Abu Abdullah Mohammed ben Musa Al-Khwarizmi was an Arab mathematician who was born around 780 and died around the year 850. Little is known about his life. There are indications that he or his family originated in Khowarezm, the region south of the Aral Sea, at the time part of Arab-occupied Persia (now part of Uzbekistan).
Polish mathematician and astronomer, author of the Heliocentric Theory, according to which the sun is the true center of the solar system, due to the succession of days and nights due to the rotation of the earth on its own axis. Copernicus was born in Tourun, Postnamia (Polish region on the banks of the Vistula) on the German border on 19/02/1453.
Julio César de Mello e Souza (pseudonym Malba Tahan), lived 79 years (from 1895 to 1974), mostly in Rio de Janeiro. Education: D. Pedro II College, RJ Normal School and RJ Polytechnic School (civil eng.). At the beginning of the century, it was quite difficult for national authors to publish anything: booksellers and newspaper owners were afraid of being hurt.
George Pólya was born on December 13, 1887 in Budapest (Hungary), a Jewish family of Polish origin. He died on September 7, 1985 in Palo Alto, California (United States). He was an excellent student in high school, although the school he attended highly valued memory-based learning, a practice that Pólya considered monotonous and useless.
One of the most original thinkers of the 14th century, Frenchman Nicole d'Oresme (1323-1382) was an economist, mathematician, physicist, astronomer, philosopher, psychologist, and musicologist. He also studied theology in Paris, later becoming chief financial officer of the University of Paris, then canon and finally Rouen's religious supervisor.
Michael Stifel, German mathematician, was born in 1486 and died in 1567. He has done research in arithmetic and algebra. He invented the logarithms independently of Napier, using entirely different approximations from those used by him. His best known work is Arithmetica integra, published in 1544.
Georg Friedrich Bernhard Riemann, was born on September 17, 1826, and died on July 20, 1866. He was one of the most influential 19th century German mathematicians. He developed the subjects of partial differential equations, complex variable theory, differential geometry, theory. of the analytical number and laid the foundations for modern topology.
Marie Sophie Germain is a typical illustration of the prejudice against female labor in the scientific circles of her time. Born in Paris, France on April 1, 1776, daughter of Marie Madelaine Gruguelin and Ambroise François a prosperous silk merchant. Determined to become mathematics, she read everything about it in her father's library, and in the books she was able to obtain, particularly works by Archimedes, Euler, and Newton.
Alexandre Théophile Vandermonde was born on February 28, 1735 in Paris, France, and died on January 1, 1796, also in Paris. His first love was music, and he turned to mathematics only when he was 35 years old. He was so close to Gaspard Monge that he became known as Monk's femme.
Knowing the number of people in a given location is important for the Government, as it will be able to plan policing, estimate the real need for professionals from different areas - doctors, nurses, firefighters, infrastructure, and even the number of glasses. water, ambulance and other benefits.
To accumulate that much money in just 30 days, you must do the following: - Save 1 cent on day 1 - Save 2 cents on day 2 - Save 4 cents on day 3 - Save 8 cents on day 4 - Save 16 cents on day 5 day… and so on, that is, the next day you should always have a total that is twice the previous day.
Willebrord Van Roijen Snell was a Dutch mathematician who was born in 1591 and died in 1626. He was the son of a mathematics professor at Leiden University. In 1613, his father succeeded in this role. Four years later, he created a method for determining distances by trigonometric triangulation.
Abraham de Moivre was born on May 26, 1667 in Vitry (near Paris), France, and died on November 27, 1754 in London, England. After spending five years in a Protestant academy in Sedan, Moivre studied logic in Saumur from 1682 until 1684. He then went to Paris, studying at the Collège de Harcourt, and taking private math classes with Ozanam.
In computing, when we refer to the size of a file or the storage capacity of some device, such as a thumb drive or the hard disk of a computer, we hear the terms byte, kilobyte, megabyte, gigabyte, among others less known. Each of these storage units is represented by a symbol: Byte - B Kilobyte - kB Megabyte - MB Gigabytes - GB In order to understand what each storage represents, you must first know what a bit is, which is the smallest unit. information that may be stored or transmitted.
The perfect square pairs: 144 and 441, 169 and 961, 14884 and 48841 and their respective roots: 12 and 21, 13 and 31, 122 and 221 are formed by the same digits, but written in reverse order. The mathematician Thébault has investigated the pairs that have this curious property. For example, you found the following pair: 1113 2 = 1.
Have you ever seen a 100 trillion dollar bill? If you think it doesn't exist, just look at the photo below. These dollars come from the Republic of Zimbabwe, an African country. But don't think you would get rich if you had such a note. On the contrary, maybe he couldn't even buy a bottle of water.
(1 + 2 + 3 + 4) 2 = 1 3 + 2 3 + 3 3 + 4 3 100 = 1 + 8 + 27 + 64 The square of the sum of a series of natural numbers starting with 1 is equal to the sum of the cube of your parcels. What are regular numbers? Index Next >> The fabulous # 142857
Wednesday, February 20, 2002 was a historic date. For a minute there was a conjunction of numbers that only occurs twice a millennium. This conjugation occurred exactly at 20 hours and 02 minutes of February 20 of the year 2002, ie 20:02 02/02 2002. It is a symmetry that in mathematics is called capicua (digits that give the same number when read from the left to the right, or vice versa).
There are several words derived from the word four. In addition to the numbers four hundred, four thousand, fortieth, among others, we can mention: Quad - four-sided polygon. Quadrant - arc corresponding to the fourth part of the circumference. Quadruped - which has four feet. Quartet - A piece of music performed by four voices or four instruments.
One yard is worth 91.44 centimeters or 0.9144 meters. King Henry I of England in the twelfth century fixed the yard as the distance between his nose and the thumb of his outstretched arm. It is currently the basic length unit in measurement systems used in the United States and the United Kingdom. The yard symbol is yd.
