- Why does cigarette smoke swirl in continuous lines rather than dispersing in air? Is it just the shape of air current or is there a binding force?
- Every computer program is compiled (or interpreted) by another program, called the compiler or interpreter. This includes compilers themselves. Is there a "common ancestor" compiler of all high-level programs today, and if so what is it?

| Posted: 25 Aug 2017 07:19 AM PDT In ideal conditions, when someone puffs out a smoke ring it travels while retaining its original shape - is there something holding the shape together or is it just particles travelling in their original direction without being dispersed by air current? Even when smoke leaves the cigarette and is transformed it appears to stretch out like gum, rather than disperse instantly: Is there a binding force or is it just the shape of air currents it travels through?

| Posted: 25 Aug 2017 07:15 AM PDT I assume the first compilers were written by hand in machine code. Then subsequent compilers can be written in the language implemented by that first compiler, etc. Is there a single hand-written program that basically "birthed" all high-level code we use today?

| Posted: 26 Aug 2017 06:54 AM PDT So, i just remembered a discussion I had with a friend and where I strongly disagreed with him and my maths teacher, because in my head, it makes no sense. So here is the scenario: There are three doors: Behind two doors is nothing, but behind one door is a car that you can win, you just need to choose the correct door. After you select one door, the Showmaster will open one of the doors with nothing behind them. Now you can choose if you want to stick with the door you first picked or if you want to switch. My math teacher said that you have a higher chance of winning if you switch doors, because when you picked the first door you picked a 1 out of 3 chance, but if you switch now it's a 50/50 chance For me this makes absolutely no sense, because as soon as one door is eliminated you essentially pick again, and both doors are a 50/50 chance. Or am I missing something? [link] [comments]  |

| Can we prove that there are things that have definite answers that can't be proven? Posted: 25 Aug 2017 12:21 PM PDT I've been interested in mathematical proofs, and I've been fascinated by the amount of things we are pretty sure we know the answer, but can't prove. I was wondering if we know if everything even has a proof. Are there mathematical concepts that, true or false, we will never find a proof for? [link] [comments]  |
| Posted: 26 Aug 2017 07:44 AM PDT Hello AskScience! We are members of the Society of Vertebrate Paleontology. We study fossil fish, mammals, amphibians, and reptiles — anything with a backbone! Our research includes how these organisms lived, how they were affected by environmental change like a changing climate, how they're related, and much more. You can learn more about SVP in this video or follow us on Twitter @SVP_vertpaleo. We're at our 77th Annual Meeting in Calgary, Alberta. Ask us your vertebrate paleontology questions! We'll be here to answer your questions later this afternoon (Mountain Time)! Joining us today are:

| Why does sour taste trigger your taste glands to release saliva ? Posted: 25 Aug 2017 05:24 PM PDT Why do your taste glands release saliva when you eat something sour but not when you eat something sweet or bitter? I've noticed this everytime I eat something sour but haven't seen it with any other type of flavor. Is it a specific gland that releases saliva ? [link] [comments]  |
| What kind of statistics are needed to determine whether a point is moving randomly? Posted: 25 Aug 2017 11:40 PM PDT Bear with me, there's some explaining to do here: I was watching water striders skim across the surface of a lake, and was wondering what kind of statistical techniques or math are needed to determine whether the movement is random, or following some sort of pattern. So a more precise formulation of the question: suppose we have a point S that starts at the origin. Every second, point S moves a fixed distance (let's say 1 unit) in some direction in the 2D plane. How long would I have to watch point S before I could be 95% confident whether or not the movement was random? Extension questions; suppose the distance moved is variable also, not just the direction. How does that change things? [link] [comments]  |

| How can some animals eat just one thing and get all nutritions and vitamins and all that? Posted: 25 Aug 2017 11:40 AM PDT We need to eat a balanced diet to get everything we need. Some our bodies can just create (classic vitamin D using our skin), but others we just have to consume. How can certain animals (how many are there? What is the percentage) just eat one thing. Like blue whales only eat krill. Does Krill just happen to contain everything they need? Or Pandas and eucalyptus leaves. I know cows occasional lick salt. Do those animals that we (mainly I ;) perceive to be single item eaters also snack on other items? But how does a blue whale, with very specialized eating habits, eat anything else? Side question: Does every animal need vitamin C? Scurvy must be horrible for an animal... [link] [comments]  |

| How do flat moles form in the first place? Posted: 25 Aug 2017 11:32 AM PDT Flat moles that look like a blotch of black or brown ink on the skin. Those that cannot be felt by hand. How do these moles form in the first place? Is there any way to prevent new moles from growing near other moles? [link] [comments]  |

| Posted: 25 Aug 2017 09:01 PM PDT I understand that you can't see magnetic field lines, but are the lines that are emanating from the top and bottom of the disk the result of the Sun's magnetic field interacting with charged particles? I'm assuming that charged particles in the corona are following the field lines while giving off heat. Since this is an infrared photo, I'm assuming that's why we see what appear to be field lines.

| Posted: 25 Aug 2017 05:37 PM PDT Apologies if the question doesn't seem clear. What structure can be formed by five distinct points (in 3 dimensions or higher) which don't all lie on the surface of a tetrahedron? [link] [comments]  |
