Met a friend I haven't seen in a while. As good grad students, we chatted about research. I talked about my quantum physics simulations and he talked about MOS cap parameter extraction and modeling...
And then I managed to turn a conversation about the new football-themed decor at a campus dining place into a dialogue about philosophy, religion, and science :-P
"So many football pictures here... people are obsessed!"
"Yeah, the whole sports fan concept is like a religion... hardcore fans almost worship their favorite teams and/or players..."
"Are you Christian?"
"Buddhism is more like a philosophy... Christianity is more similar to sports team worshipping :-P"
"So do you believe in anything?"
"This may sound a little strange... I believe in the laws of Nature."
"Like Newton's Laws and such?"
"Yes, although they're only a subset of Nature's laws because they only work part of the time... And we won't ever discover all the laws because of our limited perception..."
(Then we talked about scientific discoveries and technological advancement... and decided that anything could happen in the next thousand years.)
