Transcript of Top 10 Scientific Discoveries

Nuclear Fission
Nuclear fission was founded by Otto Hahn in 1938 by looking at the fission in atoms and the outcome if atom was split. He discovered that if a high speed neutron was absorbed a fissionable material, it would react and split into 2 lighter elements and release 3 neutrons which creates an extreme amount of energy that is millions of times more power than conventional methods. Nuclear fission is one of the most important scientific discoveries because of the unlimited potential that it has, it can create so much energy without as much of a by product like fossil fuels has. Nuclear power has helped revolutionize the world and will continue as long as the world has a need for energy.
Theory of the Big Bang
This theory states that the the birth of the universe was created by one dense singularity at one point in space which began to expand to create the universe that we know, it is still expanding to this day. This theory was first introduced in 1927 by Georges Lemaitre and has been accepted into the scientific society and has plenty of evidence to support its existence. This deserves to be on the list because with this theory we have now a better understanding of our expanding universe and will allow us to keep discovering new things about it.
Ohm's Law
Published in 1827 by Georg Ohm, Ohm's law is used to calculate the ampheres, volts, and resistance though many different circuits and the relationship between them. Also, he tested it through different length of wires. Ohm's law is used in many places in the modern day, like in a generator plants where they regulate the resistance of the flow of electrons, amount of voltage, and amps. This deserves to be on this list because it allows us to do a lot of wiring in homes and buildings and also transfer electricity to many different places
Theory of Evolution
In 1950 Charles Darwin created the Theory of Evolution which showed us how all species on earth adapted and how they survived by adapting themselves through the changing environments that they live in. If the species does not adapt it will die out like the other 99.99% of species that ever lived on earth. Darwin called this process natural selection. This deserves to be on the list of top 10 scientific discovers because this has taught us how every creature on earth will change everything about themselves just to survive.
The Copernicum system
In 1543 Nicholas Copernicus developed a theory of how the sun was the center of the solar system and that all the plants revolve around the sun. He was able to disprove that the earth was the center of the universe, which was a very important opinion at the time. This is one of the most important scientific discoveries because before this we were not able to understand simple things like the seasons, coronal mass ejections, and a lot of other space discoveries.
Top 10 Scientific Discoveries
Newton's 3 laws of Motion
Sir Issac Newton created the three laws of motions in 1686, he discovered 3 very important laws of motion. First of all, an object at rest stays at rest and an object in motion stays in motion until acted upon by an outer force. Secondly, The amount of movement is affected by the amount of force exerted on the object. Thirdly, every action has an opposite and equal reaction. These discoveries are extremely important because they have helped the modern world create many different things like space travel, vehicles, and many other important inventions.
Paleontology
In 1666 Nicolas Steno discovered that fossilized remains of animals in stone were not the work of the gods or by demons. He discovered that they were dead remains of animals that had been buried in the earth millions of years ago. By comparing some of them to a large shark tooth that had been given to him, he was able to confirm his theory that these were animals that had lived long ago. With this discovery he had laid the foundations for the first paleontologists.
Periodic table
Dmitri Mendeleev organized the very first periodic table in 1863. With his periodic table he was able to predict certain characteristic of new elements that were to be discovered, at first his science was discredited but not soon after the element germanium was discovered and it fit exactly where he predicted it would fit in the periodic table. This discovery by Mendeleev has helped us discover many other elements and we still use his characteristic labeling to discover new elements.
Atmospheric pressure
Atmospheric pressure is the weight of air on the surface of the earth. It was first discovered by Evangelista Torricelli in 1643 when he was recreating an experiment he had conducted with Galileo 3 years before. He discovered that atmospheric pressure rises when there is a storm and changes back afterward, he had discovered that the atmosphere had a weight. With his scientific discoveries he had invented the barometer.
Law of Universal Gravity
In 1664 Sir Issac Newton created the Law of Universal Gravity which he used to prove that gravity is an invisible force that keeps us held to ground and that it keeps us in orbit with the sun. This is one of the most important scientific discoveries of all time because without the Law of Universal gravity we would not be able to go to space and do a lot of things that we are able to do now.
