Google has various talks setup by employees or corporate that bring speakers in every sector and across the spectrum. Here's Mayor Bloomberg's talk:
New York City Mayor Michael Bloomberg visits Google's Mountain View, CA, headquarters for a conversation with Google VP Sheryl Sandberg. This event took place on June 18, 2007, as part of the Authors@Google series.
Tim Keller visits Google's Mountain View, CA, headquarters to discuss his book, "The Reason for God." This event took place on March 5, 2008, as part of the Authors@Google series. (Disclosure: I attended Keller's church when I lived in NYC, and he's my favorite preacher.)
Why is there suffering in the world? How could a loving God send people to Hell? Why isn't Christianity more inclusive? Shouldn't the Christian God be a god of love? How can one religion be "right" and the rest "wrong"? Why have so many wars been fought in the name of God? These are just a few of the questions even ardent believers wrestle with today. In this book, Tim Keller uses literature, philosophy, real-life conversations and reasoning, and even pop culture to explain how faith in a Christian God is a soundly rational belief, held by thoughtful people of intellectual integrity with a deep compassion for those who truly want to know the truth.
As the founding pastor of Redeemer Presbyterian Church in New York City, Tim Keller started his congregation with a few dozen people. It now draws over five thousand weekly attendees who meet in three Manhattan locations. Redeemer has since spawned a movement of churches across America and throughout major world cities.
