| What effects does a pear-shaped nucleus actually have on an atom? And what causes it? Posted: 27 Jun 2016 06:00 AM PDT I just saw this post in /r/science which talks about a pear-shaped nucleus. There was an article linked, but it was a bit above my understanding. So given that I was always told that an atom's nucleus is spherical, what do different shapes mean? [link] [comments]  |

| What is the difference between sand in Mars and Sand on Earth? Posted: 27 Jun 2016 05:04 AM PDT I've been looking at pictures of Mars and the sandy surface looks eerily similar to deserts on Earth. If we compare granule to granule, how different would the Mars sand be to Earth sand in terms of composition? [link] [comments]  |
| Posted: 26 Jun 2016 04:17 PM PDT For example, if you were in a dark room and you lit a match, where do the photons come from? Were they dormant in the room, or stored somehow in the chemicals of the match? [link] [comments]  |
| Posted: 26 Jun 2016 06:09 PM PDT If I was standing on mars for a lunar month (or any planet really) would I always see one side as well? [link] [comments]  |

| Is there any correlation between prefered school subject and political beliefs? Posted: 26 Jun 2016 06:35 PM PDT Something that has been on the mind for awhile, but I can't seem to find any studies nor information on the subject. I have a feeling there is possibly some correlation, but I can't be too sure. Anyone have any information on this subject? Also, this might not be science related per say, so redirect me to where I should post if not! Thanks! [link] [comments]  |
| Is there any way to measure/define smell that isn't purely allegory? Posted: 26 Jun 2016 07:06 PM PDT We measure the stimulus of all other senses: light, sound, pressure, temperature, taste, etc. Is there any form of measurement for smells? [link] [comments]  |

| What's the science behind pickling? Posted: 26 Jun 2016 11:14 PM PDT I just want to know why soaking a cucumber (or whatever you pickle) in vinegar and seasonings prevents it from going bad over a much longer scale. [link] [comments]  |
| Posted: 26 Jun 2016 07:55 AM PDT I understand what gravity assist is but I do not understand why the object using the gravity assist gains so much energy after passing into and out of somethings SOI. Wouldn't the object in question lose just as much energy as it gained falling towards the body as it would traveling out of it's SOI? Educate me please. [link] [comments]  |
| Could a gun be used to propel a spacecraft while it's in space? Posted: 26 Jun 2016 06:18 PM PDT I remember reading that it's possible to shoot a gun in space (they tested shooting a gun in a vacuum on MythBusters as well), and that by doing so you would be propelled back by it. I also remember a thread saying that it's possible to propel yourself in space by throwing a rock. What if a gun, or a ballistics device was mounted to propel a space shuttle? Could it propel it at a fast speed? Would the size of a spacecraft play a part in how fast it could go? [link] [comments]  |
| Would Adding Spin to a Rocket Improve Stability? Posted: 27 Jun 2016 03:19 AM PDT When throwing a football, adding a spin to it seems to improve stability. Would the same be true for for something like a rocket which is much faster and heavier? [link] [comments]  |
| Posted: 26 Jun 2016 07:12 PM PDT I just watched this video and it does a great job explaining how LIGO works, but it begs the question, how do you cancel out the noise from normal Earthly things? A machine that sensitive would be able to measure even the smallest earthquakes anywhere on earth wouldn't it? [link] [comments]  |
| Posted: 27 Jun 2016 02:37 AM PDT I've always been taught that hybrids, such as the mule, are infertile and therefore cannot reproduce. However, I've read that Lemons are a hybrid between a citron and a sour orange (which is itself a hybrid of a pomelo and a mandarin). I also believe there are hybrids between Cannibis species. Is this a strictly plant thing or can some animal hybrids reproduce? [link] [comments]  |
| Posted: 26 Jun 2016 01:54 PM PDT Question was brought up at work, can anyone explain? [link] [comments]  |
| Posted: 26 Jun 2016 05:15 PM PDT My question is similar to asking 'Why do two wires with current flowing in the same direction attract each other, and two wires with current flowing in opposite direction repel?' However, I can somewhat comprehend the reason for this. What I don't understand is how, for example, two positive charges traveling parallel to each other will have a magnetic force that tries to pull them together. [link] [comments]  |
| If rust is just oxidized metal then why can rusty metal transmit tetanus (a bacteria)? Posted: 26 Jun 2016 10:42 AM PDT I've never heard of someone getting tetanus from clean metal so what about rusted metal is different? [link] [comments]  |
