Why might a scientist use stimulation in a controlled experiment?
The reason they would is because it is a lot safer.
What was Albert Einstein famous for?
The special and general theory of relativity, E=mc2, reveals the equivalence of mass and energy. When Einstein applied his theory to gravitational fields, he derived the "curved space-time continuum" which depicts the dimensions of space and time as a 4-dimensional surface where massive objects create valleys and dips in the surface. This aspect of relativity explained the phenomena of light bending around the sun, predicted black holes as well as the background radiation left from the Big Bang. For his work on relativity, the photoelectric effect and black body radiation, Einstein received the Nobel Prize in 1921. Albert Einstein also worked on the atomic bomb project. He is also famous for creating this quote:
Insanity is expecting something different in doing the same thing over and over.
What are some of the ways scientists communicate with each other?
They communicate with each other by sharing their ideas and maybe talk about their experiments together or writing to each other
Do scientists base their explanations of the natural world on evidence or belief why?
They have evidence, but if they cant prove something, even with the evidence, it becomes a theroy, or belief. So sometimes it is based on evidence and fact, sometimes on belief.
Why do scientist not use water as a solvent for paint?
Scientists can use water as a solvent for paint, but only if the pigments of the pain are water soluble. If the pigments are not water soluble, then some other solvent must be used, for example oils. This is the difference between watercolor paintings and oil paintings.
How do you established the direction of force applied on the glass?
To establish the direction of force applied on glass, consider the desired outcome of the force application. Factors like the object's weight, friction with the surface, and the angle of contact all influence the direction of force. Additionally, understanding the structural integrity of the glass will help determine the most suitable direction to apply force without causing damage.
Why did Szilard call it a a black day in the history of mankind?
That quote refers to the success of the Manhattan Project.I think it is quite obvious - atomic bombs are extremely dangerous. A few hundred-thousand people have already been killed by them during World War II, during the so-called Cold War it seemed as if a large part of humanity would be wiped out, and on several occasions this almost happened, and it may still happen.
What is the step scientist and engineers use to approach a problem?
Engineers will often use reverse-engineering to solve problems. For example, by taking things apart to determine an issue, finding a solution and then putting the object back together again. Engineers know how things work, and so they constantly analyse things and discover how they work.
What is an example of a situation of a scientist being creative?
First, every scientist is creative when they think out of the box and know to consider abnormalities or the unexpected as useful information.
Madam Curie experimented with radium. She did hundreds of experiments, with negative results, until she was sick from radiation poisoning. However, she was intelligent enough to recognize that the sediment left over after evaporation in her experiment must have been radiium because the dish glowed in dark light. Otherwise, the dish in the daylight LOOKED like a failed experiment.
Alexander Fleming worked with molds for years. He left an experiment unfinished. When he returned, he noticed the mold did not grow on one area of the petri dish. This anomaly caught his attention, because it shouldn't have happened and hadn't happened before! He went on to discover penicillin which has now saved billions of lives since it was introduced in World War II.
Geo-spatial mapping uses satellite images of the earth to solve real world problems. Scientists use a map of the stars to orient the position of the satellite in space. Clever scientists figured out they could tell the satellite to look "behind" itself in the direction of stars sitting "behind" the earth. Thus, researchers got the first images of nearly perfect 3-D images of cities. That was creative thinking!
How can research done by one scientist be validated?
Using as few test subjects as possible
The scientist's own data
Television and magazine coverage
Peer review
Why do you think it is important forma scientists organize their data?
"we should organize data because it it would help us figure out our conclusion or answers in a more organized fashion. It would keep things neat and understandable ."
Why did scientist agree to use SI units worldwide instead of the units common at their locations?
Scientists must be able to reproduce the results of experiments done by others in order to verify each other's conclusions. Using the same units worldwide removes the potential for error in converting between units or confusion between units which have different values in different places (e.g.: English mile, Irish mile, French mile, etc.).
What are three sources of information scientists use when they do research?
observation
analyzation
experementation
scientists makes models so when they do the acual project they can see what to do from the scale size to the acual figure.
to do scale testing
scientists use models to help them understand what they are working on
How can a researcher be a scientist?
They can be, if their research is into a scientific subject and follows the scientific method.
Note, not all researchers are scientists.
What do scientist do when a hypothesis is not supported by an experiment?
Scientists then state another hypothesis and test it out with another experiment.
classification.
Scientists use their data to make charts and to communicate the results of an experiment?
scientists use their data to make charts and ____ to communicate the results of an experiment.
A peer Review
The five skills are touch, hearing, smelling, tasting, and sight.
