The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913. Many concidered the Tesla Turbine an Engine of the 21st Century. Nikola Tesla created an engine design nearly 100 years ago that is as much as three or four times more efficient than the combustion engine design that has dominated for reasons other than science.

At the time of his invention around 1909, Tesla was able to demonstrate a fuel efficiency of 60% with his bladeless turbine design. The most efficient combustion engines today do not get above 27 - 28% efficiency in their conversion of fuel to work. The politics of his day impeded Tesla's design from being implemented. The piston engine was already well under way, and the oil barons were not encouraging efficiency. Still today, engine manufacturers resist any changes because of retooling expenses.

They don't look exactly the same. Each person is different. They all look different but what's common with the scientists or doctors are they have white lab coats and glasses.

Firstly, since which civil war?

Secondly, scientists have made millions of contributions since most of them. They include huge advances in astronomy, nuclear physics (almost anything involving it, in fact), chemistry (the isolation and study of many compounds, identification of chemical structures, new elements discovered or created), biology (medicine in particular), economics (so much more advanced), mathematics.. virtually anything you can think has been largely contributed to since then.

Christian Pesigan is a filipino chemist.

He was close to finding how to provide free electricity but died before it could be announced. Some believe he was murdered by workers sent bu the US government and all his research was collected and taken away by them.

He was older than his sisters and the older brother died from a horse accident making him the older kid.

1. He or she states the problem
2. The scientist forms a hypothesis, a possible solution to the problem. The simplest solution is often the best solution.
3. Next, a scientist might want to perform a controlled experiment. A controlled experiment can give a scientist more information about his or hers hypothesis.
4. Results are recorded and analyzed.
5. Using the data the scientist can develop a conclusion.

Some of Tesla's patents are not accounted for, and various sources have discovered some that have lain hidden in patent archives. There are a minimum of 278 patents issued to Tesla in 26 countries that have been accounted for.

Also referred to as an organic growth strategy, it's a strategy focused on making the core business better. i.e. Developing new products, increasing efficiency, hiring the right people, better marketing etc. On the other hand, an external growth strategy is more concerned with M&As, JVs, strategic alliances, etc.

Nikola Tesla invented the Tesla coil as part of his research on wireless transmission of electrical energy. He developed the coil to experiment with high-frequency alternating currents and wireless power transmission. The Tesla coil allowed him to study electrical resonance and create high-voltage, high-frequency electricity.

he allowed math to go further than anyone else did

Edward Jenner died on January 26, 1823 at the age of 73.

To bad those are all contributions to physics, not mathematics.

Anton van Leeuwenhoek, at age 16, first saw cloth through a microscope.

He was an apprentice to a merchant who sold cloth and the merchants used microscopes to inspect the threading and weave.

Six years later, he acquired a shop of his own and, of course, a microscope of his own for the purpose of looking at cloth. At some point, his interests went beyond his business and he learned to polish glass and make his own lenses. About 1670 he discovered a way to make very small spherical lenses. This allowed much greater magnification, up to 250 times. (Some people think that he evnetually made lenses with magnifications almost twice that.)

After discovering the technique (which he kept secret) he saw many fantastic things, including microorganisms in water.

The first thing he officially described in a letter to the Royal Society of London were his observations and drawings of the parts of a bee.

Later, he described microorganisms in water.

She was the doctor who discovered a way to detect sickle cell anemia.

Angella D. Ferguson is an African-American doctor born in 1925. Her father was a teacher at an elementary school in Washington, DC. She was born with sickle cell anemia. She was inspired to become a doctor and studied the disease for over 20 years, discovering ways to prevent critical illness for those with sickle cell and other genetic defects. She retired after 42 years in medicine, more than half of that time in pediatrics.

Jean-Baptiste Quentin was a French musician and classical composer. He was born some time in 1695 and died in 1750. Quentin played both the violin and the viola.

The unit of force, the newton, is named after Sir Isaac Newton, a famous physicist and mathematician known for his groundbreaking work in classical mechanics and gravity.
