| Why do some wind turbines have textured edges ?(image in text below) Posted: 04 Oct 2018 09:56 PM PDT I noticed these raised edges on the blade of a wind turbine in this video from Jeff Bezos's Instagram. What are they for? [link] [comments]  |
| Posted: 04 Oct 2018 09:18 PM PDT What are some orbital phenomena that our models of astrophysics predict as being possible, but we simply haven't found an example of any known planet in the universe having yet? I'm referring specifically to things orbiting a planet in the vein of rings, moons, interactions between planets, etc., but interesting orbits of planets themselves are fair game too.

| What would atmospheric matter-antimatter explosion look like? Posted: 05 Oct 2018 03:01 AM PDT I'm just curious how would a massive matter-antimatter annihilation event (say, 1000 kg of each) look like in the Earth's atmosphere? Would it be similar to thermonuclear explosion? Would there be a massive outburst of high energetic photons or something like that? How much radiation hazard there would be? Would we see a mushroom cloud? [link] [comments]  |

| Does the oxygen abundance around a plant increase in a closed environment? Posted: 05 Oct 2018 07:25 AM PDT Hi, I'm aware that this topic is probably far easier than what is normally discussed in this group but a helping hand would be very much appreciated. So I'm writing a lab on the effect of varying light intensity on photosynthesis rate. And i'm controlling the light intensity by the distance to the lamp, and photosynthesis rate by measuring the o2 abundance using a vernier. And I put a specific plant inside of a ziploc bag, but after each trial (I did 5 trial each for 5 increments), the oxygen abundance in the bag remains the same if not decreased. I have no idea how to explain this in conclusion/evaluation section. Any explanations on why this could be? I hypothesized that it should increase with closer distance to the light source as the plant will have more available light energy. In the ziploc bag, I do see condensation. [link] [comments]  |
| How does optical activity work at the atomic scale? Posted: 04 Oct 2018 07:06 PM PDT I am trying to get a good grasp on the use of circular dichroism spectroscopy in biology. So far everything makes sense, but I don't quite understand what exactly causes chiral molecules to exhibit optical activity, and I feel like that is important for a complete understanding. I read a page that says chiral molecules rotate linearly polarized light when the light interacts with the molecule's electron cloud. But what /exactly/ is happening? What about this interaction causes the rotation of the plane of the electric field's oscillation? And why doesn't the orientation of the chiral molecule matter? Our hands are chiral, but the shadow of my hand if my palm is facing me looks different than if my palm is facing away. Wouldn't the random orientation of the molecules in solution affect the interaction with light? Sorry if these questions are confusing, I can reword if necessary. I am not a physicist [but I wish I was :'( ] [link] [comments]  |

| When an atom is split is the energy released coming from the gluons? Posted: 05 Oct 2018 05:21 AM PDT Gluons seem really interesting, I've learned that they provide 99% of the atoms mass but somehow Higgs get a lot of credit for their 1%. It just got me thinking about gluons, after googling the subject it all seems pretty vague. [link] [comments]  |

| What’s the cellular cause of glaucoma? Posted: 04 Oct 2018 03:58 PM PDT I've been researching glaucoma for school, I can't seem to find the specific causes for it. I know that close angle is caused by the iris blocking the drainage angle. But open angle is always referenced as a failure to drain due to blockage, I think it's because calcium builds up in the drainage, I don't have precise proof but is it because of calcium build up in the drainage angles. The question I need answered is what malfunctions on the cellular level but any information is helpful? [link] [comments]  |
| Are mammals the only type of animals that can get fat? Posted: 04 Oct 2018 02:47 PM PDT I've heard of fat people, dogs and cats but I've never heard of a fat lizard, bird or insect. [link] [comments]  |

| Has the amount of radiation earth puts out into space risen due to humans? Posted: 04 Oct 2018 03:52 PM PDT Do our nuclear devices, electronics, atomic blasts, etc. effected the total radiation that earth gives off over the course of the past 300 years? [link] [comments]  |
| Do different types of cells have chromosomes with different initial telomere length? Posted: 04 Oct 2018 09:29 AM PDT Otherwise what allows for the difference in lifespan between a neuron and an epithilal cell for example? [link] [comments]  |

| Does nuclear radiation have a "signature"? Posted: 04 Oct 2018 09:41 AM PDT Like if I took something from an area that was highly irradiated like Chernobyl of Fukushima could you examine in and just by measuring the radiation could you tell where it was from? [link] [comments]  |
