Scientists

Not lately. He hasn't published anything in quite a while. But there are some rumors going around,

repeated by some very reliable experts in the field, that Rene is working on a major manuscript, and

that when he releases it, it'll really shake up a lot of the foundations of math. We should be ready.

Rene Descartes was born in the town of Haye en Touraine, France.
After his death Haye en Touraine was renamed Descartes in his honour.
Ville Descartes is in the Indre-et-Liore region of France (southwest of Paris)

Rene Descartes was a philosopher, mathematician and scientist. He made several discoveries and unfortunately, your question does not specify which discovery you are referring to.

I believe she was called "Auntie Perni."

Yes, he did. He devised the Cartesian coordinate system which led to analytical geometry.

Rene Descartes was a French mathematician and in the early 17th century he introduced what we call today the Cartesian coordinate plane in which graphs are plotted.

Rene Descartes is regarded as the father of Western philosophy. His writings influence most of the subsequent writings in Western philosophy.

Descartes explains the logic behind the laws of reflection he discovered in his work "Dioptrics". He uses the idea of a tennis ball bouncing at an angle of the ground and up through a sheet to formulate the laws of reflection on a geometric plane.

He thought about philosophy and science.

Descartes used the parabola to illustrate algebraic equations. He put these equations on a visible plane using the Cartesian coordinate system and they sometimes took the shape of a "u" curve, or a parabola.

Rene Descartes initiated the process in which algebra is thought upon. His major contribution was making me have to do this pointless essay.

The wording of this question implies that you already know of some subjects in which Descartes contributed, and want to know what else he did. However, we have no way of knowing what you know and so cannot answer the question.

he's work for a teacher

His main philosophical contribution was "cogito ergo sum" which translates to "I think therefore I am".

He is the "father of modern philosophy". Together, he and Francis developed the scientific method.

Of course he did. He was a rational human being.

he actually didn't discover it

Descartes had one daughter.

Remember that a hypothesis is a 'good' guess about a question. If a scientist comes up with a hypothesis, she will test it and then see if the testing will say 'yes'. She will then do these many times and if the answer still is 'yes' she will have it published. Many others in the same field will then review that data and they will add to the information or they may not agree.

Descartes didn't really 'discover' things. He was a philosopher and mathematician. He is known, amongst other things, for developing the cartesian system of co-ordinates (the xy system we usually use for graphs), founding rationalist philosophy, for his work on optics, and for laying the mathematical foundations for the development of the calculus.

He was considered the father of Western philosophy: much of Western philosophy written since his time was influenced by his writings.

Gomene, I am also searching for the answer so I thought that the answer would be here and I didn't actually think I am the one who will suppose to answer this

The phrase "facts are facts but perception is reality" is often attributed to Lee Atwater, a prominent American political consultant. Atwater was known for his strategic approach to shaping public perception and understanding the importance of how information is perceived. This quote highlights the idea that while objective facts may exist, individuals' interpretations and beliefs ultimately shape their reality.
