Resently, there is a statement that in any field of endeavor, it is impossible to make a significant contribution without first being strongly influenced by past achievements within that field. The new contributions can be influenced by original success from my point of view with a positive impact or negative impact, and can not be avoided influence of previous contribution.First of  all, the old contribution in a field can gives a helpful effect to later people who makes new discovery or inventions there. The people later can involve the methods to achieve their study, accerlerating the degreed of their reaserches, increasing the possiblity of them to be successful.  And maybe it is able for us to avoid much failures that had been suffered from the earlier scientists and had been conluded that they were not right in these ways. Therefore, the new contributions of later scientists can be discovered or invtented sooner rather than losing by the passed falses experienced by early people. For instance,  the famous scientist Newton proposed the gravity law based on the theories of Galieo and Descartes, who promoted his study on gravity law. If there were no Galieo and Descartes at that time, then we may ask the law would come out so soon to the world. So we can not ignore the positive influence of predecessors who made great achievement in that field giving an impetus to later ones.However, the opposite effect of predecessors' accomplishment will have effect on our later people in their subjects. Since we are not capable to prove that the past contributions are always right, we may be misleaded by the past contributions sometimes. When we are affected by false opinions without conciousness, it is hard for us to reach the success and the falures results from a directed effect on false theories. Even though you find it is wrong, you may have spend much labor on it. Furthermore, sometimes the older contibutions will inhibit and against new dicoveries, as a great powerful to stand against the new achievements that are truth or real. For example, the people, Copernicus, Galileo found that the Earth was not the center of the univer and the Sun was not statical which was opposite to the mainstream view of astronomy, and they constantly persecuted by religious people. This is the bad effect of old accomplishment to influence later people.In conlusion, many factors confirm that it is impossible to make a significant contribution without first being strongly influenced by past achievements within that field,In any field of endeavor
