Mathematics is one of the most exact Sciences, without which modern man is difficult to imagine life. She is one of the main engines of progress, which perform complex calculations. Readers are the most interesting facts about math, and historical moments is closely related.
10. Hypatia was the first woman mathematician
Woman scientist Hypatia of Greek origin were among the fairer sex the first who began to study mathematics. It owns several works, which, as suggested by some modern scholars, were written by her in collaboration with his father – Theon of Alexandria. The most popular are the comments to the writings of prominent ancient mathematicians. From Hypatia was also a private school, where she taught philosophy in addition to mathematics and astronomy.
9. The emergence of a private language of mathematics
Interestingly, earlier mathematical proof was recorded verbally. This is evident in the work of Euclid "the Beginning". Records held in this way was not very convenient to use because of its excessive bulkiness. The founder of launching its own language of mathematics is considered to be the French mathematician françois Viet, who lived in the 16th century. He's one of the first to use alphabetic characters, which replaced the specific calculation. With the introduction of this innovation scientist with time all the words in the formulas got a replacement on special mathematical symbols.
8. The fact of the equal sign
The "=" sign first appeared in the 16th century. Its Creator is a Welsh physician and mathematician Robert Record. It was he who in 1557 was offered instead of verbal designations to use this mathematical symbol. The use of two parallel lines, symbolizing equality, he explained in simple words by saying that nothing can be more identical than these two lines. Prior to this innovation the equality marked by ("est egale"). However, the mathematical innovation of the spread at once. In the 17th century French mathematician Descartes used the symbol æ to denote the equality sign "=" used to specify the coefficient, which can be negative. Established symbol in science only in the early 18th century.
7. Facts about the number 7
Followers of the teachings of Pythagoras were attributed to the mathematical symbol of seven different properties. They considered seven as a model of harmony in nature and the divine order. The number contains two triads (threes), and the divine monad (one). The ancient philosophers and astronomers have considered 7 as a sum of two "real life" numbers 3 and 4. Under the number "3" they meant three people – a mother, father and child, and the "4" is the number of sides of the world. The number "3" and "4" to symbolize the triangle and the square, which in turn was considered a manifestation of perfection and completeness. For these reasons, seven had become was during the times of the Pythagorean sacred number.
6. The appearance of negative numbers in mathematics
Surprisingly, negative numbers appeared only in the 19th century. Earlier they did not use. For example, in Ancient Egypt, if the subtraction was negative roots of equations, they were rejected as impossible. However, was the exception to the rule, which was the ancient Greek mathematician Diophantus. It is believed that he is the only one who knew how already in the 3rd century to multiply negative values. From about the 7th century, negative numbers began to be applied in China and was interpreted as that of Diophantus as temporary values required to produce the final result. Visual geometric representation on the number line negative values received ten centuries. Full the theory of negative numbers was formed by William Hamilton and by Hermann Grassmann even two centuries later.
5. Mathematicians who are not awarded the Nobel prize
Interesting fact that mathematics can't get a Nobel prize. Such was the will of Alfred Nobel who decided to erase from the honorary list of this science. One version of why the inventor did so, is considered an intimate relationship with one of his beloved of mathematicians. So Nobel decided to "take revenge" all mathematical geniuses, throwing them from the list. Many modern scholars believe that this fact is nothing more than a tall tale, so the real reason is covered in a veil of secrecy.
4. Fact about mathematics George Danzig
The outstanding American mathematician George Dantsing, while still a student at the University, have solved a problem that couldn't figure out the most outstanding luminaries for many years. It so happened that one day George was late for class. Running into the classroom, he saw written on the Board the equation. The student decided that this is a homework assignment and wrote it down in a notebook. "Home" the task was given to the young man with difficulty, but still he decided. He later learned that the solved equation was considered unsolvable.
3. Calculation of own date of death Abraham de Mavrom
An eminent English mathematician, who was a disciple of Newton could with tremendous accuracy predict your date of death. Being older he noticed that every day the duration of sleep increases. The scientist made a mathematical calculation and figured out the date when you will be plunged into eternal sleep. This date was 27 November 1754 – then Abraham died.
Many of the well-known fact that many residents of East Asian countries are "afraid" of the number 4. The Chinese symbol for this number, pronounced as "death". For this reason, the inhabitants of Eastern countries expelled four of the numbering of houses, flats, floors, etc. mobile phone Numbers that contain this number are much cheaper, so superstitious Asian guy is unlikely to get into that room. It is known that in the name of the models of cell phones designed for the Asian countries is not used figure 4.
1. Facts about the number PI
Here for many years March 14, is the feast of the mathematical constant. Figure of the month and symbolize the number PI equal to ≈ 3,14. Also, this day is notable for the fact that on March 14, birthplace of the great mathematician Einstein. There is a so-called PI-clubs, in which not all mathematical scientists can get. To become a member, you must pass the appropriate exam for which you want memory to share as much as possible the number of digits of PI.
