This week in Recommended Links: the mystery walker, cylindrical sails, the dumbing down of society, a child prodigy, and the hinge moment of humanity, among many other things. If you miss it, you're a fool.
This Week's Picks
The mystery walker that even the Internet couldn't decipher: His route passed through the Appalachian Trail, one of the great on-foot routes in the United States. He was discreet but not aloof. Jennifer Vickers, a black woman of about 70, shared more than 100 kilometers of the journey with him. It was she who heard him use the alias Ben Bilemy when registering at a hostel. “He ate M&M chocolates, was obsessed with distances between points and wanted to see a bear,” said Vickers.
This is how cylindrical sail ships work – The Magnus effect: Let's take a ball as an example. As the rotating ball travels through the air, its surface drags the gas it comes into contact with in the direction of its rotation and deflects it in a specific direction. By 'pushing' the air in the direction of its rotation, the ball experiences a force in the opposite direction. Therefore, that same object that would follow a straight path if it weren't rotating ends up experiencing a displacement in the same direction as its rotation.
The 17th-century lock that counts how many times it's used: The mechanism detected the number of times it had been opened, in a way that was both ingenious and artistic, using a knight holding a pointer against the dial. Every time the key is turned in the lock, the engraved dials rotate and the pointer indicates a number. The keyhole is hidden by the front leg of the man, which works on a pivot. When a button is pressed, the leg swings forward to reveal the keyhole. The door latch is released by tilting the man's hat.
These are the 10 most common spelling errors, according to the RAE: The Royal Spanish Academy (RAE) has on its official website a section of “frequently asked questions”, where it collects answers to the most frequently asked questions by users of the linguistic consultation service. Thus, although grammatical, lexical, and orthographic queries are made, the most common errors made when using Spanish are deduced in this section. In this way, we highlight 10 frequent errors according to the RAE.
The dumbing down of society as a strategy of domination: A few decades ago we believed that the ignorance of the population was due to a lack of information. Under the motto “information is power”, we considered that the more informed one was, the greater the chances of self-emancipation. But today we see how wrong we were. It turns out that the fact of constantly informing ourselves is what hinders thought. This happens because the information that reaches us is ephemeral and is quickly replaced by other information, which makes us immediately forget important news and stop investigating the heart of the matter.
They give a 12-year-old child prodigy four random notes on the piano. In 40 seconds she works magic: Less than a minute, 40 seconds, is what a 12-year-old piano prodigy takes to create an incredible score with four random notes. That is the time Alma Deutscher needed to demonstrate her skills on the program 60 Minutes.
Why some experts believe we are at a 'hinge moment' in human history: What is the best way to describe our current stage? Maybe you're tempted to describe it as “unprecedented” or “extraordinary”. But here's another adjective you may not have heard: “hinge”. It might not be the most elegant term, but it describes a potentially profound idea: we may be living through the most influential period of all time. The arguments go beyond the coronavirus pandemic and the politics of 2020.
From PS1 to PS5, through Sega Dreamcast and Nintendo Wii: these have been the development versions of some famous consoles: The purpose of this console is for developers to test their games on the console and thus polish everything necessary before they are released to the public. It also serves to test its power, learn about its functions, and experiment with novelties that could bring something new to the gaming experience. This is almost always specified by the manufacturer so that the developer can take advantage and make the most of all these novelties.
The pack of heroin, cocaine, and a syringe that Harrod's sold for soldiers in WWI: During World War I, several large department stores in London, including Harrod's, sold a drug kit to make combat more bearable for “our friends at the front”. The “useful gift” contained heroin, cocaine, and a syringe, ingredients and tools with which young soldiers could relieve the horror of the so-called “Great War.” Soldiers' girlfriends often went to the train station to say goodbye to their partners and gave them a few grams of cocaine to liven up their stay in the trenches.
Animals understand death more than previously thought: Some of the theoretical requirements that have been proposed as necessary to understand death are extremely high. Excessive. For example, the need for a theory of mind (the capacity to create mental models representing the minds of other individuals) or a concept of absence. But death in nature is much simpler and much more common than it is for us. In our urban world, we run the risk of forgetting that the dead are essentially broken bodies beyond repair.
The war of children against squirrels: When the Spanish arrived in California, they found vast prairies where California ground squirrels (Otospermophilus beecheyi) abounded, a type of ground squirrel that can reach 1.13 kg in weight before hibernating. Initially they were no problem, since they did not affect livestock, but they began to be when they attacked small orchards and gardens, having to resort to strychnine baits to contain them.
The 12-year-old slave who exposed the botanists: Edmond had manually pollinated it. He had carefully studied the plant and found the part of the flower that produced the pollen and also the stigma, the part of the plant that needed to be dusted with the pollen. He used a blade of grass to 'open' the small lid that separated them and fertilized the plant. Edmond had solved the mystery of vanilla pollination.
