanics of Black Holes which opened up a lot of Jobs for Cosmologists in the search for the Composition of the Universe.

Answer 3

I think it is the discovery of Electricity.

The history of electricity goes back more than two thousand years, to the time the Ancient Greeks discovered that rubbing fur on amber caused an attraction between the two. By the 17th century, many electricity-related discoveries had been made, such as the invention of an early electrostatic generator, the differentiation between positive and negative currents, and the classification of materials as conductors or insulators. In the year 1600, English physician William Gilbert conned the term electric, from the Greek elektron, to identify the force that certain substances exert when rubbed against each other.

While many believe Benjamin Franklin to be the father of electricity, current findings seem to show otherwise. In 1752, Franklin is said to have performed the famous experiment of flying a kite during a thunderstorm, which led to the discovery that lightning and electricity were somehow related. Modern scientists know this to be something of a tall tale, since being hit by lightning would have been fatal. It's likely that Franklin was actually insulated, away from the path of lightning.

The kite experiment helped Franklin establish a relationship between lightning and electricity, which led to the invention of the lightning rod. Benjamin Franklin went on to observe other phenomena related to electricity, but many believe that he didn't actually discover its true nature.

In 1800, Italian-born physicist Alessandro Volta constructed the voltaic pile, later known as the electric battery, the first device to produce a steady electric current. It was Volta, not Franklin, who discovered that certain chemical reactions could produce electricity. Volta also created the first transmission of electricity by linking positively-charged and negatively-charged connectors and driving an electrical charge, or voltage, through them.

It wasn't until 1831 that electricity became viable for use in technology. English scientist Michael Faraday created the electric dynamo, a crude precursor of modern power generators. This invention opened the door to the new era of electricity. A few decades later, in 1879, Thomas Alva Edison invented the light bulb.

Answer 4

hard to put all of science together and chose one thing!

but the most important thing they have in common, which i take as the most important contribution is the desire to know!

that to me is the most important contribution ever made by every scientist!

Answer 5

While it's tough to really put a finger on what exactly is the most important contribution (and to what, exactly?), there seem to be a few people who really stand out.

Probably the most obvious would be the discovery of mechanics (and with it, calculus) by Sir Isaac Newton. Today we still use his discoveries for almost any physics-related macroscopic event, and set the tone for centuries of physics development to come.

Answer 6

I would think that --the-- most important contribution was the enumeration of the Scientific Method itself.

Answer 7

F=ma, so much of our understanding is based on this simple relation.
