家园 bacteria

"Some bacteria live in a bottle. Their population doubles every minute. At 11 am there is one bacteria. At 12 noon the bottle is full, At 11:59 it is half full leaving only enough space for one more doubling. The bacteria see the danger and they search for new bottles and find three. They assume their problem is solved. By 12 noon the first bottle is full, by 12:01 the second bottle is full. By 12:02 all the bottles are full. This is the problem we face due to the idea of exponential growth.
