| Posted: 07 Apr 2017 09:33 PM PDT Say there is a large mass. Is gravity equally distributed among this mass or are there "hot spots" so to speak? Edit: Many of the answers are in regards to the Earth, but what about Stars, Black Holes, Nebulae, and other space anomalies? [link] [comments]  |

| Posted: 08 Apr 2017 04:04 AM PDT I find it quite odd that solvents like toluene or xylene will evaporate faster than water at room temperature, but still need to reach higher temperatures to start boiling. I have a feeling it has something to do with their heat capacity? Please explain this to me. [link] [comments]  |
| Posted: 07 Apr 2017 04:25 PM PDT 1) Why is it not possible to measure the position of a single quantum particle multiple times? (aka a video) Would we be able to then track it's momentum? 2) If the answer to the above is that it pops in and out of existence, how exactly does that happen? 3) How large of a field would you need to track a single quantum particle? 4) Would that be able to be done on Earth? Would we have to develop a large science facility in space somehwere? 5) Would it even be possible to build a machine large/small enough to do this? [link] [comments]  |

| What is the connection between Majorana Mass and a Majorana Particle? Posted: 08 Apr 2017 04:25 AM PDT i have read that a particle having a majorana massterm doesnt mean the particle is a majorana particle. but doesnt the direct coupling of the particle to ints antiparticle imply that? and if not, why would neutrinos being majorana particles support the seesaw mechnism if there isnt a connection between majorana mass und majorana particle?

| How are gaseous elements harvested and purified? Posted: 08 Apr 2017 07:20 AM PDT I've read about third world communities harvesting methane from livestock. They then use that for cooking and heating water. Harvesting methods must capture impurities-dust as well as large volumes of other gasses. How would you refine a gas that's harvested like this?

| Why is the water molecule shaped like a V instead of an I? Posted: 07 Apr 2017 02:07 PM PDT In other words, why the oxygen-hydrogen covalent bonds are one besides the other, instead of being opposites around the oxygen atom? [link] [comments]  |
| Can we predict IR spectroscopy bands? Posted: 08 Apr 2017 06:05 AM PDT Is there any way of predicting the ir bands on an arbitrary molecule without solving the whole schrödinger eq numerically? Is there any simplifications where we can use for example bond length or things like that to predict ir bands position with reasonable accuracy? [link] [comments]  |

| is antimatter REALLY traveling backwards in time? Posted: 07 Apr 2017 03:13 PM PDT I've read in a number of places that antimatter is really just normal matter traveling backwards in time. If this is true, wouldn't it explain why there's so little antimatter in the universe since any created during the big bang would have gone to a point before it? [link] [comments]  |
| Does the Moon have a different 'ground' voltage potential relative to Earth? Posted: 07 Apr 2017 06:48 AM PDT If earth ground is referenced as 0V, does the Moon as a whole have a different potential relative to earth ground? If you were to connect the Moon to Earth with a conductive line, would there be an electrical flow? [link] [comments]  |

| Why does metal straighten right before breaking when a direct current is flowing through it? Posted: 08 Apr 2017 03:27 AM PDT Hi folks, Danish highschooler here. For my exam project, we have conducted an experiment where we tried to prove different types of resistances in metals by flowing a current through it. What we did was put current through a wire positioned in the air and measured the amount of current that went through it. I had to take evidence, so I filmed a slow-mo video with my camera and when we put through direct current I noticed that, when we increased the amp, the metal heated up and right before breaking it straightens it self. My first theory was it was the metal becoming so hot that it started to liquidize, but that didn't really make sense because the density of the metal would be higher and wouldn't cause it to snap. I have a video of the experiment here: https://www.instagram.com/p/BSlyYHrl6Em/ Can someone explain to me, why it snaps and why it straightens? Thanks in advance. [link] [comments]  |

| Posted: 07 Apr 2017 08:14 AM PDT So, this seems like a silly question, but I feel like it pertains to how microwaves work. In a conventional oven, all items in the oven absorb from the same source of radiated heat. But microwaves would be different. Is there a formula to figure out the time needed to cook n items where the standard cooking time of one item is t? [link] [comments]  |
| Posted: 07 Apr 2017 08:06 PM PDT With technology creating material like this that is already far lighter than air and floats easily, what is the obstacle keeping us from using it to make fabrics that can float like this? Studios and designers would kill for fabric like that, so I can't imagine cost is the obstacle here, but I could be mistaken. [link] [comments]  |
