Simon wrote these two “formulas” to explain how time (T1) works in one second (S2) of fast and slow motion film. S1 is “sneller” (Dutch for “faster”) T2 is “trager” (Dutch for “slower”). Hence one second of fast motion film shown at normal speed is going to take longer than one second and one second of slow motion film shown at normal speed is going to take less than one second.
Simon says that it’s easier for him to write things down this way instead of with sentences because otherwise “his fingers get tired of writing”.
