- Do elections orbit an atomic nucleus in a 2d disc similarly to celestial objects such as galaxies and planetary rings? Why/ why not? And what's the math behind it.
- How do colligative properties change when talking about non-dilute solutions?
- Can hydrofluric acid be used to quicken lens grinding?
- If I have a non-random sequence, what should I append to it to make it look random? (explanation below)
- In the concept of hybridization of atomic orbitals how come there is no hybridization which does not involve an "s" orbital?
- During capillary action the average gravitational potential energy of the molecules increases. Where does that energy come from?
- Is there a name or term for cellular organelles (like the mitochondria and chloroplast) that were likely derived from symbiotic cooperation between early unicellular organisms?
- Will friction eventually stop a domino line?
- Jupiter is a massive gas giant and yet it has one of the strongest gravitational pulls. How can a planet made mostly of gas have such strong gravitational force?

- The universe is so big! There must be so many chances for life! Why havent we found/heard from any alien species?
- How does an electron move to a lower orbit?
- If Anti Hydrogen (Hydrogen made of antimatter) gives off the same exact spectrum as normal hydrogen, then how do we know that hydrogen we've seen in space is normal matter, not antimatter?

| Posted: 20 Sep 2018 12:42 PM PDT I was out diving today in heavy surf and got advice from the dive master to watch for a set of 3 big waves to come by before surfacing - evidently after 3 big ones, you'll get about 3 or 4 smaller ones, making it much easier to clamber back on to the ladder. I was a little doubtful, but it turned out to provide me the 30 second window I needed to have a substantially easier transition... But it made me wonder: with the same wind pushing the water, why aren't all waves approximately the same size? Why do they come in sets of a few waves at a time, instead of hundreds, or instead of randomly variable waves? Thanks! [link] [comments]  |

| How do colligative properties change when talking about non-dilute solutions? Posted: 21 Sep 2018 04:38 AM PDT I'm curious at what point do the laws pertaining to boiling point, melting point, osmosis pressure and partial point pressure no longer apply to all solute/solvent combinations equally.

| Posted: 21 Sep 2018 02:49 AM PDT There's a sequence of N characters, generated by a simple algorithm that was not designed to make its outputs look random. I can append a sequence of M arbitrary characters to it. My goal is to make the whole sequence of N+M symbols appear as random as possible. I don't know what kind of statistical tests my adversary is going to use. But I know that he has no particular assumptions about what kind of algorithm could have produced the sequence (although, obviously, shorter algorithms are assumed to be more likely, as per Solomonoff's theory of inductive inference). Should I just append M random symbols to it? Or should I try to "compensate" for the non-randomness of the initial sequence? For example, if the initial sequence has a shortage of zeros, should I add more zeros to my sequence to make up for it? Or would it just bring the apparent fidelity even further down? I need the most general answer you can come up with, without any assumptions of the value of N, M, and the algorithm. (I know this whole affair sounds fishy, but I'm not actually doing anything illegal or unethical) [link] [comments]  |

| Posted: 20 Sep 2018 11:02 AM PDT I'm making an index card based evolutionary tree of life for my son. Are there terms for these symbiotic cytoplasm dwellers with genetically distinct DNA from the cell in which they are housed? Is there any consensus on whether these organelles were derived from viruses, bacteria, or archaea? [link] [comments]  |
| Will friction eventually stop a domino line? Posted: 20 Sep 2018 03:35 PM PDT When you knock over the first domino in a line you are essentially putting energy into that system. So since friction takes away energy and makes it unusable will a line of dominoes eventually stop when friction takes enough of the usable energy away, or will the line go on indefinitely?
