Did Dmitri Mendeleev discover the atom?
No. The concept of the atom was postulated by Ernest Rutherford in 1911 and Niels Bohr in 1913, based on the Greek term for the smallest (uncuttable) part of a substance.
Dmitri Mendeleev (1834-1907) is the Russian scientist credited with establishing the modern form of the Periodic Table of elements, in the 1860's.
Why was Tesla not a practical man?
To everyone who studied his life, Tesla was a practical man. He did not really theorize too much about his work, but he got it done better that anyone else from his time. He said this about Edison:
If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found the object of his search.. I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor.
This quote make us sure he was a practical man then comes the other part. As a genius, he was not a practical man. He came with inventions and theories that genius of that time could not comprehend. Tesla kept in touch with Einstein via letters. He went over some theories over some times. Éinstein made clear that he was the greates mind in the world so far and he was not a practical man because he gave his life to realize his visions, while others made millions with his inventions. In the end, he wound up a penniless and forgotten man.
How do scientists determine the evolutionary relationship among species?
They use a taxonomic map to help classify organisms. The placement of organisms on this was originally based on similarities between species. Today we are able to look at their actual genes, which has resulted in a better understanding of evolutionary relationships - or the lack of them- and has resulted in some re-classification.
How much longer do most scientists believe the Sun will radiate?
Most scientists believe that the Sun will continue to radiate for another 5 billion years. This is because the Sun is in the middle of its main sequence phase, where it fuses hydrogen into helium. Once the hydrogen fuel runs out, the Sun will evolve into a red giant and eventually become a white dwarf.
What was Nikola Tesla famous for?
Nikola Tesla was famous for his work in developing alternating current (AC) electrical systems, as well as numerous inventions and innovations in the field of electrical engineering and wireless communication.

How do i conduct an experiment to prove this. and what are the aparratus needed?
Before I answer this question, let me explain what ecosystem means. An ecosysem is an area with populations of different species that interact with each other and its non living factors such as water and soil. In an ecosystem there are many food chains. An example of a food chain is: sun->plant->mouse->hawk. When human hunt the hawks the mice get over populated. That is how human effect ecosystems.
What was Hahn's contribution to the atom?
Heisenberg along with Schrodinger formulated Quantum Mechanics, it is the theory that replaces classic Newtonian mechanics in the world of atoms and molecules. Heisenberg also played a significant role in propelling the world into the nuclear age. After the war, German scientists including Heisenberg took credit for diverting the regime from pursuing a bomb, for moral as well as practical reasons.
What year did Nikola Tesla discover alternating currents?
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.
What atomic theory did Werner Heisenberg discover?
Werner Karl Heisenberg was a renowned German physicist and philosopher. In 1925 he discovered a way to formulate quantum mechanics with matrices. As a result of his discovery, Heisenberg was awarded the Nobel Prize for Physics in 1932.

How did Albert Einstein change history?
Albert Einstein changed history by figuring out that E=mc2 that helped make the atomic bomb.
Also Albert Einstein had the theory of relativity which helped us find out that if we traveled at the speed of light atoms time would move slower for us and we would live longer.
Did Tesla or Guglielmo invent the radio?
Nikola Tesla is now credited with being the first person to patent radio technology; the Supreme Court overturned Marconi's patent in 1943 in favor of Tesla. 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. 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
What did Nikola Tesla invent and are they still being used today?
Tesla is best known for his many revolutionary contributions to the discipline of electricity and magnetism in the late 19th and early 20th century. Tesla's patents and theoretical work formed the basis of modern alternating current electric power (AC) systems, including the polyphase power distribution systems and the AC motor Dr. Tesla's inventions and developments include the ac motor, the bifilar coil, various devices that use rotating magnetic fields, the alternating current polyphase power distribution system, the fundamental devices of systems of wireless communication (legal priority for the invention of radio), radio frequency oscillators, devices for voltage magnification by standing waves, robotics, logic gates for secure radio frequency communications, devices for x-rays, apparatus for ozone generation , devices for ionized gases, devices for high field emission, devices for charged particle beams, methods for providing extremely low level of resistance to the passage of electrical current,means for increasing the intensity of electrical oscillations, voltage multiplication circuitry, devices for high voltage discharges, devices for lightning protection, the bladeless turbine, and VTOL aircraft
