Who was Nikola Tesla influenced by?

Nikola Tesla used ancient Sanskrit terminology in his descriptions of natural phenomena. Nikola Tesla was much impressed to hear from Swami explanation of the Samkhya cosmogony and the theory of cycles given by the Hindus.

Swami Vivekananda was born in Calcutta and he was inspired by his teacher, Ramakrishna.

How does Anders Celsius'e thermometer work?

Anders Celsius' thermometer works based on the principle that liquids expand when heated and contract when cooled. The mercury or alcohol inside the thermometer rises or falls in a calibrated tube to indicate changes in temperature. Celsius defined the scale so that 0 degrees represents the freezing point of water and 100 degrees represents the boiling point of water.

What were some improvments on the tesla coil?

Tesla coil, invented in 1891, is still used in radio and television sets and other electronic equipment. Tesla is considered one of the outstanding intellects who paved the way for many of the technological developments of modern times. All wireless comunication is based on the Tesla coil.

What improvments did Nikola Tesla make on the Tesla coil?

A tesla coil produces vibrations of electricity in the air. These vibrations are the basis upon nearly all wireless communication today. The reason they are popular is because a tesla coil can be adjusted to make what looks like small lightning bolts. During his brief peropd of poularity Tesla with his coil created spectacular displays of live electricity, such as the 1893 Worlds Fair in Chicago.

Which scientist discovered why things sink or float?

Archimedes, an ancient Greek scientist, discovered the principle of buoyancy, which explains why objects sink or float in a fluid. He realized that an object will displace an amount of fluid equal to its own weight, leading to the concept of buoyant force.

What improvements did Nikola Tesla make to his inventions?

Nikola Tesla made improvements to his inventions by enhancing the efficiency of his electrical transmission systems, such as the development of the Tesla coil for wireless energy transfer. He also refined his alternating current (AC) motors and generators to increase their performance and reliability. Additionally, he improved upon existing technologies for generating high-frequency electrical currents for various applications.

What is a tool that helps scientists images of atom and molecules?

There are a couple of possible answers to this depending on what you mean. Visualization software is sometimes used to generate pretty color pictures of molecules. These aren't images of actual molecules, but they're often used to help understand or describe the structure or properties of molecules. A scanning tunneling microscope (STM) is capable of detecting individual atoms. It doesn't use visible light, but it's possible to process the data into an image.

Who was one of the greatest scientists of modern history who predicted things about splitting the atom?

One of the greatest scientists of modern history known for predicting the potential of splitting the atom was Albert Einstein. His work on the theory of relativity laid the groundwork for understanding the relationship between mass and energy, eventually leading to the development of atomic energy and the atomic bomb.

What did Marie Curie invented?

she and her husband Pierre Curie discovered radiation and radium.
Marie Curie did not invent anything but she discovered Radium and did a lot of work on radioactivity in the 1800s.

What did people name Nikola Tesla?

the man out of time. (submited by killa shy guy)

Who is Nikola Tanjga?

Nikola Tanjga aka Fagdulah or Kreten, is a crazy serb kunt

What is a scientist who studies heredity called?

A scientist who studies heredity is called a geneticist. Geneticists study genetics in general, which includes heredity.
A scientist that studies heredity is called a geneticist. They study general genetics. Heredity is the genetic transfer of characteristics from generation to another.

Basic unit for measuring time?

The basic unit for measuring time is the second. It is defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom.

How did francis crick and James Watson try to understand the structure of DNA?

Francis Crick and James Watson used data from other scientists, including Rosalind Franklin's X-ray crystallography images, to hypothesize and build models of the DNA molecule. They focused on creating a model that showcased how the double helix structure of DNA could explain its functionality in carrying genetic information. Their work ultimately led to the discovery of the double helix structure of DNA in 1953.

Where do you use a Tesla coil?

A tesla coil produces vibrations of electricity in the air. These vibrations are the basis upon nearly all wireless communication today. The reason they are popular is because a tesla coil can be adjusted to make what looks like small lightning bolts. During his brief peropd of poularity Tesla with his coil created spectacular displays of live electricity, such as the 1893 Worlds Fair in Chicago.

What is the study of inheritance triats called?

The study of inheritance traits is called genetics. It focuses on how traits are passed from parents to offspring through genes and how variations in genes contribute to different traits and characteristics in individuals.

What did Louis Pasteur invented?

He developed the first vaccine against anthrax, a deadly bacterial disease that affects both humans and animals and he proved that the idea of spontaneous generation was not true, through a year-long experiment. He was also involved in a lot of experiments in microbiology and is regarded as a very well known Biologist.

When did tesla invented the fluorescent light?

It was Alexandre-Edmond Becquerel who first conceived the idea of placing a fluorescent coating on the inner surface of a high voltage gas discharge tube but he didn't quite made it work properly. Tesla's investigations in the area of high-voltage RF power processing techniques did result in the very first high efficiency, high frequency lighting ballasts in 1892.

How did scientists reach their conclusions during the middle ages?

During the Middle Ages, scientists relied heavily on philosophical and religious beliefs to guide their research and conclusions. They often used deductive reasoning based on previous knowledge rather than experimental evidence. The Church also played a significant role in shaping scientific thought during this time period.

How did Albert Einstein deal with depression?

He did enjoy smoking tobacco, which contains nicotine. Read on to see why that might have helped w/ his depression.

Scientists have established that people prone to depression are twice as likely to be smokers, and are less likely to succeed in quitting smoking after taking up the habit, according to McClernon. The Duke study explored the theories behind the higher smoking rates among people experiencing depression.

"Smokers may be more prone to depression than nonsmokers," said Edward Levin, Ph.D., a professor of biological psychiatry and researcher at the Duke center, who was senior investigator in the current study. "Or, people with depression may be self-medicating by smoking, albeit in a deadly way."

In the study, the researchers recruited 11 people who did not smoke but who were experiencing symptoms of depression. Participants were randomly assigned to wear either a nicotine patch or a placebo patch that did not contain any nicotine. The researchers used a standardized method, a 20-item questionnaire called the Center for Epidemiological Studies Depression scale, to measure depression symptoms among the study participants.

"Despite the small number of participants, this is the largest study of its kind," McClernon said.

The team found that participants who wore the nicotine patch for at least eight days experienced a significant decline in their depression-assessment rating scores. McClernon said this finding indicates that the drug led to an improvement in depression symptoms.

As a possible explanation for how nicotine exerts its beneficial effect, McClernon said: "The same areas of the brain that are stimulated by nicotine appear to be involved in the regulation of mood."

Nicotine stimulates the release of specific neurotransmitters, including serotonin, dopamine, and norepinephrine, which carry messages between nerves cells. Depression has been linked to chemical imbalances of these neurotransmitters, McClernon said.

What is the functions of Pasteur salt solutions in fermentations?

The pasteur salts in solution act as a buffer to any acids the yeast may create. Since yeast only converts sugar (most likely sucrose or glucose) to ethanol under anaerobic conditions, and it is unreasonable to assume that there will be no oxygen present in the laboratory, some acetic acid is created as a result. The pasteur salts act as buffers to the acidity so that the proteins in the yeast do not become denatured. Hope this was the answer you were looking for

What is the first middle and last name o Nikola Tesla?

Nicola Tesla was an Istro-Romanian. His real name was Nicolae Teslea. His father was the Orthodox priest Milutin Teslea. The original name of the family was Draghici (a name common also in Romania) but changed with the nicname "Teslea", which in both Istro-Romanian and Romanian means bass (the carpenter's tool) and in Serbian means nothing. His family was one of carpenters.
