The first validation of the Lillo Mike Farmer Model on a large financial market dataset Economics and physics are distinct fields of study, yet some researchers have been bridging the two together to tackle complex economics problems in innovative ways. This resulted in the establishment of an interdisciplinary research field, known as econophysics, which specializes in solving problems rooted in economics using physics theories and experimental methods. https://phys.org/news/2023-11-validation-lillo-mike-farmer-large.html Mathematics Economics & Business Thu, 30 Nov 2023 09:56:53 EST news620560608 Coping with uncertainty in customer demand: How mathematics can improve logistics processes How do you distribute drinking water fairly across an area recently hit by a natural disaster?

What if finding the solution to a problem took almost a century? For mathematicians who dabble in Ramsey theory, this is very much the case. In fact, little progress had been made in solving Ramsey problems since the 1930s. https://phys.org/news/2023-10-math-problem-century.html Mathematics Tue, 31 Oct 2023 14:45:03 EDT news617982301 Improved information and communication technology infrastructure leads to better math skills, research suggests Students who are more digitally skilled also perform better in math. New research from Renae Loh and others at Radboud University shows that in countries with better availability of information and communication technology (ICT) in schools, math performance benefits greatly. It further suggests that improving the ICT environment in schools can reduce inequality in education between countries.
