For the second time in a week, a long-standing conjecture has been disproved by artificial intelligence, highlighting the ...

Math difficulty is still not well understood. But a systems approach may lead to advances in diagnosis and treatment.

How can you have a proof without proving anything? Mathematicians found a way and, in the process, came to blows over it – but 100 years on, this trick is a common part of modern maths, says columnist ...

In order to solve these problems, this paper proposes a negative Poisson's ratio metamaterial filled structure based on topology optimization. Firstly, a functional cell element topology optimization ...
