Here’s what the UK looks like when you display the 24,727 pubs in the country on a single map. You like beer and you want to visit them all? Know that you will have to travel 45,495 km to get a beer in each of them. This optimal path was calculated by researchers at the University of Waterloo using data from the Pubs Galore website. This calculation, which is much more complex than it appears, have required two years of work! Long live science.
