How are the standards for sufficient Vitamin/Mineral concentration in humans fixed? Posted: 14 Apr 2019 07:40 AM PDT I recently read an article about the debate on standard for sufficient Vitamin D levels, and 2 groups come up with distinct ratings for the normal levels. With standard statistical techniques shouldn't there be no disagreement about these things? (like mean in a population?). But say we got the population means for 2 different geographical areas, or maybe 2 different ethnic groups, then there is a chance they might be different. So how can we tell if this difference indicates a deficiency ( or conversely overconcentration) in one, or it is just characteristic for that group? submitted by /u/ibsdatascientist [link] [comments]

Do blind people have more trouble creating a stable sleep/wake rhythm? Posted: 14 Apr 2019 07:36 AM PDT Hi r/askscience, I am a student Biomedical Sciences with a very (in my opinion too) small background in neurosciences. I know that people become sleepy because melatonin gets released at certain times through the biological circadian rhythm and due to a lack of light that hits the eye. Knowing that the presence of light heavily influences the melatonin release and knowing that the human rhythm is approx 24,5h, I was wondering whether blind people have more trouble acquiring a 'regular' circadian rhythm when compared to a person that can see properly. Cheers! Edit: please forgive me for any spelling or grammatical errors. I am on mobile and English is not my first language. submitted by /u/Wiebehd [link] [comments]

How does interaction with a Higgs Boson particle indicate mass? Posted: 14 Apr 2019 05:19 AM PDT Title really. I think I'm conceptualising this correctly, and it says that a particles mass depends on how much it interacts with a Higgs Boson, like a top quark has a high mass because it interacts with it a lot, but a photon doesn't interact at all, so it has no mass. So how does interaction with the Higgs field or the Higgs Boson particles indicate mass? Thanks. submitted by /u/OhhFluxy [link] [comments]

Is LIDAR light visible to any known animal species? Posted: 13 Apr 2019 09:55 AM PDT The more common this technology becomes, the more likely it is that urban and suburban environments will be awash with the light from these systems. Extensive research has been performed on radio frequency sensitivity within nature, as well as the effects of acoustic sensors in marine environments, however I have yet to see any research discussing/exploring this topic of LASER within nature.

Birth control stats, how are they measured? Posted: 13 Apr 2019 04:56 AM PDT I work part time in an ob/gyn clinic and it seems like the most effective method has like 1/2000 chance of getting pregnant. So if a person (female) had sex 2000 times (mind you I'm a redditor, so I'll be lucky to get there in a lifetime, so this person won't be me) chances are they would end up pregnant. I guess I'm just not sure how these stats come about and what they mean. And they are not super reassuring to me. I also assume the companies also don't want to say their method is 100% effective as well. And I've seen a few IUDs inserted incorrectly so human error is also a concern. submitted by /u/cheaganvegan [link] [comments]

How old is the snow on top of Mt Everest? Posted: 12 Apr 2019 11:24 AM PDT Saw an r/Showerthoughts post earlier that talked about the snow on top of Mt Everest. This got me thinking about the lifespan of snow. Living where I do, the Pacific North West, I think of snow as a fleeting thing, tied to a season. Lasting a few days at most. I think of how delicate snowflakes seem and imagine they can't last too long out in the wild. But then this... Somewhere relatively undisturbed with weather conditions that suit, how long can a snowflake last? Does it just remain in that form indefinitely? Is there any way at all to tell how old snow is? submitted by /u/pjclarke [link] [comments]

Has Earth had a bigger mountain than Mount Everest?

During pair production does the photon just split into a particle and antiparticle or is the photon fired at something?

How Responsible is the Decay of Radioactive Elements for the Brightness of a Supernova? Posted: 12 Apr 2019 03:02 PM PDT It always seemed really clear that supernovas were bright because they were so hot and energetic, (releasing as they do more power in a few minutes as the sun will in its whole life.) However, I recently read (in "The Magic Furnace" by Marcus Chown) that this might not be the whole story. In the 1930s, a supernova in Galaxy IC4812 was observed whose brightness cut in half every 55 days, similar to the pattern of a radioactive element with a half-life of 55 days. This led Geoffrey Burbidge to suggest that the fade of this supernovas brightness was due to the presence of recently created californium-254 (which has a 60 day half-life) decaying in the expanding shell of shock-wave. (This was apparently later corrected and while the general idea is claimed to be correct, now scientists believe that the decaying light owes more to radioactive nickel-56 (half life of 6 days) and cobalt-56 (half life of 77 days) created during the supernova mimicking a single isotope with a half life of 60 days.) My question is, how much of a supernova's brightness comes from traditional, 'I'd expect this from a giant explosion' sources, like heat from compression, friction, etc, and how much comes from this radioactive decay?

The Voyager pulsar map not only marks where the Earth is located, but when the Voyager probe was launched. How did we calculate this? Posted: 12 Apr 2019 09:01 AM PDT Pulsars make fantastic beacons because they are incredibly reliable on their pulse timing and because they can be markers not only for where in the universe something is but also when it was there. The Voyager pulsar map shows where Earth was located when the probe was launched, but how did we calculate this? I would assume that at the time you could easily look at where the Earth is in relation to the pulsars at that moment* and just use that, but what if I wanted to make a map like that for a time long ago or long in the future? *Did the designers of the map actually have to do more calculations than I'm postulating because the time delay in light travel skewing the relational positions? Or did they just wing it and say "that's where we see the pulsars are in relation to us factoring in delayed light, the aliens can figure that out"? Disclosure: while I am actually very interested in hearing the answer to this, I have to admit I also have the selfish intentions of getting a Voyager pulsar map tattoo that shows where the Earth was in both time and space on my birthday. submitted by /u/lemcott [link] [comments]

How big does a meteor need to become a meteorite? Posted: 12 Apr 2019 12:35 PM PDT So my question is this, how big does a meteor need to be to be able to survive the transfer from outer space through our atmosphere and impact earth to the point its of notable size like the Gibeon landfall? I understand the make up of said meteor would make a difference in its resistance to breaking down as it burns through the atmosphere. submitted by /u/Subliminal_Image [link] [comments]

Information in Regards to the Pāli Language? Posted: 12 Apr 2019 12:34 PM PDT Hello members of Askscience! I have a few questions about the ancient Pāli Language that I just can't seem to find any good resources which touch on them. I understand very little about this language. I know as much that it's the liturgical language of Theravada Buddhism, but I do not know much about it in terms of historical relevance and Linguistics. I am looking for any information regarding the Pāli Language but most specifically: What people groups or civilizations used the Pāli language? Either as their mother tongue or a lingua franca. How many speakers do we estimate spoke this language at its height? Why did it die off as a spoken language? What is the closest modern language that we can see influences in? What linguistic features or rules of this language make it unique? E.G. Arabic (and other languages) utilize an Abjad writing system. Any information regarding the Pāli Language is greatly appreciated, but it might be easier to compare it to other ancient languages of the time. I imagine Sanskrit and Pāli share many features and vocabulary, but this could be a sign of my lack of knowledge. submitted by /u/grumpygator123 [link] [comments]

Is there any singularity-free gravitational soliton? That is, is there an asymptotically (but not thoroughly) flat, static, nonsingular vacuum solution of General Relativity? Posted: 12 Apr 2019 12:10 PM PDT I've heard that if you replace "static" with "spherically symmetric" in the above question and ignore "singularity-free", then by Birkhoff's theorem the only such spacetime is Schwarzschild. I wonder is there a similar theorem/result that says the following: "the only static, asymptotically flat, (non-coordinate-)singularity-free metric is Minkowski flat space"? submitted by /u/Laroel [link] [comments]

Does water dry quicker depending on temperature? Posted: 12 Apr 2019 05:17 PM PDT For example say I spilt hot water on a jumper and cold water on another jumper which one would dry faster?

How CRT TV controls the beams so quickly back in the old days? Posted: 12 Apr 2019 03:02 AM PDT Unlike LED where each pixel has a light source, a CRT relies on just 1 set of cathode ray tube (for color tvs that has 3 color beams). I understand the control of the beam directions done by a set of magnetic coils, however even for very old B&W TV's, it would still require not just precision but super human speed to point the light at the correct spots. To do so with a modern circuit would be easy, but how did they achieve such speed & accuracy back then when even electronic calculators did not exist? ​ also any reason no manufacturer tried to use more sets of cathode ray for higher resolution and faster refresh rate? submitted by /u/burningbun [link] [comments]

Why is M-Theory incompatible with the E-8 lattice? Posted: 12 Apr 2019 01:09 AM PDT As far as I understand M-Theory, it's the best existing extrapolation of String Theory, bringing together all other exclusive string theories. I recently heard about the E-8 lattice and find it to be an elegant solution to the question of everything, but it surprises me that it's considered completely incomparable with string theory. Is it just the maths, or is there something more fundamentally incompatible between the two theories of everything? edit: sp submitted by /u/ZeF_TyM [link] [comments]

Are some languages more difficult for people with dyslexia? Posted: 11 Apr 2019 11:51 PM PDT I don't have dyslexia. But I know it is something like seeing letters not as we see them, or at least mixing them up. Now I was wondering if it's more difficult in other writings, for example Asian languages or Arabic? Because for me those characters seem more complex than our alphabet. For example, is Chinese as a native language also more difficult for Chinese speaking people with dyslexia? submitted by /u/KristofDSa [link] [comments]

What happens to the blood vessels going to the hand if you lose the hand? Posted: 11 Apr 2019 01:08 PM PDT If your hand is removed, there should still be blood vessels in the wrist that used to go into the hand.
