New ActivityThe latest activity to be updated on this site is called "Bottles, Boxes and Cans" (Estimate the capacity of the bottles, boxes and cans in the photograph and answer questions about volume.). So far this activity has been accessed 21236 times and 3369 people have earned a Transum Trophy for completing it. 
In order to estimate the capacity of the bottles, boxes, and cans in the photograph, you would need to determine the volume of each object. Volume is a key concept in mathematics that helps in understanding the amount of space an object occupies. In this case, it would help in estimating the amount of liquid that can be contained in the bottles, boxes, and cans. Featured ActivityLemon Law A fascinating digit changing challenge. Change the numbers on the apples so that the number on the lemon is the given total. Can you figure out, by understanding place value, how this works? Recent News:Cambridge scientists create a $10 chip that could put a medical lab on your wristCambridge researchers have created a groundbreaking $10 optical sensor that delivers the precision of laboratory equipment in a device small enough for wearable technology. It identified foods, plastics, and medicines with 100% accuracy in tests and demonstrated the ability to monitor blood glucose, alcohol, and other health markers without invasive procedures. more... Physicists discover “astonishing” property of light that defies expectationsScientists have uncovered a surprising hidden ability of light that allows it to develop spinning, twisting behavior as it travels through empty space, without special lenses, mirrors, or materials. Researchers discovered that light’s internal geometry can naturally produce left- and right-handed patterns, challenging long-standing assumptions about how light behaves. By carefully arranging a beam’s structure, scientists can control where and how these spinning patterns emerge, unlocking a new way to manipulate light. more... Scientists recreate a bizarre quantum effect that stops a particle coldOxford physicists have recreated a bizarre quantum effect in which a particle responds to a magnetic field without ever traveling through it. Using a hybrid quantum computer, they demonstrated how introducing a simulated magnetic flux could completely halt a particle's movement through quantum interference. The experiment brings a decades-old prediction into a new setting where matter and quantum fields influence one another. more... The hidden math of Alzheimer's could point to new treatmentsMathematics may hold unexpected clues to understanding Alzheimer’s disease. Scientists have developed a model showing how common metals like copper and zinc may influence the buildup of proteins associated with the disease, while also exploring possible ways to stop the process. The findings could help researchers identify promising strategies for preventing harmful plaque formation. more... This new qubit could be 100 times less error-prone in superfluid quantum computer breakthroughA proposed qubit made with superfluid helium could cut quantum computing error rates by around 100 times by shielding quantum information from common forms of electromagnetic noise. If experiments confirm the predictions, the technology could eventually work alongside today’s superconducting qubits or serve as a new kind of quantum memory. more... Caltech physicists finally measure a quantum energy ladder predicted 40 years agoResearchers have experimentally observed energy patterns that physicists have predicted for about 40 years. By arranging laser-trapped atoms into a quantum simulator, they recreated two different quantum tipping points and watched the atoms fall into the exact energy ratios predicted by theory. The technique could now be used to explore mysterious quantum systems where scientists do not already know the answer. more... Scientists find that “perfect” systems may be surprisingly fragileComplex systems may work better when their parts are not perfectly alike. Northwestern physicists found that carefully balanced variation, or “disorder,” can make networks such as power grids, ecosystems, neurons, and materials more stable. Even random differences sometimes improved stability compared with completely uniform systems. The discovery could help researchers design more resilient technologies and explain why natural systems are so rarely perfectly uniform. more... |
