Re: Interesting little facts...
The longest border that France has with another country is in South America!
(Only know this cos a group of us at a quiz sat and worked out all the borders that France (Europe) has with other countries!! Gobsmacked to find it wasn't even on this continent!!)

No one at the pub quiz knew it either - not even the French! He won't be able to use that question again though as we all know now!!Taipan wrote: ↑Wed Jul 12, 2023 11:15 am
I never knew that! Everydays a school day!

It also can wreck vehicle paintwork. I've had my own battles with the sneaky snotters.

Re: Interesting little facts...
OK, this tread is dying. My turn.
The speed of light is not what you think. We can only measure a two way average and therefore, it could be instantaneous in one direction and half the rated speed in the other (anisotropic). This has the interesting property of suggesting what we see all those zillions of "light years" away is the instantaneous actual state of the universe and to have any causal effect, we'd have to travel at half the commonly assumed (isotropic) value of c to get there. Naturally we wouldn't even notice the difference!
It's a head bender but there is no conceivable experiment to "prove" the one way speed of light.
I look forwards to anyone who disagrees with some enthusiasm. I love having arguments when I know I'm right!

France also has the longest internal domestic flight doesn't it? Paris to Reunion in the Indian Ocean, still in France.

Re: Interesting little facts...
I thought it would be much further, but the horizon at sea is only 3 miles.

Re: Interesting little facts...
the horizon at sea level is three miles away....which is why ships have tall bits to steer from......
I did mention elsewhere that I am a pedantic bastard (though my parents were married).

Re: Interesting little facts...
At sea level the horizon is 0 miles away, being as your eyes would be level with the sea.

Re: Interesting little facts...
All eyes at sea level are equal height.
That's at actual sea level rather than the theoretical sea level, chart datum plus what the tide tables tell you and adjusted for local weather conditions. Atmospheric pressure, geographical features, and wind strength and direction can have a large effect on a local level.

So most of the time with your eyes at "sea level" you'd be under water

Re: Interesting little facts...
The tide doesn't actually come in and go out, or rise and fall, however you want to phrase it.

Re: Interesting little facts...
Which is also why the moon always shows the same side to the Earth.
One day the earth will also always show the same side to the Moon, at which time the moon will stop rising and setting - it'll just be 'fixed' in the sky and the only way to make it rise or fall will be to move. I suppose it could be the case it'll be fixed over the Pacific Ocean, in which case most people would never see it.
Bit far off for now though, probably shouldn't worry about it.
