Scientific Discoveries That Changed the World

Updated on April 7, 2019


Over the course of human history we have countless discoveries that have improved the quality of our lives and help to understand the world around us.
It is very difficult if not impossible to rank the importance of these discoveries that we have made but one thing is for sure some of them have literally changed our lives from Penicillin to X-rays.
Here we will discuss the biggest scientific breakthrough in human history.

History of Scientific Discoveries

Alexander Fleming a Washington scientist if had not discovered penicillin the first antibiotics in 1928 we would probably be dying from things like Stomach ulcer, Strep throat, Scarlet fever, Staph infections and Leptospirosis.

Life changing scientific breakthrough discovery was electricity which was discovered by Michael Faraday. His main discoveries included the principles of electromagnetic induction, diamagnetism and electrolysis. Faraday's experiments also created the first generator which was the forerunner of huge generators that produced our electricity today.

Deoxyribonucleic Acid (DNA):

Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s.
But in fact it was first identified in the late 1860s by the Swiss chemist Fredric Miescher. Then in the decades following Miescher's discovery other scientists carried out many research studies and help us to understand how organisms pass on their genes and how working of cells are covered.

Theory of Relativity:

Encompassing two inter related theories by Albert Einstein, special relativity and general relativity, the theory of relativity published in 1905 completely transformed theoretical physics and astronomy during the 20th century.
So proceeding our two hundred years old theory of mechanics created primarily by Newton. This theory became the foundation for much of modern science.

Periodic Table:

In the year 1869 the Russian chemist Dmitri Mendeleev noticed that when arrange by atomic weight the chemical elements lined up to form groups with smaller properties. With this knowledge he was able to create the first periodic table, one of the most important discoveries in history.

Theory of Evolution:

Although this theory is a bit controversial one because still a lot of debate is about the theory of evolution by natural selection.
Inspired by an observation that he made on the second survey voyage of the beagle in 1831 to 1836 Charles Darwin began to develop what later became known as the theory of evolution by natural selection, the key mechanism of evolution. Regardless of whether not you believe natural selection is scientific there is no doubt that this has really shifted the course of science our world today.

First Edited Human Embryo:

In scientific breakthrough of 21st century the scientists successfully edited the first human embryo ever in the United States in July 27th 2017. Researchers in Portland Oregon have achieved a significant breakthrough in gene editing technology. Taking advantage of the revolutionary gene editing technique, CRISPR a gene link to hard conditions was successfully deleted from a human embryo.

Alien Planet:

The scientists have discovered the alien planet that is the best candidate for life as we know it. Scientists of the European Organization for astronomical research of the ESO found the best candidate for extraterrestrial life for human beings. The super earth name LHS 1140b was found in the habitable zone of a dim star 40 light years away from Earth. It receives about half as much sun light from its star LHS 1140 as the Earth does from the Sun.

Gravitational Waves:

Gravitational waves proves the theory of general relativity. Albert Einstein's theory of general relativity states that space and time are unified in one quantum, usually commonly refer to as space time quantum. Objects in the universe, no matter their size, orbs space time as they move creating ripples known as gravitational waves. Until recently however that theory was just a theory but new technological advances allow astrophysicists to measure the massive gravitational waves created by huge objects in deep space. Usually these come from black holes and neutron stars millions and millions of life years away so their waves are incredibly faint by the time they reach earth.

Growing Human Organs in Pig:

Scientists at the SALK institute for biological studies in California said they are one step closer to being able to grow human organs inside pigs. In their latest research they were able to grow human cells inside pig embryos, a small but promising step towards organ growth. A question in minds may rise that why would anybody want this research done in the first place? well scientists say it could help with studying disease and help develop different drugs. It could be a way to help with human organ donation.
