The line came after the flags

You wake on Friday, 15 August 1947. The flag has changed. The Viceroy is now a Governor-General. Your village still sits where it sat yesterday. What you do not have, and will not have until Sunday, is the line that says which country the v

In 2020, China and Nepal jointly announced a new official height for the mountain the world calls Everest: 8,848.86 metres. It was the end of a long diplomatic disagreement, but buried in the announcement was something stranger than the num
