is this bus going to the left or to the right?
-
errr neither?? :DntKnw:

errr neither?? :DntKnw:
there's a answer,it was asked to some
pre[schoolers and 95% got the answer
right.
-
Neither. It's just sitting there. :crazy:

Looks like a UFO to me...

it was a drawing of a bus shown to pre-schoolers.
I couldn't get the answer but it's so simple once
you know
-
Assuming it's a bus, then it's going right because the left windows are more stretched than the right ones.

no Ali,it's not a accurate down to scale pic,the clue is what
you don't see
-
ARRRRGGGHHHHH! This is like one of my competitions! :crazy:
-
to make you feel better 95% of all
pre-schoolers shown this drawing got
it right
-
That makes us feel a whole lot better Dare. :confused:
-
hint
-
The bus is going left because it only has a door on one side?

:D :D :good: :good: :good: :D

Fair enough.

Damn I is intelligent.
Just out of curiosity how were those of us on this side of the pond supposed to get the answer to that question without help?

youcould have said the bus was gpoing to the right
-
Jeez, think I'd better go back to pre-school. :-[

then we would have to change the question to which
way is the wagon heading

You has all going Dare >:D

The door is on the left of the bus on this side of the pond as well, since it's on the same side as the pavement. You wouldn't want the children to pour out into the middle of the road...
That said, the bus could have been reversing - in fact due to parallax (the window-stretching I referred to in my original answer), it should be going right. Since the door remains on the other side of the bus, it would therefore not be going forwards.

Sorry for confusing you, dare.
Parallax is one of the ways we use to spot the distances between ourselves and objects. If you move, any object you observe will change shape slightly. This is particularly noticeable if one of your eyes is shut (part of the reason humans have two eyes is because one image cancels out the other, aiding accurate measurement of moving objects). One form of parallax is how the object appears to change compared to the background when the observer moves.
Anyway, things elongate as they move (at least to the eye). The longer something is, the faster it is going. Unequal stretching means that it is travelling in a specific direction. The window on the left is longer than the one on the right and the neither the middle window or any other detail of the bus contradicts the movement. It is therefore moving right.
However, there remains the question of the door. All school buses I've ever heard of are designed to put schoolchildren onto the pavement rather than the middle of the road. For both the US and the UK, this means the door is on the left of the bus. If you could see the door and it was moving forwards, it would have to move left. This is dare's reasoning for his answer.
So how do you reconcile parallax and basic bus design? By remembering that buses generally possess both forward and reverse gears. Nobody said the bus had to be moving forwards (though the average pre-schooler has probably never seen a school bus reverse). So it could be reversing, in which case the window-stretching and the door position both fit.

I thought school buses were purely an American thing. Here normal buses are used and although they have passenger doors only on the pavement side they also have driver doors on the offside.
One thing I am curious about. Is the USA full of thousands of buses that drive kids to school then sit about all day doing nothing. Ten drive kids home in the afternoon and sit about doing nothing until the next morning. The concept of buses purely for school times should be completely uneconomical.
-
That's right, Steven. And then they sit around all summer doing nothing. They are used for other school functions, like sporting events and field trips.
In most small towns, like here in Lancaster, they are the only busses in town. The public bus line stopped operations in 1968.
-
The special school in town has its own school buses that only have one door. The mainstream ones only use standard buses, except for the sixth form, which I think ended up with at least one American-style bus among the ones the contracted company sent to it.

That's ok that they get summers off when they are new, they go on and live a long life ferrying passengers through central America for 50-60 years after they are retired from North America. Many are even still orange. Scary what they hold those things together with.
