Title          
Harvard Biovisions - The Inner Life of a Cell 
   
 
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...

Title          
Marble displacer Stirling Engine 
   
 
Abstract    

5 rolling marbles act as the displacer in this engine. The rigid connection between the piston and conrod is what tips the test tube, rolling the marbles.

Model of stirling engine realized by a syringe and a test-tube.

In the family of heat engines, 'Stirling engine' defines a closed-cycle regenerative hot air engine (or other permanent gas) engine, though the term is often used incorrectly to refer generically to a much wider range of hot air engine types. In this context, "closed-cycle" means that the working fluid is permanently contained within the system, whereas "open-cycle" engines such as internal combustion engine and some st...

Title          
Smoke flow visualization over an Airfoil 
   
 
Abstract    

In general, flow visualization is an experimental means of examining the flow pattern around a body or over its surface. The flow is "visualized" by introducing dye, smoke or pigment to the flow in the area under investigation. The primary advantage of such a method is the ability to provide a description of a flow over a model without complicated data reduction and analysis.

Title          
Most Influential Masters Thesis 
   
 
Abstract    

Claude Elwood Shannon (April 30, 1916 – February 24, 2001) was an American mathematician, electronic engineer, and cryptographer known as "the father of information theory". Shannon is famous for having founded information theory with one landmark paper published in 1948. But he is also credited with founding both digital computer and digital circuit design theory in 1937, when, as a 21-year-old master's student at MIT, he wrote a thesis demonstrating that electrical application of Boolean algebra could construct and resolve any logical, numerical relationship. It has been claimed that this was the most important master's thesis of all time. Shannon contributed to the field of cryptanalysis during World War II and afterwards, including basic work on code breaking.

The Miracle in Human Brain 
   
 
Abstract    

How your brain works, amazing connections between billions of neuron cells.

In animals, the brain (enkephale) (Greek for "in the skull"), is the control center of the central nervous system, responsible for behavior. The brain is located in the head, protected by the skull and close to the primary sensory apparatus of vision, hearing, equilibrioception (balance), sense of taste, and olfaction (smell). While all

Title          
How RSS Feeds Work 
   
 
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...

Lockheed Morphing UAV 
   
 
Abstract    

High performance jet fighters have used a variety of morphing mechanisms in the past such as variable-sweep wings and fowler flaps to expand the flight envelope. Lockheed Martin (NYSELMT) is a leading multinational aerospace manufacturer and advanced technology company formed in 1995 by the merger of Lockheed Corporation with Martin Marietta. It is headq...

Abstract    
Venkatraman "Venki" Ramakrishnan (Tamil: வெங்கட்ராமன் ராமகிருஷ்ணன்; born 1952 in Chidambaram, Tamil Nadu, India) is a structural biologist at the MRC Laboratory of Molecular Biology in Cambridge, England.[1] He shared the 2009 Nobel Prize in Chemistry with Thomas A. Steitz and Ada E. Yonath "for studies of the structure and function of the ribosome".[2] Venkatraman Ramakrishnan was born in Chidambaram in Cuddalore district of Tamil Nadu, India.[3] He moved to Baroda (Vadodara) in Gujarat state at the age of three, where he had his schooling, except for spending 196061 in Adelaide, Australia. Following his Pre-Science at the Maharaja Sayajirao University of Baroda, he did his undergraduate studies in the same university on a National Science Talent Scholarship, graduating with a B.Sc. in Physics in 1971. In a January 2010 lecture at the Indian Institute of Science, he revealed that he failed to get a seat at any of the colleges of the Indian Institutes of Technology, and Christian Medical College, Vellore, Tamil Nadu.[4] Immediately after graduation he moved to the U.S.A., where ...

Title          
Theory of Lift Generation - Airfoil 
   
 
Abstract    

There have been varies theories explaining the production of lift by an airfoil. Interestingly, many rather most of these have been misconceived and hence are false. This lists the major theories proposed and the drawbacks they suffer finally leading to a correct acceptable theory.

A fluid flowing past the surface of a body exerts a force on it. Lift is defined to be the component of this force which is perpendicular to the oncoming flow direction.[1] It contrasts with the drag force, which is defined to be the component of the fluid-dynamic force
