The sheer technological and intellectual progress that we witnessed in the last century, along with the rise of the internet and large scale computing, is not reflected in the methods we use to write up our science. Little has changed since the time of Einstein. Not much has changed  since the time of Galileo either.
Authorea addresses specifically this challenge. Authorea papers live in the cloud, allowing large collaborations to write up and share science, easily integrating data, code and all the material needed to reproduce (and discuss) their results. Authorea can allow the long-awaited leap that will move the scientific paper in the 21st century.
