| Posted: 26 Jun 2022 07:20 PM PDT For example, in terms of stability, what's stopping a hydrogen atom from filling up its 2s orbital and remaining that way? [link] [comments] |
| Are there any retroviruses that infect bacteria? Posted: 26 Jun 2022 06:10 PM PDT I'm wondering if there are any RNA viruses that infect bacteria. All of the examples I know infect eukaryotes. [link] [comments] |
| Why is there a window in the absorption spectrum of Earth's atmosphere at a wavelength of 4 μm? Posted: 26 Jun 2022 07:17 PM PDT Looking at the Wikipedia page for absorption bands, it seems to me that there's a sizable window - i.e. a local minimum - in the graph for electromagnetic radiation absorption, as per this image. Water vapor, oxygen, ozone, and methane appear to be entirely transparent to radiation of 4 μm wavelength, carbon dioxide only appears to start absorbing it after that point, and even nitrous oxide has a window there. Moreover, Rayleigh scattering is also minimal there. On top of that, this Earth Science Stack Exchange answer and its source show minimal (sub-0.5%) absorbance of sulfur dioxide at that wavelength. Why is this? It seems like a rather odd coincidence for so many things to be transparent to 4 μm (a specific wavelength of mid-wavelength infrared) EM radiation. As a coincidence, this is one of many parts why global warming is a thing, IIRC: mid-range infrared comes in through the 4 μm gap, gets soaked up by the Earth, and later gets re-radiated at different wavelengths that do get soaked up by the atmosphere. I just don't know why there's a 4 μm gap there. [link] [comments] |
| Would there be any treatment for radium poisoning if it happened today? Posted: 26 Jun 2022 06:52 PM PDT Just finished reading Radium Girls which is about girls in the 1920s who painted watch details using radium-laced paint, essentially ate the paint as part of the painting process, and then developed horrific effects in their bones, especially jaws. There was pretty much no treatment at the time, and I know that even in today there aren't many options to treat radiation sickness from like an attack, but would there be anything that could be done for cases like these? They lived in horrific pain for years after they more or less knew what was going on, making multiple women understandably suicidal. [link] [comments] |

| Where did the parietal eye originate? Posted: 26 Jun 2022 07:09 PM PDT Was there just a third patch if photoreceptive cells on the head of ancestral craniates, or is it more complex? Could this have theoretically evolved into a third "proper" eye? [link] [comments] |
| Posted: 26 Jun 2022 12:46 PM PDT Solar panel sun tracking is why I ask. There are active trackers which use light sensors to change the angle of solar panels in order to maximize their efficiency. As an alternative if setting up a panel at a particular location, that locations position variables could be set statically and using date and time point the solar panel toward the predicted location of the sun in the sky. I'm wondering if those functions/equations already exist. [link] [comments] |

| What is the slowest speed of movement a human eye/brain can perceive? Posted: 26 Jun 2022 03:45 PM PDT We can see something like a snail move across the sidewalk but don't really notice something like a leaf growing. What is slow but fast enough for us to observe while watching it? [link] [comments] |

| At what depth is the water table considered to be “low” or “high”? Posted: 26 Jun 2022 08:55 PM PDT I recently had a soil scientist test the soil on my new property. His report states that the soil classification is "sandy mixed mesic typic udipsamments." The parent material is "glacial outwash." The depth of the seasonal water table is ~60", depending on the location of the bore sample. It also states that the depth of the dense basal till is >65". Can someone explain this all to me? Also, do I have a high or low water table, based on this info? [link] [comments] |

| What makes light able to pass through solid transparent materials? Posted: 26 Jun 2022 01:28 PM PDT You could have a foot of solid glass and light will still traverse through it, and yet a thin sheet of paper will block most of it. [link] [comments] |
