Faraday also discovered the electromagnetic waves when conducting an experiment that later on led to the invention of the electric motor. James Clark Maxwell worked with Faraday in his later year of life. Maxwell later on proved Faradays idea for electromagnetism. Maxwell on demonstrated light was a wave of electric and magnetic fields. Maxwell also discovered the speed of light and found out it is impossible to catch up with it.
Electric charge, which can be positive or negative, occurs in discrete natural units and is neither created nor destroyed. Electric force – Is the attraction or repulsion of particles or objects because of their electric charge it is one of the basic physical forces. Magnetic force – Is the attraction or repulsion that arises between electrically charged particles because of their motion; the basic force responsible for the action of electric motors and the attraction of magnets for iron.

He claimed that the brain itself was the most important organ for secretion of this electric fluid, and the nerves were responsible for conducting this fluid to muscles and tissues. * The brain and the nerves do generate electric impulses that cause muscles to contract under a physiological state (that is, when the animal is alive). However, these electric impulses are much smaller than ones produced by the contact of two metals and are not present when an animal is killed. Alessandro Volta was a physics professor who made many contributions to the knowledge of electricity. * He invented the electrophorus, a device used to generate static electricity.
His name was Nikola Tesla. Tesla, originally from Serbia, immigrated to the US with no wealth or property. All that Tesla had was his imagination and many great ideas for electricity. After Tesla arrived in the United States, he was hired on as an engineer for Thomas Edison. Edison paid little mind to Tesla and viewed him as little more than another employee.

What are the identities of the substances found after electrolysis and heating? The identities of the substances found were Iodine, Iodide ion (I-), Triodide ion(I3-), Zinc metal and Zinc ion(Zn2+) Post Lab questions: 1. What did this experiment convincingly show about the composition of the white solid? I put that the experiment showed us the white substance was comprised of Zinc ions and iodide ions, and that the two ions and be separated back into their respective elements 2. During the electrolysis, a gray solid formed on the negative wire of the battery and the dark red solution formed at the positive wire of the batter.
With him inventing the one of the first telescopes, he could see multiple areas of space never seen before such as Jupiter. The most exceptional of these observations was Venus’ celestial pattern, which was explained by its revolution around the sun. Galileo’s views contradicted that of the Catholic Church and he was immediately put on trial after a letter he wrote to Duchess of Tuscany was discovered.4 Most of Catholic scientific doctrine came from pagan Greek philosophy. Examples of these were Aristotelian physics: the idea that there were only four elements fire, earth, air, and water.4 These ideas were later
The stone played an important role in the development of human life from ancient times. The stone is omnipresent and it is never given much importance. It has its role in technology, science and politics. (Hass,2008) Hass gives the example of a hammer in order to give an example of the use of stones in technology. Hass says that the stone-age hammer is now begin changes to steel hammer but the idea and the purpose remain the same .Hass(2208) support this key point of science by saying that “stone have taught us the shift in magnetic poles, and where to look for oil and metals”(p.57).Hass gives the use of the stone in politics; war, in metallurgy and in modern technology.
I visited the Griffith Observatory on Sunday November 16, 2014. During my visit I was able to observe the Tesla Coil demonstration developed by the late Nikola Tesla. Mr. Tesla designed the coil to someday transport electricity by air wirelessly and free. The energy would come from the magnetic field and atmosphere producing high-voltage, low-current, and high frequency alternating-current electricity. He had some success in his research but investors found it impractical and refused to support further research.
If the quantum dots are placed in the cavity, the spot on the wafers where there are no crystals, in the middle, and capture electrons then the aims of the process are a success. (Hennessey Interview) Kevin explains that you want to then put the process material into devices. This control of powerful light in this small cavity is what causes much speculation. The new devices which use this method are called quantum effect devices. According to Kevin, lasers and lights could be replaced with this technology.
