  • 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.














  • On top of the many other reasons here, there’s also a pretty distinct difference between countries without a US extradition treaty and countries that won’t extradite to the US. Many countries without formal treaties will still happily hand over a US citizen trying to hide in their country. It might be a different story if he had dual citizenship somewhere but anywhere he tried to flee he’d be immigrating illegally.



  • 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.
