New ActivityThe latest activity to be updated on this site is called "Huge Numbers" (Carry out calculations with numbers up to one million including strategies to check answers.). So far this activity has been accessed 53 times and 4 people have earned a Transum Trophy for completing it. 
Being confident with huge numbers is a superpower! You’ll see big numbers everywhere: in the news, on social media, in science, sport, money and even video games. Whether it’s the distance to the Moon, the number of views on a video, or how much money a footballer earns, huge numbers are part of the real world.

Recent News: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... In nature's math, freedoms are fundamentalScientists have developed a unified theory for mathematical parameters known as gauge freedoms. Their new formulas will allow researchers to interpret research results much faster and with greater confidence. The development could prove fundamental for future efforts in agriculture, drug discovery, and beyond. more... A chip with natural blood vesselsMiniature organs on a chip could allow us to do scientific studies with great precision, without having to resort to animal testing. The main problem, however, is that artificial tissue needs blood vessels, and they are very hard to create. Now, new technology has been developed to create reproducible blood vessels using high-precision laser pulses. Tissue has been created that acts like natural tissue. more... A faster, more reliable method for simulating the plasmas used to make computer chipsResearchers developed a faster, more stable way to simulate the swirling electric fields inside industrial plasmas -- the kind used to make microchips and coat materials. The improved method could lead to better tools for chip manufacturing and fusion research. more... AI is good at weather forecasting. Can it predict freak weather events?Scientists found that neural networks cannot yet forecast 'gray swan' weather events, which might not appear in existing training data but could still happen -- like 200-year floods or massive hurricanes. more... |
