- Are neutrinos and antineutrinos identical?
- When a diverging lens is placed in a material with a higher index of refraction than the lens's material, does it behave like a converging lens?
- If I were to drink something that is usually injected (morphine, heroin etc.) would the effects be the same as if I were to inject them? If not, why?

| Are neutrinos and antineutrinos identical? Posted: If neutrinos carry no charge, and an antiparticle is simply the opposite charge, are neutrinos identical to antineutrinos? Do they behave and interact differently in any ways? [link] [comments]  |
| Posted: Say a glass diverging lens is placed in liquid diamond and an observer inside the medium looks through the lens. Is it like looking through a converging lens now? [link] [comments]  |

| When did people realize that stars don't last forever? Posted: I've tried to google the answer, but I couldn't find anything. I know that people understood that the sun works by nuclear fusion in 1929 or so. Before then about 100 years earlier, they had an idea that our sun is made out hydrogen and helium, but I guess they didn't understand how it worked. I am asking this because I found a poem published in 1881 that talks about the Big Bang, the extinction of all stars, and ultimately the heath death of the universe. All those things were discovered 50-100 years later. [link] [comments]  |

| Do Animals Have A Sense of Rhythm? Posted: Do animals perceive a beat or a rhythm the same way humans do? Can they react to it or move to it perhaps? [link] [comments]  |
| Bought a helium balloon today, went outside in the cold, what happened? Posted: got a helium balloon for my 3yo son. it was warm inside the store, outside it's pretty damned cold, freezing or below. inside the balloon was firm, like it was fully inflated. in the less than 30 seconds walking to the car, it had lots of slack in the balloon itself like it had lost around 30% or so of it's helium volume. once inside the car, the balloon firmed back up like it had been fully inflated. what occurred?

| Does air temperature and humidity affect the propagation of sound waves? Posted: I am not only referring to its speed, but also to its dispersion and attenuation, e.g. I feel that sounds seem more 'crisp' and travel further during the cold and dry winter months. [link] [comments]  |
| Posted: I'm a student, currently 2nd year of physics. We're doing complex integration and I just can't grasp visually what we're actually doing. Is there a comparison with surfaces under real functions, or is it something completely different where I should just deal with the fact that I need to look for residues and integrate over closed surfaces?

| Is the Peach-Koehler-Force the same for a edge dislocations and a screw dislocation? Posted: My Burgers vector is b=(b,0,0), the edge dislocation is ds=(0,ds,0) and the screw dislocation is ds=(ds,0,0). When I try to work it out with dK=[σb x ds] (where σ is the symmetric stress tensor) I get dK=(σ_zx * b * ds, 0 , -σ_xx * b * ds) for the edge dislocation and dK=(0 , σ_zx * b * ds, -σ_yx * b * ds) for the screw dislocation. My textbook says that those two are equal but offers no explanation and I can´t see why those two should be equal. [link] [comments]  |

| How do we know what sounds hieroglyphs make? Posted: Might not be directly ''sciency'' but didnt know where else to ask. How do we know for example that the word Nefer, wich is egiptian for Good sounds like nefer? Dont know if im expressing myself correctly, but imagining that in 1000 years, someone found our alphabet, they would have no way of knowing what sound the letter A does right? Assuming no one who knows the language is left [link] [comments]  |
