- Atomic charge, isotopes, and the Rutherford model of the atom were discovered in the 1910s, but the neutron wasn't discovered until 1932. So how did people account for atomic mass (e.g., the differing atomic masses of isotopes) in the 1920s?

| what does it mean to take something to the i power? Posted: 11 Nov 2018 06:32 AM PST I have been reading up on Euler's Formula of eiπ +1 =0 and everything else makes sense other than the ei part. how does one take something to the power of i, which is the √(-1)? Like, how. Its imaginary. I just can't wrap my mind around it. [link] [comments]  |

| What genetic factors determine how many beans a pod will have within a given species? Posted: 11 Nov 2018 04:01 AM PST For example, in edamame, the soybeans typically have two or three though there's still some variance on top of that. In other species, e.g., cocoa, the number within a pod can vary more wildly, and I found the beginning pages of one old study discussing this but it doesn't go into much depth. I'm not interested in the differences between species though, but within a species, what genetic factors determine how many beans one specific organism will have? [link] [comments]  |

| Posted: 10 Nov 2018 05:03 PM PST Basically, does the top of the atmosphere (or any boundary between two atmosphere layers) move like the ocean's surface in this gif: https://i.gifer.com/2ycJ.gif (minus the rain) [link] [comments]  |
| What is the process by which a forest biome becomes a desert? Posted: 10 Nov 2018 10:57 PM PST We hear about how the Sahara desert was once a lush forest. But do biomes change quickly or slowly? Is there a single catastrophic event, such as a flood, which disrupts the environment, or does it occur as weather patterns change over thousands of years? Wondering how quickly the same could happen to beautiful, smoky California. [link] [comments]  |
| Does world war era battlefield soil differ from a soil that hasnt been batteled on? Posted: 11 Nov 2018 06:34 AM PST How different is the soil of Verduns battlefields today compared to regular soil of a similar area? Can you tell the difference of the soil of WW1 battlefield and WW2 battlefield? [link] [comments]  |
| How do imaginary numbers play into the real/physical world? Posted: 10 Nov 2018 05:25 PM PST I was reading up on imaginary numbers and a source stated that they started out purely imaginary and for mathematical purposes and some stuff with Euler's equation (that I don't really understand except that it has to do with complex planes or something), but how does it govern physical things, like springs or circuits or other things with some sort of resonance. If it's just imaginary, how is it able to dictate/show non-imaginary things? [link] [comments]  |

Posted: 10 Nov 2018 09:56 PM PST http://nymag.com/intelligencer/2018/10/un-says-climate-genocide-coming-but-its-worse-than-that.html Is this just fear mongering? I read the Climate report by the UN but i'm not too sure how reliable it is. Are we really done for? [link] [comments]  |

| How do we know that a given reaction mechanism actually describes what's going on in a reaction? Posted: 10 Nov 2018 03:35 PM PST I understand that we can do things like IR, NMR, melting point and whatnot to identify reactants and products, but how are reactive, temporary intermediates identified? how do we know for sure that a reaction actually proceeds the way an electron pushing mechanism shows? related, how do we know the structures of reaction intermediates? in brief, what processes are used to test if a reaction mechanism describes a reaction, or if an intermediate actually forms?

| Posted: 10 Nov 2018 03:24 PM PST It's described, that lim(dS) = 0 for T against 0, for perfect, crystalline structured substances. My question is, that from my understanding no particles are able to move when they are cooled down to 0 Kelvin (since thermal energy is just a statistical symptom of kinetic energy), so based on that shouldn't every substance - perfect or not - in a closed system get to lim(ds) = 0? I would assume, that this example system would than be in a state, that is not changeable, because the particles aren't able to move due to their lack of kinetic energy and therefore aren't able to adjust their positions. That would result in dS = 0 as there will be no possible changes. [link] [comments]  |

| Posted: 10 Nov 2018 11:19 AM PST I was thinking about a fictional story where the main character could generate a lot of heat like the Human Torch from the Fantastic Four. This character was going to make a secret underground base by picking out a mountain and melting a cave into it. However, since it needed to be secret he couldn't just let the melted stone flow out the front. It was at this point that I realized I was assuming melted rock would be more dense than the original. In other words, melting the rock and then allowing it to cool would somehow leave space even though none of the melted rock was allowed to flow out of the cave being created. Is this true?

| How were the long landforms outside of the Polish, Lithuanian and Kaliningradian coasts formed? Posted: 10 Nov 2018 01:19 PM PST I'm talking about the long almost circular landforms on either side of Kaliningrad (zoom out). I asked my geography teacher, she didn't know, but suggested maybe it was sand being washed up. What are they and how were they formed? [link] [comments]  |
