| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 16 Jan 2019 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]  |
| Posted: 16 Jan 2019 06:35 AM PST For example, angular momentum for the Earth-Sun system is L = r*m*v (assuming Sun's centre as reference). Universe's expansion will cause r to change year over year. So how does angular momentum L remain conserved? [link] [comments]  |

| How do we know what electron shells look like? Posted: 16 Jan 2019 06:06 AM PST I was in my introductory chemistry class today, learning about orbitals and subshells, and we looked at the shapes of different subshells. Ive learned about experiments that taught us about how we know what an atom looks like but ive never heard of how we know what orbitals look like. [link] [comments]  |

| How is, say, lung cancer from smoking contracted? Posted: 16 Jan 2019 07:47 AM PST Is it through continuous exposure of harmful chemicals to the body or is it some kind of 'virus' per se that we can suddenly contract by sheer luck of having smoked a single cigarette? [link] [comments]  |
| Why does an object projected above escape velocity follow a hyperbolic path? Posted: 16 Jan 2019 07:22 AM PST So I just learnt this in school and our teacher didn't explain too much else,and I couldn't find a lot on the internet too,can anyone explain this to me,or is it just too much complicated math?

| How does boil-dry protection in electric kettles work? Posted: 16 Jan 2019 07:15 AM PST I have known how electric kettles shut off after water boils -- with the help of thermostats. The water vapor heats the thermostat, causing it to be bent (in case of the mechanical one), finally causing shut down. I recently bought a water kettle which had boil-dry protection as well. I could not understand how boil-dry protection in that device works. If thermostat is also at play here, how could hot air significantly heat the thermostat? [link] [comments]  |
| Posted: 16 Jan 2019 07:13 AM PST I wanted to build myself a little solenoid cannon for fun, and wanted to calculate the acceleration that a ferromagnetic projectile would undergo with different parameters (turns, current, projectile size, etc.). While searching I came across people stating that a ferromagnetic material would experience no net force in a uniform magnetic field. If this is the case, how have I seen that exact process occur in solenoids before? [link] [comments]  |
| What is the average intensity of radiation released from the Earth? Posted: 16 Jan 2019 06:48 AM PST I'm pretty terrible at science, but I've been trying to learn a little bit about climate change. One of the concepts that's been explained to me is that when greenhouse gases are added to the atmosphere, the Earth's surface temperature will gradually increase until outgoing and incoming radiation are in equilibrium with each other. One person who I talked to over the summer seemed to indicate that in order for outgoing and incoming radiation to be in equilibrium with each other, the Earth would have to emit 340 W/m2. And I can see in this diagram that the total amount of incoming solar radiation is indeed about 340 W/m2. But more recently, someone else told me that the Earth only has to emit 240 W/m2 in order for incoming and outgoing radiation to be in equilibrium with each other. Because the diagram also shows the total amount of reflected radiation as 99.9 W/m2, this seems to make sense. "Reflection" and "emission" are separate processes, right? So would it be accurate to say that the total amount of outgoing radiation from the Earth is 340 W/m2, but that the total amount of radiation emitted from the Earth is only 240 W/m2? Am I putting all of that together correctly? [link] [comments]  |
| Posted: 15 Jan 2019 02:04 PM PST I apologize if this post doesn't belong here. I attempted to do my own research and I'm pretty sure this is a faulty claim. Her whole argument was that "consciousness is not understood" and that modern Neuroscience thinks of the mind as non-physical. She's currently studying alternative medicine. Can someone shed some light on this, given that "consciousness isn't fully understood?" [link] [comments]  |

| Is the universe’s rate of acceleration increasing, decreasing, or steady? Posted: 15 Jan 2019 04:06 PM PST So I know the current scientific consensus is that the universe is expanding at a rate that is accelerating. My questions are: Is this rate of acceleration steady? Would a decreasing rate of acceleration suggest that some day the universe may start condensing? Do we have this information, or do we even have a way to calculate it? [link] [comments]  |

| What do particle accelerators do? Posted: 15 Jan 2019 03:32 PM PST I recently saw someone on how there are plans on building a particle accelerator significantly larger then the LHC and it made me realize. I don't actually know what they do. Do they provide energy? Or give us a look inside an atom? Or do they have multiple uses? [link] [comments]  |
