Right. In most of the first twenty results, the term "vector pi" simply means "some unknown or variable vector, which is named 'pi', as in the Greek letter."
In a few of them, they say something like "we rotate the vector pi radians". This is just a use of radian measure. (pi radians = 3.14 ... radians = 180 degrees).
There are mathematical objects called "vectors," that, roughly speaking, are used to indicate a point in space, or a direction and speed of travel.
Like any mathematical objects, there are times when we want to talk about them, when we don't know what they are. So we give them names. Sometimes we name them with letters like "A" or "x", and sometimes we name them with greek letters, like "pi" or "gamma". The google search just gives some instances of people having a particular vector whose name is pi. (Either that, or they're taking a vector and rotating it some multiple of pi radians.)
So really, it doesn't mean anything, just like the terms "number x" and "function f" don't mean anything in particular.
Good evening. Here is the News for parrots. No parrots were involved in an accident on the M1 today, when a lorry carrying high octane fuel was in collision with a bollard ... that is a bollard and not a parrot. A spokesman for parrots said he was glad no parrots were involved. The Minister of Technology today met the three Russian leaders to discuss a £4 million airliner deal. None of them went in the cage, or swung on the little wooden trapeze, or ate any of the nice millet seed, yum, yum.
