Problems with the steady-state model began to emerge in the 1950s and 60s – observations supported the idea that the universe was in fact changing. Bright radio sources ( quasars and radio galaxies ) were found only at large distances (therefore could have existed only in the distant past due to the effects of the speed of light on astronomy ...
[1]: 26 The model was developed independently by Robert Solow and Trevor Swan in 1956, [2] [3] [note 1] and superseded the Keynesian Harrod–Domar model. Mathematically, the Solow–Swan model is a nonlinear system consisting of a single ordinary differential equation that models the evolution of the per capita stock of capital. Due to its ...

The evidence that resulted in the Big Bang's victory over the steady-state model included discovery of cosmic microwave background radiation in the 1960s, and the distribution of "young galaxies" and quasars throughout the Universe in the 1980s indicate a more consistent age estimate of the universe. Hoyle died in 2001 having never accepted the ...
Uzawa's theorem, also known as the steady-state growth theorem, is a theorem in economic growth that identifies the necessary functional form of technological change for achieving a balanced growth path in the Solow–Swan and Ramsey–Cass–Koopmans growth models. It was proved by Japanese economist Hirofumi Uzawa in 1961. [1]
A steady-state economy is not to be confused with economic stagnation: Whereas a steady-state economy is established as the result of deliberate political action, economic stagnation is the unexpected and unwelcome failure of a growth economy. An ideological contrast to the steady-state economy is formed by the concept of a post-scarcity economy.
George Gamow (1904–1968) argued that observed proportions of hydrogen and helium in the universe could be explained by the big bang model, modeled the mass and radius of primordial galaxies; Margaret J. Geller (1947–) discovered the Great Wall, a superstructure-scale filament of galaxies; Thomas Gold (1920–2004) proposed the steady-state ...
Steady state determination is an important topic, because many design specifications of electronic systems are given in terms of the steady-state characteristics. Periodic steady-state solution is also a prerequisite for small signal dynamic modeling. Steady-state analysis is therefore an indispensable component of the design process.
