Cecelia invites her friend Konrad, who is back from his first semester at college, to share about what it is like to take a math class in college. Konrad goes over his math history and experience, and how the transition was from high school classes to college classes. In his honors calculus class, he is doing many proofs, so Konrad explains what the basic structure of a proof is. 

On this episode of Speaking Tangentially, Cectheplug and her special guest "Arccot Anna" explore the wonders of pi(e); the one with apples inside and the one with an infinite strand of digits after its decimal point. Tune in to hear the astounding record holder for reciting the decimal places of pi, what goes into squaring a circle, and folklore of how the great mathematician Archimedes figures out that the King's crown is not made of real gold. Beautiful Geometry by Eli Maor and Eugen Host is Cecelia's favorite book and is referenced in this episode. Highly recommend!

For the first episode of Speaking Tangentially, Cecelia teaches her friends about the proof of the irrationality of √2. Listen in to hear about how this proof works and how it con be represented through geometry!
