| How does your brain know which of your memories are real and which aren’t? Posted: 31 Aug 2019 03:54 AM PDT I'm laying in bed and just woke up from a dream where I placed an order for a new dining table. After I woke up from my dream it took a little bit of time for me to realize that I never actually ordered that dining table. How does my brain know my "dream memory" of me ordering that table didn't actually happen? [link] [comments]  |
| How did carbon enter the ecosystem? Posted: 31 Aug 2019 03:21 AM PDT So there's a bunch of CO2 in the atmosphere, there's oodles of coal and oil under ground, and there's a lot of trees built by carbon. But all that is just a cycle CO2 -> wood -> coal/ top soil nutrients. Also fauna will eat plant matter. But how did it all start? Was there some single celled organism munching on graphite or something? [link] [comments]  |

| Does the praying mantis actually hypnotize its prey; and if not, where does the rumor come from? Posted: 30 Aug 2019 11:58 PM PDT I'd genuinely like to know. I've personally seen them do this kind of thing to other insects. Is it just intimidation? Pheromones? An urban legend? [link] [comments]  |
| Posted: 30 Aug 2019 11:19 PM PDT I read on articles before that this theory, along with others during the age of New Global Tectonics, were once dismissed by academics. Also, Harry Hess' paper on seafloor spreading seem to confirm this by saying the same studies as "radical". If so, what did people think of the Earth back then? [link] [comments]  |
| Posted: 31 Aug 2019 01:51 AM PDT So with the increase in temperature, the number of ions increase due to increased dissociation and the motility of ions also increases. Hence, the conductance of the solution increases with the increase in temperature but when and how does the conductance becomes constant? [link] [comments]  |
| Why were Carbon Dioxide levels so high in the Mid-Pliocene? Posted: 31 Aug 2019 01:19 AM PDT I have been reading about the recent findings of evidence for past high-level sea rise. A link to the main article I am referring to is here: https://phys.org/news/2019-08-scientists-evidence-high-level-sea.html This high level sea rise, they explain, aligns with the Carbon Dioxide levels of the Mid-Pliocene. The CO2 levels during this period, USF Department of Geosciences Professor Bogdan Onac explains, were, "the last time the Earth's atmospheric CO2 was as high as today". Upon further research, I wasn't able to find a reason for why these levels were so high at this time in the Earth's history. What caused CO2 levels to get this high 3 million years ago? It wasn't as rapid of a rise in CO2 as there has been in the post-indusrial era, right? Perhaps the reason is insanely technical, or unknown, but either way I would love to know. I may have gotten some of this info incorrect, as I'm not terribly educated in this sort of thing. Feel free to correct me! [link] [comments]  |

| Why do whales breach? Is it to draw attention to themselves or to a certain area? Posted: 30 Aug 2019 08:29 AM PDT I never understood why they do that. It just seems like it takes a lot of effort on their part to do a "bellyflop" [link] [comments]  |
| Posted: 30 Aug 2019 04:55 PM PDT Say humans evolved to have 12 fingers and our entire system of maths and physics was based around base 12, like my brain ceases up when trying to think about this stuff but wouldn't it have a major impact on how maths developed in the first place? for instance obviously physical laws would stay the same but now the numbers and constants would be different to us, would that even have an impact at all or am I just confused because I can't get my head around it?

| Why do scabs itch so much before they're ready to come off? Posted: 30 Aug 2019 10:43 PM PDT We've probably all experienced as a kid picking at an itchy scab and re-opening the boo-boo before it's healed. I am currently fighting this urge right now! Why does it itch so much when it isn't even ready to come off? [link] [comments]  |
| How could a clock run backwards? Posted: 30 Aug 2019 06:48 PM PDT So I just remembered when I was in 5th or 6th grade while I was typing something (can't remember, and it's not important) the clock in the room was running backwards several times faster than normal. You could hear it ticking fast too. It was noticed halfway through the class and shortly after the teacher took it down from the wall because everyone was distracted by it. Anyway does anyone know how this could happen. I'm fairly certain the clock was battery powered but the memory is kind of faint. [link] [comments]  |

| How do the doctors figure out a prescription for baby glasses? Posted: 30 Aug 2019 08:39 AM PDT I've seen a lot of videos of babies getting glasses. How do the doctors figure out what prescription the baby needs? As an adult, there's a lot of guess and check in getting my prescription right, and they need continuous feedback from me. Is it a less exact prescription for babies? I know the machines they use before the guess-and-check get the prescription somewhere close. [link] [comments]  |
| Does how much water flows through a filter affect how well it works? Posted: 30 Aug 2019 06:29 PM PDT When I was younger we got a faucet filter, and my dad used to say if you put the water on full blast it wouldn't filter as well. [link] [comments]  |
