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.

What scientist does not have an element named for them?

This will be a very long list as there are many forms of science. So you might try changing the question to "Which Chemists, discovered elements that they did not name after themselves?"

Or an example is Alexander Graham Bell the inventor of the telephone.

How did Bohr improve Planck's theoory?

Bohr improved Planck's theory by incorporating the concept of quantized energy levels for electrons in atoms. He proposed that electrons could only exist in certain distinct energy levels, which helped explain the stability of atoms and the emission/absorption of light in atomic spectra. This led to the development of the Bohr model of the atom.

Did Nikola Tesla have a brother?

Dane Tesla was the older brother of the Teslas. He died in a horse accident when Nikola was 5 years old.

Did Nikola Tesla get married?

No, Tesla never married
Nikola Tesla was celibate all his life.

How did Theodor Schwann contribute to the microscope?

Theodor Schwann made important contributions to microscopy by using improved lenses to study animal tissues at a cellular level. His work on the development of the cell theory, alongside Matthias Schleiden, laid the foundation for modern cell biology and our understanding of cells as the basic unit of life.

How do you make a Tesla coil?

Difficulty: Moderately Challenging

== * Transformer * 5 sheets of 12 x 12 x 0.032 inch polystyrene * 4 10-inch square metal plates * 4 "L" brackets * 4 bolts with round end caps * One roll heavy gauge wire * One roll enameled wire * One 3-inch diameter PVC tube, 12 inches long * Varnish * Two 1 1/2 inch diameter PVC pipes, 6 inches long * Brass doorknob * 4 additional PVC pipes, slightly taller than transformer * Glue * Wood board == Step1 Find a transformer rated at 9,000 volts or better and 30 milliamps. Many people opt for neon sign transformers, which are relatively easy to find. Others use oil furnace ignition transformers or automotive coil transformers, which produce much more subtle effects.

Step2 Make a capacitor by layering the five sheets of polystyrene alternating with the four metal plates. The plates can be copper or aluminum foil or just very thin aluminum plates.

Step3 Make the spark gaps with the four L brackets and the bolts. Put the round end caps on the ends of the bolts.

Step4 Wrap a heavy-gauge bare wire six or seven times around a cylinder form at least eight inches in diameter. Poke holes in four pieces of PVC pipe and thread the wire through to form your primary coil. The holes in the PVC should be about 1/8 inch apart.

Step5 Wind the enameled wire tightly around the three-inch PVC form for your secondary coil. This one should have about 500 turns. Varnish the coil with several heavy coats and make sure it dries evenly.

Step6 Wrap 20 turns of enameled wire on two separate 1½ inch diameter PVC pipes for your radio-frequency chokes (RFCs). == Step1 Mount the doorknob on top of the secondary coil. This acts as the top discharge terminal. Set the secondary coil inside the primary coil and attach both at the center of the piece of wood.

Step2 Attach the four remaining PVC pipes to the underside of the board. Attach the spark gaps, radio frequency chokes, to the top of the board. Slip the transformer underneath, and put the capacitor on top of the transformer.

Step3 Attach a ground rod to the wire leading from RFC 2 to the primary coil.

What was Nikola Tesla's first job?

His first job in the industry was as an electrical engineer at a telephone company in Budapest, Hungary in 1881. One day as he was walking through the park, he had a vision of a rotating magnetic field. He sketched a drawing of an induction motor on the ground, which was his first great idea.

How did Isaac Newton describe himself?

Newton had said right before dying "I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me."

How many inventions did Nikola Tesla make?

He held 272 patents in 25 countries, with 112 patents in the United States alone. The Tesla coil lives today wich is the basis of wireless communications. All homes are powered with alternate current wich Tesla was the first man to know how it works and made the firt machine to make it.

What is the study of DNA called?

The study of DNA is called genetics. Genetics is the branch of biology that focuses on the inheritance, variation, and expression of genes in organisms.

Can you explain in a pourquoi tale why the sky is blue?

In a pourquoi tale, the sky is blue because it is colored by the tears of a young maiden who cried for her lost love. The sky turned blue from the reflection of her sorrow and longing for her beloved.

What problems did Nikola Tesla solve when he invented the Tesla coil?

A Tesla coil is a type of resonant transformer circuit invented by Nikola Tesla around 1891. The Tesla coil is one of Nikola Tesla's most famous inventions. It is essentially a high-frequency air-core transformer. It takes the output from a 120vAC to several kilovolt transformer & driver circuit and steps it up to an extremely high voltage. He did not have any problems making his coil wich is the basis of wireless communituy today.

When did Galileo become a scientist?

At age twenty, Galileo noticed a lamp swinging overhead while he was in a cathedral. To check how long it took for the lamp to swing back and forth, he used his pulse to time large and small swings. Galileo discovered something that no one else had ever realized: the period of each swing was exactly the same. This made him instantly famous.

Did Nikola Tesla die?

Yes, Nikola Tesla died on January 7, 1943, in New York City. He was a renowned inventor and engineer known for his contributions to the development of alternating current (AC) electrical systems.

What did Nikola Tesla first research?

Nikola Tesla's first research involved developing alternating current (AC) electrical systems, including the invention of the Tesla coil, which laid the foundation for modern electrical power distribution. Tesla also explored wireless communication and transmission, making significant contributions to radio technology.

Who was the first scientist to look at cells under a simple microscope?

The first scientist to observe cells under a simple microscope was Robert Hooke in the 17th century. In 1665, Hooke used a compound microscope to examine a thin slice of cork and described the cells he observed as resembling tiny rooms or cells, giving rise to the term "cell."

What is a scientist who studies heredity?

A scientist who studies heredity is called a geneticist. Geneticists study genes, DNA, and how traits are passed down from parents to offspring, as well as how variations in genes can influence different traits and diseases.

Why must scientists be careful with the evidence they find?

Because all of our knowledge of the past is based of of their evidence and damaging anything not only is equivalent to the loss of hundreds of millions of dollars, it is also a irretrievable loss of knowledge. Furthermore, carelessness may result in misinterpretation of the evidence and/or contamination of the evidence which is even worse than loss, as it may cause incorrect conclusions to be drawn.

The scientist who discovered more than 300 uses for peanuts?

George Washington Carver is credited with discovering over 300 uses for peanuts, including peanut butter, soap, ink, dyes, and wood stains. He was a prominent agricultural scientist and inventor who made significant contributions to sustainable farming practices.

What did Niels Bohr contribute to the atomic theory?

Niels Bohr developed the model of the atom that incorporated quantum theory, known as the Bohr model. This model proposed that electrons orbit the nucleus in fixed energy levels or orbits, explaining the stability of atoms and their emission spectra. His work laid the foundation for modern atomic theory and quantum mechanics.

British scientist who first observed cells under a microscope?

Robert Hooke discovered cells under a microscope in 1665. He took a sliver of cork and called the small encasements he saw, cells. They were dead cells, though.

The first person to see living cells, was a man named Anton van Leeuwenhoek. He took pond water and observed that under a microscope.
