  • It’s not to do with breaking thermodynamics. The grains of salt simply act like little so-called “nucleation points” where the bubbles can form easier. That’s why you’ll often see the water suddenly boiling and bubbling violently just as you add salt.

    The water was “superheated” above the boiling point, but didn’t have imperfections in the pot which allowed the bubbles to form easily.












  • I had an Nokia, my last “featurephone” before I got my first smartphone, which actually had an FM tuner built-in. It used the headphone wire as an antenna as far as I recall. Quite neat, not that I ever really used it, but it was perfectly serviceable. And a great way of having music on the go in the days before streaming music was widely available.



  • I suppose “offering” might not be the right word, but I think the whole point is whether it is a waste of taxpayer money or not. As I wrote, I don’t think it makes sense to expect a worthwhile economic return from hosting the Olympics, but there is of course other types of “wealth” besides money. For example, if only money mattered a building should be built in as cheap a fashion as possible, but spending a bit more on making it beautiful is worth (to me at least) for the “wealth” it provides society in improving the beauty of our surroundings. I think the question becomes if it is worth the cost of hosting the Olympics, for the “wealth” of allowing the citizens of a country/city a chance of attending without travelling half way around the globe. Additionally there’s the “wealth” gained from the civic pride of having your country/city be the center of the world’s attention in a largely positive manner for the course of the games.
