If you can combine Water with Cesium/Rubidium to make a functional exothermic clock... you would rate a certifiable award in some category. Extra classification points if you can contain it in an hour glass. I'm sure all would agree the resulting display would be quite spectacular if not an

Time nuts, Being a recent addition to the list, I'm going to use my one dumb question* card on an epistemological question that's puzzling me. When you come up with a better measuring device (clock, oscillator, etc.), how do you know its better? Since, presumably, the only other tools

Mark, Good question. Here are the rules: 1) If all you have is one clock - then that is the true time, period. 2) If you have two clocks and they always agree, then that just means you need better measuring tools. 3) If you have two clocks and a good comparator, then at least you can tell how
