Math Rooms

Most rooms in Lester B. Pearson High school bear the name of a person who has contributed to the evolution of our societies. We have rooms named after scientist, poets, politicians and, of course, famous mathematicians.

Math Central
Math Central is one of the largest room at Pearson. It can accommodate two classes at the same time and we have about 24 computers available for students' use. All other math rooms are located around (or close to) Math Central.

To learn more about the other math class rooms and the individuals they are linked after please click on of the following links.

Descartes | Euclid | Gauss | Leibniz | Pascal | Pythagoras


Descartes (1596-1650)

DescartRené Descartes is probably most famous for the following quote : "Cogito ergo sum", or for those of us who have not taken Latin in school: "I think therefore I am". Descartes was the founder of Analytical Geometry and originated the Cartesian Plan, which is taught extensively in Math 10 and Math 13. He also contributed to science, with works on optics, physiology and psychology. Like his compatriot Pascal, Descartes also wrote many important books (Discourse on the Method in 1637 and Meditations in 1641) that contain his philosophical theories.

Euclid (365 - 300 BC)

EuclidUp until recently, Euclidian geometry was one of the main focus of the teaching of mathematics (along with arithmetic and algebra). Almost every geometry textbook was then based on a treatise called The Elements, written more than 2000 years ago by Euclid of Alexandria (Egypt), by far the most important mathematician of antiquity. This book compiled all the mathematical knowledge of the time and stressed the use of a deductive system of proofs. Euclid's ideas and theorems are still present today in the teaching of geometry at various levels, like in Math 13 for instance. Over a thousand editions of The Elements have been published since the first printed version of 1482, making it the best-selling math textbook of all time!

Gauss (1777-1855)

GaussJohann Carl Friedrich Gauss is one of the most famous mathematicians of all time. His contributions to the field of mathematics, physics and astronomy have secured him a place in history. He proved his genius very early on: at age 7, he figured out an ingenious and simple way of adding all the numbers from 1 to 100. Later in life, he discovered the binomial theorem which is one of the topics studied in Math 30. He made other contributions to math, especially in the field of number theory and geometry.

Leibniz (1646-1716)

LeibnizBaron Gottfried Wilhelm von Leibniz was a German philosopher and mathematician. A precocious youth, Leibniz taught himself Latin and some Greek by age 12 so that he might read the books in his father's library. Leibniz studied Law and he chose to to pursue the active life of a courtier. In 1672, he was sent to Paris to try to dissuade Louis XIV from attacking German areas. During his trip to France, which lasted 4 years, he studied mathematics and physics under Christian Huygens. It was Huygens that inspired Leibniz to work on what became known today as Calculus (the mains topic of Math 31). Leibniz invented Calculus concurrently but independently of another famous scientist of the 17th century, sir Isaac Newton.

In 1675, Leibniz wrote a manuscript in which he used the notation Integralfor the first time. Nowadays, this notation is used by everyone who does calculus. In 1700, Leibniz founded the Berlin Academy and was its first president.

Pascal (1623-1662)

PascalBlaise Pascal was not only a prodigious mathematician, but also made remarkable contributions to science, philosophy and literature. Two of his best known books, Les Lettres de Provinces et Les Pensées, are all widely read to this day. Pascal also invented one of the earliest mechanical adding machine, la Pascaline. In mathematics, he is considered to be the founder of the modern theory of Probability, where his famous triangle (Pascal's Triangle) is still commonly used today.

Pythagoras (582-507 BC)

PythagPythagoras of Samos was a Greek philosopher whose teaching influenced not only mathematics, but also astronomy and the theory of music. He founded a school in Croton (in Southern Italy) around 532 BC. One of the guiding principle of Pythagoras' school was that all things and relationships could be expressed using numbers. For example, musical notes are generated by using certain ratios on a stringed instrument. The Pythagorean Theorem is also attributed to Pythagoras. This theorem states that, in a right triangle, the sum of the squares of the two legs is equal to the square of the hypotenuse. Although this theorem has been know for more than 1000 years, he is thought to be the first one to ever prove it. Another great discovery and ingenious proof attributed to Pythagoras has to do with the existence of irrational numbers (like Square Rootfor instance).
