- Old 3D video games rendered circles as visibly crude polygons. Modern games have them perfectly circular. Did we just increase polygon count until its too high to notice, or have rendering algorithms changed to allow "true" circles?

| Why does electricity always hum at a B-flat pitch? Posted: 27 Aug 2017 11:00 AM PDT Whenever I pass a power plant or hear a lot of electricity running through my house, I always hear that pitch. Edit: To those asking, I am a musician. [link] [comments]  |

| If a Train Circling the Globe Traveled Fast Enough, Would the Passengers Inside Float? Posted: 27 Aug 2017 10:19 PM PDT I understand that the concept of "floating" in microgravity is due to a spacecraft moving faster than gravity is able to pull it down resulting in a continuous orbit that "falls" around the Earth. Discounting the practical constraints, would a train moving around the globe at or exceeding escape velocity cause its passengers to experience microgravity? What would the passengers experience as they approached this speed? What would happen when the train exceeded this speed assuming it remained tightly on its track? [link] [comments]  |

| Are there any animals that consume non cellular matter as a significant part of their diet? Posted: 27 Aug 2017 04:11 PM PDT I recall hearing of an animal that will ingest rocks to aid the mechanical act of digestion, but what about for nutritional need? [link] [comments]  |

| Can chickens have identical twins? Posted: 27 Aug 2017 07:52 PM PDT Would they have to come from one egg? I found some references to a chicken with two heads and that sort of thing, but didn't see much about chickens having otherwise normal healthy twin chicks. [link] [comments]  |

| Posted: 28 Aug 2017 06:07 AM PDT Why is it that (molecular) nitrogen is more inert than oxygen that is more inert than flourine? Because Ive learned that a tripple bond is less stable than a double bond, thats less stable than a single bond. Is this because electronegativity becomes higher along that line, and high electronegativity for a two-atom gas is more important for high reactivity than the bond order? [link] [comments]  |

| What are the implications of finding magnetic monopoles? Posted: 27 Aug 2017 02:02 PM PDT If we were to find magnetic monopoles exist and potentially also make them, what would it mean for science? What would be the implications for normal life? [link] [comments]  |

| What would Earth's sky look like if a Black Hole was in the Solar System ? Posted: 27 Aug 2017 10:09 AM PDT Assuming that the black hole is small and far enough to not swallow Earth right away. And how would Humanity react to that ? [link] [comments]  |

| What changes does someone go through when acclimating to high altitude? Posted: 27 Aug 2017 09:43 PM PDT I have recently moved from sea level up to 8000ft in elevation. As a runner, this dramatic change makes it difficult to get enough air while I'm running. How does my body adjust itself to receiving thinner air? [link] [comments]  |

| What causes a hurricane to stall in one area for an extended time, as Harvey is doing? Posted: 27 Aug 2017 11:50 PM PDT Hurricane Harvey is currently causing massive flooding hundreds of miles east of where it made landfall. I have read that this is because because it has stalled in one region for days, and is continuously scooping up moisture from the gulf and dumping it over the coast. Why has this hurricane stalled near shore, and what factors make other hurricane likely to do the same? [link] [comments]  |
