For a brief time in world history, China dominated maritime exploration. Even though quite unintentionally, a previous century’s invention of the magnetic compass played a pivotal and facilitating role and provided Chinese sailors a two-hundred-year head start over their European counterparts. However, it was not until blending those navigational advancements of the day, together with nautical technologies of shipbuilding architecture and propulsion found China readily thrust to the forefront. Emperor Yongle of the Ming Dynasty desired to leverage those technologies to construct an immense armada attesting to the court’s military prowess. Supported by a backdrop of politically favorable winds and a generous endowment, the Emperor commissioned the undertaking of explorations to an experienced Admiral named Zheng He.
The Satllite Archeology can find where you are on the earth from your phone or any technology that you
Although the report released by Lawson provided insight about earthquake occurrence, it cannot help scientists and geologists to accurately predict when the next earthquake will occur. However, with advanced monitoring systems and computing power may help in better preparation of future earthquakes. The 1906 San Francisco earthquake brought geologists and scientists together and led to an understanding of earthquakes; how they occur, why they occur and how the world can prevent and manage such disasters in
The casualty rate of a flamethrower during World War 1 was 82%, which is really high considering only some were intended to kill. The flamethrower uses pressurized air and burning oil to shoot out a flame that can reach up to 60 feet. Some even used coal and nitrogen. The flamethrower has multiple uses. Some are to inflict psychological damage to the enemy to scare them off.
Many groups of people without prior experience or training packed gunpowder kegs in the buildings and ignited a fuse. In a short while, the explosions began causing injury to people and blazing debris which in turn ignited the adjacent buildings. At this point, Damrell was forced to stop the use of gunpowder to quench the fire (Sammarco,
In the 904AD the army used the gunpowder in the form of crude rockets [1]. They would insert small stone cannonballs inside the bamboo tree tubes and blast them out by igniting the gunpowder at the end. The Chinese emperors had tried to keep the discovery of gunpowder as a secret weapon, but before the 1100s AD their secret spread to other nations such as the Islamic Empire and the Roman Empire. The knowledge about gunpowder spread out very fast throughout the word in the 13th century due to the Mongol Conquests.
Many celebratory firework shows were coupled with dancers in the streets who wore different costumes and moved through the clouds of colored smoke. The fact that gunpowder had such explosive power proved to enhance the Chinese economy both in the Tang Dynasty and even more so into the Song Dynasty because it allowed for an increase in their copper supply. The Song Dynasty marked the turning point in which the Chinese realized that gunpowder would make a good weapon against their enemies. The Song Dynasty’s military created numerous gunpowder devices that they aimed towards their primary enemy, the Mongols. Some of the weapons they invented included the flamethrower, hand held cannons, and hand grenades.
Gunpowder is made up of saltpeter- a common name for the oxidizing agent potassium nitrate- sulfur and charcoal (Heather Whipps, 2008). When the Chinese scientists first mixed the ingredients together it resulted in smoke and flames, causing their hands and faces to burn (Heather Whipps, 2008). One of the first
So until they discover something else that is better gunpowder will still be used for many years to
Without the Mongolian’s maps or technological advances, such as the compass, Marco Polo would have never came to Asia seeking the
While some of the countries that earthquakes widely affect are industrialized and can afford to have technology that can track and predict earthquakes, many of the less developed ones are left to fend for themselves and will likely suffer greatly from the devastating effects of these natural disasters. Although industrialized, Mexico is one of the most detrimental locations for an earthquake to occur. According to SkyMet Weather, “it is situated atop three seismic plates namely, Cocos plate, Pacific plate and the North American plate” (SkyMet Weather, 9). This inevitably leads to disastrous casualties almost every time that one occurs in that area. A less-developed country, Pakistan, is likely to have little to no warning that these earthquakes may be arriving due to a lack of technology.
By the 13th century, gunpowder was being used extensively by Chinese and Mongol forces. Many credit the Mongol’s invasions of Persia and eastern Europe in the 13th century as the catalyst for which the invention of gunpowder was able to spread so quickly. The Moors used gunpowder cannons during the siege of Seville as early as 1248 A.D. By the 14th century Edward I, the king of England and the 'Hammer of the Scots', used cannons during battles against the ‘Scots’ while taking control of Scotland. During the 100 years war, both the English and the French used cannons against each-other.
What they can do is make use of seismometers that passively record ground motion in the form of seismic waves. Improving software and telemetry from a network, seismologists on the West Coast of the United States are testing earthquake early warning. Earthquake early warning systems are the best tool that seismologists have to forewarn the public when an earthquake will arrive, but only after the fault has slipped. When a fault slips, two types of waves are generated, the primary wave and the secondary wave.
This paper talks about Chinese invention of Gun powder during the 9th century and how it evolved to other countries and leads to further inventions. Gunpowder is the first chemical
MAGNETIC COMPASS Compasses work by using magnets. The magnet inside them is drawn to the Earth’s magnetic field and the magnetic poles. The magnetic compass brought lots of change about for medieval Europe. It allowed more trade and the exploration of new places.
