I believe he is a botanist.

Answer

Carolus Linnaeus

The 1735 publication of Systema naturae established the fame of Linnaeus with an organized classification structure for all living things. The binomial system of nomenclature, now the basis for naming and classifying all organisms, was first introduced by Linnaeus in 1749. In his Species plantarum in 1753 Linnaeus attempted to name and describe all known plants, calling each kind a species and assigning to each a two-part Greek or Latin name consisting of the genus (group) name followed by the species name. Many of his names of flowering plants survive with little if any change -- for example, Quercus Alba for white oak. The 1758 edition of Systema naturae extended binomial classification to animals.

Descartes is a famous and well noted European mathematician who lived hundreds of years ago. He pioneered many of the complex math procedures, equations, and mathematical formulas that we still use today.

Descartes is the namesake of the standard "Cartesian" or rectangular coordinate system.

He also is famous for saying "I think, therefore I am."

Descartes' theory provided the basis for the calculus of Newton and Leibniz, by applying infinitesimal calculus to the tangent line problem, thus permitting the evolution of that branch of modern mathematics. This appears even more astounding considering that the work was just intended as an example to his Discours de la méthode pour bien conduire sa raison, et chercher la verité dans les sciences (Discourse on the Method to Rightly Conduct the Reason and Search for the Truth in Sciences, better known under the shortened title, "Discours de la méthode").

Descartes' rule of signs is also a commonly used method in modern mathematics to determine possible quantities of positive and negative zeros of a function.

Descartes created analytic geometry, and discovered the law of conservation of momentum. He outlined his views on the universe in his Principles of Philosophy.

Descartes also made contributions to the field of optics. He showed by using geometric construction and the law of refraction (also known as Descartes' law) that the angular radius of a rainbow is 42 degrees (i.e. the angle subtended at the eye by the edge of the rainbow and the ray passing from the sun through the rainbow's centre is 42°). He also independently discovered the law of reflection, and his essay on optics was the first published mention of this law.

One of Descartes most enduring legacies was his development of Cartesian geometry, the algebraic system taught in schools today. He also created exponential notation, indicated by numbers written in what is now referred to as superscript.
