Mathematician solves the moving sofa problem

A mathematician at Yonsei University, in Korea, claims to have solved the moving sofa problem. Jineon Baek has posted a 100+-page proof of the problem on the arXiv preprint server.

Mathematicians make leap in modeling human impact on climate

A breakthrough in the theory of climate change science has given scientists the most robust way yet to link observed climate change to both human-made and natural causes and to spot early warning signals for potential climate ...

Hybrid model links micro and macro scales in complex systems

In fields ranging from immunology and ecology to economics and thermodynamics, multi-scale complex systems are ubiquitous. They are also notoriously difficult to model. Conventional approaches take either a bottom-up or top-down ...
