Saturday Physics for Everyone

Add to Calendar 12/1/2018 10:15 am 12/1/2018 America/Chicago Saturday Physics for Everyone DESCRIPTION:

When engineers build machines, they must make decisions about performance.  For example, designing an internal combustion engine involves choosing between efficiency (a Prius) and power (a Porsche).  Engineers can’t have it all!  Amazingly, biological evolution involves the same type of constraints—often called “trade-offs.”  I will talk about how we tried to evolve bacteria to grow fast and swim fast in my lab.  Surprisingly, bacteria cannot do both and must, like an engineer, choose between fast growth and fast swimming.  I will discuss when and why bacteria choose a Porsche over a Prius, or a Prius over a Porsche.
