🔬 Science & Technology – Evolvixa Academy

Science & Tech is one of those subjects that confuses a lot of students — not because it’s hard, but because no one knows exactly how to study it. “Do I need to read old NCERTs? Or just follow PIB? Is this current affairs or static?” These are the kind of questions I get every week. And honestly, the confusion makes sense — because this section doesn’t follow a fixed syllabus the way Polity or History does.

UPSC wants you to understand tech that’s relevant. Not how a satellite works, but why it’s being used for flood mapping. Not just what CRISPR is, but how it might change Indian agriculture. You don’t need to be a scientist. But you do need to think like a policymaker — someone who asks: “How does this help people on the ground?”

I’ve seen students drown in terminology — nanotech, biotech, robotics, AI, green hydrogen, 5G, space missions… and still blank out when asked to explain the societal impact. That’s the gap. That’s what we’re here to fix.

This section covers the core areas — defense tech, energy, space, health innovations, ICT, and emerging tech — but with examples, use cases, and context. No jargon overload. No overkill. Just what you need to write a good answer and understand what’s actually going on.

If you’ve been scared of Science & Tech because you’re not from a science background — you’re not alone. And you don’t need to fear it. UPSC isn’t testing your ability to solve equations. It’s testing your ability to make sense of what’s happening around you. Let’s do that, step by step. Simple, clear, useful. That’s the goal here.
