But is it the WHOLE time? like for example if I played a 24 hour podcast for a comatose person would they be aware the whole time? Or would they miss 8 or so hours of it because they were "sleeping"?

| Posted: 02 Feb 2022 11:25 AM PST I just read this New York Times article and, while I am very happy these new vaccines are in development, I had absolutely no idea there were different antibodies for different parts of your body / getting vaccinated in a different place could create different antibodies. What the hell? [link] [comments] |

| Regarding the incompressible flow assumption when applying the Navier-Stokes equations in CFD? Posted: 02 Feb 2022 11:17 AM PST Hello fellow curious minds! I've recently started studying the Navier-Stokes equations, aerodynamics and its application in CFD. From what I have understood, the Navier-Stokes equations are based on three fluid assumptions: - Newtonian (which I've understood the implications of) - Incompressible - Isothermal I am wondering how the incompressible assumption is regarded for when e.g. simulating an aircraft at some flight state, as air is compressible(not incompressible) in "reality". From what I've learnt, CFD (Ansys Fluent) is used in many aircraft applications for understanding the aircraft characteristics, is the impact of the incompressible fluid assumption small when it comes to the gathered results from the simulation(s), or how do engineers tackle this? I am also curious about the Isothermal assumption, as I have seen that there is an option for enabling heat transfer in Ansys Fluent. But the Isothermal assumption implies that there is no heat add/loss to the fluid as it flows, how is this incorporated/calculated within the CFD software? [link] [comments] |
| Why do aggregation-prone proteins need to be kept at -80C instead of -20C? Posted: 02 Feb 2022 08:50 PM PST Many protocols call for long-term protein storage at -80C. If a protein is immobilized in ice at -20C, why does the net 60C matter? [link] [comments] |
| Why don’t we ever hear about the amplitude of ionizing EM waves? Posted: 02 Feb 2022 03:46 PM PST I know that non-ionizing EM waves have a measurable amplitude. So why is the amplitude of ionizing EM radiation never defined? [link] [comments] |
| How rare is central heterochromia (having multiple colours within the eye)? Posted: 02 Feb 2022 02:12 PM PST I have this as do a few of my close family, I thought it was just a fairly common thing but it seems to be somewhat uncommon and a unique eye condition. My eyes are blue/grey with gold around the pupil. How rare is this condition? Like in terms of % of population? [link] [comments] |
| Is there any proven correlation between face structure and personality traits? Posted: 02 Feb 2022 03:55 PM PST I'm curious because in personal experience there's almost always a way to tell some personality traits (ex. funny, serious, egotistical, shy, etc.) from somebody just by looking at their faces, even if said person isn't doing a gesture (neutral). Sure, everyone has nuances, but I would like to know if there has been any study on the probability of this happening. [link] [comments] |
| Posted: 02 Feb 2022 03:24 PM PST The fraction of a percent of the atmosphere that is composed of carbon is now greater (according to google) than the fraction of a percent of the lithosphere that is carbon (both less that one percent of each sphere). Does this mean anything exciting? Could it? I don't know what it is in the hydrosphere or pedosphere. The biosphere, as life is chock full of carbon, has a high percentage of itself that is composed of carbon. Recent Visual Capitalist diagrams of the biomass of life on earth and human stuff surpassing that in mass is getting passed around. Is there some kind a Gaia like hypothesis that the percentage of each spheres composition of carbon should have some kind of equivalence? As we are carbon based life forms and these spheres just different phase states? Could the critical zone just act like a membrane between various states of carbon? Further for something like peak life to occur again (I take that to mean high biodiversity and high biomass) can we ascribe an approximate and appropriate carbon ppm in the atmosphere for such a thing? Can that be determined scientifically by the hypothetical prescriptive equivalence? Or do we just rely on what ppm life evolved from and in. Which is confusing. I know the atmosphere is very small and the lithosphere is very large. I know science isn't prescriptive. Medicine is though. Atmospheric health has been mentioned in papers. I just want a theory and an answer and a diagram of a bar chart of percent over time and flux. That's all. 🙃 I just want someone to tell me that for every plant and animal and microbe to be happy and living their best life the ppm should scientifically be closer to X. Of course we would have to reverse climate change. 350 is just a geopolitical goal, and some say it is a lost one. First time posting so I hope I get a response. Also, I'm new so please be kind.

| Is perception of time, a result of qualia of a sense? Posted: 02 Feb 2022 12:45 PM PST Okay, hear me out. This might sound crazy. Qualia, is the result of data you brain gets from a sensory organ. Like felling , seeing, smelling, tasting and hearing an orange. Quaila is an experience sensory organs give data off, that the brain can understand. It's not math, in the sense of science would put it. So. Why can't perception of time be a sense? Our consciousness, is bound to perception of time. However, is it possible not experience time at all? Well in scenarios like sleeping, comatose, dementia you don't experience time. So our "timesense" is offline. Would that mean, we could hypothetically could alter a part of the brain, that would change perception of time for an individual. Just like splashing water on a person would make them feel wet? Why isn't time perception a result of a sense? [link] [comments] |
