| How does Quantum Entanglement work? Posted: 01 Dec 2017 02:00 PM PST How do the particles that are entangled manage to always do the opposite of the second one? Are they communicating with each other if so how? Otherwise is it some kind of force? [link] [comments]  |
| Posted: 01 Dec 2017 12:14 PM PST Edit: Specifically for the hydrogen atom for simplicity's sake. Wondering if this change happens at the speed of light or instantaneously and if instantaneously how does it not violate causality. Does it work like wave function collapse? [link] [comments]  |
| Does satellite communication involve different communication protocols? Posted: 01 Dec 2017 09:23 AM PST Are there different TCP, UDP, FTP, SSH, etc. protocols for talking to satellites? For example to compensate for latency and package loss. I imagine normal TCP connections can get pretty rough in these situations. At least with 'normal' settings. [link] [comments]  |

| Posted: 02 Dec 2017 06:36 AM PST I am thinking about this in relation to near earth objects . From what I understand most objects have been on the same trajectories for a really long time which makes collisions pretty rare . If earths trajectory is changing does that increase the likely hood of a collision? [link] [comments]  |
| Are there different types of electrons? Posted: 01 Dec 2017 09:44 AM PST According to the standard model, each particle is an oscillation in a quantum field. There are different energies of photons. Similarly, can an excitation of the electron field have different levels? I know that electrons have different energy levels in an atom, is this a separate concept from the one I described above? [link] [comments]  |
| Why do gases exert constant pressure on container walls? Posted: 02 Dec 2017 01:18 AM PST So pressure is caused because of the force with which gas particles hit the walls of the container, right? But wouldn't a little bit of energy be lost to the walls every time they collide, slowing down the particles over time and consequently lowering the pressure? I guess my question is, where do the molecules get the energy to keep moving around and hit the walls, and wouldn't they eventually lose that energy with every collision? [link] [comments]  |

| Why don't CPUs have dedicated instruction sets for compression? Posted: 01 Dec 2017 07:24 PM PST Computers built in the last decade generally take advantage of the x86 AES instruction set, which is hardware acceleration in the CPU that speeds up the task of encryption or decryption using the standard AES algorithm. Even obsolete processors like mine can encrypt multiple gigabytes per second (!). This vastly exceeds the speed of hard drives, so the result is that there's negligible performance loss for encrypting your data and you might as well encrypt everything all the time. However, another common task, possibly even more common with even more standardized algorithms, is data compression. As far as I can tell there's no hardware acceleration for this. Is there a technical reason why that's not feasible? Something to do with a larger or much more active buffer? What might be the advantages of different compression algorithms for dedicated hardware acceleration? [link] [comments]  |
| Is a twin born through in vitro fertilization more likely to give birth to twins? Posted: 01 Dec 2017 07:38 AM PST As I understand it, twins are more likely to have more twins. Does this hold true if the twin was a twin because of in vitro? [link] [comments]  |
| Posted: 02 Dec 2017 03:20 AM PST If yes, wouldn't that make them gain more energy out of nowhere? If no, does that mean we can slow light down enough to see it move? [link] [comments]  |

| How do we communicate with satellites extremely far away? Posted: 02 Dec 2017 02:56 AM PST After reading an article on Voyager One, I came to realise that I have no idea how communication works over such a long distance. How long does it take for something so far away to receive communication? How fast do the controls on a satellite like Voyager One respond to our communication? What is the delay between sending information and the satellite receiving information? [link] [comments]  |
| What is that new electronics smell? Posted: 01 Dec 2017 12:56 PM PST This might be more of an engineering or technology question. Sorry if this isn't the place for it. I'm writing this on my new phone and am noticing the nice 'new electronics smell' and it smells the same every high-fi, Playstation, TV, computer etc that I've ever opened. Strangely fridges, oven and sewing machines don't have it. What is this smell and why is it only on certain appliances? [link] [comments]  |
