What is Albert Einstein's native country?
Germany.
Einstein was born in Ulm, Germany in 1879. He moved to the US in 1933 to escape the Nazis (he was a Jew) and became a US citizen in 1940. His most famous and probably significant works on special relativity (1905) and general relativity (1916) were published long before his move to the US.
Are scientists or artists more respected in your society?
Basically, i think whichever one inspires you more. It depends on the individual. I'm inspired by science in general.....I'm awed by it. My mother is an architect, she would say artists make the world more of a colorful and vibrant place. Her excitement is in the art of the world....all types. My excitement is in the wonders and research of clinical "why's" and "hows."
It's all in how you look at the world, and what keeps your brain stimulated
What were the circumstances of Hammergren's life?
grew up in a tiny community in Minnesota in a family to which he attributed his strong moral and ethical values as well as his knowledge of business. His father, a traveling salesman in the healthcare business
What did F. Matthias Alexander discover?
He found that he was holding his head and neck too far forward, and that these unconscious patterns were the source of the tension in his body that was harming his voice.
Why the shape of very small object and very big object is spherical?
This is an outstanding question. On the atomic and molecular scale rotation tends to determine the spherical shape. Molecules do tend to organize in a spherical manner on a large scale as rain drops. However, should the raindrop grow too large as it falls neck instability tends to give it a barbell shape in which it will break into more than one sphere.
But besides rotation for planets they tend to "organize" around a center of mass and gravitational forces are at work here. I welcome additional comments on this subject.
A person who studies water and its properties?
A person who studies water and its properties is called a Hydrogeologist.

Who proposed the modern idea of an element and when?
Robert Boyle proposed a definition of chemical elements that led to the currently accepted definition. His definition is strikingly similar to Aristotle's earlier definition. In The Sceptical Chymist (1661) Boyle wrote, "I now mean by elements … certain primitive and simple, or perfectly unmingled bodies; which not being made of any other bodies, or of one another, are the ingredients of which all those called perfectly mixed bodies [chemical compounds] are immediately compounded, and into which they are ultimately resolved." However he also declared that elements must be identified by experiments, not by "pure reason" as Aristotle had identified his four classical elements.
In 1789 Antoine Lavoisier published a list of chemical elements based on Boyle's definition.
In 1803 John Dalton proposed (as part of his atomic theory) that all atoms of an element have identical properties (including mass), that these atoms are unchanged by chemical action, and that atoms of different elements react with one another in simple proportions.
in 1869 Dmitri Mendeleev was the first to publish a periodic table of the then known elements similar to the one used today.
Many other scientists also made contributions to this idea over time.
What features of binomial nomenclature make it useful for scientists of all nations?
Because a binomial nomenclature is a universal name, that refers to the same thing throughout all countries, regardless of language. Latin is universal for two reasons: 1) historicaly scientists used this language; that practice has been on-going for some time, so there is a predominance of Latin terms in science. This tends to encourage all scientists to learn some Latin, which perpetuates its usefulness. 2) It is a "dead" language in that no one speaks it natively. Therefore it will no longer change. Therefore it is consistent and so easy to use.
What did Democritus say about the that has been proven true?
he taught a lot about Atoms. at the time they thought his theory to be true- but as science advanced so did our thinking. you might wanna check out this link; en.wikipedia.org/wiki/Democritus
How can if different units are used in measurement problems be overcome by using SI unit?
If you have different units, converting to any common unit will help. Of course, using standard units, i.e. SI units, is better than any other arbitrary unit. Also, SI units for a consistent set of units; as a result, you can often omit proportionality factors from formulae.
Who was the first scientist to make sulphuric acid?
It is unclear who actually was the first scientist to prepare sulfuric acid. Johann Van Helmont is often given credit, as the scientist who first prepared it, ca.1600.
Related Information:
There is documentation referring to it, dating from about 2600 years ago (appearing on a Sumerian list). So we know that there must have been preparation, and uses for it, prior to that. Documentation from about the beginning of the Common Era show that many physicians, scientists, alchemists, and philosophers observed, used, and worked with it. It is likely that some of these prepared it for themselves, but no documentation exists as proof of who or when.
How does sound affect frequency?
The definition of sound is :
"Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear."
Sound can be measured by amplitude (loudness) and pitch (The frequency of the vibrations).
Therefore sound does not affect frequency but frequency affects the pitch of the sound.
Name the scientist whose name begins with ham is ham radio?
There is no scientist named Ham in ham radio. The term was first an insult, like "ham-fisted" (clumsy) or "ham actor" (bad stage actor). Then the radio operators decided to take the name as a source of pride, and found three radio pioneers to say it was named for:
The H is for Heinrich Hertz, who did a lot of work with radio frequency energy and for whom the measurement of frequency is named.
The A is for Major Edwin Armstrong, who invented frequency modulation. Apparently no one else was available because FM wasn't a popular mode in the amateur service when they borrowed his name.
The M is for Guglielmo Marconi, who invented the radio.
No, Nikola Tesla was an Orthodox Christian, and his father, Fr Milutin Tesla, was a Serbian Orthodox priest.
Tesla was very spiritual but he did not belong to any religion.
