Biology
Photosynthetic Rate Calculator
Calculate a leaf's photosynthetic rate from CO₂ uptake measurements. Used by plant physiologists and agronomists to assess plant health, stress responses, and productivity under varying light or CO₂ conditions.

Biology
Population Growth Rate Calculator
Compute the exponential growth rate r from initial and final population sizes over a time interval, as r = ln(N_final / N_initial) / t. Useful for bacterial cultures, microbial fermentation, cell-culture monitoring, and any closed system in exponential phase.
