OK bad wording.

no
I'm not sure about your 'standing in the corner' theory (I think its wrong) but I was agreeing with the 'you cant add random velocities'. Actaually not agreeing. More 'Idontknowing'
has anyone the answer to the original problem?

Originally posted by wolfgang59I think the reflection is the key here. If an object approaches a wall, the chances that it will then move along the wall are much smaller than that it will move away from the wall because only two angles out of 180 possible degrees are along the wall.
I think that a randomly moving object has as much chance of being in centre as at edge or corner.
Consider an infinite checker board plane. We would all agree that for a random moving object there is no more chance of it being near a corner or near the centre of a square.
But if we now consider that every time that object crosses over into another s ...[text shortened]... regardless of whether its a corner or not.
(Someone will surely word this better later on!!)
Originally posted by Coconutfreeway, because on the freeway you are going 60 mph picking up bugs like crazy. When your car is still, the beetles have an opportunity to LAND on it, but that is not considered hitting if it can remove itself from the surface of your car. If the bug can walk across your car and leave it of it's own will, or whatever a beetle has...
do more bugs hit your car when it's parked, or on the highway?
Originally posted by AThousandYoungAnd by increasing speed you increase the number of bugs that may potentially hit you at any given interval of time. Which makes the car analogy a poor one with respect to the original problem.
More bugs splatter on my windshield on the freeway, but I don't know how many just bump it when it's parked.
Originally posted by PalynkaGood point. You need an enclosed space to properly model the problem.

Originally posted by PalynkaAh, I see you did cover it.
Not necessarily, it all depends on the motion properties of both. I believe that if both follow an unrestricted random movement*, the chances would be the same. However, the walls may change this significantly. Once you hit a wall, your next direction is restricted and therefore your movement is not unrestrictedly random.
So I would guess that standing st ...[text shortened]... ** Edit 2 - Which wouldn't then be a brownian motion, obviously, for the pedants out there. 😉
