تاریخچه گوگل
تاریخچه گوگلگوگل کار خود را به عنوان یک پروژه تحقیقات در اوایل سال 1996 به وسیله "لاری پیج" و "سرجی برین" که دو دانشجو PHD از دانشگاه "استنفورد" بودند شروع کرد. آنها می خواستند فرضیه خود را در مورد اینکه "اگر موتورهای جستجو پایه و اساسشان بر روی تحلیل رابطه بین وب سایت ها باشد نتیجه بهتری نسبت به روش های رایج و کلی آن زمان داشت" را گسترش دهند. این روش را در اول نامیدند "BackRub " به خاطر اینکه سیستم لینکهای قبلی و داد شده را چک می کرد و اهمیت یک سایت را تخمین می زد. (در آن زمان یک موتور جستجو کوچکی به نام "RankDex"ُ با همین استراتژی کار می کرد.)
آنان متقاعد شدند که صفحاتی که لینکهای
بیشتری به آنها از طرف صفحات معتبر دیگرداده شده دارای اهمیت و ارتباط بیشتری میباشند."پیچ" و "برین" تصمیم گرفتند ایده و فرضیه و یافته خود را بعنوان قسمتی از تحصیلات دانشگاهی برای موتور جستجوی خودشان انجام دهند.
دامین" www.google.com "را در پانزدهم سبتامبر سال 1997 ثبت کردند. سپس رسما کمپانی گوگل را در هفتم سال 1998 در گاراژ یکی از دوستانشان در "Melno Park " در کالیفرنیا ایجاد کردند. سپس در فبریه سال 1999 کمپانی منتقل شد به دفتری در "165 University Avenue" در "پالوآلتو" به خانه شماری از "Silicon Valley Technology" و ادامه کار داد.گوگل در سال 1999 شکست بسیار بزرگی خورد، زمانی "altavista" مشهورترین موتور جستجو نزد کاربران مطلع بود.پس از این شکست گوگل دوباره به صورت دریچه ای جدید بازگشت و آن کابران را منحرف کرد.سپس مکان گوگل به سرعت هر چه تمام تر در "University Avenue"گسترش یافت. بعد گوگل در ساختمان های بسیار زیادی در کنار هم در " Amphitheater Parkway" سال 2003 مستقر شد.
موتور جستجو گوگل به خاطر سادگی و تمیزی طراحی(تقلید شده از "altavista" اولیه) و نتایج جستجو مرتبط آن در میان کاربران اینترنت جای بخصوصی برای خود باز کرد.در سال 2000 گوگل شروع کرده بود به فروش تبلیغات به وسیله فروش کلمات کلیدی که مرتبط و آشنا تر برای کاربران بود.تبلیغات بر اساس متون بودند تا صفحات دارای طراحی ساده و سبک و به اصطلاح "Fast-loading" باشند. مفهوم و ایده فروش کلمات کلیدی (Keywords) برای تبلیغات به وسیله "Overtrue" برای اولین بار بنیان گذاشته شده بود.
اینجا سابقا "Goto.com" بود.هنگامی که بسیاری از دات کامها و دوستان داشتند سقوط می کردند، گوگل بی سر و صدا صعود و پیشرفت بسیاری کرد و دریچهای بسیاری از سود و منفعت برایش باز شد.
U.S. Patent 6,285,999 مکانیزم ارزشدهی گوگل
به صفحات(PageRank) در چهارم سبتامر سال 2001 برنامه ریزی شد. حق امتیاز آن به صورت رسمی به دانشگاه استنفورد واگذار شد و در لیستهای "Laerence Page" به عنوان یک اختراع ثبت شد.
در فبریه سال 2003 ، "پیرا لبز" را که الان صاحب "Blogger" و مبتکر و هدایت کننده وب سایت فضا دهنده گوگل برای وبلاگ می باشد را بدست آورد . این دستاورد به نظر می آمد که هم طراز با ماموریتها و موقعیتهای کلی گوگل نباشد. هرچند که این حرکت توانایی کمپانی را برای بدست آوردن اطلاعات از این سو و آنسو از پستهای بلاگها تامین می کرد تاسرعت و روابط بین موضوعهایی که شامل "اخبار گوگل" می شود رابهتر کند.
در اوج موفقیت گوگل در اوایل سال 2004 ، او دارای بیشترین درخواست جستجو نسبت به "Yahoo! " و "AOL" و "CNN.[2] " که حدود 80 درصد می باشد را داشت. بخشی از مردم گوگل را در فبریه سال 2004 زمانی یاهو! تکنولوژی جستجو گوگل را به کنار گذاشت کنار گذاشتند تا نتایج مستلی بدست آورند. به خاطر افزایش جمعیت مدارک و استفاده کنندگان گوگل واژه "Google " در آمریکای شمالی به عنوان فعل و اسم دخیل به معنی "انجام دادن جستجو (مخصوصا در موتور گوگل)" وارد زبان آنان (فکر کنم انگلیسی) شد.
گوگل کدهای اداره کننده اش را که موسوم به "Don't Be Evil" بود اظهار و فاش کرد.آنها سایتشان حاوی چیزهای خنده دار و جالبی از جمله طراحی و دگرگونیهای کارتونی [3] در لوگوی خود برای موقعیتهای مخصوص(مثل نوروز امسال) و نمایش سایت با زبانهای ساختگی مانند زبان خنده دار "Kilingon [4] " و "Leet[5] " و همچین احمقانه ترین جکهای آپریل"[6] "در مورد خود کمپانی.
حدس زده می شود که واکنش و پاسخ گوگل به جستجوها یاهو! شخصی می شود. از اطلاعات شخصی مانند "Orkut , Gmail , Froogle " برای دادن نتایج بر اساس چیزهای شخصی استفاده می شود. در حقیقت، یک قسمت برای جستجوهای شخصی گوگل "]7[beta" و "Google Labs" قرار دادند که به صورت آزمایشی در حال فعالیت می باشند.
ریشه یابی لغت گوگل
واژه "google" نزدیک به واژه "Googol" که به وسیله "میلتون سیروتا" که برادر زاده ریاضیدان بزرگ آمریکایی "ادوارد کانسر(1993)" بود ابدا شد تا عددی را نشان دهد که یک به دنبال آن 100 تا صفر باشد.استفاده گوگل از این لفظ ماموریت گوگل را برای سازماندهی کردن انبوهی از اطلاعات حاضر در وب بازتاب کرد.علاوه بر نمایش آن، ساختمان اصلی و دفتری گوگل"Googleplex" نامیده شد. گوگلپلکس از 1 هست تا "googol"تا 0 (100تا صفر) و ساختمان اصلی دفتری آن متشکل است از تعداد و انبوهی از ساختمانهایی پیچیده.( "cf-multiplex" , "Cineplex" و غیره)
اولین پیشنهاد فروش سهام به عموم و بازرگانی(IPO)
سرمایه گذاران عمده و اصلی گوگل که سرمایه ی اولیه بازرگانی را دادند "کلاینر پرکین کافیلد" و "بایرز" و "سرمایه سکویا" می باشند. در اکتبر سال 2003 هنگامی که بحث بر IPO (Initial Public Offering of shares) بود ، امکان پیشنهاد همکاری و ادغام دو کمپانی از طرف مایکروسافت بود و داده شد ولی به آن اندازه جامه عمل به خود نپوشید.
در ژانویه سال 2004 گوگل خبر داد از اجاره کردن "مرگان استنلی" و "گلدمن ساچز گروپ" منظم کردن IPO . آن IPO (یکی از بیشترین چیزهای که از آن انتظار می رفت در تاریخ) طرح ریزی شد برای بیشتر از 4 ملیارد دلار .بر اساس گفته بانکداری که در این معمله پی گیر بود، این معامله چیزی حدود 12 میلیارد جمع آوری سرمایه ی بازار را برای گوگل داشته است.(Market Capitalization).
در بیست و نهم آپریل سال 2004 گوگل " "S-1 Fromرا با سیستمهای امنیتی و کمسیون بورسی برای یک IPO ضبط و بایگانی کرد تا آن را بالا ببرد به اندازه "USD $2,718,281,828(منظور دلار آمریکا)" (نکته جالب و خنده دار این است که این مقدار برار عدد ریاضی "e = 2.718281828..." است!). ضبط و بایگانی این قضیه فاش شد زمانی که گوگل از سال 2001 سودی از $105.6 میلیون دلار از سود سهام تا $961.8 میلیون دلار تا سال 2003 بدست آورد.
در ماه می سال 2004 رسما برای IPO از "گلدمن ساچز" و "مرگان استنلی" و "Credit Suisse First Boston" جدا شد تا در بیمه عضو شود(Underwriters). آنها اولین پیشنهاد خود(IPO) را به صورتی غیر معمول در مزایده قرار دادند( به طور کامل و دقیق در "Dutch Auction") و به همین ترتیب هر کسی می توانست در پیشنهادات شرکت کند.
بعد از مقداری لغزشهای اولیه که به خاطر تخصصی بودن آن بنده ذکر نکردم، اولین پیشنهاد عمومی(IPO) گوگل در نوزدهم آگست سال 2004 19,605,052 سهم در هر سهم $85 پیشنهاد می شد. از آن ، 14,142,135 (یک چیز خنده دار دیگر این بود که این مقدار برابر با √2 = 1.4142135... بود!) معلق بود در دست گوگل و 5,462,917 از فروش به سهام داران بدست آمد. این حراج رسید به$1.67 میلیارد که از آن تقریبا $1.2 میلیارد رفت برای گوگل. 271 میلیون سهم گوگل به دست خود گوگل کنترل و اداره می شد. آن IPO برای گوگل $23 میلیارد از سرمایه بازار حاصل کرد . بسیاری از کارمندان گوگل به سرعت میلیونر شدند. به صورت جالبی Yahoo! هم که 2.7 سهم از گوگل داشت سود عظیمی بدست آورد. این کمپانی وارد بازار سهام و ارزی"NASDAQ" با نشان "GOOG" شد.
امروز گوگل
از آن IPO که آنان را میلیونر کرد به بعد ، سهام سرمایه بازاری گوگل بسیار صعود کرد و قیمت سهام به بیش از دو برابر افزایش یافت.در نوزدهم آگست سال 2004 مقدار برجسته سهم ها 172.85 میلیون بود. در ژانویه سال 2005 سهم ها به صورت برجسته ای از 100 میلیون به 273.42 میلیون افزایش یافته که 53% آن به دست داخلیها گرفته شد که این وضعیت معلق را به 127.70 میلیون رساند ( بیشتر از 110 میلیون سهم در اولین روز تجاری). گفته شده است که دو موسس و بنیانگذار چیزی حدود 30% از سهمها را گرفته اند. کمپانی هیچ خبری در مورد سهم های نگهداری شده در آمار Q3 2004 نداده است.
در یکم ژون سال 2005 سهم های گوگل سودی نزدیک 4 درصد بعد از "Credit Suisse First Boston" بدست آورد که قیمت هدف و نهایی آنان در سهام را به $350 رسانید. در همین زمینه شایعاتی در جامعه ی تجاری گسترش یافت که گوگل به زودی داخل "S&P 500" می شود (منبع: Google Shares Rise on New Price Target . L.A.Times). زمانی که کمپانی در لیست "S&P 500" اولین بود آنها به نوعی بیشترین قیمت سهام در کل بازار را تجربه کردند. در هفتم ژون سال 2005 گوگل ارزشی معادل با $80 میلیارد یافت و این آنان را بزرگ ترین کمپانی مدیا در جهان به وسیله ارزش بازار سهام ساخت (حتی از"Time Warner" هم جلو افتادند!). البته اندکی بعد ، ارزش سهام آنان مقداری نزول کرد و دوباره "Time Warner" با ارزش تر شد.
درآمد کارمندان
حقوق کارمندی در گوگل، بررسی شده که کمتر از استاندارد صنعت است. به عنوان مثال ریس سیستم درامدی کمتر از $33,000–37,000 دارد که این مقدار از طبقات استاندارد "Bay Area" کمتر است.
هرچند، این حقوق کم این چشم انداز
ستاره ای گوگل در کارش ادامه به جذب درخواست
بیش تر از حال می کند
( در این رابطه بیشتر از"Bay Area" کمپا
نی ها).در نتیجه این طوری که گزارش
شده گوگل نقش بسزایی در شغلسازی
داشته است.(حتی برای وکیلان بی کار
و دنبال کار!)
مدیریت
به این صورت« شغل:اسم ، پاداش (در ژون سال 2005)، سن»
CFO (chief executive officer ): Eric E. Schmidt ، 50, $82K
CFO (chief financial officer ): George Reyes ، 51, $781K
ریس تکنولوژی: Sergey Brin ، 31, $45K
ریس تولیدات و محصولات: Larry E. Page ، 32, $45K
نایب ریس فروش جهانی: Omid Kordestani ، 41, $572K (ایشان ایرانی هستند!)
نایب ریس شرکت توسعه و اطلاعات: David C. Drummond ، 42, $776K
طبق گذارشات رسیده شده "پیج" و "برین" در سال 2004 درآمدی برابر $1 داشته اند. ولی بعد از آن IPO در آگوست سال 2004 بر اساس گذارش ها درامد آنها به $1 در ثانیه رسید. "پیج" و "برین" و "اسکمیدت" تمام پیشنهاد های اخیر را کاهش دادند و پاداش و درامد گوگل را افزایش دادند.
NASA History in Brief
NASA History in Brief
October 1, 1958, the official start of the National Aeronautics and Space Administration (NASA), was the beginning of a rich history of unique scientific and technological achievements in human space flight, aeronautics, space science, and space applications. Formed as a result of the Sputnik crisis of confidence, NASA inherited the earlier National Advisory Committee for Aeronautics (NACA), and other government organizations, and almost immediately began working on options for human space flight. NASA's first high profile program was Project Mercury, an effort to learn if humans could survive in space, followed by Project Gemini, which built upon Mercury's successes and used spacecraft built for two astronauts. NASA's human space flight efforts then extended to the Moon with Project Apollo, culminating in 1969 when the Apollo 11 mission first put humans on the lunar surface. After the Skylab and Apollo-Soyuz Test Projects of the early and mid-1970s, NASA's human space flight efforts again resumed in 1981, with the Space Shuttle program that continues today to help build the International Space Station.
Building on its NACA roots, NASA has continued to conduct many types of cutting-edge aeronautics research on aerodynamics, wind shear, and other important topics using wind tunnels, flight testing, and computer simulations. NASA's highly successful X-15 program involved a rocket-powered airplane that flew above the atmosphere and then glided back to Earth unpowered, providing Shuttle designers with much useful data. The watershed F-8 digital-fly-by-wire program laid the groundwork for such electronic flight in many other aircraft including the Shuttle and high performance airplanes that would have been uncontrollable otherwise. NASA has also done important research on such topics as "lifting bodies" (wingless airplanes) and "supercritical wings" to dampen the effect of shock waves on transsonic aircraft.
Additionally, NASA has launched a number of significant scientific probes such as the Pioneer and Voyager spacecraft that have explored the Moon, the planets, and other areas of our solar system. NASA has sent several spacecraft to investigate Mars including the Viking and Mars Pathfinder spacecraft. The Hubble Space Telescope and other space science spacecraft have enabled scientists to make a number of significant astronomical discoveries about our universe.
NASA also has done pioneering work in space applications satellites. NASA has helped bring about new generations of communications satellites such as the Echo, Telstar, and Syncom satellites. NASA's Earth science efforts have also literally changed the way we view our home planet; the Landsat and Earth Observing System spacecraft have contributed many important scientific findings. NASA technology has also resulted in numerous "spin-offs" in wide-ranging scientific, technical, and commercial fields. Overall, while the tremendous technical and scientific accomplishments of NASA demonstrate vividly that humans can achieve previously inconceivable feats, we also are humbled by the realization that Earth is just a tiny "blue marble" in the cosmos.

The History of Yahoo!
The History of Yahoo! - How It All Started...
Yahoo! began as a student hobby and evolved into a global brand that has changed the way people communicate with each other, find and access information and purchase things. The two founders of Yahoo!, David Filo and Jerry Yang, Ph.D. candidates in Electrical Engineering at Stanford University, started their guide in a campus trailer in February 1994 as a way to keep track of their personal interests on the Internet. Before long they were spending more time on their home-brewed lists of favorite links than on their doctoral dissertations. Eventually, Jerry and David's lists became too long and unwieldy, and they broke them out into categories. When the categories became too full, they developed subcategories ... and the core concept behind Yahoo! was born.
The Web site started out as "Jerry and David's Guide to the World Wide Web" but eventually received a new moniker with the help of a dictionary. The name Yahoo! is an acronym for "Yet Another Hierarchical Officious Oracle," but Filo and Yang insist they selected the name because they liked the general definition of a yahoo: "rude, unsophisticated, uncouth." Yahoo! itself first resided on Yang's student workstation, "Akebono," while the software was lodged on Filo's computer, "Konishiki" - both named after legendary sumo wrestlers.
Jerry and David soon found they were not alone in wanting a single place to find useful Web sites. Before long, hundreds of people were accessing their guide from well beyond the Stanford trailer. Word spread from friends to what quickly became a significant, loyal audience throughout the closely-knit Internet community. Yahoo! celebrated its first million-hit day in the fall of 1994, translating to almost 100 thousand unique visitors.
Due to the torrent of traffic and enthusiastic reception Yahoo! was receiving, the founders knew they had a potential business on their hands. In March 1995, the pair incorporated the business and met with dozens of Silicon Valley venture capitalists. They eventually came across Sequoia Capital, the well-regarded firm whose most successful investments included Apple Computer, Atari, Oracle and Cisco Systems. They agreed to fund Yahoo! in April 1995 with an initial investment of nearly $2 million.
Realizing their new company had the potential to grow quickly, Jerry and David began to shop for a management team. They hired Tim Koogle, a veteran of Motorola and an alumnus of the Stanford engineering department, as chief executive officer and Jeffrey Mallett, founder of Novell's WordPerfect consumer division, as chief operating officer. They secured a second round of funding in Fall 1995 from investors Reuters Ltd. and Softbank. Yahoo! launched a highly-successful IPO in April 1996 with a total of 49 employees.
Today, Yahoo! Inc. is a leading global Internet communications, commerce and media company that offers a comprehensive branded network of services to more than 345 million individuals each month worldwide. As the first online navigational guide to the Web, www.yahoo.com is the leading guide in terms of traffic, advertising, household and business user reach. Yahoo! is the No. 1 Internet brand globally and reaches the largest audience worldwide. The company also provides online business and enterprise services designed to enhance the productivity and Web presence of Yahoo!'s clients. These services include Corporate Yahoo!, a popular customized enterprise portal solution; audio and video streaming; store hosting and management; and Web site tools and services. The company's global Web network includes 25 World properties. Headquartered in Sunnyvale, Calif., Yahoo! has offices in Europe, Asia, Latin America, Australia, Canada and the United States.

چگونه برای خود یک وب سایت بسازیم؟
چگونه برای خود یک وب سایت بسازیم؟
بسیاری از افراد می پندارند داشتن وب سایت فقط یک آرزوست اما این چنین نیست و با کمی تلاش و پشتکار می توانید برای خود یک وب سایت بسازید و آنرا مدیریت کنید و لذت ببرید.
برای رسیدن به این هدف چند مرحله در پیش رو دارید که به ترتیب توضیح می دهم:
اولین گام - طراحی یک سایت
اولین قدم برای ساختن یک وب سایت طراحی آن می باشد. برای طراحی وب سایت خود می توانید از نرم افزارهایی مانند: Microsoft FrontPage و یا Macromedia DreamWeaver استفاده نمایید. در طراحی سایت باید نکاتی را رعایت کنید، از آن جمله می توان به حجم آن اشاره نمود، وب سایت شما باید در عین زیبایی دارای حداقل حجم باشد زیرا بسیاری از کاربران ایرانی سرعت وب پایینی دارند و در صورتی که حجم سایت شما بالا باشد دیر بارگزاری خواهد شد و بازدید کننده ناراضی بوده و احتمال بازدید دوباره تا نصف کاهش می یابد.
گام دوم - خرید یک هاست مناسب
دومین قدم برای داشتن یک وب سایت موفق تهیه یک هاست مناسب می باشد. هنگام خرید هاست باید دقت کنید که هاست مورد نظر مناسب باشد. مثلا اگر می خواهید فقط یک سایت شخصی داشته باشید تهیه 500 مگابایت هاست به معنای اتلاف هزینه است و یا اگر قصد دارید در سایت خود از ASP استفاده کنید حتما باید هاست ویندوز و در صورتی که می خواهید از زبان PHP در سایت خود استفاده نمایید حتما هاست لینوکس تهیه کنید.
هنگام خرید هاست به مواردی مانند پشتیبانی، پهنای باند، تعداد دیتابیس و ایمیل و ساب دامین نیز دقت داشته باشید. برای خرید هاست لازم نیست به شرکت یا موسسه ای مراجعه کنید می توانید به صورت آنلاین نیز هاست تهیه کنید، برای خرید هاست بصورت آنلاین به سایت پارسی نیک مراجعه کنید.
گام سوم - نصب و راه اندازی سایت
قدم سوم راه اندازی سایت است که عبارتست از آپلود فایل های لازم بر روی هاستی که خریداری نموده اید، اگر قصد دارید برنامه های خاصی مانند انجمن های فارسی یا فروشگاههای الکترونیک را بر روی سایت خود داشته باشید ابتدا باید فایلهای مربوطه را آپلود و سپس برنامه مذکور را نصب کنید.
در مورد نصب انجمن های فارسی و فروشگاههای آنلاین و دیگر برنامه های آنلاین در مقالات بعدی خواهم نوشت.
گام چهارم - تبلیغات و پیشبرد اهداف سایت
پس از راه اندازی کامل سایت نوبت به تبلیغ و پیشبرد اهداف سایت می باشد. این اهداف می تواند فروش محصولات یا معرفی شرکت و خدمات و ... باشد.
دقت داشته باشید که تبلیغ در هر سایتی برای شما مفید نخواهد بود، هنگامی که می خواهید در یک سایت یا بلاگ تبلیغ خود را قرار دهید به یک مورد باید دقت داشته باشید و آن پرطرفدار بودن و بالا بودن سایت یا بلاگی است که می خواهید درآن تبلیغ کنید. همچنین می توانید با مدیران سایتها و بلاگها توافق کرده و تبادل بنر و لینک نمایید.
همانطور که می بینید پارس آی.تی مکانی مناسب برای تبلیغ سایت یا بلاگ شماست البته با هزینه ای بسیار ناچیز، پس اگر سه قدم پیشین را با موفقیت به پایان رسانده اید هم اکنون برای تبلیغ در پارس آی.تی اقدام کنید. یک کامنت بگذارید یا با آی دی زیر تماس بگیرید:

BLAISE PASCAL Biography
Born: June 19, 1623
Clermont-Ferrand, France
Died: August 19, 1662
Paris, France
French mathematician, scientist, and philosopher
Blaise Pascal was an influential mathematical writer, a master of the French language, and a great religious philosopher (a person who seeks wisdom). He began making contributions to mathematics at a very young age. The computer programming language "Pascal" is named after him.
Young master of geometry
Blaise Pascal was born at Clermont-Ferrand, France, on June 19, 1623. His father, Étienne, was a civil servant and served as king's counselor. Blaise's mother, Antoinette, died in 1626. Blaise was three years old at the time and had two sisters, Gilberte and Jacqueline. In 1631 the family moved to Paris, France.
Blaise's father did not like the way school was taught at that time and instructed all three children at home himself. He placed special emphasis on learning Latin and Greek. He did not expose Blaise to geometry because he felt the topic was too enticing and attractive. Geometry is the branch of mathematics that deals with points, lines, angles, surfaces, and solids. He thought that if exposed to geometry and mathematics too soon, Blaise would abandon the study of classics.
This ban on mathematics merely served to make Blaise even more curious. On his own he experimented with geometrical figures. He invented his own names for geometrical terms because he had not been taught the standard terms. Some people believe that

Blaise was twelve years old when he started attending meetings of a mathematical academy with his father. Other scholars think that he did not attend the meetings until he was about sixteen. Whichever was the case, he was far younger than the adults who were there.
In 1640 the Pascal family moved to Rouen, France. Blaise was still taught mainly by his father. He worked very hard, but was frequently in poor health. During this time he developed a new theorem, or mathematical formula that can be proven, in geometry. He sometimes referred to this theorem as a "mystic hexagram." It was quite different from geometry that dealt with measured properties of figures. It was the foundation for an important, and, at the time, almost entirely undeveloped branch of mathematics.
In 1640, at age sixteen, Pascal wrote a book, Essay on Conics. It deals with the geometry of cones. He gave the mystic hexagram central importance in this book. At the age of nineteen, Pascal invented a calculating machine. It was able to add and subtract by having a person move a series of gears and cylinders. This was an early form of a computer.
Jansenists and Port Royal
In 1646 Pascal's father had an accident and was confined to his house. Some neighbors who were Jansenists came to visit him. The Jansenists were a religious group formed by Cornelius Jansen (1585–1638). Their beliefs were very different from the teachings of the Jesuits, who were the most influential group at the time. The Pascals began adopting the Jansenist beliefs. As a result, they received opposition from the local Jesuits.
After Étienne Pascal's death in 1651, Pascal's sister Jacqueline joined the Jansenists at their convent in Port Royal. Pascal continued to enjoy a more worldly life. He had a number of aristocratic (upper-class) and famous friends and money from his patrimony (inheritance) to support himself. In 1654, however, he completely converted to Jansenism, and joined his sister at the convent at Port Royal.
Provincial Letters
In 1655 the writer Antoine Arnauld (1612–1694) was formally condemned for heretical teaching, a teaching that opposed the standard beliefs of the church. Pascal decided to defend Arnauld. He wrote a series of pamphlets that were supposed to look like letters between two friends, one in the city and one in the country or provinces. They came to be known as The Provincial Letters and poked fun at the Jesuits. They were very popular. The Jesuits tried without success to find the author. The wit, reason, eloquence, and humor of the letters made the Jesuits a laughingstock (object of ridicule).
The Pensées
When Pascal died in 1662, he left behind an unfinished theological work (relating to religious faith and practices), the Pensées. This was an apology, or defense, for Christianity. It was published eight years later by the Port Royal community in a thoroughly garbled and incoherent form. A reasonably authentic version first appeared in 1844. It deals with the great problems of Christian thought, faith versus reason, and free will.
The Pensées, unlike the Provincial Letters, were not highly edited and polished. The Letters give Pascal a place in literary history as the first of several great French writers practicing polite irony (humor in which words are used to mean the opposite of their true meaning) and satire (making fun of human faults and weakness). In contrast, some people think that the feeling of the Pensées makes it seem that it could almost have been written by another man. In them, reason is supposedly made to take second place to religion. Both books, however, are recognized as being among the great volumes in the history of religious thought.
Later mathematical and scientific work
Little is known of Pascal's personal life after his entry into Port Royal. Some of Pascal's scientific and mathematical works were not published until after his death. His "Treatise on the Equilibrium of Liquids," and his work on the links between theories involving liquids and gases, were enormously important in providing knowledge to develop air compressors, vacuum pumps, and hydraulic (run by the pressure created by forcing liquid through a small opening) elevators. Although he never wrote at great length on mathematics after entering Port Royal, the many short pieces that do survive are almost always concise and incisive.
The mathematical theory of probability (whether something is more likely to happen or not) made its first great step forward when Pascal and Pierre de Fermat (1601–1665) began writing to one another. They found that they both had come to similar conclusions independently. Pascal planned a treatise (a formal explanation of a theory) on the subject, but again only a fragment survived. It was published after his death. Pascal suffered increasingly from head pains after 1658. He died on August 19, 1662.
Pascal published many of his theorems without providing proofs as a challenge to other mathematicians. Solutions were found by some of the best mathematicians of the time, all rising to do their best by Pascal's leadership. The computer programming language "Pascal" is named after Blaise Pascal in honor of his early contributions to the science of computing. Thus, the influence of Blaise Pascal lives on today.

French mathematician, scientist, and philosopher
Blaise Pascal was an influential mathematical writer, a master of the French language, and a great religious philosopher (a person who seeks wisdom). He began making contributions to mathematics at a very young age. The computer programming language "Pascal" is named after him.
Young master of geometry
Blaise Pascal was born at Clermont-Ferrand, France, on June 19, 1623. His father, Étienne, was a civil servant and served as king's counselor. Blaise's mother, Antoinette, died in 1626. Blaise was three years old at the time and had two sisters, Gilberte and Jacqueline. In 1631 the family moved to Paris, France.
Blaise's father did not like the way school was taught at that time and instructed all three children at home himself. He placed special emphasis on learning Latin and Greek. He did not expose Blaise to geometry because he felt the topic was too enticing and attractive. Geometry is the branch of mathematics that deals with points, lines, angles, surfaces, and solids. He thought that if exposed to geometry and mathematics too soon, Blaise would abandon the study of classics.
This ban on mathematics merely served to make Blaise even more curious. On his own he experimented with geometrical figures. He invented his own names for geometrical terms because he had not been taught the standard terms. Some people believe that

Blaise was twelve years old when he started attending meetings of a mathematical academy with his father. Other scholars think that he did not attend the meetings until he was about sixteen. Whichever was the case, he was far younger than the adults who were there.
In 1640 the Pascal family moved to Rouen, France. Blaise was still taught mainly by his father. He worked very hard, but was frequently in poor health. During this time he developed a new theorem, or mathematical formula that can be proven, in geometry. He sometimes referred to this theorem as a "mystic hexagram." It was quite different from geometry that dealt with measured properties of figures. It was the foundation for an important, and, at the time, almost entirely undeveloped branch of mathematics.
In 1640, at age sixteen, Pascal wrote a book, Essay on Conics. It deals with the geometry of cones. He gave the mystic hexagram central importance in this book. At the age of nineteen, Pascal invented a calculating machine. It was able to add and subtract by having a person move a series of gears and cylinders. This was an early form of a computer.
Jansenists and Port Royal
In 1646 Pascal's father had an accident and was confined to his house. Some neighbors who were Jansenists came to visit him. The Jansenists were a religious group formed by Cornelius Jansen (1585–1638). Their beliefs were very different from the teachings of the Jesuits, who were the most influential group at the time. The Pascals began adopting the Jansenist beliefs. As a result, they received opposition from the local Jesuits.
After Étienne Pascal's death in 1651, Pascal's sister Jacqueline joined the Jansenists at their convent in Port Royal. Pascal continued to enjoy a more worldly life. He had a number of aristocratic (upper-class) and famous friends and money from his patrimony (inheritance) to support himself. In 1654, however, he completely converted to Jansenism, and joined his sister at the convent at Port Royal.
Provincial Letters
In 1655 the writer Antoine Arnauld (1612–1694) was formally condemned for heretical teaching, a teaching that opposed the standard beliefs of the church. Pascal decided to defend Arnauld. He wrote a series of pamphlets that were supposed to look like letters between two friends, one in the city and one in the country or provinces.

Facebook has turned up the heat on Google by purchasing content-sharing service FriendFeed, say industry watchers.
Many expected Google or even Twitter to buy the company, which has been praised for its "real-time" search engine.
This type of search is valuable because it lets you know what is happening right now on any given subject.
"Google look out, Facebook knows the real money is in real-time search," said respected blogger Robert Scoble.
"Google is the king of regular search. FriendFeed is the king of real-time search. This makes the coming battle over this issue much more interesting," Mr Scoble told the BBC.
Back in May, Google founder Larry Page admitted that the search giant had fallen behind other services like that of Twitter, which boasts nearly 45 million users worldwide.
"People really want to do stuff real time and I think they (Twitter) have done a great job.
"We've done a relatively poor job of doing things that work on a per second basis," Mr Page said at the time.
'Warning shot'
Many in Silicon Valley agree that this deal has changed the game.
"Facebook was unable to acquire Twitter so this is the next best option," said Ben Parr, associate editor of Mashable, a news blog covering social media.
"FriendFeed is well known for having some powerful and intelligent technology that allows users to aggregate everything they do online and do it all in real time.
 | WHAT DOES FRIENDFEED DO Friendfeed lets users bring together many of the accounts they have on social media and networking sites such as Facebook and Flickr Updates posted on those sites by a user and their friends are echoed on FriendFeed. A built in chat system lets FriendFeed users instantly comment or start a conversation about an update. These feeds of what friends are up to can be embedded in webpages or fed out to services such as Twitter. FriendFeed works with almost 60 sites including Delicious, Reddit, LinkedIn and NetVibes. |
"With this acquisition, Facebook is gunning directly not only at Twitter, but at Google. This is a warning shot to those two companies," Mr Parr told BBC News.
Mr Scoble noted that FriendFeed's real-time search could stretch back 18 months compared to a few days for Twitter.
Silicon Valley commentators have long regarded FriendFeed as an inspiration for many of Facebook's features.
These include the ability for users to import activities from third parties services like YouTube and Flickr to letting users comment or say they "like" something in another user's feed.
"FriendFeed has in effect been the R&D (research & development) department for Facebook for some time now," said Mr Scoble, who is one of the service's most popular users with nearly 46,000 subscribers.
"They have the best community technology out there and Facebook should continue to use them to try out new features and test them out before transferring them over to Facebook."
The deal
The purchase caught many in Silicon Valley by surprise, even though the two companies had been talking on and off for the past two years.
"This is an 11th hour deal," admitted FriendFeed co-founder Bret Taylor.
 Twitter sees itself as a new form of real-time communication |
Industry commentators had expected Google to make a bid for the company, especially given the fact that its founders all used to work there.
"FriendFeed accepts Facebook friend request" is how Mr Taylor described the buyout, in a tongue-in-cheek reference to how Facebook users ask one another to become part of their friend network.
He continued in a similar vein in his blog post.
"As my mom explained to me, when two companies love each other very much, they form a structured investment vehicle.
"Our companies share a common vision. Now we have the opportunity to bring many of the innovations we've developed at FriendFeed to Facebook's 250 million users around the world."
Facebook founder Mark Zuckerberg was equally complimentary.
"Since I first tried FriendFeed, I've admired their team for creating such a simple and elegant service for people to share information.
"As this shows, our culture continues to make Facebook a place where the best engineers come to build things quickly that lots of people will use."
As part of the agreement, all FriendFeed employees will join Facebook and the company's four founders will be given senior roles on the social networking site's engineering and product teams.
FriendFeed will continue as it is for the moment independently.
"Eventually, one way or another, it's hard to see FriendFeed as it stands now, continuing on," said MG Siegler of Silicon Valley news site Tech Crunch.
"Facebook will begin to take up too much of the FriendFeeders' time, and it will languish. It's sad, but that's the web. Not every service can flourish. There simply aren't enough users with enough time to use all of them."
