# 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 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. Fibonacci travelled with him as a young boy, and it was in Bugia (now Béjaïa, Algeria) that he learned about the Hindu–Arabic numeral system.[2] Legacy

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): British have invaded nine out of ten countries - so look out Luxembourg The analysis is contained in a new book, All the Countries We've Ever Invaded: And the Few We Never Got Round To. Stuart Laycock, the author, has worked his way around the globe, through each country alphabetically, researching its history to establish whether, at any point, they have experienced an incursion by Britain. Only a comparatively small proportion of the total in Mr Laycock's list of invaded states actually formed an official part of the empire.

What you need to know about artificial intelligence, and the imminent robot future Do androids dream of electric sheep? That's unclear, but I know for sure that every kid dreams of intelligent, thinking robots -- certainly every kid who goes on to work at CNET, in any case. Today, my sci-fi-fuelled childhood fantasies of a bot with a "brain the size of a planet" are closer than ever to being realised. Artificial intelligence, or AI, the practice of making a machine behave in a smart way, is already changing our world and is, by my reckoning, the most fascinating field of technology right now. But, as one professor I spoke to for this story put it, the "audacity of the attempt to build an intelligent machine" comes with a responsibility to know what we're meddling with. For everyone who ever thumbed through a copy of "I, Robot", mouth agape, here's what you need to know about AI in 2015.

Kevin Annett Exposes Dark Secrets of the Vatican and Its Churches Image credit: www.flickr.com/photos/tejvan/5705851139 Many people don’t realize that the Vatican and its affiliated churches are committing crimes against humanity by financing and supporting child trafficking, wars and genocide. The reason why you don’t hear about these dark secrets of the Vatican in the Western mainstream media is because most Western media outlets are owned and controlled by the New World Order (NWO). The NWO is a secret organization made of secret societies and controlling groups of people that have one thing in common; to establish a one world government to control and enslave the people of the world. For millennia, they have been working very hard from behind the scene to infiltrate government agencies and financial and religious institutions.

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. 40 Maps That Will Help You Make Sense of the World If you’re a visual learner like myself, then you know maps, charts and infographics can really help bring data and information to life.

Robots master skills with ‘deep learning’ technique Robot learns to use hammer. What could go wrong? (credit: UC Berkeley) UC Berkeley researchers have developed new algorithms that enable robots to learn motor tasks by trial and error, using a process that more closely approximates the way humans learn. They demonstrated their technique, a type of reinforcement learning, by having a robot complete various tasks — putting a clothes hanger on a rack, assembling a toy plane, screwing a cap on a water bottle, and more — without pre-programmed details about its surroundings. A new AI approach

How to never worry whether you’re making the wrong decisions again: the secret power of post-mortems Google is one of the most well-known companies on the planet today. But before Google became the successful internet empire they are today, they had many, many failures. And even today, as one of the most famous and successful companies in the world, they continue to fail – and they know that failures will always happen sometimes, no matter how big you get. And of course, all companies fail or mess up sometimes – in big ways and in small ways. What distinguishes Google from many companies in this way is their decision that failure is not something that ideally should be avoided; instead it has become expected and incorporated as part of their process.

Fibonacci Numbers, the Golden section and the Golden String Fibonacci Numbers and the Golden Section This is the Home page for Dr Ron Knott's multimedia web site on the Fibonacci numbers, the Golden section and the Golden string hosted by the Mathematics Department of the University of Surrey, UK. The Fibonacci numbers are The golden section numbers are 0·61803 39887... = phi = φ and 1·61803 39887... = Phi = Φ Watch 1000 Years of European Borders Change In 3 Minutes The whole world is watching the crisis in Crimea, and Russia faces off with the USA and European superpowers. The dispute centers around which country the territory should belong to, and it may seem shocking in today’s modern era, but the borders of Europe have never been solid. In this time-lapse video, you can see how 1000 years of European history plays havoc on the stability of the border we take for granted today. This time-lapse video has never been more relevant. As the eyes of the world are fixed on events in Ukraine and Crimea, its good to have a little perspective on the ever-changing flux of borders throughout time.

Consciousness: Eight questions science must answer Consciousness is at once the most familiar and the most mysterious feature of our existence. A new science of consciousness is now revealing its biological basis. Once considered beyond the reach of science, the neural mechanisms of human consciousness are now being unravelled at a startling pace by neuroscientists and their colleagues. I've always been fascinated by the possibility of understanding consciousness, so it is tremendously exciting to witness – and take part in – this grand challenge for 21st century science. Here are eight key questions that neuroscientists are now addressing:

What One Product Makes the Most Money For Each Nation? Check This Map Mali makes makes the most money from exporting cotton. New Zealand's most valued export is dairy. India profits most from selling precious stones abroad, and Sri Lanka's hottest export is tea. The export topography of each country's most valuable product demonstrates where countries trading in the world market are yielding financial gains. Although some are extremely obvious, other countries benefit financially from unlikely sources.

The Three Laws of Transhumanism and Artificial Intelligence Wikimedia Commons I recently gave a speech at the Artificial Intelligence and The Singularity Conference in Oakland, California. There was a great lineup of speakers, including AI experts Peter Voss and Monica Anderson, New York University professor Gary Marcus, sci-fi writer Nicole Sallak Anderson, and futurist Scott Jackisch. All of us are interested in how the creation of artificial intelligence will impact the world. My speech topic was: The Morality of an Artificial Intelligence Will be Different from our Human Morality 40 maps that explain the world Maps can be a remarkably powerful tool for understanding the world and how it works, but they show only what you ask them to. So when we saw a post sweeping the Web titled "40 maps they didn't teach you in school," one of which happens to be a WorldViews original, I thought we might be able to contribute our own collection. Some of these are pretty nerdy, but I think they're no less fascinating and easily understandable. A majority are original to this blog, with others from a variety of sources. I've included a link for further reading on close to every one.
