Ryūsei (signal Rocket)
A is a traditional Japanese signal rocket. Summary A ''ryūsei'' fuselage is made from either pine softwood or a section of bamboo, and it is propelled by the combustion of gunpowder. The particular type of gunpowder used in ''ryūsei'' is formulated to burn slowly. ''Ryūsei'' are believed to have been developed by reverse engineering primitive gunpowder rockets left behind by the defeated Yuan dynasty, Yuan armies after the Mongol invasions of Japan in the 13th century. However, there is another theory that ''ryūsei'' were invented locally by Japanese peasants. Because of this, they are sometimes called . In the 16th century, ''ryūsei'' rockets were used as smoke signals, and documents preserved at record the launch of a ''ryūsei'' in 1575. After the Second World War, bans on private possession of gunpowder nearly caused the extinction of ''ryūsei''. After many petitions, gunpowder for ''ryūsei'' was finally legalized again in 1972.

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technology In Medieval Japan
Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy.

Bo-hiya
is the Japanese version of the fire arrow. Bo-hiya were used in ancient Japan and by the samurai class of feudal Japan. History and description Fire arrows of some type have been used in Japan as far back as the 6th century where they are said to have been used during a military campaign in Korea. Bows (yumi) were used to launch these early fire arrows. In 10th-century China, gunpowder was used to launch fire arrows, and this type of fire arrow was used against the Japanese by Mongolian naval vessels in the 13th century. In 1543 the Japanese acquired matchlock technology from the Portuguese, and the resulting firearms developed by the Japanese led to new means of launching fire arrows. These rocket-type bo-hiya had the appearance of a thick arrow with large fins, a wood shaft and a metal tip; they resembled the Korean chongtong, an arrow-firing cannon. Bo-hiya were ignited by lighting a fuse made from incendiary waterproof rope which was wrapped around the shaft; when lit the ...

Climax (narrative)
The climax (from the Greek word ''κλῖμαξ'', meaning "staircase" and "ladder") or turning point of a narrative work is its point of highest tension and drama, or it is the time when the action starts during which the solution is given. The climax of a story is a literary element. Examples The punch line of a joke is an analogy for the climax of a fictional narrative, though the absence of any falling action is an essential difference, which may reflect the nature of humor as opposed to the nature of drama. In non-fictional narrative genres, even though the author does not have the same freedom to control the action and "plot" as in works of fiction, the selection of subject matter, degree of detail, and emphasis permit an author to create similar structures, i.e., to construct a dramatization. In the play '' Hippolytus'', by Greek playwright Euripides, the climax arrives when Phaedra hears Hippolytus react badly because of her love for him. That is the moment that A ...

Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire(bushfires in Australia, in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...
