The number of bacteria in a culture doubles every hour. If there are initially 200 bacteria, how many will there be after 12 hours?

**Why the number of bacteria in a culture doubles every hour? The surprising math behind exponential growth** Every minute counts when tracking living organisms at the microscopic level. Real-time data reveals that certain bacterial cultures double in number hour after hour—exponential growth that feels almost magical to the outsider. If you start with just 200 bacteria and let them reproduce at a rate doubling every hour, where will that number stand after 12 hours? Understanding this pattern unlocks insight into how tiny organisms shape health, medicine, and everyday biology—especially relevant in a time when science influences daily decisions. **The science behind the doubling: Why it works** Bacterial doubling every hour is not a myth—it’s a well-documented biological phenomenon observed in ideal conditions. Each bacterium divides into two under favorable environments, creating exponential multiplication. This means growth isn’t linear; instead, the population leaps forward rapidly. With 200 starting cells doubling hourly, mathematicians know this doubling process follows a predictable formula rooted in exponential functions: initial count multiplied by 2 raised to the power of time in hours. The precision behind this model makes it a powerful teaching tool and subject of growing public interest in biology and health trends.
