| In an SSD drive, how is the data persistent, even if the power is off? Posted: 20 Nov 2018 03:23 AM PST I'm a CS student and I know the ins and outs of data storage in RAM. But RAM needs electricity to save data. Since an SSD (I assume) uses the same basic technology, how is it possible that we can take it off the grid and the data is still saved? [link] [comments]  |

| What determines what wavelength of light is reflected from object? Posted: 19 Nov 2018 09:39 PM PST If i have a green apple, shined on by light from sun. The apple appears green. Because all wavelengths of light are absorbed except for some that appear green to us. But what determines the color of the apple? Is it the size of the molecules on the apple surface?

| How does helium cause a MEMS oscillator to stop working? Posted: 19 Nov 2018 03:00 PM PST Helium has recently been identified as the culprit in killing some Apple hardware, due to interfering with MEMS oscillators: https://www.reddit.com/r/sysadmin/comments/9mk2o7/mri_disabled_every_ios_device_in_facility/ Is the oscillator small enough that individual helium atoms can jam between the moving parts? Is it some sort of chemical effect? What's actually going on? [link] [comments]  |
| Posted: 19 Nov 2018 05:13 PM PST Presumably for the past 10,000 years, the people of North Sentinel Island have been procreating with around 100-1000 people. With a gene pool that small how are the islanders not suffering from genetic diseases? Is there a specific reason, or have they just been maintaining genetic diversity. [link] [comments]  |

| Posted: 19 Nov 2018 04:28 AM PST Just wanna know if there is a difference if I stay up for 24 hours and I sleep for 7-8 hours, compared to if I were awake for 12-18 hours and got the same amount of sleep. [link] [comments]  |
| Posted: 19 Nov 2018 09:03 PM PST I'm speaking particularly about the common representation of a photon as two in-phase sine waves at right angles to each other. What exactly is oscillating? A couple places said it was the magnitude of each respective field, which I think refers to the strength and length(?) of the field lines "generated" by the field. But what shape do the field lines take? Is it the kind of pattern you would see with, say, iron fillings and a bar magnet? Additionally, the fields are projected in the 3rd dimension right? How can they be rotated at 90% then? Or is it something to do with quantum numbers? When the magnitudes of both waves reaches 0, do the fields diminish to nothing or just stop influencing anything around them? If someone put a magnet near a stream of radio wave with a noticeably long wavelength, could the exertion of forces on the magnet be detected? Sorry I don't really understand EM waves at all and I'm probably dumb for trying to understand with a cursory knowledge of physics. [link] [comments]  |

| Are there such things as albino variants of trees? Posted: 19 Nov 2018 08:37 AM PST My wife and I bought a new house over the summer. When we first moved in I noticed this "white" sapling growing in our yard. I thought it might just be a nitrogen deficiency, but I decided to let it keep growing and see what happens. The sapling has grown quite a bit, but all the new leaves are white. Here's a picture: https://imgur.com/gallery/IIM17th The plants around it don't seem to have any issues with white leaves and there are several more of this type of tree around that look normal. Could this be an "albino" version of this type of tree? I spend a lot of time in the woods and whatever this tree is, it's pretty common around here, but I have never seen this white leaf variety. Thanks in advance. [link] [comments]  |

| What is the rate of decay of Long-Term Potentiation (LTP)? Posted: 19 Nov 2018 10:21 PM PST In other words, at what rate do the synaptic connections formed during LTP decay as a result of inactivity? The reason I'm asking is because I'd like to know how quickly we forget learned "skills". [link] [comments]  |
| Does quantum superposition affect every observer individually? Posted: 19 Nov 2018 05:45 PM PST Schrodingers cat is an example of how a system exists in all of it's possible states until it's observed, and then it collapses into one of them. But what if the schrodingers cat box is contained within another steel box along with the observer. When the observer opens the cats box, the wave function collapses and the observer sees one state or the other, but for another observer outside of the outer box would the state of the cat still be a superposition of the dead or alive state since he didnt observe the box? In other words can a quantum superposition collapse for one observer but not the other? [link] [comments]  |
| How does a low battery in a kid's toy affect the frequency of the audio output? Posted: 19 Nov 2018 10:53 AM PST I recently watched this video: https://www.youtube.com/watch?v=wMmEnbryZnA And I was wondering how those sound clips could get distorted by a low voltage battery. [link] [comments]  |
| How are these kinds of layered stones formed? (Image inside) Posted: 19 Nov 2018 08:22 AM PST Some nine years ago, when I was still in school, I had found a strange looking stone with layered patterns. Recently looking at my old stuff, I found it again. Which makes me wonder how these kinds of layers are formed: Edit: The sample is about 4 centimeters long, 3 centimeters wide and about 2.5 centimeters in height. I found it in my school playground just lying in the dust among other things, and live in India, the westernmost part. The color of the rock is actually yellowish to yellow-orange and slightly brown in some places. [link] [comments]  |
