Final Look at 2019: School, Science and Education

by Frederick Koh*A detailed review of 2019 examining science, school and education related events.*

Hypot – A story of a ‘simple’ function

by Mike Croucher*Even the most simple looking mathematical functions can be difficult to implement on computers perfectly. In this post, I look at an extremely common computation where the mathematics can be understood by children and yet efficient and bug-free implementation is complex and the subject of modern research.*

Convergence rate of random walks

by John Cook*In some cases, random walks rapidly become more uniformly distributed, quickly going from obviously not uniform to apparently uniform.*

Attracted to Attractors

by Ari Rubinsztejn*In this post 3 different chaotic attractions are visualized.*

More Modular Knitting

by Pat Ashforth*Geometry in knitting (even for those who ‘can’t do maths’). How many different shapes can be knitted using only 45, 90 and 135 degree angles?*

The Multiples of Me

by Sam Hartburn*The Multiples of Me is a poem about prime numbers, and why they needn’t be sad about having no factors.*

Two dimensional tessellations at the Curious Minds Club

by Debbie Pledge*I run a recreational maths after school club in England. The post shows I got the children to explore the regular and semi-regular tessellations.*

Australian Mathematicians

by LThMath*At the start of January we wanted to do something on our Facebook page to raise awareness about all the problems Australia has been through in the last period. We were shocked at the situation there. For 2 weeks we researched and wrote more about Australian mathematicians and their work. In addition, each post has a link where you can donate for different charities and organizations. In this post we want to put together all the information we have discovered in those 2 weeks, including the mathematicians and where you can still donate to help.*
