name five scientists and their achievements
Answers
Answer:
1. Sir Isaac Newton (1642–1726) Newton was a polymath who made investigations into a whole range of subjects including mathematics, optics, physics, and astronomy. In his Principia Mathematica, published in 1687, he laid the foundations for classical mechanics, explaining the law of gravity and the laws of motion.
2. Louis Pasteur (1822–1895) Pasteur contributed greatly towards the advancement of medical sciences developing cures for rabies, anthrax and other infectious diseases. Also invented the process of pasteurisation to make milk safer to drink. He probably saved more lives than any other person.
3. Galileo3. Galileo (1564–1642) Creating one of the first modern telescopes, Galileo revolutionised our understanding of the world, successfully proving the Earth revolves around the Sun and not the other way around. His work Two New Sciences laid the groundwork for the science of Kinetics and strength of materials.
4. Marie Curie (1867–1934) Polish physicist and chemist. Discovered radiation and helped to apply it in the field of X-ray. She won the Nobel Prize in both Chemistry and Physics.
5. Albert Einstein (1879–1955) Revolutionised modern physics with his general theory of relativity. He won the Nobel Prize in Physics (1921) for his discovery of the Photoelectric effect, which formed the basis of Quantum Theory.
Answer:
Archimedes
Archimedes is the best known mathematician and scientist from ancient times. In addition to brilliant discoveries in mathematics and physics, he was also an inventor.
Robert Hooke
Robert Hooke discovered plant cells and discovered Hooke’s Law – the law of elasticity. He also:
invented the balance spring, vital for accurate timekeeping in pocket watches
invented a machine that cut teeth for cogs used in watches – these cogs were cut in finer detail than any person could have managed, enabling more delicate watch mechanisms to be developed.
Benjamin Franklin
Benjamin Franklin discovered one of the fundamental laws of physics – the Law of Conservation of Electric Charge – and proved that lightning is electricity. He also:
invented bifocal spectacles
invented the Franklin stove
invented the lightning rod
Louis Pasteur
Pasteur invented the process of pasteurization and patented it in 1862.
Louis Pasteur discovered that some molecules have mirror images – these can be described as left-handed and right-handed versions of a chemical compound.
C. V. Raman
Physicist who won Nobel Prize in 1930 for his Raman Effect........
