Stirring the Porridge with Albert E (top view), glass plates and UV sensitive pigments, 4 × 4 × 6.5 inches, 2017. 2 Jamie Lochhead, Inside Einstein’s Mind, BBC4/WGBH Educational Foundation, 2015. 000, 2019 523 References and Notes 1 By definition, if nothing else, this work is also photography: photos + graphos-drawing with light.

(The porridge is also a good analogy for the distance between my brain’s lumpen-ness and Albert’s cosmic musings.) It is also, I hope, a serious, if playful, representation of a specific spacetime (Figs 1–3, Color Plate D). On one level, this glass structure is a model of his experiment, conceived from the banality of cooking breakfast. This would create a 3D map of a continuum of space through time and illustrate their combined nature (Color Plate D). In this experiment Einstein visualized cutting cine film into single frames and placing the individual pictures, in sequence, one on top of the other. In particular it described the early-1900s gedankenexperiment that led him to conclude that time and space are two aspects of one thing, which he called raumzeit (spacetime). The third impetus that led to me making this object was an illuminating film about Einstein and his work. Thinking about this as I stirred away at the porridge, it seemed to me that if I considered the tip of the spoon as the particle and the spiral motion of the spoon through time as the wave, maybe I was beginning to visualize the concept a little more clearly (Fig. particle-refraction via lens or wave-diffraction via pinhole). I had experienced, but not fully understood, the puzzling way that light behaves both as a particle and a wave (e.g. The resulting friendship had given energy to my longstanding desire as a photographer to understand more fully the nature and behavior of light. Around this time I had been fortunate enough to meet the artist and physicist Jacques Mandelbrojt. I was idly trying to work out the most efficient way to stop it sticking to the pot and had decided (as I’m sure have many others) that spiraling inward to the center and then outward to the side seemed the best technique. it started when I was stirring the porridge. In lieu of an abstract, here is a brief excerpt of the content:
