Motoring Madness
Here's an amusing little game you can play the next time you're in your car. It's natural to think of the car moving and the earth being stationary, but if you try hard, you can reverse this situation, in your mind at least. Think of your car as being absolutely fixed in space, and think of the earth as being an enormous ball, rotating beneath the car's wheels. It takes a little concentration, but if you persevere, you will find you can maintain the illusion for up to a couple of minutes at a time. The next stage is to imagine that the controls you are using - steering wheel, brake, accelerator - are no longer the controls of your car, but are instead the controls of the earth. Step on the gas a little, and you will be able to feel the earth spinning just that little bit faster on its axis. Now turn the steering wheel a few degrees, and (incredible though it seems) you will actually feel the earth - that enormous sphere of molten magma - tilting on its axis, bringing a fresh piece of road beneath your wheels. Getting the hang of it now? Weird feeling, isn't it ....
HEY! WATCH OUT FOR THAT LORRY.....!!
