Greatest Scientists in the 20th Century

Science in the 20th century has advanced dramatically. There was a huge amount of technologies that were developed in the 20th century such as the worldwide web, penicillin, television, transistor, DNA profiling, and the microprocessor. These brilliant inventions were created at the end of the 19th century but they were universally used and perfected in the 20th century. The first television and computer were made during the 20th century and it forever changed the dissemination of information and communication. But all of these would not be possible without these brilliant minds. Let’s take a look at the greatest scientists in the 20th century and how they’d change the world forever.

1. Stephen Hawking

Stephen Hawking was an English author, cosmologist, and theoretical physicist. He was the Director of Research at the Centre of Theoretical Cosmology at the University of Cambridge. Hawking’s was known for his studies about black holes. He formed the theory called “Hawking radiation” where he said that black holes emit radiation and he became the first person to set forth a cosmology that is explained through a union of the general quantum mechanics and thetheory of relativity. When Hawking was 21 years old, he was diagnosed with a rare condition called Amyotrophic Lateral Sclerosis which left him almost completely paralyzed.

2. Albert Einstein

The 19th century did not only witnessed the birth of Albert Einstein, but it also witnessed the birth of modern physics. Einstein is known as the father of modern physics and his numerous works include the photoelectric effect which established the quantum theory within physics and the general theory of relativity. He also won several awards such as Max Planck medal, Copley medal, Matteucci medal, and a Nobel Prize in Physics.

3. Alan Turing

Alan Turing was a logician, philosopher, cryptanalyst, and computer scientist that was born in London, England. If it wasn’t for him computers would probably not exist because he invented the Turing Machine which is a simple but capable machine that can decipher any form of algorithms that can be measured and quantified. Turing and his team of code-breakers managed to defeat the German’s machine called “Enigma” because of his machine.

4. John Forbes Nash Jr.

Josh Forbes Nash Jr. was an American mathematician who is known for conducting the Game Theory and differential geometry and these studies were widely used in the field of economics, politics, accounting, and even biology. But it was the Game theory that earned him a Nobel Prize.

5. Sigmund Freud

Sir Tim Burners-Lee is an English computer scientist and engineer. He is best known to invent one of the most revolutionary inventions of the 20th century, the World Wide Web. Sir Tim Burners-Lee is a qualified software engineer who was working at CERN when the idea of creating the global network system came into his mind. He is also the creator of the world’s first web browser and editor.

7. Richard Feynman

Richard Feynman was an American theoretical physicist who is famous for his work entitled The Principle of Least Action in Quantum Physics which served as the foundation for his Nobel Prize winning work on quantum electrodynamics. His other famous work was the Feynman Lectures of Physics which is one of the most popular physics textbooks.

8. Francis Harry Compton Crick

Francis Harry Compton Crick was a British biophysicist, molecular biologist, and neuroscientist. He was popularly known for co-discovering the structure of the DNA molecule along with James Watson and Maurice Wilkins. They were awarded a Nobel Prize for Physiology and Medicine for discovering the molecular structure of the DNA and its significance for information transfer in living material.

9. Frederick Sanger

Frederick Sanger was a British biochemist who is known for his research about the insulin molecule which led to his conclusions that all proteins have definite and unique sequence of chemical compositions. He also developed the Sanger Method for DNA sequencing which later utilized in the DNA mapping for the Human Genome Project. Sanger’s works landed him two Nobel Prize in Chemistry.

Max Planck was a German theoretical physicist who is known for his theory of energy called energy quanta or also known as quantum theory. It played an important role in some of the significant scientific discoveries during the 20th century.  Max Planck won a Nobel Prize in 1918 for his astounding work.

13. Neils Bohr

Neils Bohr was a Danish physicist who won the Nobel Prize in Physics in 1922 for his amazing work about understanding the structure of atoms. He also developed the Bohr model of the atom where he said that the energy levels of electrons are discrete and that it revolves in stable orbits around the atomic nucleus.

14. Jonas Salk

Ivan Pavlov was a Russian psychologist who discovered “condition reflexes” which explains why our tummy might rumble when we hear the lunch bell ring or why a dog drools when it sees food. He explained that our body can be conditioned by our surroundings. Ivan Pavlov won the Nobel Prize for Physiology in 1904 which made him the first Russian Nobel laureate.
