IN or AT or ON

We can think of at as one-dimensional, referring to a specific place or position in space. On is two dimensional, referring to the position of something in relation to a surface. In is by contrast three-dimensional, referring to the position of something in relation to the things that surround it. Thinking of the prepositions in these terms helps us explain certain facts. For instance, in is generally used for larger places and at for smaller, more specific places, so we say:

1. We arrived in Inverness two hours ago.
   But:
2. We arrived at the campsite two hours ago.

However, if we think of a city or larger place as a specific point in space, we can use at, e.g.:
The train stops at Birmingham and Bristol.
Or if we think of a smaller place as three dimensional, we can use in, e.g.:
We've lived in this little village for many years.

1. at - is used for fixed points in time (e.g.: clock times) and fixed positions.
2. on - is used to describe a position in a line, list or sequence. So it is used for days, dates (The calendar is a list) and surfaces or lines.
3. in - is used to describe something in relation to the things around it in time or space. in is used for periods of time and three dimensional spaces or containers.
