Wheels in Flatland This latest work pioneers the investigation of constant-width shapes in any dimension, but designing wheels in two or three dimensions is itself not a new problem.

The study investigated the strategies that 7- to 12-year-old children spontaneously apply to the solution of novel combinatorial problems. The children were individually administered a set of six ...

So when you refer to vectors by scalar components you have to give the coordinate system too. Dealing with vectors in three dimensions is more complicated. In the component representation, there are ...

In this way, they were finally able to prove the Kakeya conjecture in three spatial dimensions, showing that the volume covered by the needle is always three-dimensional.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Geometric problem solving - Higher Geometric problems can be solved using the rules for adding and subtracting vectors and multiplying vectors by a scalar .

When solving the one-dimensional cutting stock problem (1D CSP) as an integer linear programming problem one has to overcome computational difficulties arising from the integrality condition and a ...

Understanding our profile when it comes to problem-solving and recognizing our mindset can be the first step to avoiding getting stuck in problems without reaching a solution. Here are three of ...
