“There is nothing more deceptive than an obvious fact”*…
Your correspondent is heading into his annual Holiday hiatus (regular service will resume on January 2), so by way of being sure that readers have something to occupy them in the meantime…
We’ve spent time before with Hans Rosling (“By the Numbers…” and “Poverty is an anomaly to rich people. It is very difficult to make out why people who want dinner do not ring the bell“*…), the man who reasons that experts cannot solve major challenges if they do not operate on facts. “But first you need to erase preconceived ideas,” he says, “and that is the difficult thing.” Nature has done us all the service of collecting a wide variety of his amazing, mind-changing presentations…
Hans Rosling knew never to flee from men wielding machetes. “The risk is higher if you run than if you face them,” he says. So, in 1989, when an angry mob confronted him at the field laboratory he had set up in what is now the Democratic Republic of the Congo, Rosling tried to appear calm. “I thought, ‘I need to use the resources I have, and I am good at talking’.”
Rosling, a physician and epidemiologist, pulled from his knapsack a handful of photographs of people from different parts of Africa who had been crippled by konzo, an incurable disease that was affecting many in this community, too. Through an interpreter, he explained that he believed he knew the cause, and he wanted to test local people’s blood to be sure. A few minutes into his demonstration, an old woman stepped forward and addressed the crowd in support of the research. After the more aggressive members of the mob stopped waving their machetes, she rolled up her sleeve. Most followed her lead. “You can do anything as long as you talk with people and listen to people and talk with the intelligentsia of the community,” says Rosling.
He is still trying to arm influential people with facts. He has become a trusted counsellor and speaker of plain truth to United Nations leaders, billionaire executives such as Facebook’s Mark Zuckerberg and politicians including Al Gore. Even Fidel Castro called on the slim, bespectacled Swede for advice. Rosling’s video lectures on global health and economics have elevated him to viral celebrity status, and he has been listed among the 100 most influential people in the world by the magazines Time and Foreign Policy. Melinda Gates of the Bill & Melinda Gates Foundation says, “To have Hans Rosling as a teacher is one of the biggest honors in the world.”…

As we celebrate facts, we might send amazing birthday greetings to John Nevil Maskelyne; he was born on this date in 1839. An accomplished stage magician, he was also an inventor, perhaps most notably, of the first pay toilet (the “penny toilet,” origin of the phrase “spend a penny”).
His son, Nevil Maskelyne, was also a magician and inventor– and the perpetrator of the first instance of electronic hacking.
