| Posted: 25 Oct 2017 06:50 AM PDT I know the microwave I had 20 years ago and the one I have now are about the same, because I have always punched 3 minutes while making popcorn, and stop it somewhere after 1:00 is left. If there are still advancements, what new things are coming out that I'm missing? What could we do to improve the technology of reheating foods? [link] [comments]  |
| Posted: 24 Oct 2017 07:50 PM PDT It seems that a higher kinetic energy to the first domino would lead to less time to fall over, with the next domino having more velocity, etc. On the other hand, every other wave I'm familiar with has a characteristic speed. [link] [comments]  |
| Why aren't we using thorium as a primary source of energy? Posted: 24 Oct 2017 11:50 PM PDT I recently watched a mini documentary on thorium and from what I understand it:
So why isn't it being utilized to it's full potential? [link] [comments]  |

| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 25 Oct 2017 08:06 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]  |

| Is there a frame of refference from which electromagnetic waves appear only as electric waves? Posted: 24 Oct 2017 11:37 PM PDT A stationary charge has an electric field surrounding it. A charge, moving with a constant velocity, has a magnetic field, however this can be explained to only be a product of special relativity, because from a frame of refference, moving with the same velocity as the charge, it appears stationary and thus only produces an electric field. Is there a frame of refference, from point of which harmonically oscillating electric and magnetic fields(electromagnetic waves) appears only as an electric field? [link] [comments]  |
| How does the F-35 air intake design overcome the problem of boundary layer ingestion? Posted: 24 Oct 2017 07:44 PM PDT https://media.defense.gov/2014/Mar/11/2000783826/-1/-1/0/140310-F-NG006-007.JPG Most planes have air intakes that aren't flush to the fuselage to avoid undue stress on the turbine blades in the form of uneven boundary layers that have formed on the body and the other edge of the inlet. Seeing as the F-35 can fly properly, how do the engines cope with the consequences of flush mounted inlets? Boundary layer suction? Some other super classified technology? [link] [comments]  |

| Why are stars different sizes? Posted: 24 Oct 2017 06:51 PM PDT If stars form when clouds of mostly hydrogen gas start to fall into a ball due to gravity. If there is enough gas, eventually that gas becomes so compressed that the hydrogen atoms start to fuse together to form helium atoms and the energy released from that fusion ignites the star. My question is that there has to be a critical mass at which hydrogen atoms start to fuse. That shouldn't deviate. So once critical mass is reached, wouldn't the ignition of the star blow away any additional gas and thus limiting the size of stars? Obviously we stars of all sizes, so what am I missing? Maybe stars made of heavier gases? [link] [comments]  |

| What makes bismuth crystallize rather than just solidify smooth? Posted: 24 Oct 2017 11:07 PM PDT I've watched every bismuth DIY tutorial, and I'm just not grasping how to make crystals form on the BOTTOM of the pool of solidifying liquid. I wouldn't even believe it's possible except that people on YT have plainly done it. I've tried every combination of factors from cooling it extremely slowly to pouring it into room temperature mold, but the bottom surface always solidifies instead of crystallizing. (In fact, I'm not sure it isn't crystallizing first and then promptly being solidified over.) I'm very chemistry ignorant, so it's possible I'm overlooking something very obvious. I've been able to form crystals in a pot from the top surface down, but not in molds (Like a geode or egg) from the bottom up. Is there some glaring error I'm committing? Any help is super appreciated, I'm nearly losing sleep over this. [link] [comments]  |

| Does the body physically acclimatize itself during the colder months? Posted: 24 Oct 2017 03:06 PM PDT We all know that 50°f at the end of winter than at the beginning. I presume we acclimate after so much time, but is any of this happening on a cellular level? Do the cells in our skin change at all over time to help handle the cold better? [link] [comments]  |
| [Genetics] How does stranded RNA seq with dUTP work? Posted: 25 Oct 2017 04:17 AM PDT I understand the method up to second strand synthesis using uracil, followed by uracil degradation. At this point, you have a single DNA strand complementary to the original RNA. But if you amplify it by PCR you have a double stranded PCR product, so how do you tell which was the original?
