Feel free to talk about your favorite Scientist or Scientists if you have more then 1 that you really like :) a few of my favorite Scientists are
Albert Einstein (1879-1955) Sir Isaac Newton (1643-1727)James Clerk Maxwell (1831-1879):)

Albert Einstein (1879-1955)
Einstein is probably the most famous scientist of all time. He burst on the scene in 1905 when he managed to solve three of the outstanding problems of physics: photoelectric effect, Brownian motion, and special theory of relativity. These three publications have become known as the "Einstein trilogy."
Einstein's greatest work occurred in 1915 when at the "advanced age" of 36, he published the general theory of relativity showing that gravity and acceleration are the same.

Sir Isaac Newton (1643-1727)
There can be no outstanding scientist list without Sir Isaac Newton; he made revolutionary advances in mathematics, optics, physics, and astronomy. In 1687 Newton published the Philosophiae naturalis principia mathematica. Principia, as it has become known, is recognized as the greatest scientific book ever written! Newton analyzed motion of bodies under the action of centripetal forces. The results were applied to orbiting bodies, projectiles, pendulums, and free-fall near the Earth. He further demonstrated planets were attracted toward the Sun by a force varying as the inverse square of the distance and generalized that all heavenly bodies mutually attract one another. In order to perform his calculations, Newton invented calculus.
Newton also explained a wide range of previously unrelated phenomena such as eccentric orbits of comets, tides and their variation, precession of the Earth's axis, and motion of Moon as perturbed by gravity of Sun. Newton was deeply interested in light and published optics in 1704. Although he believed a wave theory more probable, he relied on a corpuscular theory to account for phenomena such as reflexion, refraction, colors, and diffraction.

Newton's Three Laws of Motion:
1. A body continues in a state of rest, or motion with a constant velocity, unless compelled to change by an unbalanced force.
2. The acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass.
3. For every action force, there is an equal and opposite reaction force.

James Clerk Maxwell (1831-1879)
Maxwell is considered the scientist of the 19th century who had the greatest influence on 20th century physics. In 1931 Einstein described Maxwell's work as "the most profound and the most fruitful that physics has experienced since the time of Newton." Maxwell calculated the speed of propagation of an electromagnetic field as approximately that of the speed of light. He proposed the phenomenon of light is an electromagnetic phenomenon. In 1873 Maxwell published his Treatise on Electricity and Magnetism which contains his famous Maxwell equations; the four partial differential equations are one of the great achievements of 19th-century mathematics.
Maxwell also formulated, independently of Ludwig Boltzmann, the Maxwell-Boltzmann kinetic theory of gases. This theory showed that molecules at high temperature have only a high probability of moving toward those at low temperature. Maxwell's approach did not reject the earlier studies of thermodynamics but used a better theory of the basis to explain the observations and experiments.another great 1:)

Nikola Tesla
Inventor, 1856 - 1943

David Joseph Bohm

(20 December 1917 – 27 October 1992) was an American-born British quantum physicist who contributed to theoretical physics, philosophy of mind, neuropsychology. David Bohm is widely considered to be one of the most significant theoretical physicists of the 20th century.

Why:
Implicate and explicate order

Implicate and explicate order according to David Bohm

At Birkbeck College, much of the work of Bohm and Basil Hiley expanded on the notion of implicate, explicate and generative orders proposed by Bohm.[10][11][12] In the view of Bohm and Hiley, “things, such as particles, objects, and indeed subjects” exist as “semi-autonomous quasi-local features” of an underlying activity. These features can be considered to be independent only up to a certain level of approximation in which certain criteria are fulfilled. In this picture, the classical limit for quantum phenomena, in terms of a condition that the action function is not much greater than Planck's constant, indicates one such criterion. They used the word holomovement for the activity in such orders.

And:

Holonomic brain theory

In a holographic reconstruction, each region of a photographic plate contains the whole image

In collaboration with Stanford neuroscientist Karl Pribram, Bohm was involved in the early development of the holonomic model of the functioning of the brain, a model for human cognition that is drastically different from conventionally accepted ideas.

Bohm worked with Pribram on the theory that the brain operates in a manner similar to a hologram, in accordance with quantum mathematical principles and the characteristics of wave patterns.

awesome there Jeanniebean :)

How about Nikkoli Tesla? He invented ahead of his time and pioneered many new concepts and thoughts?
