Question
This property names a method for hard boiling eggs published by Di Lorenzo et al. 2025. For 10 points each:
[10m] Give this property possessed by both functions that can be represented as Fourier series and the trigonometric functions summed in Fourier series. Bloch's ("block's") theorem describes wavefunctions in potentials with this property.
ANSWER: periodic [prompt on sinusoidal] (The publication is "Periodic cooking of eggs.")
[10e] Fourier series were pioneered to study this thermodynamic quantity's namesake PDE. This form of energy, denoted "Q," equals m c delta-T.
ANSWER: heat energy [prompt on thermal energy]
[10h] Di Lorenzo et al. model this quantity via distinct affine functions of temperature for egg white versus yolk. Fourier names the statement that heat flux equals this quantity times the negative gradient of temperature.
ANSWER: thermal conductivity [prompt on k or kappa or lambda]
