Pythagoras' theorem found on tablet that is 1,000 years older than Pythagoras himself
Pythagoras' theorem found on tablet that is 1,000 years older than Pythagoras himself
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.

Solar panel breakthrough could supercharge ‘miracle material’ production
Solar panel breakthrough could supercharge ‘miracle material’ production
Scientists have made a major breakthrough with a new type of solar panel that they claim could supercharge the transition to renewable energy sources. A team from the University of Surrey discovered that a nanoscale “ink” coating could improve stability enough to make next-generation perovskite solar cells suitable for mass production. Perovskite is cheaper and lighter than conventional silicon-based cells, as well as far more efficient, however the emerging technology currently suffers from a drop in efficiency and energy output during the manufacturing process. “Performance limits of traditional solar cells are why researchers are switching to examining perovskite as the next-generation solar technology, especially as applications both terrestrial and in space are rapidly growing,” said Dr Imalka Jayawardena from the University of Surrey’s Advanced Technology Institute (ATI). “Our key development in solar panel technology shows a cost-effective approach to scaling of perovskite solar cells, a development which could help countries around the world to reach their net zero targets faster.” The breakthrough was made when the researchers identified an aluminium oxide that minimises the drop in efficiency during the conditioning of perovskite solar cells. Perovskite has been hailed as a “miracle material” for its potential to transform an array of industries, from ultra high-speed communications to renewable energy. Recent advances have seen it used to create self-healing solar panels that can recover 100 per cent of their efficiency after being damaged by radiation in space, as well as break new efficiency records when combined with silicon to form tandem cells. If the cheap-to-produce perovskite cells can be manufactured at scale while retaining their durability and reliability, then the cost of solar panels would plummet. “Solar and wind energy costs are rapidly decreasing based on technology improvements, to the level where worldwide over 80 per cent of all new additional power generation capacity is based on renewables,” said Ravi Silva, from the ATI, University of Surrey. “The levelized cost of solar electricity is now cheaper than most other power-generating sources. With the maturing of perovskite solar modules, the levelized cost of electricity will significantly decrease further, and that is why this is such an exciting area to work.” The research was detailed in a study, titled ‘Modification of Hydrophobic Self-Assembled Monolayers with Nanoparticles for Improved Wettability and Enhanced Carrier Lifetimes Over Large Areas in Perovskite Solar Cells’, published in the peer-reviewed scientific journal Solar PRL.
