The Application of Science to Engineering
Improvements in engineering are very important to the industrialization and prosperity of a country. Although engineering improvements sometimes come through trial and error they are most often achieved by applying pure science and mathematics to engineering. Canadian engineering was improved a great deal in this manner. The engineering associated with building materials and long distance communication, two of Canada's most important industries, was improved through the application of pure science.
One of the most important scientific discoveries of all time was the law of electromagnetic induction discovered by an englishman, Micheal Faraday, in
1831. This discovery was applied to mechanical generation of electricity which made tremendous improvements to communications throughout Canada. The electric telegraph, first discovered in 1837 by Samuel Morse, was a great improvement over the mechanical telegraph which required the use of a telescope and was much less effective. It encodes messages electrically, transmits them over facilities such as copper wire, coaxial cable, and fibre optics to their destination where they are decoded into their original form. Combinations of long and short bursts of electric current are sent through a circuit thereby encoding each letter of the alphabet. More efficient transmission facilities were developed as the mining industry developed. The discovery of electricity sped up the development of mining through electric lighting and better machinery and ventilation, which led to better materials for wires and cables. Telegraph lines were set up along the CPR in 1885 as a convenient root, but also to relay information about the position of each train along the track to avoid collisions.
The telegraph was also the main source of information for newspapers.
Like the telegraph, the telephone wouldn't have been possible without the discovery of electricity. The telephone was discovered by Alexander Graham
Bell in 1876 and is much more advanced than the telegraph. It encodes variations in sound waves into variations of electric waves through vibrations of a diaphragm which are then transmitted. Electromagnets are used to send these vibrations through a cable, which are received on the other end by another diaphragm. For it's first few years the telephone was for public use only ( for calling fire stations, doctors…). A central exchange system was then set up and wealthy people began to gain access. The telephone quickly became essential in unifying and further developing the country.
In the construction industry there were several huge advances in the technology of building materials. Two related materials with similar methods of production are cement and bricks. Cement production in Canada began in 1889 in
Hull, Quebec. Portland cement was the principle type and consisted of lime,

For Americans, this allowed for overnight travel and became time-saving. Beneficial to businesses in the railroad industry, the demand of these cars went up. Moreover, Alexander Graham Bell was an inventor who created the telephone in 1876, inspired by the hearing impairment of both his mother and wife. The patent of this invention was soon recognized globally, and affected the means of communication. Although it was a novelty item, it was crucial and necessary for businesses to possess.
Only businessmen would have them due to traveling for work. Cell phones were referred to as “the lug phone” because of how big and bulky they were to carry with them. Nobody wanted or had the need for a cellphone when first brought into the market. Rosen then proclaims, “This changed in the 1990s, when cell phones became cheaper, smaller, and more readily available” (Rosen 2004). Cell phones were were becoming common around the world in different countries made by different companies. In some countries, the phones were still at a high price making them more elite and made for the wealthy class. The names for cell phones changed to “handy” and “portable” making people interested in buying the
I'll be talking about the science and technology and how it has changed over the years and how it has changed in different societies. The science and technology can only thrive in a situation where individuals are free to explore and think. The technology has changed so much just in the past fifty or ten years, from not having computers or Internet. The technology now is way more progressed than it just was ten years ago. We can take a car and we have made them safer by making them different chapels and structures. We have added air bags that protect you from hitting your head and being injured badly or even death. They have also changed the cars so they are just all
The cylinder phonograph proved to be successful, but the problem with the machine was that the tin foil only allowed a few uses. With the help of another great inventor, new advances could be made to improve this invention. The inventor of the telephone, Alexander Graham Bell, had set up a laboratory for his cousin, Chichester Bell and Charles Tainter. Bell a...
Learning is a continuous process and the day that you stop learning is the day that you start decreasing your rewards and lower levels of satisfaction. My ardent desire to acquire knowledge has motivated me to pursue higher studies at graduate level, and to take up a career in research in industry. I have taken this decision after carefully considering my academic background, profound interest in research and strong aptitude for problem solving.
Within living memory, young women who have wanted to study engineering faced such dissent that in 1955, Penn State’s dean of engineering declared, “Women are NOT for engineering,” asserting that all but a few “unusual women” lacked the “basic capabilities” necessary to succeed in this profession (Bix par. 2). Although the number of women in social sciences and humanities has grown steadily, women remain underrepresented in science and engineering. Bureau of Labor Statistics states that “women remain underrepresented in engineering constituting only 10 percent of full-time employed engineers and 7.7 percent of engineering managers...” Although this is the case, social norms, culture and attitudes play a significant role in undermining the role of women in the aforementioned fields in addition to the gendered persistence and their individual confidence in their ability to fulfill engineering roles.
On June 21, 1890, Bell and his assistant Charles Sumner invented a wireless telephone, named a photo phone. This photo phone allowed the transmission of both sound and huma...
Telephone lines and radio signals allowed individuals to communicate across the world. Alexander Gram Bell was the first to invent the telephone. While coming to the US to become a teacher for the death he thought of the idea of “electronic speech”. “This led him to invent the microphone and later the "electrical speech machine" his name for the first telephone,” stated www.pbs.org. Many contributed to the invention to the electric phone with the idea of the acoustic string phone, known as the lover’s phone. The tin can telephone had two tin cans tied together to with a string and wire. People today make this as a joke to talk to one another and kids also make the tin can phones as a toy. This illustrates that social media has always been around and even though it is a joke to today’s society this is how people used to have social interactions with one another before the Internet took
Despite the short amount of time since the introduction of the smartphone, the rapid development of the software and technology has had a tremendous effect on the everyday life of society today. The concept of communicating through a telephone was developed in the 1870s. Devices to transmit speech electrically were designed by Elisha Gray and Alexander Graham Bell, but Bell's design was patented first. On March 10, 1876, Alexander Graham Bell achieved one of his greatest successes in the making of the telephone. This brought upon a major change in communication and gave leeway to the improvement of the telephone in the days to come (Bellis, 2013b).
Engineer dates back to 1325 when an engine’er, someone who operates an engine, was referred to by a conductor as an engineer. (Ford)
Science and technology in the middle ages flourished because of the need of inventions to make life easier. In Europe, from the 5th century to the 16th century there was a radical change in the inventions made. It was between the fall of the Western Roman empire and the early modern era. This was a time for exploration in new ideas and ways of doing things. Europe invented many things for wars, time-keeping, and for everyday use. These inventions may be still used today. They range from huge mortar to a small set of eyeglasses. Europeans found that life was easier with new better inventions to help them in everything. There are a series of inventions about war because of nearby wars with neighboring civilizations or even within Europe.
Science and Technology has been around from the beginning of time. It evolved from the everyday efforts of people trying to improve their way of life. Throughout history, humankind has developed and utilized tools, machines, and techniques without understanding how or why they worked or comprehending their physical or chemical composition. Before we go any further a definition has to be given for both Science and Technology because they are both different in their own right even though the two are almost indistinguishable. According to the Oxford Dictionary Technology can be defined as the knowledge or use of the mechanical arts and applied sciences, while Science can be defined as the branch of knowledge involving systematized observation and experiment. Science can be further divided into three separate categories; Pure, Applied and Natural Sciences. In addition technology is often defined as applied science, it is simply the application of scientific knowledge to achieve a specific human purpose, however, historical evidence suggests technology is a product of science.
Science is a method of understanding how things work. It is important because we need science in order for things to work and to develop new technology that is used in every day life. It is personally important to me because I really want to become a vet when I get older and I would need to do really well in science. Even though science isn’t exactly my best subject, I am willing to put in the hard work and determination so I may eventually get better and learn what I need to know.
Mechanical engineering is a type of engineering which applies principles of physics and material science for the purpose of analyzing, designing, manufacturing and maintaining of mechanical systems (Gorp, 2005). It is involved with the production and usage of mechanical power in the operation of various machines and tools. Mechanical engineering is considered to be the most diverse engineering and has its breadth derived from the need to design tools and manufacture products which range from small individual parts to large systems. Mechanical engineering, as thought of by scholars, is related to Aerospace engineering, Manufacturing and Mechanical engineering (Van et al, 2011).
