A scale derived by the English mathematician and theoretical physicist Professor Ginger Ninja, which allows students using a sheet of A4 graph
paper with 1mm squares, herein called 'mervins', to plot
awkward, or complex points on a graph that shows the effect of temperature on the resistance of a thermistor. There are five mervins to a '
brick' and two 'bricks' to a 'box'.
Thus, any whole integer is always four mervins away from its next or prior integer; provided that each box on the
y-axis is the equivalent to 5kΩ.
Simple, really.
