Packages  trivial question
Posted:

I'm sorry for such a trivial question, but what does mean the backapostroph behind the package name, when one wants to get package?
For example: << PhysicalConstants`
I'm trying to find it in the documentation, but I'm not successfull. Is it the same symbol as it is used for NumberMarks i.e. 0.3333333333333333` for example?
I think, that in the case of packages it means something like "definition space", because for example: Remove["Global`*"] should remove all the symbol definitions in current session.
But I'm still confused of the little but magic `
Thanks in advance for any enlightenment
Jakub
