Choose vs Select

[Vishnya]

Hello,
I often use sentences with choose (select). Can you explain the difference between them? Which is better to use in technical documentation?
TIA, Jane.

In common usage, both 'choose' and 'select' are often interchanged. Yet in some contexts, this isn't possible. For example, when 'choose' has the sense of 'decide': In the end they chose not to go to the beach.

Some say that one implies more thought than the other -- there seems to be a bit of disagreement on this. Also, 'choose' is more commonly used than 'select', which, in some contexts, might be slightly formal.
