| 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? [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!

| 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. [link] [comments]  |

| Mount Agung Volcano Eruption Megathread Posted: 30 Nov 2017 06:36 AM PST Hi all, Mount Agung on the island of Bali, Indonesia, has currently been undergoing eruptions. If you have questions about the specific eruption, volcanic eruptions in general, or related topics, feel free to post your questions below! Some relevant links: [link] [comments]  |

| 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? [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? [link] [comments]  |

| Posted: 29 Nov 2017 01:45 PM PST I have been hearing criticism toward the shuttle for being terribly inefficient, yet I also heard others claim it was great for assembling the station. [link] [comments]  |
| Posted: 29 Nov 2017 11:21 PM PST I'm asking for a reason pertaining to a story, and I'm just curious as to what a world would look like to fit that criteria [link] [comments]  |

| 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? [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? [link] [comments]  |
