What happened before Einstein changed how scientists thought about the universe?
From the time of Aristotle people had thought it impossible for electromagnetic waves, including light, to travel through 'empty' space. They theorised the presence of a substance known as aether (or ether) as a medium, and in the years prior to Einstein's publication about special relativity several scientists wrestled with the difficulties inherent in making use of this concept. Please see the link for more of the history.
Where do scientists get their lab rats to experiment on?
A scientist who regularly tests on rats will usually breed their own as rats breed very easily and have many babies in one litter. This also helps them to reduce the risk of the rat having an underlying disease or illness.
Samuel Langley (1834-1906) wasa renowned American astrophysicist and astronomer.
Why do you think scientists use models to study the movements of earth and it's moon?
to tellif its day or night
What tools do scientist use to learn about tornadoes?
One tool is mobile Doppler radar, which uses microwave beans to study deatures within a thunderstorm or tornado. In a few cases scientists have managed to deploy probes inside of tornadoes to take measurements. This has met with limited success, though, as such attempts are difficult and dangerous.
Some scientists have simulated tornadoes in supercomputers to try to model the dynamis of a tornado.
Why did Alexander Fleming move on to other work?
Alexander Fleming moved on to other work after his discovery of penicillin because he wanted to focus on researching other aspects of microbiology and bacteria. He felt that others could continue the development of penicillin while he pursued other scientific interests.
What scientists believe in evolution?
The overwhelming majority of scientists across various fields, including biology, paleontology, and genetics, accept the theory of evolution as the best explanation for the diversity of life on Earth. The theory of evolution is supported by a wide range of evidence, including the fossil record, comparative anatomy, and molecular biology. While there may be scientists who do not accept evolution, they represent a very small minority within the scientific community.
How does a forensic scientist use colorimeter?
A forensic scientist can use a colorimeter to measure and analyze the color of samples collected from crime scenes. This can help in identifying unknown substances, detecting bloodstains, and comparing different samples for consistency or differences. Colorimeters provide objective data that can be useful in criminal investigations and court proceedings.
Why do scientist share details of their work with other scientist?
So they can ask the other scientists for their opinion and help.
Niels Bohr proposed this model in 1913. His model of the atom suggested that electrons occupy specific energy levels and emit or absorb energy in quanta when they move between these levels, corresponding to the sharp lines observed in the emission spectra of elements.
Why is the internet useful to the scientists?
The world wide web was invented by scientists at CERN to distribute data around the world for analysis. Something it still does. It also allows fast communication and instant access to scientific journals.
How do you think the society in which scientists live might influence their views?
Darwinian Theories
Why did some scientists oppose development of the hydrogen bomb?
Some scientists opposed the development of the hydrogen bomb due to the potential for catastrophic consequences if it were used in war, such as massive destruction and loss of life. They believed that the focus should be on promoting peace and disarmament rather than escalating the arms race. Additionally, there were concerns about the morality and ethical implications of creating such a powerful and destructive weapon.
What impact did Rene Descartes have on the Renaissance?
he was a great leader and he was an amazing at math and science
When scientists gain new information they often revise What?
New information can lead to revised theories.
What aided scientists in deciphering Egyptian hieroglyphics during the 19th century?
the Rosetta Stone
How do scientists use the word theory?
Theories are based on observations and testing. They are widely held to be accurate and form the basis for scientific principles. Theories are upheld by mounting and corroborative evidence. In contrast, a hypothesis is a possible explanation based upon initial observations and an understanding of supporting facts. As observations and tests further support a hypothesis, it becomes accepted within the scientific community and begins to form a theory..
What could be a reason why a scientist might reject a peer review for publication?
if he is smarter than his peers. Albert Einstein would be an example
How do scientists replicate the work of other scientists?
Research results are published in scientific journals. If some scientist wishes to replicate the work of another scientist, he or she reads about it in the published report, and then does what the written description says.
What radiation emitting from stars to earth?
All forms of electro-magnetic ... the full spectrum from UV to visible light to infrared.
Pulsars emit x-rays
