# Golden ratio

Line segments in the golden ratio In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. The figure on the right illustrates the geometric relationship. The golden ratio is also called the golden section (Latin: sectio aurea) or golden mean.[1][2][3] Other names include extreme and mean ratio,[4] medial section, divine proportion, divine section (Latin: sectio divina), golden proportion, golden cut,[5] and golden number.[6][7][8] Some twentieth-century artists and architects, including Le Corbusier and Dalí, have proportioned their works to approximate the golden ratio—especially in the form of the golden rectangle, in which the ratio of the longer side to the shorter is the golden ratio—believing this proportion to be aesthetically pleasing (see Applications and observations below). Calculation Two quantities a and b are said to be in the golden ratio φ if Therefore, Multiplying by φ gives and History Related:  mathematics

What’s Golden | Jason Santa Maria Ratios and the rule of thirds are relative properties and are derived from inclusive measurements. Which means that not only is a height dependent on and relative to a width, but in order to have the full desired effect, a viewer must be able to see or perceive the boundaries of an object. We usually just regard a piece of work as a whole entity, in much the same way we perceive a painting. But you don’t go to the Louvre and see one-third of the Mona Lisa, you see the entirety of the painting in one go (crowds notwithstanding). The web is more like looking through a window outside of the Louvre that partially obscures your view. Nature of the Medium There are lots of tutorials, articles, and books that approach the topic of using ratios online. By its very nature the web is a medium of displacement; content is not tied to being viewed on a specific device, screen, browser, and most importantly, at a standard size. Letting Go I’ve been beating myself up about stuff like this for years.

Divide By Zero About To Divide by Zero is an internet slang term describing an action that leads to an epic failure or theoretically unlikely disaster, such as an earth-shattering apocalypse or a wormhole in the time-space continuum. The concept of division by zero is also associated with the phrase “OH SHI-,” which represents the response of someone that is cut off mid-sentence as a result of the disaster. Origin The earliest known reference to division by zero can be found in a YTMND site titled “1/0 !!!!!!!!!!!!” However, according to Encyclopedia Dramatica, the phrase is said to have originated on 4chan’s /b/ (random) board, with its earliest dating to December 8th, 2006. In Mathematics In math with real numbers, values that represent quantities along a continuous line, division by zero is an undefined operation, meaning it is impossible to have a real number answer to the equation.

12 Laws and Principles to Aid You in Your Design | Onextrapixel - Web Design & Development Magazine Centuries of observation by men and women from all walks of life have revealed important principles of design and orderliness that tend to naturally create a positive, common human reaction.

Ding Dong Bell The sound of bells In East Anglia, as you look across the fens, villages appear almost like little islands (indeed some of them were islands before the fens were drained) and these villages are dominated by big churches with tall towers. In the past people regulated their lives and passed messages by ringing church bells, which could be heard for miles around, telling the time of day, and giving news of births, marriages and deaths in a parish. The following quotation comes from the ringer's rules from Southhill in Bedfordshire "When mirth and pleasure is on the wing we ring; at the departure of a soul we toll". Bell ringing is good exercise for the body and mind, the bells are heavy and the bellringers have to remember the changes. The mathematics of the changes With four bells there are of course many more possibilities; there are twenty four different permutations or orders in which the bells can be rung and there are four bell ringing changes.
