| Can you orbit a torus by moving in a figure-eight, through the center? Posted: 28 Nov 2015 10:31 PM PST Two lobes of a figure 8, each encircling one side of the torus. Can this orbit exist? Of course a torus would never naturally form, but let's just ignore that bit :) [link] [5 comments]  |

| Is there a fundamental constant that all other constants are based on? Posted: 29 Nov 2015 05:46 AM PST I'm curious to know if there is one single constant that all other constants can really be derived from. A) If so, is that constant always the same no matter what? For example, if it is measured in a vacuum vs. in a black hole. B) If no, how many basic constants are there? And why is it that we cannot derive one constant from another? [link] [5 comments]  |

| Why does multiplying width by height yield area? Posted: 28 Nov 2015 10:53 PM PST I've taken linear algebra but I don't think I understand this. It's a completely serious question. edit: should have specified which shape I'm talking about (rectangle) [link] [8 comments]  |

| What exactly is the sine function? What does it do to the number in the brackets? Posted: 28 Nov 2015 12:34 PM PST I understand that a sine wave represents the relationship between the Cartesian coordinates of a point on a circle's edge, and the angle of the point. I know that, by combining a sine and cosine wave, you can draw a circle. I know the whole reason the sine wave is shaped that way is because a circular curve first drops slowly at the top of the circle, then very steeply, then slowly again. And from what I understand; in maths and programming, a function is just a set of instructions. It's short-hand for a list of operations to be performed on whatever you put in the brackets. What are these instructions for the sine function? Is it complicated? I suspect it somehow involves Pi or e or some other crazy number. Or - on a computer - does the sine function actually just reference a pre-made curve of data representing a sine wave? [link] [31 comments]  |

| Posted: 28 Nov 2015 11:03 PM PST A thought occurred to me as I was up having insomnia. I watched probably cosmos, and he said something along the lines of "adromeda is moving closer to us and by the year 6 billion, the two black holes in the center of both galaxies will collide, and anything that was living will die." So if the galaxy moves, the black hole moves, and it's not just the universe expanding, or else adromeda wouldn't collide with the milky way. So they do move, but how? [link] [3 comments]  |

| Effects of glyphosate on rhizosphere? Posted: 28 Nov 2015 07:38 AM PST I recently got into an argument where I was defending GMO's, and while following up with evidence and sources, I thought to myself - since anti-GMO arguments tend to feed a lot on pathos than reality - what actual empirical evidence does the anti-GMO crowd have to draw on? In the process, I came across this NYT article from 2013 about the detrimental effects of glyphosate on soil (and yes, I know that GMO != glyphosate), which draws its empirical evidence largely entirely from Robert Kremer's work on glyphosate. His paper Glyphosate and glyphosate-resistant crop interactions with rhizosphere microorganisms seems to capture the substance of his work well:
Wikipedia seems to describe Fusarium as a benign, commonplace fungus (and of course, too much of something can still be a bad thing; also, it was a strain of Fusarium that almost wiped out bananas in the 1800's, if I'm not mistaken), and the paper's introduction notes increased susceptibility to Phytophtora, which Wikipedia tells me is significantly more dangerous, but honestly, if I've learned anything during my time at university so far, it's that if I have to Wikipedia stuff even just once while reading a paper, then I don't know enough to fully understand it. Moreover, I couldn't really find anything responding to Kremer's work (the USDA work referenced in the NYT article sort of sidesteps the issue - understandable given the sizeable literature). Hence my question: how significant are these findings, really? Is glyphosate actually as threatening of an ecological risk as Kremer make it out to be, and how much actual support does his work offer to anti-GMO activists? [link] [6 comments]  |
| Does music affect brain development? Posted: 28 Nov 2015 04:46 AM PST I've heard of this claim before, especially in regards to classical music and childhood. Is there any truth to it? Does it vary by genre of music listened? Does it affect children and adults differently? [link] [1 comment]  |
| Why is it easier to remember a song than it is to remember the same lyrics without music? Posted: 28 Nov 2015 04:22 AM PST I was in the car listening to a song on the radio I hadn't heard in a year or so, and realised how easy it was for me to recollect the lyrics despite never explicitly learning any of them. I mean, learning the melody and rhythm of the music should make it more difficult, since you're learning two things (music and lyrics) instead of just one (lyrics only). So why is it easier to remember and recollect something as a song? [link] [3 comments]  |
