| Why do fluorescent tubes contain mercury vapour? Posted: 04 May 2017 02:50 AM PDT I understand the the mercury electrons become excited, move up and energy level and then release a UV photon which then passes on energy to the electrons of a phosphorus coating, but why can't the electrons from the voltage supply pass on their charge directly to the electrons of a phosphorus atom inside the tube which would then emit the visible light photons, removing the need for the mercury vapour?

| Posted: 03 May 2017 04:54 PM PDT Here is a simulation of the rotation of Pluto's moon Nix. According to wikipedia, it's rotation can only be predicted 30 days into the future before it becomes too chaotic. What causes this chaotic rotation? [link] [comments]  |

| Does string theory make predictions that can be measured in experiments? Posted: 03 May 2017 11:40 PM PDT I heard several talks about string theory, but usually they are very technical and no one was able to give me some examples of predictions made by string theory that can be investigated in experiments, for example, at the LHC.

| Do objects less than 5730 years old have accurate dating measurements? Posted: 03 May 2017 07:33 PM PDT Okay so this may be a dumb question, but need an answer quick and didn't have the time to do enough research myself to answer it. So I'm having some debates with my parents (hardcore Creationists, I'm undecided at this point lol) one of my arguments for the errors in the creation story is the fact that dating techniques are pretty accurate and are no where near the claims of 7000 years like they like to say. I came across this one question though; if dating techniques are only accurate for greater than the half life of the element used, and carbon-14 has the smallest half life of 5730 years, is it hypothetically possible that all materials ever tested are less that 5730 years old (sort of close to a creationists timeline), and therefore all measurements can be listed as inaccurate? I may be completely out to lunch here and I apologize if I am. I'm not looking for other reasons as to why old-earth is a lot more plausible (there are enough that I am aware of already). Thanks for your time. [link] [comments]  |
| Is it possible for nuclear fuel to accidentally reach criticality? Posted: 03 May 2017 05:21 PM PDT I'm gathering information for a story I'm writing and I want all aspects of the story to be as plausible as possible. So as the question states, whether in travel or handling accidents, if fuel rods were majorly damaged in any way and the pellets somehow spilled into a massive pile could it possibly go critical? Or is there a reactor fuel source other than PWR fuel rods that would be contained in a way that makes them more likely to go critical? Thank you for any assistance you can lend in the matter.

| Posted: 03 May 2017 12:53 PM PDT My understanding is that most of a metal "allergies" are caused by irritation due to the metal's oxide. Even though these metals are considered to be relatively unreactive, they can still be oxidized. If this is the case, why are they less likely to cause problems? [link] [comments]  |
| When a full tooth is knocked out, then later reinserted, how does it re-bond with the gums? Posted: 03 May 2017 02:13 PM PDT Basketball player Isaiah Thomas had his tooth knocked out then had a dentist procedure the next day to reinsert it. Do dentists just stick it back in and the gums clamp back down on it? Or do they use a biodegradable glue, or a mechanical fixture? [link] [comments]  |
