New ActivityThe latest activity to be updated on this site is called "Speed Skills" (Practise your skills finding either the speed, distance or time given the other two values.). So far this activity has been accessed 96 times and 31 people have earned a Transum Trophy for completing it. 
You use speed without even thinking about it: how fast you walk, how long a car journey will take, or whether you will make it on time. This activity helps you get really good at the simple idea that speed is “distance divided by time”, and how to rearrange that to find distance or time when you need to. Featured ActivityTriangle Solver This simple calculator will work out the lengths of the sides and the size of the angles of any triangle given thee particular pieces of information. Recent News: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... This AI finds simple rules where humans see only chaosA new AI developed at Duke University can uncover simple, readable rules behind extremely complex systems. It studies how systems evolve over time and reduces thousands of variables into compact equations that still capture real behavior. The method works across physics, engineering, climate science, and biology. Researchers say it could help scientists understand systems where traditional equations are missing or too complicated to write down. more... |
