Hundreds of Interesting Things to Learn About

The world around us is interesting enough on its own and we don’t have to look far. At Nerdish, we simply take familiar things and ask: why does this work this way? when did this start? how did nobody tell us this before?

Some of our best articles were inspired by our own children. “Why do cats choose to live with humans?” “When were traffic lights invented?” These sound like simple questions, but once you start digging, you can’t stop.

We believe this is exactly what keeps curiosity alive: not chasing exotic topics, but finding the surprising depth in things you see every day. It’s also why Nerdish resonates with people across every continent — because curiosity about the world around us is something we all share.

And there’s a deeper benefit too. Exploring a wide range of topics builds general knowledge: the foundation that quietly connects ideas across different fields. Research shows that people with broad general knowledge think more flexibly, spot unexpected connections, and approach problems more creatively. This is one more reason why we encourage everyone to have Nerdish on their device. It’s not just entertaining — it literally makes you smarter in ways you didn’t expect.

The easiest way is to start with what already makes you stop scrolling. A headline that caught your eye, a question someone asked that you couldn’t answer, something you saw and thought “huh, I never actually knew how that works.”

Curiosity doesn’t need a plan — it needs a starting point. At Nerdish, we organize topics across science, history, psychology, art, technology, and daily life, so you can follow whatever pulls you in that moment. Some people stick to one area. Others jump between completely different subjects and love the variety.

Both approaches work. The only wrong move is waiting until you feel “ready” to learn — because that moment rarely comes on its own.

And your learning journey doesn’t have to stop with Nerdish. Think of the app as a starting point — a place to discover what genuinely interests you. Once a topic clicks, you can always go deeper: a specialized course, a book, a documentary. That’s exactly how it should work.

But the most important thing is to keep curiosity alive. Ask questions. Look things up. With the tools we have today, finding answers has never been easier. Do this consistently — day by day, topic by topic — and something remarkable happens: you build a unique body of knowledge that is entirely your own. Things you’re genuinely interested in. Things you might already know better than most people around you.

This is more common than you think — and it’s usually not a lack of curiosity, but a lack of exposure.

When we spend most of our time inside the same routines, the same feeds, the same conversations, our curiosity doesn’t disappear — it just doesn’t get triggered. It needs new input to wake up.

The simplest thing you can do is start somewhere random. Pick a topic you know almost nothing about: ancient civilizations, how vaccines work, why certain music makes you emotional and spend ten minutes with it. You don’t have to commit or love it. You’re just looking for that small spark of “oh, that’s actually interesting.”

This is exactly where Nerdish helps. With hundreds of topics across completely different fields, it’s designed for exploration rather than commitment. You’re not signing up for a course — you’re browsing, following what catches your eye, and giving yourself permission to be surprised.

At Nerdish, we’ve seen this happen thousands of times. Someone opens an article about the history of tea with zero expectations  and ends up reading about trade routes, colonial history, and the economics of caffeine. One topic leads to another. That’s just how curiosity works.

So if you don’t know what you’re curious about yet — start anywhere. The rest will follow.

Honestly, both work, and the right answer depends on where you are in your curiosity journey.

If you’re just starting out, exploring broadly is almost always the better move. Exposure to many different subjects helps you understand what genuinely excites you. It also builds general knowledge that makes you a more creative and flexible thinker — because the most unexpected connections often happen between fields that seem completely unrelated.

At some point, something will click stronger than the others. That’s when it makes sense to go deeper — from a Nerdish article to a book, a course, or a community of people who share that interest.

But don’t feel pressured to specialize before you’re ready. Curiosity is not a straight line. It’s perfectly fine to wander for a while before you find your direction.

The Nerdish library currently has hundreds of topics spanning science, history, health, art, technology, and daily life — and we add new ones regularly. If you decided to read everything in one go, it would take you around 50–60 hours. That’s more than two full days of genuinely interesting content.

Inside the app, you’ll find even more than what’s shown on this page, including topics we haven’t published on the web yet.

But honestly, the number matters less than the variety. Whether you have five minutes or an hour, there’s always something new to discover — and something that will make you think a little differently about the world around you.
