New ActivityThe latest activity to be updated on this site is called "Changing Times" (A self-marking exercise on converting between time units, from seconds and minutes to months and years.). So far this activity has been accessed 41 times and 7 people have earned a Transum Trophy for completing it. 
You use these skills in real life all the time, even when you don’t notice it. You read clocks, catch buses, follow timetables, cook food, measure how long something takes, and work out when to start if you need to be somewhere on time. Changing Times helps you get really confident with all the different ways time can be written, like seconds, minutes, hours, and mixed formats. Once you can switch between them easily, everyday problems start to feel much simpler and less stressful. Featured ActivityNewsletter The Transum Newsletter for March 2026 has just been published.

Recent News: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... Brain inspired machines are better at math than expectedNeuromorphic computers modeled after the human brain can now solve the complex equations behind physics simulations — something once thought possible only with energy-hungry supercomputers. The breakthrough could lead to powerful, low-energy supercomputers while revealing new secrets about how our brains process information. more... Scientists create smart synthetic skin that can hide images and change shapeInspired by the shape-shifting skin of octopuses, Penn State researchers developed a smart hydrogel that can change appearance, texture, and shape on command. The material is programmed using a special printing technique that embeds digital instructions directly into the skin. Images and information can remain invisible until triggered by heat, liquids, or stretching. more... Scientists discover hidden geometry that bends electrons like gravityResearchers have discovered a hidden quantum geometry inside materials that subtly steers electrons, echoing how gravity warps light in space. Once thought to exist only on paper, this effect has now been observed experimentally in a popular quantum material. The finding reveals a new way to understand and control how materials conduct electricity and interact with light. It could help power future ultra-fast electronics and quantum technologies. more... How everyday foam reveals the secret logic of artificial intelligenceFoams were once thought to behave like glass, with bubbles frozen in place at the microscopic level. But new simulations reveal that foam bubbles are always shifting, even while the foam keeps its overall shape. Remarkably, this restless motion follows the same math used to train artificial intelligence. The finding hints that learning-like behavior may be a fundamental principle shared by materials, machines, and living cells. more... This AI spots dangerous blood cells doctors often missA generative AI system can now analyze blood cells with greater accuracy and confidence than human experts, detecting subtle signs of diseases like leukemia. It not only spots rare abnormalities but also recognizes its own uncertainty, making it a powerful support tool for clinicians. more... These mesmerizing patterns are secretly solving hard problemsTessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly reflecting shapes to tile a surface, researchers uncovered a method that links geometry, symmetry, and problem-solving. The technique works in both ordinary flat space and curved hyperbolic worlds used in theoretical physics. Its blend of beauty and precision could influence everything from engineering to digital design. more... |
