Random Fact!

If it was the one at Covent Garden:
From top to bottom it is clockwise yes.
From bottom to top it is not. Therefore it spirals upwards anti-clockwise not clockwise

Clockwise. Upwards to the right, as stated in post 1.
 
Up untill 1818 all shoes were identical, there were no left and right. It didn't become widespread practice till 1850 tho. Most boots worn by soldiers in the American Civil war however were still identical left and right.

Oh and in Ancient Rome, if you were born with a crooked nose then it was considered a sign of leadership.

Two things:

- there's no such thing as a probability of zero
- if it were possible for something to have a probability of zero, the probability would still become 1 infinitely far down the timeline.

Of course there is? Take a random variable X with a probaility density function supported between a and b , the P(X>b+1) =0.

And no matter how infinite time is if the P(X>b+1) = 0 . X will never be greater than b+1.

EDIT: Simple example

John is born on the 01,01,1970 and Bob is bornon the 01,01,1971, Bob and John have infinite life spans. What's the probability that John is older than Bob?

Indeed you are correct :)

It was actually Russell Square station I was thinking of... That is anticlockwise and has 175 steps. Covent Garden has 195

Russell was French and is therefore unqualified to build spiral staircases correctly!

Or something

Edit: Russell Square Tube Station

Wrong because P(X>b+1) cannot be 0, as there is no such thing as something with a probability of zero. Nice unnecessary stats. equations and all but can you actually give me an example of something with a probability of zero?

0.00000000000000001% because there is a chance that our perception of time is incorrect, and Bob was actually born before John.

The probability of throwing a dice and getting a 7?

You haven't really thought this through, have you?

Thing is, we're bordering on existentialism and meta-physics now.

There IS a chance you could roll a six-sided die and it land on 7. The chance is unbelievably zero, but it isn't zero is it. It's like saying the chance of tomorrow being Friday is 1.... it isn't EXACTLY 1. To do with accuracy vs. sillyness.
