History of Mathematics based on figures

1. Thales (624-550 BC)
  • May be called the first mathematician who formulated the theorem or proposition, where tradition has become more clear after translated by Euclid. The foundation of mathematics as an applied science must have been placed by Thales before appearing Pythagoras who make numbers.
2. Pythagoras (582-496 BC)
  • Pythagoras was the man who first sparked the axioms, postulates-postulates that need to be translated first pitch in the developed geometry. Pythagoras was not a finding of a theorem of Pythagoras, but he managed to create mathematical proofs. Pythagorean Brotherhood discovered  2 as irrational numbers.
3. Socrates (427-347 BC)
  • He is a great philosophy from the Greeks. He also became the creator of all-purpose doctrine, because it was philosophy called idealism. His teachings were born because of interaction with the sophists. Plato is thought to carry away the first expert who received not understand the nature of things.
4. Ecluides (325-265 BC)
  • Euclid called the "Father of Geometry" because menemuka number theory and geometry.Subjects covered are the forms, Pythagorean theorem, equations in algebra, circle, tangent, the geometry of space, the theory of proportion and others. Eukluides discovery tools such as slide rules and terms.
5. Archimedes (287-212 BC)
  • He applied the principles of physics and mathematics. And also find the calculation of π (pi) in calculating the size of the circle. He was the greatest mathematician of all time and in ancient times. Three kaaarya Archimedes discusses plane geometry, namely the measurement loop, the quadrature of parabola and spirals.
6. Appolonius (262-190 BC)
  • His concept of parabola, hyperbola, and ellipse many contribute to modern astronomy. He is a mathematician pliers expert in geometry. Theorem Appolonius linking some elements in the triangle.
7. Diophantus (250-200 BC)
  • He is the "Father of Algebra" for the Babylonian who developed the concepts of Babylonian algebra. A Greek mathematician who lived in Alexandria. Great works of Diophantus of arithmetic book, the book's first essay on algebra system. Preserved part of solving arithmetic Diophantus contains approximately 130 questions that generate first-degree equations.

History of google


Google began in March 1996 as a research project by Larry Page and Sergey BrinPh.D. students at Stanford working on the Stanford Digital Library Project (SDLP). The SDLP's goal was “to develop the enabling technologies for a single, integrated and universal digital library." and was funded through the National Science Foundation among other federal agencies. In search for a dissertation theme, Page considered—among other things—exploring the mathematical properties of the World Wide Web, understanding its link structure as a huge graph. His supervisor Terry Winograd encouraged him to pick this idea (which Page later recalled as "the best advice I ever got" and Page focused on the problem of finding out which web pages link to a given page, considering the number and nature of such backlinks to be valuable information about that page (with the role of citations in academic publishing in mind). In his research project, nicknamed "BackRub", he was soon joined by Sergey Brin, a fellow Stanford Ph.D. student supported by a National Science Foundation Graduate Fellowship.Brin was already a close friend, whom Page had first met in the summer of 1995 in a group of potential new students which Brin had volunteered to show around the campus. Page's web crawler began exploring the web in March 1996, setting out from Page's own Stanford home page as its only starting point. To convert the backlink data that it gathered into a measure of importance for a given web page, Brin and Page developed the PageRank algorithm. Analyzing BackRub's output—which, for a given URL, consisted of a list of backlinks ranked by importance—it occurred to them that a search engine based on PageRank would produce better results than existing techniques (existing search engines at the time essentially ranked results according to how many times the search term appeared on a page). A small search engine called Rankdex was already exploring a similar strategy.
Convinced that the pages with the most links to them from other highly relevant Web pages must be the most relevant pages associated with the search, Page and Brin tested their thesis as part of their studies, and laid the foundation for their search engine. By early 1997, the backrub page described the state as follows:
Some Rough Statistics (from August 29th, 1996)
Total indexable HTML urls: 75.2306 Million
Total content downloaded: 207.022 gigabytes
...
BackRub is written in Java and Python and runs on several Sun Ultras and Intel Pentiums running Linux. The primary database is kept on an Sun Ultra II with 28GB of disk. Scott Hassan and Alan Steremberg have provided a great deal of very talented implementation help. Sergey Brin has also been very involved and deserves many thanks.
-Larry Page page@cs.stanford.edu
Originally the search engine used the Stanford website with the domain google.stanford.edu. The domain google.com was registered on September 15, 1997. They formally incorporated their company, Google Inc., on September 4, 1998 at a friend's garage in Menlo Park, California.
Both Brin and Page had been against using advertising pop-ups in a search engine, or an "advertising funded search engines" model, and they wrote a research paper in 1998 on the topic while still students. However, they soon changed their minds and early on allowed simple text ads.
The name "Google" originated from a misspelling of "googol," which refers to the number represented by a 1 followed by one-hundred zeros (although Enid Blyton used the word decades earlier in "Google Bun" - Chapter IX, The Magic Faraway Tree). Having found its way increasingly into everyday language, the verb, "google," was added to the Merriam Webster Collegiate Dictionary and the Oxford English Dictionary in 2006, meaning, "to use the Google search engine to obtain information on the Internet."
By the end of 1998, Google had an index of about 60 million pages.The home page was still marked "BETA", but an article in Salon.com already argued that Google's search results were better than those of competitors like Hotbot or Excite.com, and praised it for being more technologically innovative than the overloaded portal sites (like Yahoo!, Excite.com, Lycos, Netscape's NetcenterAOL.comGo.com and MSN.com) which at that time, during the growing dot-com bubble, were seen as "the future of the Web", especially by stock market investors.
In March 1999, the company moved into offices at 165 University Avenue in Palo Alto, home to several other noted Silicon Valley technology startups. After quickly outgrowing two other sites, the company leased a complex of buildings in Mountain View at 1600 Amphitheatre Parkway from Silicon Graphics (SGI) in 1999. The company has remained at this location ever since, and the complex has since become known as the Googleplex (a play on the word googolplex, a number that is equal to 1 followed by a googol of zeros). In 2006, Google bought the property from SGI for $319 million.
The Google search engine attracted a loyal following among the growing number of Internet users, who liked its simple design. In 2000, Google began selling advertisementsassociated with search keywords. The ads were text-based to maintain an uncluttered page design and to maximize page loading speed. Keywords were sold based on a combination of price bid and click-throughs, with bidding starting at $.05 per click. This model of selling keyword advertising was pioneered by Goto.com (later renamed Overture Services, before being acquired by Yahoo! and rebranded as Yahoo! Search Marketing). While many of its dot-com rivals failed in the new Internet marketplace, Google quietly rose in stature while generating revenue.Google's declared code of conduct is "Don't be evil", a phrase which they went so far as to include in their prospectus (aka "S-1") for their IPO, noting, "We believe strongly that in the long term, we will be better served — as shareholders and in all other ways — by a company that does good things for the world even if we forgo some short term gains."

Aboriginal Heritage Sculptures In the Australian Rain Forest

Aboriginal population in Australia Continent Now Is Tough It was found Or Could It said Rarely.But What They Leave very artsy. The proof With Some Carved Human Statue The difficulty level is very high. Created in the early century - 18th by sculptor William Ricketts who was appointed to the Aborigines because of their proximity to their lives. Made of wood trees that are in the Australian rainforest, a masterpiece is created.
Preview of Life is a work based Aboriginal enshrined By William Ricketts In Pahatannya. A native Australian descendants have become part of Aboriginal.

These mesmerizing sculptures are the work of William Ricketts, a rare Australian born in 1898 who was in awe of the connection the Aborigine people have with the land.



The clay figures, which Ricketts created on site in his home on Mount Dandenong, near Olinda, express his devout philosophy that all people need to act as custodians of the natural environment just as the Aboriginal people do.




Ricketts gained his deep understanding of Aboriginal culture during frequent trips to Central Australia, where he lived with the Pitjantjatjara and Arrernte people from 1949 -1960. They soon adopted him as one of their own and willingly posed for the sculptures that would become their legacy.





William Ricketts died in 1993 at the ripe old age of 94 but he will always be remembered as his figure, too, is dotted around the tranquil fern gully, forever connected to both the family and the land he so loved.
