| What prevents individual cell phone radios from "stepping on" each other's transmissions? Posted: 28 Nov 2016 05:15 AM PST I understand how channel hopping works in wifi and other basic radio technologies, but it seems like deconflicting the transmissions of cell phones in a busy city would pose a problem of a much greater magnitude. How do they do it? [link] [comments]  |
| Why do we need a Higgs Boson for the electroweak force? Posted: 28 Nov 2016 05:13 AM PST I've read about the Higgs field, and seen that it was needed to make the weak forces behave in the way we observe. What I do not get is why can't the W and Z bosons just have mass themselves? What problems would arise if the W and Z bosons themselves had mass? [link] [comments]  |

| Why do some fruits grow in 'slices'? Posted: 27 Nov 2016 02:31 PM PST For example, the clementine or the orange, they come in slices that each have a sort of skin separating them from other slices. Why do these and many other fruits grow like this? [link] [comments]  |

| Does rice contain squalene and linoleic acid? Posted: 28 Nov 2016 04:25 AM PST From what I researched, only the bran contains such nutrients. Does the rice grain itself, separated from the bran, still retain squalene and linoleic acid? [link] [comments]  |

| Is it possible for a disease to span across multiple branches of the animal kingdoms? Posted: 27 Nov 2016 07:30 PM PST Like Arthropods and vertebrates and etc. would suffer from the same disease? Like an ant and spider and snake and dog and pelican could suffer from the exact same disease? [link] [comments]  |
| Does Carnot Heat Efficiency Only Apply to Processes of Turning Heat into Work? Posted: 27 Nov 2016 08:53 PM PST I've seen solar panels that have been said to have over 40% efficiency. I know the Carnot cycle applies to a heat engine, but can you generalize it to say that it's for all processes of turning heat into work? [link] [comments]  |
| How do MC fusion reactors extract usable energy? Posted: 27 Nov 2016 02:20 PM PST Fission reactors seem straight forward enough: hot rods in water produce steam to power turbines. Magnetic confinement fusion seems a but less intuitive. There is no contact between the plasma and structure. How does it convert this energy into electricity or another useful form? [link] [comments]  |
| How do Micro pipettes and Pipettes function? Posted: 27 Nov 2016 06:48 PM PST I understand it works by vacuum, but how did engineers figure the right amount of vacuum for each value?(e.g. how much vacuum is applied to each ml) [link] [comments]  |
| Is it possible for other elements to be the basis of biometabolism? Posted: 27 Nov 2016 03:20 PM PST I read somewhere that hydrogen and sulfur are both possible substitutes for oxygen in the form of redox energy source. How is this possible and are there any examples of organisms getting their energy this way? [link] [comments]  |
| Does magnetic and electric field follow surface area of a sphere? Posted: 27 Nov 2016 04:33 PM PST In the Biot-Savart and Coulomb's law, the denominator has r2, and it's always explained that these laws follow an inverse square relationship with distance. Looking at the formula, though, there's a 4pi term in the denominator. Does this imply that these laws are really operating on the surface area of a sphere, given that the full denomimator is 4pir2 ? After all, the field expands in every direction, so really, saying that it follows an inverse square relationship is a shorthand way of the full explanation that it's inversely-square with distance because an inverse square (r2) means you're dividing the field strength by the surface area of a sphere of radius r. I think this is correct, but am hoping someone can tell me if I am correct or just jumping to conclusions that don't actually exist. [link] [comments]  |
| How does amusia affect speaking tonal languages? Posted: 27 Nov 2016 02:17 PM PST People with amusia are unable to process pitch, meaning they can't distinguish different pitches. Since tonal languages use pitches to distinguish meanings, I'd imagine people with amusia have trouble understanding it. Has there been any research on how this influences speaking and comprehension among other things? [link] [comments]  |
| How does xenon gas produce a positive ion when impacted by an electron? Posted: 27 Nov 2016 01:45 PM PST In ion drives, xenon gas is bombarded by a electron gun which produces positive ions. The ions gets accelerated out of the spacecraft to produce thrust. How does a negative electron make the xenon positive when impacting? Does it impact a electron in the outer shell of the xenon atom and makes it loose conection to the forces of the nucleus? If so, how come that the electrons does not immediately fill this gap to make the xenon neutral again? [link] [comments]  |
| Why can't we see the Andromeda Galaxy? Posted: 27 Nov 2016 09:58 AM PST I keep reading that the Andromeda Galaxy would be larger than the moon in our sky if we could see it. Why can't we? [link] [comments]  |
