Physics Capsule is built around a *Learn* section that sets it apart from other physics magazines and learning sites. From the beginning, it has been our aim to combine teaching and learning physics into one bundle in a simple, easy to understand, yet not a trivialising manner.

Our *Learn* collection is growing and new articles are added to it every week. If you want some articles more speedily than others, please let us know. You can use the contents section below to pick and go straight to any article or topic and start learning. Have fun.
