Threaded Theorems

In the plot, each compartment is shown as a curve over time. The susceptible curve starts high and declines as individuals become infected. At the same time, the infectious curve rises, creating an epidemic peak. Once the susceptible population drops below a critical threshold, and as infectious individuals recover, the infectious curve begins to fall. Meanwhile, the recovered curve steadily increases and eventually plateaus, reflecting that most of the population has passed through infection.

Sneak peek of a new maths embroidery design 🤠

This embroidery design illustrates the Lotka–Volterra model, a mathematical system that describes how predator and prey populations interact over time. The horizontal axis shows prey numbers and the vertical axis shows predator numbers. Each curved loop represents a repeating cycle of population changes. 🐰 Embroidery template available on my website 🦊

This full binary tree branches out over 8 levels 🌿✨, stitched with stem stitch and dotted with French knot leaves. Who knew recursion could look so cute? Template in my blog description if you want to stitch your own!

Work in progress of a binary tree.

The Koch snowflake is a fractal made by repeatedly adding smaller triangles to the middle of each edge of an equilateral triangle. Every iteration, each edge turns into four edges that are a third as long, which makes the perimeter grow by a factor of 4/3. Keep repeating this forever and the perimeter becomes infinite! But, even though you keep adding more and more tiny triangles, the extra area you add each iteration gets smaller and smaller. This means the total area settles down and approaches a finite value - 1.6 times the area of the original triangle. So the Koch snowflake has an infinite perimeter and a finite area!

This embroidery recreates the first published image of the Mandelbrot set from 1978, using thread to capture its striking symmetry and spiky outline. The Mandelbrot set is a famous fractal formed by repeatedly applying an iterative equation​ to the complex numbers. Each complex number can be represented as a point on a 2D plane. If the results of the iterative equation starting at a specific point stay bounded, the point is in the Mandelbrot set. Points outside the set are generally coloured based on how fast they escape, forming the fiery fringes around the edge.

In this regime, everything moves smoothly and predictably, like a billiard ball sinking into syrup. The closer the lines, the faster the flow. Far away, the sphere’s influence fades, and the lines stretch out to be uniform. [Free embroidery template]
