| Do multiple wounds heal slower than just a single one? Posted: 08 Dec 2015 04:20 AM PST So lets say someone has a single wound like a simple cut or something, would this wound heal in the same amount of time as if the person had like 3 or more wounds yet identical and in other regions of the body?

| Can we naturally exhaust our neurotransmitters? Posted: 08 Dec 2015 05:11 AM PST So as I know it serotonin and dopamine can be exhausted by certain drugs, and as a result we won't feel as good before they were all used up. The rate of the production also has something to do with this I believe. But say if we were to be naturally happy and social and being around someone we love (oxytocin?) all the time could we exhaust these stores and end up having a natural 'crash' where we don't feel as happy social or in love until these transmitters are restored? thanks in advance :) i'm very curious [link] [10 comments]  |
| How do we know that Pi goes on forever? Posted: 07 Dec 2015 07:58 PM PST I was wondering about Pi. How do we know that there is no final end to its decimal places? [link] [35 comments]  |
| Is a nebula visible from within? Posted: 07 Dec 2015 05:30 PM PST Or is it more like a rainbow where it is only visible from a distance? [link] [13 comments]  |

| Is time different at different points on the surface of PSR J1748-2446ad? Posted: 08 Dec 2015 08:30 AM PST Was watching a video about neutron stars recently and the star PSR J1748-2446ad came up with it's rather crazy spin rate (24% the speed of light). Which got me to thinking since speed is determined by distance traveled and time would that not mean that if you could stand on the surface of this pulsar you'd experience time differently if you stood at the equator vs nearer the poles since you'd be traveling at different speeds? If that's the case then does that not mean that the star is ageing at different rates across it's own surface? This may be a nonsensical question but I can't exactly see why. [link] [1 comment]  |
| What is better for the environment, a bidet or toilet paper? Posted: 07 Dec 2015 07:29 PM PST Not necessarily just in terms of carbon footprint, but also water usage. Or other effects I haven't thought of. [link] [8 comments]  |
| What Did Adult Humans Act Like Before Society? Posted: 08 Dec 2015 06:54 AM PST Kids are a view of what humans are like before society constructs them to behave a certain way i.e. tantrums, no regard for various social rules, no concept of money and so on. But what would a developed adult human act like without those constructed ideas integrated into their psyche? [link] [2 comments]  |
| How big is the "shine" of a star when compared to the actual size of the star? Posted: 07 Dec 2015 09:23 PM PST When you look up at the stars, you see them shine a fair amount, but they're not that big. When you look at the sun, it's that big, when compared to its shine. But when you look at a star, is it really as big as the shine it creates? How much smaller is it? Kinda hard to explain what I mean. [link] [4 comments]  |
| Posted: 07 Dec 2015 08:51 AM PST In other words, did scientists already think something was wrong with their theories? Or did they assume measurements were reasonably predicted by those theories? [link] [29 comments]  |
| Why is it that passing a magnet through coils produce an electric current? Posted: 08 Dec 2015 07:06 AM PST I somewhat understand Faraday's law that states a magnet through a coil will produce electricity, but I want to know why? And is magnetic flux simply the passing of the magnet through the coils? How is the electricity made out of nowhere? Just to be clear, I know WHAT happens. I want to know WHY it happens?

| Posted: 08 Dec 2015 07:02 AM PST Thinking about it, it seems like having empty space would allow the liquid to pick up momentum which it disperses when it contacts the other end, while being completely full on the other hand would prevent that kind of movement (would you still have a pressure wave moving through the liquid medium?) It feels kind of counterintuitive though, and I can't help but feel I'm overlooking something. I suppose there are degrees of difference too, which would be interesting to see graphed. A 10% full container would not have to deal with much mass, while a 90%, almost full container would be the worst case(?) - almost the greatest possible mass while still having to deal with empty space. I know there are all kinds of ways you can qualify the question too: What shape of container is it? To what extent is the unfilled portion occupied by gas? I don't want to complicate the question too much. [link] [1 comment]  |
| What's the difference between a Lornez system and chaotic system? Posted: 08 Dec 2015 04:00 AM PST What's the difference between a Lornez system and chaotic system? Are they the same? I think there's some kind of formal mathematical definition or structure for the chaotic system. Is this true? [link] [8 comments]  |
| Posted: 07 Dec 2015 08:02 PM PST I've always understood that expansion occurs everywhere equally, including between the atoms of my body, but was unnoticeable compared to the local forces. [link] [7 comments]  |
| Posted: 07 Dec 2015 06:26 PM PST how about the "anti"-gravity? would it push instead of pull? [link] [23 comments]  |

| Posted: 07 Dec 2015 05:57 PM PST How exactly do symmetries in particle physics, and the breaking of those symmetries, lead to connection fields? Are these fields basically just implementations of the 'rules' that must be followed as a result of a broken symmetry? What exactly IS a broken symmetry, and how is the Higgs field responsible for breaking symmetry in matter? [link] [4 comments]  |
| How can an electron be in more than one place at once? Posted: 07 Dec 2015 08:14 PM PST I was recently watching a debate with Lawrence Krauss and while responding to his opponent he mentioned that an electron can be in more than one place at a time, seemingly defying the laws of physics. I am a freshman in high school, so if at all possible, could I have an explanation of how that works? I probably wont understand it, but if so I appreciate any explanations I can get. Thanks! EDIT: Here is the link and timestamp to when Krauss mentions the electrons-thing. https://www.youtube.com/watch?v=79iPMEG_4i0&feature=iv&src_vid=22cYcsVPOok&annotation_id=annotation_2897502333 Timestamp: 39:55 WARNING: EXTREMELY PROVOCATIVE TITLE, SORRY BUT IT'S NOT MY VIDEO.

| What is the potential output of Wendelstein X-7? Posted: 08 Dec 2015 07:40 AM PST I understand from several places that the focus with this particular reactor is not to achieve efficiency. Are they not planning to get output from the reactor at all, or allow it all to dissipate as heat? I can't seem to find info on that. [link] [2 comments]  |
| Why does Bradford Reagent contain acid? Posted: 08 Dec 2015 07:20 AM PST Working on a lab and I was curious why Bradford Reagent needed to be in an acid. The buffer we use should keep the solution at a regular ph so the protein should keep their shape that way. [link] [1 comment]  |
