Where science meets the human story

We live in a scientifically dominated age. Nearly every aspect of modern life is shaped by science and technology, from medicine and space exploration to climate change, nuclear risk, and artificial intelligence.

Science is the source of our greatest hopes and our deepest fears. It drives progress, but it also raises profound questions about meaning, responsibility, and the future of civilization. In the 21st century, science cannot be separated from culture. The two are braided together, shaping our politics, our art, and our understanding of what it means to be human.

13.8 is a space for examining that relationship. Through essays and conversations, it explores the beauty, power, promise, and peril of science as a cultural force. If we want to understand our moment in history, this is where the inquiry begins.
