Fibonacci number A tiling with squares whose side lengths are successive Fibonacci numbers In mathematics, the Fibonacci numbers or Fibonacci sequence are the numbers in the following integer sequence: or (often, in modern usage): (sequence A000045 in OEIS). The Fibonacci spiral: an approximation of the golden spiral created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling;[3] this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13, 21, and 34. By definition, the first two numbers in the Fibonacci sequence are either 1 and 1, or 0 and 1, depending on the chosen starting point of the sequence, and each subsequent number is the sum of the previous two.

8 Common Design Mistakes (and How to Avoid Them)   - The Shutterstock Blog What makes a design good or bad? True, it’s subjective to some degree — but ultimately, good graphic design will inspire responses and clearly communicate visual information. Bad design, on the other hand, will impede and muddle that communication. Human chemistry In chemistry, human chemistry is the study of reactions between people. [1] American self-defined 'human chemist' Thomas Dreier, gave the following definition of the subject of human chemistry, in 1948, considering people viewed atomically as human chemicals: [12] “Human chemistry, the study of how people ‘chemically’ react to one another, is an important branch of the science of human nature.” A central aspect in human chemistry is the definition of the person as a "human molecule", a term coined by French philosopher Jean Sales in 1789, being the atomic definition of a person. [4] In this perspective, human chemistry is the quantitative study of reactions between human molecules and the structures they form. This is expressed clearly by American historian Henry Adams who in 1885 gave the following definition of human chemistry (or rather 'social chemistry' as he called it): [24] A + B → AB (bond formation)AB → A + B (bond dissolution) Short history

Fibonacci Sequence The Fibonacci Sequence is the series of numbers: The next number is found by adding up the two numbers before it. The 2 is found by adding the two numbers before it (1+1) Similarly, the 3 is found by adding the two numbers before it (1+2), And the 5 is (2+3), and so on! Example: the next number in the sequence above is 21+34 = 55 the golden ratio turns famous faces into fibonacci celebrities jun 02, 2015 the golden ratio turns famous faces into fibonacci celebrities the golden ratio turns famous faces into fibonacci celebritiesimages courtesy of igor kkk in the seeming randomness of the natural world, instances of mathematical order are ubiquitous. the fibonacci numbers and similarly related ‘golden’ elements are evident in the composition of the galaxies, weather patterns and various types of lifeforms. these series of identically proportioned golden rectangles produce ‘perfect’ configurations, mathematically and aesthetically. the face of actor nicolas cage is disfigured into a rectangular shape based on the golden ratio

Fibonacci Leonardo Bonacci (c. 1170 – c. 1250)[2]—known as Fibonacci (Italian: [fiboˈnattʃi]), and also Leonardo of Pisa, Leonardo Pisano, Leonardo Pisano Bigollo, Leonardo Fibonacci—was an Italian mathematician, considered as "the most talented Western mathematician of the Middle Ages.".[3][4] Fibonacci introduced to Europe the Hindu–Arabic numeral system primarily through his composition in 1202 of Liber Abaci (Book of Calculation).[5] He also introduced to Europe the sequence of Fibonacci numbers (discovered earlier in India but not previously known in Europe), which he used as an example in Liber Abaci.[6] Life[edit] Fibonacci was born around 1170 to Guglielmo Bonacci, a wealthy Italian merchant and, by some accounts, the consul for Pisa. Guglielmo directed a trading post in Bugia, a port in the Almohad dynasty's sultanate in North Africa.

Fortunately for us all, there is no end to the number of weird and wonderful mysteries in the world, so we are now able to present our fourth list of unsolved mysteries. So – onwards to the world of the mysterious! Over the last few decades, miners in South Africa have been digging up mysterious metal spheres.

Pi Day: History of Pi Pi has been known for almost 4000 years—but even if we calculated the number of seconds in those 4000 years and calculated pi to that number of places, we would still only be approximating its actual value. Here’s a brief history of finding pi: The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for pi, which is a closer approximation. The Beauty of Mathematics: A Visual Demonstration of Math in Everyday Life This lovely video short from Yann Pineill and Nicolas Lefaucheux of Paris video production agency Parachutes succinctly demonstrates the underlying mathematics behind everyday occurrences in the format of a triptych. On the left we see the mathematical equation, in the middle a mathematical model, and on the right a video of such things as snowflakes, wind, sound, trees and magnetism. The video begins with the following quote: “Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, without the gorgeous trappings of painting or music.” —Bertrand Russell

The Fibonacci Numbers and Golden section in Nature - 1 This page has been split into TWO PARTS. This, the first, looks at the Fibonacci numbers and why they appear in various "family trees" and patterns of spirals of leaves and seeds. The second page then examines why the golden section is used by nature in some detail, including animations of growing plants. Let's look first at the Rabbit Puzzle that Fibonacci wrote about and then at two adaptations of it to make it more realistic. This introduces you to the Fibonacci Number series and the simple definition of the whole never-ending series. Fibonacci's Rabbits

Combining Fonts A palette with wit Use typefaces with complementary moods to evoke an upbeat, energetic air. It’s the interplay between fonts that gives them energy. The more distant the moods in a typographic palette, the friskier the design will be. Here, three fonts with distinctive silhouettes have been chosen for their contrasting dispositions: the unabashed toughness of Tungsten is a foil for both Archer’s sweetness, and the cheekiness of Gotham Rounded. Math in Pop Culture « 360 Yes, more math in Bones! This one from “The Truth in the Lye”, Season 2 Episode 5. In this episode, a body was found in a bathtub that had been filled with lye, so the body was in an advanced state of decomposition. (My apologies if you’re reading this over a meal.

PI Pi is a name given to the ratio of the circumference of a circle to the diameter. That means, for any circle, you can divide the circumference (the distance around the circle) by the diameter and always get exactly the same number. It doesn't matter how big or small the circle is, Pi remains the same. Pi is often written using the symbol and is pronounced "pie", just like the dessert.
