New ActivityThe latest activity to be updated on this site is called "Estimate Powers and Roots" (Estimate the powers and roots of the given positive numbers.). So far this activity has been accessed 13450 times and 616 people have earned a Transum Trophy for completing it. 
Learning to estimate powers and roots is important for pupils as it helps develop their problem-solving skills and mathematical reasoning. By being able to estimate the values of powers and roots, students can make quick calculations and approximate results in everyday situations. For example, estimating the square root of a number helps in estimating distances or areas in real-life scenarios.

Recent News:A strange quantum effect could power future electronicsRice University physicists confirmed that flat electronic bands in kagome superconductors aren’t just theoretical, they actively shape superconductivity and magnetism. This breakthrough could guide the design of next-generation quantum materials and technologies. more... Scientists discover forgotten particle that could unlock quantum computersScientists may have uncovered the missing piece of quantum computing by reviving a particle once dismissed as useless. This particle, called the neglecton, could give fragile quantum systems the full power they need by working alongside Ising anyons. What was once considered mathematical waste may now hold the key to building universal quantum computers, turning discarded theory into a pathway toward the future of technology. more... AI finds hidden safe zones inside a fusion reactorScientists have developed a lightning-fast AI tool called HEAT-ML that can spot hidden “safe zones” inside a fusion reactor where parts are protected from blistering plasma heat. Finding these areas, known as magnetic shadows, is key to keeping reactors running safely and moving fusion energy closer to reality. more... Harvard’s ultra-thin chip could revolutionize quantum computingResearchers at Harvard have created a groundbreaking metasurface that can replace bulky and complex optical components used in quantum computing with a single, ultra-thin, nanostructured layer. This innovation could make quantum networks far more scalable, stable, and compact. By harnessing the power of graph theory, the team simplified the design of these quantum metasurfaces, enabling them to generate entangled photons and perform sophisticated quantum operations — all on a chip thinner than a human hair. It's a radical leap forward for room-temperature quantum technology and photonics. more... Half of today’s jobs could vanish—Here’s how smart countries are future-proofing workersAI is revolutionizing the job landscape, prompting nations worldwide to prepare their workforces for dramatic changes. A University of Georgia study evaluated 50 countries’ national AI strategies and found significant differences in how governments prioritize education and workforce training. While many jobs could disappear in the coming decades, new careers requiring advanced AI skills are emerging. Countries like Germany and Spain are leading with early education and cultural support for AI, but few emphasize developing essential human soft skills like creativity and communication—qualities AI can't replace. more... The AI that writes climate-friendly cement recipes in secondsAI researchers in Switzerland have found a way to dramatically cut cement s carbon footprint by redesigning its recipe. Their system simulates thousands of ingredient combinations, pinpointing those that keep cement strong while emitting far less CO2 all in seconds. more... Study deepens understanding of cell migration, important for potential medical advancesA new study integrated mathematical modeling with advanced imaging to discover that the physical shape of the fruit fly egg chamber, combined with chemical signals, significantly influences how cells move. Cell migration is critical in wound healing, immune responses, and cancer metastasis, so the work has potential to advance a range of medical treatments. more... |
