What is Poutine?

 

I told a Canadian workmate I'd seen a Canadian restaurant at the top of Leith walk, she visited the same night, and insisted on the next mornings zoom everyone went to and tried it.

 

I told my Kansian wife, and she demands we book a table and go.  Is Down the hatch, name of the place.

 

Both insist it has to be the right 'squeaky cheese'.

 

But when i look it it up it just looks like chips and gravy, and i can get that from Javits or nine dragons.

 

@Maple Leaf, OR @Sharpie, please educate me, and is this some Canadian national dish like the Aussies have meat floaters, which always sounded like a pie dumped in pe soup to me.

Love Down the Hatch.

If you stuck one end of a hose in the sea and put the other end in space would it sook all the water out?

If you are thinking the vaccum of outer space  would suck the water up the hose, I don't think it would. A vaccum doesn't suck, which is why our atmosphere doesn't need a container to keep it attached to the planet. If it was capilliary motion, I don't think that would resist gravity enough. Also, as the air pressure thins around the hose, our water would start to turn into a gas and boil off.

I think the idea that vaccums suck is either due to vaccum cleaners or the fact to create a vaccum chamber on earth, we suck all the air out using a compressor. 

I thought about this another way to see if it could still work if we created a gigantic syphon. Assuming our gigantic straw/hose wasn't too long that the air pressure needed to displace the water wasn't too low (unfortunately it equalises at about 10 metres), could we use gravity to get the water moving and then once the hose was  out of  the atmosphere, let the water boil off in the vaccum of space.?

But I don't think we would ever be able to create a situation where the syphon is lower than sea level (could maybe do this on some terrain on the planet surface, ie a lake sitting well above sea level) because gravity is always a force with a vector towards the centre of the earth. So as soon as you go even perpendicular through the atmosphere to reach outer space,  you are working against gravity. 

That said, if you could make a hose large enough to reach Jupiters gravity, maybe that would create a strong enough syphon? Very interesting thought experiment, I could be way off with these musings.

Just to add meat to the bones, vacuum cleaners work by expelling air and creating a vacuum.

 

As you say, this doesn't suck air in, what's actually happening is the weight of the atmosphere pushes air in to the newly created area of low pressure.

I was thinking more along the lines of seeing people getting sucked out of spaceships when airlocks open in films.

Easiest way to visualise this in practice is if you have one of the modern water bottles. That will have a drinking spout and also you should see a separate small valve/opening on the lid.

Cover that valve and try and suck out the liquid and you won't be able to, the air has to get in and displace the liquid you are removing.

If you've seen backdraft it's the same thing, when a fire burns it eats oxygen in the air, making the air inside less dense and therefore lower pressure.

When an outside door's opened, air rushes into the area of low pressure, feeding the fire and Whoosh!

Don't quote me because I'm only surmising, but I think it has something to do with the batter's hitting ability on pitches in the strike zone.  The red areas indicate that he hits pitches well in those areas, blue that he hits poorly in those areas.  Grey is maybe average?

 

The whole thing is TMI for me.

Yes, it's all very scientific...or at least data-crunchingly heavy.

 

I was reading something last night about the throwing ability of a human and will put it on here but don't want to try and quote it or I'll mis-remember something.

 

Your explanation makes sense though: red = batter's hot zone, blue = cold?

Or red = danger (for the pitcher).

No. Not sure what would lead you to think that - we can literally launch rockets and satellites into space. 

You're not a flattard, btw, as that sounds suspiciously like the dome argument or the denial of gravity for some daft "buoyancy" theory and insist that the vaccum of space would suck away our atmosphere. 

Which is preposterously wrong since here we are, breathing away quite happily

No, definitely not a flat earther! Is the earth not a closed system though, as matter doesn't leave due to gravity? Would that not give it a similarity to a sealed container?

That's actually an interesting point, but we do lose some of our atmosphere (the thinnest part actually reaches the moon) to solar winds whipping it away. But not enough that we don't replace it from plankton, algae and plants/trees replacing what we lose. 

I think it's considered mostly closed, in that we get some stuff from outer space (meteors really) and lose those hydrogen atoms but mostly as you state, gravity makes us a pretty much closed system, which I misinterpreted when I thought you might be about to chuck the dome theory in! Apols for that. 

If you enjoy science stuff, my favouriter practical science guy on utube is The Action Lab as he actually tests theories and ideas.

If you want your mind blown (like mine was) on quantum mechanics etc, Arvin Ash is absolutely has the best explanations for laypersons on youtube. His explanation of particle/wave duality was the first time it has ever really made sense. 

Sci-man Dan  is amusing when he rips the flat earthers. Have you watched Beyond The Curve on Netflix? It's brilliant, producers just point cameras at a bunch of flat earthers and let them do the rest, with predictable results.

I did reply to this but not sure where it went?! Must have been sucked out of kickback through a hose or something... 

I'll have a look for Arvin Ash but as i don't have netflix i doubt I'll be able to watch Beypnd the Curve

When engineers prop up one of the temporary 'speed limit' signs by a road, does this legally alter the speed limit for the duration it is present? Could someone be penalised if they were caught exceeding that limit or does it have no legal standing?

Probably because if you move into the nearside lane you get boxed in and can't get out again and you end up watching Alfred and Joyce and their caravan slowly pass you again after you sailed passed them earlier 😄

No. For example, there are temporary speed limits on the A90 from Dundee to Aberdeen. There are also 'average speed cameras' too. If you went through those at 70mph, when the temporary speed was 50mph you would not get clocked. Would be absolute carnage if they tried to enforce it, so 'speed camera's' are kept the same all the time.
