New ActivityThe latest activity to be updated on this site is called "Fifteen" (A strategy game. Play against the computer to select three numbers that add up to 15.). So far this activity has been accessed 53854 times and 1805 people have earned a Transum Trophy for completing it. Featured ActivityRoman Numerals Jigsaw This is a wonderful activity for someone who does not know Roman numerals. By completing the activity an understanding of the symbols develops and a great sense of achievement is enjoyed. Recent News:Agriculture tech use opens possibility of digital havocWide-ranging use of smart technologies is raising global agricultural production but international researchers warn this digital-age phenomenon could reap a crop of another kind -- cybersecurity attacks. Complex IT and math modelling has highlighted the risks. more... AI reveals unsuspected math underlying search for exoplanetsThe astronomers' goal: find an artificial intelligence algorithm to interpret microlensing events captured by the upcoming Roman Space Telescope and speed detection of exoplanets around other stars. They achieved that, but the AI told them something unexpected and deep: the theory used to infer stellar and exoplanetary masses and orbits from observations was incomplete. Digging into the mathematics, they uncovered a theory that explains all types of microlensing events and possible ambiguities in interpreting them. more... The numbers don't lie: Australia is failing at maths and we need to find a new formula to arrest the declineAustralia has suffered a significant drop in teenage maths proficiency in the past 20 years -- sliding from 11th in the OECD rankings to 29th place out of 38 countries, prompting widespread debate over potential curriculum changes. One researcher says hand gestures could stop the slide. more... How cells correct errors under time pressureHow does a cell balance risk and speed when dividing? Scientists have developed and experimentally tested the first mathematical theory that describes the cell's best strategy for dividing safely and efficiently. more... Development of an ensemble model to anticipate short-term COVID-19 hospital demandScientists identified the most relevant predictive variables for anticipating hospital demand and proposed using an ensemble model based on the average of the predictions of several individual models. more... An easier way to teach robots new skillsResearchers have developed a technique that enables a robot to learn a new pick-and-place task with only a handful of human demonstrations. This could allow a human to reprogram a robot to grasp never-before-seen objects, presented in random poses, in about 15 minutes. more... Study shows simple, computationally-light model can simulate complex brain cell responsesStudying how brain cells respond to signals from their neighbors can aid the understanding of cognition and development. However, experimentally measuring the brain's activity is complicated. Neuron models provide a non-invasive way to investigate the brain, but most existing models are either computationally intensive or cannot model complex neuronal responses. Recently, a team has used a computationally simple neuron model to simulate some of the complex responses of neurons. more... | Tweets by @Transum |
