| In a rotating black hole, what is rotating? Posted: 24 Apr 2018 02:30 AM PDT Just something that crossed my mind recently, since the horizon isn't made up of anything. What is the rotating. Or is it just a way to allow for the conservation of angular momentum without having to go inside the BH with our current understanding? [link] [comments]  |

| How easy is it to find a polynomial function of degree n to match n value-pairs? Posted: 24 Apr 2018 05:30 AM PDT I have a dim memory, that my math teacher once said, he can "easily" find such a polynom. Doing that with value pairs (x,y) where they have a form of (x,0) is trivial, so I think it could be possible to do manually. Do you know of any viable method, or did my memory play a trick on me?

| How did they set the exact moment (not duration) of the second pulse of Universal Time (UTC)? Posted: 23 Apr 2018 03:50 PM PDT How did they find the exact nanosecond to place the second pulse? Is it set exactly to the split second from solar mean time? Or did they just find an arbitrary moment approximately about mean solar noon? Why isn't the time 0,5 second ahead, or a half minute?

| How many photons do we see per star? Posted: 23 Apr 2018 11:11 PM PDT Some stars seem brighter than others. At first thought, I would think that we see more photons from it. But then I think about how wide of an angle a star is shooting photons in all direction... and how far we are away, and the very very pricise angle needed to hit our eyes. I think the number of photons being released by a star has to be astronomical even if just 1 or more hit our eyes. I bet the math is beautiful on how we estimate how many photons that a star releases over a time period. [link] [comments]  |
| Posted: 23 Apr 2018 06:31 PM PDT I read about fava beans and see they've historically been a staple-food for mediterranean and north african peoples, and then I read about favism and see that mediterranean and north african peoples are more genetically predisposed to G6PDD. And I wonder...why? [link] [comments]  |
| Can aerodynamic lift be used to increase a road vehicle's fuel efficiency? Posted: 23 Apr 2018 03:54 PM PDT Downforce keeps cars like the Camry "grounded to the ground," are there any practical or theoretical applications of a car's aerodynamics being used to produce minimal or moderate lift at highway speeds?

| What shape(s) are black holes? Posted: 23 Apr 2018 11:59 AM PDT Typically -- we see black holes referred to as a sinkhole of sorts, with a ring that funnels to a singularity. Do we have a definitive concept of black holes, and what their actual shape is? If they're a small ball with a central singularity, or in-fact a ring shape that just orients based on their creation?
