Physics

so that the scientist will be easy to do his/her experiments=)

Analyze the experiment to decide whether the results were flawed.

Thomas Edison's greatest challenge was the development of a practical incandescent, electric light. Contrary to popular belief, he didn't "invent" the lightbulb, but rather he improved upon a 50-year-old idea. In 1879, using lower current electricity, a small carbonized filament, and an improved vacuum inside the globe, he was able to produce a reliable, long-lasting source of light. So he said. Tesla worked for Thomas Alva Edison for 1 year At that time, the most important "inventor" in the world was named Thomas Alva Edison-the so-called wizard of Menlo Park.... Edison was credited with the invention of the DC dynamo and the electric light bulb . . . but the only thing he really invented was the ELECTRIC CHAIR!!

Despite the fact that Tesla worked closely with Westinghouse, he still retained his own laboratory, and was very happy when he was working there. He continued to make new discoveries, one of which was a lamp that fluoresced, and was actually a forerunner of today's fluorescent tubes. These hit the market some fifty years after Tesla's prototypes! He also investigated many other phenomena including X-rays and a vacuum tube or valve very similar to the Audion or triode valve pioneered by de Forest in 1907.

people who specialise in that subject x

Francesco Paresce Marconi is Guglielmo Marconi's grandson and Degna Marconi's son!!!

Hope that helps!!!

Singer and Nicholson are scientists credited with proposing the fluid mosaic model of the cell membrane in 1972. This model describes the cell membrane as a dynamic structure composed of lipids and proteins that can move and interact within the membrane. Their model revolutionized our understanding of cell membrane structure and function.

His Serb father, Reverend Milutin Tesla, was a priest in the Orthodox Metropolitanate of Karlovci which gathered to Serbs of the "Greek-rite" as they were legally referred to in Austria-Hungary at the time. His mother, Djuka Mandic, from a prominent Serb family of the Banija, made home craft tools. He was one of five children, having one brother and three sisters. His godfather, Jovan Drenovac, was a Captain in the Krajina army.

As you can see, they were not poor but they were not rich.

Bill Nye. this is my first time being on here

If they can't do a controlled experiment chances are they're advanced and know what they're doing. Depending on the experiment itself, the scientist would have to come up with a procedure that doesn't involve a control. Although there may be no official control, they probably still compare the results to something.

Tesla arrived in the United States in 1884, at the age of 28, and by 1887 had filed for a series of patents that described everything necessary to generate electricity using alternating current, or AC.

Tesla made his income by selling his patents. By the age of 40 he was allready a millonary. In his last day he spend all his income and died pennyless at 86 years old.

of course a technologist

To make sure your results are Valid/reliable. You should always repeat your experiments and if using times or amounts and in the future going to make a graph its best to do the experiment 3 times and calculate the average on place the average result on to your graph.

Some scientists are people that explore the world and try to tell us about the planet but we don't understand!

In 1887, he constructed the initial brushless alternate-current induction motor. He demonstrated the brushless two-phase one-fifth horsepower (150 W) induction motor to the American Institute of Electrical Engineers (now IEEE) in 1888. Also in 1888, he developed the principles of his Tesla coil wich he patented it 1891.

In April 1887, Tesla began investigating what would later be called X-rays using his own devices as well as Crookes tubes. He did this by experimenting with high voltages and vacuum tubes. His technical publications indicate that he invented and developed a special single-electrode X-ray tube. Tesla's tubes differed from other X-ray tubes in that they had no target electrode.

At the 1893 World's Fair, the World Columbian Exposition, in Chicago, Illinois, celebrating the 400th anniversary of Christopher Columbus' first voyage to America, an international exposition was held, in which, for the first time, a building was devoted to electrical exhibits. It was a historic event and the beginning of a revolution as Tesla and Westinghouse introduced visitors to AC power by providing AC energy to illuminate the World Columbian Exposition. The public at large observed firsthand the qualities and abilities of AC power.

Some doubted that the system would generate enough electricity to power industry in Buffalo. Tesla was sure it would work, saying that Niagara Falls had the ability to power the entire eastern U.S. On November 16, 1896, the first transmission of electrical power between two cities was sent from Niagara Falls to industries in Buffalo from the first commercial two-phase power plants (known as hydroelectric generators) at the Edward Dean Adams Station. The hydroelectric generators were built by Westinghouse Electric Corporation from Tesla's AC system patent designs. Tesla's system designs alleviated the limitations of the previous DC methods. The nameplates on the generators bear Tesla's name. He also set the 60 hertz standard for North America. It took five years to complete the whole facility.

He was the genius that created:

Alternating-current power transmission

The Death Ray Machine

Fluorescent lights

Induction motor

Polyphase alternating-current system

Radio

Rotating magnetic field principle

Telephone repeater

Tesla coil transformer

Wireless communication

Dr Martin Cooper, a former general manager for the systems division at Motorola, is considered the inventor of the first portable handset and the first person to make a call on a portable cell phone in April 1973. Teslas coil was the basis on all wirelless communications.

since the beginning of time

A scientist who studies Earth's land forms is called a geomorphologist. They investigate the processes that shape the Earth's surface and the features that result from these processes, such as mountains, valleys, and coastlines.

Stratification refers to the layering or arrangement of different materials or substances. It is important to earth scientists because it provides insights into the geological history of an area, including past environmental conditions and processes that have shaped the Earth's surface. By studying these layers, scientists can better understand the evolution of the Earth and predict future changes.

Tesla invented the alternating-current generator that provides your light and electricity, the transformer through which it is sent, and even the high voltage coil of your picture tube. The Tesla Coil, in fact, is used in radios, television sets, and a wide range of other electronic equipment - invented in 1891, no-one's ever come up with anything better.

Nikola Tesla was an inventor and a mechanical and electrical engineer.
