| If defibrillators have a very specific purpose, why do most buildings have one? Posted: 03 Oct 2018 07:39 AM PDT I read it on reddit that defibrilators are NOT used to restart a heart, but to normalize the person's heartbeat. If that's the case why can I find one in many buildings around the city? If paramedics are coming, they're going to have one anyway. [link] [comments]  |
| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 03 Oct 2018 08:12 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Biology, Chemistry, Neuroscience, Medicine, Psychology 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]  |
| What is the force carrier of a magnetic field? Posted: 03 Oct 2018 07:07 AM PDT While watching a video explaining electromagnetism, it was stated that the force carrier is the photon. However, my understanding of photons is that they do not contain a charge and are therefore unaffected by magnetic fields. The video mentioned nothing of moving electrons being a force carrier within a wire. How can photons be the force carrier and yet light is unaffected by magnetic fields? What is the relationship between the nuclei of magnetic elements and the electron, if they are unified under the same force? Any clarification, simple or complex, would be greatly appreciated!

| what could cause a peak at 642nm in an H2 spectrum? Posted: 02 Oct 2018 07:54 PM PDT I have a hydrogen gas spectrum tube in a spectrum tube power supply. I have one end of a small bundle of fiber optic strands pointed at the spectrum tube, and the other jammed into the cuvette holder area of a PASCO spectrometer, which is communicating with an iPad via Bluetooth. The 656 nm line is supposed to be there, but I have no idea why I have a peak at 642 nm. What could produce that? spectrum here [link] [comments]  |
| Does adding more heat to a pot of boiling water make it cook things faster? Posted: 02 Oct 2018 04:45 PM PDT I have to win an argument. The idea starts off with somebody boiling a decently large sized pot of water. When small amounts of bubbles start to form and rise is what qualifies as "boiling the water". My question is, if you were to add heat and make it a rapid rolling boil, would that cook food inside of the pot faster than if the boil was less "aggressive"? An example for the food would be noodles that take up most of the space in the pot when added to the water. The person I'm arguing with says that since water boils at 100° in an ideal circumstance, the water will not (or at least nearly negligibly) cook the food faster. I think that adding more heat will make more of the water in total hotter (since I assume most of the water isnt actually at its boiling point), which will make the food hotter, which makes the food cook faster (like cooking the noodles in 6 minutes instead of 8). How does this work? [link] [comments]  |

| Do isotopes of a given element have different atomic radii? Posted: 02 Oct 2018 03:53 PM PDT While the nuclei are definitely of different sizes, does this affect the overall radius of the atom? [link] [comments]  |
| Do higher altitudes have any effect on audible pitch compared to sea level? Posted: 02 Oct 2018 04:14 PM PDT Follow up question, also what about places with high humidity? As far as music goes, unless you have perfect pitch, most people might not be able to distinguish differences since it seems relative pitch between one note to another is more important than a little deviation from a standard arbitrary root note. I figure if helium is lighter/less dense than standard air which causes pitch to go up, I didn't know if less dense air would have a similar effect and vice versa with denser more humid air if measure with a simple tuner.

| Posted: 02 Oct 2018 04:29 PM PDT I just saw a post where a new dwarf planet was found at the edge of our solar system. Should we not have found all these by now since they are closer and we are finding planets light years away. Is it not easier to find these closer celestial bodies? [link] [comments]  |

| Posted: 02 Oct 2018 07:26 PM PDT Models showing the shape of an electron orbital often show the space in which the probability of there being an electron is something like 90-95%. If this were extended not to 99% or 99.999999% but 100%, is there space in which the electron certainly won't be? [link] [comments]  |
| Posted: 02 Oct 2018 07:28 AM PDT So this is the first time I'm posting around in this sub. I don't have a degree that is related to physics, maths or any other natural science in general yet I'm really interested about the abstract topics of physics such as black holes. So could you guys please explain the answer of my question as if I'm retarded? I'm fine with the details, in fact I'd be happier if you went into detail and told me about Reissner-Nordström type black holes and the other types in general but I'd be so glad if you could use a pedagogic language that I could at least intuitively comprehend what the whole deal is about.

| Is there evidence that GR is realized with curved spaced rather than torsion or non-metricity? Posted: 02 Oct 2018 09:02 AM PDT I have heard that there are formulations of GR which use torsion or non-metricity of space and I am interested in how one would distinguish them with measurements and, as a bonus, how to imagine what non-metricity actually is. Would these different formulations potentially solve problems like dark matter or dark energy? [link] [comments]  |
