It is important to master aperture because once you master aperture, you get real creative control over your camera.

Each time you move from the f stop of one number to the next smaller number, it doubles the lense size and vice versa 

When you move from one shutter speed setting to the next smaller shutter speed setting then it will half the amount of light that the camera lets in

Aperture is related to depth of field because large aperture will decrease depth of field and small aperture will increase depth of field.

According to the author, the best way to get your head around aperture is to get out your camera and do some experimenting.

The size aperture that is typically used in landscape photography is a smaller appeture. The appeture size that is typically used in portrait photography is a larger apeture. For a macro picture you want a shallow depth of feel so you would need a larger aperture. You want a smaller sized aperture for landscape photography because you want to focus on the whole landscape whereas if you where taking portrait photography, then you want to focus on the person instead of everything in the background which would be distracting. You would want a larger aperture because you want to focus in on the main subject that is taking up the picture.
