Leah Huggins (Cummings) Block 4 Discussion questions Chapter 13 Arthur Steinhaus is concerned that a mixed sports program for men and women develops "social benefits and related things. Basically, he thinks women are weak, and men will not grow if they compete with women. During the Second World War, sports competition became more popular than physical education. "Because the competition in which all the winners participate can be a difference between life and death on the battlefield." It is necessary to train the army. In order to win not only physical education but also competition with enemies. Chapter 14 The popularity of basketball for men and ladies can be attributed to the inventor of the game, Dr. James A. Naismith. This game is fun as well as playing indoors in winter, so it will soon succeed and the news spread quickly. Women have traditionally not recommended participation in serious sports competitions because early sports advocates thought they had established masculinity - women should not be irrelevant. Chapter 15 Pierre de Freddie, Baron de Coubertin is a French educator and historian and the founder of the International Olympic Committee. He is regarded as the father of the modern Olympic Games. The subject he seems to be most interested in is education, and his research focuses on the role of physical education and physical education in school education. In 1883, he visited

For the first time in the UK, Thomas Arnold studied physical education at the rugby school. Coubertin attributed these methods to the expansion of the British power of the 19th century, claiming its use in French institutions. Incorporating physical education into the curriculum of a French school will be a continuing pursuit and a passion for the Coubertin. As a historian and educational thinker, Coubertin made romantic ancient Greece. Therefore, when he began to develop his sports theory, he saw an example set by the Athens Stadium concept, which is a training facility naturally encouraging both physical and intellectual development. In these stadiums, he saw the so-called triple unification, meaning between theoretical work and practical work between ancient and youth, between disciplines, and between different types of people . Coubertin insisted on these concepts and this triple unity was built into the Olympic Games advocated by the school by Coubertin, centered around several ideals of sports. He believes that the early Ancient Olympics promoted competition among amateur players and saw its value more than professional athletes. The ancient custom of the sacred Armistice related to the Olympic Games may have a contemporary meaning so that the Olympic Games will play a role in promoting peace.

Using the above image, the block contains "hash" in block 3. That is, if you change the contents of block 3, the hash value of block 3 changes (stored in block 4), the hash value of block 4 also changes. This means that each subsequent block in the chain is no longer linked and the chain is disconnected. Therefore, the network does not accept this change. Public networks such as Bitcoin and Ethernet are widely known. With computers and intuitive instructions, anyone can connect as a node to these networks. The encryption currency tends to be hosted on the public network, and it is possible to conduct global transactions between individuals.

Block chains are changed by design tolerance. Part of the security of the block chain is to ensure that links between blocks are not tampered with. Therefore, the hash before block # 3 is actually equivalent to the hash of block # 2. This is what I checked in with the "isChainValid" method. Another part of the protected block chain is to make sure that the data in the block after creating the block has not changed. For example, if someone tries to change who completed the transaction in the block, you need to prevent this in order to ensure security. If the data in the block has been tampered with, since the data is an input to the hash function, the hash of the block also changes. Changing the hash value is also taken into account in the "isChainValid" method to see if the data has changed since the block was created.
