As soon as the first typewriters, so the sign "@" will be displayed immediately on the keypad, where it remains to this day. However, it is not only used when writing a post or as a preposition, it can also refer to the expression "on the course" or "scale".

And his appearance in the email is likely to happen by chance, at least, so say scientists.
