| AskScience Panel of Scientists XIV Posted: 30 Jan 2016 08:55 AM PST Please read this entire post carefully and format your application appropriately. This post is for new panelist recruitment! The previous one is here. The panel is an informal group of redditors who are either professional scientists or those in training to become so. All panelists have at least a graduate-level familiarity within their declared field of expertise and answer questions from related areas of study. A panelist's expertise is summarized in a color-coded AskScience flair. Membership in the panel comes with access to a panelist subreddit. It is a place for panelists to interact with each other, voice concerns to the moderators, and where the moderators make announcements to the whole panel. It's a good place to network with people who share your interests! You are eligible to join the panel if you:
Instructions for formatting your panelist application:
Ideally, these comments should clearly indicate your fluency in the fundamentals of your discipline as well as your expertise. We favor comments that contain citations so we can assess its correctness without specific domain knowledge. Here's an example application: Please do not give us personally identifiable information and please follow the template. We're not going to do real-life background checks - we're just asking for reddit's best behavior. However, several moderators are tasked with monitoring panelist activity, and your credentials will be checked against the academic content of your posts on a continuing basis. You can submit your application by replying to this post. [link] [comments]  |
| Posted: 14 Jul 2016 05:00 AM PDT Hi everyone. I do theoretical and computational work on supernova neutrino oscillations and nucleosynthesis. I have worked with trying to predict the neutrino output of a star undergoing the early stages of supernova, and am currently working on a project that will examine the feedback process between neutrino oscillation and nucleosynthesis in supernovae. I should be available between 12-2 EDT (17-19 UTC). AMA! [link] [comments]  |
| What would have happened to Oil if humans had never drilled it? Posted: 14 Jul 2016 03:24 AM PDT Does it become a rock if left alone? Become a gas that bubbles though the cracks to the surface? or has not enough time passed yet to say? [link] [comments]  |

| Why does a wet washcloth stick to things, even a fairly smooth tiled shower wall? Posted: 13 Jul 2016 11:02 PM PDT Currently there is a battle taking place over in ELI5 over this very question. One group is claiming molecular cohesion and the other is claiming a vacuum is created. Could you folks give us a hand? [link] [comments]  |
| Why do our eyes become red when we cry? Posted: 13 Jul 2016 08:56 PM PDT |
| How do electromagnetic waves work? Posted: 14 Jul 2016 04:09 AM PDT I understand that the electromagnetic wave is made up of an oscillating pair of electric and magnetic fields that interact with each other. So how do the fields interact and how can this be visualised? I've seen diagrams that depict the two waves shifting back and forth at 90 degree angles in a direction, though don't fields occupy a 3 dimensional space? Meaning that the electromagnetic wave is essentially made of two twisting spirals of potential magnetic and electrical potential in which the electrical field is where the magnetic field is not? On another note, what are these fields made of? Are they particles or simply spaces of energy, if so, how do the waves have a direction of movement? Any kind of in-depth explanation would be hugely appreciated. [link] [comments]  |
| How do people debug software written for large hardware systems? Posted: 13 Jul 2016 06:31 PM PDT Not sure if I worded the title correctly, but I am genuinely curious as to how software is debugged for something like SpaceX Rockets. How do you test your changes for something like starting the rockets, or the stabilization of the rocket upon descent? How can they be sure what they write is actually working correctly without having it physically tested? A smaller example would be FitBit. FitBit has a sleep monitoring system. How do you debug that? If someone makes a change to the sleep monitoring software, wouldn't the only way to debug it be to actually test it on a sleeping person and get the data back to make sure your change is working?

| Is there much variance in the size of people's eyeballs? Posted: 13 Jul 2016 09:29 PM PDT I notice that some people have "big eyes" but it really seems like the eye openings are bigger, some are surrounded by darker pigment, or the women are wearing mascara, and some eyes are set in at different depths - all of these things can give the appearance of having larger eyes. However, most things on our bodies do have variance so it makes me wonder if the actual eyeballs are of significant sizes. A lot of middle eastern people, especially Arabs have big looking eyes. Could their eyeballs be bigger (on average?) [link] [comments]  |

| Question about about insect gigantism? Posted: 13 Jul 2016 06:17 PM PDT We know that scientist mostly conclude or assume that insects and plants during the carboniferous period grew so large because of the increased level of oxygen at the time.my question is have scientist tried to prove this? Could they build a botanical garden-like ecosystem and insert cockroaches, dragonflies, etc. And over time increase the oxygen in the ecosystem and over the course of 20-25 insect generations see an increase in size maybe? Thanks [link] [comments]  |

| If you put a hole in a mobius strip, is it still a mobius strip? Posted: 13 Jul 2016 02:58 PM PDT if a mobius strip has one edge and one side, then if you punch a hole in one, thereby giving it 2 edges, is it still really a mobius strip? [link] [comments]  |
| How do Significant Digits and Standard of Error work in other Bases? Posted: 13 Jul 2016 07:51 AM PDT I have a pretty solid understanding of significant digits in base 10. What are the repercussions of using significant digits in a small base (eg base 2) or a large base (eg base 60)? Bonus: how to keep the same significant digits (in meaning) when switching bases.

| Posted: 14 Jul 2016 05:36 AM PDT What's the scientific evidence that hair dye can cause (or exacerbate) hair loss? I've googled and seen claims to the effect that there is zero reason to worry that hair dye can cause hair to fall out, but I'm not sure how reliable those claims are. [link] [comments]  |
| Would 100 degree steam really burn you worse than 100 degree water? Posted: 13 Jul 2016 06:30 PM PDT I recently read the claim that steam will burn you worse than water, because it has more energy per kilo, but wouldn't the much lower density of steam mean the opposite was true? [link] [comments]  |
| How do the lines of light coming from a light source come about? Posted: 13 Jul 2016 08:23 PM PDT Like when you stare at a strong light you can see rays of light extending a little around it. It can be even more prominent when you are nearsighted. Bonus question, and the real reason I posted this question: explain why when i saw my phone flashlight reflected in the tv it had exactly 4 rays and all perpendicular. One line vertical and one horizontal. Moving my head and phone did not change the orientation of the rays. [link] [comments]  |
| [Physics] What keeps protons and electrons from taking the same space? Posted: 13 Jul 2016 03:47 PM PDT After watching a video with Richard Feynman where he briefly talks about normal forces being a result of electromagnetic forces, what is the force "pushes back" protons and electrons when they touch each other? If they attract more the closer they are to each other, shouldn't there be something that pushes them away when they are touching or colliding? Does this never happen, or does something completely different happen? [link] [comments]  |
| Does a battery weigh more if it is charged? Posted: 13 Jul 2016 04:34 PM PDT Would a charged battery weigh more than a discharged one. (I'm thinking the type of battery in phones.) If the change is small, how big would a battery have to be for it to be noticeable? [link] [comments]  |
| Posted: 13 Jul 2016 03:06 PM PDT Some people say the pain giving birth is equivalent to breaking a certain amount of bones or whatever, but surely breaking bones is less painful for some people than others? Isn't pain relative to each person? [link] [comments]  |
| Why do we not have lightning farms? Posted: 13 Jul 2016 02:14 PM PDT I live close to these towers and see storms like this frequently. Seems like the towers could be doing a bigger job. What's missing from my utopian lightning farm plan? [link] [comments]  |
| What is a Rubens Coil and how to make it? Posted: 14 Jul 2016 02:08 AM PDT Hello Reddit! I'm a high school student in South Korea and am currently researching how magnetic fields effect ant behavior. I've searched on the internet for ways to make a device that generates an even magnetic field that I can adjust the strength of. I found something called a Rubens Coil. Unfortunately I can't find any information on what it is and how to make it. Could someone explain what it is and how to make it? And, if possible, could someone suggest another method to make a device for this research? [link] [comments]  |
