Two Tiananmen Mysteries: Tank Man and Xi’s Wife

Unless you live in China, you have almost certainly seen the iconic photo or video of the man with two shopping bags who faced down a column of tanks as they moved through Tiananmen Square. And you might remember the moment when several people pulled him out of harm's way. The photo, by AP photographer Jeff Widener, is one of the most iconic and stirring images in history – the mechanized killing power of the state stopped in its tracks by a single human being. To this day, that human being has never been identified. Theories abound about what happened to him. Was he killed? Did he go into hiding? Surely no one has ever been so widely recognized and yet so anonymous.


From the other side of the square, another interesting image: Chinese president Xi Jinping's wife Peng Liyuan is a famous folk singer. Several years ago, a photo surfaced online which seemed to show her singing to the troops on Tiananmen square around the time of the massacre. The image was quickly wiped from Chinese internet, but you can see a snapshot of it here. Xi himself has no misgivings about Tiananmen, in case you are wondering.

Coffee is one of the most popular drinks in the world, but that means it creates a lot of waste in the form of cups and used coffee grinds. Every year, we drink out of 600 billion single-use plastic and paper cups, most of which end up in a landfill or our environment. Could coffee also contribute to a more sustainable future? A German company is now recovering leftover coffee grounds from bars, restaurants and hotels, and it's recycling them into reusable coffee cups. In other words, they're creating cups of coffee made from coffee.

What technology was used to assist Eliud Kipchoge's historic sub two-hour marathon time?

A lot. If you watched the video of him, you saw that he was within a pace group, a whole bunch of runners in front of him cutting the wind. Some runners behind him, actually improving his wind resistance by having people behind him. There was a green laser showing him exactly what time he had to run. He had really high-tech gels that he took, these Maurten gels. I actually like those a lot, too. But the main thing were the shoes. These are the early prototypes of the shoes or the first version. He's now in the third version. But what's most important is there is a carbon fiber plate. You cannot bend this thing. So, Nike introduced these shoes, I don't know, two years ago. Now, there's a new generation. It's very controversial.

Will the Catalonia question be a big issue in the Spanish election coming up in November?

You bet it will. Passions have been further inflamed now, and the question that has been difficult from the very beginning, by the very heavy prison sentences that was given to those that are accused of sedition, that is organizing the independence referendum. So, passions are heating up. It will be a difficult issue for the entire Spanish political system to handle for years to come.

You'd think, being the relatively hopeful person that you are, that the nauseating anguish of Brexit would be more or less over now that UK Prime Minister Boris Johnson has finally reached a deal with Brussels on how to extricate the UK from the European Union.
