| Are people with photographic memories less prone to developing false memories? Posted: 18 Dec 2018 07:38 PM PST For example, memories getting revised in the act of recall, or memories being tampered with through bad interrogation techniques. Also, are they less prone to dissociating from certain memories, like the memory of a very traumatic event? [link] [comments]  |
| Posted: 18 Dec 2018 06:40 PM PST I have ASD and I've always wondered this. I was thinking that in a similar way to the proposed model of Aberrant Salience for psychosis (which says that psychotic symptoms first emerge when excess dopamine leads to the attribution of significance to stimuli that would normally be considered irrelevant), a similar thing happens in ASD. Am I on the right track or am I completely off? [link] [comments]  |
| Do any of the stars in the centre of our galaxy harbour planets? Posted: 19 Dec 2018 04:57 AM PST I'm also curious as to whether there are a ton of star/planet collisions in the centre.. I'm assuming there would be massive, massive explosions of stars constantly blowing themselves up. [link] [comments]  |

| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 19 Dec 2018 07:11 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Engineering, Mathematics, Computer Science Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |

| Is gravitational bending of light wavelength-dependent? Posted: 19 Dec 2018 12:18 AM PST Obviously it is dependent on the mass of the object bending the straight path of light. But does the bending depend on the wavelength of the light? (Ie. is there something like chromatic aberration in optical lenses when looking at gravitational lensing?). Also, does gravitational lensing itself cause an additional redshift effect? (Which I would expext as the proper length of the path of light is lengthened/stretched). (I wasn't quite sure whether this eas better flaired Physics or Astronomy; mods having experience, please feel free to reassign). Thanks for your insightful answers! [link] [comments]  |
| What is the influence of pressure on the speed of sound ? Posted: 19 Dec 2018 02:57 AM PST I am currently working on the automatisation of a silver iodide generator.I have to check an acetone level in a pressurised container, usually between 4 and 10 bars. So I will use ultrasound to get an approximate value of the distance between the top of the container and the surface of the liquid. I was wondering if I there was a link between the speed of sound and the pression inside of the container or if it close to 340m/s. [link] [comments]  |
| Is it more efficient to let a building cool down while absent? Posted: 19 Dec 2018 06:55 AM PST We recently had a longer discussion about energy-efficient heating. If you are leaving your house for an hour, an afternoon, a week-end or a week, is it more energy-efficient to (A) turn all the heating down or off, and to re-heat the building when you come back, or to (B) keep the heating at a constant level? The argument for (A) was that overall, the heating has to replace the energy lost by the house to the environment. When the house cools down, it overall loses less energy since the temperature gradient to the environment will be smaller (law of thermal conduction), so the amount of energy to replace when you turn the heat back up will be less than if the heating was constant. The argument for (B) was that the (inner) walls of the building would start to cool down, and that they need significantly more energy to be re-heated. Or does it depend on some additional factors, like the time span, the heat different, the building properties etc.? There are of course more practical issues like pipes freezing, mold building up etc. that are out of scope for this question. [link] [comments]  |
| How does radiometric dating work? Posted: 18 Dec 2018 07:39 PM PST I think I understand the basic concept of radiometric dating by counting the ratio of parent to daughter elements, but in order to date something from long ago it seems like you would need to have at least 7 pieces of information:
It seems like we're able to find #7 and a small fraction of #6 through modern instruments and reviewing data records, but I can't conceive of how the other data points could possibly be measured. Is there a way to measure 1-6 that I'm just unaware of, or is the accepted practice that of assuming data points with some sort of justification that doesn't rely on direct empirical data?

| Is there a formula to find out at which distance (me-points) two points look like one? Posted: 18 Dec 2018 11:10 PM PST Hey, I have a question about the resolving power. At which distance (from the points) do two 5cm points, with 5cm in between them, look like one? Is there some kind of formula to find out from any distance (me-points), that I could use like a cross multiplication? If there were two points on the moon, it would look like one seen from Earth. But at what dimensions/distance etc..? Thanks [link] [comments]  |
| Is there any voltage potential difference between the Earth and the Moon? Posted: 19 Dec 2018 01:13 AM PST If we could have a giant, purely ideal, voltmeter, and put one probe in Earth's soil and the other in the Moon's soil, what would it measure? [link] [comments]  |

| How hot is the accretion disk of a black hole? Posted: 18 Dec 2018 03:51 PM PST Doing some science fiction stuff, need an accurate gauge of how hot the accretion disk of a black hole is. Google search yielded no results. Thanks! [link] [comments]  |
| Why does the shingles vaccine work? Posted: 18 Dec 2018 10:14 AM PST My understanding of the way vaccines work is that it gives your body a chance to create antibodies so when it comes in contact with the actual virus it knows how to fight it. So, why is it that you can get shingles more than once but a vaccine exists? Wouldn't having the virus originally give you the antibodies that you would get from the vaccine? [link] [comments]  |
| Is it possible for two planets to orbit so closely to one another that their atmospheres intersect? Posted: 18 Dec 2018 04:56 PM PST Is it possible for two planets to orbit so closely to one another that their atmospheres intersect? Has such a scenario been observed? Is it theoretically possible for this to occur without the two planets destroying one another? [link] [comments]  |
| Why is specific heat capacity of saltwater lower than that of pure water? Posted: 18 Dec 2018 08:37 PM PST Why is specific heat capacity of saltwater lower than that of pure water? Does the explanation has anything to do with intermolecular forces? Thank you in advance! [link] [comments]  |
| Why is it justified to use just even one "free" parameter in theories in the physical sciences? Posted: 18 Dec 2018 06:09 PM PST Why is it okay to tune a free parameter (or maybe a few free parameters) in order to get the results you are aiming for? [link] [comments]  |
