Vortex Dome STEM Desk Toy - Handmade in the UK by David Fowler

Product Information

A direct simulation of a Rheoscopic fluid would entail modelling each particle, their alignment with the shear direction and a lighting model that calculated the optical behaviour for each particle in the context of the ‘view from’ location. Assuming an average particle size of 1x10x100 micron, knowing the density of mica and the total mass of mica particles, there are about 1785714286 mica particles present in the dome (roughly 😉 ). Modelling ~2 billion particles is quite intractable, at least on my laptop.

Here are some of the attributes that were valued in the old, traditional mindset, often referred to as fixed mindset, and, in comparison, what these new times are calling for in the 21st century, the growth mindset. The comfort zone, or status quo, is no longer viable as a modern business stance. 20th Century Leadership Mindset Menter, F.R.; Kuntz, M.; Langtry, R.

Only remaining question is where in the dome to plot its distribution and evolution? I have chosen a curved plane 1.5mm inset from the top dome surface as a kind of mid way point of how ‘deep’ into the particle laden flow one can see. The absolute value of the vorticity does not matter, just its relative distribution, so the colour map used to plot it is normalised to the min/max extents at each time step.
