HK-Zhuhai-Macao Bridge Meets in the Middle

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.

Benford’s Brain-boggling Law

Take a set of numbers collected from “the wild”.  You might take company profits, city population statistics, street numbers or odometer readings.  How many of the numbers in your set start with “1″? how many with “2″? with “3″?, “4″? …

Amazing as it sounds, these leading digits are NOT evenly distributed but follow a pattern (30% “1″s, down to less than 5% “9″s). This pattern is so reliable, it’s been used in fraud detection, to trap companies cooking their books: the invented numbers did not follow Benford’s Law.

Follow the link for a fascinating explanation of why this is so.

Cosmic Eye: Powers of Ten

This video recreates the classic “Powers of Ten” film, zooming out to larger and larger scales to the limits of our understanding of the universe, and then zooming in again, down to the smallest things we know about.

It’s an excellent way of illustrating relative magnitudes of distance. One gripe: it all happens a bit too quickly: try watching it at half speed.
