“ Worst. Idea. Ever.” of chapter 1 is telling us what we hear on the radio, watch on the TV, see on the newspaper is not really true. Some time we need to look deep inside and think deeper into it to find out the fact. As many a human believe that Edison is the one who invents the light bulb, but in the chapter 1 states “Humphrey Davy invented it forty-five years before Edison was even born”. I believe every one after reading this chapter will be surprise just like me. And we may be asking:…

The Spirit Phone After the carnage of World War I, spiritualism was undergoing a revival, and many people hoped science could provide a means to contact lost loved ones. Edison himself was not a believer and admitted he had no idea if a spirit world even existed. Edison corresponded with British inventor Sir William Crookes, who claimed to have captured images on "spirit photographs." Edison was intrigued. Edison took the idea of the telephone and the telegraph a bit further and announced in…

What kind of car does an electrician drive? A Volkswagen (LaffGaff). To be an Electrician all you need is high school diploma, also electricians work in people's homes, on construction sites, in factories, and in electrical utility stations (Career Cruising). They may be required to bend or squat for long periods, in order to work on hard-to-reach wiring. There is always the threat of electrical shocks, but as long as proper safety procedures are followed, the number of accidents will remain…

Electroencephalogram (EEG) used to measure abnormalities in the brain which related to electrical activity (Fig.1). This measurement tracks and records brain wave patterns by using electrodes are placed on the scalp, and then signals go to a computer to record the results. Abnormal patterns in EEG indicate seizures and other problems [3][6]. The importance reason for using EEG is to diagnose and show seizure disorders. Also EEGs help to help to identify causes of other problems like sleep…

Nikola Tesla, (1856-1945) was the inventor of the World’s lighting and well-known for his contribution to the world of science and technology. Tesla, a son of priest from Orthodox faith, he was born in born in Serbian in the territory of Yugoslav. He is the first inventor of the outstanding radio communication. Tesla is also known for his invention, who devised the powerful alternating current (AC) model that significantly became the industry electric standard. AC is widely considered one of the…

Conceived on February 11, 1847, in Milan, Ohio, Thomas Edison ascended from humble beginnings to fill in as an innovator of significant innovation. Setting up a lab in Menlo Park, a portion of the items he created incorporated the transmit, phonograph, the primary monetarily handy brilliant electric light, soluble capacity batteries and Kinetograph (a camera for films). He kicked the bucket on October 18, 1931, in West Orange, New Jersey. At age 12, Edison embarked to give a lot of that…

Nikola Tesla was born on July 10, 1856 and later died January 7, 1943. He was born and raised in the Austrian Empire. Tesla received an advanced education in engineering and physics in the 1870s and gained practical experience in the early 1880s working in telephony. He emigrated to the United States in 1884, where he would become a naturalized citizen. He also work in new york city before he went on his own at the Edison Machine Works. In the wake of learning at the Realschule, Karlstadt (later…

composed of a positive electrode, a negative electrode, and an electrolyte solution. A permeable membrane, called a separator, plays an important role between the positive and negative electrodes; the separation is what allows the battery to create electricity. These cars are great for high school students or college students who only need to get around their community. When you only need to go short distances these cars help you to save money. Through the composition of the electric cars and…

Field strength or intensity is the force which maintains the magnetic flux and produces a particular value of the flux density B at that point in a magnetic field. Therefore the flux density is the cause while the flux density (B) is the effect. The flux density can be assumed proportionally to the field intensity in a magnetic field which comes in three parts. First part is: Where U stands for the permeability of force (the measure of the degree to which the magnetic line of force can…

Alexander Graham Bell was significant to the world because he created a faster and more efficient way of communication by inventing the telephone. Bell’s father, grandfather, and brother has all been associated with work on speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work. At the age of twenty three, Alexander Graham Bell moved to Canada with his parents. His research on hearing and speech at Boston University further led him to experiences with…
