Where sensors and analysis measure global temperature? Posted: 12 May 2016 12:03 AM PDT I'm imagining a network of weather stations with air temperature sensors. My detailed question is, whenever I see a large graph of temp data displaying global warming, what are the sources? Are there probes located in the oceans as well as continents? What numerical formula is used to combine the temp readings into a global average? What uncertainty factors are taken into account? Because I feel powerless to do anything about it, I'm one of those people who doesn't care a whole lot about global temperature changes. However, I'm very interested in the evidence of whether or not it is occurring. I want to know the nuts and bolts of the data so I can definitively talk to people about the state of our atmosphere. PS. I categorized this as "Engineering" because the answer I want has to do with sensors and analysis... and none of the other topics seemed to fit. Maybe Earth Science? Meteorology (not listed) would probably fit best. submitted by /u/scurvybill [link] [comments]

Is √-1 the only imaginary number? Posted: 11 May 2016 06:12 PM PDT So in the number theory we learned in middle school, there's natural numbers, whole numbers, real numbers, integers, whole numbers, imaginary numbers, rational numbers, and irrational numbers. With imaginary numbers, we're told that i is a variable and represents √-1. But with number theory, usually there's multiple examples of each kind of number. We're given a Venn diagram something like this with examples in each section. Like e, π, and √2 are examples of irrational numbers. But there's no other kind of imaginary number other than i, and i is always √-1. So what's going on? Is i the only imaginary number just like how π and e are the only transcendental numbers? submitted by /u/ButtsexEurope [link] [comments]

What's on the other side of a belly button? Posted: 11 May 2016 11:46 AM PDT submitted by /u/Kaiyedy [link] [comments]

When dropping a phone, can the case breaking off absorb some of the shock? Posted: 11 May 2016 04:57 PM PDT I noticed that every time I drop my phone at all the back of the shell pops off. Inconvenient, but I started wondering if it'd be any worse if I attached the shell better. submitted by /u/VectorLightning [link] [comments]

Krebs Cycle: Where does the extra oxygen come from in the oxaloacetase+Acetyl CoA-->Citrate step? Posted: 11 May 2016 07:43 PM PDT I am in a high school biology class, and I was studying the krebs cycle specifically tracing the oxygen through the cycle; in my textbook the diagram shows acetyl coA donating one oxygen to Oxaloacetate, which already has five, and then becoming Citrate, which has 7. Where is this mystery extra oxygen coming from? What am I missing? submitted by /u/kit_hairington [link] [comments]

Do animals avoid incest when mating in the wild? Posted: 11 May 2016 09:06 AM PDT Moreover, do animals remember or recognize their siblings and then avoid mating with them in the wild? submitted by /u/Skylordjovis [link] [comments]

In the double slit experiment, what are the results if you remove the slits? Does the wave pattern still appear? Posted: 11 May 2016 07:30 AM PDT submitted by /u/JustAnotherBot1655 [link] [comments]

Why is gas under pressure cold? Posted: 11 May 2016 06:57 AM PDT This might be a stupid question and I still haven't figured this out.. So obviously stars are made of gas etc. My extremely basic understanding is that they're really hot because they're under extreme pressure. Why is compressed gas in e.g. cannisters or lighters cold? EDIT: Thank you everyone for your answers, it's actually pretty interesting. submitted by /u/CuntOnABike [link] [comments]

Do animals seek a variety in their diet? Posted: 11 May 2016 09:36 AM PDT For animals, why are feeding chains organised into food webs, rather than chains, is it because having more than one source of nutrition provides a security in the case of an extinction occurring to a species you're feeding on, or do they simply enjoy having a variety in their diet, much like the way we humans do? submitted by /u/theLAZYmd [link] [comments]

Why can't I charge my bigger devices using USB? Posted: 11 May 2016 09:10 AM PDT I know that with some devices, when plugged into USB and in use, the battery will be depleted faster than it can be charged - but why are there seemingly no USB -> laptop chargers on the market? Wouldn't it be really useful to be able to charge a laptop with a portable USB power brick? submitted by /u/DrywallJackson [link] [comments]

If fire needs oxygen to survive then how some water, 1 part oxygen 2 parts hydrogen doesn't just fuel the fire with the oxygen component? Posted: 11 May 2016 11:48 PM PDT submitted by /u/DakiniBrave [link] [comments]

Why can you only recharge lithium-ion batteries? Why can't you recharge alkaline batteries? Posted: 11 May 2016 08:25 AM PDT What is preventing the opposite redox reaction from occurring in alkaline batteries in order to restore their chemical potential energy? Any links to articles are also helpful. submitted by /u/i_shud_b_studying [link] [comments]

How wide would the Sagittarius A* be, if it wasn't collapsed? What I mean is, it still had the same weight, but the density of earth. Posted: 11 May 2016 11:14 AM PDT submitted by /u/Karmaa [link] [comments]

How do antiperspirants work chemically? Posted: 11 May 2016 04:52 AM PDT From doing my own research I have seen only generalized examples of the reactions that make antiperspirants block the eccrine gland, but was looking for a more in-depth answer on the chemical reactions which lead the aluminum salts to reduce, and what reactions occur that cause the aluminum ions to cause the sweat glands to close. submitted by /u/FreshKhan [link] [comments]

Human females are born with a set number of eggs and can't generate more. Are all animals like this, especially egg-laying hens? Posted: 11 May 2016 06:11 AM PDT submitted by /u/GWFKegel [link] [comments]

Nocturnal Dinosaurs, evidence and how common? Posted: 11 May 2016 05:41 PM PDT We have predators today that are nocturnal. We have raptors (more closely related to dinosaurs than reptiles). It seems almost certain there would have been nocturnal dinosaurs. Are there any studies or evidence of there being nocturnal dinosaurs yet or are we left to speculation and assumption? How common would it have been? What in the fossil record indicates whether a creature was nocturnal or not? submitted by /u/Evoraist [link] [comments]

What does the Falcon 9 use to stabilize itself when landing? Posted: 11 May 2016 05:29 AM PDT What we see on camera here seems physically impossible, as it looks like the rocket is only being propelled from the bottom, making it practically impossible to counteract net torque. When it comes down it's like trying to balance a pen its tip: any slight deviation will make it fall over. Does it have some extra jets that I can not see, or does it control the lower propultion jet ridiculously accurately or what? I know there has to be something I am missing. submitted by /u/JooJoona [link] [comments]

Is the element at 118 on the periodic table the last element that can possibly exist, or is it feasible that elements higher than that could exist with more protons in the nucleus, or electron orbitals higher than 7p, etc? Posted: 10 May 2016 05:06 PM PDT Just played around with an online tool that showed electron spins in the various orbitals for each element on the periodic table. It got me thinking why does the orbital stop at 7p - could a 7d+ exist? Why or why not? submitted by /u/iOSbrogrammer [link] [comments]

Why did trilobites go extinct? Posted: 10 May 2016 08:57 PM PDT Trilobites were plentiful in the Earth's oceans for over 200 million years, and seem to have had a very simple formula for existing, similar to insects - armored swarms that have many offspring over their lifetimes. However, they completely disappeared, in spite of their diversity and simplicity. How did conditions change so that even the trilobites couldn't survive? submitted by /u/day-of-the-moon [link] [comments]

Electrostatics phenomenon: moving charge lights up a fluorescent lamp.? Posted: 10 May 2016 08:27 PM PDT I'm messing around with electricity for a class on electrostatics. I have a toy latex balloon (about 8 inch diameter blown up) and an unmounted fluorescent bulb, specifically an F8T5 lamp, which is about 12 inches long. It seems I can light up the tube just by moving a charged balloon around nearby. Can you explain this? I charge the balloon by rubbing it on my shirt. The lamp is held in one hand at one end. In my other hand is the charged balloon. Now if I just wave the balloon around, or back and forth, the fluorescent lamp will glow, bright enough to see in a room with dim lighting. It also works if the lamp is laid on a table and the balloon waved around it a few inches away. If the balloon is not moving relative to the tube there is no light. I don't understand what is causing the light (presumably a discharge in the tube) when I wave the balloon around a few inches away. There are no sparks or audible crackles that I can perceive. The balloon needs to be moving just a few inches per second to make the lamp light up, and can cause the light from a distance of 5-10 inches. submitted by /u/Man_from_Neptune [link] [comments]

Why is there such a disparity between the redshift value of the CMB and that of the most distant astronomical object observed? Posted: 10 May 2016 08:18 PM PDT The numerical value of the cosmic microwave background's redshift is 1089 and Wikipedia lists one of the most distant objects, galaxy GN-z11, as having a redshift of 11.1. What accounts for the disparity in redshift values between the CMB and a high-redshift galaxy? submitted by /u/TarntKarntington [link] [comments]

Could there be objects that have a figure-8 shaped orbit around the sun and the Alpha Centauri System? Posted: 10 May 2016 06:53 PM PDT According to Wikipedia, the oort cloud could extend as far from the Sun as 200,000 AU (3.2 ly). This would put parts of it well inside the sphere of influence of Alpha Centauri, which is 4.37 ly away. Based on this, it seems possible that objects could orbit both the Sun and the Alpha Centauri system in a figure-8 shaped orbit. Is this possible? submitted by /u/mattenthehat [link] [comments]

Posted: 10 May 2016 12:30 PM PDT If the lowest temperature measured on Antarctica today is −89.2 °C what was the lowest possible temperature there during the last ice age and is it possible that there was frozen CO2 (dry ice) on Antarctica during the ice age? submitted by /u/torrio888 [link] [comments]

What causes a Coronal Mass Ejection? Posted: 10 May 2016 04:58 PM PDT I am doing a research paper on CME's when I came to this question. Seemingly simple, it appears that there are several schools of thought on the matter from shock time of arrival model to the ENLIL model to the interplanetary magnetic field model. Is there a "right" model or is it still up for debate? Thank you submitted by /u/mrskeletaldootdoot1 [link] [comments]

Is it possible to not lose weight when on a calorie deficit? Posted: 10 May 2016 06:33 PM PDT A pound of fat gives you 3500 calories, while (from what I've been told) a pound of muscle requires around 2500 calories, if you were to add a pound of muscle while removing a pound of fat, would you stay at the same weight even with a 1000 calorie deficit? submitted by /u/NewbeginningNewStart [link] [comments]

Is our emotional response to certain colors caused by nature or nurture? Posted: 10 May 2016 05:49 PM PDT Most people have a similar emotional reaction to certain colors. Have these reactions been hardwired into our DNA or are they taught to us? For example, perhaps over centuries of evaluation green became so associated with plants, food, health etc that we instinctively know this at birth. Im sure someone, somewhere has tested this but Ive never read a study. What would be ways of testing this? I was thinking maybe examining responses to color across cultures would be one way. submitted by /u/MittenMan- [link] [comments]

How strong is solar wind, and/or radiation pressure? Is it strong enough to have a major effect on the path of a manned mission to let's say Mars? Posted: 10 May 2016 09:00 PM PDT I know that we have designed ships based on the pressure of the light coming off the Sun, but would it be possible that it could have an affect on the long term path of a manned or unmanned object? For example, did they have to calculate it into the trajectory of Curiosity? submitted by /u/TheLegendaryBagel [link] [comments]

In, lets say, an electric dc motor in a vacuum, given it rotates it means it has acceleration. If it has acceleration with a consistent power, besides friction what inhibits its from reaching extremely fast top speed/breaking point? Posted: 10 May 2016 05:48 PM PDT Just wanted to attempt to design a simple dc electric motor that goes really fast. This question got me curious. Why don't spinning motors accelerate to oblivion ? submitted by /u/MrNomad101 [link] [comments]

Why does silica gel absorb water so effectively, and why only water? Posted: 10 May 2016 12:14 PM PDT I've been trying to persuade it to absorb ethyl and methyl alcohol with metal salts dissolved in it, to create potentially long-burning coloured fire fuels, but it won't have any of it, nor a few other solvents I have rattling about. So I'm wondering what is so unique about water that enables it to absorb monumental amounts? And is there a way I can make it absorb m/ethyl alcohol in the same way? Thanks for your knowledge and insights. submitted by /u/SilverHornet [link] [comments]

Since 2008, I've worked at the intersection of Open Science, altmetrics, and academic library services with teams at Impactstory, Indiana University , PLOS, and now Altmetric. AMA! Posted: 10 May 2016 04:49 AM PDT Hi, I am Stacy Konkiel, Outreach & Engagement Manager at Altmetric, and I'm here to talk about whether the metrics and indicators we like to rely upon in science (impact factor, altmetrics, citation counts, etc) to understand "broader impact" and "intellectual merit" are actually measuring what we purport they measure. I'm not sure they do. Instead, I think that right now we're just using rough proxies to understand influence and attention, and that we're in danger of abusing the metrics that are supposed to save us all--altmetrics--just like science has done with the journal impact factor. But altmetrics and other research metrics don't have to be Taylorist tools of control. I love the promise they hold for scientists who want to truly understand how their research is truly changing the world. I especially appreciate the fact that newer metrics allow the "invisible work" that's being done in science (the data curators, the software developers, etc) can be recognized on its standalone merits, rather than as a byproduct of the publication process. That's been my favorite part of working for Altmetric and, previously, Impactstory--that I can help others to better value the work of grad students, librarians, data scientists, etc. Today, I want to talk about better measuring research impact, but I'm also open to taking other relevant questions. There will also be some live tweeting from @Altmetric and @digitalsci and questions using the #askstacyaltmetric hashtag. I will be back at 1 pm EDT (6 pm BST, 5 pm UTC, 10 am PDT) to answer questions, AMA! submitted by /u/Stacy_Konkiel [link] [comments]

What is our solar systems orientation as we travel around the Milky Way? Are other solar systems the same?

How can standing waves exist without propagating an ideal distance between two points that is exactly equal to a multiple of the wavelength, which is impossible? Posted: 09 May 2016 07:46 PM PDT If I'm constructing a speaker box for waves of wavelength 1 meter, and I try to space the inside faces of the box at a distance of 1 meter, inevitably the true distance will be 1.0001 meters or something. Wouldn't the waves from the speaker provide less and less constructive interference, and then destructive interference as opposing waves became out of phase? Or do they just fizzle out before this happens? A follow up question would be: What is wavelength dependent on? All the waves coming from a speaker must be the same wavelength, or constructing a measured speaker box to induce constructive interference would only amplify a small fraction of the waves produced by the speaker, right? submitted by /u/stir_fry [link] [comments]

How many atom/molecules of a compound/matter do you need to identify the compound's phase? Posted: 10 May 2016 03:30 AM PDT Can a single molecule of water be considered a solid, liquid or gas, for example? Or, for that matter how many Carbon atoms would you need to determine if you were looking at graphite or diamond? Would it depend on the it's crystalline structure? submitted by /u/axis_of_weevil [link] [comments]

What phonon modes are occupied at temperatures above the Debye temperature? Posted: 09 May 2016 05:22 PM PDT My understanding of the Debye frequency is that it's the highest energy lattice vibration. Molecular solids have low Debye temperatures (~101 K). If there is a process that needs significantly more energy than the Debye frequency, where does it get the energy? Multiple phonons at the Debye frequency? I'm specifically thinking about spin-phonon interactions, where excitations in the spin manifold are (*can be) on the order of 102 K and the Debye temperature is 101 K. More general discussion and references are definitely welcome. submitted by /u/qweoin [link] [comments]

Do we know where the Sun's mother is? Posted: 09 May 2016 09:45 AM PDT My understanding is that the fact that the Earth has elements heavier than iron in it demonstrates that our solar system, including all the hydrogen in the Sun, comes from the residue of an explosion of a supernova long ago. That would seem to imply that the explosion from which our solar system came also produced other objects, including a black hole at the center of the explosion, and possibly other solar systems made up from other parts of the jetsam of the supernova. My question is: do we know where the black hole is that we came from -- in other words, the Sun's "mother"? Do we know where any of our sister solar systems are? Are these objects nearby, compared to the size of the Milky Way? submitted by /u/meltingintoice [link] [comments]
