Michael Faraday is a British physicist and chemist, best known for his discoveries of electromagnetic induction and of the laws of electrolysis. He was born in 1791 to a poor family in London, Michael Faraday was extremely curious, questioning everything. He felt an urgent need to know more. At age 13, he became an errand boy for a bookbinding shop in London. He read every book that he bound, and decided that one day he would write a book of his own. He became interested in the concept of energy, specifically force. Because of his early reading and experiments with the idea of force, he was able to make important discoveries in electricity later in life. He eventually became a chemist and physicist.
Faraday built two devices to produce what he called electromagnetic rotation: that is a continuous circular motion from the circular magnetic force around a wire. Ten years later, in 1831, he began his great series of experiments in which he discovered electromagnetic induction. These experiments form the basis of modern electromagnetic technology.
In 1831, using his "induction ring", Faraday made one of his greatest discoveries - electromagnetic induction: the "induction" or generation of electricity in a wire by means of the electromagnetic effect of a current in another wire. The induction ring was the first electric transformer. In a second series of experiments in September he discovered magneto-electric induction: the production of a steady electric current. To do this, Faraday attached two wires through a sliding contact to a copper disc. By rotating the disc between the poles of a horseshoe magnet he obtained a continuous direct current. This was the first generator. From his experiments came devices that led to the modern electric motor, generator and transformer.
Faraday continued his electrical experiments. In 1832, he proved that the electricity induced from a magnet, voltaic electricity produced by a battery, and static electricity was all the same. He also did significant work in electrochemistry, stating the First and Second Laws of Electrolysis. This laid the basis for electrochemistry, another great modern industry.
The research that established Faraday as the foremost experimental scientist of his day was, however, in the fields of electricity and magnetism. In 1821 he plotted the magnetic field around a conductor carrying an electric current; the existence of the magnetic field had first been observed by the Danish physicist Hans Christian Oersted in 1819.
Ewald Georg von Kleist is a German scientist who created the capacitor in November of 1745. Regrettably, Kleist did not have the proper paper work to claim in the records that the design of the capacitor was his idea. Many months later, a Dutch professor named Pieter van Musschenbroek created the Leyden jar, the world’s first capacitor (on record). It was a simple jar that was half filled with water and metal above it. A metal wire was connected to it and that wire released charges. Benjamin Franklin created his own version of the Leyden jar, the flat capacitor. This was the same experiment for the more part, but it had a flat piece of glass inside of the jar. Michael Faraday was the first scientist to apply this concept to transport electric power over a large distance. Faraday created the unit of measurement for a capacitor, called Farad.
God tells his children, “He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away” (Revelation). Death is one of the most frightening and confusing times a person can go through. Watching a loved one pass away is also one of the hardest trials a person can experience. Many people assume that death is a time of pain and the only thing that they can do is mourn and watch their loved one fade away from the earth. This is wrong. There are ways that people can turn a bad situation to good. Dying doesn’t have to be painful and full of suffering. The County Hospice staff makes sure of this. The Hospice staff not only takes care of passing patients physically, but they also take care of the patients emotionally and spiritually. Hospice staff also plays a key role in helping families during the grieving process.
Franklin worked on his first electrical experiment in 1747 and was immediately intrigued. He continued with his electrical experiments including electrifying his kite string in a storm. He also examined how the storms worked. Franklin learned about how "air ways" cause different weather and storms.
Tesla’s career as an inventor started when he was in his late twenties. He displayed his incredible understanding of electricity and physics when he created his first invention, the induction motor. The induction motor is a small, electric motor that has become a very useful machine. In fact, most household appliances run using Tesla’s induction motor (Vujovic 1). Score one for Tesla. Soon after he invented the induction motor, Tesla moved to America to try his luck at living the American dream. While in New York City, Tesla got the amazing opportunity to work for his hero, Thomas Edison. However, Tesla soon quit working for Edison due to some disagreements between the two inventors. And so with Edison and his men biting at Tesla’s heels, Nikola set out on his own to make a name for himself (Vujovic 1). Tesla soon became Edison’s greatest competitor. While tinkering in his lab with one of his inventions called the Tesla Coil, Tesla discovered that he could send and receive radio signals when his coils were tuned to the exact same frequency...
Benjamin Franklin is known for conducting lots of experiments dealing with electricity. His most famous being the kite experiment. He became fascinated with electricity when he was accidently shocked in 1746. Benjamin wondered if there was a way to protect buildings and the people inside of them from lightning. He thought that this could benefit people in the
Death is a universal truth. Hospice reduces the suffering associated with death. Hospice is considered the philosophy and model for quality, compassionate care to terminally ill patients. Patients accepted into a hospice program usually have a prognosis of less than six months to live (Potter, Perry, Stockert & Hall, 2017, p. 761). Hospice provides skilled medical care, pain management, emotional, and spiritual support tailored to the patient’s needs and wishes. The goal of hospice is to focus on the quality of life during the end of life. It gives patients a sense of dignity, provides patients and families with support, and it is cost effective. Today, seven out of ten Americans die from chronic disease. By 2020, the number of people living with a chronic illness will increase to 157 million (Hogan 2012). As the elderly population in the U.S. continues to increase, the importance of hospice will only continue to grow.
Hospice is giving dignity, support and love to end of life patients. Hospice works with the patient’s pain to give the patient comfort, not to hurry death or hasten the dying process, but to relieve symptoms that are sometimes associated with grief and dying. In my experience, I have witness the positive effects associated with comfort care for both patients and love ones. Dying patients grieve for various reasons. Sometimes it is mentally, physically, emotional or psychological and it affects their love ones as well as their level of comfort. Our promise to every patient we take care of is “To provide exceptional care, to guide the patient and their family on their journey, and to respect their choices. Their comfort, needs and wishes come first. They can count on us when and where they need us” (Hospice and Palliative Care, 2013).
We can see that the hospice concept is a bio-psychosocial approach to the dying process, concerned with biological, psychological, and social health. Because of its proponents, Hospice is considered a more humane and sensible approach to terminal illness, combining care, comfort, and support of family and friends as the individual faces death. Their concern for dignity and fo...
Grief is an acknowledgement that we loved someone, and the nature of our relationship with that person determines how we grieve. Grief is an exclusive process; one that is as different as the person experiencing it is. As Hospice volunteers we must respect each person’s individual grieving practices and refuse to give in to the temptation to advise others to follow our exact paths. Although those of us who have also experienced such loss can sympathize with other’s feelings, we must be attentive to the fact that they are mourning the loss of a relationship that was exclusively theirs. As Hospice volunteers, we must consider this exclusivity and abstain from persisting that the grieving person grieve any way other than what is best for them. Keeping that in mind, I have information that can help you understand the grieving processes at various stages in life. Through this understanding, you will be able to assist family members and loved ones, as well as your dying patient to achieve a more peaceful death.

Edison is most famous for the development of the first electric light bulb. Like I said Edison was born into a time where America wasn’t very developed. He was born, and electricity had not been developed. But thanks to Edison when he had passed away on October 18, 1931 whole cities were lit up in electricity. For electricity, much of the credit goes to Edison.
The history of engineering goes back into the 19th century when Alexander Volta (1745-1827) made a remarkable discover regarding the nature of electricity (Cosgrove 749). He discovered that electrical current could be controlled and could flow from one point to another. By the time the mid-19th century came about the rules for electricity were being established. During this time electromagnetic induction was discovered by Michael Faraday who lived from 1791 to 1867 (749). Also during this time Samuel Morris invented the telegraph in 1837 which relies on the principles of electromagnetic induction (749). Alexander Graham Bell, who lived from 1847 to 1922, created the telephone which also uses electricity in order to operate (749). Through the success of the telephone, Bell Telephone Company was established. In 1878, the light bulb was finally invented by Thomas Edison who lived from 1847 to 1931 (749). Off the principles of Faraday’s electric motor from 1821, Nicholas Tesla invented a more efficient and powerful electric motor in 1888 (749). To make these inventions be more significant, effort was expended to make better motors and transformers and to enhance the power needed to make them function. Through these inventions during the middle 19th century, it led to the capability of lighting homes and cities through the use of electricity, and it also led to the creation of the telephone communication system (750).
In 1750, Benjamin Franklin wanted to prove that lightning was caused by electricity. He tested his theory with an experiment in which he flew a kite with a metal key attached to it into a storm cloud. The historical facts are not clear as to if he actually carried out the experiment, which is why there is doubt that he is the discoverer of electricity. But, we still credit him with the idea. He also did other experiments concerning electricity, but others after him would have to ...
The phenomenon called electromagnetic induction was first noticed and investigated by Michael Faraday, in 1831. Electromagnetic induction is the production of an electromotive force (emf) in a conductor as a result of a changing magnetic field about the conductor and is a very important concept. Faraday discovered that, whenever the magnetic field about an electromagnet was made to grow and collapse by closing and opening the electric circuit of which it was a part, an electric current could be detected in a separate conductor nearby. Faraday also investigated the possibility that a current could be produced by a magnetic field being placed near a coiled wire. Just placing the magnet near the wire could not produce a current. Faraday discovered that a current could be produced in this situation only if the magnet had some velocity. The magnet could be moved in either a positive or negative direction but had to be in motion to produce any current in the wire. The current in the coil is called an induced current, because the current is brought about (or “induced”) by a changing magnetic field (Cutnell and Johnson 705). The induced current is sustained by an emf. Since a source of emf is always needed to produce a current, the coil itself behaves as if it were a source of emf. The emf is known as an induced emf. Thus, a changing magnetic field induces an emf in the coil, and the emf leads to an induced current (705). He also found that moving a conductor near a stationary permanent magnet caused a current to flow in the wire as long as it was moving as in the magnet and coiled wire set-up.
Nikola Tesla is regarded as one of the most brilliant inventors in history. His work provided the basis for the modern alternating current power system, as well as having developed both radio and the fluorescent light bulb. He worked with Thomas Edison and George Westinghouse, among others. He was also widely misunderstood by his peers and the public at large.
