1. Participants at a meeting drank while looking at mathematical formulas and discussing their memories and understandings of the formulas. They talked about limits, Euler's identity, quadratic equations, logistic maps, and other formulas. 2. They tried deriving Euler's formula but were unsuccessful. They looked up facts about i^i on Wikipedia while drinking. 3. They discussed Riemann zeta function, Fibonacci numbers, Laplace transforms, Fourier transforms, perfect numbers, and recommended sci-fi books. They enjoyed reminiscing and gaining new insights about mathematics through their conversations.
