| Does a Mayfly, which only lives a day, evolve fast than a human? Posted: 18 Feb 2018 03:50 AM PST This might be really stupid but to me it makes sense, kind of. Evolution is about survival of the fittest right, so the more generations you have the faster changes take place and the weak are weeded out. [link] [comments]  |
| What is the reason for Ethiopia demographic boom in recent years? Posted: 18 Feb 2018 02:48 AM PST I was browsing Wikipedia and according to it, in 2006 it had population of 74 777 981. In 2017, it is supposed to be ~105 350 020. What's the reason for that boom? [link] [comments]  |

| How do earthquakes happen that are far from tectonic plates fault lines? Posted: 18 Feb 2018 05:15 AM PST Yesterday there was an earthquake in the UK. I live in Bristol and felt it. It was very small but it got me thinking...the earthquakes epicentre was apparently located in wales and some 7km underground (I think) but wales or the UK is not really close to a fault line so what may have caused this earthquake?

| Posted: 18 Feb 2018 04:01 AM PST Our moon has a far side never visible from earth (AKA the dark side), and the near side that's always visible. Do other moons in our solar system, or in the galaxy at large, display similar behavior? I'm also pretty curious as to how or why our moon happens to orbit in that way, as another question.

| Posted: 17 Feb 2018 05:36 PM PST When two electric waves heterodyne, they produce two products called sidebands (or heterodynes) equal to the sum and the difference of the original two frequencies. Typically, this phenomenon takes place in a non-linear circuit element, such as a diode or a transistor. Can this also happen if the waves are just moving through space, or maybe confined inside a resonant cavity or waveguide? Is it enough for the two waves to simply superimpose in space and interfere, to create the heterodynes? Or do they need to "multiply" somehow through a diode? [link] [comments]  |
| Is it possible for an object to be travelling so fast it would bounce off the atmosphere? Posted: 17 Feb 2018 11:05 AM PST Basically the title, but is there theoretically a speed/shape that if it were to collide with Earth's atmosphere at a certain angle it would bounce off the atmosphere like a rock skipping on water?

| Is Crystallized Bismuth the Only Instance of Naturally Occurring Right Angles? Posted: 17 Feb 2018 10:03 AM PST Was watching a video about crystallizing bismuth and it occured to me that I can't think of any other place in nature where something forms right angles. Why does bismuth grow in right angles as opposed to more of a fractal shape and does this occur anywhere else in nature? [link] [comments]  |
