Mike's face says it all—thermodynamics isn't just a subject, it's an existential crisis . That equation (dQ = dU + p·dV) is the First Law of Thermodynamics, essentially saying energy can't be created or destroyed, just transferred while making everyone's life complicated. The smoke around him perfectly symbolizes the mental fog that descends when trying to balance energy equations at 2AM before finals. Energy is conserved, but your sanity? Absolutely not. The face of someone who just realized the universe is just one giant heat transfer problem that ends in maximum entropy.
