Andy Weir

Long before The Martian made readers cheer for a stranded botanist on Mars, Andy Weir was already running calculations in his head—about orbital mechanics, life support systems, and how many potatoes it would take to survive in space. He’s not just a writer who tells science fiction stories; he’s the kind of mind who reverse-engineers the science until fiction becomes startlingly plausible. That’s what sets his work apart in the genre: the thrill doesn’t come from alien invasions or distant galaxies, but from watching a lone character engineer their way out of a seemingly impossible situation—with duct tape, sarcasm, and a lot of math.

Weir grew up in California, the son of a particle physicist and an engineer, which perhaps explains his love for both scientific accuracy and problem-solving narratives. Before his breakout as a novelist, he worked as a software engineer—a career that shaped his methodical storytelling and precision with technical detail. He famously self-published The Martian chapter by chapter on his website, responding to reader feedback and refining the science as he went. When it hit Kindle, the book took off like a rocket, eventually becoming a New York Times bestseller and an Academy Award-nominated film starring Matt Damon.
