Eighteenth Century Ballooning
In a time where the skies are full of aircraft, it is hard to
imagine a time when air travel was nothing but a dream. That was
just the case during the early eighteenth century. The dream of flight
was so concentrated on winged flight that ballooning was actually and
accidental discovery. The shift to alternate opportunities to fly
occurred in 1766 with the discovery of hydrogen. Henry Cavendish
discovered the gas he coined the “inflammable gas.” At that time this
meant that the gas was highly combustible, unlike today’s
interpretation of inflammable. What made this gas so important was
the fact that the gas was much lighter than the atmosphere. The
lighter gas would give the balloon lift in the surrounding atmosphere,
hopefully taking a human along with it. The new discovery brought a
lot of excitement to the pursuit of air travel. The discovery began to
move forward in 1774 with Joseph Priestly’s publication of
“Experiments and Observations with Different Types of Air.” This
paper explored uses of the gas and further explained its properties for
future experimentation. In 1777, the paper was translated into
French and read by Joseph Montgolfier. The paper inspired
Montgolfier to further explore the possibilities of the gas. Montgolfier
and his brother Etienne began experimenting with the gas in hopes of
coming up with a device to give them flight. This became a reality in
1786 when the two brothers were able to fly small cloth and paper hot
air filled balloons. This was the small and modest beginning to hot air
balloon flight.
The brothers had some complication to work out with the first
flights being experimental. They used dense smoke from burning
chopped wool or damp straw to lift the balloon. The smoke idea most
likely came from a concept left over from the medieval times. They
believed that smoke had more of a virtue of lightness, and lighter
meant that the balloon had a better chance of flight. Another
possibility is that the brothers believed that the dense smoke would
simply be better contained in the balloon. Some individuals even
believe that the brothers used thick smoke to conceal their ideas.
The Airplane was first invented in 1903; it amazed everyone but never really took off because of how dangerous it still was. They used planes in WWI but they threw them aside. After WWI (around mid 1920’s) the Federal Government had the idea of airmail. This was readily accepted; instead of receiving mail in two weeks it would only take a couple of days. Soon after this, transporting people quickly caught on although only the upper-class people could afford it, it soon became accessible to almost everyone. (Inventions: Airplane)
Over 60 years ago, airships were the "queens of the skies." In the early 1900s, a stubborn, yet brilliant German count, Count Ferdinand von Zeppelin, took keen interest in balloon flights and was devoted to the design and construction of airships. At first, he had many difficulties and setbacks but soon his airships were able to accommodate passengers as well. This lighter-than-air vehicle will later be known as a zeppelin.
Eisenmenger Syndrome (ES) is a heart defect that was first giving the name in 1897 (Fukushima, 2015). This syndrome happens when the birth defect is not treated before the lungs’ arteries become damaged. Eisenmenger Syndrome is named after Victor Eisenmenger a man who had a patient who showed symptoms such as, breathing complications and skin that was turning a bluish color. The autopsy of this patient lead him to discover a ventricular septal defect [VSD] (El-Chami, 2014), that causes a hole in the wall on the right and left ventricular. This is the defect that begins when signaling for pulmonary artery hypertension, which progresses into more advanced stages of ES. This birth defect eventually causes patients to have various
During the 1870’s the United States experienced great changes with the end of the Civil War. America was going through a period called Reconstruction. Tensions were fairly high and an air of freedom was present throughout the nation. By 1877, it was obvious the United States was beginning to develop into a recognizably modern economic system of making, earning, spending, and living (Brown 60). In 1880, “over half of American workers worked on farms and only one in twenty worked on manufacturing” (Brown 59). Farmers outnumbered factory by a large number, but factories were still abundant. Child labor occurred after the Civil War as well. By 1872, more than 10,000 children were employed in Philadelphia’s industrial workplaces. That number was even larger in cities such as New York, and it increased as the years progressed (Brown 60).
Technological innovations were at its peak during the Gilded Age. Great minds such as Andrew Carnegie, Thomas Edison, and Nikola Tesla developed these technological advances. These innovations would nevertheless have a great impact in our country and would change the way we live. Processes such as the Bessemer Process, the creation of the light bulb, and safe electricity would be the technological innovations that would carry us into the 20th century, and put us as a country ahead of everybody else.
The decade from 1880-1890 was an interesting time for America, giving rise to great advancement in architecture, inventions and businesses. For instance, such now famous companies as Sears Roebuck Company, DeBeers and Johnson & Johnson opened in this time (Timeline). Also, the Brooklyn Bridge, the largest suspension bridge in the world was set up in 1883 (Museum). This decade saw another milestone for architecture, the skyscraper. The first skyscraper, built in Chicago out of an all-iron frame, was completed in 1885.
Type 2: Is the most common form of diabetes affecting 90-95% of the 21 million people with diabetes and is more common in African Americans, Latinos, Native Americans, and Asian Americans. Those people who are at higher risk of getting this type of diab...
During the Gilded Age, technological innovations were very abundant and very impressive. Technological innovations changed the lives of the American people during the Gilded Age, most changes being positive, and few negative. The Gilded Age also brought forth many skilled businessmen that ran company's that distributed these technological innovations. These innovations changed the lives of the wealthy businessmen, as well as the lives of the poor factory workers.
The ministries of Jesus and the Holy Spirit are closely related, each one serving an individual purpose while complimenting the other. Although the Father, the Son, and the Holy Spirit are all one in the trinity, they each have different roles that they play. The Holy Spirit plays an active part in our lives, as does Jesus. The role of the Spirit changed with Jesus. When Jesus died and rose from the cross, He opened up a new doorway for us, a new opportunity for us to experience the Holy Spirit. The Spirit became active and real to us in a way that He never could before. Today, our lives are focused on Jesus, focused on His love and sacrifice. His present ministry is seen through His believers. We are His lights in this present dark world.
Throughout the first half of the 19th century, and especially after the War of 1812, America has taken on yet another revolution. In this time period, the country saw a rapid expansion in territory and economics, as well as the extension of democratic politics; the spread of evangelical revivalism; the rise of the nation’s first labor and reform movements; the growth of cities and industrial ways of life; a rise in abolitionism and reduction in the power of slavery; and radical shifts in the roles and status of women.
Diabetes mellitus also known simply as diabetes refers to a group of metabolic diseases which affect the body’s homeostatic mechanism used for maintaining and regulating the body’s blood sugar levels. Diabetes is a chronic condition which, in 2013 was estimated to be affecting 382 million people worldwide.[1] People suffering from diabetes are required to constantly be vigilant of their blood sugar levels to ensure it does not go below or above optimum levels. Depending on the type of diabetes and glucose level range, they may need to inject themselves with insulin or eat high sugar foods to restabilise their body. Failure to do so can lead to other long term health effects.[2]
The 1920’s are also known as the "Roaring 20’s". It was the first modern decade experienced by this country, as America flourished after WW I. The average number of hours worked per week dropped from 60 hours to 48 hours (Rayburn). For the first time, people felt that it was just as important to play as it was to work; family outings and weekend trips had become things that workers expected (Rayburn). Women became more open by appearing in public smoking and drinking. Trojan condoms first appeared and sex became an open issue for discussion.
What do you think of when you hear and or say “gunpowder”? Well, you might say to make bullets heat or burst, but did you know it was a mistake when the chinese discovered it. “Gunpowder” was used to trade for different kinds of supplies. There has been numerous items,inventions, and ideas that have been traded along The Silk Road that affect our life today such as gunpowder,paper,and the compass. Gunpowder has several low explosive powders in it and the main powder is gunsand. Gunsand is used for when the guns bullet shoots out it’s to give it an extra boost.
Lady Macbeth invokes evil spirits asking them to grant her extreme cruelty and to feel no remorse or pity for her victims. She asks the evil spirits to grant her these ills so she can take over Macbeth’s prophecy to prevent him from backing out, “Yet do I fear thy nature;/ It is too full o’ th’ milk of human kindness/ To catch the nearest way.” (1.5 16-18). Lady Macbeth uses the word milk to personify Macbeth’s weak nurturing nature. She believes that Macbeth is full of ambition and desire, but she also believes he is too reserved to attack when given a golden opportunity. She does not want to wait and let the prophecy unfold rather she wants to take control of it. Whe...
There are three types of diabetes. They are called Type 1 Diabetes, Type 2 Diabetes, and Gestational Diabetes. For the most part Type 1 Diabetes is usually caused by genetics or a severe childhood illness that has damaged the cells in the immune system. Type 1 diabetes is often called “juvenile diabetes“ and is commonly found in children. On the other hand Type 2 diabetes is often found in adults. There are many factors that cause Type 2 diabetes. A few of those factors are obesity and poor lifestyle decisions such as no exercise and overea...
