The Process of Battleship In 19th And 20th Century

                                                The Process of Battleship

     Every country wants to become the superpower of the world, and it all depends on the military strength. In the 19th century, the controlling force of the sea was extremely important to the race. And that's why British which were the leader of sea force started making Dreadnought.

     The international battle ship arms-race began in 1890s, and Dreadnought was developed during that period. Dreadnoughts are a big jump in battle ship-arm, and they are extremely different from the previous battle ships. "All-big-gun" is one of Dreadnoughts' features. The previous battle ships have many different sizes of guns which included 12, 4.7 and 7.5 inches. But later "all-big-gun" was accomplished in Dreadnought because heavy guns offer advantages in both fire power and fire control. Propulsion of Dreadnoughts is also different from previous battle ships. Although the first generation of Dreadnoughts was propelled by steam engines which was used in the previous battle ship also, it changed into a geared turbine later because the battle ship propelled by a steam engine was very slow and not efficient(ship short range) at all. The fuel of Dreadnoughts reached a big improvement too. Previous battle ships were fueled by coals which had many disadvantages, such as labor-intense, inefficiency and production of black smoke which can give away the position of the fleet. So they changed they changed Dreadnoughts into oil-fired which can reduce smoke, make the ship less visible, no stoker, and more efficiency because of the high thermal content. The new battle ship Dreadnought is better, faster and stronger.

Criticism Makes Us Better

      

     Most people don't like to accept criticism and say they'll do better if there isn't any criticism because they feel embarrassed by criticism. But the truth is we must need criticism and it's the most efficient way to make us better. It's like awful medicines, but the patient must take those.

     The criticism is like one measurement which can help people know how good he is and help him reach more improvements. Mr. Jobs who is one of the greatest inventors in this century likes criticizing a lot. He is either highly criticized own his own designs or his employs'. They did hundreds different designs before iPhone came out. He always criticizes his employs' designs extremely directly without euphemisms because he thinks it's the fastest way to improve the designs. Later, the success of iDevices proves the necessity of criticism. Great success needs great criticism, and the more criticism, the better it'll be.

     Many people don't feel happy when they receive criticism, but they'll appreciate about that. They know the people who criticize them are trying to help them and make them reach more success. There is always a group of critics in American Idols which is a talent show and help people even more talented. People who go to the competition are extremely good at their areas, but no one is perfect. All of them need to fetch more improvements in some specific skills. And that's the reason why the critics are there. In other words, criticism does help people know better about themselves and become better.

     People need criticism even they already reach great success because that's the way to become better and keep success. In Tang Dynasty, emperor Taizong who is one of the greatest emperors in China's history was eager for criticism. He was full of knowledge and wisdom, but he always asked for criticism for his deploys, especially Weizheng. Weizheng always criticized emperor Taizong directly without much euphemism, and makes the emperor Taizong embarrassed. However, emperor Taizong never punished him, but gave him higher officer instead because the emperor Taizong knew that good advice is harsh to the ear.

     In conclusion, we need criticism and we need to know criticism is the most efficient way to make us better. Although criticism makes us embarrassed, but we'll feel extremely happy when we become better from criticism. It's time to wake up, and find the criticism of us now.
