| Is there an "absolute zero" speed? Posted: 24 Feb 2017 05:03 AM PST It's pretty commonly known that the speed of light is the fastest possible speed in the universe, and that it is impossible for matter to go that fast. Even if they did reach that speed things would appear strange thanks to relativity. What about the opposite though? Is there an equivalent "absolute zero" speed? Would there be any weird consequences with relativity? [link] [comments]  |

| Why are the air intakes of fighter jets so often on the bottom of the plane? Posted: 24 Feb 2017 03:27 AM PST Just as an example, the F-16 is like a vacuum cleaner, and will suck up ANYTHING off the ground nearby. That's a problem when rocks, tools, and bolts, get sucked up into the air intake, so I'm wondering why they continue to be below wing level. As I'm not an aeronautical engineer, the only good reason I can think of so far is to have the cockpit out from in front of the intake. Is there more to it? [link] [comments]  |
| [Psych] Is priming though question order a concern when creating psychometric tests? Posted: 23 Feb 2017 08:30 PM PST For instance, if you ask someone how many dates they've had in the last month, and then ask them how happy they are, their second answer is likely to be more affected by the first than if you'd just asked them about their happiness, since they're now thinking about happiness with a focus on romantic success. I would imagine that this kind of thing happens in a lot of cases, and that question order has a significant impact on the results of psychometric tests. Does this have a significant effect, and if so, how do psychologists tackle this issue when creating questionnaires? [link] [comments]  |

| Time Dilation from the perspective of a Muon? Posted: 23 Feb 2017 10:32 PM PST Hello everyone. I've been trying to wrap my head around this fully for the past couple of days, but I haven't found a clear answer on this specifically. In regards to time dilation,we know that on earth, we observe a much longer lifetime for the muon than they do, with their proper time being around 2.2 us. From the muon perspective, though, shouldn't it also see us as being slower as well? Mathmatically, would it observe a time dilation of t/gamma2, where t is the original measured time by a a stationary observer on the earth? If not, what am I missing, as I am still struggling with this. [link] [comments]  |
| What makes something a strong acid? Posted: 23 Feb 2017 11:08 PM PST I understand that strong acids, like HCl, completely dissociate in solution but what makes HCl a strong acid in the first place? What are the properties of its individual components that cause it to be a strong acid? [link] [comments]  |

| Are there better odds if the person switches the case at the end of Deal or no deal? Posted: 23 Feb 2017 11:59 PM PST Wouldn't it be the same s the monty hall paradox or is it different because the person chose the cases and not the host? here is what I mean. https://www.youtube.com/watch?v=H9CQscwXBt0&lc=z13jcbwaewvkwz1i504cc11rtvnjjjdrixg0k.1487888698718059 [link] [comments]  |

| Posted: 23 Feb 2017 07:47 AM PST If I am walking near the LHC on the surface how close would I have to be for my magnetic compass to drift an appreciable amount due to the strong magnetic field? [link] [comments]  |

| How much of a problem are the high energy neutrons from the ITER? Posted: 23 Feb 2017 09:02 PM PST I know that they're apparently using a lithium blanket to absorb them, but I was unclear if it completely addresses the problem. [link] [comments]  |

| How does the body handle excess amounts of Vitamin C? Posted: 23 Feb 2017 07:59 AM PST Many people start mega dosing Vitamin C when they feel the effects of a cold coming on. After reading a few sources today, I've come across a few that say that, as vitamin C is water soluble, a small amount exceeding the DV is excreted. I've also read that it definitely is not excreted, and that Vitamin C excretion is a blatant myth. Additionally, some sources say that in times of sickness or a stressed immune system, exceeding the DV, as long as the dosing is broken up throughout the day, does help boost the immune system and, as the body uses this excess Vitamin C, it is generally not excreted. So what's the truth? Any recommended sources I can read? (My last post was worthy of r/titlegore, so I reposted.) [link] [comments]  |
| Is the power spectrum of a real signal always of positive amplitude? Posted: 23 Feb 2017 09:33 PM PST The power spectrum, P_T1, of a time series, T1, is the Fourier transform of the autocorrelation of T1. If T1 is purely real, then for negative frequencies, P_T1 is simply the complex conjugate of itself for positive frequencies. But does the amplitude of P_T1 have to be positive? As far as I can tell, there is nothing specific about the Fourier transform or autocorrelation that requires P_T1 to have a positive amplitude for its entire (frequency) domain. Yet for all the spectra I see, they are always positive-valued. Why is this? [link] [comments]  |
