What rules do you have to follow to be a scientist?
you have to have a love for science, you have to have good grades too. You also have to have a degree in the sciences and go to a good college.
He didn't.
Many people 'could' take credit for the invention of the radio - and Tesla has his place in the list, but not for either discovering, inventing of it. If you want to know the inventor of radio, technically that might be a guy named Maxwell who theorized EM transmissions could be used to produce something like radio waves.
The first real work with Radio waves was done by Heinrich Rudolf Hertz between 1887 and 1890. He believe it or not didn't think his research was of any real use to people at the time. :)
Guglielmo Marconi would be the first to actually create a fully functioning system, and is generally considered the 'inventor of radio'. It's these patents that were reversed after the start of WWII that allowed Tesla's American Patents to give him credit for invention that confuse people. Marconi, being Italian - and not one of the Allied countries - and being nominated by Musolini as the Head of the Facsist Grand Council ... well, even though he died in 1937 - he lost his patents right after America went to war in 1943. Probably wasn't right that it happened but it did. As a result Tesla's patents were put in place and Tesla got revisioned in as a genius for inventing radio.
In reality - Tesla didn't think radio waves were real. Tesla thought that Maxwell, Lodge, and Hertz - pretty much everyone else -- was wrong in their findings that airborne electromagnetic waves (radio waves) existed. Tesla thought it was what he called "electrostatic thrusts", with the real signals being conducted by Earth currents and not through the air at all. So calling him the father of Radio is really misleading. He patented a model boat that used circuits he - frankly didn't understand - and demonstrated it to the press. For that, he got credit.
So Marconi was the first real long distance radio inventor. Reginald A. Fessenden will come along and introduce radio with audio (voices) in 1907 and then things really took off as we know them today.
It is notable that in the Blizzard of 1888 trains used a device created by Thomas Edison to transmit messages - it's beleived this is the first 'SOS' ever sent, but it used limited field induction - and although wireless communication, isn't generally considered a 'radio'. The earliest patent in wireless communication is from Alexander Gram Bell (inventor of the the Telephone) who created something called the Photophone in 1880 that used light waves instead of radio.
lawlz,
yes they are real. Many different types of brain scientist exist, there are people who study the brain by dissecting dead ones, people who study the brain by experimenting on people( not cutting them open.. sometimes they will connect the person to an MRI and have them perform different brain functions and map out which ares light up with the different functions)..... there are many other types of brain scientist, the study of the human brain is a popular science and the nmber of people who do so is rising.
she is the sister of Louis pasteur who created pasteurization, the rabies vaccine, and lots of other things
What did Irving Langmuir invent?
See the related link. If you read the whole article, it will answer your question better, but in brief, he invented a gas-filled incandescent lamp and hydrogen welding technique.
Most scientists rejected wegner's theory of continental drift because the theory failed to explain?
Wegener's theory didn't explain how the continents could plow through the solid rock of the sea floor, and he was unable to give a convincing explanation of what force could move entire continents.
Which is a method that scientists use to determine the composition of Earth's layers?
Shooting seismic waves into the planet
5 famous historians and give their contributions?
Here are some Classical historians for you:
Thucydides: Ancient Greek Historian who informed us of the Peloponnesian Warbetween Sparta and Athens, and the life and times of the famous Pericles.
Herodotus: The Father of History. Ancient Greek writer who travelled extensively and informed us of geography and politics of the time.
Tacitus: Roman Historian who wrote on the Emperors of the early Principate, their activities against Germany and his father in law Agricola who was commander of the legions in Britain. He tells us much of the Emperor's, their policies and is often our only source in regards to the early Britons.
Arrian: History of Alexander the Great. Wrote on his conquests, life, politics and influences. Best informant we have on the young king.
Suetonius: Roman Historian/Biographer who wrote The Lives of Twelve Caesars, about the early principate. Unlike Tacitus, Suetonius wasn't so much a historian but a purveyor of juicy gossip. Fun to read.
Plutarch: Parallel lives, comparing the lives of famous Greeks and Romans, which linked them according to their achievements, personalities and the way in which they were viewed by their contemporaries.
Cassius Dio: A Greek Roman historian. Wrote on Alexander and Roman History.

What are the scientist conclusion regarding the Bing Bang Theory?
that worms will take over the earth that worms will take over the earth
Why do scientists recognize a boundary between layers at about 12 kilometers above sea level?
the way the altitude changes the temperature changes
How do scientists know that a new theory is accurate?
Because all of the observations and evidence are used for support.
John Richard Bond is an astronomer and a member of the Canadian Institute for Advanced Research and helped establish the Canadian Institute for Theoretical Astrophysics.
What do scientists think will eventually happen to the universe?
the sun will turn into a red giant and everything willl melt then we it will peacefully turn to a white dwarf.
Which tool allows scientists to see patterns on a carbon molecules?
I don't really know....... BECAUSE THAT'S MY QUESTION!
How do scientists currently describe the movement of electrons around the nucleus?
The short answer is the motion is completely deterministic, but not predictable in the everyday, macroscopic sense. The more accurately you try to measure momentum of the electron in transit, the less you will know about its position.
A scientist makes a claim of having discovered an eternal life potionIs this a testable hypothesis?
The hypothesis would have to be phrased in such a way as to allow for experimenting, but yes.
What 2 things does a life scientist use to identify living things?
The main two characteristics of living things are: -The ability to grow -A consistency of cells
