| How was quantum entanglement discovered? Posted: 11 Feb 2017 05:54 AM PST I can't find a single source that gives me a precise answer. If it was through a mathematical equation. Which was it? Also, under what conditions and how can you make two particles entangled? [link] [comments]  |
| What is exactly potential energy? Posted: 11 Feb 2017 05:18 AM PST It always blows my mind to think about it. How can two identical objects have a different amount of energy just because one is further away from Earth than the other? Wouldn't that make everything on earth have a massive amount of energy compared to a faraway black hole? And since energy isn't created or destroyed, what happens to the energy I spend lifting an apple outside of Earth's gravitational field? Can it be measured? [link] [comments]  |
| What is the physical basis for electric charge? Posted: 10 Feb 2017 07:46 PM PST That is, what is it about protons that attracts electrons and repels other protons and vice-versa? Or is it one of those things where that's just the way it is and nobody knows why yet? [link] [comments]  |
| What's causing violent stroms (great red spot) on Jupiter? Posted: 11 Feb 2017 12:24 AM PST In few billion years everything should have been settled down. right? We see stroms here on earth, but we also have life here to disturb atmosphere. [link] [comments]  |
| Posted: 11 Feb 2017 06:04 AM PST Can anyone tell me the specific reasoning that LEDs work better at colder temps? I have found numerous articles and websites saying this is the case, but no real actual explanation. Is it because the cold can assist with combatting heat from the light itself, thus lengthening its life? [link] [comments]  |
| What are the limits of visual recall in memory? Posted: 10 Feb 2017 06:38 PM PST I've heard about eidetic recall of text strings, numbers, or events, but how vividly can an image or scene be recalled? For example this artist apparently drew Manhattan after a brief helicopter ride (though honestly, there are missing or inaccurate details). [link] [comments]  |
| What are the effects of masturbation on motivation, productivity and non sexual relationships? Posted: 10 Feb 2017 11:04 AM PST |
| Posted: 10 Feb 2017 12:44 PM PST If a galaxy 2 million light years away is coming toward us and we see it as it was 2 million light years ago, doesn't that mean it's already here? [link] [comments]  |
| Why can't we just shut the Fukushima Reactor down by inserting control rods? Posted: 10 Feb 2017 02:57 PM PST Use the same weapons technology we have for delivering bunker busting warheads but interject control rods instead. Turn the entire reactor into a pin cushion for control rods. [link] [comments]  |
| Why isn't the Earth constantly shedding mass? Posted: 11 Feb 2017 03:56 AM PST This is something I just thought of a few days ago and has been bugging me. We know the surface of the Earth is covered in gasses that comprise the atmosphere. In chemistry, I remember learning how gasses behave like collections of gaseous particles bouncing off of each other, with each collision sending two particles in different directions. Presumably, some of these collisions will send particles shooting off into space. Obviously, gravity plays a huge part in stopping escaping particles and pulling them back to Earth. However, in addition, I remember that when an object hits a certain speed (Earths escape velocity), its rate of deceleration from gravity is insufficient to stop it from traveling into space indefinitely. I assume gaseous particles travel fast enough to meet that requirement, at least some of the time. As far as I know, there is no source that replenishes Earth's mass in the same way that the sun does for energy. Given these observations, over time, the Earth would constantly be losing mass (specifically it's atmosphere) into space, but I've never heard of any theory like this before. Does this happen? And if not, why? [link] [comments]  |
| Why aren't more vaccines oral? Posted: 10 Feb 2017 02:33 PM PST It seems a large problem with vaccination efforts is that it requires a trained nurse to deliver the injection. That hiders vaccination efforts in rural underdeveloped areas. So why don't we have more oral vaccines? (If the stomaches acidity is an issue cant we put it in a capsule...or maybe use a hookworm as a vector) Also, would a skin patch be viable? thanks. [link] [comments]  |

| Is there a limit to the power of chemical explosives? Posted: 10 Feb 2017 09:25 AM PST From my understanding of chemical explosives, it's the sudden release of energy from a high energy bond, down to a lower energy bond. Is there a theoretical limit, to the power of these explosives (say per 10g of explosive), due to the bonds physically having to much engery to stay stable. [link] [comments]  |

| Is there such thing as Zero Point Energy? Posted: 10 Feb 2017 06:56 PM PST Is Zero Point energy the same as energy of the vacuum? Could zero-point energy be used to power humanity if the right technology was developed? Is there such a thing, even theoretically? [link] [comments]  |
| When and where did the fused human chromosome 2 originate? Posted: 10 Feb 2017 09:27 AM PST I imagine ancient DNA evidence could provide at least a minimum age for the mutation. How much is known about the origin of chromosome 2? [link] [comments]  |
| Posted: 10 Feb 2017 12:40 PM PST I was considering the fact that RGB displays, like smartphones, consist of tiny pixels that represent a specific colour and, combined, can blend to create more colours. But since all these pixels are separated, unlike true white light, then why can they create the colour white? Wouldn't they be doomed to always being slightly off-white since they literally come from different areas of the screen (albeit right next to each other) and not just a single point of origin? If the colours we perceive are different wave lengths on the EM spectrum, then how is a blue photon different from a red photon? [link] [comments]  |
| have we ever observed a black hole evaporating (dying)? Posted: 10 Feb 2017 11:43 AM PST hawking radiation until its fully radiated itself to nothing? [link] [comments]  |
