| Posted: 06 Nov 2017 08:47 PM PST I know they're pretty uneventful as far as real-world effect, but could a few well-timed mergers have an amplification effect on gravitational distortion in a given area? [link] [comments]  |
| Does a particle have an antiparticle only if it is charged? Posted: 07 Nov 2017 06:12 AM PST Does a particle have an antiparticle only if it is charged? Are the W and W- bosons a particle-antiparticle pair of the same field, or are there two fields? Why do we talk about antineutrino if the neutrino has no charge? Or is it the fermions that have an antiparticle, but in this case why the boson W has its own antiparticle? [link] [comments]  |
| On small, super isolated islands, how does wildlife exist? Posted: 06 Nov 2017 08:36 PM PST I imagine small islands, like less than a square mile, can't support significant wildlife just due to space, resources, etc. But, if there are plants on the island, there would have to be some sort of insect, right? But can there be any major species (lizards, birds, rodents, etc) without the resources to sustain them? And if it is super isolated, would birds even live there? How can there be life on an island so far removed? Even if there are just very simple insects, how did they get there??? I need answers [link] [comments]  |
| Posted: 06 Nov 2017 04:16 PM PST I know we've had super expensive centimeter accurate GPS for a while, for farming and construction and whatnot, but that costs thousands for equipment and subscription. They're starting to put it in phones and autonomous vehicles now. How does it work and who's developing it? [link] [comments]  |

| Posted: 07 Nov 2017 06:13 AM PST Sorry for the long title, but I felt the context was needed. A recent paper by Winder et al. in Nature Neuroscience showed that ongoing neural activity and hemodynamic signals are weakly correlated during resting state in mouse, and that the origin of the hemodynamic signal may not have anything to do with the neural activity. Because the work on the default mode network in humans is mostly based on fMRI studies, does this mean that many, if not most, of this findings are not relevant anymore? Or am I just overinterpreting the situation? If I am, what does this study imply for the future research on the DMN? Thanks! [link] [comments]  |

| Does a superconductor effect non-magnetized ferromagnetic metal? Posted: 07 Nov 2017 03:43 AM PST So say I have a High Temperature Superconductor cooled down with liquid nitrogen and placed a small piece of unmagnetized iron on top like the floating magnet experiment. Does the iron float? is it attracted to the superconductor? Does it become magnetized? Is there no effect? [link] [comments]  |

| Posted: 07 Nov 2017 02:37 AM PST I've been playing basketball recently, and my increasing accuracy made me wonder how it takes place in the brain. Is there some kind of feedback process which rewards your shots getting closer to the hoop (like dopamine released due to satisfaction), thus increasing its likelihood? If so, is it theoretically possible to artificially enhance the process? If it's a result of pleasure guiding the unconscious processes of throwing with increasing accuracy, for example, could small external rewards for accuracy (eg, a hit of nicotine or some sugar) increase the speed of improvement? I understand that with basketball, a large part of increasing accuracy is the conscious aspects of improving your form and cementing that into automaticity. But I'm more interested in the unconscious workings. Say it was with a tennis ball instead, where you are not consciously changing your form but still getting more accurate over time - what's behind these unconscious improvements? Hope this all makes sense. [link] [comments]  |
| Posted: 06 Nov 2017 01:30 PM PST Let me add some context. One of SciShow Space's (from YouTube) recent videos was how an asteroid from outside our solar system has been flung away from its native solar system and has found its way into our own... for the time being. Why can't we (carefully) land a probe on it to freeload on it to the outer reaches of our solar system and beyond? Yes, I'm aware doing it would be extremely difficult, given its size and the theoretical planning that would be involved. But would it be theoretically possible to do it? And would we learn anything from being on it? Thanks, r/askscience! [link] [comments]  |
| Posted: 06 Nov 2017 01:28 PM PST If so, are species of bacteria known to be common between our skin and exoskeletons? [link] [comments]  |
| Variable S in Laplace Transforms? Posted: 06 Nov 2017 12:52 PM PST What exactly is the 's' variable when using Laplace Transformations? My math professor said it was just a complex variable or frequency, but what does that mean? How come it is used to transform a function in terms of time? [link] [comments]  |
| How do we create entangled particles? Posted: 06 Nov 2017 06:53 PM PST I understand the concept, but how can this be achieved physically? And even if we do create them, how can we even measure them? As a secondary question, how is being applied in the development of quantum computing (e.g. entangled qubits?) [link] [comments]  |
| How can operating system tell free memory from used memory ? Posted: 06 Nov 2017 10:07 AM PST How can an operating system tell a free byte from a used byte in memory ? Even if a byte contain 0 it doesn't necessarily mean it isn't used. [link] [comments]  |

| How realistic are sci-fi planets that are almost entirely one biome? Posted: 06 Nov 2017 03:09 PM PST Like how Star Wars has some planets that are just deserts, or just snow and ice, or just oceans, etc. I can kinda see how desert and snowy planets might exist (how far the planet is from their sun), but I'm curious as to how realistic they are.

| How fast could a processor reboot a computer if it wasn't held back by other components? Posted: 06 Nov 2017 07:50 PM PST As i understand it, the CPU (Central Processing Unit) of a computer system is slowed down, or held back (Bottle necked) by the other components of the same system. (Hard Drives, RAM, cache, etc) How much faster would the computer be, if instead, the processor as it is currently, was the bottleneck to the rest of the system components? [link] [comments]  |
| Why does type II deionized water have less resistivity than type III deionized water? Posted: 06 Nov 2017 05:37 PM PST http://puretecwater.com/deionized-water/laboratory-water-quality-standards When ion concentrations for each type go I<II<III<IV, why is the trend for resistivity I>III>II>IV?

| How is an adult able to donate body parts to a child? Posted: 06 Nov 2017 02:41 PM PST Saw a thing on facebook other day about how a father donated a kidney to his infant son. How is that physically possible? [link] [comments]  |
| Have Tectonic plates slowed down over time? Posted: 06 Nov 2017 03:08 PM PST Given all the friction that tectonic plates undergo when they hit each other, I'd imagine that they must slow down a lot over time. Did continents once drift much faster than they do now, or is the earth still relatively "young" and dynamic? [link] [comments]  |
