                    P versus NP and the Limits of Computation 
                      
                   
                    The 
                      security of encrypted computer protocols such as credit 
                      card transactions depends on unproven mathematical assumptions 
                      concerning the limits of computation. The central assumption 
                      is the conjecture known as P vs NP, which is 
                      one of the million dollar questions listed by 
                      the Clay Mathematics Institute. I will explain the conjecture, 
                      and how our world could be very different if it turns out 
                      to be false.

                     Why Algorithms Are Poised to Become the Language of 
                    the Living World  
                    (Video of the talk) 
                    Just as physics speaks the language of mathematics, the new 
                    sciences of the 21st century speak the language of algorithms. 
                    The difference lies in the high descriptive complexity of 
                    the systems commonly found in social and biological organisms. 
                    While history plays virtually no role in physics, it is the 
                    distinguishing feature of the living world. Algorithms provide 
                    not only the expressivity needed to model complex living systems 
                    but also the analytical tools for their analyses. This (self-contained) 
                    talk will illustrate the power of "natural algorithms" 
                    by examining broad families of agent-based systems for which 
                    algorithmic tools can do what differential equations cannot.
