Channel 5 are on the phone …they want to talk to you about your pitch for a new reality TV show ..
Channel 4 have already got "Come Dine With Me".

sounds like BSl
Edinburgh is further north than both toronto and Moscow ( russia) but they get freezing cold winters. that just seems wrong
If sir would permit me to make an introduction?
TJ, the Gulfstream. The Gulfstream, TJ.
Yes! English, Welsh and BSL
That's why the Wales Govt COVID press conferences always had signing
Just posted this link on the space, astronauts and rocket thread, but it properly ought to be here. JWST has just revisited the tiny patch of sky that Hubble looked at for the Ultra-deep field view, which took twenty days to produce. JWST has picked up more objects that weren’t visible in the original image, in twenty hours…

IHN - I know why it happens but it still seems weird 🙂
Its just is it a number or just a placeholder.?
Define 'number'.
The set of natural numbers is what most people think of - the question of whether or not natural numbers includes zero seems controversial. For me it would seem to be a number. If I ask you how many fingers I am holding up, the answer to the question 'how many' must be a number, right? But you could legitimately answer 'zero'. I can never hold up -3 fingers, so the answer can never be -3, but it can be zero. You could say that the answer zero is a special case by saying 'you are not holding up any fingers therefore the question is invalid' and if we had no word for zero that would be correct. But we do.
Although, for you to answer zero you would expect me to be holding up two fists. But if I didn't hold my hands up at all, would you still say zero or would you say that the question is unanswerable and the answer is therefore not defined?
It's a bit like a problem we face in IT. If you fill in a form with say your address on it, you can leave one line blank for example the second line after your street and house number. Does that mean that you just didn't fill that in, or is it that you don't have a second line? We have to distinguish between the two when we store your address. There's a difference between no data and an intentionally blank line or, in maths terms, 'zero' and 'undefined'. So in the case of fingers, there's a difference between me holding up two fists and you having your eyes shut. In both cases you see no fingers, but you intuitively know there's a difference.

That's the explanation I always used too, but someone told me the other day that the relatively shallow sea around us has more of an impact than the gulfstream.
the mississippi flows uphill in places due to centrifugal force
Are you sure? Momentum perhaps. I'm not certain that's the right word either, fluid dynamics is weird. Pressure? Water flows upwards out of fountains.
I can ride a bike uphill without pedalling, given sufficient downhill just before it.
No I am not sure - it baffles me but centrifugal force means that there is a slight upward force as you get near to the equator so at one point this is greater than downward pull from gravity as the area is very flat. so for a stretch the river gets further fromthe centre of the earth. add in that the earth is not a sphere and it all gets confusing

apparently sea level is 20 km further from the centre of the earth at the equator compared to the poles because of the centrifugal force. My head just burst.

So Sirius will be in proximity of earth in about 500,000 years.
At which time the politics and brexit threads on STW will still be going strong with windbaggery coming from descendants of today’s protagonists

Ah, now that makes more sense to my GSCE Physics mind. The Earth isn't a globe, it's an "oblate spheroid" - it's flattened at the poles. So water might well seemingly flow 'uphill' due to centrifugal (or is it centripetal?) force, but that's the force acting on the Earth as a whole which has deformed it rather than force directly on the river itself. Sea levels are going to be higher at the equator because of spin, the same reason as you need a rear mudguard if you don't want to end a ride looking like a sepia Dickie Davies.
Maybe.
because of the centrifugal force
Also worth noting that centrifugal force is relativistic - it's only really a 'thing' if the observer is in a rotating frame of reference and needs a way to describe the apparent force pushing an object away from the centre of that rotation, for the external observer in a static frame of reference all that exists is the centripetal force that stops the object from continuing in a straight line.
so the river ends up flowing away from the centre of the earth. Weird.
