Can you tell me what is the difference between direction and dimension?
For a more specific answer, you need to clarify the context.
I want it scientifically .....not from dictionary
we still need a context.
Several of the listed definitions of "dimension" are scientific or mathematical ones, applied in different contexts.
Ok thank you very much
The difference is that, in general, although direction may be considered a dimension, there are many other dimensions besides direction, such as distance and time. Furthermore, direction and distance can be combined to form another dimension, modeled mathematically as a vector.
Reading this again, I feel inclined to say that they are just not comparable. When you come across two words that you need to distinguish between, the best thing to do is to read passages in which each word is used and get a flavour of their meanings.
I would have a similar problem if you had asked what the difference is between a giraffe and singing. There is really no occasion that I could think of where they could be used interchangeably - so no confusion could arise.
Separate names with a comma.
