Ten most important scientific discoveries
Talking about ten most important scientific discoveries, we will begin by asking a question. Can you imagine the world without medicines and antibiotics? Diseases that have been now eradicated most of all like Polio, Bubonic, Typhus, were epidemics at one point. Ailments that killed human beings have a cure only because of the persistence and hard work of man. However, that is not all. There is much more to scientific discoveries and inventions, beyond just medicines and antibiotics. There’s the Physics, the Chemistry, Scientific Phenomena and much more! In this article, let us look at 10 such game changing scientific discoveries of man.
The Copernicun System
On his deathbed, Polish astronomer Nicholas Copernicus published his theory that the sun is at the center of the solar system, with the planets revolving around it. Before the Copernican system was introduced, astronomers believed the earth was at the center of the universe. If not for this, we’d still go around thinking that the sun revolves around the earth rather than the other way round.
In 1664, Isaac Newton, an English mathematician and physicist Newton figured out that gravity is the force that draws objects toward each other. As a result, law of gravitation came to be known. If not for gravity, I wonder if we could figure out how to go to the space.
Michael Faraday discovered that when a wire carrying an electric current is placed next to a single magnetic pole, the wire rotates. He therefore produced an electric current by moving a wire consequently through a magnetic field, creating the first generator. As a result, his discovery revolutionized the entire electricity generating process.
Charles Darwin, the British naturalist, came up with the theory of evolution. It states that all organisms evolve very slowly over time. Due to these changes allow a species to adapt and survive in its environment. If a species doesn’t adapt, it may become extinct. He therefore, called this process natural selection. It’s often called the survival of the fittest. It was this discovery that helped us finally reach an acceptable line of conclusion regarding how humans probably came into being.
Before French chemist Louis Pasteur began experimenting with bacteria in the 1860s, people did not know what caused disease. He discovered that disease came from microorganisms and that bacteria could be killed by heat and disinfectant. Most relevantly, doctors now sterilize their instruments saving millions of lives from epidemics of past!
Theory of Relativity
Albert Einstein published the theory of relativity in 1905. It furthermore explains the relationships between speed, time and distance. The complicated theory states that the speed of light always remains the same—300,000 km/second regardless of how fast someone or something is moving toward or rather away from it. Not just that, relativity became one of those philosophical understandings which could bring into perspective therefore brought much more about life than mere physics!
The Big Bang Theory
In 1927, Georges Lemaître proposed the Big Bang theory of the universe. The theory says that all the matter in the universe was originally compressed into a tiny dot. In a fraction of a second, the dot expanded, and all the matter instantly filled what is now our universe. The event marked the beginning of time. As a result, scientific observations seem to confirm the theory.
Antibiotics are powerful drugs that kill dangerous bacteria in our bodies curing disease. Alexander Fleming discovered the first antibiotic, penicillin, which he grew in his lab using mold and fungi. Most noteworthy with this game changer that the entire human civilization consequently found a higher life expectancy and protection against almost many bacterial infections that were most probably yet fatal.
On February 28 1953, James Watson of the United States and Francis Crick of England basically discovered the double-helix structure of DNA. Furthermore, DNA became the most important segment of the human beings.
Russian chemist Dmitry Mendeleev had noticed that, when arranged by atomic weight, the chemical elements lined up to form groups with similar properties. He was able to use this to predict the existence of undiscovered elements.
Therefore in conclusion, at http://www.projectsforschool.com, we decided to bring to you some interesting snippets from the world of science. This article seems like has covered these amazing discoveries; man wouldn’t be leading a comfortable and long life. Furthermore, we have the previous generations to thank for these discoveries. They have transformed our entire life!! Keep a watch on this section for more such interesting pieces!
