ok, lets see how clever you are

So if you stand on your head, does gravity work differently?

My boobs say yes.

[stek]

Because your eyes are next to each other not one on top of the other.

You've not met MF then!

My boobs say yes.

A pity that Newton did not use your boobs instead of an apple.

If the handrail is longer but has to make one full revolution in constant time, it would have to travel faster to achieve this.

No it wouldn't. As long as the speed matches on the straight bits it doesn't matter how much longer it is.

[Doggy Styles]

Because the mirror reflects without reversing. Stuff at the bottom stays at the bottom, stuff at the left stays on the left etc.

This.

Good point. So it doesn't have to do a full revolution, it just has to keep up along the straight.

he would probably have never bothered to write it down, he would just keep studying the effect.

We could be waiting for some italian called graffiti to discover the new force called Graffitiy.

I've got an upside down fb profile pic from Oz in 2010 if you fancy a laugh...

surely the straight bit and the bend bits at the end are part of the same piece of hand rail so the whole thing moves at the same speed?

yes, but the hand rail doesn't do one revolution when the stairs do
