Who was well known for saying eureka?
This exclamation is most famously attributed to the ancient Greek scholar Archimedes. He reportedly proclaimed "Eureka!" when he stepped into a bath and noticed that the water level rose-he suddenly understood that the volume of water displaced must be equal to the volume of the part of his body he had submerged. (This relation is not what is known as Archimedes' principle-that deals with the upthrust experienced by a body immersed in a fluid[2][3]) He then realized that the volume of irregular objects could be measured with precision, a previously intractable problem. He is said to have been so eager to share his discovery that he leapt out of his bathtub and ran through the streets of Syracuse naked.
Archimedes' insight led to the solution of a problem posed by Hiero of Syracuse, on how to assess the purity of an irregular golden votive crown; he had given his goldsmith the pure gold to be used, and correctly suspected he had been cheated, by the goldsmith removing gold and adding the same weight of silver. Equipment for weighing objects already existed, and now that Archimedes could also measure volume, their ratio would give the object's density, an important indicator of purity.
This story first appeared in written form in Vitruvius's books of architecture, two centuries after it supposedly took place.[4] Some scholars have doubted the accuracy of this tale, saying among other things that the method would have required precise measurements that would have been difficult to make at the time.[5] For the problem posed to Archimedes, though, there is a simple method which requires no precision equipment: balance the crown against pure gold in air, and then submerge the scale with crown and gold in water to see if they still balance.[6]
What is volume would be occupied by 7.75g of a substance with a density of 1.70766?
The answer depends on the units for density. Commonly used ones are gram per cubic centimetre and kilogram per cubic metre. There is a difference of a factor of 1000 between the two.
Depending on which it is,
Volume = Mass/Density, with appropriate adjustment for units.
How scientist can prove that central blue cone is the blue flame is unburnt gas?
They could test it and see how i works?
Why do scientists gain new knowledge?
Scientists have two motives for gaining new knowledge. First, science is motivated by curiosity. Scientists are very interested in understanding the world better. Second, scientific knowledge has proved to have many practical applications, and our experience has been that new knowledge is going to come in handy in various ways that are often difficult to predict.
By keeping documents and writing things that is important and needs to keep track with.
What might a scientist do after observing and recording information in an investigation?
Create Conclusions And Theories
Why is it important for a scientist to make careful observations and to keep accurate records?
So They Can Have The Accurate Answers
How do scientists discuss new ideas?
Scientists usually publish their new ideas in a scientific journal. They can also hold a symposium to discuss the ideas, if they wish.

true
When a controlled experiment is not possible or practical, two types of scientific investigations are observation and modeling.
1. Its important because if you repeat you'll get consistent results.
2. That means if a scientist gets different results it means they did something wrong in the experiment
Why is it important for scientists to keep open mindedness and skepticism in harmony?
If scientists are closed minded, they will reject legitimate theories and discoveries just because they are new, and they conflict with previous theories. And when legitimate theories are rejected due to an excess of skepticism, science fails to advance. If, however, scientists are overly credulous, and do not apply an appropriate degree of skepticism to new claims, they will wind up wasting their time investigating an endless series of pseudo-scientific, crackpot theories, and they will never have time to make actual scientific progress. It is necessary to be able to reject nonsense rapidly, in order to avoid wasting time on it, while not being too hasty in rejecting theories which, when investigated, will prove to have a legitimate basis. So, it's a balancing act. One must avoid going to extremes, either of open mindedness or of skepticism. This is true not only for scientists, but for everyone.
Why is rejection of hypothesis helpful to scientists?
That is progress, you start with a hypothesis, e.g. the moon is made of cheese, then it is tested by experiments to see if it's right. If the experiment says it's wrong, that is something that does not have to be tested again.
How did the scientist change the way they worked as a result of the scientific revolution?
Hey, I've just received a free Minecraft Giftcodan one too! >> minecraftcodes.me <<
Which of the following is a reason why society might initially reject a new scientific theory?
The simple answer is people don't like change. And to have this new idea that goes against something that may have been believed for hundreds or thousands of years, will very likely be rejected at first.
What do scientists study to learn more about early humans?
Scientists study fossils, ancient tools, and DNA to learn more about early humans. By comparing and analyzing these sources of evidence, scientists can piece together information about the behavior, lifestyle, and relationships of our ancestors.
