What revolves the world, what makes the world work or light up. Language, Language is what powers up the world, just like a light bulb, that powers up your home. Both James Baldwin, author of If Black English isn't a Language, Then Tell me what Is? Then adding to my list is Sherman Alexie author of Superman and Me. They both emphasize that language could allow or disembowel any person in our twisted world. With their point of views are different from each other, about how they were raised and…

A sensor is a device that receives a stimulus, meaurand, or any input signal such as from heat, pressure, light, motion and many more, and responds with an electrical signal. This electrical signal then will decide what will be the result of an output. Depending on the input of the stimulus, the sensor will react to it in a particular way. Sensors are attached to an electrical device and they scan the surrounding environment. Then it converts the input signals to a voltage, current or charge.…

Thomas Edison a famous American inventor, who invented many life influential devices and one of the first inventors who used mass production stated the following quote. “To invent something takes 1% inspiration, and 99% perspiration.” I agree that to make a goal or an idea reality it takes a lot of hard work. Thomas Edison invented many life changing devices e.g. electric light, sound recording, and motion pictures. My reasons why I agree to the quote Thomas Edison stated is the following.…

Technology has significantly advanced for the past few decades, with abundance of inventions created by brilliant minds have filled the current world. One such brilliant inventor that made his name known in the inventing world back in the 1870s was Scottish-born American inventor Alexander Graham Bell, the founding father of the device that could transmit speech electrically; the telephone (Gray, 2011). The telephone was notably fashioned from his attempts to improve an invention that was…

Humanity is a collective group of thinkers, scattered across time and space, and, as such, no invention can be attributed to a single person, rather several people who continue to make innovations and improvements upon the design. It may then be argued that inventions aren't created, but grown through the ages until it is perfected. Such is the case with Thomas Newcomen, who, through improvements upon the design made by Thomas Savery, led to one of the major catalysts of the Industrial…

3.3.3 Selection of Die Angles The split die was designed for the ease of assembly for fabrication. AISI 52100 steel was selected as the material for the die fabrication. The entry part of the die is 12 mm and has 120 mm length. The profile of the die is also shown in the solid works software. The angle of the die is 90 is maintained, the slope radius is 20 mm. the Figure.3.1 & Figure. 3.2. illustrate the split die design and solid works model of the split die. Figure. 3.1 : Split die…

Andrew Hallidie set up his first wire rope making company in the gold fields of American Bar in 1856. Hallidie had learned his craft in Scotland where at the age of ten he had apprenticed under his father, Andrew Smith, who had a number of patents for the making of wire rope. At American Bar a quartz mill had built an incline railway using hemp rope to haul empty cars up and full cars down. The hemp rope required replacement every 75 days, Hallidie’s lasted for two years. Returning to San…

Wheatstone bridge is a device used to measure unknown resistance by passing current through the resistor [1]. Wheatstone bridge is made up of a power source and galvanometer that joins the two-parallel circuits which contains two resistors each. It is very useful in finding small resistances and is used in various applications such as strain gages. The following figure shows the arrangement of a Wheatstone bridge. Figure 1: Arrangement of a Wheatstone Bridge [1] Importance of Wheatstone…

What would you do if you were one of the smartest humans on earth in the 19th century? Could you invent things that defined modern era as we know it? What if I told you about a man who was one of the smartest and did made a significant change in the world history. Shouldn’t you know about him? Well, I think you should. Nikola Tesla was a Serbian American inventor born in 1856 in a small village in Serbia during the Austrian regime. In 1884 Tesla emigrated into the United States to work for…

During the late 1800’s, a significantly large amount of inventors, engineers and futurists emerged. Nikola Tesla was born on July 10, 1856 in Smiljan, Croatia. His passion for electrical engineer was instigated by his mother, Djuka Mandic, who built him numerous gadgets while he was growing up. While Tesla has attending the University of Prague in Graz, Austria, he became acquainted with the Gramme dynamo, which was used as an add-on generator in manufacturing and farming machinery. Tesla took…
