| Does every pure chemical have a triple point? Posted: 09 Jan 2016 02:51 PM PST A triple point is a temperature and pressure where the substance is simultaneously a solid, liquid and a gas Are triple points for some substances predicted theoretically but hard to test? [link] [193 comments]  |

| Why do small objects stick to our fingers when we push down on them? Posted: 09 Jan 2016 11:16 PM PST There was a staple on the ground, so pushed down on it with my finger, and it stuck to my finger for a short time (not puncture). Why does this happen? [link] [11 comments]  |
| Why can't we create other beneficial molecules from the sun, like we do with Vitamin D? Posted: 09 Jan 2016 01:52 PM PST Many organisms can photosynthesize and we need sun exposure for vitamin D. Why can't we then harness the sun for ourselves to synthesize other molecules or even just harness the energy of the sun in a manner analogous to photosynthesis? Thanks! [link] [20 comments]  |

| Effect of genes working with other genes? Posted: 09 Jan 2016 11:01 AM PST What amount of the formation of organisms is directly from the coding of DNA vs something only happening when the gene is expressed in an organism? Ex: If we copy genes from one animal to another could we unknowingly change the outcome of the gene because gene X only looks like X if it is used with gene Y. Could we use RNA to tell us if gene Y and gene X are being used or would X gene only be shown as active because it is the only one being produced. [link] [12 comments]  |
| When space expands, do objects get bigger? Posted: 09 Jan 2016 08:03 AM PST It seems to me that in an expanding universe, objects would enlarge in tandem with space and so the apparent distance between 2 objects should stay the same over time barring any other movement. Obviously, this can't be the case, otherwise we wouldn't be able to notice the expansion in the first place, but do objects change in size at all? How does the expansion of space affect the size and internal structure of objects? [link] [39 comments]  |
| Why does my body have the same freckles/birthmarks throughout my whole life? Posted: 09 Jan 2016 10:17 PM PST My skin cells regenerate, though I'm not sure at what pace. So why don't freckles and birthmarks disappear with time? [link] [5 comments]  |

| Is it possible to catch 2 different cold viruses at the same time? Posted: 09 Jan 2016 11:24 AM PST If cold viruses are constantly mutating and always changing, doesn't that mean you can catch a common cold from one person and then catch another version of the common cold from somebody else? If I get over a cold (and so my body is well-equipped to fight that particular virus), am I safe to be around other people with the common cold, or could I catch it again just as easily?

| Can sign language have an accent? Posted: 10 Jan 2016 03:02 AM PST Additionally, does sign language changed based on the country of origin? [link] [comment]  |
| Posted: 10 Jan 2016 01:32 AM PST Here is an example of a demagnetisation curve. Let's assume we start somewhere in positive H-direction (e.g. 100 A/m) and slowly decrease the external field (strength). If we would turn it off (H=0), we would still have a flux density B of B_R (remanence). If we decrease H further (H now < 0) and turn it off, B would still be B_R. What happens if we decreased H to "-H_Saturation" < H < H_C and we turn it of? Would it still go back to B_R? At what point will it fall to -B_R? Does the material have to be saturated in negative direction? Thanks for your help. [link] [comment]  |
| How (where, when) exactly does limescale deposit in electric water kettles during boiling process? Posted: 09 Jan 2016 05:22 AM PST As I understand, there is an equilibrium in the water: Ca2+ + 2HCO3- ⇋ Ca2+ + CO32− + CO2 + H2O where balance moves right as CO2 leaves the boiling water. Does it happen everywhere in the water? How quickly does the CaCO3 fall to the bottom? Why is there limescale on the walls (why doen't it fall to the bottom of the kettle)? (context: I want to make a tea boiler+infuser, where i could thown away any limescale each time alongside with the used tea leaves.) [link] [5 comments]  |
| Quantum fluctuations after big bang? Posted: 09 Jan 2016 06:25 AM PST I was just wondering what the actual mechanism of these "quantum fluctuations" that ive read about are. As i am understood they are some how responsible for fluctuations in particle density in the very early universe which caused stars, galaxies etc. to form, and i was just curious what they actually are. Thank you. [link] [8 comments]  |
| Why do eggs take longer to boil at higher altitudes? Posted: 09 Jan 2016 12:46 PM PST I get that it takes longer for water to boil at higher altitudes. And I get that the boiling point of water changes, and I get why. What I don't get is this: If you're applying the same amount of heat (energy) into the system, doesn't the egg get cooked ("boiled") at the same time anyways? does boiling water really transfer heat that much more efficiently? Thanks. [link] [8 comments]  |
