The Top 10 greatest scientific discoveries that change the world. 



All scientific discoveries are wonderful, and some discovery are totally change their life style . Now a days our living style is totally digitalized. Each and every things that comes under the science and their laws .

Here, I didn’t choose the modern inventions, which could easily fill its own list. And it’s not far for this blog. So, I choose the top 10 greatest discoveries that give highly impact to their human life.

While some change happens automatically, like the tides going in and out, some changes bloomed from scientific discoveries.

Using fire to cook food and keep warm propelled our ancestors toward the foundations of early settlements and continued the growth of civilization. Using fire to shape metals for weapons and building materials led to more and more discoveries and more and more advancements. While many advances shaped humanity, we’ve focused on ten significant scientific discoveries that changed the world.

10.electricity ;

Benjamin Franklin is credited for discovering electricity in the 1700s with his kite experiment, in which he flew a kite with a metal key tied to it during a thunderstorm.


In science, electricity and its history is a fascinating topic that can help your children understand how life has changed because of electricity.

Electricity is not only an indispensable source of energy for the development of societies, it is also the easiest energy to use, thanks to its versatility. Thanks to the installation of cable networks, it is possible to bring it to a large number of towns and villages. Similarly, it reaches long distances and is capable of supplying energy to isolated areas.

On the other hand, research and constant development in artificial lighting have led to increasingly sustainable solutions to improve energy efficiency. Likewise, without electricity, most of today’s technological advances, such as network connectivity, could not have happened.

Scientific laboratories have also used electricity as a source of development and innovation, such as electrolysis, which allows elements of chemical compounds to be broken down by the application of electric currents.

Impact ; electricity plays a crucial role in various aspects of modern life, such as industry, communication, and transportation . It is essential for the operation of processing plants, providing power for pumps, compressors, refrigeration plants, lighting, control systems, and computers .

9. Internet;

what is the Internet? The answer must sound very easy however, most people won’t be able to answer it. The Internet is a global network of interconnected computer networks that communicate with each other over the Internet Protocol Suite (TCP/IP). It is a network of networks made up of private, public, academic, and government networks ranging from local to global in extent and connected by a diverse set of electronic, wireless, and optical networking technologies.


Impact ;The Internet holds a huge range of information as well as services like Email, Voice-over IP, Television, Games, File Sharing, Shopping, etc.

8.CSISPR;




CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats. The CRISPR/Cas, it’s easy to disrupt a targeted gene, or, if a DNA template is added to the mix, insert a new sequence at the precise spot desired. The method has profoundly changed biomedical research, as it greatly reduces the time and expense of developing animal models with specific genomic changes. Scientists now routinely use the CRISPR/Cas system for this purpose in mice. And for human diseases with a known mutation, such as cystic fibrosis, it’s theoretically possible to insert DNA that corrects the mutation. There are clinical applications in human trials now, including for engineering T cells outside of the body for CAR-T cancer therapy and for editing retinal cells for leber’s congenital amaurosis 10, an inherited form of blindness

Impact ;

  • CRISPR help prevent diseases like HIV and cancer, make crops more hardy, and tackle the climate crisis. But there are still concerns around genetic modification, and the use of gene editing in crops is regulated in many countries.
  • CRISPR-Cas9 can be used to target and modify “typos” in the three-billion-letter sequence of the human genome in an effort to treat genetic disease.

7.DNA ;

DNA, organic chemical of complex molecular structure that is found in all prokaryotic and eukaryotic cells and in many viruses. DNA codes genetic information for the transmission of inherited traits.


The chemical DNA was first discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943.In February 28, 1953, James Watson and Francis Crick discovered the structure of DNA, the double helix. Their discovery helped unlock the mystery of our genetic code. That breakthrough led to significant advances in scientists’ understanding of DNA replication and hereditary control of cellular activities.

Impact ; DNA carries the instructions for the development, growth, reproduction, and functioning of all life. Differences in the genetic code are why one person has blue eyes rather than brown, why birds only have two wings, or why giraffes have long necks.

6.periodic table ;

A table in which the chemical elements are arranged in order of increasing atomic number. Elements with similar properties are arranged in the same column (called a group), and elements with the same number of electron shells are arranged in the same row (called a period).


A number of other chemists before Mendeleev were investigating patterns in the properties of the elements that were known at the time. The earliest attempt to classify the elements was in 1789, when Antoine Lavoisier grouped the elements based on their properties into gases, non-metals, metals and earths. Several other attempts were made to group elements together over the coming decades. In 1829, Johann Döbereiner recognised triads of elements with chemically similar properties, such as lithium, sodium and potassium, and showed that the properties of the middle element could be predicted from the properties of the other two.

5.gravity ;

Gravity is one of the fundamental forces of the universe. Every object that has mass exerts a gravitational pull or force on every other mass. The strength of this pull depends on the masses of objects at play. Gravity keeps the planets in orbit around the sun and the moon around the Earth.


In 1687 , sir Isaac Newton who discovered gravity . At the time he sitting under the Apple tree, he noticed that the Apple falling down. Then he tried to figure out why the Apple came down. Even through the Apple goes up or any other direction. On that time he confirmed the unknown force play a major role on it. Newton named that force gravity. And his theory is called Newton’ law of Universal Gravitational.

Later in the early 20th century, Albert Einstein developed a whole new idea about gravity. According to him, gravity is the warping of space and time.

Some object are work against the gravity principles. Like helium gases 

Impact ;

  • Objects fall toward the centre of the Earth due to the force of gravity. (Free fall object) 
  • celestial bodies of comparable mass interact gravitationally (the centre of mass of the two bodies).
  • The force of gravity can theoretically act on any two mass objects.

4.earth motion ;

Earth in motion refers to the understanding that Earth is not stationary but moves in different ways. Earth rotates on an axis and revolves around a star.



Earth rotation :Earth rotates on its axis, which is an imaginary line running from the North Pole to the South Pole. This rotation is responsible for the day-night cycle, with one complete rotation taking about 24 hours

Earth revolves ; The Earth revolves around the Sun, completing one orbit approximately every 365 days. This revolution, combined with the tilt of the Earth's axis, leads to the changing seasons.

We didn’t feel the earth rotation because of the earth including the ocean and atmosphere, and we are all spinning along with the earth at the same constant speed. If earth suddenly increase the speed or decrease the speed. Then we definitely notice the feel it.

3.Antibodies and penicillin ;

Generally ,we use the most of the medicine are antibiotics example ; Amoxicillin, Azithromycin.



Antibiotics are medicine, that fight against the bacterial infection. It doesn’t work on any other infection like virus, fungus and yeast infection. Now a days antibiotics in different form like pill, capsule, cream , drops, ointment, injection etc,,.

In early century the people didn’t know the causes of disease. At the time people use plant and animals extract used to treat the some infection . During 19th – 20th Century the people know that we now consider straightforward to treat – such as pneumonia and diarrhoea – that are caused by bacteria.

Alexander Fleming was, it seems, a bit disorderly in his work and accidentally discovered penicillin. Upon returning from a holiday in Suffolk in 1928, he noticed that a fungus, Penicillium notatum, had contaminated a culture plate of Staphylococcus bacteria he had accidentally left uncovered. The fungus had created bacteria-free zones wherever it grew on the plate. Fleming isolated and grew the mould in pure culture. He found that P. notatum proved extremely effective even at very low concentrations, preventing Staphylococcus growth even when diluted 800 times, and was less toxic than the disinfectants used at the time.

Impact ; 

  • The antibiotics cure life threading diseases. 
  • The antibiotics help the model medical procedures. 
  • It helps to treat cancer , organ transplant and surgery


2.painkiller:

Painkiller is a drug that used to reduce or remove the pain in our body. The body secret some chemical against the pain naturally is natural painkiller.


Pain is the ultimate teacher. It teaches us to avoid fire, poison, sharp objects and many other things that could cause us harm. It alerts the body to injury and disease.
In 16th – 18th century the various form of opium has been used as painkiller or sleep .After that ether and chloroform were introduced as anesthetics for surgery. By the 1900s, morphine and heroin came into use as pain medications.

The most powerful prescription painkillers are called opioids. Opioids have been used for thousands of years to control pain, with their first use in the form of opium until morphine was developed in 1803. After the hypodermic needle was invented, morphine was widely used to treat soldiers with painful traumatic injuries.

Impact : the painkillers are most useful in ancient times to relieve the child birth pain, mensuration pain, injury of soldier.

1. Vaccine ;

Vaccination is a simple, safe, and effective way of protecting you against harmful diseases, before you come into contact with them. It uses to improve body’s natural defenses to build resistance to specific infections and makes your immune system stronger.




Vaccines train your immune system to create antibodies, just as it does when it’s exposed to a disease. However, because vaccines contain only killed or weakened forms of germs like viruses or bacteria, they do not cause the disease or put you at risk of its complications.
 1796, English physician Edward Jenner expands on this discovery and inoculates 8-year-old James Phipps with matter collected from a cowpox sore on the hand of a milkmaid. Despite suffering a local reaction and feeling unwell for several days, Phipps made a full recovery.

Two months later, Jenner inoculates Phipps with matter from a human smallpox sore in order to test Phipps’ resistance. Phipps remains in perfect health, and becomes the first human to be vaccinated against smallpox. The term ‘vaccine’ is later coined, taken from the Latin word for cow, vacca.
 further step by step the scientists take over the research about vaccine and vaccination. In 1872, despite enduring a stroke and the death of 2 of his daughters to typhoid, Louis Pasteur creates the first laboratory-produced vaccine: the vaccine for fowl cholera in chickens. again the 1885, Louis Pasteur successfully prevents rabies through post-exposure vaccination.

Impact :

The vaccine save the millions of people life against the life threading diseases.

• World Health Organization (WHO) European region release the blog December 2020 , COVID -19 vaccine have reduced death due to pandemic by least 57% saving more than 1.4 million lives.
• The vaccines reduced deaths by 57% overall (CAT range: 15% to 75%),
