摘要
We analyze the advent and development of eight scientific fields from their inception to maturity and map the 演化 of their 網絡s of collaboration over time, measured in terms of co-authorship of scientific papers. We show that as a field develops it undergoes a topological transition in its collaboration structure between a small disconnected graph to a much larger 網絡 where a giant connected component of collaboration appears. As a result, the number of edges and nodes in the largest component undergoes a transition between a small fraction of the total to a majority of all occurrences. These results relate to many qualitative observations of the 演化 of technology and discussions of the "structure of scientific r演化s". We analyze this qualitative change in 網絡 topology in terms of several quanti
