In a Heath Robinson device, everything has a clear purpose, no matter how strange it appears. For example, there is a clearly discernable logic to the profusion of cables, pulleys and bellows in his “Spare Room,” above, from this year’s HR calendar. It may not be realistic — I wouldn’t want to sleep in that bed — but everything makes sense. (The same is true of the inventions of Heath Robinson’s American counterpart, Rube Goldberg.) Comparing Neil Ferguson’s incomprehensible mathematical model to a Heath Robinson device slanders Robinson.
