  1. Uhhh, wouldn't that be s*x?

    And then...more s*x?


  2. better health services and better technology allow for less infant deaths, longer life span, less dependency on natural processes.

    but lack of cultural change, especially in developing countries, and in countries with strong religious influence, prevented change in customs concerning number of children per family.

  3. Exponential s*x.

  4. The number of offspring and the number of deaths is proportional to the existing population. So, the change in population is proportional to the population. This is a standard differential equation:

    dn/dt = a*n

    a=birthrate-deathrate

    n(t)=n(0)*exp(a*t)

    Note that it is exponential whether "a" is negative or positive. So, if the death rate exceeds the birth rate, you will have an exponential decay in population.

  5. Public health projects that safely treat sewage and provided clean drinking water, along with cheap vaccines for many common diseases greatly reduced death rates, especially of children.

    More productive farming methods with high yield crops and irrigation greatly increased the food supply.
