In the 1890’s scientist found that invisible rays are emitted when matter is hit with a jolt of electricity. Such experiments involved transmitting electric arcs between two ends of cathode ray tubes. Some physicists discovered some substances that spontaneously emitted invisible rays regardless of electricity or any other type of …

The name LASER is an acronym for Light Amplification by the Stimulated Emission of Radiation. In 1917, Albert Einstein first theorized about the process which makes lasers possible called “Stimulated Emission.” In this paper, we can view the impact of the lasers technology on society from four perspectives: the strength, …

Michael Faraday was the discoverer of the relationship between electricity and magnetism, and that one could not exist without the other. Through his studies he came to believe that there was no such thing as the ether, and he did not believe that matter was a physical substance. Rather, he …

Exams – a word that many students dread to hear, a word that seems to have the magical power to transform a happy and cheerful person into a frustrated and nervous wreck. What are exams, and should they be done away with entirely? Examinations, exams for short, are longer and …

During World War II women were exposed to many different experiences that they didn’t expect, formerly thought to be men’s duties. This changed their outlook on life and also made themselves and other people realise that they could confidently take on the roles of men; that their part was not …

Aim: The enthalpy change of combustion of a fuel is a measure of the energy transferred when one mole of fuel burns completely. A value for the enthalpy change can be obtained by using the burning fuel to heat water and using fact that 4.2j of energy are required to …
