| Why do the names of most elements end in "ium"? Posted: 29 Mar 2018 05:11 PM PDT Was looking at a periodic table recently and noticed most end in "ium." I knew a lot did, but I didn't realise just how many. [link] [comments]  |

| What would happen if we split a proton or electron? Posted: 29 Mar 2018 02:59 PM PDT Would it give off energy like when you split an atom? [link] [comments]  |
| How do our eyes get tricked into seeing a mirage? Posted: 30 Mar 2018 03:05 AM PDT I'd like to know the physics behind mirages, but also if they are partly due to some limitations in our vision. If so, are there any animals who evolved their sight to distinguish a mirage from a real lake? [link] [comments]  |
| What is the purpose of cutting flower stems at an angle before putting them in a vase? Posted: 29 Mar 2018 07:16 PM PDT It seems like I was told this when I was a kid, and I still continue to do it. Is it just an aesthetic thing or does it have a point? [link] [comments]  |
| What determines if an organ is a new, prior-to unknown one, or part of an existing one? Posted: 30 Mar 2018 03:24 AM PDT The recent news of the new 'discovery' of the interstitium got me wondering: why is it being called a 'new organ'? Why is it not simply a part of the lymphatic system, since it seems to contain lymph anyway? More generally, what are the criteria for something being an 'organ' rather than just 'part of an organ'? More specifically, why is the interstitium a new organ and yet the brain's newly discovered sewage system is part of the lymphatic system? [link] [comments]  |
| Posted: 30 Mar 2018 07:02 AM PDT I think I'm getting lost around the part where he says that Y can not be higher than X and goes into proving so by making Y higher than X. Or maybe I'm not understanding further back. [link] [comments]  |

| Does the habitable zone around a star get larger as the star's size increases? Posted: 29 Mar 2018 02:16 PM PDT e.g. our suns habitable zone starts at 0.95 a.u. and ends at 1.37 a.u. giving a range of 0.42 a.u. Question being do larger stars have a larger range? [link] [comments]  |
| When you die does it take time for all your cells to die too? Do any cells survive after our death? Posted: 29 Mar 2018 01:35 PM PDT Also what happens to other organisms we carry like gut bacterias? [link] [comments]  |

| For a national grid, how soon after electricity is generated is it consumed? Posted: 29 Mar 2018 11:40 AM PDT Is there much storage in a national grid or is it produced almost on demand over vast areas? [link] [comments]  |
| Posted: 29 Mar 2018 01:28 PM PDT To provide some further insight, a photon is emitted from a star, and this star has gravity. The light from the photon is moving fast enough to escape the gravity. But if this photon comes close to a black hole, it can be warped and bent around it, or captured into it by crossing the event horizon. So we know that gravity can effect light; then would not gravity from the things behind the photon (that is, things from the point where the photon was emitted) have some kind of pull on the photon, slowing it down? I guess another way to state this is, if the event horizon of a black hole can alter the course/speed of a photon, why can't galaxies and stars 'pull' on photons and cause their speed to slow down over huge distances?

| How do computers handle numbers larger than what it can compute? Posted: 29 Mar 2018 01:57 PM PDT For example, my pc is 64 bits, but I can so operations larger than 250,000. So if it can only compute 64 bit numbers, how can it do operations on numbers much larger the 64 bit integer limit. [link] [comments]  |
| What decides where a malignant tumor is most likely to metastasize? Posted: 29 Mar 2018 01:09 PM PDT Why do some thyroid tumors very rarely metastasize via lymph vessels and prefer hematogenic spreading, for example? [link] [comments]  |
| Is there a way to estimate thermal properties of theoretical alloys? Posted: 29 Mar 2018 05:33 PM PDT I am currently working on a project that involves many metals melting and reforming into a solid. It made me wonder if there would be a way to estimate the new thermal properties such as conductivity of the new material. I originally tried a simple weighted average of the conductivities, but when comparing that known alloys it is an extremely poor estimation. I have found a lot of papers that propose methods for finding conductivities of alloys made up of two metals, but I am working with potentially much more. I was wondering if there was a way to estimate the conductivity of the new alloy or at least put bounds on it. Sorry if this is a simple question i have almost no experience with material science.
