10 physicist and their contribution in the field of science?
Which scientist offered proof that atoms exist?
The existence of atoms was proposed by the ancient Greek philosopher Democritus in the 5th century BCE. However, John Dalton provided experimental evidence for the existence of atoms in the early 19th century through his atomic theory, which explained chemical reactions in terms of the combination of atoms.
What did Louis Pasteur do to save the wine industry?
He showed that wine could be 'pasteurised' to prevent its spoiling. This is a process involving careful heating and cooling which kills micro-organisms without destroying the quality of the wine.
Name the scientist who discover tv?
The scientist credited with inventing the first electronic television system is Vladimir Zworykin.
Did Louis Pasteur draw painting?
Louis Pasteur was a scientist, not a painter. He is best known for his contributions to microbiology and his development of the process of pasteurization to kill bacteria in food and beverages.
How did Louis Pasteur work helped to prevent diseases caused by micro-organisms?
Known as the founder of microbiology, Pasteur discovered the role of bacteria in fermentation. His experiments with bacteria conclusively disproved the theory of spontaneous generation and led to the theory that infection is caused by germs. Extrapolating from this knowledge, Pasteur then developed a process in which liquids such as milk were heated to kill all bacteria and moulds already present within them. This process became known as pasteurisation.
Recognising that infectious diseases are caused by microorganisms, Pasteur's research soon led others to investigate sterilisation, disinfection, vaccines, and eventually antibiotics. Pasteur created and tested vaccines for diphtheria, cholera, yellow fever, plague, rabies, anthrax, and tuberculosis. (source: today.wmit.net - 27 December)
Where does the name Koch come from?
The name Koch is of German origin and refers to someone who lived near a prominent oak tree or oak forest. It is a common surname in Germany and also occurs in other countries with German-speaking populations.
How does a Bohr diagram look like?
A Bohr diagram is a simple representation of an atom, showing the nucleus in the center with electrons in specific energy levels or shells surrounding it. Each shell is labeled with the number of electrons it can hold, and electrons are represented by dots or other symbols on the shells.
Why does Nikola Tesla invention matter?
As early as 1891 Tesla described the universe as a kinetic system filled with energy which could be harnessed at any location and that by year, Nikola Tesla had invented many useful devices. He set the stardarts for the current we use today, the basics of radio waves and wireless technology.
How did Nikola Tesla discovered the Tesla coil?
The Tesla coil was not a discovery. It was the work based in Tesla's mind and unleashed in the Colorado Springs laboratory. An earlier test, lasting only one second, had confirmed that the equipment in the building, an enormous "tesla coil" and the tower seemed to work. Now would come the full test.
When Tesla was ready, he shouted to his assistant, Czito, "Now! Close the switch!" Czito had been instructed to keep the machine running until Tesla told him to turn it off. Inside the building the massive switch was thrown and outside fireworks started to take place.
A heavy current raced through the primary coil of the machine and lightning bolts started to explode from the mast. Tesla watched as giant electrical sparks 135-feet long jumped from the large copper ball. They generated a thunder that could be heard 15 miles away. Tesla was so enthralled with the display that he lost all track of time.
Suddenly the lightning stopped. Teslas snapped out of his trance and raced into the building yelling, "Why did you do that? I did not tell you to open the switch. Close it again quickly!"
His assistant shook his head. He hadn't turned off the current. The power company was no longer sending it.
A quick call to the power station revealed the trouble. In the one minute it had been operating, Tesla's machine had overloaded the powerhouse generator, setting it on fire. The town of Colorado Springs was in a blackout and Tesla himself would have to take a team of trained workmen to the station to fix the dynamo. Even so, Tesla knew his new invention, his "resonate transformer," really worked.
Francesco Redi was an Italian physician and biologist who conducted experiments to disprove spontaneous generation. Louis Pasteur was a French chemist and microbiologist known for his discoveries in the principles of vaccination, microbial fermentation, and pasteurization, laying the foundation for modern microbiology.
What is the magic number for acceleration due to gravity?
It varies depending on your latitude with the equator having a slightly higher acc. due to gravity than the north/south pole . 9.8 m/s^2 is the average for the earth
Which Indian scientist discovered that plants respond to external stimulus?
Indian scientist Sir Jagadish Chandra Bose conducted pioneering research that demonstrated that plants respond to external stimuli. He observed and recorded plant responses to various stimuli such as light, sound, and touch, laying the foundation for the field of plant physiology.
Which scientist built the first electric motor?
William Sturgeon, a British scientist, is credited with creating the first practical electric motor in 1828. His design used a coil of wire around a horseshoe-shaped magnet and is considered the precursor to modern electric motors.
Who was the famous scientists in the 1900s?
Some famous scientists in the 1900s include Albert Einstein, Marie Curie, and Niels Bohr. Einstein is known for his theory of relativity, Curie for her work on radioactivity, and Bohr for his contributions to quantum theory.
Who is the scientist who used a prism to study light?
Sir Isaac Newton is the scientist who used a prism to study light. He discovered that white light is composed of a spectrum of colors when passed through a prism, leading to his development of the theory of color.
Which famous scientist had No as there elements?
Alfred Nobel, the inventor of dynamite and founder of the Nobel Prizes, did not have any elements named after him.
Did Nikola Tesla ever invent the light bulb?
No, Thomas Edison is credited with inventing the modern light bulb, not Nikola Tesla. However, Tesla did work on improving lighting technologies and was instrumental in the development of alternating current (AC) electrical systems that made the widespread use of light bulbs possible.
What invention supported Louis Pasteur's research?
Louis pasteur reject abiogenesis theory and give biogenesis theory which state that life exist from pre existing life. He prove it by one of his famous experiment of S shape funnel broth experiment
Which instruments would best help the scientist determine the results of his study?
Instruments such as spectrophotometers, microscopes, chromatographs, and centrifuges could help the scientist determine the results of their study by measuring chemical concentrations, viewing samples at a microscopic level, separating compounds for analysis, and isolating specific components within a sample.
What did Louis Pasteur's work show?
Louis Pasteur conducted a number of ground breaking experiments throughout his life. One was the disproving of the notion of spontaneous generation. Prior to this, there was the assumption that some life could spontaneously arise from nothing- such as the idea that maggots could appear from nowhere in a piece of rotten meat. In his experiment, Pasteur showed that while a piece of rotten meat attracted maggots, a piece of meat covered with a mesh just small enough to prevent flies from landing did not- indicating that flies had to deposit eggs for maggots to form. Also he developed the sterilization technique of pasteurization and invented a rabies vaccine.
How old is Madame Marie Curie?
Marie Skłodowska Curie was 66 years old when she died on July 4, 1934 (born November 7, 1867).
Why did Nikola Tesla go crazy at the end of his life?
There are various theories surrounding Nikola Tesla's mental health decline towards the end of his life. Some suggest it was due to financial struggles, lack of recognition for his work, or the impact of his experimental work on his mental well-being. However, it is challenging to pinpoint a single cause for his mental deterioration.
