Preface

You can think of Physics Capsule as an online book and even use it like one. What this means is that you will gain most from Physics Capsule if you use it dynamically based on your existing knowledge of physics. Here are a few scenarios:

  1. If you have a background in physics or mathematics at, say, the undergraduate level, you will be familiar with a lot of the basics. Take the probabilistic approach: roll the dice and we will offer you a completely random article to read. Start with that if you like it, else roll the dice again.

  2. Regardless of your background if you have a favourite field take the deterministic approach and just start with that field. Do you like electromagnetism more than optics? Just open the contents page and start reading about electromagnetism in order.

  3. Know nothing and have no idea what you like? That is perfectly normal. You can take either approach: roll the dice and get started, going from article to article trying to understand keywords adventurously; or, if that tires you out, start at square one with the first article on classical mechanics or from Appendix A (mathematical methods) and go in the most faithfully bookish order possible.

Regardless of which approach you take remember that physics is fun and interesting to learn and it becomes a lot more fun if you can invest some time and effort into understanding the mathematical language physicists speak in.

Looking for articles on a topic not already addressed here? You can always of your choice.

‘Poets say science takes away from the beauty of the stars – mere globs of gas atoms. I, too, can see the stars on a desert night, and feel them. But do I see less or more?’
