How do modern nuclear reactors avoid service interruptions due to slagging/poisoning? Posted: 30 Nov 2017 03:14 AM PST Was reminded of a discussion I had with my grandfather (~WW2 era nuclear science engineer) about how problematic reactor poisoning was in the past and especially slagging. I believe more than a few of the US fleet of commercial reactors are at or are already surpassing 60 year total runtime licenses, was it just better designs or something else? submitted by /u/zynix [link] [comments]

What is happening to engine oil that requires it to be changed every 6000km (3000miles)? Posted: 29 Nov 2017 08:09 AM PST Why does the oil need to be changed and not just "topped up"? Is the oil becoming less lubricating? Edit: Yes I realize 6000km does not equal 3000miles, but dealers often mark these as standard oil change distances. Thanks for the science answers! submitted by /u/paramedic-tim [link] [comments]

What is ATT or Verizon's average cost to deliver 1 GB of data to my smart phone? Posted: 29 Nov 2017 11:46 AM PST I think this would call on Computer Scientists and Network engineers, with domain knowledge in cell tower installation/setup. I want to know what ATT or Verizon's average cost is assuming data transfer is over a cell tower in the lower 48 US. I'm not interested in capital investment numbers because these eventually are fully subsidized through pricing I would think is obvious. I'm just interested in the number it costs to transmit the data over all the network hardware to my phone. Also I'm mostly talking about the last mile or endpoint node to my phone. I realize depending on where the data is originating the costs can vary, at least it would be nice to have some explanation of how numbers add up in the ISP world. So we can be more educated consumers. EDIT: Many have brought attention to operating/maintenance/employee costs. While these costs are substantial, they are relatively fixed or stepped and heavily subsidized. I want to know a big telcom's average variable costs on delivering data from point A to B, if both A and B are in the US and B is an endpoint like my cell phone. submitted by /u/throw_it_in_the_lake [link] [comments]

Are ant queens aware of the amount of ant types necessary for their colony or is it genetically programmed ? Posted: 30 Nov 2017 02:40 AM PST For clarity: Perhaps the ant queen is genetically programmed in a way to produce 3 different kinds of ants in equivalent production. If 10 ants of one type die, does the queen accommodate in her production? submitted by /u/Gray_Fawx [link] [comments]

Late Thanksgiving question: Is roux an emulsifier as well as a thickener? Posted: 30 Nov 2017 05:25 AM PST Oil and water don't mix unless you use something like a surfactant or emulsifier. When making my Thanksgiving gravy, I got to thinking, I'm mixing oil and flour, and then mixing that with water. Yes it's thickening it, but it's also holding it in suspension(as long as I follow the recipe ). Furthermore is it the roux or simply the wheat flour? And what is it about the wheat flour, simply the surface area giving enough to bind to? submitted by /u/SenorPuff [link] [comments]

Turbulence is a famously difficult problem. What makes it difficult? To what degree can it be understood by theoretical, numerical, or physical modeling?

How would a planet be shaped to have a area where the sun never sets and a place where the sun never rises?

Given that you can do Lorentz Tranformations is time a vector quantity? Posted: 30 Nov 2017 03:52 AM PST If time can spin, because time isn't universal and special relativity means it must spin to conserve speed of light while allowing you to do some stuff with time dilation and relative movements etc. does that mean time is a vector quantity, not a scalar quantity, as its not progressing in the same direction for everyone. Also, is there a limit to how much it can spin around? There must be, surely, otherwise things could travel back in time, which would be crazy, so where is this limit? submitted by /u/LjSpike [link] [comments]

Where do the physical electrons in piezoelectric produced current originated from? Posted: 30 Nov 2017 12:39 AM PST I have a complete understanding of how a deformation in a piezo material produces a potential difference and that potential difference drives a current. What I would like to know is where does electron flow come from? Is there an oxidation that produces an election and a corresponding reduction on the other end of the crystal? submitted by /u/IHateTexans [link] [comments]

If too many users are crowding my LTE network, can my provider build towers/base stations or do they need to need to buy more spectrum? Posted: 28 Nov 2017 07:39 AM PST Hi all, I'm trying to get a better understanding of wireless spectrum, specifically the (non-5G) mid-band. I understand there is a maximum data transmission rate for a given frequency, but I'm trying to understand how crowding & noise limit the capacity. I also understand that deployment of 5G will alleviate many capacity issues but will be cost-prohibitive in low-density areas. Would love to hear your expertise or be pointed to your favorite resources. Thanks much! submitted by /u/watchdog211 [link] [comments]

Does your immune system become generally stronger or does it only build up against things it's exposed to? Posted: 28 Nov 2017 05:37 PM PST I know that exposure builds your immune system, but does your immune system also become more resistant to things that it hasn't been exposed to?

How "green" is the life cycle of electric cars end-to-end compared with traditional cars? Posted: 29 Nov 2017 01:39 AM PST I was reading through the earlier post about comparisons between solar energy and traditional energy sources and it got me thinking about a similar comparison between electric cars and non-electric cars. I get that it will depend on the specific car but I was hoping for a generalised answer. I've heard it mentioned that the production of the batteries for electric cars practically outweighs any benefit. submitted by /u/Cloudsack [link] [comments]

Does water freeze differently while under pressure?

Why does Saturn's ring of debris circle in a one plane manner rather than an evenly dispersed sphere around the planet? Posted: 28 Nov 2017 06:50 PM PST So I was looking at some Nasa photos today and it got me wondering, why are gasses and debris that circle the outer regions of planets like Saturn only circling along one plane? In other words why do the rings of Saturn form a razor thin (In relation to the size of the planet) like disc around it rather than a sphere of debris around the entire planet? Another question I had was the same but in relation to black holes. Sometimes the artistic sketches show the gasses/debris around a black hole in a one plane manner and other times its portrayed more like this: https://www.instagram.com/p/Bb4nmNin3MK/?taken-by=nasa Can someone explain if black holes are actually attracting debris along a one plane manner or in all directions as I'd assume would be more realistic? submitted by /u/herbandspiceforlife [link] [comments]

What determines Battery charge efficiency? Posted: 28 Nov 2017 01:57 AM PST Hi Redditors, This is my first post here. I've been trying to understand batteries and have found most sites I found either had explanations that were too shallow or too long and specific. I'm wondering if someone can point me to the right direction? The topics I have of interest are: 1) Battery charging - Batteries charged only up to 80-90% as opposed to 100% increase in usable life and total charge cycle capacity? Why? - What determines the maximum Jolts per second a battery can discharge or be charged by? What is the limit? Does it just explode if you give it too much juice? - There seems to be two-fold decay in the charging efficiency. First as you increase the jolts per second you are charging the battery with and second as the battery nears fuller capacity you also lose charge efficiency. I.e. more electricity "warms the air" as charging speed and battery capacity charged increase. Specifics on these factors? Are there more? 2) Battery chargers - There is also an inefficiency (electricity lost) in charging electronics. Is it better to charge a battery from another battery? Or is it the same as grid to battery? What is the inefficiency in charging caused from? - What limits the charging speed? Is it the charger or the battery receiver or both? 3) Do the answers above depend on the battery type you are using or do the rules hold true for all battery types? Discuss! submitted by /u/aganchev [link] [comments]

Why does the 1st Ionisation Energy NOT decrease between Group 1 and Group 2 elements? Posted: 28 Nov 2017 07:03 AM PST So I've read that, between the Group 5 and Group 6 elements of the same period, the first ionisation energy decreases because in group 6 the electron is removed from a full orbital, so the mutual repulsion of the two electrons in the orbital makes it easier for the electron to be removed. However, surely this scenario is the same as for group 2 elements, where 2 electrons share the s-orbital? So my question is, why is there a drop in first ionisation energy between group 5 and group 6 elements of the same period, but NOT between group 1 and group 2 elements? submitted by /u/ThatCosmicGuy [link] [comments]

Does tectonic movement destroy ancient asteroid craters? Posted: 28 Nov 2017 02:31 AM PST This might be a silly question with an obvious answer, but hear me out. Plate tectonics are responsible for shaping and moving the crust of our earth, correct? If they change the shape of our earth so much, how can we know which craters cause certain extinctions? For example the Chicxulub Crater, which supposedly caused a mass extinction, might not actually be as old as we assume it is. Wouldn't the moving plates, after millions of years, change the topography so much as to make craters unrecognizable? How do we know the Chicxulub Crater isn't a more recent addition to earth's landscaping? Edit: fixed a fragmented sentence. PS. this isn't meant to sound precocious or knit-picky. I have very little knowledge of this subject and I'm genuinely curious. submitted by /u/Jean_the_wanderer [link] [comments]

How do you increase energy of photon emitted from magnetic resonance relaxation in MRI? Posted: 28 Nov 2017 02:55 AM PST I wonder if there is a way to increase photon energy, because I want to use the emitted photon to something else. I have read from Hoult (2009) that 1,5 T are only enough to generate 2 x 10−7 eV. Is it by increasing the magnetic field (B), radiowaves, or both? Also is there a definite reference that state the lethal dosage of magnetic exposure to human? Thank you References: Hoult. 2009. The origins and present status of the radio wave controversy in NMR.

Do stars appear smaller over time? Posted: 27 Nov 2017 08:34 PM PST Because the universe is expanding we would expect the stars to appear smaller after some time, is that what we have observed? (If not, could the red shift of light dependent on how far a star is exist because light somehow needs energy for travel or loses it in some way? I'm not a physicist so maybe this is a completely stupid idea, but the accalerated expansion idea still doesn't have a well explained cause and the biggest reason we think accalerated expansion is a thing is because of the red shift which could possibly be because of other causes.) submitted by /u/Klogavis [link] [comments]

How do chemical reactions work on the quantum level? Posted: 27 Nov 2017 04:28 PM PST I'm an undergrad student studying chemistry and biology where (especially in organic chemistry) we do a lot of "arrow pushing" (i.e. drawing arrows to signify where electrons travel during a chemical reaction). Earlier today I was watching a video in which Sean Carroll (physicist) goes on to explain how electrons actually form a "cloud" of probability around an atomic nucleus, where according to its wave function you can predict where you might find that electron if you went looking for it. He also stated, most importantly, that the electron is actually just a cloud of probability until you look for it, that the electron isn't anything more than a wave function until we look. What does that mean for my arrow pushing? If the electron is just a wave function does it collapse when chemical bonds are formed? What exactly goes on in this sense? submitted by /u/TimeSpace1 [link] [comments]

Does the body produce adrenaline during surgeries where it is cut open? Why or why not? Posted: 28 Nov 2017 06:12 AM PST We all know that when you get into horrific accidents and get a limb severed (or something on a similar scale), the body produces a ton of adrenaline to help you numb the pain and puts your body in a fight or flight mode to ensure its survival. But in a medical surgery when you're properly sedated for (for example) an amputation where your limb is going to be severed, does your body produce adrenaline as well?
