QED: If I make myself a nice hot cup of coffee, inevitably get called to something ‘more important’ and I’m away for an extended period of time, my cup of coffee is no longer hot. I would expect that, as part of the universes ongoing quest for equilibrium, my coffee would be room temperature, but actually it always _feels_ somewhat colder.
Is this a trick of the mind or is it actually colder somehow?
In: Physics
1. You expect it to be hotter than it really is, so the perception is that it’s colder than you expected.
2. Your body heat is hotter than room temperature. It feels cold-ish to you because, to you, it is.
