I am reading Robert Solow's 1956 paper, entitled 'A Contribution to the Theory of Economic Growth'. I am trying to understand the economic interpretation of the differential equation $$\dot{K}=sY(t),$$ which is located on page 67 (Solow denotes this equation by $(3)$). I have understood each term as: $s$ is the proportion of saved output, $Y(t)$ is the production function at time $t$, and $\dot{K}$ is the rate of increase of capital stock with respect to time $t$. Although, I am having trouble understanding what this equation actually means (I am a novice at economics).
