| How is the original amount of C14 in a fossil determined? Posted: 23 Jul 2018 12:49 AM PDT When it comes to carbon dating, I understand how the age of a fossil can be determined with the necessary information, being how much C14 is in the current fossil, how fast that C14 deteriorates, and the original amount of C14 in the animal. My question is how the original amount of C14 is determined? Looked everywhere I could and couldn't find an answer, so thank you for any replies. [link] [comments]  |

These questions come from my thinking that a goat fainting in the wild would be a huge disadvantage. Of course, this might be a result of domestication? Any insight for my pure curiosity is appreciated. :) [link] [comments]  |
| How does the Mars atmosphere sustain the current wind and dust storms? Posted: 22 Jul 2018 09:57 AM PDT So recently there have been planet wide wind storms on Mars. I looked up some information about Mars' atmosphere and saw that it has 0.6% of the pressure Earth has at sea level. If this is true how is there enough of a pressure difference in the atmosphere on Mars to produce winds strong enough and for a great enough periods of time that a planet wide storm is born that literally shapes the way the surface looks.

| Is it possible to harness energy from sound waves? Posted: 22 Jul 2018 02:05 PM PDT Hi, I hope I don't sound stupid asking this question. Is it possible to harness energy through sound waves? They're vibrations which is a form of energy, right? [link] [comments]  |

| Are tide heights affected by the time of day? Posted: 22 Jul 2018 01:22 PM PDT I live in a coastal town and it always seems that a high tide is a lot higher when it occurs in the evening/night as opposed to in the day. Is this just coincidence or is there something else causing this? [link] [comments]  |

| Posted: 22 Jul 2018 08:46 AM PDT It seems like there's been a number of claims, like this and a recent YouTube video out there that gold gets its color due to special relativity and the effect it has on atomic orbitals. This claim seems to relate back to this work on some gold-based molecules in a fluid. It's also appears in wikipedia here. However, the reflection spectra of atomic gases are entirely different than atomic solids and often atomic spectral lines have no connection to the way a solid reflects light. The reason for metallic reflectivity is due to plasma oscillations and is a general property of a free-electron gas. Furthermore, looking at the reflectivity of gold and other metals, it's pretty clear that you don't have a sharp peak, like in atomic absorption lines, but a cut-off where all energies above it are not reflected (like a plasma frequency cut-off). So are these claims about metallic gold getting its color from relativistic effects (i.e. atomic spectra) a bunch of bunk? Or is the plasma frequency of gold related to its absorption spectra in some subtle way that makes such a claim valid? [link] [comments]  |

| Posted: 22 Jul 2018 06:41 AM PDT Was just thinking about how data is stored, and how it might be more efficient. Any work or reading someone could direct me to understanding that more would be appreciated. [link] [comments]  |
