Why is it important to design experiment to test a problem in science?

Because experiments can prove your theories, and if you are not documentating the experiment properly, other scientists might think it's not valid.

Furthermore you are screwing up your theory if you don't make precise data collection, and calculation from your experiment, the theory won't be proved right.

What is the scientist who studies the atmosphere?

There are two distinct disciplines the study of gases. Aerostatics is the study of gases that are stationary or not moving. It studies density allocation. Aerodynamics is the study of gases that are in motion. People in this field study the motion of air and how it interacts with solid objects.

What material did Rutherford use in his famous experiment?

Rutherford's experimenters were Hans Geiger, and Ernest Marsden, both of whom went on to have worthwhile science careers. The metal foil used in the Rutherford experiments was gold, for this foil amy be made extremely thin by careful beating, whilst still being imperforate.

Which element has a full valence shell of electrons?

The elements with a full valence shell are the noble gases.

Metals wouldn't conduct electricity if their valence shells were full. They have very empty shells (1, 2 or 3 valence electrons), as opposed to insulators, which have relatively full ones (more than half full). As the previous poster said, full electron coverage equates to Helium, Argon, Neon, Krypton, Xenon and Radon - the noble gases. They are the ultimate insulators, and they don't react with any other element (hence the name, implying haughtiness).

There are structures called clathrate compounds in which noble gas atoms are surrounded by other atoms - but the gas atoms are effectively being held in a cage instead of bonding with the other atoms,

Why are most scientists male and white?

Opinions:

* boys rule * Its because science is sexist * In the past, science (math chemistry, etc.) was regarded as a male field of endeavor by males even though there were examples such as Marie Curie to disprove the stereotype. Even today teachers and guidance councellors often discourage girls from taking the Maths and Science stream of secondary schools subjects that would allow them to enter the science maths and engineering courses in university. To have famous examples you have to have agoodly number of female participants in these areas. Until now thy numbers have een low, but these numbers are increasing. Women have been scientists as long as men have been scientists. See http:www.astr.ua.edu/4000WS for a list of famous women of science. There were times in human history that women were encouraged to study technical subjects.

What is the name of a scientist who studies diamonds?

The name for a gem expert is a gemologist. They are experts in natural and artificial gems.

What element is named after Ernest Rutherford?

A. Ghiorso at the Lawrence Berkeley National Laboratory announced that, while they had been unable to confirm the Dubna group's results, they had identified at least two isotopes of element 104 different from the one identified by the Soviet scientists. They bombarded californium-249 atoms with carbon-12 and carbon-13 ions to creates isotopes with mass numbers 257 (half-life of 4.8 sec), 259 (half-life of 3 sec), and possibly 258 (half-life of 13 msec). Disputing the Soviet claim of discovery, the Americans suggested the name rutherfordium to honor the British physicist Lord Ernest Rutherford. An international committee set up to resolve such disputes decided in 1992 that the Berkeley and Dubna laboratories should share credit for the discovery. The syntheses of at least 10 isotopes of rutherfordium, with half-lives ranging from 0.5 msec (Rf-254) to 65 sec (Rf-261), have been confirmed.

Rutherfordium was first time obtained by Gheorghi Nikolaevici Flerov, Iuri Ţolakovici Ohanessian, Iuri V. Lobanov, V. I. Kuzneţov, V.A. Druin, V.P. Pereligin, K.A. Gavrilov, S.P. Tretiakova, V. M. Plotko in 1966 (Dubna, Russia), bombarding 242Pu with 22Ne.

A long controversy with an American team is mentioned, solved by IUPAC in 1997.

What did Georges Cuvier do?

Georges Cuvier, a French zoologist, made the first important discoveries involving fossils and was a major contributor to paleontology and comparative anatomy. One of his most major scientific contributions was applying his knowledge of anatomy to piece together fossils of extinct animals.

He also developed the theory of catastrophism, saying that many natural disasters occurred to cause great changes all over Earth and that Earth was only 6,000 years old.

What did bohr contribute to science?

Niels Bohr (the father, not the son who also got a Nobel prize) is known for:

- Nuclear models with layers explaining radiation

- Contributions to quantum mechanics

Where did Antonie van Leeuwenhoek live?

Antonie van Leeuwenhoek (October 24, 1632 -- August 26, 1723) was born in Delft, a city in the province of South Holland in the Netherlands. He also died in Delft. Except for the six years he spent in Amsterdam as an apprentice, he spent his entire life in Delft.

Why should scientists continue to study cells?

Yes.Scientist need to study about stem cells beacuse,they can discover so many way to be free from the dangerous diseasess.

Edited answer:

because we have yet to understand in detail, the mysteries of living matter

Who were the scientists that were responsible for creating the atom model?

the scientist behind the concept of the atom are joseph john thomson,goldstein, and james chadwick!

What evidence did scientists use to figure out Earths inner core is solid?

Scientists use the difference in density between the inner and outer core as evidence that the inner core is solid. This was proven using seismic waves traveling through the earth.

Who is the scientist that discovered a way of purifying milk?

Louis Pasteur is the father of pasteurisation. This is a method used in the dairy industry to produce fresh milk with a shelflife of +/- 7 - 14 days.

Pasteurisation involves heating a liquid to a set temperature for a set time. In most dairies these days a High Temperature, Short Time (HTST) pasteurisation process is used. This is 72°C for 15 seconds.

Through this process the spoilage organisms and pathogens that are in the milk are destroyed. This makes the milk safe for consumption and also increases the shelf life.

Was Michael Faraday a pioneer scientist?

No, Michael Faraday did not receive the Nobel Prize. In fact, he died in 1867 almost 30 years before it was created by Alfred Nobel in 1895. Faraday, who was a pioneer of electromagnetism and chemistry, did, however, receive the Royal Medal in 1867 for his contributions to science.

How did Niels Bohr's model of an atom differ from that of his predecessor Ernest Rutherford?

The orbital revolutionof the electron is not expected to be stable.Any particle in a circular orbit would undergo accleration.

During accleration,charged particles would radiate energy.Thus,revolving electrons would lose energy and finally fall into nucleus.If they were so,the atom would be highly unstable and hence matter would not exist in the form that we know.We know that atoms are quite stable.

What r the names of 5 caribbean scientists and what they discovered?

Edsel Edmunds- Nematologist

What are the limitations of scientist model about the earth layers?

Well it is much smaller than the actual earth. The crust is a little tiny tiny sliver compared to the other layers. It doesn't get to show the temperature or state of matter on a model (at least most).

Why do scientists use models and prototypes to test ideas?

To provide a better coverage for test cases effectively.......
