In cases where things are on such a huge scale that it becomes hard for scientists to study, it's important for a scientist to construct a model. Scientists create models to learn about complex phenomenon and to simulate real conditions. For example, it may be easier to study global warming on a small model than studying it across the entire earth.
Was it not Neils Bohr. http://en.wikipedia.org/wiki/Niels_Bohr#Atomic_research
The scientist who discovered the electron shell in 1913 was Niels Bohr. He proposed the Bohr model of the atom, which described electrons orbiting the nucleus in distinct energy levels or shells. This model helped explain the stability and spectral properties of atoms.
The scientist who developed the atomic theory of matter was John Dalton. He proposed that matter is made up of indivisible particles called atoms that combine in specific ratios to form different compounds.
Linus Pauling is the scientist who devised the scale of numerical values reflecting the tendency of an atom to attract electrons, known as electronegativity. It is a useful tool in predicting chemical bonding behavior and understanding the nature of chemical reactions.
The Australian scientist, M Vella came up with this model in the late 1900's.

scientific model is a testable idea based on studies on a particular subject. It is useful to scientist for further studies and research on similar idea, subject.
very useful
A scientist might use a model as a research method for a few reasons. This model could tell the scientist how something moves for example.
When the scientist is trying to represent an object or a system.
They are very useful to scientists because it helps them see stars and planets better
It creates a representation of something difficult to see.
What type of model a model is usefulcuz it shows a replica of a product
The model T was one of the most useful inventions of all time. They were used for everything by everyone
Descartes was a mathematician and a philosopher, not a scientist. Of course, his work in mathematics has been very useful to science.
