Scientists

Edward Jenner(17 May 1749 - 26 January 1823) was an English scientist who studied his natural surroundings in Berkeley, Gloucestershire, England. Jenner is widely credited as the pioneer of smallpox vaccine, and is sometimes referred to as the 'Father of Immunology'. Jenner's discovery 'has saved more lives than the work of any other man'.

Jonas Salk (October 28, 1914 - June 23, 1995) was an American medical researcher and virologist, best known for his discovery and development of the first safe and effective polio vaccine.

Physics (and math).

To ensure that no no matter what country you are working in, the units of measurement you are using are the same across the world and therefore that experiments are repeatable.

No. He was Caucasian, of Scottish birth.

Nikola Tesla was the name of a very influential scientist in the 20th century. Among other things, it was he who developed alternating current, and the main machines involved in processing it.

Isaac Newton and Edwin Powell Hubble

with me

They both are brilliant and it depends if we are talking math then probably Albert Einstien but if we are talking inventing then either Franklin or MARIO

Yes. They think the earth's crust (where we are right now), is broken into huge plates (the continents) that fit together, but move very slowly. Thank you for asking.

They don't decay.

Newton did not believe that light acted like waves, but like small particles which he called corpuscles ( not like blood cells).

An example ... shoot a shotgun toward an open window with a large piece of carbboard outside. Shoot many times to get many 'particles' to hit the cardboard. There should be a discernable figure of the window. Now shine light thru the window and the same pattern shows up on the cardboard. He thought that this proved that light was mado of millions and millions of small particles,

Both need to know quite a lot about math, and science in general.

Wireless communication is the transfer of information over a distance without the use of electrical conductors or "wires". The distances involved may be short or long. When the context is clear, the term is often shortened to "wireless". Wireless communication is generally considered to be a branch of telecommunications. With his newly created Tesla coils, the inventor soon discovered that he could transmit and receive powerful radio signals when they were tuned to resonate at the same frequency. When a coil is tuned to a signal of a particular frequency, it literally magnifies the incoming electrical energy through resonant action. By early 1895, Tesla was ready to transmit a signal 50 miles to West Point, New York... But in that same year, disaster struck. A building fire consumed Tesla's lab, destroying his work. In England, a young Italian experimenter named Guglielmo Marconi had been hard at work building a device for wireless telegraphy. The young Marconi had taken out the first wireless telegraphy patent in England in 1896. His device had only a two-circuit system, which some said could not transmit "across a pond." Later Marconi set up long-distance demonstrations, using a Tesla oscillator to transmit the signals across the English Channel. Tesla filed his own basic radio patent applications in 1897. They were granted in 1900.

Marconi's first patent application in America, filed on November 10, 1900, was turned down. Marconi's revised applications over the next three years were repeatedly rejected because of the priority of Tesla and other inventors.

I think there are many character traits and habits that would make a good epidemiologist. I think the most important thing for epidemiologist would be for them to have to really know about all different types of diseases. I think that they have to be smart about the diseases. They have to know how the diseases spread and how they got it. I think epidemiologists should have some good habits too. I think they should be things like working with diseases. If they are working on a project, then I think whenever they have some extra time, they should work on their project so that they get it done faster. I think another habit they should have is reading. If they read more, then they could learn more vocabulary and more about what they are working on depending on the book they read. - I wasn't going to answer this but my own sense of ethics requires it! So, at the risk of controversy, no one, scientist or not, can compromise truth, even religious truth as they know it, without compromising their own person integrity or ethics. Truth is truth.

US astrophysicist Neil DeGrasse Tyson is 59 years old (birthdate: October 5, 1958).

The salt present in sea water lowers its freezing point.

Though history books continue to give Guglielmo Marconi credit for the invention of radio, Tesla's lectures on wireless broadcasting precede Marconi's radio patents by some three years. The U.S. Supreme Court ruled on the matter in Tesla's favor, and struck down Marconi's patent claim, in 1943.

Science is all about studying how things work. The Sun is just one of many objects studied by scientists.

Geologists

Neil deGrasse Tyson was born in Manhattan, New York City. He was born on October 5, 1958.

Descartes' theory provided the basis for the calculus of Newton and Leibniz, by applying infinitesimal calculus to the tangent line problem, thus permitting the evolution of that branch of modern mathematics. This appears even more astounding considering that the work was just intended as an example to his Discours de la méthode pour bien conduire sa raison, et chercher la verité dans les sciences (Discourse on the Method to Rightly Conduct the Reason and Search for the Truth in Sciences, better known under the shortened title Discours de la méthode). Descartes' rule of signs is also a commonly used method in modern mathematics to determine possible quantities of positive and negative zeros of a function. Descartes created analytic geometry, and discovered the law of conservation of momentum. He outlined his views on the universe in his Principles of Philosophy. Descartes also made contributions to the field of optics. He showed by using geometric construction and the law of refraction (also known as Descartes' law) that the angular radius of a rainbow is 42 degrees (i.e. the angle subtended at the eye by the edge of the rainbow and the ray passing from the sun through the rainbow's centre is 42°). He also independently discovered the law of reflection, and his essay on optics was the first published mention of this law.[7] One of Descartes most enduring legacies was his development of Cartesian geometry, the algebraic system taught in schools today. He also created exponential notation, indicated by numbers written in what is now referred to as superscript.

Thomas Alva Edison could not hear with one of his ears, because he was part deaf. The question arises- why Edison, with thousands of brilliant discoveries to his credit did not invent a hearing aid for himself? The answer was simple. He himself answered it. If someone is partly deaf, people will have to talk to him in a very loud voice. That means lies cannot be told to him, for fear of others learning that someone is telling lies to that poor deaf person. True, we cannot shout lies. Edison himself said that he was somewhat deaf and lucky, so that he had not have to hear any lies from anyone.

It might be Ahmed Zewail whom I have drawn from the wikipedia list of Egyptian scientists.
