Why would a scientist use berzelius's systern of representing elements?
The reason is because it is a system that uses letters called chemical symbols, which are a shortned way of writing the names of elements.
He/she is precise.
--Answer-- Assuming that the "known value" is actually correct, then this scientist is likely performing the experiment/observation wrongly (and as the saying goes if you keep doing what you've been doing, you'll keep getting what you've been getting). Wrongly here may mean that the equipment is not correct or is not correctly calibrated, or that the quantities are not correct.
Which scientist developed a new system of grouping organisms in the late eighteenth century?
Carolus Linnaeus
Which scientific unit of measure is not named for a scientist of inventor?
liter, meter, candela (light), gram, second, atmosphere (air pressure)
Thomas Harvey was a pathologist. In 1955, he conducted the autopsy of Albert Einstein.
.
List five ways that scientists are able to communicate their discoveries?
cell phones . computers. media or press. books and 1 more.
done by a.w.
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.
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.
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.
Which is a method that scientists use to determine the composition of Earth's layers?
Shooting seismic waves into the planet
Is Mr Roy Woodall an Australian scientist?
Roy Woodall headed Western Mining Corporation's Exploration Division in Australia for several decades. He retired in the mid 1990s. He is one of the greatest explorationists in the post-war era. An extremely intelligent, but unassuming and humble leader that allowed his teams great flexibility to focus on the big picture. At a conference in Kalgoorlie (Western Australia) he once said "Discovery begins with a Bold and Fertile Vision". A quote that resonates in the hearts and minds of a generation of geologists. He is credited with leading teams to the discovery of the world-class Kambalda Nickel Field, the Perserverance Nickel deposit, the Mt Keith and Rocky's Reward deposits and the what is arguably world's greatest polymetallic deposit the Olympic Dam copper-gold-uranium deposit in South Australia.
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.
How does technology help scientists?
A classic example would be the development of better lenses and of ways of using lenses together. Biologists are able to study many species without the need to get close to them, using binoculars. Microbiologists have discovered and studied an enormous number of species using microscopes. Astronomers still use optical telescopes to advance knowledge of the sky.
What scientist used flasks to support the theory of biogenesis?
Louis pasteur was the one to support th theory of biogenesis.
How do scientists and historians differ in their work How are their jobs similar?
Scientists work on different stuff then historians do.
What type of salt concerns scientist the most?
Scientists are very concerned about the Hypotyte Uranium Salt, its consumption is said to have blinding and deafening side effects. Those under the influence of said mythical salt are instilled with what can only be described as 'seer-like wisdom'. Origins of such salts have been recorded is areas such as: -Jerusalem -China -India -Dragons -Dragonia
What can the scientist infer about the relationship of the nebula and the pulsars life cycle?
Nebulas are interstellar clouds made of dust and gases and a pulsar is a kind of star. A pulsar is formed inside of a nebula, therefore a scientist could conclude that without a nebula a pulsar could not exist.
