| Why is voltage and current specified in electrical equipments? Posted: 12 Apr 2018 04:41 AM PDT My phone charger, for example, has an output of 1.55A at 5V. My understanding is that Voltage causes current to flow. Current is the rate of flow. So in the case of my charger, does the voltage here matter? Why is it specified? To calculate power? What if I have another charger that's 1.55A at 10V? What does that mean? Surely, my phone isn't getting charged faster because they're both 1.55 coloumbs of charge per second. [link] [comments]  |

| How does mica rotate plane polarized light by 90 degrees? Posted: 11 Apr 2018 09:06 PM PDT I have a few pieces of iolite that allow me to demonstrate this property really effectively, but I don't have a good explanation for how the mica's crystal structure results in the rotation of light. I understand how a crystal's optical properties are determined by its symmetry and structure, and that mica is extremely anisotropic (hence its cleavage), and the pleochroism exhibited by iolite is intuitive enough to me, but the rotation caused by mica isn't quite clicking for me.

| What happens when you use Knuth's up-arrow notation with non-natural numbers? Posted: 11 Apr 2018 04:26 PM PDT Suppose you take Knuth's up-arrow notation. Using it on integers is easy: 3 ^ 3 = 33 = 27, 3 ^ ^ 3 = 333 , etc. But what happens if you place a fraction as the latter number? 3 ^ (1/3) is obviously the cubic root of 3, but what about 3 ^ ^ (1/3)? What if we place a negative number instead? Or a complex number? [link] [comments]  |
| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 11 Apr 2018 08:14 AM PDT 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]  |
| How do Electromagnets Work with Conservation of Momentum? Posted: 11 Apr 2018 07:06 PM PDT I'm a grad-level physics major, but a couple of days ago I got asked a question that I still haven't been able to satisfy myself that I fully understand. Suppose you have two solenoids, A and B, separated by some distance. I connect B, so that it is pushed outwards by A's field, and then immediately disconnect A so that it has no dipole moment. Because the field from B takes time to propagate, coil A will have zero dipole moment by the time the field "arrives", and so no reaction force will be generated. One object has been pushed, while the other has not, seemingly generating thrust from nowhere. Time-varying fields aren't my strongest point, so I strongly suspect that what I'm missing is somehwere in the turning of the coils "on" and "off", i.e. that the changing fields in this window generates a non-zero Poynting vector, but this doesn't seem to grok with the symmetry of the problem.

| What reasons necessitate the imidazole ring in the base pairing of RNA/DNA? Posted: 11 Apr 2018 04:38 PM PDT Specifying: This is not asking 'why is there an imidazole ring in a purine'. Rephrasing: What reasons prevent the phosphate backbone DNA/RNA from using ONLY pyrimidines in their base pairs? Here are some things I could speculate possibly being the case: Is there not enough variety in naturally occurring pyrimidines to support enough base pairs? Is it because the hydrogen bonds between pyrimidines for whatever reason are either stronger or weaker than ideal for the various processes that depend on hydrogen bonds? Is it that a pyrimidine base pair would, because of being of shorter length, end up twisting the backbone more than it wants to be twisted, and/or stacking too much closer to the other base pairs? (for processes that depend on the power necessary to untwist the helix, and overcome the stacking energy) Is it that this configuration would not support the major and minor groove that becomes necessary in other processes? I know I have yet to read further in depth, specifically, on the topics of pi stacking and the ultimate function or necessity of the major and minor grove. Thank you [link] [comments]  |
| CRISPR Cas9 - How does the Cell decide which repair pathway to proceed with? Posted: 11 Apr 2018 03:02 PM PDT I understand that Cas9 is an endonuclease that makes a nick in the DNA, but then how does the cell decide whether to proceed by non-homologous end-joining or homologous recombination?

| Can strong wind influence the path (or the speed) of sound and light? Posted: 11 Apr 2018 02:52 PM PDT not sure if its a legit question or just dumb. but speed and sound travel through matter at a certain speed (i think). if that matter happens to be air, and if that air happens to be a strong wind, would this mean that it does get influenced?
