| What actually determines the half-time of a radioactive isotope? Posted: 03 Dec 2018 03:45 AM PST Do we actually know what determines the half-time of a radioactive isotope? I tried to ask my natural science teacher this question, but he could not answer it. Why is it that the half-time of for an example Radium-226 is 1600 years, while the half-time for Uranium-238 is 4.5 billion years? Do we actually know the factors that makes the half-time of a specific isotope? Or is this just a "known unknown" in natural science? [link] [comments]  |
| What was the Amazon like when the Sahara was still green? Posted: 02 Dec 2018 09:12 AM PST The sandstorms from the Sahara are cited as a contributing factor to how big the Amazon is because of all the mineral nutrients that are carried in the sand to Amazon soil (and North American soil as well). Well what was the region like a few thousand years ago when those sandstorms weren't happening? Was it it's own dessert? Or did the Amazon river support a river plain like the Mississippi River basin in the US and Canada? [link] [comments]  |
| Posted: 02 Dec 2018 10:43 AM PST I once read in one of those CWF Wild magazines years ago that bugs cant feel pain because their nervous system is too small. Does anyone know if this is true, and if so what causes it? [link] [comments]  |

| How do complex mutations happen through evolution? Posted: 02 Dec 2018 11:15 AM PST How do extremely complex organs come to exist through mutations? I don't think that a single mutation could cause something as complex as eyes to exist but it's also hard to believe that a small mutation like the beginning of eyes would be valuable enough for natural selection to create a large enough population of it for it to mutate again.

| Optics question: What are the lines of light in clear water called? Posted: 02 Dec 2018 12:58 PM PST For instance, the lines of light that are reflected in this photograph. [Imgur](https://i.imgur.com/KGeDZR5.jpg) [link] [comments]  |

| What would happen gravitationally if Earth where surrounded by a hollow sphere? Posted: 02 Dec 2018 02:42 PM PST Based on Newtonian Gravity/Newton's Shell Theorem the gravity caused by they sphere would be zero inside, so would Earth just drift within the sphere? [link] [comments]  |

| Why is quantum entanglement so important to quantum computing? Posted: 02 Dec 2018 10:05 AM PST I understand that superposition allows for multiple operations to go on at once, and I understand quantum entanglement. I keep reading that entanglement is involved in quantum computing but I cant find a definitive answer as to how it actually helps. Thanks in advance for your help :) [link] [comments]  |
| What makes one particular material good at dampening sound versus another material? Posted: 02 Dec 2018 10:13 AM PST I'm sure it's more than a function of material density. Is there a metric for a materials ability to convert acoustic waves to phonons which permit photonic emission? [link] [comments]  |

| Posted: 02 Dec 2018 09:41 AM PST It is my understanding that a heart attack is caused by plaque build up in the coronary arteries. Correct? Why do we never hear about obstructions in other vessels? What is it about the vessels of the heart that make them more prone to obstruction? [link] [comments]  |

| Posted: 02 Dec 2018 03:39 AM PST Very recently I was ill and being sick every couple hours. But after a couple times I was just dry heaving as I had nothing left in my stomach. I'm wondering why my body couldn't tell my stomach was empty and kept trying in vain to throw something up. [link] [comments]  |
| Posted: 02 Dec 2018 08:16 AM PST Down's syndrome is trisomy, a chromosomal separation error in Meiosis. Because it is more common in older mothers I imagine the trisomy comes in the egg. But if eggs are ready at birth, how do the eggs with trisomy come later in life? Are the egg cells "set aside and ready" at birth but actually experience Meiosis close to ovulation?
