| Do hydrogen isotopes affect chemical structure of complex hydrocarbons? Posted: 22 Oct 2017 06:10 AM PDT Hello! I am wondering if doubling/tripling of the mass of hydrogen in complex hydrocarbons has a chance of affecting its structure, and consequently, its reactability. Furthermore, what happens when a tritium isotope decays in a hydrocarbon to the hydrocarbon? Finally, as cause for this whole question, would tritiated ethanol behave any differently to normal ethanol? [link] [comments]  |
| Posted: 22 Oct 2017 03:03 AM PDT I imagine "not far" being the tl;dr, but I was wondering how would it look from the ground? If loaded close to capacity, would it look little like a rock falling from the sky? [link] [comments]  |
| Posted: 21 Oct 2017 09:20 PM PDT Because on one hand, having children fulfills our biological goal so I'd imagine there would be less incentive to stick around if things came to that, but on the other hand there could be increased incentive to stick around to care for and protect the kids. Is there any discrepancy between the groups that becomes apparent on a large scale? [link] [comments]  |
| Why do electrons have a constant mass? Posted: 21 Oct 2017 11:28 PM PDT So as far as I understand, electrons can gain and lose a quantifiable amount of energy in the form of photons. Because photons have energy, they must have mass because having a zero mass would result in energy being zero due to E=mc2. However, this implies that electrons in higher energy orbitals would have more mass than those in lower orbitals because they have either absorbed or emitted energy in the form of photons. What equalizes the mass of the electron for the photon being either lost or gained? Also, if an electron is gaining/losing mass as photons are emitted and released, where is the charge of the electron stored? The photon isn't a charged particle/wave/whatever it is, so the electron isn't losing or gaining charge despite losing mass. Sorry for the lengthy question! [link] [comments]  |

| If you drop something on a solid, does it ripple like a liquid would except much less noticeably? Posted: 21 Oct 2017 01:01 PM PDT I thought of this when I was dropping some objects into sand, the sand would shift outwards kind of like a ripple. [link] [comments]  |

| How can we prove that earth is rotating? Posted: 22 Oct 2017 03:13 AM PDT Aside from the Foucault pendulum, how can we prove that earth is rotating? My friend showed me a video of a gyroscope which keeps its position by hours. I thought a gyroscope keeps its horizon no matter what, but with a rotating earth, it should have been seen as tilting after a couple hours. Am I not right? Do I miss something here? Is there an another way of proving that earth is rotating and round physically? (Without the satellite images etc.) [link] [comments]  |

| Why is Ruthenium's electron configuration [Kr] 5s1 4d7? Posted: 21 Oct 2017 08:28 PM PDT Why is it more favourable than [Kr] 5s2 4d6? Also what would the electron configuration for Ru 4+ look like? [link] [comments]  |

| Will sterilisation with gamma rays not make the product radioactive or destroy the product? Posted: 21 Oct 2017 09:59 AM PDT I was told yesterday that sometimes drugs are sterilised using gamma rays because some drugs can't handle being heated. Then he added that it's also used for food!? Is there not a risk of the drug, food or packaging becoming radioactive? Or will the rays not alter the drug or the food? I am also wondering if this done in very controlled facilities? But he said it was very common, but I thought it would be too expensive!? [link] [comments]  |
| Human fetal development: When does the uterus start to form? Posted: 21 Oct 2017 02:11 PM PDT I know why men have nipples, and why some men have supernumerary nipples. I know that the ovaries and the testicles started off as the same primitive structure. I know that the same erectile tissue and urethra in women combine to become the penis in men. Is there an equivalent structure to the uterus in male bodies? Or does it not start forming until later, after sexual differentiation has begun? Or does it vanish, like nipples in male mice? Are there many anatomical features that don't have an equivalent between men and women? [link] [comments]  |
| The impact of canals in a city? Posted: 21 Oct 2017 11:33 AM PDT A lot of cities in The Netherlands have canals. Example Once used mainly as a water highway for goods, now they're obviously less functional in that department. So other than aesthetics, what consequences/benefits does this have in a city? Nature wise? Health wise? Temperature regulation? Etc.. [link] [comments]  |

| Do you burn more calories when cold compared to when you are warm when doing the same activity? Posted: 21 Oct 2017 09:29 AM PDT When sitting down for example, would my body use more energy and burn more calories in the cold than it would when I was warm or would there be minimal to no overall difference?

| How do the switching mechanisms in transistors work, and how are they triggered? Posted: 21 Oct 2017 08:55 AM PDT I've been wondering for a while how the flow of electrons in a transistor was switched from one direction to the other. How does the software running on the OS interact with the hardware to manipulate the movement of electrons? [link] [comments]  |
| Why does absence of blood flow cause cell death? Posted: 21 Oct 2017 08:41 PM PDT Why don't the cells just stop working until blood flow full of nutrients and oxygen is restored (suspended animation if you will)? [link] [comments]  |
| Posted: 21 Oct 2017 09:09 AM PDT Or don't current solar panels currently work with UV light? And is there any progress towards engineering solar panels that can work efficiently in the UV range? [link] [comments]  |
