How to break strong ethanol & oil emulsions? Posted: 10 Nov 2021 05:34 AM PST Hello, I have been struggling to break essential oil-alcohol emulsions. I tried many experiments but nothing came out of them Fraction distillations, adding water or salt or both, supersaturated solutions, non polar solvents, heating, cooling but all I'd get would be a turbidity or emulsion or louche that doesn't break. Some concrete examples are the following: Pastis, raki, ouzo effect, absinthe. If you dilute the following liquors with water they form an emulsion in the form a white turbid solution (ouzo effect) Any idea? Thank you for your time! P. S: I had some ideas in mind like centrifuging, but I am not planning to pay a few 100 bucks to make a couple of experiments.. submitted by /u/Unlikely_Lake_8433 [link] [comments]

Why are there atmospheric tides at 12 hours? Posted: 09 Nov 2021 10:37 AM PST I've read around this a little and got answered such as 'it forms a square wave rich in harmonics...' to ' resonance theory and free oscillation in the atmosphere', but as far as I can understand, it's due to the rate of heating and cooling being uneven. Can someone help with a simple ish answer? Thanks in advance! Edit: the title should say with a frequency of 12 hours. submitted by /u/Semi_dad [link] [comments]

[Semiconductors] How does the diffusion of dopants create features? Posted: 09 Nov 2021 04:22 PM PST Say I have an integrated circuit with 100 NPN transistors on it. How are such features actually created? Like, I'm imagining an NPN transistor as an area of the chip where you've got a bit of phosphorus at the collector/emitter and some boron at the base. But, how do you get these dopants where they're supposed to go? submitted by /u/MeleeMeistro [link] [comments]

If canned air gets cold because the energy needed to change the liquid to gas is pulled from the metal can, would it work in a refrigerator? Posted: 09 Nov 2021 12:46 PM PST Or if the can was already cold? Because then there wouldn't be any heat to draw from the can to convert the liquid to gas. submitted by /u/SinJinQLB [link] [comments]

Why can't the immune system create antibodies that target the rabies virus? Posted: 09 Nov 2021 12:08 AM PST Rabies lyssavirus is practically 100% fatal. What is it about the virus that causes it to have such a drastic effect on the body, yet not be targeted by the immune system? Is it possible for other viruses to have this feature? submitted by /u/jla- [link] [comments]

How is it possible that each star in the sky puts out enough photons that I can see it from any slight deviation in my position on earth? Posted: 09 Nov 2021 01:28 AM PST If I'm looking at a star in the sky, billions of miles away, and I take one step to the left, I am stepping into a new stream of photons from that star. What is the resolution of this line of sight? Is there theoretically a small enough distance that I could move to fit in between the stream of photons? submitted by /u/reverendrambo [link] [comments]

AskScience AMA Series: Greetings, Science fans. I'm a paleontologist, science editor and author, Henry Gee. AMA about evolution, extinction, apocalyptic disaster and my latest book 'A (Very) Short History of Life on Earth' Posted: 09 Nov 2021 04:00 AM PST I'm an author and editor on the science journal Nature, the place where scientists like to publish their coolest finds. As Nature's resident fossil hound for more than 33 and a third revolutions (which must be a long playing record) I've had the honor and privilege of steering the first feathered dinosaurs, the fishapod Tiktaalik and the hobbit Homo floresiensis into the light. I know more secrets than the average spy. In my new book I've poured it all on to the page and discovered a lot about evolution, extinction and climate change, both now and in the past. You can find out everything you need to know about my book here: http://www.averyshorthistoryoflifeonearth.com. I'll be here at 1pm ET (18 UT), AMA!

Between Eusthenopteron and Panderichthys what happened to the anal fin? Posted: 08 Nov 2021 05:53 PM PST Looking at the charts of evolution of land animals the anal fin disappears between Eusthenopteron and Panderichthys. Do they become part of the pelvis?

Given a planet with higher gravity than earth, lets say 3g, do humans become more or less bouyant in regular water and why? Posted: 08 Nov 2021 08:25 AM PST Considering we can easily float on water in our current planet, if the gravity would increase we would be heavier but so would the water, would this extra weight make the water easier to swim in? submitted by /u/GrandTusam [link] [comments]

How does a scintillating scotoma create perfectly straight zigzags that retain their exact same geometry throughout the growing event? Posted: 09 Nov 2021 05:38 AM PST As I understand it, the event is the result of a cascade in the visual cortex, but what I don't understand is how the form of the visual representation can remain completely fixed throughout the approximately half hour of growing from a pinpoint to expanding beyond periphery. I experience them relatively infrequently, but fairly regularly, and I always want to know more about them. As a secondary question, how would I go about finding if there is a study on this to volunteer for? submitted by /u/Paracortex [link] [comments]

Do we or can we ever know how our immune system evolved? Posted: 08 Nov 2021 06:24 PM PST I've been reading Immune by Philipp Dettmer and I'm simply blown away by the complexity and ingenuity of our immune system. So, my question for you is do we know or will we ever come to understand how our immune system evolved to get to this point? It's simply perplexing how complex the system is. submitted by /u/membershipreward [link] [comments]

Can the energy output of a fusion reactor be throttled? Posted: 08 Nov 2021 09:23 PM PST Scroll to the bottom for the more direct question. For context - I'm writing a science fiction book where I'm mostly trying to keep to physics, with a few "hand wave" or "inventions" to make the setting I pictured. One of these things is small fusion reactors that power spaceships. Specifically Boron-11 fueled reactors (loosely based on these two: HB11 and Tokamak ST40). As I understand, getting electricity from the heat generated by the reactor requires a steam turbine engine, or inefficient thermocouples, or some combination of both. My question is, is it possible to "throttle" the reactor once the actual fusion reaction has started? Can you somehow change the rate at which it would 'burn' through the Boron-11 fuel to modulate the energy output? Or is it more of a "once it's on, it's on and this is exactly how much energy it will produce until it's off" type of thing? Thanks so much! submitted by /u/MoviesColin [link] [comments]

Why does the JWST need to be in a "halo orbit" at the L2 Lagrange point? Posted: 08 Nov 2021 09:53 AM PST I thought the point of putting satellites at the Lagrange points was that the unique gravitational properties of these spots in 3-body systems allowed them to basically sit still with little to no fuel needed to keep them there in a stable manner. Reading about the JWST I saw that the telescope will be in a constantly moving Halo Orbit, which requires fuel to maintain stability. Why would that be necessary? submitted by /u/Ephemeris [link] [comments]

How do scientists decide whether create a new phylum or class or others depending on a classification variables? Posted: 08 Nov 2021 06:33 PM PST So I am a biology major and I am fascinated by phylogenetic studies and systematics. Yet I don't understand how they decide to make phyla, class (some even make sub phyla, division, etc.) it is as if they cannot agree on a particular criteria.

Can someone tell me the total number of subclades or provide a link to a list of subclades? submitted by /u/ikarosswings0 [link] [comments]

AskScience AMA Series: I'm Mike Parker Pearson, Archaeologist and Professor of British Later Prehistory at University College London, here to talk about my research around the world and on Stonehenge, AMA! Posted: 08 Nov 2021 04:01 AM PST Hi, Reddit! I've worked on archaeological sites around the world in Denmark, Germany, Greece, Syria, the United States, Madagascar, Easter Island (Rapanui) and the Outer Hebrides. I have been UK Archaeologist of the Year and am a Fellow of the British Academy. My research on Stonehenge over nearly 20 years has helped to transform our understanding of this enigmatic stone circle, including the discovery of a new henge, a settlement where Stonehenge's builders may have lived, and the quarries for Stonehenge's bluestones in the Preseli hills of west Wales. I've published 24 books on a wide variety of archaeological topics, but I really love being out doing fieldwork. You can follow more of my recent work on PBS' Secrets of the Dead episode, where my team and I painstakingly searched for the evidence that would fill in a 400-year gap in our knowledge of the site's bluestones. The episode reveals the original stones of Europe's most iconic Neolithic monument had a previous life before they were moved almost 155 miles from Wales to Salisbury Plain. I'll be ready to go at 3:00pm EST (20:00/8:00pm GMT), AMA! Username: /u/ArchaeologyUK2021 submitted by /u/AskScienceModerator [link] [comments]

Is there higher background radiation directly under the Aurora? Posted: 07 Nov 2021 11:03 PM PST If i'm not mistaken, earth's magnetic field deflect charged particles, and pushes them to the poles, creating the Auroras. Also if i'm not wrong, the background radiation can vary really highly from place to place, because it's affected by many variants. But is there any increase in the background radiation, if you stand right under the northern lights or the cosmic radiation level stay consistent? submitted by /u/Rider_Raccoon [link] [comments]

In a phased array, what are the factors limiting coherent and non coherent integration? Posted: 07 Nov 2021 06:59 PM PST I've read that when integrating radar pulses, the SNR gain when performing coherent integration is equal to the number of pulses integrated. In non-coherent integration (regardless of technique used), the snr gain is equal to only the square root of the number of pulses. I am curious why you'd ever use non coherent integration when coherent integration's gain is so much better. submitted by /u/commercial_skin2107 [link] [comments]

Is the "packed sphere" graphic used to represent an atomic nucleus accurate? Posted: 07 Nov 2021 09:08 PM PST I know of course that the electron visualization of a "moon orbiting a planet" is totally incorrect, electrons are best visualized as clouds of probability. There are a ton of beautiful visualizations for these on various websites, including Falstad. There doesn't seem to be any information about atomic nuclei though. Are they best visualized as the classic "packed sphere"? Or should they be represented as a probability cloud also, and if so, what does that look like? Or do we simply not know? submitted by /u/makhno [link] [comments]

How does a computer know it needs to use a float/how does it derive the mantissa? Posted: 07 Nov 2021 02:29 AM PST So, I've been educating myself about floating point numbers and I understand how a float is represented in binary. I understand that it uses a sign, a mantissa as the body of the number, and an exponent as the offset for the floating point. What I'm not putting together in my brain is: How can it perform mathematical operations on, say, two integers, and then come out with a float? Let's say we're dividing 1/3. I know how 1/3 as the decimal value .3333... would be represented as a floating point number, and I know how to make that conversion, but a computer doesn't know what .3333... is. Somewhere, it has to realize both "I can't perform this operation" and "the sign, mantissa and exponent to represent this floating point number are...". The resources I've found explaining how those things are derived is only ever deriving them FROM DECIMAL NUMBERS, which obviously, the computer can't actually understand or do anything with. How does this calculation, (1/3), happen programmatically? What are the "in between points" between telling a computer "divide 0b0001 by 0b0011" and ending up at the correct floating point number? submitted by /u/LordWorm [link] [comments]

Why hasn’t bacteriophage therapy become commonplace yet? Posted: 06 Nov 2021 08:26 AM PDT I feel like it's a discovery on par with something as revolutionary as solar power, but I rarely hear about it ever on the news.

Does the human body secrete more, less or equal amounts of sweat in dry versus humid environments? Posted: 07 Nov 2021 04:03 AM PST hot, humid environments hinder evaporation, causing a person to be visibly more sweaty than they would if they were in a dry climate. However, my question is this this. If you were to place the same person in both environments with equal temperature, one with zero humidity and one with 100% humidity would the total volume of secreted sweat be more, less or equal in one environment over the other? What if we conducted the same test again, but this time rather than equal temperatures, we used the "feels like" temperature index. In the dry environment it would measure 107 degrees, and the humid environment 95 degrees with a relative humidity of 50%, resulting in a feels like temperature of 107 degrees. Which environment would a person produce more sweat in if there is a difference. This question originated from a discussion with friends about that new movie "dune". We are debating if a hot humid environment is more or less dangerous over a hot dry environment 🤔. submitted by /u/MTA427 [link] [comments]

How small and detailed could we make a Fresnel lens? Posted: 06 Nov 2021 08:38 PM PDT Seeing them in the wild, you either look at it from a distance or they're quite grainy, I know they're cheap. So, probably the image might look slightly like the way insect-vision is portrayed in movies, segmented like, but if we can make the tiny tiny little mirrors and sensors in DLP projectors and smartphone camera sensors, (I don't know if the features are smaller on phone cams or pro 16k cams or what) is there any way, expensive and convoluted it may be, to manufacture a super small scale fresnel lens that would provide a clear picture. I understand this would likely never be profitable in a smartphone or anything but I just love the idea of a telescope that's much wider than it is long, or a pair of binoculars that's scarcely thicker than some thick glasses. In case you can't tell I don't know how optics work.. I flaired it for Engineers because I suppose that's closest? Rather than physics? I also just imagined a microtelescope could be made using a DLP mirror module as the collecting mirror with a little sensor in front of it, the uses however, escape me, aside from proof of concept or just messing about. submitted by /u/StrangerThanDicktion [link] [comments]

If we divide numbers in A004090 with A060384 (sequences in OEIS related to Fibonacci numbers), will we get a constant value? Posted: 06 Nov 2021 06:23 AM PDT This is related to the Fibonacci sequence. In OEIS, there are many sequences related to the Fibonacci sequence, like the sum of digits of Fibonacci numbers A004090 and the numbers of decimal digits in n-th Fibonacci number A060384 I made graphs that showed the results of dividing A004090 with A060384, and when I drew the formula, it seemed like the graph tended to get close to certain value. The graphs For n = 500, the graph got close to 4.182, and for n = 10000, close to 4.48.

Is it possible that new life has spawned on earth but we just didn't notice?

Is it possible other life has spontaneously been created but it didn't reproduce so it just died off before we noticed it? submitted by /u/icey561 [link] [comments]

How are granules made from powders to make those instant drink packets? Posted: 05 Nov 2021 01:03 PM PDT Crystal Light, Kool Aid, hot cocoa, whatever. Consumer product drink powders are granulized, don't clump in mild humidity, and dissolve quickly/easily as compared to fine powders. How do I take my DIY drink powder mixes and "granulize" them? submitted by /u/ostreatus [link] [comments]
