Mathematician Satyan Devadoss offers a Veritas Forum talk titled "God, Math, and the Multiverse" (video embedded below). I believe the talk is primarily aimed at non-Christian Caltech students.
On the one hand, I don't agree with everything he says. Plus, most of what's said only touches superficially on the subjects in the title. Although I'm fairly certain this is intentional; he probably only meant to offer a taste of Christianity to whet the appetite of the audience. On a lesser note, I'm of the opinion that questions in a Q&A session should be read by a moderator, not asked directly by the questioner since the potential for abuse is higher in the latter (among other issues).
Nevertheless, I appreciate the fresh perspective Devadoss brings to Christian apologetics. He shines new light on points many of us have probably heard before. His admiration for both the arts and math and sciences resonated with me as well since I'm likewise someone who has always had an affection and respect for "the two cultures." Not to mention he's an amiable and amusing speaker. I think he did a pretty good job in the Q&A session too.
And I appreciate the Christian students making the most of the event to invite people to explore Christianity further (e.g. gift certificates, free dinners, conversations).
