For many of us, the mere words “Pythagoras’s theorem” are enough to revive pencil-smudged exercise books and desperate attempts to copy classmates’ work. And yet, it turns out the name that has struck dread in countless school kids over the centuries is about as accurate as this writer’s attempts at geometry. Because although it is assumed that the legendary Greek philosopher Pythagoras himself was to thank for the equation a2 + b2 = c2, it turns out it was being used some 1,000 years before his time. Archaeologists have found the equation on a Babylonian tablet which was used for teaching back in 1770 BCE – centuries before Pythagoras’s birth in around 570 BC, as IFL Science notes. Another earlier tablet, from between 1800 and 1600 BC, even features a square with labelled triangles inside. Translations of the markings, which followed the base 60 counting system used by ancient Babylonians, prove that these mathematicians were familiar with Pythagorean theorem (although, obviously, they didn’t call it that) as well as other advanced mathematical principles. In a paper dedicated to the discovery, data scientist Bruce Ratner wrote: "The conclusion is inescapable. The Babylonians knew the relation between the length of the diagonal of a square and its side: d=square root of 2. "This was probably the first number known to be irrational. However, this in turn means that they were familiar with the Pythagorean Theorem – or, at the very least, with its special case for the diagonal of a square [...] more than a thousand years before the great sage for whom it was named." And yet, one key problem remains unsolved: why did the equation become equated with the famous Greek? Well, most likely because Pythagoras wanted it to be. In his paper, Ratner points out that although the Ionian icon is widely considered the first bonafide mathematician, little is known about his specific mathematical achievements. Unlike his successors, he didn’t write any books that we know of, so there’s no written evidence of his work. However, we do have proof that he founded a semi-religious school called the Semicircle of Pythagoras, which followed a strict code of secrecy. As Ratner explained: “Pythagorean knowledge was passed on from one generation to the next by word of mouth, as writing material was scarce. Moreover, out of respect for their leader, many of the discoveries made by the Pythagoreans were attributed to Pythagoras himself. “Consequently, of Pythagoras’ actual work nothing is known. On the other hand, his school practiced collectivism, making it hard to distinguish between the work of Pythagoras and that of his followers. “Therefore, the true discovery of a particular Pythagorean result may never be known.” Still, he stressed, even though Pythagoras wasn’t the brains behind the most famous formula in maths, he does deserve a little credit for putting it on the map.

Meta has added new edit features and voice notes to Instagram Threads, as it continues to try and take over from Twitter. “Rolling out Edit and Voice Threads today. Enjoy!” wrote Meta chief executive Mark Zuckerberg on the site. They are yet more changes as Meta looks to keep the momentum from the launch of Threads, during which it became the fastest growing app in the world but has struggled to keep users reading and posting. As with when Threads first launched, the new features come amid loud questions over the future of X since Elon Musk took over and changed its name from Twitter. Twitter had previously taken years to add an edit button, and put it behind its Twitter Blue paid-for subscription tier. Some of its delay was thought to be a result of concerns about how to add the feature without contributing to disinformation. Some had expressed concern that the button could be used to edit popular posts to change their wording, or suggest that information had been available at different times, for instance. Twitter addressed that problem by adding a clear marker when a post had been edited, and allowing users to see the history of those edits. Threads does not offer an edit history, and is not thought to be adding one. But it did add a tiny icon making clear that the post has been revised. Threads has also added what it called “Voice Threads”, which function as small audio posts. Users can press a record button and that will then make a playable audio file, which will also include captions. The two new features are the latest changes from Meta to Instagram Threads, which was launched in an early version and has been updated rapidly ever since. Those have included a chronological feed and the ability to use the site on the web.
