| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 10 Nov 2021 07:00 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary 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]  |
| How to break strong ethanol & oil emulsions? Posted: 10 Nov 2021 05:34 AM PST Hello, I have been struggling to break essential oil-alcohol emulsions. I tried many experiments but nothing came out of them Fraction distillations, adding water or salt or both, supersaturated solutions, non polar solvents, heating, cooling but all I'd get would be a turbidity or emulsion or louche that doesn't break. Some concrete examples are the following: Pastis, raki, ouzo effect, absinthe. If you dilute the following liquors with water they form an emulsion in the form a white turbid solution (ouzo effect) Any idea? Thank you for your time! P. S: I had some ideas in mind like centrifuging, but I am not planning to pay a few 100 bucks to make a couple of experiments.. [link] [comments]  |
| Why are there atmospheric tides at 12 hours? Posted: 09 Nov 2021 10:37 AM PST I've read around this a little and got answered such as 'it forms a square wave rich in harmonics...' to ' resonance theory and free oscillation in the atmosphere', but as far as I can understand, it's due to the rate of heating and cooling being uneven. Can someone help with a simple ish answer? Thanks in advance! Edit: the title should say with a frequency of 12 hours. [link] [comments]  |
| [Semiconductors] How does the diffusion of dopants create features? Posted: 09 Nov 2021 04:22 PM PST Say I have an integrated circuit with 100 NPN transistors on it. How are such features actually created? Like, I'm imagining an NPN transistor as an area of the chip where you've got a bit of phosphorus at the collector/emitter and some boron at the base. But, how do you get these dopants where they're supposed to go? [link] [comments]  |

| Are twins/triplets/etc more likely to reproduce more twins/triplets/etc? Posted: 08 Nov 2021 02:19 PM PST I'm a failed triplet(one of my siblings was absorbed and the other was miscarried) my dad is a twin and his mother is too. Is it more likely for twins to reproduce more twins than non twins? [link] [comments]  |
