Why did the recent lunar eclipse shadow not pass straight across the moon? Posted: 31 Jan 2018 06:42 AM PST The last sliver of moon disappeared from the top right. The first sliver of moon appeared an hour later from the bottom right. Seems to me it should have been the bottom left. How does that work? submitted by /u/cowsrock1 [link] [comments]

Why does ice on distant asteroids and planets remain solid instead of sublimating into a gas? Posted: 30 Jan 2018 07:06 PM PST The New Horizons probe showed us ice plains on Pluto, and we know that asteroids also contain ice. I understand that these places are very cold, but they still receive some light from the sun. Why hasn't all of the extraterrestrial ice on bodies without atmospheres completely sublimated away? submitted by /u/RedMushtoom [link] [comments]

Understanding the birds in a box question (no weight change), what if the box was moving through the air and the birds were gliding? Posted: 30 Jan 2018 07:55 PM PST If the 'box' was open ended, and the box was either moving through the air or air was being pumped through it at a rate that made the birds glide under no power, would the weight of the box change? I've been talking to people about this for a bit now, and ground effect, closed vs open system are making this tougher to reason than I thought. Any advice is appreciated. submitted by /u/KarockGrok [link] [comments]

Are there any animals that don’t sleep? Posted: 30 Jan 2018 08:45 PM PST I would think some animals with essentially no consciousness don't need sleep (jellyfish, barnacles, etc.). Are there any more self aware animals that never sleep? submitted by /u/TheRaginGoose [link] [comments]

What are the strands of DNA suspended in within your cell nuclei? Posted: 30 Jan 2018 10:54 PM PST In illustrations of DNA strands, they appear to be floating around with space between strands.

Why does adding baking soda to a reduction of water and red cabbage cause the liquid to turn blue? Posted: 30 Jan 2018 08:32 PM PST Hey askscience, I am making some food coloring at home, and the recipe called for boiling red cabbage in water, then separating the liquid and adding baking soda until it reaches the desired blue color. My question is, in terms of the chemistry, why does this happen? What causes the cabbage/water solution to go from a deep reddish-purple to blue? Thanks! submitted by /u/Nickodious [link] [comments]

Is donated blood cleared of hormones? Posted: 30 Jan 2018 05:44 PM PST So when a man gives blood, is there testosterone in his blood that is passed on to the recipient? Same for female hormones. Could someone who needs regular transfusions like a cancer or hemophilia patient end up manifesting second sex characteristics of the other sex based on the hormones in the blood they receive? It would have to be a lot, and very often, though, right? submitted by /u/Blerkler [link] [comments]

in quantum mechanics Is it possible for a piece of matter to disappear and reappear in a different position instantly? Posted: 31 Jan 2018 02:06 AM PST I was having a discussion with a friend the other day about quantum mechanics and he was lead to believe that you can physically observe a piece of matter in the universe, specifically a space ship disappear and reappear somewhere else using the quantum theory. (i'm a novice on this subject) I think I understand that quantum mechanics states that an object can be in multiple places at the same time but when we observe the said object it only appear in one place. So is it possible for an object to be observed disappearing and reappearing in a different place? submitted by /u/DividedQuantum [link] [comments]

Why does helium make voice higher pitched if source frequency remains the same? Posted: 29 Jan 2018 07:15 PM PST I know sound moves faster in helium, but I don't see why frequency should be any different if the source vibration is the same as it is in air. (eg). Say in air, sound speed is R m/s, and there is a vibration at 1 Hz. Vibration starts at t=0. Vibration just started, so distance moved is 0 meters. After 1 second, t= 1, so vibration has moved R(1) = R meters. When t=1, second vibration starts. This distance traveled is 0. Well, because both vibrations move at the same speed, the distance between the first and second vibrations (and 3rd, 4th, etc) is always R meters. And since vibration travels at R m/s, there is a 1 second gap at the receiving end between each vibration. So how does sound speed affect frequency? submitted by /u/yosimba2000 [link] [comments]

Why doesn't aluminium fuse directly to copper? What determines the kinds of metals that can be fused or amalgamated among each other? Posted: 29 Jan 2018 05:53 PM PST Hey there kind scholars! My girlfriend and I have a strange habit of watching old episodes of that Discovery channel show, "How it's made", to relax and sleep. Last night we watched one episode on "Thermal machines" (such as air conditioning units and refrigerators). On a certain moment during the fabrication of the air conditioner, the narrator said that a certain piece of the aluminium "net" component had to be welded to copper using a zinc-aluminium alloy. The question(s) then is (are): Why can't the copper and aluminium be welded directly? What characteristic on a metal determines it to be able to be welded or amalgamated to another? Edit 1: a comma. submitted by /u/lewdlou [link] [comments]

How are raw alpha particles and electrons collected for use in experiments? Posted: 29 Jan 2018 10:26 PM PST In a physics class, our class discussed famous experiments such as Rutherford's Scattering experiment, in which alpha particles were sent into gold foil, deflecting off.

How do we solve problems that don't have constant acceleration? Posted: 29 Jan 2018 10:58 AM PST I understand basic physics and how we solve motion problems using kinematic equations, but these all rely on a constant acceleration. How do we solve problems where this isn't the case, such as a rocket leaving Earth's gravity(since acceleration due to gravity gets smaller the further away you are). submitted by /u/zakerytclarke [link] [comments]

[rocket engineering] Ice as rocket fuel ? Posted: 30 Jan 2018 02:06 AM PST So, my knowledge of rocket science is basically on the level of "avid Kerbal Space Program player". I understand concepts like Delta-V and TWR. So onto my question. As ice defrosts it becomes liquid and then gas. Now water is a bit of a problem here since it actually gets less dense as a solid, but most things it's the other way around. So picture a tank full of some frozen substance, with a nozzle on the end. As it defrosts and evaporates it builds up pressure, expelling some of the gas out the nozzle - and you have a rocket engine. Since space is cold, you may want to use an electric heater to get it going - much like Ion engines are driven by electricity though I know that electric heating is rather more energy hungry. Of course if the substance in question has an evaporation point above the average temperature of space (to the extent that "temperature" makes sense in a near vaccuum) you may not even need that (at least, closer to the sun). Would such a rocket be viable at all ? How would it compare to say - a xenon Ion engine like we already use ? What substances would make the best candidates for an ice fuel in terms of ISP, delta-V for the weight, energy required to melt it and viability of working with the substance ? Frozen CO2 [dry ice] has been proposed as a generator-driver for Martian colonies - would it be a good candidate ? I'm under no illusions that I've stumbled onto a rocket design that the best engineers at NASA and SpaceX have somehow overlooked - I'm just curious about how the idea would work in practise as a hypothetical and what sort of difficulties you could expect ? I see no viability at all for lifting rockets - so think in terms of vaccuum engines to use to accelerate your probe on it's way after you are already in space (much like Ion engines are used). submitted by /u/metalpoetza [link] [comments]

Would a rainbow differ depending on the type of star or atmosphere? Posted: 29 Jan 2018 09:55 AM PST For example could there be a rainbow without Red or Green? Or a Rainbow that is completely blue... etc submitted by /u/MarriedIntoTrashyFam [link] [comments]

What's the current state of research for nuclear power regarding efficiency and nuclear waste production? Posted: 29 Jan 2018 05:21 PM PST (heads up: I'm not very well familiar with advanced chemistry and physics, so I am looking for more of a layman's explanation!) I live in Germany, where nuclear power is commonly not considered clean energy. This is mostly due to the extremly longliving toxic waste it produces. Therefor we have big political movements in Germany pushing for shutting down the nuclear power production all together. Thus (as far as I know) there hasn't been that much modernization going on over the past few decades. A few years ago I read somewhere that nuclear power production today is far below it's potential and that modern scientific research is quite promising regarding the effiency (I think it said that were at ~10% of the potential effiency due to our lack of modernization) and waste production (I remember something about ways to reduce the radioactive waste to minimum of what is currently done). I also remember reading something about ways to recycle spent fuel to bascially use it up until it's gone and power plants that are basically failsafe. Sadly I have no idea where I read this and I don't remember it looking very 'scientific' (iirc it was one of these pseudo-scientific looking inforgraphics). So I was wondering if you could tell me what acutally would be possible if mankind was to decide to heavily invest in modernizing nuclear power production and what could be expected from further research. Are there known ways to get rid of dangerous radioactive waste? Or is this just the propaganda of the nuclear lobby, trying to convince people that renewable energy sources are not the absolutly best option for the future? submitted by /u/uberjack [link] [comments]

How exactly does the immune system ward off external parasites? Posted: 29 Jan 2018 12:57 PM PST My curiosity was piqued by reading about mange in dogs, specifically quotes from this page about how a healthy immune system keeps mites under control: Demodectic mange most often occurs when a dog has an immature immune system, allowing the number of skin mites to increase rapidly. Source: https://vcahospitals.com/know-your-pet/mange-demodectic-in-dogs Since mites are outside of the body and presumably too large for white blood cells or the typical immune system defense against e.g. bacteria anyway, by what mechanism exactly would it be affecting their reproduction? submitted by /u/unthused [link] [comments]

Is Current Audio Amplification Technology at the Limits of Physics? Posted: 29 Jan 2018 02:55 AM PST I'm a full-time busker and have been wondering about the physics behind audio amplification and speakers lately. I currently carry about 15kg (20 if you count the guitar) worth of battery-powered PA equipment around and even with that weight, the amplification reaches to about only 50 people in an open venue. I am wondering if speaker/amplification technology has hit a ceiling when it comes to efficiency and weight relative to dispersion and volume? Should we be looking forward to a future when we can use 5kg worth of amplifying equipment to reach a crowd of hundreds or is that just plain physically impossible? Thanks! submitted by /u/emorcen [link] [comments]

Do birth control pills affect attraction/mate-choice? Posted: 28 Jan 2018 05:52 PM PST I read something that said that birth control pills affect a womens attraction. Specifically that women will choose lower testosterone males who are more genetically similar to them on the pill. If they come off the pill they will become more attracted to higher testosterone and more masculine men. Im wondering about how reliable these studies are?

Posted: 29 Jan 2018 05:20 AM PST I know there's a huge blackhole in the center of the milkyway, but was wondering why the milkyway Galaxy is frequently depicted as having a bright white center. Thanks! submitted by /u/DerpTheKing [link] [comments]

Why are Ramsey Numbers so difficult to find and would finding an efficient algorithm for finding Ramsey Numbers have any benefit for mathematics in general? Posted: 28 Jan 2018 11:19 PM PST I was looking at Ramsey's Theorem (from which the party problem was created) and was surprised to realize that the Ramsey Number for (5,5) is still currently unknown. This problem at first seems deceptively simple. 1) Is an efficient algorithm possible to find Ramsey numbers? 2) Would finding such an algorithm be a "big deal" for mathematics? 3) Would a quantum computer be more useful than a classical one for this type of problem? submitted by /u/Stuck_In_the_Matrix [link] [comments]

In Planet Earth, the Okavango Plains are flooded from rains that happened 5 months ago in the Angoland highlands. How much water fell in order to still be able to create a water-based paradise? How did it not all evaporate/get used by animals, plants, etc? Posted: 28 Jan 2018 06:17 PM PST submitted by /u/queenyeeeezy [link] [comments]

If a flu shot has a certain percentage of effectiveness, does that mean it is more effective against some of the strains than others? Posted: 28 Jan 2018 04:17 PM PST So in the current epidemic, if the flu shot is 40% effective, what is the actual effectiveness against the worst strain? And how does that effectiveness play out? More effective against a smaller exposure to the virus, or having more to do with the health and age of the infected? submitted by /u/texlorax [link] [comments]

Psychedelic drugs are now in the spotlight due to their therapeutic uses. Alcohol is often eschewed for its negative effects.

Does the body actually absorb all of the vitamins in a supplement? Posted: 28 Jan 2018 10:37 PM PST I started taking a multivitamin. The label has more than the daily recommended values for most of the vitamins in it. If we did absorb and purpose the whole amount, wouldn't we have a toxicity risk? submitted by /u/KReese6 [link] [comments]
