In this module, we will discuss the dynamics of exponentials and their counterparts power laws that represent a power relation between two entities. • Part of our definition for linear systems is that the relationship between input and output is related in a linear fashion, the ratio of input to output might be 2 times as much, 10 times as much or even a thousand times it is not important this is merely a quantitative difference, what is important is that this ratio between input and output is itself not increasing or decreasing. But as we have seen when we have feedback loops the previous state to the system feeds back to effect the current state thus enabling the current ration between input and output to be greater or less than its ratio previously and this is qualitatively different. • This phenomenon is captured within mathematical notation as an exponential. The exponential symbol describe how we take a variable and we times it by another not just once but we in fact iterate on this process, meaning we take that output and feed it back into compute the next output, thus the amount we are increasing by each time itself increases. So lets take a quick example of exponential grow to give you an intuition for it. • Say I wish to create a test tube of penicillin bacteria. Knowing that the bacteria will double every second, I start out in the morning with only two bacteria hoping to have my tube full by noon. As we know the bacteria will grow exponentially as the population at any time will feed into effect the population at the next second, like a snowball rolling down a hill. It will take a number of hours before our tube is just 3% full but within the next five seconds as it approaches noon it will increase to 100% percent of the tube... • Learn about the Systems Innovation Network on our social media: • → Twitter: http://bit.ly/2JuNmXX • → LinkedIn: http://bit.ly/2YCP2U6
