Networks measure interactions. They emerge in the spread of epidemics, in the firing of neurons in the brain, in the food webs that sustain ecosystems, and in the flow of information online. We move through networks every day, though most remain unseen.

Network science has become a vibrant field that draws on mathematics, computing, biology, and the social sciences, offering fresh ways to understand the systems around us. Join me in exploring these networks of dots and lines, and discover how once you see them, the world never looks the same.
