Are planetary rings always over the planet's equator? Posted: 19 Oct 2021 09:16 AM PDT I understand that the position relates to the cloud\disk from which planets and their rings typically form, but are there other mechanisms of ring formation that could result in their being at different latitudes or at different angles? submitted by /u/BrStFr [link] [comments]

The number of colours a human can distinguish is estimated to be in the range of 1e6 to 1e7, how is this range estimated? Posted: 19 Oct 2021 11:49 PM PDT Any citations would be helpful, thanks :)!! submitted by /u/fool126 [link] [comments]

Why are the seatbelts on cars, buses, and airplanes different? Posted: 19 Oct 2021 03:58 AM PDT More specifically, why does a bus use the fiddly two point seatbelt that takes forever to adjust? It's not as secure as the three point car seatbelt, and it's not as easily adjustable and removable as a airplane seatbelt. submitted by /u/Lithrops [link] [comments]

How can you identify if an atom can make 5 or 6 bonds in a molecule? Posted: 19 Oct 2021 10:21 PM PDT I'm an 11th grader and I'm really confused on which atoms can make more than 4 bonds. For example in the class work there's a question that asks the structure of xenon tetrafluoride and my chemistry teacher said it can go up to 12 electrons. I understand that hybridization has something to do with it, but my teacher didn't explain it well. submitted by /u/Coyomo [link] [comments]

Spontaneous combustion and volatile organic compounds? Posted: 19 Oct 2021 08:02 PM PDT I just saw this post on a different subreddit. A guy is stepping out of a truck and the air around suddenly explodes. In the comments someone said it's vocs caused by the plastic, still not entirely sure what that is either. but If that's the case how come every time you open a shipping box nothing just explodes. https://www.reddit.com/r/blackmagicfuckery/comments/qb9lod/spontaneous_combustion/?utm_source=share&utm_medium=mweb. submitted by /u/banana_funk [link] [comments]

How does the iron in heme get bleached? Posted: 19 Oct 2021 05:06 PM PDT I'm stuck in bed and went down an extraordinarily weird rabbithole. I found this video here where this guy successfully bleaches a test tube of his blood. How does this work? Can iron be bleached? Can anyone describe what's happening in greater detail? He doesn't really explain it in the video. Thanks :) submitted by /u/ShaughnDBL [link] [comments]

As we get COVID boosters, does our imune response indicate effectiveness? Posted: 19 Oct 2021 02:42 PM PDT Basically the title. Ask the boosters are coming out now and people are getting them, I'll hearing from friends about how strong this response is vs the past ones. I have had friends that had a mild, then strong, then no response and others that are none, mild, strong responses. There doesn't seem to be a pattern to it (not that there has too be). I guess the question is, does the strength of responses in relation to previous ones indicate anything about effectiveness or anti-body levels? submitted by /u/freedompancakes [link] [comments]

Are the COVID 3rd dose and booster shot identical? Posted: 19 Oct 2021 03:36 PM PDT All I can find online is a comparison of who should get which and when based on timing and medical history. I would like to know if the vaccines/shots themselves are both mRNA vaccines, are they both the same volume, if they are mRNA are the sequences identical? submitted by /u/BenCub3d [link] [comments]

How can chip manufacturers like Intel, AMD, and Apple keep giving huge improvements on performance every few months by changing the architecture? Posted: 18 Oct 2021 09:18 PM PDT I recently saw the comparison chart for the new M1X chips which give 50% improvement over the previous generation. I'm wondering if the semiconductor size remains the same and the die size is the same as well, then how can they manage to just keep changing the architecture every so often. If the architecture change takes so little time, then why don't all companies have the same performance? Is it just the chip architecture they change or is it something else as well? submitted by /u/DaasDaham [link] [comments]

Some wheels have an interlaced(cross) spoke design. The spokes curve slightly around each other. Would it be stronger to weld or fasten the spokes together where they cross? Posted: 19 Oct 2021 12:56 AM PDT Assuming that an ideal welding itself in no way created weakness at the spot of welding. Then the spokes could be straight instead of curved around each other at the point of crossing. submitted by /u/LettuceBeHappy2 [link] [comments]

"Apples new M1 Max chip is its most powerful yet, with 57 billion transistors" What does that actually mean, are they physical things or countable? Posted: 19 Oct 2021 02:13 AM PDT How do they make these or where does this number come from? How is anyone making 57 million of anything fit on something so small. submitted by /u/KiryusWhiteSuit [link] [comments]

How does adding texture to a surface reduce drag? Posted: 18 Oct 2021 03:43 PM PDT I saw that Airbus is trying to mimic shark skin's denticles to decrease drag, but I don't understand how something rough creates less drag than something smooth. How does this work? Is it similar to why a golf ball has dimples? submitted by /u/g3nerallycurious [link] [comments]

How would I give directions to earth? Posted: 18 Oct 2021 12:30 PM PDT Hypothetical. I wake up on an alien space station. We can communicate fine, and I judge them to be good people, no threat to humanity. But I need to get home. I know I'm in the Milky Way. I don't know how long I've been asleep. They know most of the galaxy by documentation of it's visable properties at minimum, but given specifics they can narrow their search. What information could I provide them, if any, to point them back to Sol? Or are things too much in motion to use anything as a reference? Thanks, submitted by /u/Jhtpo [link] [comments]

Questions about the stem cell therapy of the wilson disease? Posted: 19 Oct 2021 05:25 AM PDT I have a number of questions about the Stem cell therapy for the wilson disease. I tried to look into this myself, but i cant find much information about this. Any relevant sources and links would be very helpful. 1.What stem cells are used and how are they obtained? 2.Are the stem cells themselves inserted into the patient? Or are the stem cells cultured in a lab to become a certain type of specialised cell which is then inserted into the patient. Does the body have to be prepared in order to receive these cells? How are the cells inserted into the body? What stage of development is the treatment at? How effective is the method at treating the disease? submitted by /u/Dear-Friend-8628 [link] [comments]

Is there an upper limit to the highest possible bypass ratio of a turbofan engine? Posted: 19 Oct 2021 05:26 AM PDT I am not an engineer and only have an rudimentary understanding of the physics behind the jet engine, especially for commercial airliners. Admittedly, much of the physics behind why a high bypass ratio for commercial airliners is fuel efficiency was quite counter-intuitive for me, I.e slower compressor speed and more air directed to bypass duct means more thrust. Theoretically, how far high up can the bypass ratio be reached and what new technologies can enable greater fuel savings and greater range for jet engines? submitted by /u/RonaldYeothrowaway [link] [comments]

What does p-value really mean? Posted: 18 Oct 2021 12:36 PM PDT submitted by /u/knut_2 [link] [comments]

In stimulated emission, is the photon emitted in the same direction as the initial photon? Posted: 18 Oct 2021 08:22 AM PDT When an atom absorbs a photon, it will absorb its momentum as well and recoil in the direction which the photon was traveling. When an atom spontaneously emits a photon it will experience a recoil in the opposite of whatever direction the photon was randomly emitted in. What about stimulated emission? Will the newly stimulated photon be emitted in the same direction as the initial photon (thus giving the atom a recoil in the opposite direction of the initial photon direction), or will the stimulated photon go in a random direction (or is there a more complicated probability distribution over which direction the stimulated photon is emitted)? submitted by /u/timelesssmidgen [link] [comments]

Effectiveness of Malaria Vaccine against different plasmodiums? Posted: 18 Oct 2021 08:57 PM PDT Exactly what the title asks. I haven't been able to find a lot of info about the efficacy of the Mosquirix (RTS, S) vaccine against different plasmodium species that cause malaria. Any Immunologists or Biologists who can answer this? submitted by /u/Erebus_Oneiros [link] [comments]

Why do people say that the expansion of the spacetime is accelerating if the Hubble sphere is expanding? Posted: 17 Oct 2021 05:59 PM PDT My understanding is this: The Hubble sphere is the distance from us at which spacetime (and the objects in it) are moving away from us at c. Assuming that the expansion of spacetime is constant, then that distance would also be constant. But, if the expansion of spacetime is accelerating, then the distance to space that is moving away at c would get closer to us over time, and thus the Hubble sphere would shrink. And if the Hubble sphere is instead expanding, that means that the expansion of spacetime is actually decelerating. But people say that the Hubble sphere is expanding AND that the expansion of spacetime is accelerating, which are completely contrary to each other. Is my understanding incorrect? Am I missing something? submitted by /u/danegraphics [link] [comments]

Why is my pot hydrophobic where it contacts the range grill? Posted: 18 Oct 2021 02:47 AM PDT pic of the pot pic of the range This is the pot in the sink after being washed and rinsed. You can see the water collects in a pattern that matches that of the range. The pot is steel, I imagine the range is as well. The bottom of the pot is flat. The pot is cool. submitted by /u/WhatisAleve [link] [comments]

How do electrical grids manage phase balance? Posted: 17 Oct 2021 11:25 AM PDT In the US most residences are fed by single phase power, usually via a split-phase transformer. Somewhere upstream of this transformer, presumably at a distribution substation, that single phase is being drawn from a three phase transformer. So what mechanism is used to maintain phase balance? Do you just make sure each phase supplies about the same amount of households and hope for the best or is it more complex than that? submitted by /u/not_a_novel_account [link] [comments]

How long do the fissile materials in nuclear bombs remain active enough to detonate? Posted: 17 Oct 2021 10:44 PM PDT I just had a thought that Fallout has enough crazy people to see more bombs go off. I'm sure the electronics and infrastructure needed to deploy them will degrade much faster, but how long would it be before the fissile material in leftover weapons would deteriorate? submitted by /u/ThePremiumSaber [link] [comments]

Jet Engine vs Rocket Engine?

What’s makes a gene dominant or recessive? And how does it work? Posted: 17 Oct 2021 08:21 AM PDT Why does the blue eye gene not show when a brown eye gene is present. Does the brown eye gene delete the blue eye gene, or does it override it, does the blue eye gene just become inactive? If it does become inactive why? submitted by /u/Suspicious_Role5912 [link] [comments]

How long does it take for oxygen in your body to cycle? Posted: 17 Oct 2021 06:47 AM PDT You breathe in oxygen, it gets attached to hemoglobin, which delivers it to cells where it gets used by cells to generate ATP, producing carbon dioxide, which gets pumped out of the blood by that same hemoglobin and dumped back in the lungs. How long does this cycle take? E.g. if you were to breathe in some oxygen 17, how long would it take for it to exit your body? Similar question in regards to water that you drink - how long does that cycle take from absorption to excretion? submitted by /u/melmonella [link] [comments]

Can dolphins really do arithmetic operations? Posted: 16 Oct 2021 10:40 PM PDT I went to a local safari park and part of the educational shows that they have there is dolphin shows where they show off what dolphins can do like how they make sounds to communicate to each other, doing flips and such. Among the tricks was they asked a member of the audience to provide an arithmetical operations (additions, subtractions, multiplications, divisions) with the limitation that the results should be 1 to 10. The trainers will then write the operation on a small blackboard, point it out to the dolphin and the dolphin will swim around and splash their horizontal fins as many times as the answer. The audience will count along with the number of splashes. There's usually two math problems presented to different dolphins. The first doplhin usually gets the answer right, while the second one fails at the first attempt then gets the correct answer at the second attempt. So does the dolphin really read the blackboard and actually did the arithmetic operations or its actually looking/listening to other cues from the trainers? submitted by /u/duck_duckone [link] [comments]

How do we feel electricity? Posted: 16 Oct 2021 03:09 PM PDT This might be a dumb question, but the keywords involved make it hard to Google for an answer because "electrical", "shock", "nerve", and "nociceptor" connect to a lot of subjects. So what's the mechanism for feeling an electrical shock? Humans have dedicated mechanisms for perceiving mechanical, thermal, and chemical stimuli, and presumably electrical shock is just hijacking one of those, but which one? Or all of them? Or something else? submitted by /u/not_a_novel_account [link] [comments]

What is the phenomenon behind the arrangement of the large North American lakes? Posted: 15 Oct 2021 01:49 PM PDT I was looking at a map of North America and noticed in addition to the more recognizable Great Lakes, you can draw a sort of line/curve all the way from the great bear lake in the northwest of Canada all the way to Lake Ontario, including all the major lakes in between. Not only can you draw this curve, it also aligns somewhat with the Canadian Shield. Is this coincidence or was there some prehistoric geological process that caused these lakes to align this way? submitted by /u/mannisbaratheon97 [link] [comments]

Why does increased dead space ventilation increase alveolar PCO2? Posted: 15 Oct 2021 04:17 PM PDT So I'm watching a video on alveolar ventilation and dead space. I am having a hard time working out why an INCREASE in dead space ventilation will increase PACO2. I know if you use the alveolar vent. equation, the numbers work out this way, but I am asking why this happens. Is my line of thinking correct here : Let's say occlusion happens to a Pulm. capillary, increasing dead space - no gas exchange can happen here, causing shunting to healthy alveoli. This will cause more gas exchange to happen at the healthy alveoli and result in more CO2 unloaded at these sites. Therefore causing the increase in PACO2 at the healthy alveoli? submitted by /u/pandaTap [link] [comments]

Why don't greenhouse gases reflect just as much incoming sunlight as they trap? Posted: 15 Oct 2021 05:22 PM PDT The common explanation of greenhouse gases is that sunlight that would bounce off the Earth out into space instead bounces off the greenhouse gas, trapping that heat on Earth. But if greenhouse gases simply reflect solar radiation, wouldn't they also reflect from the "outside", too, thus preventing solar radiation from reaching the Earth in the first place? submitted by /u/dahud [link] [comments]

If a persons brain is split into two hemispheres what would happen when trying to converse with the two hemispheres independently? For example asking what's your name, can you speak, can you see, can you hear, who are you... Posted: 14 Oct 2021 05:52 AM PDT Started thinking about this after watching this video: https://www.youtube.com/watch?v=wfYbgdo8e-8 It talks about the effects on a person after having a surgery to cut the bridge between the brains hemispheres to aid with seizures and presumably more. It shows experiments where for example both hemispheres are asked to pick their favourite colour, and they both pick differently. What I haven't been able to find is an experiment to try have a conversation with the non speaking hemisphere and understand if it is a separate consciousness, and what it controls/did control when the hemispheres were still connected. You wouldn't be able to do this though speech, but what about using cards with questions, and a pen and paper for responses for example? Has this been done, and if not, why not? Edit: Thanks everyone for all the answers, and recommendations of material to check out. Will definitely be looking into this more. The research by V. S. Ramachandran especially seems to cover the kinds of questions I was asking so double thanks to anyone who suggested his work. Cheers! submitted by /u/TwizAU [link] [comments]

By how much could we lower sea levels if we filled the Qattara Depression? Posted: 15 Oct 2021 02:57 AM PDT I am aware that rising sea levels aren't the only issue with our ongoin climate crisis, but I was wondering if filling large swaths of land (like the Qattara depression) would have a noticeable impact on sea levels. So assuming we build a canal and manage to fill it completely, would that have an impact on sea levels? submitted by /u/Psyman2 [link] [comments]

How come Lagrangian and Eulerian approches give different velocity expressions and magnitude if they represent the same object? Posted: 15 Oct 2021 04:22 AM PDT Lagrangian and Eulerian approches are both used to describe a body movement, but most of the time they give different velocity expressions and also magnitude: one could be zero and the other different than zero. How could this be possible given that they represent the same object in motion? submitted by /u/Pleasant_Delivery_68 [link] [comments]

How do you calculate energy losses in long distance power lines? Posted: 15 Oct 2021 03:52 AM PDT I've been looking in the concept of whitewashing a bit recently and came across articles mentioning companies buying electricity from power plants in other regions that require multiple stepup/down transformers. And Over 1000miles of Power lines combined. Is there a method to calculate this? Production -> 300 miles 400MVac mv -> 400mile 400MVac- >200miles of DC cable -> 400 miles 400KVAC -> 20/40 kv destination. I assume there is significant losses in a setup like this where power isn't brought from the nearby production facilities. I also know this isn't how the power grid works but it's the way that the green energy is defined. submitted by /u/memehunt3r [link] [comments]

Do the atomic subshells in a given shell have different average radii? Posted: 14 Oct 2021 11:03 PM PDT Forgive me - I never took P-Chem. It struck me that if the primary driver of difference between the shells was the principal quantum number (n), then the azimuthal quantum number didn't seem to explain the difference between the energies of subshells in the same shell (3d > 3p > 3s, e.g.) for the same reasons (where U = F * r), unless it is indeed the case that the increased number of electrons in that subshell caused a mutual repulsion which caused a net outward Force. submitted by /u/Kyrthis [link] [comments]

Were Henrietta Lacks’ cancer cells unique? Posted: 14 Oct 2021 12:12 PM PDT I read an article that said the cancer cells they collected from her without her consent were the first and only cells ever to have been found to multiply outside of the body. Is this correct? submitted by /u/v-a-g [link] [comments]

Can two people at different inertial frames (skewed light cones relative to each other) communicate information to each other about events outside of their respective light cones? Posted: 14 Oct 2021 10:49 AM PDT submitted by /u/ytman [link] [comments]

What keeps magnetic domains in alignment? Posted: 14 Oct 2021 10:22 AM PDT In the production of permanent magnets, it is known that heating the metal up and then slowly cooling it down in the presence of a large external magnetic field will align the domains and they will stay in line creating a permanent magnet. What is it that stops the domains from scattering after they are cooled down in the same way that the domains scatter after a normal piece of metal is removed from a magnetic field? submitted by /u/Affectionate_Flow682 [link] [comments]

Is the antibody concentration really a reliable factor to judge whether a person needs a third vaccine shot? Posted: 14 Oct 2021 12:51 PM PDT If the antibody concentration is not a reliable factor for measuring immunity against a certain disease, why is it used as an argument for a third booster vaccination against COVID? I keep reading in the media how the antibody concentration declines over time, and therefore we need to vaccinate especially vulnerable groups for a third time. But to my understanding, the antibody concentration will go down, no matter what. Won't it? submitted by /u/Willow1337 [link] [comments]

Is the power rating of a microwave oven (1100 watts for instance) the actual power the magnetron draws? If do doesn't this mean there can't be more or less efficient microwaves of the same cooking efficacy, barring overhead from control circuitry?

Where does the sugar in fruits come from after they become ripe? Posted: 14 Oct 2021 08:00 AM PDT When you go to the store to buy mangos or bananas they come unripe and they are mostly sour and are not very sweet, though after a week when they become ripe they are much more sweet than when they were unripe, my question is whqt happans that makes them so much more sweet? submitted by /u/yourboi6969420 [link] [comments]
