2 June 2016 The world’s longest cross-sea bridge HK-Zhuhai-Macao Bridge was successfully linked up.
Starting from the Lantau Island in Hong Kong, the Y-shaped bridge has a total length of about 55 km, including a 6.7 km underwater tunnel and a 23-km bridge over the sea, making it the longest cross-sea bridge in the world.
The bridge will serve as an important channel linking Hong Kong, Macao, Zhuhai and the western part of the Pearl River Delta, one of the most economically-developed areas in the Chinese mainland.
The cost of the bridge was around 1.5bn USD.
Wonderful tale by Ben Orlin “Math with Bad Drawings”, of a creature exploring the world of numbers, very much in the spirit of “Flatland”.

In 1982 Douglas Hofstadter wrote about Number Numbness. We’re still befuddled in the face of millions and billions, let alone trillions or even bigger numbers.
That’s the reason for IsThatABigNumber.com: to help anyone develop their number sense by putting big numbers in context and providing meaningful comparisons.

Stand on Zanzibar is a 1968 science fiction novel by John Brunner. It takes its name from the author’s projection that by 2010, if all the world’s population stood shoulder to shoulder, the island of Zanzibar could accommodate them.
