COMPLEXITY: Physics of Life

Humans, like any other organism, occupy a niche — a “Goldilocks Zone” for which our biology is suited, relatively to the extreme diversity of habitats on Earth. But to understand the natural habitat of human beings we would first have to perform a comprehensive survey of human settlements throughout history and prehistory, looking for patterns in the climate data. No one did this research until very recently, and what they found surprised them...

If COVID-19 has made anything obvious to everyone, it might be how the very small can force the transformation of the very large. Disrupt the right place in a network and exponential changes ripple outward: a virus causes a disease that leads to economic shocks and other social impacts that, in turn, re-open urban spaces to nonhuman animals and change the course of evolution...

It takes effort to embrace complexity. Simple models, simple narratives seem easier up front, their consequences only obvious in retrospect. When we talk about COVID-19 transmission rates, we’re using averages that do not offer crucial insights into how those rates may vary. When we target complex ailments with silver-bullet pharmaceuticals, we don’t address the underlying systems-level problems...

COVID-19 has delivered an extraordinary shock to our assumptions, be they in how we practice education, business, research, or governance. When we base forecasts on bad data, even solid logic gives us unreliable results. Centralized authority is good for organized coherent action but isn’t agile or fine-grained enough to deal with local variance and rapidly evolving novel challenges. Surveillance can save lives but also threatens privacy upon which a diverse society depends...

Our histories constrain what opportunities we notice and can take in life. The genes you have define the shape your body can grow into, in concert with environmental influences. But the cards you’re dealt don’t tell you how to play your hand; for that, you have to know which game you’re playing.  Natural selection acts through the relationships between an organism and ecology, a business and economy.  What works in one environment may fail in others...

For this special mini-series covering the COVID19 pandemic, we will bring you into conversation with the scientists studying the bigger picture of this crisis, so you can learn their cutting-edge approaches and what sense they make of our evolving global situation...

In several key respects, COVID-19 reveals how crucial timing is for human life. The lens of complex systems science helps us understand the central role of time in coordinating across scales, and how synchrony or misalignment leads to major consequences—whether it’s in how the metabolic differences between bats and humans can create an opportunity for interspecies epidemics, or in how the timing of society’s return to work could either help reboot or help destroy the world economy...

The coronavirus pandemic is in one sense a kind of prism: it reveals the many interlocking systems that, until disrupted, formed the mostly invisible backdrop of modern life, challenging the economy and our models of the world at the same time that it threatens individual and social health. The virus acts on, and invites new understanding through, the complexity we only take for granted at our peril...

“We should not have a strategy that involves killing a sizable percentage of the population. But, even if you were going to get over that ethical hurdle, [herd immunity for Covid-19] still isn't going to work...

Chances are, if you are listening to this around the time it was released, you’re listening alone. Right now the human species is conducting one of the most sweeping synchronized experiments of all time: physical isolation, restricted travel, shuttered businesses, our social lives moved online...
