About Better Explained

My mission is to help you truly understand new concepts. Let’s move past dry facts and share the Aha! moments that make learning fun and memorable.

The guiding philosophy is this Einstein quote: “If you can’t explain it simply, you don’t understand it well enough.”

If an intuition-first approach resonates with you, you’ll feel right at home. There’s no pretenses, no fuddy teacher, just an excited friend sharing what actually made an idea click.

About Kalid Azad

Kalid Azad I’m an extremely curious person and love sharing insights with others. While studying Computer Science at Princeton University I started a site to explain concepts as I would have liked to learn them. Better Explained is a continuation of that idea.

After college I spent a few years at Microsoft as a program manager, built InstaCalc (a real-time, shareable calculator), started a Y Combinator startup, did software development for MindTouch, and now focus on my own projects. Feel free to reach me via my contact form. I’ve given a few interviews:

In terms of mathematical maturity, I’ve done well in school (graduated with honors, 99th percentile in GMAT/GRE/SAT) but am not a professional mathematician. I’m an impassioned amateur figuring out my path to lifelong learning, always looking to improve my understanding, and happy to have you along.

Thoughts On Learning

  • Ideas start hard and finish simple. Complicated ideas get easier. Why? Well, the idea is the same, our thinking process has improved. Multiplication flummoxed the Romans until a number system came along. I know that math, science, business, or any topic can become intuitive after overcoming the initial complexity.

  • The best teacher is you – after you’ve learned the subject. You, 10 minutes after learning a new idea, are the perfect tutor for your current self. You overcame the difficulties and can explain the solution in language that makes sense. We can’t go back in time, but we can capture Aha! moments as soon as they happen. Some lucky soul can avoid the pothole we just climbed out of.

  • Get a map, not directions. Memorization isn’t understanding: you follow the recipe, apply the formula, and get from A to B without knowing why. Directions “work”, but what about wrong turns? A new destination? Helping a friend who’s lost at point C, not A? This site is about sharing maps, the intuitions that get you from any point to any other point. We’ll leave the raw details for the encyclopedias.

  • I still don’t know (and that’s OK with me). Learning is a constant process of updating what you thought you knew. Gaps aren’t “holes” to be ashamed of, they are leaks in your roof that you can patch up. I love finding mistakes in my thinking: it’s one less misconception.

I’m still far from a real understanding of most ideas, and that’s where you come in. I’m always scrounging for more insights, so send ’em along :).
