Canada’s Economics and Science Technology by Kristina Canada’s Economics Canada’s economy creates resources, it uses land, it provides the country with money, goods and services and it employs citizens. All these factors help to define Canada’s identity. About one hundred years ago Canada was identified as a country of farmers, fishers, hunters and loggers.

“His job on the train caused Edison to become deaf. One morning, he tried to climb the first step but was not able to keep his balance. A railroad worker grabbed him by the ears and hauled him up. Edison felt something snap inside his head, which started his deafness, and got worse throughout his life,” (Thomas Alva Edison). Edison’s deafness allowed him to focus on his work and not be distracted by outside noises and people. He was able to focus on his own thoughts and not hear the others who…

The Morse Code was invented by Samuel Morse in 1836. It was developed and worked on between 1830s and 1840s. The Morse code is a method of sending messages, that consist of sounds by telegraphs and radio operators. These messages are send through a wire or radio. This system is made up of a series of dashes, dots, short signals, long signals and spaces. These different signs all represent letters, numbers, punctuation marks and other types of symbols.

Invention of the Telegraph The telegraph is one of the inventions that started long distance communication. To begin with, Samuel Morse came up with the marvelous idea of this invention. However, he did have a competitor by the name of Charles Wheatstone. The original telegraph was developed in the 1830s. It was tested and updated through a number of years from when it was invented. It’s actually quite impressive how this whole system was developed. According to ‘Morse Code and the Telegraph’…

In 1959, metal–oxide–semiconductor field-effect transistor (MOSFET) was invented by Dawon Kahng and Martin M. (John) Atalla at Bell Labs. Julius Edgar Lilienfeld had already patented the basic principle of this kind of transistor in 1925. But later the Bell Labs edition was allocated the name bipolar junction transistor, or merely junction transistor, and design of Lilienfeld came to be identified as field effect transistor. Later, Jean Hoerni found that Silicon dioxide (SiO2) should be used to…

Imagine waking up at sunrise and tucking in your bed at sunset. Then, after many years, while striking stones, you discover fire, something that would help you stay awake at night in presence of light. Burning firewood and lighting up oil lamps remained sources of light until the Nineteenth century when the Incandescent light bulb was co-invented by two scientists - Thomas Edison and Joseph Swan. Since then, the lightbulb has been the invention of the 19th century that has shined on us for…

AT&T started in 1875 when Alexander Graham Bell invented the first talking telegraph. In 1876 and 1877 Bell got his patents on his telegraph. New Haven, CT was where the first telephone exchange existed in 1878 and this was operated under Bell Telephone. It took about three years for more telephone exchanges to open in most major cites in the United States. It was decided then to build a long distance telephone network and it started in New York and in 30 years is reached all the way to San…

of various frequencies and then back to a tone that sounds like the original voice. The first telephone was inveted by Alexander Graham Bel. Alexander brought together the world’s first telephone, using parts frome a shop of electrical equipment and the skill of his assistant Thomas Watson. In 1876, at the age of 29 Alexander created the telephone and in one year he formed the Bell Telephone Company. I think the advantages of this invention are great especially at the time the telephone came…
