Why my phones touchscreen sometimes registers a touch when in reality my finger is millemeter or two from screen? Posted: 08 Nov 2018 11:57 PM PST My guess is static electricity since it only happens once in a while and randomly but i am hoping for more insightful explanation. Edit: It also usually happens in the middle of typing. It never happened, for me, on first letters I typed. And, I am sure my finger did not touch the screen in a way i just did not feel it. When it happened i was surely away from screen, that is why it always jumps out when it happens. It is always unexpected. Edit2: I can surely replicate phone registering very soft touches (without me feeling actually touching it) but those random ones I am experiencing are different, the finger is always a lot further away than when i can register a touch without feeling it by testing. A lot may be very relative term but that is how it feels to me, i am not really sure how far the finger actually is because it usually happens really fast and its hard to measure so small distances with feelings. So, there is a small chance that i am imagining it. Edit3: I am using Redmi 5A if that makes any difference. Edit4: I searched my phone but did not find any settings that increase screen sensitivity or glove mode or anything like that. It is an android 1.7.2. submitted by /u/Dreamer_tm [link] [comments]

[Earth Sciences] Is there a current example of a mountain range that is just starting? Posted: 08 Nov 2018 04:07 PM PST I have heard that the Himalayas are young and still growing. And that the Rockies are young and large, while the Appalachians are old and being worn down. Is there a good example of a small mountain range (hills?) in the world that is in the early stages of its development, it has the potential to grow into a full-scale mountain range? submitted by /u/MDCCCLXV [link] [comments]

Augmented reality 7D holograms - how does it make it look like the light stops mid-air? Posted: 09 Nov 2018 02:57 AM PST After discovering this video: https://youtu.be/rD1_C_RAJeE?t=177 I immediately wondered how did they manage to do it? How can the light carrying information about the reference object just stop mid-air? I know it can´t but that´s how it looks like (no pollen, no small particles, no visible gas etc.) and no method of projecting light to create a 3rd object in space seems to apply. Any explanation? I have found out that RIOT (company behind the ceremony from the video) got this marvel from this company https://www.zerodensity.tv/products/reality/ I have tried to google this question and came up with little to nothing - this question https://www.reddit.com/r/askscience/comments/8fjbl9/how_exactly_do_holograms_work_how_does_the_light/ seems related, but I couldn´t find a satisfying explanation. Thank you for your responds! ​ ​ submitted by /u/Teiresias13 [link] [comments]

Is there any "up" direction to the universe? Every map of earth is drawn "right side up", but how do we know that? what measure has everyone been using? Posted: 08 Nov 2018 06:43 PM PST is there any sort of marker of "up" and "down" in the universe? if so, what? submitted by /u/OneEyedCharlie [link] [comments]

Say you know the dirrection the Milky Way is headed and you launch a rocket going towards the dirrection the Galaxy was coming from, from our prospective, would it appear to be going faster than a rocket launched in the same dirrection our galexy is headed to?

If Cacti are known for growing in the harshest of environments, Why don't we see them in non-harsh environments?

What are the consequences of missing a full night of sleep, if you make up for it by sleeping more the next night? Posted: 07 Nov 2018 08:34 AM PST My scientific curiosity about this comes from the fact that I just traveled from the telescopes in the mountains of Chile all the way back to the US and I wasn't able to sleep a wink on any of the flights, perhaps maybe a 30-minute dose-off every now and then. I sit here, having to teach tomorrow, wondering if I should nap now, or just ride it out and get a healthy night's sleep tonight. I'm worried that sleeping now will screw me into not being able to fall asleep tonight. I did some of my own research on it, but I couldn't find much consensus other than "you'll be worse at doing stuff." I don't care if I'm tired throughout today, I'll be fine---I just want to know if missing a single night is actually detrimental to your long-term health. Edit: wow this blew up, thank you all for the great responses! Apologies if I can't respond to everyone, as I've been... well... sleeping. Ha. submitted by /u/djsedna [link] [comments]

How do babies use/learn language? Posted: 08 Nov 2018 07:15 AM PST I've always been fascinated by this: babies who can recognise their mother tongue and separate it from foreign languages they haven't heard often. How do babies start learning a language (and why is it so difficult for adults to learn one), what makes them prefer their mother tongue and how do they interpret what adults are telling them? submitted by /u/YmiXZeno [link] [comments]

Is there a known limit to the amount of horse power an internal combustion engine can produce given set units of air and gasoline? Posted: 08 Nov 2018 04:38 AM PST Obviously if you increase the volume of air and fuel into the engine, the engine will produce more power via forced induction or through increasing the size or number of combustion chambers, but if given a set volume of air and fuel, is there an upper limit to the amount of horse power an engine can produce using real-world physics? I'm hoping there's an answer like "In a 2.5l engine, one gallon of 89 octane gasoline burned per minute cannot produce more than 400hp" I'm specifically thinking about consumer-grade gasoline commonly found at gas stations, not special blends like E85 or racing fuels. submitted by /u/___cats___ [link] [comments]

How long does it take for supplements like calcium or vitamin B to be absorbed? Posted: 07 Nov 2018 06:03 PM PST I want to know how long it takes for a supplement to be absorbed into your body and make a difference in someone's body.

What's the deal with beer bellies? Posted: 07 Nov 2018 05:31 PM PST There's definitely a distinctly round belly that is often associated with drinking lots of beer, but why? ​ I know you can't work out certain parts of your body to target your weight loss, I assume you can't target your weight gain either. ​ Maybe I'm just not very observant, but I don't know if I've ever seen a woman with a beer belly. Is this an exclusively male thing? submitted by /u/BiJa90 [link] [comments]

Is a solar system with breathable air within the interplanetary space possible? Posted: 08 Nov 2018 12:29 AM PST Okay, i watched some 80ies cartoons, and now I have strange questions. Is it possible to have a solar system which has breathable air, not only on planets which can hold an atmosphere, but also in the interplanetary space between them? Could something like that work without the air dispersing, or the whole system getting "too heavy" etc. Any Ideas? submitted by /u/Alexander556 [link] [comments]

Have there been any species once believed to be two distinct species but later proven that one is the juvenile form of another? Posted: 07 Nov 2018 05:17 PM PST I was reading an article about the book "All Yesterdays" and the appendix includes an "All Todays" section where the authors consider how future paleontologists might interpret the fossil record of today. One thing that stood out was that tadpoles might be construed as some sort of fish. Have any species been classified as distinct until advances in science proved that they were different stages of the same animal's life? submitted by /u/GodMonster [link] [comments]

Does a light beam emitted from a laterally moving source have "sideways" movement, or only straight? Posted: 07 Nov 2018 07:02 AM PST I understand that light emitted from a source traveling at n speed (toward the observer) will still move at only c speed (not c + n speed). But how will a light beam act when emitted from a source moving lateral to the [stationary] observer? If I fire a gun from a moving platform, at a stationary target, I have to fire before my sight cross the target, because my lateral movement is imparted to the bullet that leaves the muzzle. But how about a beam of light? Does a lateral moving source add lateral movement to the light? Or does a photon, once emitted, travel in a strictly straight line from its source? submitted by /u/Bullgrit [link] [comments]

In terms of the standing-wave model of electrons, what are chemical bonds? Posted: 07 Nov 2018 05:27 AM PST Title says it all really. I don't really know anything about orbital shapes other than what I've read here, so if they have anything to do with it you may have to walk me through it lol. But I always wondered what caused atoms to bond, is it like constructive superpositions? Or is that a no-no for matter. Edit: in the title I meant electron orbits, not just electrons themselves, though I guess it still kind of works submitted by /u/Mitch_Pinder [link] [comments]

Are atoms considered fluid or solid? Posted: 07 Nov 2018 04:01 AM PST I understand that it depends on the attraction between the atoms to deter main solid and fluid but if you needed to classify a single atoms what would you do? 2bd question, are protons neutrons and electrons solid or fluid. submitted by /u/EnoDevz [link] [comments]

How are extra-galactic gamma rays detected and imaged? Posted: 07 Nov 2018 02:18 AM PST I'm a bachelor student in astrophysics and in one of our classes about detecting and measuring intensities of EM-waves we saw that gammarays are not detectable with optical telescopes because the mirrors would simply absorb the gammafotons. What device or technique is used to form an image? And why can't a CCD-camera be used for such observations? EDIT: I've done some more research and it seems like they use scintilationdetectors. submitted by /u/aHaloGod [link] [comments]

What are the ways heavy elements get created? Posted: 06 Nov 2018 04:37 PM PST I learned that heavy elements are created in stars and distributed through the universe by novas in grade school. Sometime after that I became aware that red giants dissipate with age, and it seems that some of that material must be heavy elements. In the last year or two, I've read about neutron star mergers scattering large amounts of heavy elements. What other ways exist? Do the jets from the galactic black holes also transform the material they eject into heavier elements? submitted by /u/dbtng [link] [comments]
