Scientific History

Charles Augustin de Coulomb
(1736-1806)

Charles Augustin de Coulomb was a French physicist that was born on June 14th, 1736 in Angouleme, French. Coulomb was a pioneer in electricity theory. Coulomb worked as a military technician for France in West Indies. When the French revolution happened, he retired from his job and lived in Blois, France. There he continued his research in the field of magnetism, friction, and electricity. 

In 1777 he found a torsion balance to measure magnetic force and electric force.With his discovery, Coulomb made research about the force produced by two electrically charged bodies. From the result of his research, he succeeded in finding out that the electric force between two electrically charged bodies was directly proportional to the product of their charges and inversely proportional to the square of distance between those two bodies. That statement is known as Coulomb's law.
In 1779 Coulomb published the treatise Theorie des machines simples (Theory os Simple Machine) that analysed friction in a machine. On August 23rd, 1806 Coulomb died. His name was immortalized as the unit of electric charge, that is Coulomb (C).

the nature of life in a particular habitat is determined to a large extent by the nonliving, or abiotic, part of the environment, that is, the environment's physical and chemical features such as salinity or bottom type. each environment makes different demands, and the organisms that live there must adapt to those demands. individual organisms can adapt to their environments to some extent through changes in their behavior, metabolism, pattern of growth, and other characteristics.

Solving Problems in Mathematics

About Solving Problems Now we've seen a problem and worked out a solution, however rough, let's look at the whole business of problem solving. There is no way that at the first reading i can expect you to grasp all the infinite subtleties of the following discussion. So read it a couple of times and move on. But do come back to it from time to time. Hopefully you'll make more sense of it all as time goes on. Holton's Analysis of solving problems a. First take one problem . Problem solving differs in only one or two respects to mathematical research. The difference is simply that most problems are precisely stated and there is a definite answer (which is known to someone else at the outset). All the steps in between problem and solution are common to both problem solving and research. The extra skill of a research mathematician is learning to pose problems precisely. Of course he/she has more mathematical techniques to hand too. b. Read and understand . It is often nec...
