Detail: He lived 1877 to 1946. He calculated black-body-radiation distribution at low and high frequencies {Rayleigh-Jeans radiation, Jeans} {Rayleigh-Jeans law}, with Rayleigh [1900]. All energy seemed to go into higher field frequencies over time, which is impossible {ultraviolet catastrophe, Jeans}: energy density = 8 * pi * k * T / (lambda^4), where T = temperature, k = Boltzmann constant, and lambda = wavelength.
Large-enough {Jeans mass} {Jeans instability} {Jeans length} interstellar clouds can collapse to form stars, depending on temperature, mass, and density.
Two things that can interact share a feature. For example, things that interact gravitationally both have mass. Perhaps, thoughts about perceptions relate to stimulus energies.
