Technology
How the digital world actually works, from Wi-Fi to search engines.
How 5G Works
5G is the fifth generation of cellular technology, promising speeds up to 20 gigabits per second and latency as low as 1 millisecond. Here is how it achieves what 4G could not.
How AI Agents Work
AI agents can plan, use tools, and act on their own. Unlike chatbots that just answer questions, agents set goals, break tasks into steps, and keep working until the job is done. Here's the architecture behind autonomous AI.
How AI Hallucinations Happen
When AI makes things up, it feels confident doing it. That's the problem. Here's why large language models generate false information and how to think about the risk.
How Batteries Work
The battery in your phone is a controlled chemical reaction you can recharge. Here is what happens inside when you plug in, and why lithium-ion changed the world.
How Computer Memory (RAM) Works
RAM is your computer's short-term memory, holding data the CPU needs for active tasks. Here is what happens inside those memory chips when you open an app or load a file.
How Facial Recognition Works
Facial recognition turns the unique patterns of your face into data that computers can search, compare, and identify. Here's the surprising way it actually works.
How Fraud Detection Works
Banks catch fraud in milliseconds using machine learning to spot patterns humans miss. The same technology protects your purchases every day, but how does it actually work?
How Map Routing Works
Every time you ask for directions, a complex dance of algorithms, traffic data, and graph theory springs into action. Here's what actually happens when your phone calculates a route.
How PageRank Works
PageRank is the algorithm that made Google Google. It changed how we find information online by ranking web pages based on their connections rather than their content.
How Quantum Computing Works
Quantum computers don't just run faster. They exploit the physics of the subatomic world to solve problems that would take classical computers longer than the age of the universe.
How RLHF Works
RLHF is the technique that turned raw language models into helpful AI assistants. It uses human feedback to teach models what to say, not just how to say it.
How TikTok's Algorithm Works
TikTok's algorithm watches what you do and immediately adjusts what you see. It learns your preferences faster than any other social platform, and the way it works explains why the app is so addictive.
