Advances in communication make science easier to practice today compared to 100 years ago. Throughout history, there are examples of independent scientists reaching the same breakthroughs, such as calculus and the theory of evolution, nearly simultaneously. While this sometimes happens today, collaborations are much easier since the advent of the Internet, as files and data can be shared almost instantaneously. And open-access publishers of scientific journals like Public Library of Science (PLoS) make peer-reviewed scientific articles available immediately after publication, free of charge. Overall, this expedited exchange of information makes the community significantly more productive.
