Surrounding unrepeated words, Alpha and Beta tangent their reasons. They should both in their lives Be dry in opinion. As Gamma arises, a new situation is triangulated: The difference becomes a drama And the sum a great confusion. The hypotenuse generated by them loomed by the distortion. Would that Pythagoras and Tales unite them for the same reason.
In the area of measurement, we say that scale is the constant ratio between any physical or chemical quantity that allows a comparison. In the case of a drawing or map, we call the cartographic scale the mathematical relationship between the dimensions presented in the drawing and the real object it represents. These dimensions should always be taken in the same unit.
Did you know that dermatologists have come up with a formula to roughly calculate a person's body surface area? The area (in m 2) is calculated as a function of the individual's mass (m): For example, a person with a mass of 70kg has a body surface area of approximately: The resulting value is useful for determining the amount of heat. lost through sweat.
A year is leap when it is divisible by 4. But there is one exception. Years ending with two zeros will be leap if they are divisible by 400. Example: 2012 is a leap year. For 2012/4 = 503, that is, an exact division. 1998 is not a leap year, because 1998/4 = 499.5, an inaccurate division.
A number is capitalized when read from left to right or right-to-left always represents the same value, such as 77, 434, 6446, 82328. To get one number from another, the order of the numbers is reversed. digits and sum with the given number a number of times until a capicua number is found, for example: From the number 84: 84 + 48 = 132; 132 + 231 = 363, which is a capicua number.
Easter 2008 happened very early on March 23rd. In fact, it was earlier than any of us will see during our lives! The last time this happened was in 1913. The next time Easter will take place on March 23, will be in the year 2228. Therefore, we will not be here to witness (at least in this life, for those who thought of reincarnation).
The largest number accepted in the system of successive powers of ten is the million, first recorded in 1852. It represents the hundredth power of one million, or the number 1 followed by 600 zeros (although only used in Great Britain and Germany). ).

Did you know that there was a mathematical Pope? Gerbert, famous geometer, was archbishop of Ravenna and ascended to St. Peter's Chair in the year 999. Considered one of the wisest of his time, he was called Pope Silvester II. It was the first to vulgarize in the Latin West the use of Arabic numerals. In addition to mathematics, he devoted himself to the study of astronomy, physics as well as other sciences under Muslim rule in Spain.
Tales of Miletus - asphyxiated by the crowd when leaving a show. Archimedes - murdered by a Roman soldier. Eratosthenes - killed himself, starving himself. Hypatia - cut by a group of exalted people during a mutiny in Alexandria. Évariste Galois - killed in a duel. Pythagoras - assassinated in Tarento during a revolution.

The secret: the number cannot be repeated in the same column, row or block. Here's an example of Sudoku, with its solution: Solution: Click here to download Sudoku Solver, a puzzle solver software.
Several films have Mathematics as their theme. Here are some of them: Breaking the Bank ”(USA, 2008), by Robert Luketic. "The Proof" (USA, 2005), by John Madden. "A Bright Mind" (USA, 2005), by Ron Howard. “Enigma” (USA, 2001), by Michael Apted. “Pi” (USA, 1988), by Darren Aronofsky.
The inverse operations of potentiation are: root and logarithmization. This is because in the potentiation operation there is no commutativity property. For example: 5 3 = 5 x 5 x 5 = 125 is different from 3 5 = 3 x 3 x 3 x 3 x 3 = 243 By definition, the inverse operation to potentiation consists of: given the power and one of the data, the base or exponent must determine the other.
Satellite dishes have the shape of a curve called a parabola, which is associated with the graph of second degree function. We define parable from a line r and a point F, called focus, in a plane. The focus parable F and guideline r is the set of all points whose distance to the line r is equal to the distance to the point F.
The differential and integral calculus, which Newton develops at the same time as the German Wilheim Leibniz (1646-1716), revolutionizes mathematics. To know the area of a circle using the new tool, just divide that circle into even, small squares. Then the area of a square is calculated and multiplied by the total number of squares.
The damn tomatoes Difficulty level: You have a 2-plate scale and 12 tomatoes, with: - 11 having the same weight - 1 having the different weight (we don't know if it's lighter or heavier) With only three weighings, find out which tomato is different and whether it is lighter or heavier. * challenge sent by user Fábio Gomes Cordeiro.
Just over 150 years ago, the matrices had their importance detected and emerged from the shadow of the determinants. The first to give them a name seems to have been Cauchy, 1826: tableau (= table). The parent name only came with James Joseph Sylvester, 1850. His friend Cayley, with his famous 1858 Memoir on the Theory of Matrices, spread the name and began to demonstrate its usefulness.
Fire in the Rope Difficulty Level: We have two ropes that do not necessarily have the same length. If we set fire to the end of either string, it will take exactly 1 hour for the fire to reach the other end of the string. However, the fire will not move at constant speed, it may be faster at some points and slower at others.
