I think a way to answer Bruce Sampsell's question might be to run a simulation with the choice being made after the host has opened the door, and show that that agrees with his prediction. Thus you show why his intuition is correct, and also why his intuition is wrong (depending on whether one's first choice is made before or after the host opens the door). I find it necessary to satisfy my intuition - if I can't show why it is wrong, how do I my "right" answer is right?

Happy Birthday to Alvin! August 2014 marks the 50th anniversary of Alvin, the submersible that has been so influential in ocean research, including the discovery of hydrothermal vents. In 2014, a retrofitted Alvin also took its first test cruise.
Heather Olins, a doctoral candidate at Harvard, studies microbial ecology at deep sea hydrothermal vents with the help of Alvin, and shares her personal tribute to the submersible on these landmark occasions.
