Our daily assemblies are uncensored, open forums in which anyone is free to offer a contrary or controversial perspective, opinion or rant. This morning's meeting featured both Nelson Lebo and Lee Carvalho defending the notion that anti-war sentiments may be held by individuals who are--still--true patriots. This is also "population control week," which is appropriate because Proctor's student population has grown over the years, and it is a controversial matter for many. Lee shed light on things by explaining the mathematical Rule of 70: if you divide 70 by any growth rate, you get the amount of time till the population doubles.
In our case, with 1.3% annual growth (I'm speaking about the globe now,) our 6.25 billion will double in 54 years. Meanwhile, Proctor's day student population has more than doubled since I got here, which I think is great.
Below, students in biology observe the exponential growth curve (red) of human population over the ages.
