A spiral of dancing triangles…just because.Continue reading Dancing Triangles: Sunday Maths Animations Week 9
And what does that have to do with maths?
A little while ago, Abs Pascoe (who I highly recommend if you’re thinking of starting singing lessons and you happen to live near Whitstable) posted this amazing video where she sings two different notes at once. I had never heard anything like it before! My first thought was that it was some kind of dark magic. My second thought was that there must be some interesting maths going on there.Continue reading Can You Sing Two Notes at Once?
Earlier this week I was proofreading a book that mentioned Pythagorean spirals. I had seen them before but never thought about them too deeply, so I gave them a try in GeoGebra. I filled them in with curves of pursuit, just for fun!Continue reading Pythagorean Spiral meets Pursuit Curves: Sunday Maths Animations Week 8
Week 7 of my Sunday Maths Animations is another one that started out as a cardioid. Varying a different parameter gives a completely different effect.Continue reading More Cardioid Rainbows: Sunday Maths Animations Week 7
Week 6 of my Sunday Maths Animations started out as a cardioid, but quickly became something else.Continue reading Cardioid Rainbow: Sunday Maths Animations Week 6
Week 5 of my Sunday Maths Animations is a Pythagorean tree, drawn point by point.Continue reading Pythagorean Tree: Sunday Maths Animations Week 5
Week 4 of my Sunday Maths Animations is my old favourite the Rhodonea curve, rendered with spheres. The ending is extremely satisfying!Continue reading Rhodonea Spheres: Sunday Maths Animations Week 4
Week 3 of my Sunday Maths Animations grew from a puzzle at February’s MathsJam that involved calculating the shaded area in a shape involving infinitely recursing circles. Can you tell which circles are changing in size and which are staying the same?Continue reading Infinitely Zooming Circles: Sunday Maths Animations Week 3
For week 2 of my Sunday animations I’ve stuck with circles, this time on a harmonograph curve (which is a relation of the Lissajous curves).Continue reading Circles on a Harmonograph Curve: Sunday Maths Animations Week 2
I’ve been enjoying making animations in Geogebra recently, and have decided to try publising one every week on YouTube. Here is week 1.Continue reading Circles on a Lissajous Curve: Sunday Maths Animations Week 1
