How did you do this? Did you do a voronoi tesselation with all the capitals and then calculated the area of each zone?

I didn't use an accurate method but I assume it was good enough. I used a set of about 16.000 coordinates and for each one calculated the closest capital. For each integer latitude the first point would be 0 longitude, the next one would be longitude 223 km east until 360° was reached. Hope that makes sense... so for example that means 180 points on the Equator, 100 at 40°N or S... I couldn't think of a way of making a perfect calculation.

This has now been recomputed with about 4 million points spaced an equal distance apart on the Earth's surface.

Should the country borders still be visible when you zoom in?

Level ∞
May 17, 2024
No, but I didn't bother fixing it. At some point the zoomed-in border-opacity got set to !important in the style-sheet. Which makes it really tough to override. We should probably avoid !important in general in the stylesheet. But this is an edge case on a single quiz so I'm not going to worry about it.

Could you make it more clear what we're supposed to do? I thought a random point on earth would be chosen, and we would have to guess the capitals closest to it. It took until I guessed Ottawa by pure chance that I understood what I was supposed to do.

Basically you have to guess the capitals that are far away from any other capital because they cover the largest area of potential random points that would be closer to them than any other capital.

The map is a hint because it shows the area "covered" by every capital and you go for the biggest ones.

Also technically it's not so important that the capital is far away from other capitals but that it's the northern/southern/easter/westermost of the bunch before you get a lot of empty space in at least one direction.

This is a nonesensical quiz but my good knowledge of remote capitals helped me go through. For example why none of the European cities is an answer? If I land for example randomly in any part of Europe I stand a good chance of being close to 40+ national capitals...
+22
Level 80
May 17, 2024
Because for any capital in Europe any point is very likely to be closer to a different capital. For e.g. Wellington, there's lots of space around it not close to any other capitals, so lots of points in the pacific are closest to Wellington. It's which capitals have the most points around them that are closest to that capital

Or differently phrased, all the lines on this map are where another capital takes over from being closer (sorry for my bad English). So each capital gets their own section. Some sections are bigger than others, so if you let's crash on earth on a random point, the chances to crash in a bigger section are bigger.

Basicly look at the map and try to figure out which capital lies in the biggest sections.

But that's the point -- when you are close to a lot of capitals simultaneously, they all have a pretty low chance of being the absolute closest to you.

Each capital city on the map simply has an area drawn around it to represent where you would have to land in order for that capital to be the closest. Obviously the more remote capitals have larger areas, so you have a greater chance of landing in those areas if you were dropped onto the globe randomly.

I think I could have had a better stab at the required capitals, if it was more obvious which shapes were the 20 largest, washington space, Lisbon space, Helsinki space, all look like contenders.
