Welcome!

We are an encyclopedia project, and more.

We are a different sort of Web 2.0 project:

We aim at credibility and quality, not just quantity.
Both the general public and credentialed experts are encouraged to get involved.
We use our real names, not pseudonyms.
We're collegial.

We have added over 3,700 articles (and many subpages) since November 2006.
Read our first year progress report and press release.

New authors and editors welcome!
A human being will respond usually within a few hours.

Article of the Week [ about ]

Chemistry is the science of materials. Chemists consider that all of the materials in the world are matter, primarily made up of atoms. The combination of at least two atoms connected by a chemical bond leads to molecules. Ions are derived from atoms or molecules by loss or gain of one or more electrons leading to charged particles. Salts are composed of cations (positively charged ions) and anions (negatively charged ions), so that the substance or material is neutrally charged (without net charge). Chemists use their view of matter at the atomic to molecular level to explain how different materials interact, and how they change under varying conditions. [more...]

New Draft of the Week [ about ]

Augustin-Louis Cauchy (Paris, August 21, 1789 – Sceaux, May 23, 1857) was one of the most prominent mathematicians of the first half of the nineteenth century. He was the first to give a rigorous basis to the concept of limit. His criterion for the convergence of sequences defines sequences that are now known as Cauchy sequences. This notion has led to the fundamental mathematical concept of a complete space. The Cauchy condition for the convergence of series can be found in any present-day textbook on calculus. Probably Cauchy is most famous for his singlehanded development of complex function theory, with Cauchy's residue theorem as the fundamental result.[more...]

-'''[[Albert Gallatin]]''' (born in [[Geneva]], [[Switzerland]], on Jan. 29, 1761; died, August 12, 1849 in Astoria, New York) was an American politician, statesman, diplomat and linguist who served as the United States [[Secretary of the Treasury]] from 1801 to 1814.

-Gallatin was born into an old aristocratic family.  He was orphaned at age nine but well cared for by his extended family.  While a student at the elite Geneva Academy, Gallatin read deeply in philosophy of Jean-Jacques Rousseau and the French Physiocrats; he became dissatisfied with the traditionalism of Geneva.  <font size=1>[[Albert Gallatin|['''more...''']]]</font>

-The '''[[B-17]]''', nicknamed the "Flying Fortress" was a heavy bomber that was the workhorse, along with the [[B-24]], of America's strategic bombing of Germany in World War II.  The Army Air Forces (AAF) considered the B-17 the perfect embodiment of its strategic bombing doctrine because of its long-range, its ability to defend itself, and its highly accurate Norden bomb-sight.  The [[Boeing]] corporation built 6,981 B-17s in various models, and another 5,745 were built under a nationwide collaborative effort by Douglas and Lockheed (Vega).  They were mainly deployed in Europe, flying with the 8th Air Force in England and the 15th Air Force in the Mediterranean. Their mission was strategic bombing. <font size=1>[[B-17|['''more...''']]]</font>
