| What causes the patterns to appear in this maple syrup? Posted: 31 Oct 2016 09:03 AM PDT https://gfycat.com/DiligentHardKingfisher I've tried searching for maple syrup ripples/waves/evaporation/pattern but haven't found anything explaining this. I'm guessing it has to do with some of the water from the syrup evaporating, but not sure why it seems to dance around like this. [link] [comments]  |
| How and why acceleration of charged particles produce photons? Posted: 31 Oct 2016 08:35 PM PDT Hi Sciencefolks, Given that acceleration of charged particles produce photons, and vice versa (how antenna and radios work), there are two parts of my question.
Thanks in advance. [link] [comments]  |

| Is there a name for a set of equivalent sums of squares, a^2 + b^2 = c^2 + d^2? Posted: 31 Oct 2016 05:43 PM PDT The numbers would take the form of: a2 + b2 = c2 + d2 I was playing with some numbers and found that squares of 11 generate this pattern often: 112 + 22 = 102 + 52 112 + 32 = 72 + 92 112 + 72 = 132 + 12 112 + 82 = 132 + 42 112 + 102 = 142 + 52 112 + 122 = 162 + 32 112 + 132 = 172 + 12 112 + 162 = 192 + 42 112 + 172 = 192 + 72 112 + 182 = 212 + 22 112 + 232 = 252 + 52 = 172 + 192 112 + 242 = 162 + 212 112 + 272 = 292 + 32 = 152 + 252 112 + 282 = 292 + 82 112 + 292 = 312 + 12 I'm guessing that these are similar to Pythagorean numbers and that there are an infinite number of them. Just the frequency it appears with 11 seemed interesting. [link] [comments]  |

| Posted: 31 Oct 2016 05:31 PM PDT A different way to phrase the second question: Can we find planets without a star nearby to provide some sort of light to detect it with? [link] [comments]  |
| [Physics] Why did Madame Wu use Cobalt-60 in the parity symmetry violation experiment? Posted: 31 Oct 2016 08:44 PM PDT Why, of all elements (and isotopes), was Cobalt-60 used and are there other elements that could have been used? [link] [comments]  |

| [Mathematics] Is there a mathematical proof for a relationship between n! and n^nth? Posted: 01 Nov 2016 02:12 AM PDT I was thinking about the two options, and how nnth should always be larger than n! for n>1, but I was unsure if the growth would fit into a simple equation. For instance, ( n!,nn . 2,4 . 6,27 . 24,256). Would I be right in guessing the first step of finding that relationship would involve dividing both by n? [link] [comments]  |
| How does an RNA 'know' which DNA strand to copy during transcription? Posted: 31 Oct 2016 03:55 PM PDT Since RNA is single stranded, and each base codon codes for an amino acid, what DNA strand is copied greatly influences the protein being formed. If both strands had the chance of being copied then you could have two proteins being coded by one gene. Proteins which could have vastly different functions. Is my understanding correct? Bonus question: Also, since you have two copies of each gene along each chromosome? what determines which chromosome is copied? [link] [comments]  |

| Posted: 31 Oct 2016 10:14 AM PDT This question is inspired by this recently discovered planetary system. One planet has an orbital period of 27,000 years, and the other has an orbital period of just 11 hours! An 11-hour year seems incredibly fast. My question is whether such an immense speed affects what happens on the planet's surface. I'm wondering particularly about whether meteors are likely to hit it any harder, on average, than a planet that's orbiting more slowly. And a second (probably easier) question: would there be noticeable centrifugal forces on a planet orbiting it's sun that fast? Would this cause tidal forces, deformations, etc? [link] [comments]  |
| What physical/chemical property of a material decides if it will make a good superconductor? Posted: 31 Oct 2016 12:37 PM PDT For example I know certain ceramics make better superconductors (i.e. they exhibit the effect at higher temperatures) than any metals. Why is that? What property of a material decides whether it will undergo the Meissner effect? [link] [comments]  |
