Math Monday: Mathematical Models from a Chemistry Kit
The little metal connectors and plastic tubes that chemistry students sometimes use to make chemical models can also be used to make interesting geometric models.
Math Monday: Make a Truchet Tiles Puzzle
Create laser-cut Truchet tiles that can be rearranged in a frame into many interesting patterns.
Math Monday: Large Stars
Here is a simple way to make the small stellated dodecahedron on a large scale.
Math Monday: Passing a Cube Through Another Cube
It is an amazing fact that it’s mathematically possible to pass a cube through a hole in another cube of the same size. If you stand a cube up on a corner (with a diagonal vertical) and shine a light down on it, its shadow is a regular hexagon. If you calculate carefully, you’ll find that a square face of the cube can fit inside this hexagon with a bit of room to spare on all sides.
Vi Hart and More Fun with Fibonacci, Plants, and “Spiraly Things”
Here are parts two and three of Vi Harts’ brilliant and dizzying exploration of the Fibonacci number, plant growth patterns, and the mathematics behind other cool, spiraly things.
Math Monday: Mathematical Quilting
By George Hart for the Museum of Mathematics Quilting is one of the everyday activities in which people use mathematics without necessarily realizing it. Geometric thinking is required to make any modular quilt pattern, but some quilters also choose mathematical subject matter for their quilts. This quilt by Camilla Fox shows a symmetric pattern constructed […]
