Matthew McConaughey revealed how a dream led to his children's book 'Just Because' and why he never gets tired of his catchphrase, 'All right'

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.

Arsenal travel to France to take on Lens in their second Champions League Group B fixture. Mikel Arteta’s side got their European campaign up and running with a convincing home win against PSV Eindhoven in matchweek one, and will hope to take another big step towards the knockout rounds. Lens, making their return to the competition after 20 years away, secured a solid point in Seville in their first fixture, though have endured a difficult start to the new Ligue 1 season. Last year’s runners-up have already lost four times and sit only a point above the relegation places in the French top tier, though back-to-back wins have been a significant boost.

Team news Massadio Haidara has not featured for Lens since suffering a thigh injury in the Champions League opener against Sevilla, joining David Costa (shoulder), Jimmy Cabot and Wuilker Farinez (both ACL) on the sidelines. Mikel Arteta will be fretting over the fitness of Bukayo Saka and Gabriel Jesus, who sustained knocks late on in the win over Bournemouth. Saka trained on Monday but may not be risked with a clash with Manchester City to come at the weekend. Thomas Partey has also been back on the grass as he nears a comeback from his own injury issue, but Gabriel Martinelli (hamstring) would again appear unlikely to feature. Predicted line-ups Lens XI: Samba; Gradit, Danso, Medina; Frankowski, Samed, Mendy, Machado; Fulgini, Sotoca; Wahi.

Liverpool will be sent the audio from Saturday’s offside controversy at Tottenham first before it is released publicly, the PA news agency understands. The club are understood to have requested the audio related to the “significant human error” which led to Luis Diaz’s goal against Spurs being disallowed, having released a statement on Sunday saying they would explore their options given the “clear need for escalation and resolution”. PA understands the goal was not given due to a miscommunication between VAR Darren England and the on-field referee Simon Hooper. Professional Game Match Officials Limited is understood to have always been keen to release the audio in a bid to provide transparency, and that first and foremost it must go to Liverpool. The organisation has not ruled out either airing the audio in the next ‘Match Officials: Mic’d Up’ programme which is scheduled for Monday next week, or possibly sooner than that. England and his assistant VAR, Daniel Cook, have not been included among the officials for duty in the coming weekend’s Premier League fixtures. The pair had already been replaced for the remainder of their Matchweek Seven duties – England was due to be fourth official at Nottingham Forest v Brentford on Sunday, with Cook scheduled to be assistant referee for Monday’s Fulham-Chelsea clash. PGMOL is currently conducting a review of Saturday’s incident. Hooper and his assistants had given offside against Diaz on the field, and the PA news agency understands that although England followed the correct procedure in drawing lines, he lost focus and mistakenly thought the initial on-field decision had been onside. This resulted in him issuing a ‘check complete’ notice to Hooper, rather than advising of an intervention and the goal being awarded. Once the officials realised an error had been made, play had restarted and VAR protocols state that once that has happened, there is no way back to revisit a decision.
