Your own virtual heart for non-invasive heart diagnostics

Credit: Ecole Polytechnique Federale de Lausanne EPFL mathematician Alfio Quarteroni and his team are building a virtual heart model based on personalized medical images that may one day help cardiologists and cardiac surgeons non-invasively diagnose pathological heart conditions. The team recently modeled and simulated the behavior of a patient’s aortic valve. One day, a virtual…

Malcolm Swan obituary

My friend and colleague Malcolm Swan, who has died aged 64 of a brain tumour, was a driving force in the international movement to improve the teaching of mathematics. Malcolm’s exceptional skill lay in the design of materials that enable maths teachers to turn research insights into happy learning in their classrooms. He did this…

Finding mental disorders with math

Eccentric French maths genius's 'scribblings' go online

Nearly 18,000 pages of notes by eccentric French maths genius Alexandre Grothendieck were posted online Wednesday by his alma mater, Montpellier University in southern France. Grothendieck, who died aged 86 in 2014, “revolutionised an entire area of mathematics, algebraic geometry,” said Jean-Michel Marin, head of an institute that bears the mathematician’s name at the university.…

Did artists lead the way in mathematics?

Is there a geometry lesson hidden in ‘The Last Supper’? Credit: Wikimedia Commons Mathematics and art are generally viewed as very different disciplines – one devoted to abstract thought, the other to feeling. But sometimes the parallels between the two are uncanny. From Islamic tiling to the chaotic patterns of Jackson Pollock, we can see…
