Small modular reactors, or SMRs, are the nuclear industry’s attempt to stop building gigantic one-off monsters and start building smaller, factory-made reactors that can be shipped, stacked, and deployed where big plants make no sense. Here’s how SMRs work, why they exist, where they’re showing up, and why the idea is both exciting and suspiciously complicated.

Nuclear fission sounds like the kind of thing you should only discuss in a bunker with three physicists and a lockbox. It is actually much simpler than that. Split a heavy atom, collect the heat, boil water, spin a turbine, make electricity. Here’s what nuclear fission is, why it exists, how it works, where it shows up in real life, and why it matters more right now than a lot of people realize.

Electromagnetic induction sounds like something trapped in a physics textbook. In reality, it is the reason generators produce electricity, transformers power the grid, wireless chargers work, and electric guitars scream. Here’s what electromagnetic induction is, how it works, and why it matters more than ever in an electrified world.
