Are all of Nikola tesla's siblings older than him?

No, he was the fourth child of five. One sister was younger.

Is Nikola Tesla Russian?

Nikola Tesla was not Russian; he was born in what is now Croatia in 1856. He was a Serbian-American inventor and engineer known for his work in developing the modern alternating current (AC) electricity supply system.

What scientist made a major contribution to society?

Marie Curie made a major contribution to society through her groundbreaking research on radioactivity, which led to the development of X-rays and radiotherapy for cancer treatment. She was the first woman to win a Nobel Prize and remains an iconic figure in the field of science.

What does it mean when a scientist rejects a hypothesis?

When a scientist rejects a hypothesis, it means that the data or evidence does not support the initial proposed explanation for a phenomenon. This rejection prompts the scientist to reconsider the hypothesis, gather more data, or formulate a new hypothesis that better fits the observed results.

Who is the scientist who suggested that atoms contain a hard core containing most of the mass of an atom?

The scientist that suggested and proved that atoms contained a nucleus in which most of the weight of the atom was contained (in a very small volume) was Ernest Rutherford, in 1909.

This was shown in the 'gold foil' experiment. This was made by shooting positively charged alpha particles, or a positively charged helium atom (2 protons, 2 nuetrons). these then when shot at the gold foil. some of the alpha particles just passed through the gold foil, but some were deflected. this proving that some hit the nucleus while others did not.

Why the scientists know that there are 60 carbons in buckminsterfullerene?

Scientists know that there are 60 carbons in buckminsterfullerene because the molecule's structure is a perfect sphere composed of 12 pentagons and 20 hexagons. Each carbon atom in buckminsterfullerene forms three bonds, creating a cage-like structure with 60 carbon atoms.

Do you write a conclusion before the results in a chemical experiment?

In a scientific paper or report, the conclusion usually comes after the results section. The results section presents the raw data and findings, which are then interpreted in the conclusion section to discuss the implications of the results and how they support the hypothesis or research question.

When did Nikola Tesla meet Thomas Edison?

Nikola Tesla was referred to Edison by a mutual friend. Tesla emigrated to New York and gave a recommendation letter to Edison who hired him to help develop DC power systems. Their partnership did not last long. Instead of working on DC power as Edison challenged him, Tesla chose to improve Faraday's AC power. Edison would not listen to Tesla's arguments for AC power, and Tesla quit. George Westinghouse then bought Tesla's AC patents, and directly challenged Edison in the current wars which Westinhouse eventually won. Ironically, many devices used today are DC (computers, cell phones, LED lights, etc.) as Edison predicted, and converters have to be used to step down from AC back to DC.

To learn from a model scientist must?

To learn from a model scientist, one must observe their methodologies, ask insightful questions, and seek mentorship to understand their approach to research and problem-solving. It is important to engage in discussions, collaborate on projects, and actively seek feedback to gain insights and knowledge from the model scientist's experiences and expertise.

What was Nikola Tesla's relationship with Robert Underwood Johnson?

Katharine McMahon Johnson was, according to some accounts, the only woman Tesla ever loved. She was the wife of Tesla's lifelong friend, Robert Underwood Johnson. Though the two often exchanged flirtatious letters, their relationship was totally platonic. Not forgetting Tesla even at death, she charged Robert to keep in close touch with him always.

An order for scientific research to be universally understood scientists report measurements in?

Scientists report measurements in standard units such as the International System of Units (SI) to ensure universal understanding. These units provide a common language for researchers to communicate their findings accurately and effectively.

Why did Tesla decide to invent the radio?

Tesla invented the radio as part of his work on wireless communication and transmission of energy. He developed the technology behind radio communication, including the concept of radio waves and the Tesla coil, which laid the foundation for modern radio technology. Tesla's goal was to create a system for transmitting information and energy wirelessly, which he believed would revolutionize communication.

Where did Nikola Tesla invent the induction motor?

In the summer of 1883, Tesla was working in Strasburg, France, where he built his first actual induction motor model and saw it run.That was the first induction motor ever achived and even before the one Galileo Ferrari of Italy invented.

Scientist form what hypotheses to answer questions?

Scientists form hypotheses to propose a possible explanation or answer to a specific question or problem they are investigating. These hypotheses are testable and help guide the research process to determine if the proposed explanation is correct or needs to be revised.

What problems did humphry davy have when he made the light bulb?

Humphry Davy did not invent the light bulb; it was actually Thomas Edison who is credited with its invention. Davy did work on early electric arcs for lighting, but he faced challenges with the short lifespan of the carbon filaments used and the high energy consumption of the bulbs. These issues were later overcome by Edison's development of a longer-lasting filament made of bamboo.

Where was the Tesla coils located?

Tesla coils can be found in various places, such as laboratories for research purposes, museums for educational demonstrations, and music concerts for entertainment. They are often used to produce high-voltage electricity for experimental purposes or to create visual effects.

What system of measurent do most scientists use when collecting data and perfor ming experiment?

Most scientists use the International System of Units (SI) when collecting data and performing experiments. SI units provide a standardized system of measurement that ensures consistency and precision across scientific disciplines.

Why is it important for scientists to behave in an ethical manner?

It is important for scientists to behave ethically to maintain the trust of the public and fellow researchers, uphold the integrity of the scientific process, and ensure the accurate representation of data and findings. Unethical behavior can damage scientific credibility and lead to harmful consequences for society.

What did Pasteur settle the spontaneous generation argument?

Louis Pasteur settled the spontaneous generation argument by conducting experiments that demonstrated the presence of microorganisms in the air and refuting the idea that they could arise spontaneously. His experiments showed that microorganisms enter solutions from the air, leading to the concept of biogenesis, which states that living organisms only come from other living organisms.

When did Louis Pasteur discover germs?

In 1857 Louis Pasteur was employed to find the explanation for the souring of sugar beets used in fermenting industrial alcohol. His explanation was that germs found in the air can multiply under the right conditions.

Who was the first scientist to use the term inertia?

The term "inertia" was first introduced by Galileo Galilei, an Italian physicist and astronomer, in the 17th century. Galileo's work laid the foundation for Isaac Newton's laws of motion.

What do the scientists working on CERN the world's largest atomic accelerator hope to accomplish?

The world's largest particle accelerator is used to accelerate particles to extremely high energies at which they can undergo collisions which, it is hoped, will produce previously unseen kinds of results which will shed light on currently mysterious or unanswered questions about particle physics, thereby increasing human knowledge and our understanding of the way the universe works on a very deep, fundamental level.

How many different elements with unique properties have scientist found?

Scientists have identified 118 different elements on the periodic table, each with unique properties. These elements range from hydrogen, the lightest element, to oganesson, the heaviest synthetic element. Each element's distinct properties determine its behavior and applications in various fields of science and industry.

How many times did Nikola Tesla get injured?

Nikola Tesla was known to have been injured twice during his lifetime. The first was a burn incident in 1895 during a laboratory experiment, and the second was a fall in 1937 that resulted in broken ribs.
