The accurate equations to determine the temperatures optimizing the efficiencies of blackbody radiation η(λ,T) and η(λ1, λ2, T) have been derived. The relation between Wien's law λmT = 2897.8 μm · K and the equation first derived in this paper λTm = 3669.7 μm · K is ...
Analytical Derivation of the Exponent Factor n in the Extended Tn Relation of Radiance for Thermal Radiation:Derivation from Planck's Law After chorionic villus biopsy of human placenta, cell cultures were propagated with Ham's F10 medium or Eagle's minimum essential medium (MEM). It was poss....
The Planck spectrum including zero-point radiation seems to satisfy a natural maximum-uniformity principle for Casimir energies whereas alternative choices of spectra do not. Specifically, we consider a set of identical conducting-walled boxes at the same temperature, but each has a conducting ...
Planck TimeHubble ConstantPurpose: The cosmic microwave background radiation, CMB, is fundamental to observational cosmology, and is believed to be a remnant from the Big Bang. The CMB, Planck time, tP, and the Hubble constant, H0, are important cosmologic constants. The goal is to accurately...
