| What is happening during a Mandelbrot zoom? Posted: 25 Mar 2018 09:38 PM PDT I recently found out that watching Mandelbrot zoom's on YouTube is a ton of fun. https://www.youtube.com/watch?v=aHkQjdh14cc I don't know a lot about math. I understand the function and I understand the concept, but what the heck is going on with this video? [link] [comments]  |

| Relative to their size, how far away are galaxies to each other? Posted: 25 Mar 2018 02:48 PM PDT For example; is the average distance between galaxies 10,000 times their diameter? [link] [comments]  |
| Posted: 26 Mar 2018 08:19 AM PDT I'm specifically thinking about positive point charges. When calculating the potential at a point between two point charges will they always add? Is that the point of them being scalar? I'll be the first to admit that physics terminology usually goes over my head. [link] [comments]  |

| What exactly causes you to instantly lose consciousness with a blow to the head? Posted: 26 Mar 2018 07:41 AM PDT I was thinking about this yesterday and thought I'd ask.. I've been knocked out a couple of times over the years due to various cycling fails and don't really understand what happens. What is it about a sharp blow to the head that causes the instant loss of consciousness? Does it do something physical like scramble signals, or is it a reaction to the impact designed to protect us, or something different entirely? Whatever it is, I'd love to know. [link] [comments]  |

| Posted: 25 Mar 2018 12:03 PM PDT Is it going to be bigger, in terms of body weight and rate of growth? Is it going to be stronger? Will its cognitive development start as if it was born after a complete pregnancy or no? Basically after a month will it be able to react to stimuli as a baby that did 9 months in the womb and then a month out or will it behave as a baby born at 8 months? [link] [comments]  |
| Posted: 25 Mar 2018 11:08 PM PDT I've heard from a video about wastewater treatment plants that good bacteria is used to eat harmful microorganisms and pathogens from the dirty water as a step in the purification process. Where does the plant initially get the good bacteria from? How does the good bacteria stay alive, but the pathogens die? [link] [comments]  |

| Posted: 26 Mar 2018 05:50 AM PDT Hi all, Just a query I have. I think I have a rough idea that the difference in reactivity worth may be due to the variation in flux distribution ( as a result of the the fuel loading pattern) and that reactivity worth is an important parameter as it specifies the safety margin of a reactor. If somone could explain in more detail why exactly regulation limits the number and depth at full power that would be great - it would also be interesting to know if there is much variance between international regulation upon this matter and why at full power it is such a problem. Thanks! [link] [comments]  |
| Why where Fat Man and Little Boy shaped differently? Posted: 26 Mar 2018 05:20 AM PDT This never occurred to me until I saw this meme, but why where Fat Man and Little Boy shaped differently? I understand that they where different sizes with different yields, but why where their silhouettes so different from one another? [link] [comments]  |

| What's the difference between the Observer Effect and the Uncertainty Principle? Posted: 25 Mar 2018 01:20 PM PDT There is an unbelievably large amount of misinformation about both of these things it is hard to get an answer. From what I understand the uncertainty principle is when you send electromagnetic waves to observe particles but because of how small particles are you need to make the wavelength shorter and the frequency higher so that it interacts with the particle but the more you do this the higher the uncertainty of the position and the velocity of the particle is since the process of doing that disturbs the particle. I have tried looking up the observer effect and either people start talking about consciousness or I see Neil deGrasse Tyson talking to Joe Rogan and he says that it is the same thing and then I look in the comment section and they say that he is simplifying it or just getting it completely wrong (although the comment section have been known for getting things wrong themselves). The only other thing is the odd mention of the double split experiment or superposition - both of which I vaguely understand the basic principle behind but I don't really understand what is happening on a Quantum scale.

| Do trees contribute to the environment when they lose their leaves? Posted: 26 Mar 2018 04:22 AM PDT For example they photosynthesise to replace oxygen in the atmosphere which is very useful to humans - do they continue to do this during the winter without leaves? [link] [comments]  |
