New Process of making steel Henry Bessemer Do you like to take pictures in good lighting to get that GLOW? Well taking a picture with good light or simply looking for something in the dark with a source of light was possible with the help of Henry Bessemer. The steel he made is used in wires and we use wire for light so your glowing pictures wouldn't be possible without Henry Bessemer. We all love taking pictures for our Instagram and to have that amazing feed. Without light most of our pictures would be dim and boring.Am I right? Before Bessemer made steel we used cast iron and wrought iron. That material is way to heavy to make wires so that wouldn't help with our lighting issues.We used wrought iron sort of like a heavy substitute for
George Ohr was a mysterious and odd man. He was born in Bolixi, Mississippi July 12, 1857. His origins are from German. Meaning his parents were German immigrants who came to the United States. George Ohr was interested in various many other trades before finally learning about ceramics. He then became interested. He was an educated clay maker learning in New Orleans from a man named Joseph Meyer (“Wikipedia Contributors, George E. Ohr”).
Long ago in the year, 1863, on a many acred farm, there lived a man by the name, Augustus McCallister. McCallister was a wealthy,scoldful and greedy man who inherited land formerly owned by his father in which flourished with many crops and income. How could a single man run such an abundance of land, you may ask? The land was ran by slaves who day by day, harvested crops with gloveless hands which were torn and battered by the thorns of the brush. Who walked on dried,rough and tilled ground with shoeless feet. Who worked in the heat of the day without an ounce of water or a shirt on their back. McCallister would whip the men till they were blue in the face, if the commands he gave at the beginning of the day were not met. He would beat the women till they no longer recognizable for simply making a dish that he did not fancy. The children were cursed at and scolded for playing instead of working. He was a very cruel man and he enjoyed every second of it.
Lou Wegner is a teen activist who helps save animals when their abandoned or in danger. When Lou was 14, he volunteered at Baldwin Park Animal Shelter.He quickly discover that animals were euthanized to make room for the continuous flow of animal coming in.These animals were famIly pets crying as their owners walked away. According to Meet the Teen Animal Activist Who Took Two Shelter Dogs to Prom it said, “When actor Lou Wegner was 14, he found out what really happens to unwanted pets at shelters. While volunteering at Baldwin Park A“It was heartbreaking. All these dogs crying in their cages. Knowing they would be put down broke my heart,” Wegner
He worked with George Westinghouse and Nikola Tesla during the late 19th century so bring electric lighting into houses and offices. Incandescent lighting is when light is produced by heat. Around 1870s, there was already lighting called arc lighting. Those were placed in large indoor rooms such as a stage and outdoors in streetlight lamps. Arc light was proven to be impractical in housing or offices. During the 1879, Edison did research in an entire electrical systems which would deal with a generator, a distribution system, and a light bulb. His main focus though was the light bulb. It needed to be strong enough so that the heat wouldn 't cause the light bulb to explode. He worked with carbon filaments which burned inside a glass globe as electricity flowed through the filaments. During the same year, Edison worked with Francis Upton to make a generator that produced direct current, which is also what Edison is very well known for. Direct current was used for incandescent
George best was an athlete that played soccer for Manchester United and Northern Ireland national team. Best was suffering from alcoholism throughout his whole life which lead to many issues including his death. Around 1984 best was given a 3 month sentence to prison for getting caught drunk driving and for also assaulting a police officer. Later in best life he was diagnosed with severe liver damage around 2000. In 2001 George was taken to the hospital and then found out he had pneumonia. In London of August 2002 George best had a liver transplant in kings college hospital. Due to best liver transplant there were controversy because of him being an alcoholic. He was found drinking and driving once again which lead to a 20 month banned. later in 2002 he was taken to the hospital due to a kidney infection because of the immunosuppressive drugs that were use to prevent his body from rejecting his transplanted liver. In 2005 best was dead due to lung infection and multiple organ failure.
iron” and finally to “alloy and electricity”. The work is also intensely concerned with the relationship between war and technology. Though the book was written in 1934, its
In life, you have thousands of choices to make each and every day. When victory occurs is at times when you will be passionate and love what you do.If you love something, you will benefit power in your heart which then will make your succeed at what you want to do. There was a time when not a single person in the world thought it was physically possible to run under a four minute mile. One man proved the world wrong, Roger Bannister was the first person to run under that 4 minute mile mark. After Roger ran that four minute mile, over 20,000 people followed in his footsteps the achieve that amazing feat. If you know that someone has obtained something, there is no reason why you can’t do it too. Every choice you make will impact your life.
Hiram Maxim, founder of the U.S. Electric Light Co., at Bridgeport, CN, and the inventor of the Maxim machine gun, hired Lewis Latimer as an assistant manager and draftsman. Latimer's talent for drafting and his creative genius led him to invent a method of making carbon filaments for the Maxim electric incandescent lamp. In 1881, he supervised the installation of the electric lights in New York, Philadelphia, Montreal, and London.
The light bulb is the way we see in the dark, the way we find our way, the way we know when to go at a stoplight. How did Thomas Edison achieve this invention? Knowledge. Knowledge of electricity and the needs of those around him. In The Great Gatsby, Daisy Buchanan claims that she wants her daughter to be “a beautiful little fool.” In other words Daisy is saying that ignorance is bliss. Some others believe that knowledge is power. The advancement from candles to light bulbs changed the culture entirely. People could easily do the work they needed to after sunset, and it even led to more inventions. We need knowledge to advance, and for this reason powerful knowledge is more valid than blissful ignorance.
Imagine living in a world without electricity? You would basically be living in complete darkness. What would you do? Today I am going to be talking about an invention during the Industrial Revolution that changed the world and made it a little more brighter. Well this is all thanks to America’s leading businessman, Thomas Edison, who invented the first ever electric light bulb. Many of you may know who he is and what he invented. Well his invention helped illuminate whole cities and it changed lives during the Industrial Revolution because it had many great outcomes. It helped the pace of the city life quicken because now factories would be able to operate after dark. By the 1890s, cables carried electrical power from dynamos to factories.
Edmund Spenser was a well-known poet during the 1500s, who greatly influenced the way poetry was written. There is not a lot to know about Spenser’s childhood life, but many people have heard of him because of his unique writing style. During the 1500s many poems were written in Petrarchan or Shakespearean sonnet form, but Spenser chose a different form to use. Spenser used a very creative style known as the Spenserian sonnet; Spenser’s poems were based on romance since his wife, Elizabeth Boyle, was his inspiration.
Carbon fibers were discovered in the late 1800s by Thomas Edison. The early lightbulbs Edison created used the carbon fibers as filaments. These carbon fibers used to create the early lightbulbs had a substantial tolerance to heat, but they lacked the tensile strength of modern carbon fibers. Edison used cellulose-based materials, such as cotton or bamboo, to make his carbon fibers. He used a method called “pyrolysis” to cook the bamboo at high temperatures in a controlled atmosphere to carbonize bamboo filaments, making them fire-resistant and capable of enduring intense heat needed for luminescence.
While working on the lightbulb, his biggest obstacle was creating the right filament. In all, he tried over three thousand materials trying to find the perfect one. A year and a half later, Thomas found the answer. He found out that a sewing thread covered in carbon, then baked at a certain temperature was the answer. By that time, Thomas was thirty years
During the middle ages welding was very common. Early Egyptians learned the art of welding. Several of their tools were made by welding. A set of specialized workmen called blacksmiths created tools by melting the metal, then hammering them together. This method did not change much until the dawn of the 19th century which held major breakthroughs in welding. An open flame (acetylene) was very important to the history of welding. It allowed manufactures to make metal tools and equipment. In 1836 a man named Edmund Davy discovered acetylene which was soon utilized in the welding industries. Coated metal electrodes were first introduced in the 1900s. A coating of lime covered the electrode and made the weld much more stable. A number of other welding processes were also invented, such as seam welding, spot welding, flash butt welding, and projection welding. Stick welding also became popular around this time too. In the 1920s automatic welding was first introduced by P.O. Nobel. Automatic welding integrated the use of arc voltage and bare wire. It was mainly used for fixing old, molding metals. Several types of electrodes were also developed during this decade. A new type of welding was developed in the 1940s by Meredith. This became known as Heliarc Welding. Gas shielded arc welding or GTAW was another significant milestone in the welding history. Several advancements in the welding field were made in the 1960s. Dual shield, inner shield, and electro slag were some of the more important kinds developed. Plasma arc was also invented and was mainly used for metal spraying. Even now more techniques are being made. For example, laser welding was developed by the Russians and is being used more and more every day (“Welcome to
Thomas Alva Edison is a very well-known American inventor. He invented about 1093 devices that influenced us greatly, such as light bulb, microphone, telephone receiver, universal stock ticker, phonograph, kinetoscope (used to view moving pictures), storage battery, electric pen, and mimeograph. Edison also improved many other existing devices as well. In the period from 1878 to 1880, Thomas Edison began serious research into developing a practical incandescent lamp. Edison and his associates worked on at least three thousand different theories to develop an efficient incandescent lamp. In 1878, Edison built his first high resistance incandescent electric light. Incandescent lamps make light by using electricity to heat a thin strip of material (called a filament) until it gets hot enough to glow. Many inventors had tried to perfect incandescent lamps to "sub-divide" electric light or make it smaller and weaker than it was in the existing arc lamps, which were too bright to be used for small spaces such as the rooms of a house.Edison's lamp would consist of a filament ho...
