| Are there any reactions more exothermic than nuclear fusion of hydrogen to helium? Posted: 17 Sep 2016 06:24 AM PDT is hydrogen the only element that can be tempted to fuse? [link] [comments]  |

| At what size does a wire mesh stop acting as a Faraday cage? Posted: 16 Sep 2016 06:27 PM PDT Wire meshes can often be used as Faraday cages to shield the inside from exterior electromagnetic waves. At some point, the mesh should stop being a Faraday cage if the holes keep getting bigger. So at what size of mesh does the mesh stop being effective at screening incoming waves? [link] [comments]  |
| What was the weather like on Pangea? Posted: 16 Sep 2016 12:29 PM PDT You'd think there was an extreme version of a land climate there. With warm summers and cold winters. Have there ever been any proof or theories about the climate at the supercontinent? [link] [comments]  |

| Do firearms bullets really become sterilized upon firing? Posted: 16 Sep 2016 10:07 PM PDT A friend told me due to the heat generated by the high velocity and pressure of the firearm, bullets leave the barrel sterilized. Is this true? Is it true of all cartridges? Edit- seems like this belongs in Medicine category, but honestly I am not sure. Let me know if it would be better to move it to a different category.

| Why do some lakes look like a fractal? Posted: 16 Sep 2016 02:34 PM PDT I've seen a couple others like this, but it always stood out to me as looking similar to a mandelbrot. [link] [comments]  |
| How much force would be required to slow the Earth's rotation? What implications could follow? Posted: 17 Sep 2016 08:11 AM PDT a series of massive rocket engines are mounted to the Earth's surface facing East and fired. How much force would slow our rotation? What could happen as a result of slowing rotation? [link] [comments]  |
| what is the definition of the word "cold" in deep space? Posted: 16 Sep 2016 06:30 PM PDT if cold is the slowing of the vibration of atoms and there are only sparse atoms in some areas of space, how is "cold" expressed where there are so few atoms? [link] [comments]  |
| Posted: 17 Sep 2016 07:08 AM PDT Let's say we had a 1000km-thick cereal bowl floating in space. If I started pouring milk onto/into this bowl at any given point (so, not necessarily into the bowl - perhaps on the outer side or bottom), would we be able to determine where the milk would flow? If so, how? My understanding of gravity starts and stops at spherical objects, which is why I'm curious. If we wanted to land a probe on an asteroid shaped like, say, a cereal bowl or a donut, how would we know the best spot to land? [link] [comments]  |
| Is there such a thing as a core of a star? Posted: 16 Sep 2016 03:44 PM PDT I know hydrogen becomes iron, but does that iron amass in the center of the star to eventually cause the star to fail, either in nova or in red dwarf? [link] [comments]  |
| How would Nuclear Propulsion work? Posted: 16 Sep 2016 03:58 PM PDT I want to know how it would work. But most of all, how it could successfully be done without damaging the ship. Also would it be in space or on the ground? [link] [comments]  |
| Could Mars have had a rich, earth-like flora even when we now can't see any hint of it? Posted: 16 Sep 2016 01:21 PM PDT When we talk about life on Mars we usually talk about microbes or other simple and small life forms. I wonder if there could once have been plant life, forests with huge trees without seeing any evidence today. Like, could they have been completey destroyed after Mars lost its atmosphere? So that not a single tree trunk or something like that survived (as a fossil) ouf of billions of trees all around the planet? Because all we see on pictures from our satellites and rovers today is basically wasteland. Or is the lack of any evidence today a strong hint that if there ever was life on mars, it never was much more developed than microbes. [link] [comments]  |

| Do microwaves have an effect on plastic? Posted: 16 Sep 2016 05:55 PM PDT Glass and (some) ceramics are heated by microwaves. Why are plastics not heated the same way? What makes them different? [link] [comments]  |
| Posted: 16 Sep 2016 03:27 PM PDT You can see where it changed colors, really curious why this would've happened. [link] [comments]  |
| Posted: 16 Sep 2016 01:20 PM PDT I have been transitioning to sleeping on the floor this past week and although it is not at all necessary to exclude a folded towel beneath my head I would really prefer not to have to do that. Problem is, as you might expect, trying to fall asleep with your head resting on a hard carpeted floor for thirty minutes results in a progressively more irritating pain at the point of contact the longer I refuse to lift it up. What is going on at that part of my head that causes it to hurt that way? Are there going to be any significant consequences to ignoring it? A callus? Reduced blood-flow to my brain while I sleep? I don't really know, so I'm asking science. [link] [comments]  |
| What is implicit egotism and how much does it really affect our lives? Posted: 16 Sep 2016 04:22 PM PDT I read this article today about how people are drawn to things that are similar to their name. I was wondering how big of a factor it was to our lives. Does it really affect where we live and marry? [link] [comments]  |
| Are there any known weaknesses in the Nielsen Ratings? Posted: 16 Sep 2016 03:19 PM PDT From what I understand they sample cities around the country and estimate viewing based on those samples. Are there any biases or things unconsidered by this method of data collection? I was also curious if perhaps somebody cross referenced data from Netflix viewings. I'm guessing Netflix uses more direct data (i.e. simply how many people streamed this show or movie) and maybe you could compare patterns in viewing of shows or genres by this precise data set and see if there are any interesting discrepancies between the two. The second part makes this a loaded question, but answers on either or would be great! [link] [comments]  |
| In what order does a video load ? Posted: 16 Sep 2016 04:28 PM PDT If I was to play the video after it had loaded the smallest amount of data would it show picture and sound? Just one? [link] [comments]  |
