| How exactly does a autotldr-bot work? Posted: 10 Jul 2016 05:35 AM PDT Subs like r/worldnews often have a autotldr bot which shortens news articles down by ~80%(+/-). How exactly does this bot know which information is really relevant? I know it has something to do with keywords but they always seem to give a really nice presentation of important facts without mistakes. Edit: Is this the right flair? [link] [comments]  |
| Do lasers work in other parts of the electromagnetic spectrum? Posted: 10 Jul 2016 04:47 AM PDT Can you make a UV laser or a gamma laser? or could you go to the opposite end of the spectrum and make a laser that shoots radio waves? Also would it emit visible light or could you have a laser that is invisible to the human eye? [link] [comments]  |
| Posted: 10 Jul 2016 01:53 AM PDT Surprised that this isn't in the FAQ, but can someone explain the 10/11 dimensions of Superstring/M-Theory? Are there organisms that could experience more dimensions than 3 spacial and 1 time dimension? If some dimensions are curled up and small enough (anywhere from planck length to 1mm) could microscopic bots experience these dimensions? [link] [comments]  |
| How permanent is a permanent magnet? Posted: 10 Jul 2016 07:06 AM PDT If I leave a fridge magnet on my fridge for long enough, will it eventually fall off? Will the magnetism fade away over time? [link] [comments]  |
| Do super massive black holes decay? Posted: 10 Jul 2016 06:16 AM PDT I'm sorry if this has been asked before or if it seems ignorant but recently I've been thinking about black holes. My question is will the super massive black hole at the centre of the Milky Way eventually evaporate causing everything to drift apart? I know that the more massive a black hole is the longer it will take to be decayed by Hawking radiation so it would probably take billions of years to happen but nonetheless I'm curious.

| are CRISPR gene edits carried forward to your children? Posted: 10 Jul 2016 01:34 AM PDT and will edits that carry forward be a problem/benefit in a new individual? trials of CRISPR may be beginning soon so this seems a relevant question. http://www.nature.com/news/first-crispr-clinical-trial-gets-green-light-from-us-panel-1.20137?WT.mc_id=TWT_NatureNews [link] [comments]  |
| How a vector graphics data is stored? Posted: 10 Jul 2016 07:41 AM PDT So, I know that for a raster graphic, computers store the data in a matrix-like structure, with the number representing the color of each pixel. But what about vector graphic? I know that a vector graphic is represented as a mathematical expression. What kind of mathematical expressions are used to store a vector graphic data? How do computers store this mathematical expressions? I was wondering why we don't see vector graphic more commonly as I cannot see its disadvantages over raster graphics. I have a background in math / linear algebra / computer science, so you can explain them with a technical term. [link] [comments]  |
| Why haven't we sent probes to Europa? Posted: 10 Jul 2016 07:32 AM PDT Or Enceladus, or Titan? I mean, I know we sent one to Titan, but why only one? If we think these places may harbor life, not only multicellular life (which would be amazing), but life of any form, why haven't we explored the surface or below yet? As it stands now, me, as an 18 year old, will probably be about 40 by the time we land anything on any of these solar bodies. [link] [comments]  |
| Posted: 09 Jul 2016 01:03 PM PDT Did the sun start out much darker than now and reach its peak and then start decreasing its brightness? [link] [comments]  |
| Can sound have a direct effect on light? Posted: 09 Jul 2016 07:56 PM PDT Take explosions, for example, you can observe the shock wave. Is that the direct result of the sound refracting the light? Or is it the temperature of the surrounding area like in a mirage or something? [link] [comments]  |

| How does density functional theory and programs like Vasp and Quantum Espresso work? Posted: 10 Jul 2016 06:11 AM PDT I'm a 3rd year in Aerospace but looking into materials research in aerospace applications. My professor wants me to look into DFT and the vasp program but the manuals are very dense and difficult to absorb. My current understanding is that you input atomic/electronic positions of a unit cell, tell the program how you want to deform it, then the program applies a periodic condition and outputs a result that you asked for, is this correct? Thanks in advance. [link] [comments]  |

| Posted: 09 Jul 2016 05:44 PM PDT In most settings, taking on water would increase density, so what makes this process different? [link] [comments]  |

| How was gravitational acceleration measured? Posted: 10 Jul 2016 01:17 AM PDT So I know about the story of Galileo and him dropping the two canon balls from the leaning tower of pisa, but how did the value of 9.8m/s/s get discovered? Who first discovered the value of gravitational acceleration, and how did they do it? I would appreciate sources as well please, thanks :) [link] [comments]  |
| Posted: 09 Jul 2016 10:41 PM PDT Not sure how to classify this. Psychology? But is a normal person able to imagine a color they haven't seen, for example would someone who has just managed to avoid the color blue all their life be able to picture blue? And are the colors we know all the colors there are, or just all we see? [link] [comments]  |
| Why is pure carbon typically black when most carbon containing compounds aren't? Posted: 09 Jul 2016 08:28 PM PDT If most allotropes of carbon are black, why are carbon containing compounds usually either white or colorless? [link] [comments]  |
| Why does an atom that gains neutrons become radioactive? Posted: 09 Jul 2016 01:00 PM PDT "Neutrons are much less influential on the chemical character and identity of an atom than protons, although they are just as hard to add to or remove from the nucleus, being so tightly bound. If neutrons are added or gained, the atom will still retain the same chemical identity, but its mass will change slightly and it may acquire strange nuclear properties such as radioactivity" Source: www.allaboutcircuits.com/textbook/direct-current/chpt-1/static-electricity/ [link] [comments]  |
| Whats the deal with absolute zero? Posted: 09 Jul 2016 01:21 PM PDT Why is -273.15°C the lowest possible temperature? What stops it from getting lower than this? [link] [comments]  |
| Posted: 09 Jul 2016 08:41 PM PDT I was drinking a mixed drink with apples and cucumbers in it and wondered, why is it i taste the apple first then the cucumber second after swallowing? does it have to do with where the flavor is on the tongue? [link] [comments]  |
