| What do they mean by the activity of ammonia is lower at low temperature? Posted: 28 Dec 2019 08:25 PM PST On the Hach website, they say ammonia-ammonium equilibrium shifts towards ammonia as pH and temperature increases. I understand the pH part, but how does temperature affect this equilibrium? What do they mean by " lower or higher activity of ammonia"? [link] [comments]  |
| What objects has Pluto "failed to clear", and why has it failed to do so? Posted: 29 Dec 2019 05:26 AM PST Is the issue that it's so far from the sun and has such a massive orbit that it has not yet had time to clear all the asteroids and clutter that share a similar orbit? Given more time, is it likely inevitable that Pluto will become a planet? How many objects (roughly or precisely) does it have left to clear? Are they numbered/named? Is Pluto large enough to do so and simply hasn't, or is Pluto lacking some attribute (size/density/mass) that is causing it to fail to clear its orbit? What's the largest object that it shares orbit with? [link] [comments]  |
| What would happen if one were to build a canal linking two rivers flowing in opposite directions? Posted: 28 Dec 2019 08:46 AM PST Would the one with the stronger stream push the other? Would a lake be formed? [link] [comments]  |
| Can some explain geologic province? Posted: 28 Dec 2019 06:41 PM PST So I was world building and then I stumble on geologic province. So I look at the Wikipedia page and other websites and I still don't get it. [link] [comments]  |
| What are the most popular theories for the origin of Supermassive-Blackholes? Posted: 28 Dec 2019 09:49 AM PST I may be wrong, but I dont think I've came across an answer to this. My physics teacher told me in school that they were "just incredibly greedy blackholes that got larger over billions of years". But I always just found that answer extremely improbable. I just don't see how a normal stellar-mass blackhole could possibly become supermassive even over billions of years to accumulate matter. I've always had the idea (im no physicist) that SMBHs are almost as old as the universe itself, and were created back when the universe was still extremely dense in the early universe - allowing for an extremely concentrated area of mass for any blackhole to feed on. And as the universe expanded, these SMBHs became the anchors which much of the matter clinged to - eventually becoming galaxies. But that was just my idea as a kid. For real though, are there any new or promising research-teams looking into their origin? Thanks in advance. [link] [comments]  |

| Do we subconsciously absorb things we are hearing but not listening to? Posted: 28 Dec 2019 12:24 AM PST Like is all of that sort of memory stored in the same way we would see faces of people in our dreams we don't at all recognize, but they just happen to be one of the hundreds of people we've seen at a glance in crowds just logged into our memory. Ik, kinda dumb question because it's probably obvious but what got me thinking about this was this old story: https://www.google.com/amp/s/www.dailymail.co.uk/news/article-2740708/amp/Aussie-man-wakes-coma-car-crash-speaking-MANDARIN.html It's about a guy who had a brain injury from a car crash and woke up only speaking fluent Mandarin. The skill had came from what classes he had taken in school but never truly or fluently took with him after graduation, yknow like most people. Wondering if our brains indeed just absorbs 100% of everything we experience but just cannot unlock them. [link] [comments]  |
| Posted: 28 Dec 2019 01:48 PM PST According to the english Wikipedia, a desert is an "area of Landscape where little precipitation occurs". According to the german Wikipedia, a desert is defined by the lack of vegetation. I feel like the definition by absence of vegetation makes more sense since it includes areas under water. Edith: Desert, not Dessert. [link] [comments]  |
| What is the physical memory of the brain encoded in and how does it work? Posted: 27 Dec 2019 08:47 PM PST I am curious to what the physical memory of the brain is encoded in. Computer images are done in Base 16 and data is transferred in base 2. How in the world does the brain store its information? How is it organized? How come I have the inability to just scan through my memory? I can listen to a small part of a song and tell you what song it is from for tons of songs. However, I couldn't play back a single song from start to finish in my brain after hearing it multiple times. [link] [comments]  |
| Why don't bears muscles atrophy when they hibernate? Posted: 27 Dec 2019 03:36 PM PST Like when people are bedridden or in a coma their muscles atrophy and we have to build them back up. Do bears go through the same processes after winter ends? [link] [comments]  |
