Try to imagine life without antibiotics. We wouldn’t live nearly as long as we do without them. Here’s a look at some discoveries that have changed the world. It’s impossible to rank their importance, so they’re listed in the order they were discovered.

The Copernicum System

In 1543, while on his deathbed, Polish astronomer Nicholas Copernicus published his theory that the Sun is a motionless body at the center of the solar system, with the planets revolving around it. Before the Copernicum system was introduced, astronomers believed the Earth was at the center of the universe.

Gravity

Isaac Newton, an English mathematician and physicist, is considered the greatest scientist of all time. Among his many discoveries, the most important is probably his law of universal gravitation. In 1664, Newton figured out that gravity is the force that draws objects toward each other. It explained why things fall down and why the planets orbit around the Sun.

Electricity

If electricity makes life easier for us, you can thank Michael Faraday. He made two big discoveries that changed our lives. In 1821, he discovered that when a wire carrying an electric current is placed next to a single magnetic pole, the wire will rotate. This led to the development of the electric motor. Ten years later, he became the first person to produce an electric current by moving a wire through a magnetic field. Faraday's experiment created the first generator, the forerunner of the huge generators that produce our electricity.

Evolution

When Charles Darwin, the British naturalist, came up with the theory of evolution in 1859, he changed our idea of how life on earth developed. Darwin argued that all organisms evolve, or change, very slowly over time. These changes are adaptations that allow a species to survive in its environment. These adaptations happen by chance. If a species doesn't adapt, it may become extinct. He called this process natural selection, but it is often called the survival of the fittest.

Louis Pasteur

Before French chemist Louis Pasteur began experimenting with bacteria in the 1860s, people did not know what caused disease. He not only discovered that disease came from microorganisms, but he also realized that bacteria could be killed by heat and disinfectant. This idea caused doctors to wash their hands and sterilize their instruments, which has saved millions of lives.

Theory of Relativity

Albert Einstein’s theory of special relativity, which he published in 1905, explains the relationships between speed, time and distance. The complicated theory states that the speed of light always remains the same—186,000 miles/second (300,000 km/second) regardless of how fast someone or something is moving toward or away from it. This theory became the foundation for much of modern science.

The Big Bang Theory

Nobody knows exactly how the universe came into existence, but many scientists believe that it happened about 13.7 billion years ago with a massive explosion, called the Big Bang. 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. Scientific observations seem to confirm the theory.

Penicillin

Antibiotics are powerful drugs that kill dangerous bacteria in our bodies that make us sick. In 1928, Alexander Fleming discovered the first antibiotic, penicillin, which he grew in his lab using mold and fungi. Without antibiotics, infections like strep throat could be deadly.

DNA

On February 28, 1953, James Watson of the United States and Francis Crick of England made one of the greatest scientific discoveries in history. The two scientists found the double-helix structure of DNA. It’s made up of two strands that twist around each other and have an almost endless variety of chemical patterns that create instructions for the human body to follow. Our genes are made of DNA and determine how things like what color hair and eyes we’ll have. In 1962, they were awarded the Nobel Prize for this work. The discovery has helped doctors understand diseases and may someday prevent some illnesses like heart disease and cancer.

Periodic Table

The Periodic Table is based on the 1869 Periodic Law proposed by Russian chemist Dmitry Mendeleev. He 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 and note errors in atomic weights. In 1913, Henry Moseley of England confirmed that the table could be made more accurate by arranging the elements by atomic number, which is the number of protons in an atom of the element.

X-Rays

Wilhelm Roentgen, a German physicist, discovered X-rays in 1895. X-rays go right through some substances, like flesh and wood, but are stopped by others, such as bones and lead. This allows them to be used to see broken bones or explosives inside suitcases, which makes them useful for doctors and security officers. For this discovery, Roentgen was awarded the first-ever Nobel Prize in Physics in 1901.

Quantum Theory

Danish physicist Niels Bohr is considered one of the most important figures in modern physics. He won a 1922 Nobel Prize in Physics for his research on the structure of an atom and for his work in the development of the quantum theory. Although he help develop the atomic bomb, he frequently promoted the use of atomic power for peaceful purposes.

Atomic Bomb

The legacy of the atomic bomb is mixed: it successfully put an end to World War II, but ushered in the nuclear arms race. Some of the greatest scientists of the time gathered in the early 1940s to figure out how to refine uranium and build an atomic bomb. Their work was called the Manhattan Project. In 1945, the U.S. dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki. Tens of thousands of civilians were instantly killed, and Japan surrendered. These remain the only two nuclear bombs ever used in battle. Several of the scientists who worked on the Manhattan Project later urged the government to use nuclear power for peaceful purposes only. Nevertheless, many countries continue to stockpile nuclear weapons. Some people say the massive devastation that could result from nuclear weapons actually prevents countries from using them.

HIV/AIDS

In 1983 and 1984, Luc Montagnier of France and Robert Gallo of the United States discovered the HIV virus and determined that it was the cause of AIDS. Scientists have since developed tests to determine if a person has HIV. People who test positive are urged to take precautions to prevent the spread of the disease. Drugs are available to keep HIV and AIDS under control. The hope is that further research will lead to the development of a cure.

Science has really helped the world,can't imagine a world without it,maybe by now,I would be in garden of Eden,chasing squirrels with carved stick.

Wow good... I might agree with some of them but as for the big bang theory, even if I'm tied with a nuclear bomb and thrown into the pacific ocean, I will never believe that bullcrab story.


The big bang theory and Evolution, none accurately and comprehensively explains the Origin of Man and water, not animals, I mean man and water. Especially the concept of life and death, how was the first man formed and why are others not formed that way. All those rubb!sh archaelogical stories of Australopithecus, Homo habilis,Homo Erectus mumbo-Jumbo.


Creationism has a much better explaination. God created the Universe, and everything in it.

And why a topic as enlightening as this is yet to make the frontpage beats my imagination.

If to say na Tonto Dike mess wey person post am as topic, we for don see am for front page.

O ma shey o!!!

This is the most awesome of all discoveries.

I dey come first... Make I trek back go read the story

Modified**

Ehen... I don waka come back so as I don read am finish. As me see so for the plenty 14 points wey dey there so, na only Electricity the ogbonge no 3 point wey dey very very important to me sotay if to say dem no find am so, I for no fit dey charge this my Tekino P5 take dey chat WhatsApp, dey do BBM, dey enter Nairaland, FaceBook, Twitter, Eskimi, 2go and the other plenty plenty ones.

So me dey salute Michael Faraday wellu well dey tell am thanku you for this wonderful invitation and innovative innovation. Later, I go give you my own Nobel Prize Laureate...!

if u remove science from the world......what u have left is crap......

everything work for good.

l prefere garden of eden oooooooo

This are the scientist that make science students ve sleepless night.

Everything is nice except that quantum theory

damola u don make front page niyen o

I wonder how life would have been so boring and difficult without science , science has made life easy and interesting. God bless science .

Selfies should be there too and Butt Implants.

This our generation sha.

macsika: Wow good... I might agree with some of them but as for the big bang theory, even if I'm tied with a nuclear bomb and thrown into the pacific ocean, I will never believe that bullcrab story.

Bloody creatard.

Ok

Science! Hmmm. So sweet and yet a bit complicated.

I wonder how life would be without science

Anyone who believes that Big Bang Theory should have his or her head examined..

The person who came up with that idea was high on some serious weed!!..... everything in the world came from a dot?!!.......even a baby would look and you and shake It's head

No be lie shall.

NHh

Creation has a much better explanation? don't confuse better for simple.. Creation has a much simpler explanation not a better one..

Ur head corret so?

ayusco85: .

Scientist make the world easier, scientist minus world is zero...

U well so

ichidodo: bb

Op.. /Thumbs up/

I don't believe and will neva believe in the " The Big Bang Theory " because God created Heaven and Earth


So say anoda fink

my questions about the big bang is: where did the little ball come from? how long was it there? where was its location? if it was a particle ball, how come it underwent implosion/explosion?

I still believe the greatest discovery was electricity,,it is d stil d bedrock of other discoveries.We must giv kudos 2 all who sacrificed their lives 4 us 2 enjoy dis present world we re living in
