| Posted: 27 May 2017 06:30 PM PDT I know how people make their own artificial lakes, but they need to put a tarp down to keep the water from draining away. How do rivers and such not have water seep away through the ground? [link] [comments]  |
| What will happen to the Voyager spacecraft if they never come into contact with anything? Posted: 27 May 2017 06:59 PM PDT Considering space is mostly 'empty' and that the distance between stars, galaxies and other structures is huge, is it possible that the voyager spacecraft could continue to travel forever without hitting anything? Could it theoretically outlive stars, and make it to the end of the universe? Or would the metals and materials its made of eventually break down? It amazes me that a human-made object could potentially outlive humanity, and even our sun! [link] [comments]  |

| Why do we find C14 in diamonds? Posted: 27 May 2017 11:32 PM PDT One argument I often find posed by Creationists is that C14 is found in subterranean materials which should be too old to have it, such as diamonds and coal deposits. Thus, the materials cannot be as old as posited by standard dating. Do we actually find C14 in these materials, and if so why? [link] [comments]  |

| Why does the Derivative term often add to instability in PID controllers? Posted: 27 May 2017 04:58 PM PDT If possible I'd like an explanation in terms of the actual math behind it. Unfortunately the Wikipedia page has a citation but it was never defined. https://en.m.wikipedia.org/wiki/PID_controller#Derivative_term [link] [comments]  |
| Can seemingly clear gases be seen with electromagnetic waves not visible to the human eye? Posted: 27 May 2017 02:19 PM PDT Saw this on the front page and started thinking about all the things that can only be seen with infrared and made me wonder if it worked with Oxygen or nitrogen or some other seemingly clear gas.

| How does a Boiling water reaction work? Posted: 28 May 2017 03:53 AM PDT For a physics project I'm reasearching how a BWR works. I know the basics by know but I can't seem to find a clear answer to my questions: Other than in the turbines is there an efficiency rate? I mean is there a loss in energy from the boiling water in the reactor towards the turbines. Also, it would be really helpful if anyone could tell me how you calculate the mass of the Uranium when knowing the total annual effect. I've got mostly everything else for my project but these two questions are hard. Anyone care to help? [link] [comments]  |
| Posted: 27 May 2017 04:28 PM PDT See this gif: http://i.imgur.com/UUyVeIV.gifv The dog is spraying the water off his body at the front, then the middle, then it finally shakes off the back and tail. Why does this happen/why does the dog do this? [link] [comments]  |

| Why can't you donate blood after an endoscopy? Posted: 27 May 2017 11:42 AM PDT In the UK you cannot donate blood for 4 months after an endoscopy. Considering the procedure doesn't interfere with your blood, or leave physical impacts on your body (hopefully), why is this? [link] [comments]  |
| What does it mean that photons are the force carriers for electromagnetism? Posted: 27 May 2017 01:53 PM PDT I understand that a photon is a self-propagating wave in the electromagnetic field, and I understand at some level that charged particles interact by exchanging photons... but how does that actually work? It sounds like it means that charged particles are constantly emitting photons, which is what gives them their charge, but that seems impossible (where would all the energy come from?). What's actually going on when two particles interact? [link] [comments]  |
| Posted: 27 May 2017 02:31 PM PDT That is to say, is there some point in pi where there is a series of sequential 4's longer than the amount of numbers preceding it? If it is not inevitable, then how would you go about calculating the probability that such an event would occur? Is it possible to calculate that probability for any arbitrary infinite string of digits? If so, what is it? Edit: spelling. [link] [comments]  |
| What are the theorized properties of stable super heavy elements? Posted: 27 May 2017 06:13 PM PDT Are there any solid ideas of what properties any super heavy elements in the island of stability might have, based on their group, crystal structure, or anything else? [link] [comments]  |
| how do displacement currents flow through the plates of a capacitor? Posted: 27 May 2017 12:42 PM PDT Suppose there is a capacitor connected to a battery . If conduction currents can't flow through the plates of a capacitor , how is it possible for displacement currents to do so? Also , how are they equal in magnitude as conduction currents ?
