Ball Lightning
Ball lightning is a rare and unexplained phenomenon described as luminescent, spherical objects that vary from pea-sized to several meters in diameter. Though usually associated with thunderstorms, the observed phenomenon is reported to last considerably longer than the split-second flash of a lightning bolt, and is a phenomenon distinct from St. Elmo's fire. Some 19th-century reports describe balls that eventually explode and leave behind an odor of sulfur. Descriptions of ball lightning appear in a variety of accounts over the centuries and have received attention from scientists. An optical spectrum of what appears to have been a ball lightning event was published in January 2014 and included a video at high frame rate. Laboratory experiments have produced effects that are visually similar to reports of ball lightning, but how these relate to the supposed phenomenon remains unclear. Scientists have proposed a number of hypotheses to explain reports of ball lightning over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cannon
A cannon is a large- caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge, effective range, mobility, rate of fire, angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. In the modern era, the term ''cannon'' has fallen into decline, replaced by ''guns'' or ''artillery'', if not a more specific term such as howitzer or mortar, except for high-caliber automatic weapons firing bigger rounds than machine guns, called autocannons.

A Guide To The Scientific Knowledge Of Things Familiar
''A Guide to the Scientific Knowledge of Things Familiar'', also known as ''The Guide to Science'' or ''Brewer's Guide to Science'', is a book by Ebenezer Cobham Brewer presenting explanations for common phenomena. First published in the United Kingdom around 1840, the book is laid out in the style of a catechism and proved very popular. 47 editions were printed by 1905 in English alone and translations made into various other languages. A revised version was produced for the US market which was digitised and republished in 2005 as part of ''Making of America IV: the American voice, 1850–1877''. Although presented itself as an accurate science text, the book actually promotes religious ideas, including divine design. The popularity of ''The Guide to Science'' enabled Brewer to gather material for his ''Dictionary of Phrase and Fable'' which remains a classic reference work. Content The object of ''The Guide to Science'' was to present answers to over 2000 questions about comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Ac ...
