Name famous scientist in periodic table?

Answer: There are 13 elements named after people, although only 12 of the names are formally accepted by the International Union of Pure and Applied Chemistry (IUPAC).

  • bohrium (Bh, 107) - Niels Bohr
  • curium (Cm, 96) - Pierre and Marie Curie
  • einsteinium (Es, 99) - Albert Einstein
  • fermium (Fm, 100) - Enrico Fermi
  • gallium (Ga, 31) - both named after Gallia (Latin for France) and its discoverer, Lecoq de Boisbaudran (le coq, the French word for 'rooster' translates to gallus in Latin)
  • hahnium (105) - Otto Hahn (Dubnium, named for Dubna in Russia, is the IUPAC-accepted name for element 105)
  • lawrencium (Lr, 103) - Ernest Lawrence
  • meitnerium (Mt, 109) - Lise Meitner

Who or what influenced Tesla to invent what he did?

Nikola Tesla said:

The gift of mental power comes from God, Divine Being, and if we concetrate our minds on that truth, we become in tune with this great power. My Mother had taught me to seek all truth in the Bible.

In the Bible, in the book of Job, chapter 38 verse 35 gave him the clue. It says:

(Do you send the lightning bolts on their way? Do they report to you, 'Here we are'?)-----

Nikola Tesla's transalation: Do you use electricity to send or receive messages?

Nikola Tesla understood the future through this passage. Latter in life he came with AC and wireless technology.

What was Nikola Tesla's area of science?

His specialty was electricity. Check out his patents.

What could be treated as a result of Alexander Fleming's discover of penicillin?

Alexander Fleming's discovery of penicillin came about by accident.

Fleming was an untidy worker, often leaving his equipment uncleaned. When he went away for a holiday during 1828, he left a clutter of plates growing various bacteria lying about his desk. After he returned, whilst working on an influenza virus he noticed that mould had grown on a staphylococcus culture plate. Not only that, the mould had created a bacteria-free circle around itself. Working on an hypothesis, he experimented further to determine that even a weaker-strength mould culture prevented growth of staphylococci. Thus, Fleming initiated the development and practice of antibiotic therapy for infectious diseases.

What was Nikola Tesla first idea?

Nikola Tesla states

there is a possibility of obtaining energy not only in the form of light, but motive power, and energy of any other form, in some more direct way from the medium. The time will be when this will be accomplished, and the time has come when one may utter such words before an enlightened audience without being considered a visionary. We are whirling through endless space with an inconceivable speed, all around us everything is spinning, everything is moving, everywhere is energy. There must be some way of availing ourselves of this energy more directly. Then, with the light obtained from the medium, with the power derived from it, with every form of energy obtained without effort, from the store forever inexhaustible, humanity will advance with giant strides. The mere contemplation of these magnificent possibilities expands our minds, strengthens our hopes and fills our hearts with supreme delight. . . . - "Experiments With Alternate Currents of Very High Frequency and their Application to Methods of Artificial Illumination," 1891

that was his primary idea since he was a boy. If you are talking about his first invention, it was the tesla telephone repeater.

What were Nikola Tesla's parents jobs?

Milutin Tesla was a priest.

Georgina-Djuka was an illiterate, but an extraordinarily gifted woman. (Housewife)

What is a Turf Scientist?

A turf scientist is someone who studies turfgrass. Turfgrass is a term used to describe a grass used for a specefic function such as golf course fairway, a sports field, or a home lawn. A turf scientist implies this person has some formal education within the said subject area. This education is most often from an accredited university for an associates, bachelors, masters or PhD in turfgrass science.

How come scientists can't test the theory on which the particle model is based?

The particles of all substances are always moving, so we can only measure the average speed of them, which is called temperature. Also, particles are very small, and they are hard to see and measure.

Who are the scientists behind the atomic bomb of World War 2?

The key scientists involved in the development of the atomic bomb during World War II were J. Robert Oppenheimer, Enrico Fermi, and Leo Szilard as part of the Manhattan Project led by the United States. These scientists played crucial roles in the theoretical and experimental work that led to the successful creation and deployment of the first atomic bombs.

What can scientist do to help solve the problem concerning fossil fuels?

Scientists can develop alternative energy sources such as solar, wind, and geothermal power to reduce dependence on fossil fuels. They can also research carbon capture and storage technologies to mitigate greenhouse gas emissions from burning fossil fuels. Additionally, scientists can work on improving energy efficiency and promoting sustainable practices to reduce overall fossil fuel consumption.

Max Planck's work with atoms correlated energy to...?

Max Planck's work with atoms correlated energy to the frequency of radiation emitted or absorbed by atoms, leading to the development of quantum theory.

How do you use discover in a sentence?

The word discover is a verb so you may use it in a sentence like this: Amerigo Vespucci was the first explorer to navigate and discover the coastal areas of the Americas without thinking that it was India.

Why do you think that many people persist to visualizing the atom according to the out-dated Bohr model as opposed to accepting the quantum mechanical model?

The Bohr model is simpler to understand and has been widely taught in school for many years, leading to familiarity and potentially a reluctance to accept new information. Additionally, the Bohr model provides a more tangible representation of an atom's structure compared to the abstract nature of the quantum mechanical model, making it easier for some to conceptualize.

When did Nikola Tesla's father die?

Nikola Tesla's father, Milutin Tesla, died in 1879.

Was Nikola Tesla afraid of misuse?

Yes, because he didn't want other people to use his inventions for the wrong purposes. A good example of misuse from Tesla's alternating current was when Thomas Edison used the alternating current to shock and kill animals, thus trying to prevent other people from using Tesla's inventions.

What are some goals that Nikola Tesla set for himself?

Some of Nikola Tesla's goals included developing wireless power transmission, harnessing renewable energy sources, and improving communication technologies. He also aimed to create inventions that would benefit society and advance scientific knowledge. Tesla was driven by a desire to make significant contributions to humanity through his innovative ideas and visionary inventions.

What is one of Nikola Tesla major discoveries?

Tesla was a different kind of person, inventor and genius. He was a pioneer of electrical apparatus, methods,and principles which continue to influence every aspect of our electrical world.
