A scientist is someone who discovers the nature of the universe. The investigator, on the other hand, is someone who tries to create useful devices and products. A few have succeeded in both endeavors. Below is a list of 17 famous scientists and their discoveries.
Albert Einstein
The photon, also known as light quantum, is a tiny energy packet of electromagnetic radiation. This idea originated from Albert Einstein's explanation of the photoelectric effect, where he proposed the existence of isolated energy packets during the transmission of light. Albert Einstein was best known for his general and special theory of relativity and the concept of mass-energy equivalents (E = mc 2.).
JJ Thomson
The English physicist and Nobel laureate in physics JJ Thomson was credited with the discovery of the electron and was honored, it was the first subatomic particle to be discovered. Thomson was able to show that cathode rays were made up of unknown negatively charged particles (electrons), which he calculated and hypothesized that there could be a body smaller than an atom and that there were sufficient proportions. He is also credited with finding the first evidence for the existence of isotopes for stable elements.
Ernest Rutherford, an Australian chemist considered the "father of nuclear physics". He was the first to suggest that an atom has a small charged nucleus surrounded by space and that it is provided by small electrons which later became known as the Rutherford model. He was credited with discovering protons and assuming the existence of neutrons.
John Dalton
- John Dalton's main contribution was his theory of the atom, which consists of the following five parts:
- Atoms are made up of tiny particles known as atoms
- Atoms are indivisible and indestructible
- The atoms of the given material are identical in size, mass, and chemical properties
- In a chemical reaction, atoms are separated and reassembled
- Dalton made many discoveries based on his observations.
James Chadwick
The British physicist James Chadwick was awarded the Nobel Prize in 1935 for his discovery of the neutron. Neutron-induced bombings can cause nuclear fission and splitting to produce large amounts of energy. Thus, Chadwick's discoveries were important for the discovery of nuclear fission and ultimately the development of the atomic bomb.
The discoveries of Isaac Newton created a launchpad for the future advancement of science. His most notable inventions are:
Newton's three laws of motion laid the foundations of modern classical mechanics.
The celestial body has given us the ability to predict the movement of gravitational forces.
The discovery of calculus has given us a powerful mathematical tool to aid in the precise analytical treatment of the physical world.
Isaac Newton
Isaac Newton is one of the greatest mathematicians and physicists of all time, and his inventions and discoveries further fueled the spread of human thought.
Charles-Augustin de Coulomb
Charles-Augustine de Coulomb is now best known as Coulomb's law, which explains electronic attraction and repulsion. He made this law to study the law of electrostatic repulsion laid before the English scientist Joseph Priestley. He also worked extensively on the friction of instruments, the elasticity of metallic and silk fibers. The SI unit of electrical charge - Coulomb is named after him.
Georg Simon Ohm
The German physicist Georg Simon Ohm invented the law after his name, known as the "Ohm's law", which states that the current conductor is directly proportional to its voltage and inversely proportional to its resistance.
Michael Faraday
Faraday was a man dedicated to discovery through experimentation. He was famous for not abandoning ideas that came from scientific intuition. When he thinks of an idea, he will continue to experiment with multiple failures until he meets the expected expectations. Below is a list of some of his notable discoveries:
- Discovery of electronic magnetic induction
- The discovery of benzene
- Faraday's Electronic Analysis Act
- Gas liquefaction and refrigeration
- Michael Faraday is a respected scientist of all time.
Thomas Edison
Thomas Edison made many original discoveries and discoveries. Here, we've listed a few notable things:
- Invented the carbon rheostat
- Discovery of incandescent light
- Motion the picture camera invented
- Invented the fluorescent electric lamp
- Discovered thermionic emissions
Edison has been described as "America's greatest inventor." He developed many devices in such fields as mass communication and electric power generation. He worked with many researchers and staff, pioneering the application of organized science and teamwork principles in the discovery process.
Henri Becquerel
Henry Becquerel was a French physicist, best known for his work on radioactivity for which he received the Nobel Prize. As a result, Beckerel's SI unit of radioactivity has been named after him.
Max Planck
Mary Sklodowska-Curie was a chemist who conducted pioneering research on radioactivity. She is the first woman to win the Nobel Prize. He is best known for his discovery of polonium and radium.
Max Planck
Max Planck, a German physicist, is best known for his proposing the power of quantum theory, for which he was awarded the Nobel Prize. His work makes significant contributions to nuclear and subatomic processes.
Heinrich Rudolf Hertz
During his work on electromagnetism, Heinrich reported another important phenomenon known as the photoelectric effect. He noticed that UV rays lost metal charges faster than otherwise, enabling him to publish his findings in the journal Annalen der Physic. He did not further investigate this effect. Later, in 1905, Albert Einstein proposed that light-photons in various energy packets were known as photons. This discovery led to the development of quantum mechanics.
