Why do some animals lay brightly-colored eggs? Posted: 30 Apr 2017 06:10 PM PDT This thread confused me. Wouldn't brightly-colored eggs be easier for predators to see? I understand that evolution doesn't act with intention, but I'd think those animals with more naturally-camouflaged eggs would find theirs eaten less often. submitted by /u/stereotype_novelty [link] [comments]

Is it possible to build an air conditioner that stores the heat instead of simply moving it somewhere else? Posted: 30 Apr 2017 07:07 PM PDT I'm wondering if this device is at least theoretically possible, or if it even already exists. The general idea is that you could put this device in the center of a room and it would cool the air while somehow storing the heat inside. I'm assuming that it would need to be powered outside of just the energy in the room, but I wasn't sure if the thermodynamics would work out even at maximum efficiency. What do you guys think? Or, Where better could I ask this question if you guys aren't the right place? submitted by /u/brennie42 [link] [comments]

Why is the ipso carbon shielded in bromobenzene? Posted: 30 Apr 2017 12:50 PM PDT Why is that the ipso carbon is the most shielded, or upfield, of all the carbon atoms in bromobenzene? Given its proximity to an electron-withdrawing substituent like bromine, wouldn't it be deshielded? submitted by /u/orange_you_citrus [link] [comments]

How does blindness affect body language? Posted: 30 Apr 2017 03:03 PM PDT Obviously, body language is not perceived by blind people, but what are the differences in the body language exhibited by them and visually unimpaired people? submitted by /u/CharlesDanceWDragons [link] [comments]

What is a prism and how is it different from regular glass? Posted: 01 May 2017 02:33 AM PDT I've been looking for this answer for a long time but I can't find an answer. I usually see something like "It's a special type of glass" which is utterly unhelpful. Is it the shape? The chemical composition? submitted by /u/JasontheFuzz [link] [comments]

Will UK, American and Australian English eventually diverge into different languages? If so, how long will it take? Posted: 30 Apr 2017 03:52 PM PDT When I hear old radio or TV broadcasts of American English or Australian English, it seems to me to be much more British sounding than today. Part of that could be that broadcasters use a sort of sanitized version of the language so that everyone can understand. But still, I think there has been a noticeable shift in just the last 50-100 years towards diverging. It's happened in the past with languages like Spanish, Portuguese and Italian, or Dutch and Afrikaans, and many Arabic and Chinese languages. And surely dozens or hundreds more languages I can't think of. The obvious point now is that we are a globalized society largely thanks to the internet. So that will likely slow (or completely halt?) the evolution of the different English dialects, and we don't really have a historical precedent to know how that will affect language evolution. Any linguistics experts here to chime in? submitted by /u/alien_clown_ninja [link] [comments]

How do manufacturers of voltmeters achieve (ideally) infinite resistance? Posted: 30 Apr 2017 08:37 PM PDT I understand why this is done -- so that the voltage being measured isn't affected by the voltmeter itself, but I'm curious as to how exactly one can achieve close to infinite resistance. Studying for my Physics 1 AP this week, and figured I would ask this question because I thought the idea of "infinite resistance" or close to infinite was really interesting and if anyone knows how this is accomplished, it would be awesome to know. thanks! submitted by /u/sourpatchkid425 [link] [comments]

When discharging an inductor, does it also create another opposing voltage? Posted: 30 Apr 2017 11:46 PM PDT Upon charging an inductor, it creates an opposing voltage that decreases in time until it no longer produces an opposing voltage. When discharging an inductor, since the current is decreasing with time, does it also create ANOTHER voltage opposing that decreasing current? submitted by /u/yosimba2000 [link] [comments]

Does atmospheric pressure affect your vision? Posted: 30 Apr 2017 09:52 AM PDT I have astigmatism, and I've noticed that when I'm at lower altitude my eyes get tired less frequently. I've also noticed on days when there is high pressure outside, my eyes get less tired. submitted by /u/jbduryea [link] [comments]

What colour would a neutron star be? Posted: 29 Apr 2017 04:15 PM PDT A neutron star is made up nearly entirely of neutrons, sometimes called Neutronium, so there are basically no electrons at all in the outside of it. Because this is the case, how would light react with it? Would the neutron star be like a mirror of sorts? Completely white? submitted by /u/conalfisher [link] [comments]

Why do planets further from the sun receive less energy from its light? How does 'empty' space diminish this energy? Posted: 29 Apr 2017 02:08 PM PDT I was researching the factors that influence the surface temperature of planets and I was expecting to find that atmosphere composition (greenhouse gases and what not, Venus as an example) was the main factor, but it turns out the most important one was distance from the sun. How can light traveling through 'empty' space lose energy? submitted by /u/updateMotivation [link] [comments]

Why is it critical to have extremely accurate time, for Electricity distribution networks to function? Posted: 30 Apr 2017 06:18 AM PDT I over heard a couple of Engineers at an Electrical power plant discuss the importance of having extremely accurate time through atomic clocks (something like 1 second of error over 3,000 years is minimum acceptable). Hoping some one could explain, exactly why such time accuracy is required, what does it enable? submitted by /u/din-din-dano-dano [link] [comments]

How did scientists explain the formation of heavy elements (particularly elements heavier than iron) before supernovae nucleosynthesis? Posted: 30 Apr 2017 03:54 AM PDT Surely there must have been some explanation for formation of metals like gold and silver before the phenomenon of exploding stars was discovered or even suggested? submitted by /u/boogle93 [link] [comments]

Will I get charged plates if I cut a capacitor in half? Posted: 29 Apr 2017 12:06 PM PDT Say I charge a capacitor, then immediately remove it from the circuit. Now, there is no path between the two plates of the capacitor, so if I cut it in half, will I get one plate that is positively charged and another that is negatively charged? submitted by /u/yosimba2000 [link] [comments]

What field of physics does the ER=EPR conjecture fall under? Posted: 29 Apr 2017 02:49 PM PDT As no department at my local university seems to believe that it is in their area of expertise. submitted by /u/KuusamoWolf [link] [comments]

Is there a unified Geiger Meter data set? Posted: 29 Apr 2017 02:30 PM PDT Most schools in the world don't have reliable access to a Geiger Meter or radioactive samples to measure, making lab experiments in physics class difficult to carry out. I want to build an open source program which will help simulate a Geiger Meter for classrooms. For that, I am looking for a unified dataset, or a formula which might help me extrapolate (simulate) the readings for different radioactive materials. For example, something in the lines of: If you hold 1 gram of radium 1cm away from a Geiger Meter, you get XYZ reading. Most sources I found are either about radiation on a global scale: https://api.safecast.org/en-US/measurements or theoretically describe what the readings would be... https://en.wikipedia.org/wiki/Geiger%E2%80%93M%C3%BCller_tube#/media/File:Detector_regions.gif I was thinking of pairing it with an easy DIY ionization chamber radon detector: http://www.techlib.com/science/ionchamber.htm submitted by /u/sanzensekai [link] [comments]

Why is there no "electron radiation"? Posted: 29 Apr 2017 03:13 PM PDT As I understand it, there is radiation that is made of particles (protons/neutrons/neutrinos(?)). But I have never heard of a radiation that would be made of electrons. There is probably an obivous reason for that, but I can not see it (yes, I tried google). submitted by /u/neuromat0n [link] [comments]

Why can't you explicitly calculate the schrodinger equation in computational programs like Gaussian? Posted: 29 Apr 2017 05:15 PM PDT I've been studying computational chemistry for awhile now but I'm perplexed by some of the theoretical aspects of comp chem. Mostly why it's easier to approximate a wavefunction for atoms with many Gaussian distribution functions rather than solving the schrodinger equation outright? Does this have to do with the many-body problem in quantum mechanics? If so, why is it not possible to describe the wavefunctions for big atoms? I know a full CI is the closest you can get to solving it outright but I don't understand how it works mathematically. submitted by /u/cinnabarbun [link] [comments]

If quantum particles only collapse from a superposition of wave functions when they are observed, what are the requirements to count as an "observer"? Can quantum particles observe themselves or other particles? Posted: 29 Apr 2017 08:57 AM PDT Let me start by saying I am beyond completely unqualified for this kind of stuff, but this question arose from a strange night when I was alone in my apartment. I was wondering if I am made out of quanta at some level and everything else is made out of quanta, then the question really is why does everything not seem to behave by quantum mechanics above a certain size? I knew that these particles behaved less strangely once they were observed and they collapsed, and I wondered if I was just a single, unobserved quantum particle, what would I see? Would I be in superposition or would I have collapsed into a single function? What about the particles around me? What would this imply about what I observe everyday in "normal" matter? I guess the above nonsense is the essence of my actual question, I don't have any of the education in physics to even begin answering my own questions, or even where to look, so I was hoping someone here might have some insight. Thanks in advance! submitted by /u/Absle [link] [comments]

how does twitter spam removal work? Posted: 29 Apr 2017 04:47 PM PDT So usually when I enter to see what's on twitter's hashtags in the U.S. they are relatively spam free. However, when looking at hashtags from my country I see a huge amount of spam. I think that twitter has bots that delete spam, so I was wondering why they don't function as well in other languages. Is it just that there are more people spam bots in my country or does twitter spam detection work that much better in English? submitted by /u/hello_ABC [link] [comments]

If time is dependent on speed, what is the reference point? Posted: 29 Apr 2017 01:01 PM PDT If you move faster it is shown that time is passing slower.

Are ergodic processes always stationary? Posted: 29 Apr 2017 02:57 AM PDT If a process is ergodic does that necessarily entail that it cannot change over time? Asking in relation to Friston's Free Energy framework that assumes living systems are ergodic, but a question has been raised that ergodic processes are necessarily stationary, and living systems are not stationary, so they cannot be ergodic. However I have read about specifically 'stationary ergodic processes', which implies that not all ergodic processes are stationary. Any clarification greatly appreciated. Thank you. submitted by /u/Paranoid4ndroid [link] [comments]

I bought pollen free sunflowers seeds by accident. But how did the seller create these seeds in the first place? Posted: 28 Apr 2017 02:30 PM PDT My Google fu has failed me! Quote from a seller of pollen-free sunflowers: " We actually develop all of the sunflower varieties that we sell by conventional plant breeding. No genetic engineering, no GMO. It's a long process that takes at least 7 years from start to finish before we can produce the seeds." Okay, cool. "The fact that our varieties are pollen free means that they cannot pollinate themselves and therefore will not breed true from any seeds that you might find in heads after flowering." So how can they get pure-bred sunflower seeds when the breed cannot create pollen, thus cannot be fertile, thus cannot create seeds? Even if it was GMO, how do you get the engineered plant, how do you get that one to produce fertile, non-hybrid seeds? submitted by /u/IrisHopp [link] [comments]

The 'Oh My God Particle' was estimated to have a kinetic energy of about 48 Joules. What would it feel like to be hit by this atomic nuclei? Posted: 28 Apr 2017 09:42 AM PDT Here is the link to to the PBS Spacetime video on youtube explaining the 'Oh My God Particle' and other cosmic rays: The Oh My God Particle Quoted energy is at about 1 minute.   In the video he equates it to a "good size stone thrown at your head at 50 miles per hour." I assume the particle would pass through me 99.9% of the time unobstructed. But if my body were to stop it, would I even feel it? What would it feel like? Could it damage internal organs?   Thanks for any insight! submitted by /u/idontknowdogs [link] [comments]

How do processors (Qualcom) have an effect on charging speeds? (Quickcharge) Posted: 28 Apr 2017 03:32 PM PDT I cannot wrap my head around this. How does a processor dictate how fast a charger can charge? For example, Quickcharge 4.0 needs a Snapdragon 835 processor or higher. From a novice Computer Engineer standpoint, I can understand circuits and battery dictating charge speed but not the processor. submitted by /u/DefinitelyNotHomeles [link] [comments]

Why do handheld glass magnifiers get smaller as the strength of the magnification increases? Posted: 28 Apr 2017 11:32 PM PDT I work with seniors and individuals with low vision. We show them various types of magnifiers and how to use them to be independent. I have the hardest time explaining to them that getting a larger strength handheld glass magnifier means that the circumference will be smaller not larger. I would like to understand this better so I am clear and correct when explaining to others. I say handheld glass to differentiate between a glass magnifier set in plastic and video magnifiers that can magnify multiple times using video imaging. submitted by /u/WanderDrift [link] [comments]

What makes water so significant for searching for potential life? Posted: 28 Apr 2017 09:32 AM PDT I've been watching a lot of videos on YouTube about the Drake equation, potentially habitable planets, planets with potential life, etc. and I got to wondering why is water so significant to a planet potentially having life? Is it just because of our observations of biological life on earth? Is it not plausible that there could be life forms that can live off of other elements or gasses like CO2? I'm not super familiar with this kind of science, as I am a software engineer, so I apologize if this question is redundant. submitted by /u/chrisrod369 [link] [comments]
