Albert-László Barabási is a distinguished professor at Northeastern University in Boston. In this episode, he tells us how he established the field of network science. He explains the expert’s fallacy and why it’s time to move to another field once you become afraid to break things. He tells about his strategies to select research projects with his students, and that the science only really starts after the first draft has been written. He also tells us how the crucial skill to make discoveries is to sense which idea’s time has come, and how to move into a field when you think that you can bring something all of your own to the table.For more information on Night Science, visit https://www.biomedcentral.com/collections/night-science .
