| Posted: 11 Dec 2021 05:20 AM PST For example, Richard Feynmann has color synesthesia for numbers. Did seeing numbers as colors help him in any way to solve equations? How would that work? [link] [comments] |
| How can you estimate the temperature of an arc discharge in air generated through high-frequency AC? Posted: 10 Dec 2021 06:16 AM PST Hi everyone. I'm wondering if it is possible or if there are methods to estimate the temperature of a plasma generated from an high-frequency arc discharge in air, like arcs generated from an arc lighter. Would it be dependant on the frequency, the distance between the electrodes or other things? The closest thing I found is related to the concept of electron temperature, but I haven't found any clear way to compute it. Thanks for your help and have a nice day! Edit: it would be in order to build an arc furnace capable of reaching temperatures up to 2100°C, to melt corundum [link] [comments] |
| If I put two things in the microwave instead of one, are they both going to be heated slower? Posted: 11 Dec 2021 03:14 AM PST The scenario is the following: I have a microwave that operates at 1000 W and I have two cups of water. I noticed that for the same amount of time spent in the microwave, a single cup of water will get warmer if it's in there alone. If I put both cups in there, I also habe to spend more time. So is the power being "shared" by the cups, and if so, do they share this power based on volume / mass / position? Do both cups of water receive 500 W each? [link] [comments] |
| Are natural diamonds really pretty common on earth? Posted: 11 Dec 2021 02:15 AM PST I have often read (also in this subreddit) that non-artifical diamonds are not rare on earth, and that the scarcity is only a result of the DeBeers Monopoly on the diamond market. Is this true? How common are diamonds in rock layers, where they are lucrative for extraction (and useful for jewelry production)? [link] [comments] |
| How did the salmon's life cycle evolve? Posted: 11 Dec 2021 02:44 AM PST How did these fish evolve to travel such incredible distances and endure such hardships for a complicated system of reproduction evolve, and why did it evolve this way? What is the advantage of such a system? [link] [comments] |
| Posted: 11 Dec 2021 04:43 AM PST The consensus seems to be that extroversion and introversion are at least in part inherited (similar question here), however I couldn't find information on whether or not these are recessive or dominant genes, or which chromosomes are responsible for the trait. Going from there, I also wondered if introversion and extroversion have any relevant impact on birthrates. If one of them had a lower chance to be passed on, then I would assume that the trait will eventually be lost. [link] [comments] |
| Posted: 11 Dec 2021 12:29 AM PST I've seen this claim a lot, but I just can't understand it. If I'm lifting a heavy object, then the force produced by the muscles must be greater than the weight of the object (concentric). If I'm holding it stationary (isometric) then the forces must be equal. If I'm lowering it slowly then the weight must be greater than the force produced by the muscle (eccentric). This means that the concentric contraction should be the strongest, and eccentric should be the weakest, but I keep hearing it the other way around. [link] [comments] |

| Posted: 11 Dec 2021 05:11 AM PST Is there any influence of magnetic property on Gibbs free energy equation? Can the magnetic domain alignment be taken into consideration for entropy? Higher the disorder of alignment, FCC (paramagnetic) is not stable at room temperature, is the reason behind this is the magnetic influence ? [link] [comments] |

| What do we know about the incubation period omicron variant? Posted: 11 Dec 2021 02:55 AM PST I've seen that the cases from Hongkong had repeatedly negative results and a positive result with a very high viral load very shortly afterward. How soon after exposure should one then get tested to avoid false negative? [link] [comments] |
| Does clove oil fumes harm longevity of oil paintings? Posted: 11 Dec 2021 02:53 AM PST I encountered some artist group claiming that eugenol and other chemicals from clove oil will evaporate and seep into oil paint. Some oil paints are quite expensive and a lot of people use it to slow the drying. I keep my palette and cotton balls with clove oil in it within an airtight container, without adding any clove oil in the oil paint directly. Will this damage the film formation process for oil paintings later? These artist claimed that Smithsonian conservationists stated that clove oil is bad for repairing paint films later. This might be a physics and chemistry mixed question [link] [comments] |
| Why total solar eclipses occur with more frequency in some countries/regions than in others? Posted: 11 Dec 2021 02:26 AM PST Hi! Out of curiosity I was checking out the list of total solar eclipses for this century and I noticed something: During this century a country like Argentina (South America) will have a total of 7 total solar eclipses while a country like El Salvador (Central America) won't have a single one In fact while Argentina will have as many as 7 during a period of 100 years El Salvador had a total solar eclipse in 1991 and will have onother one until 2132 after more than 100 years And I noticed that it seems that total solar eclipses are more common in some regions than others, for Example Australia or South America or even Antarctica will have more than 4 while regions like Central America won't have any. Why? Does earth's position has something to do? Or is it just a coincidence? [link] [comments] |

| What are some species that hunt Enypniastes? Posted: 11 Dec 2021 01:30 AM PST So, I recently started watching the new Welcome To Earth documentary series and it features the sea cucumber species Enypniastes eximia. Does anyone know what preys on enypniastes in the deep ocean? [link] [comments] |
| Posted: 10 Dec 2021 11:41 AM PST I don't know where I've got this thought process from, but I think I learnt that the brain maps the 'yin and yang' of creative logical in a much messier way than simply left right? What is the current understanding of the brains functioning areas please? [link] [comments] |
| What is the relationship between the size of an animal's brain and how smart it is? Posted: 10 Dec 2021 08:23 PM PST I saw a video of a spider and it looked smarter than just instincts so i was wondering how big their brains were and how much information is there and how much they can process. Also, what about animals which are larger than humans? how big are their brains and what are they capable of? Why did humans brains develop towards where we are now? Is there a ranking of animals which are the smartest (at least from what we know so far)? or at least which animals are really good at communication? [link] [comments] |

| Is a positive mindset beneficial for recovery from sickness? Posted: 10 Dec 2021 01:38 PM PST My sister is a nurse and told me that if you're mentally depressed because of your illness (Covid, Cancer, Flu etc.) that you're actually slowing down your bodies recovery and its ability to defend itself. Is her statement rooted in science? Because I know that if you're depressed your cognitive performance can decrease. So do parallels exist there? [link] [comments] |

| Why do we see stars instantly in a mirror? Posted: 11 Dec 2021 05:47 AM PST I was recently studying some very basic optics about plane mirrors. The most fundamental rule of image formation in a plane mirror is that the image distance from the mirror is equal to the object's distance from the mirror. Does that not mean that light has to travel that much distance inside the mirror? If the stars we see in the sky, are light years away from us, then light should take years to reach that distance inside the mirror. So how does the image appear instantly in the mirror?

| What is the longest vertical limit that capillary action can travel? Posted: 10 Dec 2021 10:50 AM PST Could something that transfers water through capillary action[a rope, cloth, or whatever else is better at this] theoretically be attached to a balloon a mile high and still raise water from whatever body of water the lower end is submerged in?
