Give seven named scientist
Answers
Answer:
Explanation:
1.Luis Alvarez
Luis Alvarez
Lived 1911 – 1988.
Luis Alvarez was a Nobel Prize winning physicist, probably most famous for the discovery of the iridium layer and his theory that the mass extinction of dinosaurs was caused by an asteroid or comet colliding with Earth. Besides doing the normal work you might expect of a physics professor, Alvarez took on more unusual projects, like making use of cosmic rays to search for hidden chambers in an Egyptian pyramid.
Early Life and Education
Luis Walter Alvarez was born on June 13, 1911, in San Francisco, California. His father, Walter Clement Alvarez, was a doctor and author who wrote a large number of medical books. His mother was Harriet Smyth.
Luis began his education in San Francisco, first at Madison School, then at San Francisco Polytechnic High School. In 1926, when he was 15, his father changed jobs and the family moved to Rochester, Minnesota. Luis graduated from Rochester High School, then started a Bachelor of Science course at the University of Chicago in 1928, intending to major in chemistry.
After a couple of years, his grades in chemistry were not as good as he had hoped – he was scoring Bs. Also, he had also grown much more interested in physics, so he decided to major in physics instead. He graduated with a B.S. in physics in 1932, then continued as a graduate student at Chicago, where he was awarded a master’s degree in 1934, and a Ph.D. in physics in 1936.
Even at the beginning of his time as a graduate student, Luis Alvarez was at the cutting-edge of physics. His doctoral advisor was Arthur Compton, winner of the 1927 Nobel Prize in Physics for his discovery that electromagnetic radiation, such as visible light, has particle-like properties.
In 1932, Alvarez built an array of Geiger counters to study cosmic rays. In 1933, using the data he had gathered, he and Compton published a paper in the Physical Review establishing that cosmic rays are positively charged particles. Compton gave much of the credit for the work to his young graduate student.
After completing his Ph.D. in 1936, Alvarez returned to his home state, beginning work as an experimental physicist at the University of California’s Radiation Laboratory in Berkeley.
2.André Marie Ampère
Andre Marie Ampere
Lived 1775 – 1836.
André-Marie Ampère made the revolutionary discovery that a wire carrying electric current can attract or repel another wire next to it that’s also carrying electric current. The attraction is magnetic, but no magnets are necessary for the effect to be seen. He went on to formulate Ampere’s Law of electromagnetism and produced the best definition of electric current of his time.
Ampère also proposed the existence of a particle we now recognize as the electron, discovered the chemical element fluorine, and grouped elements by their properties over half a century before Dmitri Mendeleev produced his periodic table.
The SI unit of electric current, the ampere, is named in his honor.
