Brown Bag Seminar
Who:Mr. Karl Castleton. Guest lecturer from Pacific Northwest National Laboratory
What:Ubiquitous Recursion
When:Friday January 30
Where:Wubben 199 at 12:00
Ubiquitous

Mr. Castleton will discuss the prevalence of recursion in fields varying from music, art, to mathematics and computer software. The most common recursive definition shown to students is the Fibonacci Sequence. 1 1 2 3 5 8 ... The definition of this sequence is:

f(n)=f(n-1)+f(n-2) where f(0)=f(1)=1 and n>1
What Mr. Castleton will demonstrate is that something being defined by itself (plus more) is far more prevalent than just some interesting series in mathematics. Take for instance the "word" RECURSION above. If you were going to describe it to someone over a telephone how would you do it? Do you use the word "RECURSION" in the definition? Where else are you tempted to do that as well?
