The famous saying of Newton, If I have been able to see further, it was only because I stood on the shoulders of giants, has influenced tons of people for the past century. Instead of taking it into account a way of being modest, some people really are convinced that without the influence of the past achievements, it is impossible for one to be successful, especially when we say so may Noble Prize goes to those who made adjustments to previous work. However, even though there exists certain reasonableness, it is not always the case and it is obviously too absolute if we say it impossible. Despite the fact that the claim is not completely right, we can not deny lots of brilliant works are actually delivered under the influenced of past talents in their fields of study. For example the without the development of telescope, astronomers would never get the chance to take a better look of otter space and consequently, they would not have defined solar system declaring that 9 moons, which was adjusted lately into 8, travel around sun. With no previous brilliance, it may cause them a really time to give different methods a try until they are able to take the best one and come to a convincing conclusion. While as long as the knowledge is provided to us, it will save us a great amount of time and sometimes it does take generations to get make one single progress, especially nowadays when science has been so developed and all the experiments become extremely complicated and difficult. It seems hard for anyone to carry on without applied to former experience. In some cases, though, people are not inspired by former works within their fields, instead, achievements of other field may help their break the ice during research and experiment. One of a mentionable example is how mechanical engineering related to discovery of biology knowledge: the function of bats laser pushed the invention of Radar, which has done human beings great help in military as well as navigation, not to mention how body construction of dragonfly inspire the inventor of fly. Sometimes people just got stuck in their field and were not be able to see the big picture. However, some other knowledge provided by talents achieved in other fields make offer a much more supporting evidence or even a suitable solution. Sometimes, innovation and a can-do sprit are what we need to accomplish certain contribution to a development. By mentioning Economics, I think it will make a perfect explanation as most of the models introduced by economists are based on lots of various hypothesis. And a pretty small adjustment of any of the hypothesis may make a totally different model and thus leads to an application that could be put into some other situations. Even though it may be some traces one could follow by going over past achievements, it is neither necessary nor helpful as it would always be so different. For instance, market situations of monopoly and duopoly can be so various that even though they share certain characteristic, it doesn't necessarily result in a similar profit opportunity or price setting scale. To wrap up, as far as I concerned, the statement about how accomplishments can be made based on past achievements make a lot of sense even though there are exceptions.
