Arena Physica: Building Electromagnetic Superintelligence

Language models aren't the only path to intelligence. For physics, the primitive is fields.In this episode of the Mission Matters Podcast, Maggie Gray and Akhil Iyer sit down with Pratap Ranade, CEO & Co-Founder of Arena Physica, to discuss how he and his team are building electromagnetic superintelligence. Pratap breaks down Atlas, an agentic platform that pairs non-deterministic AI agents with deterministic physics and simulation models, and Heaviside, the first foundation model for RF design, trained on electromagnetic fields instead of words.They cover why hardware's software-defined future makes electromagnetism matter more than ever, how Heaviside hit its "GPT-1 moment" with fully autonomous RF design, how Arena generates training data in a field with none publicly available, the pivot that deleted a double-digit-million revenue stream, and Pratap's vision for a new kind of Bell Labs.As always, please let us know what you think. And please reach out if you or anyone you know is building at the intersection of technology and national security.
