| [Neuroscience] Why did we evolve to cry when we're sad? Posted: 14 May 2018 08:42 PM PDT I understand that we evolved to cry to protect our eyes but why do we cry when sad? It doesn't protect us from anything. [link] [comments]  |
| Posted: 14 May 2018 10:00 AM PDT I was thinking about this when I slung a small bag of garbage into a dumpster about 30 feet away. It was misshapen, had uneven weight distribution, and it's not like it's an object I throw regularly, yet I was able to accurately guess how to throw it, and how hard as well. Is there a science behind how our bodies are able to make these calculations on the fly? Is it simple repetition and muscle memory, or is there something more to it? [link] [comments]  |
| What causes infatuation/'a crush'? Posted: 14 May 2018 09:03 AM PDT I understand there might be a number of approaches to a question like this, with a variety of physiological and psychological takes, so I'll give you a little context as to why I'm asking the question to help you clarify things for me. Firstly, I should reaffirm the fact that I am asking this question that has been on my mind for a while with regards to the notion of a 'crush', a social term used by youths (like myself). Secondly, the point is I was wondering if there is a discrepancy (and scientific explanation) between 'romantic' and sexual attraction. More specifically, I want to know if a straight person can have a 'crush' on a member (and only a certain member) of the same sex while still being heterosexual. So, to link back to the titular question, I want to know what physiological and psychological factors influence a 'crush' and if those factors can include things that seem completely unrelated to sexual attraction like simply identifying with them/seeing yourself in them or empathising with them. Sorry if this isn't clear at all, but I would appreciate any helpful responses, even if you can only answer the question from a particular field/point of view. [link] [comments]  |
| Posted: 14 May 2018 11:05 PM PDT Similar to either the two geographical or magnetic poles that Earth has? Do stars in general have poles? If the Sun does have poles, are the orbits of most planets roughly perpendicular to the Sun's polar axis? [link] [comments]  |
| Does the earth expand and contract? Posted: 14 May 2018 08:11 AM PDT OK this may sound dumb but here's my reasoning. I work in construction and one of the common misunderstandings most people have is that everything in their house expands and contracts as the weather changes. This causes a lot of cracks and why there is usually a tolerance with materials. But I was wondering does the earth expand and contract as it revolves the sun since it's not a perfect circle around the sun and gets closer and farther? [link] [comments]  |

| Posted: 15 May 2018 07:42 AM PDT In other words, if the total mass of tumor cells is low, is it less likely that cytokine release will be a problem? [link] [comments]  |

| Why is it dysfunction and not disfunction? Posted: 15 May 2018 12:50 AM PDT And are there any similar examples you can point to that either emulate the reason or alternatively where the reason has ignored and the more common use of "dis" has applied? In my mind they both bean "bad" or "opposite" (e.g. disapprove, disengage etc.) [link] [comments]  |

| How did the moon form, and are there any remnants of earth still present inside of it? Posted: 14 May 2018 05:43 PM PDT How did the moon form after the impact event with the earth? Are there any parts of earth that formed to become part of the moon? And if so, would there possibly be any remnants of it inside the moon that would be recognizable as having come from the earth? For example, could the moon possibly house earth fossils if there was life at the time somewhere deep inside it? [link] [comments]  |
| Can people who have had their corpus callosum severed multitask? Posted: 14 May 2018 08:46 PM PDT Since the two halves of the brain should have no communication with each other, is it theoretically possible for each half to be working on a different task simultaneously? If so, has this been studied and/or documented? [link] [comments]  |
| Posted: 14 May 2018 09:51 PM PDT The quote is taken from this article: https://www.telegraph.co.uk/news/2018/05/14/countries-urged-wipe-killer-trans-fats-foods/ What does it mean to say that 500,000 people die each year from trans-fat? How is such a figure determined? Does it have something to do with life expectancy? [link] [comments]  |

| Does the flow of time have a constant? Posted: 14 May 2018 05:20 PM PDT Maybe I'm not asking the question right but I'll try to clarify. We as humans measure time based on a rotation around the sun (in terms of years, days, hours and seconds). Is there something more fundamental then this? Is there a constant like the speed of light in a vacuum or Planck's Constant for time? [link] [comments]  |
| Posted: 14 May 2018 05:16 PM PDT I.E., if I send a wm_close message repeatedly and it doesn't work, why doesn't Windows automatically run TerminateProcess or whatever it is "end program" does? [link] [comments]  |

| Does sound have an infinite volume? Posted: 14 May 2018 09:39 PM PDT I was listening to some music today and I was wondering why there's a limit to how loud it can be turned up on my phone; this led me to start asking the question: is there a limit to how loud and quiet a sound can be?
