what tools arte generally used for rocket science

Nikola Tesla was born in Smiljan, which is now part of Croatia. He spent much of his life living and working in the United States, particularly in cities like New York and Colorado Springs. Tesla also had residences in Paris and Prague during different periods of his life.

Niels Bohr conducted various experiments related to the atomic structure of elements, including the hydrogen atom. His most famous experiment was the Bohr model of the atom, which proposed that electrons orbit the nucleus in fixed energy levels. This model revolutionized the understanding of atomic physics in the early 20th century.

Linus Pauling worked at the California Institute of Technology (Caltech) for much of his career. He was a prominent chemist and had a significant impact in the fields of chemistry and peace activism.

Well I'll just use two points from the cell theory:

1) The cell is the basic unit of structure and function in all living things.

In the late 1800s, a scientist named Schwann told the world that he observed cells in animals. A short time later, another scientist named Schleiden said the same for plants. This was a huge start to the cell theory.

2) All cells rise from pre-existing cells. It's hard to believe but at one point actual scientists believed that living things could come from inorganic matter. It was not until Louis Pasteur's experiment with the S-shaped flask, and the boiled water, that people started to shun the thought of spontaneous generation and look at this final addition to the cell theory.

It my basic idea that Tesla was a Mentor to everyone in this world. Electricity is useless if it can't do anything, so in 1890, Tesla invented a motor to run on AC, the same type of motor used in every household appliance today. Scientists of the late 1880's were convinced that no motor could work with AC. After all, AC electricity reverses itself 60 times a second, so all previous motors would just rock back and forth 60 times a second. Tesla solved this problem and proved them all wrong.

Tesla developed and used florescent bulbs in his lab some 40 years before industry "invented" them. At the World's Fair, Tesla took glass tubes and bent them into famous scientists' names- the first neon signs. Tesla also designed the world's first hydroelectric plant at Niagara Falls in 1895. Tesla also patented the first speedometer for cars in 1916.

Tesla is most famous for conceiving the rotating magnetic field principle (1882) and then using it to invent the induction motor together with the accompanying alternating current long-distance electrical transmission system (1888). His patents and theoretical work still form the basis for modern alternating current electric power systems. He also developed numerous other electrical and mechanical devices including the fundamental principles and machinery of wireless technology, including the high frequency alternator, the "AND" logic gate and the Tesla coil, as well as other devices such as the bladeless turbine, the spark plug and numerous other inventions.

1. Dr. William A. Graham - a leading Caribbean scientist known for his work in environmental science and sustainable agriculture.
2. Dr. Michelle Emmanuel - a prominent Caribbean biologist specializing in marine ecology and conservation.
3. Dr. Terrence Forrester - a renowned Caribbean physiologist recognized for his research on nutrition and chronic diseases.

Nikola Tesla and Thomas Edison were opponents in The Battle of the Currents, the rivalry between Tesla's alternating current (AC) system for electricity and Edison's direct current (DC) system for electricity. AC 'won' the battle, the current is far more effective. This means that all electricity used today travels by AC, not DC. All DC is used for anymore is batteries.

John Dee was born in 1527 and was an astronomer and a mathematician as well as an astrologer and an occultist. His greatest contribution to science was in the field of navigation, where he pioneered some of the star navigation techniques that were used by sailors for many years.

Foreign Scientists: You don't say which country you're in, so I can't say who is foreign to you. But here are some examples of scientists from around the world:

William Perkin- A British chemist, he invented the first synthetic dye, mauveine. Herman Mark- the father of polymer chemistry, was an Austrian Jew. I like Otto Bayer a lot. He was a German, and he invented polyurethane. He's not related to the Bayer family that started the chemical company he worked for. Otto Rohm and Otto Haas were Germans who invented acrylate polymers. These are used for things like Plexiglas and the plastic layer of safety glass. Leo Baekeland was a Belgian who invented two things: prepackaged photo paper and phenolic plastic. The photo paper made him rich; the phenolic made him immortal.

The different types of scientific investigations include descriptive studies, experimental studies, observational studies, and theoretical studies. Descriptive studies aim to describe a phenomenon, experimental studies involve manipulating variables to test hypotheses, observational studies involve observing and analyzing data without intervening, and theoretical studies involve developing and testing models or theories.

Satyendra Nath Bose and Albert Einstein made important contributions to the development of quantum mechanics through their collaboration on the theory of photon gas. This work led to the discovery of Bose-Einstein Condensate.

Tesla died of heart failure alone in room 3327 of the New Yorker Hotel, on 7 January 1943.

Scientists use a hierarchical system called taxonomy to classify living things. Organisms are grouped based on shared characteristics into categories such as kingdom, phylum, class, order, family, genus, and species. The classification is based on similarities in physical traits, genetics, and evolutionary relationships.

Louis Pasteur discovered the principles of vaccination, pasteurization, and germ theory of disease. His work in microbiology revolutionized our understanding of how diseases are caused and how they can be prevented. His discoveries have had a lasting impact on medicine and public health.

most of his child hood was spent in a small tome in Europe ....when he was in his late 20's he came here to the states and becme a citezen ....he had a lab in NJ for some time and went fromt there to Niagra falls NY and Buffalo NY in 1898-1903 ruffly he was here in Bufflo for the worlds fair in 1901 and using his AC current and a new kind of Bulb (long story) he lite up Buffalo NY for the fair he stayed here fro some time working with Westinghouse as a money backer (Westionghouse office stood where the airport is today) and he had a room where he got his 3 hours of daily sleep he made a power plant at the foot of Niagra falls and was running till the late 50 and it fell into the gorge at the bottom of the falls soo there after....he then moved to Colorado and tryed a few experaments that didn't work like he had hoped (He burned out the bolder dam power station) the whole station ....... so after he gave Westionhouse an Idea to send power through the air with out wired ....they thought this was a great Idea (no more downed power lines and no more wires to fix) till they asked him how they would charge for this wireless power ....Tesla said ...no it for free!!! they labled him nuts and fired him ...he died soo after a broke man .....ain't larger companys great???

Isaac Newton is a famous scientist who studied forces. He formulated the laws of motion, including the law of universal gravitation, which describe the relationship between an object and the forces acting upon it.

Known as the founder of microbiology, Pasteur discovered the role of bacteria in fermentation. His experiments with bacteria conclusively disproved the theory of spontaneous generation and led to the theory that infection is caused by germs. Extrapolating from this knowledge, Pasteur then developed a process in which liquids such as milk were heated to kill all bacteria and moulds already present within them. This process became known as pasteurisation.

Tesla completed his elementary education in Croatia. He continued his schooling in the Polytechnic School in Graz and finished at University of Prague. He worked as an electrical engineer in Germany, Hungary and France before emigrating to the United States in 1884.

Robert Koch was motivated to study diseases by his desire to find ways to prevent and treat infections that were causing widespread illness and death. He was particularly fascinated by the idea of identifying the specific causes of diseases, which led to his groundbreaking work in establishing the germ theory of disease. Koch's studies were ultimately driven by his commitment to improving public health and saving lives.

Scientists divide the elements on the periodic table into metals and non-metals, with a subcategory of transition metals in between. Gasses are on the right of the periodic table, while metals are on the left.
