Yale University is a private university in New Haven, Connecticut. Founded in 1701 as the Collegiate School, Yale is the third-oldest institution of higher education in the United States and is a member of the Ivy League. Particularly well-known are its undergraduate school, Yale College, and the Yale Law School, each of which has produced a number of U.S. presidents and foreign heads of state. In 1861, the Graduate School of Arts and Sciences became the first U.S. school to award the Ph.D. degree. Also notable is the Yale School of Drama which has produced many prominent Hollywood and Broadway actors, as well as the art, forestry and environment, music, medical, management and architecture schools, each of which is often cited as among the finest in its field. |

Abstract |
A non-Newtonian fluid is a fluid in which the viscosity changes with the applied strain rate. As a result, non-Newtonian fluids may not have a well-defined viscosity.
Although the concept of viscosity is commonly used to characterize a material, it can be inadequate to describe the mechanical behavior of a substance, particularly non-Newtonian fluids. They are best studied through several other rheological properties which relate the relations between the stress and strain tensors under many different flow conditions, such as oscillatory shear, or extensional flow which are measured using different devices or rheometers. The rheological properties are better studied using tensor-valued constitutive equations, which are common in the field of continuum mechanics.
An inexpensive, non-toxic sample of a non-Newtonian fluid sometimes known as oobleck can be made very easily by adding corn starch (cornflour) to a cup of water. Add the starch in small portions and stir it in slowly. When the suspension nears the critical concentration - becoming like single cream (light cream) in consistency - the so called "shear thickening" property of this non-Newtonian fluid becomes apparent. The application of force - f... |

He received the Salem Prize in 2000, the Bôcher Prize in 2002, and the Clay Research Award in 2003, for his contributions to analysis including work on the Kakeya conjecture and wave maps. In 2005 he received the American Mathematical Society's Levi L. Conant Prize with Allen Knutson, and in 2006 he was awarded the SASTRA Ramanujan Prize.
In 2004, Ben Green and Tao released a preprint proving what is now known as the Green-Tao theorem. This theorem states that there are arbitrarily long arithmetic progressions of prime numbers. The New York Times described it this way:[9][10]
“ In 2004, Dr. Tao, along with Ben Green, a mathematician now at the University of Cambridge in England, solved a problem related to the Twin Prime Conjecture by looking at prime number progressions — series of numbers equally spaced. (For example, 3, 7 and 11 constitute a progression of prime numbers with a spacing of 4; the next number in the sequence, 15, is not prime.) Dr. Tao and Dr. Green proved that it is always possible to find, somewhere in the infinity of integers, a progression of prime numbers of equal spacing and any length. ”
For this and other work, he was awarded the ... |

Abstract |

MATLAB is a numerical computing environment and programming language. Created by The MathWorks, MATLAB allows easy matrix manipulation, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs in other languages. Although it specializes in numerical computing, an optional toolbox interfaces with the Maple symbolic engine, allowing it to be part of a full computer algebra system.
Short for "matrix laboratory", MATLAB was invented in the late 1970s by Cleve Moler, then chairman of the computer science department at the University of New Mexico. He designed it to give his students access to LINPACK and EISPACK without having to learn Fortran. It soon spread to other universities and found a strong audience within the applied mathematics community. Jack Little, an engineer, was exposed to it during a visit Moler made to Stanford University in 1983. Recognizing its commercial potential, he joined with Moler and Steve Bangert. They rewrote MATLAB in C and founded The MathWorks in 1984 to continue its development. These rewritten libraries were known as JACKPAC.
MATLAB was first adopted by control design engineers, Lit... |

Abstract |
|
Autodesk Revit is architectural BIM software for Microsoft Windows, currently developed by Autodesk, which allows the user to design with parametric modeling and drafting elements. BIM is a new Computer Aided Design (CAD) paradigm that allows for intelligent, 3D and parametric object-based design. In this way, Revit provides full bi-directional associativity. A change anywhere is a change everywhere, instantly, with no user interaction to manually update any view. A BIM model contains the buildings full life cycle, from concept to construction to decommissioning. This is made possible by Revit's underlying relational database architecture which its creators call the parametric change engine.
Autodesk purchased the Massachusetts-based Revit Technology Corporation for $133 million US in 2002.[1] The latest released version is Revit Architecture 2008 (April 2007) and AutoCAD Revit Architecture Suite 2008 (which includes AutoCAD 2008 32-bit & 64-bit).
Revit is a single file database that can be shared among multiple users. Plans, sections, elevations and schedules are all interconnected, and if a user makes a change in one view, the other views are automatically updated. Thus, Revit d... |

Abstract |
Fantastic animation of the inside of a cell from Harvard Biovisions.Harvard University (incorporated as The President and Fellows of Harvard College) is a private university in Cambridge, Massachusetts, USA and a member of the Ivy League. Founded in 1636 by the Massachusetts Legislature,[2] Harvard is the oldest institution of higher learning in the United States, as well as the first and oldest corporation in the Americas.[4]
Initially referred to simply as "the new college", the institution was named Harvard College on March 13, 1639, after its first principal donor, a young clergyman named John Harvard. A graduate of Emmanuel College, Cambridge in England, John Harvard bequeathed about four hundred books in his will to form the basis of the college library collection, along with half his personal wealth worth several hundred pounds. The earliest known official reference to Harvard as a "university" rather than a "college" occurred in the new Massachusetts Constitution of 1780.
In his 1869-1909 tenure as Harvard president, Charles William Eliot radically transformed Harvard into the pattern of the modern research university. Eliot's reforms included elective courses, small classes, and entrance exam... |

CEV NASA space launch rocket trip to moon

Abstract |
The Draft Statement of Work for the CEV was issued by NASA on December 9, 2004, and slightly more than one month later, on January 21, 2005, NASA issued a Draft Request For Proposal. The Final RFP was issued on March 1, 2005,[2] with the potential bidders being asked to answer by May 2, 2005.
NASA had planned to have a suborbital or an Earth orbit fly-off called Flight Application of Spacecraft Technologies (FAST) between two teams' CEV designs before September 1, 2008. However, in order to permit an earlier date for the start of CEV operations, Administrator Griffin had indicated that NASA would select one contractor for the CEV in 2006. From his perspective, this would both help eliminate the currently planned four-year gap between the retirement of the Shuttle in 2010 and the first manned flight of the CEV in 2014 (by allowing the CEV to fly earlier), and save over $1 billion for use in CEV development.[3]
On June 13, 2005, NASA announced the selection of two consortia, Lockheed Martin Corp. and the team of Northrop Grumman Corp. and The Boeing Co. for further CEV development work.[4] Each team had received a US$28 million contract to come up with a complete design for the CEV and its launch vehicle un... |

Abstract |
RSS is a family of Web feed formats used to publish frequently updated content such as blog entries, news headlines or podcasts. An RSS document, which is called a "feed," "web feed," or "channel," contains either a summary of content from an associated web site or the full text. RSS makes it possible for people to keep up with their favorite web sites in an automated manner that's easier than checking them manually.
RSS content can be read using software called an "RSS reader," "feed reader" or an "aggregator." The user subscribes to a feed by entering the feed's link into the reader or by clicking an RSS icon in a browser that initiates the subscription process. The reader checks the user's subscribed feeds regularly for new content, downloading any updates that it finds.
The initials "RSS" are used to refer to the following formats:
Really Simple Syndication (RSS 2.0)
RDF Site Summary (RSS 1.0 and RSS 0.90)
Rich Site Summary (RSS 0.91)
RSS formats are specified using XML, a generic specification for the creation of data formats.
The RSS formats were preceded by several attempts at syndication that did not achieve widespread popularity. The basic... |

Abstract |
Yale traces its beginnings to "An Act for Liberty to Erect a Collegiate School" passed by the General Court of the Colony of Connecticut and dated October 9, 1701. Soon thereafter, a group of ten Congregationalist ministers led by James Pierpont, all of whom were Harvard alumni (Harvard having been the only college in North America when they were school-aged), met in Branford, Connecticut, to pool their books to form the school's first library.[11] The group is now known as "The Founders." Yale was founded to train ministers.
Originally called the Collegiate School, the institution opened in the home of its first rector, Abraham Pierson, in Killingworth (now Clinton). It later moved to Saybrook, and then Wethersfield. In 1718, the college moved to New Haven, Connecticut, where it remains to this day.[citations needed]
In the meanwhile, a rift was forming at Harvard between its sixth president Increase Mather (Harvard A.B., 1656) and the rest of the Harvard clergy, which Mather viewed as increasingly liberal, ecclesiastically lax, and overly broad in Church polity. The relationship worsened after Mather resigned, and the administration repeatedly rejected his son and ideological colleag... |
