Rene Descartes was an inventor but far from that he was a philosopher. He devised the theory Cogito Ergo Sum which translates from Latin into English as I think, therefore I am. This statement which he himself conjured up and is his most notable achievement has been designated to proving certainty. Descartes believes that through skepticism certainty can be produced. He states that nothing in the universe can be proven beyond doubt; however he also states that doubt is none other than thought and that thought is none other than the mind. SO therefore the only thing that can be proven beyond doubt is the mind. Along with this he came up with the notion that if we as imperfect beings were created by some outside force, then that outside force has to be designed as a perfect entity. Thus it was the perfectibility of an outside force-namely God- that placed this imperfect knowledge within us. He is considered the father of modern philosophy mainly because he was the first individual who indicated that certainty exists in our world. He contributed in the area of optics as well as physics. He created the Cartesian coordinate system(which is still in use today); he founded analytical geometry alongside a colleague of his. He was one of the earliest dualists, indivudals who believed mind was separate from matter. He influenced future scholars and philosophers such as Kant, Locke, and Hobbes. Overall he was an overachiever, a brilliant mind, who brought many things to the world during the time of the enlightenment.
René Descartes was a French philosopher, mathematician, and writer who spent most of his adult life in the Dutch Republic. He has been dubbed the 'Father of Modern Philosophy', and much subsequent Western philosophy is a response to his writings, which are studied closely to this day. In particular, his Meditations on First Philosophy continues to be a standard text at most university philosophy departments. Descartes' influence in mathematics is equally apparent; the Cartesian coordinate system - allowing algebraic equations to be expressed as geometric shapes, in a 2D coordinate system - was named after him. He is credited as the father of analytical geometry, the bridge between algebra and geometry, crucial to the discovery of infinitesimal calculus and analysis. Descartes was also one of the key figures in the Scientific Revolution.

Planck's constant describes the ratio between the energy of an electromagnetic wave and the frequency of that wave.

There are several:
1. Humanistic Psychology which rejects the idea that clinical psychology and other applied areas should focus only on disorders and problems.

2. Cognitive Development emphasizes the idea that children are not incompetent adults but think creatively and effectively based on their limited experience in the world.

3. Behavioralism which says that psychologists should limit their attention to the study of behavior itself.

4. Psychodynamic Psychology that focuses on the role of our unconscious thoughts, feelings,
and memories and our early childhood experiences in determining behavior.

5. Functionalism was inspired by Darwin's work in biology and attempted to explain behavior,
emotion, and thought as active adaptations to environmental pressures.

6. Structuralism which uses the method of introspection.

Phoebe and David initially break-up due to David moving to Minsk in The One with the Monkey.

Then, in The One in Barbados, Phoebe and David break-up due to Monica and Chandler's 'meddling'. David was going to propose to Phoebe, due to some bad advice given by Chandler. Monica called Mike (Phoebe's eventual husband and ex-boyfriend at the time), telling him of David's plan. Mike flew to Barbados, proposed to Phoebe, and although Phoebe said 'no' to Mike, she broke up with David to get back with Mike.

yes he did

Inherited traits.

Luck was a factor because, at the time a beer companies beer was going off, so they decided to ask Pasteur for help. He then found that germs were the cause of the beer going bad. so therefore luck was most certainly a factor.

he was born a natural skeptic.

I think that anybody who wants 2 be a scientist or provide a service 4 his society in general must do some small things:1- try 2 improve his mind by solving IQ tests 2- be excellent @ his career as hard as possible & ask in each big or small thing about it in order 2 introduce new thing which may serve his society 3- be honest with his people so God leads him 2 the safe & good way. 4- read in all knowledge branches sincs the book is a gift which you can open again and again . MY best wishes 4 member @ Answers.com in the end.

Dr. Colin Hudson
Dr. Colin Hudson was a British-born Barbadian environmentalist and innovative scientist, acknowledged internationally as a key developer of the modern sugar cane harvester.

The plantation system was first developed by Portuguese explorers in West Africa.

One very important way that information is compared in the evolutionary history of a species is to use DNA. By checking how much is the same between species, we can see if those species are closely related or not. Our own DNA and that of the great apes are only different in about 1-2%.

The scientist that made highly accurate measurements that first disapproved the theories of Ptolmy and Copernicus was called Brahe.

TENS Unit is almost risk-free from harm, there is no side effects or addiction. The low-volt electrical current carried by the electrodes only penetrates the skin to the level of the nerve fibers, typically only one to two inches.

The Bohr model does not work at all for atoms having more than one electron because it does not account for interactions between the electrons.

Rutherford discovered that the atom has a nucleus, bohr's discovery is found on the Wikipedia Link further down this page.

Few question and answers on Bohr's atomic model

The basic assumption in Bohr's model of an atom is that
The energy of electron is quantised
In Bohr's model of the hydrogen atom
the radius of the nth orbit is propotional to n² the angular momentum of the electron in an orbit is an integral multiple of h/2λ the magnitude of potential energy of the electron in any orbit is greater than its K.E.

John Dalton did not have experimental evidence to support his theory of the atom when he proposed it in the early 19th century. His atomic theory was based on observational patterns rather than direct experimental data.

Well, yes! They have been doing it for centuries. For example, in Boston there was a mill dam built along what is now Causeway Street and used for turning paddlewheels. The tide came in and the wheels turned in one direction as the water poured into the lagoon; the tide went out and the wheels turned the other way as the lagoon emptied.

born in April 1933 in Kagoshima Prefecture, Japan. He graduated from the prestigious Tokyo University with a degree in economics, married, and had three children. In 1957 Hamada went to work for Ricoh Company

Scientist organize life forms by how they look and what they are.

The wax thought experiment is intended to illustrate how things maintain their initial identity though they do change form (ex. the essence of wax stays the same, though it changes state from solid to liquid as it burns).

I think he married his cousin.

It indicated that Jupiter is the fourth brightest object in the sky (after the Sun, the Moon and Venus).
