  • I actually think your hypothetical smoker is a great example of the opposite. Someone who lived it, understands the struggle, and ultimately regrets their choices is exactly who you want to hear from. It’s why the really cheesy don’t smoke PSAs don’t ring a chord with most people, they don’t feel genuine.

    I don’t think Thoreau is some enormous hypocrite, but I do absolutely understand why some people might feel bitter about it when they learn the greater context.









  • Heat doesn’t really exist at an individual particle level, it only describes the average kinetic energy of a large number of particles. “Normal” evaporation occurs because all the water molecules are jiggling around fast enough that sometimes some get knocked off at the top and fly away. The theory from this paper says that light can strike a single water molecule just right that it breaks off without help from the others.

    Saying this is “without heat” means that the light isn’t simply increasing the average kinetic energy at the top of the water and speeding up the rate of “normal” evaporation. They think it’s specifically acting on a single molecule at a time.
