Cool Math 4 Kids Times Tables Help - How Multiplying Works (times tables) Here's another one: This means that you have three groups of 5! Put the three groupstogether... How many pentagons do you have? Count them... So, our answer is: Let's switch the numbers around and do it the different way! This means that you have five groups of 3! Put the five groupstogether... Count them... Hasse diagram Hasse diagrams are named after Helmut Hasse (1898–1979); according to Birkhoff (1948), they are so-called because of the effective use Hasse made of them. However, Hasse was not the first to use these diagrams; they appear, e.g., in Vogt (1895). Although Hasse diagrams were originally devised as a technique for making drawings of partially ordered sets by hand, they have more recently been created automatically using graph drawing techniques.[1] The phrase "Hasse diagram" may also refer to the transitive reduction as an abstract directed acyclic graph, independently of any drawing of that graph, but this usage is eschewed here. A "good" Hasse diagram[edit] Although Hasse diagrams are simple as well as intuitive tools for dealing with finite posets, it turns out to be rather difficult to draw "good" diagrams. The following example demonstrates the issue. . Upward planarity[edit] Notes[edit] References[edit] External links[edit] Related media at Wikimedia Commons:
Benford's law The distribution of first digits, according to Benford's law. Each bar represents a digit, and the height of the bar is the percentage of numbers that start with that digit. Frequency of first significant digit of physical constants plotted against Benford's law Benford's law, also called the first-digit law, is a phenomenological law about the frequency distribution of leading digits in many (but not all) real-life sets of numerical data. It has been shown that this result applies to a wide variety of data sets, including electricity bills, street addresses, stock prices, population numbers, death rates, lengths of rivers, physical and mathematical constants,[3] and processes described by power laws (which are very common in nature). The graph here shows Benford's law for base 10. It is named after physicist Frank Benford, who stated it in 1938,[4] although it had been previously stated by Simon Newcomb in 1881.[5] Mathematical statement[edit] Example[edit] History[edit] Explanations[edit]
Chaos theory A double rod pendulum animation showing chaotic behavior. Starting the pendulum from a slightly different initial condition would result in a completely different trajectory. The double rod pendulum is one of the simplest dynamical systems that has chaotic solutions. Chaos: When the present determines the future, but the approximate present does not approximately determine the future. Chaotic behavior can be observed in many natural systems, such as weather and climate.[6][7] This behavior can be studied through analysis of a chaotic mathematical model, or through analytical techniques such as recurrence plots and Poincaré maps. Introduction[edit] Chaos theory concerns deterministic systems whose behavior can in principle be predicted. Chaotic dynamics[edit] The map defined by x → 4 x (1 – x) and y → x + y mod 1 displays sensitivity to initial conditions. In common usage, "chaos" means "a state of disorder".[9] However, in chaos theory, the term is defined more precisely. where , and , is: .
Boulanger: la saga continue (2/2) PART 2 Les mystères du monde continu Je vous ai montré dans le billet précédent pourquoi en mélangeant de façon très méthodique une image faite de pixels (j’étale dans un sens, je replie et je recommence) on revient tôt ou tard à la l’image initiale. Mais aujourd’hui nous allons voir que cet éternel recommencement est un privilège réservé aux images numériques. Pétrissage décimalPour vous le montrer simplement, je vais modifier légèrement la méthode de pétrissage: le boulanger étire son carré de 10 fois sa longueur initiale (au lieu de deux) et il coupe les neuf morceaux qui dépassent afin de retrouver la forme initiale du carré une fois empilés. C’est un peu plus compliqué à première vue mais vous allez vite comprendre pourquoi ça simplifie les calculs… Supposons que notre carré ait une longueur 1 de côté et divisons le verticalement en 10 bandes de largeur 0,1 chacune. La transformation consiste donc à simplement déplacer la séparation entre abscisse (écrite à l’envers) et ordonnée.
