New ActivityThe latest activity to be updated on this site is called "Geometric Sequences" (An exercise on geometric sequences including finding the nth term and the sum of any number of terms.). So far this activity has been accessed 17275 times and 2786 people have earned a Transum Trophy for completing it. 
It is important for pupils to learn about geometric sequences in maths as it helps develop their understanding of patterns and relationships between numbers. By studying geometric sequences, students can enhance their problem-solving skills, critical thinking abilities, and logical reasoning. Featured ActivityKey Stage 2 Tests There are some wonderful questions for Year 6 pupils in the Key Stage 2 Maths Tests (SATs) which normally take place at this time each year. Here are some links to Transum activities for the main Maths attainment statements. Click the image above to begin. Recent News:New AI method tackles one of science’s hardest math problemsPenn researchers have developed a smarter AI method for solving notoriously difficult inverse equations, which help scientists uncover hidden causes behind observable effects. By introducing “mollifier layers” that smooth noisy data, they’ve made these calculations more stable and far less computationally demanding. This could transform fields like genetics, where understanding how DNA behaves is key to disease research. more... Scientists just captured a mysterious quantum “dance” inside superconductorsIn a breakthrough experiment, scientists directly imaged how particles pair up in a system that mimics superconductors. Instead of behaving independently, the pairs moved in a synchronized, dance-like pattern—something never predicted before. This suggests a major gap in the classic theory of superconductivity. more... This donut-shaped discovery just shattered a 150-year math ruleA 150-year-old rule in geometry has been proven wrong. Mathematicians found two different doughnut-shaped surfaces that look identical when measured locally but are actually different overall. For decades, researchers suspected this might be possible but couldn’t prove it—until now. The breakthrough reshapes how mathematicians understand the relationship between local measurements and global form. more... This simple change stops robot swarms from getting stuckIn crowded environments, more robots don’t always mean faster results—in fact, too many can bring everything to a standstill. Harvard researchers discovered a surprising fix: adding a bit of randomness to how robots move can actually prevent gridlock and boost efficiency. By allowing robots to “wiggle” slightly instead of marching in straight lines, they can slip past each other and keep tasks flowing smoothly. more... New light trap design supercharges atom-thin semiconductorsScientists have found a clever way to supercharge ultra-thin semiconductors by reshaping the space beneath them rather than altering the material itself. By placing a single-atom-thick layer of tungsten disulfide over tiny air cavities carved into a crystal, they created miniature “light traps” that dramatically boost brightness and optical effects—up to 20 times stronger emission and 25 times stronger nonlinear signals. These hollow structures, called Mie voids, concentrate light exactly where the material sits, overcoming a major limitation of atomically thin devices. more... Scientists built the hardest AI test ever and the results are surprisingAs AI systems began acing traditional tests, researchers realized those benchmarks were no longer tough enough. In response, nearly 1,000 experts created Humanity’s Last Exam, a massive 2,500-question challenge covering highly specialized topics across many fields. The exam was engineered so that any question solvable by current AI models was removed. Early results show even the most advanced systems still struggle — revealing a surprisingly large gap between AI performance and true expert-level knowledge. more... A tiny twist creates giant magnetic skyrmions in 2D crystalsTwisting atomically thin magnetic layers does more than reshape their electronics—it can create giant, topological magnetic textures. In chromium triiodide, researchers observed skyrmion-like patterns stretching far beyond the expected moiré scale, reaching hundreds of nanometers. Even more surprising, their size doesn’t simply follow the twist pattern but peaks at a specific angle. This twist-controlled magnetism could pave the way for low-power spintronic devices built from geometry alone. more... |
