Do we innately conceal our genitals? Posted: 29 Jun 2018 01:27 AM PDT Clothing seems to cover the genitals across all cultures. Reading on Wikipedia, it seems that covering the genitals began at most 72,000 years ago, as remains have been found with clothing from that time. But for all of recorded history across all cultures that recorded history, clothing that covered at least the genitals was considered natural and normal for everyday life. Glorious Wikipedia claims, in the article history of nudity, that nudity was the norm in "warmer climates" until the introduction of Islam or Christianity. It claims that nudity is still the norm in "Mursi, Surma, Nuba, Karimojong, Kirdi, Dinka and sometimes Maasai people in Africa, as well as Matses, Yanomami, Suruwaha, Xingu, Matis and Galdu people in South America". Upon further examination all of these claims are sourced to Active Naturists, "what if nudity were a norm?" (sic), a nudist blog post scholarly journal, surely. I'm sure it's a great source, since it's cited on Wikipedia and all, but it seems to stake its claims that nudity was the norm among those peoples on questionable grounds: Artwork and statuary, mostly from the ancient Greeks, who notably liked naked young guys and also are not any of the people listed Photos of African boys/men during nude initiation rites Quotes from noted racist Henry Morton Stanley about the clothing habits of "the naked savages" during appeals to the British to claim African colonies and convert the natives "to the wearing of clothes" Photos of nude Nuba men presented with scarcely believable context; perhaps that is their everyday habit, but other sources suggest that the nudity is related to traditional Nuba wrestling Some photos of Amazon native people presented with extremely questionable context Various other photos of native African and Amazonian people, which Active Naturalist gives me no reason to believe are typical A ton of photos of native African and Amazonian people who are clothed in their genital region, but presented as if they are nude Any further Googling just gets me shitty pop-psych articles like "if we were nude guys would be horny all day duh". Are there any human cultures where the genitals would be exposed in daily activities? Do we know why we prefer covering our genitals? submitted by /u/Xelif [link] [comments]

Did Paleolithic diets lead the human jaw and face to develop a different shape? Posted: 29 Jun 2018 05:59 AM PDT According to Wiki, "After the advent of agriculture over 10,000 years ago, soft human diets became the norm, including carbohydrate and high energy foods. Such diets typically result in jaws growing with less forward growth than our paleolithic ancestors and not enough room for the wisdom teeth." submitted by /u/icydepth [link] [comments]

Why does nitrogen break the octet rule in NO, while oxygen do not? Posted: 28 Jun 2018 01:44 PM PDT So NO has 11 valence electrons. The oxygen fills up all 8 of its electrons, while nitrogen gets the radical. Why doesn't oxygen get the radical and nitrogen with 8 e-. I get that it breaks the octect rule because it has a odd number of valence electrons. submitted by /u/TheNamesGrant [link] [comments]

Which substances or foods create metabolites that can be detected for extended periods of time? Posted: 28 Jun 2018 08:38 AM PDT I was recently reading about alcohol and how even after your body has completely processed and excreted the ethanol, it creates metabolites Ethyl Palmitate and Ethyl Glucuronide that can be detected in hair for up to 90 days. I am curious as to why these metabolites hang around for so long and also which other substances and/or foods have metabolites that can also be detected for any extended period of time. For example, if I consumed caffeine how long would you theoretically be able to test for it if you wanted to? What about broccoli, or carrots etc? Are there any factors that cause metabolites to stick around longer, or certain groups of foods? I hope my question was clear enough and not too broad scoped. Thanks! submitted by /u/metabolitesarecool [link] [comments]

Do snakes live together? (Garter snakes) Posted: 28 Jun 2018 04:54 PM PDT There is a rock near my house with a hole in it and everyday I walk by and there are 2-3 snakes living together in the hole. It seems like they're friends or a family or something. The biggest snake stays at the exit, male garter snake, then when I approach if I get too close he will slither out and run off. Then when you look inside there is at least one other snake that appears to be female. Do snakes live together and are they really smart enough to devise this survival strategy? Is this common? submitted by /u/jesusd2 [link] [comments]

Why is there much more of certain elements compared to the elements next to them on the periodic table? Posted: 28 Jun 2018 09:39 AM PDT My basic understanding of how elements are formed is that the heavier the element, the more energy is needed to create the conditions for it to be formed. So I would expect the occurance of elements to be pretty much descending the heavier the element is. But, looking at the webpage sourced below for the universes makeup, that's not so. For example, there's a lot more carbon than boron, much more oxygen than fluorine, and much more iron than maganese or cobalt.

Can multiple parallel procedures be simulated as a one? Posted: 28 Jun 2018 10:41 PM PDT If you have an abstract system which runs a number procedures, naturally with possibility of being out of sync, is it possible to emulate the evolution of the whole as a single procedure. I just go idea that one could maybe encode the whole system as an evolution of one-dimensional string. Or does it turn out fundamentally impossible task?

Does caffeine actually increase the production of dopamine, or does it just enhance the dopamine already in your system? Posted: 27 Jun 2018 06:38 PM PDT I was casually drinking my coffee and wondering what this is actually doing to my brain and why I feel so great when I drink it. Sure enough, it's partially because of dopamine. Here's why I am confused, though. Does the brain start producing more dopamine, or does it just take longer for it to be reabsorbed, or both? A lot of articles I read mention how it lets the dopamine "do it's thing more freely", but I'm not sure if that means ramp up production, or just act differently than before. submitted by /u/FungoGolf [link] [comments]

How does the mechanism for 'locking' something by pressing it into a slot and 'unlocking' by pressing back down work on devices like a nintendo ds? Posted: 27 Jun 2018 08:00 PM PDT Similarly to how clicking a pen works, my Nintendo DS accepts cartridges once they're pressed down a certain distance and it clicks into place. When I want the cartridge released I press back down and it releases the cartridge. How does this mechanism work? Is there an image I can look at? I was cleaning out my closet and I came across my old DS and realized that I have no idea how that mechanism functions. I never questioned it as a kid but now the question has been gnawing at me and I couldn't find an answer online so I've made this post submitted by /u/Lazy_Lifeguard [link] [comments]

Does the edge of the observable universe sway with our orbit around the sun? Posted: 28 Jun 2018 03:47 AM PDT Basically as we orbit the sun, does the edge of the observable universe sway with us? I know it would be a ridiculously, ludicrously, insignificantly small sway, but it stands to reason that maybe if you were on pluto, the edge of your own personal observable universe would shift no?

What is dirt made of? Is there a standard set of dirt ingredients that make it dirt, or does dirt/soil/the soft ground stuff vary entirely by location?

How can we measure the age of the universe if time is relative? Posted: 27 Jun 2018 12:13 PM PDT How do scientists reckon the universe is 13.8 billion earth years old if time is relative, and the nature of time would (in my understanding) have been of variable nature?

Why did black holes get rejected as the reason behind the rate of rotation of the milky way? Posted: 27 Jun 2018 10:10 AM PDT I am currently reading the (illustrated) "brief history of time" by Steven Hawking. As stated in the Foreword most of the book remained similar to the original version from 1988. In the chapter about black holes Hawking states that there are probably way more black holes in the milky way than visible stars which would explain why our galaxy rotates at the rate it does. As far as I know the most accepted explanation of today is that the extra mass needed is provided by dark matter/dark energy. Therefore I assume that this understanding changed between 1988 and today. Why? submitted by /u/HerrZog103 [link] [comments]

If black holes slowly lose mass from Hawking radiation, why don't they become neutron stars?

Is there a concise way of describing the degree to which a material can be "packed down?" Posted: 26 Jun 2018 05:36 PM PDT This question came into my head while making a cup of coffee (or 5) this morning. I am used to measuring out whole bean coffee but only had ground available, and wasn't sure how to convert. The obvious non-answer is "it depends on how well the ground coffee is packed," which got me to thinking "why does it seem to not also depend on how well the whole bean coffee is packed?" Now I find myself wondering if this property has been well studied (it seems like it must be, I'm sure it comes up in things like civil engineering) and if there is a neat way to describe it. It seems like there is a geometric question about the shape of the "particles" for wont of a better word, but maybe also a physical one regarding the size and malleability of the particles. For example it seems at a cursory glance like fine particles may be easier to pack down than coarse ones. If anyone has come across this idea or has some insight into what properties of a material would affect it, I'd be grateful to hear! submitted by /u/lemonp-p [link] [comments]

Sorry for the dumb question! How does feeling a breeze when moving not violate Special Relativity? Posted: 26 Jun 2018 07:31 PM PDT Sorry if the question seems dumb, but I was doing some reading on Special Relativity and the Principle of Relativity and it got me thinking: If I were moving at a constant speed in a car, for example, and I stuck my hand out the window, I would feel a breeze. The fact that I feel a breeze tells me I'm moving. Doesn't this violate the Principle of Relativity and how a reference frame at rest should be no different from a frame at constant motion? If I was at rest in the car, I wouldn't feel a breeze but if I'm moving, I would. Obviously, there's a flaw in my logic but I can't figure out where. Thanks for the help! submitted by /u/Blueking71 [link] [comments]

Does distance from the center of a galaxy affect the average make up of stars? Posted: 26 Jun 2018 02:07 PM PDT For example, do larger stars tend to occur closer to the center and smaller stars further out?

Don't excited electrons give off the same wavelength they absorbed earlier, effectively cancelling out the effect on colour? Posted: 26 Jun 2018 01:50 PM PDT When white light is shined on a pigment, some electron gets excited on a higher energy level with a certain fixed energy difference which corresponds to a colour. White light minus the absorbed colour is the complementary colour.
