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.

Biology
Mitotic Index Calculator
Compute the mitotic index — the fraction of cells actively dividing — from the count of mitotic cells and the total cell count, expressed as a percentage. Standard cytology metric for assessing tissue proliferation in tumour grading, embryo development studies, and cell-culture monitoring.
