Why don't plumbers use aluminium pipes instead of copper? Posted: 03 Nov 2018 11:51 AM PDT It seems weird to me, because aluminum is much cheaper by volume and easier to handle, and is also resistant to corrosion. submitted by /u/RadSeed [link] [comments]

Would a Traumatic Brain Injury after the onset of symptoms accelerate the progression of Alzheimer's Disease? Posted: 03 Nov 2018 01:05 PM PDT I know that AD is strongly correlated with development of amyloid plaques in the brain, and TBI causes large increases in the prevalence of amyloids and their precursors. Thing is, most of the research I've seen focuses on the risk of developing AD at some point in the future. What about when it's already present? If a patient with AD suffered a TBI, would you expect it to affect the progression of the disease? -Is anyone aware of any research to this effect? submitted by /u/Flying_madman [link] [comments]

Invertebrate muscle physiology seems so counter-intuitive. What am I missing? Posted: 03 Nov 2018 08:35 AM PDT I can't seem to find enough information on the muscle physiology and biochemistry of invertebrates. I'd like to know firstly, what contractile proteins their muscle fibers use. Do they use similar proteins to the actin, myosin, troponin and tropomyosin or do they use a completely different system altogether? Secondly, where do their muscle fibers originate and insert? They don't have a skeleton or cartilage or tendons, so how do the muscle fibers find leverage? If the exoskeleton is the answer, then still, how do their muscles gain leverage if both attachment points are to the same structure? Based on this then, thirdly, how is invertebrate muscular strength so much higher as a proportion of body weight when compared to their vertebrate cousins? Why can an ant lift 40 times its own body weight over its head but a lion can't push a 7-tonne lorry? Any links would be fine. submitted by /u/Jaffaraza [link] [comments]

What's This Structural Grid In the Eye Of Africa? (Richat Structure, Mauritania) Posted: 03 Nov 2018 05:14 AM PDT There's a group of nearly perfectly spaced circular depressions typically ranging from 280-320 ft apart, spanning from 21.207151, -11.419889 to 21.212295, -11.432566, and there are over 60 of them altogether. I don't see this occurring anywhere else in the region, and I don't think it's a satellite imagery bug due to several of the sites not lining up with the grid formation or distances, but I'm no Geospatial Analyst. Some people claim that the Richat Structure is what used to be Atlantis before the volcanic activity, but I have my reservations on that notion. Any ideas on what those structures might be? submitted by /u/f__ckyourhappiness [link] [comments]

Is bit-rot (magnetic decay/reversal) in conventional HDDs real? Does data "fade" after a long period of unuse? Posted: 03 Nov 2018 09:57 AM PDT Few years back I was reading something and someone mentioned the theory of "bit rot", that over time, the magnetic domains on a platter would randomly flip. This lead me on a research hunt, which unfortunately didn't really turn up anything solid in terms of fact. There is plenty of scientific basis for the theory, namely superparamagnetism, but nothing definitive on the subject of hard drives. The most in detail discussion I've seen is from this subreddit, this post. Top comment claims that average time for a bit to flip is 10 years. I find this hard to believe, as recently I powered up an old hard drive that, I think, hadn't been powered on for ~10 years. Maybe it had been powered on in this time, or maybe I was extremely lucky? I ran a full surface scan and it was all green. Like I said, I can find lots of information on superparamagnetism, but nothing in the context of hard drives. There's not been any studies done, which makes sense as hard drives are frequently cycled and aren't considered long term in that sense. So I'm wondering if anyone here has any knowledge / experience on the topic. I'm not talking about physical damage to the platters, I'm specifically talking "magnetic decay" or whatever it is/isn't! submitted by /u/JackOfAllDrives [link] [comments]

Certain animals have abilities, how are these abilities transferred to a new generation? Posted: 03 Nov 2018 07:34 AM PDT Example: humans can outrun any (land)animal because they can regain energy whilst running, or a type of jellyfish that can return to a younger stadium not every animal can do that, but why can these animals? Is it coded into their DNA? It has to be for DNA is mostly responsible for different animals being different right? But isn't DNA responsible just for making proteïns?

Posted: 03 Nov 2018 07:10 AM PDT Just like the the title says, apparently things like celery allergies in central Europe and peanut allergies in America are isolated conditions.

What do the "real" versions of other gauge bosons do? Posted: 03 Nov 2018 03:24 AM PDT I have no real education in particle physics, I'm just an interested layman. I've asked this question around in the past but I've never received a direct answer. So, real photons are emitted by charged particles and travel space until they're absorbed by something else, right? I can turn a light bulb on and real photons will travel from the filament into my eye and I can see that. Virtual photons aren't really photons at all. They're just something that comes out of the maths when you're dealing with electrical fields. They're related to charged particles in a similar way to real photons, but they're something different. But when I read about gluons and W and Z bosons, I only every see them discussed in terms of virtual particles. My question is, are there such things as "real" gluons, W bosons and Z bosons? If so, how do they get produced? Can nucleons emit real gluons to lose energy where do they go? Is there such thing as a Z-Boson Bulb, that I can turn on to emit real Z-Bosons? Can these real bosons be used for any practical purpose? Sorry if this is a stupid question, it's just something that's been perplexing me for a while. As a bonus question, what does science say about the differences between real and virtual gravitons? Thanks for your answers. submitted by /u/tastyfurrypig [link] [comments]

If I have never taken antibiotics in my life, does antibiotic resistance not affect me? Posted: 03 Nov 2018 02:30 AM PDT Does antibiotic resistance apply to my body or to the whole world? If I take courses of antibiotics, will the bacteria in my body "remember" it? E.g., is there a limited amount of antibiotic courses I can take in my life as an individual, each time weakening my body? Or is it simply, bacteria in the whole world is becoming resistant to antibiotics, and therefore I shouldn't take it if I don't need to. submitted by /u/nikke1234 [link] [comments]

Can we explicitly see what Atomic and Subatomic particles exactly look like, Such as Atoms, Electrons, Protons, Neutrons, Quarks, etc, And if so, Are there any images of them? Posted: 02 Nov 2018 12:21 PM PDT So, I am just a high schooler with little to no advanced scientific knowledge of topics such as this. However, I am incredibly fascinated with them, and I know we do have advanced telescopes which can actually look at atoms and other particles, But do we have any actual clear images of what they look like? I have seen an image of an atom before (I think?), and I have seen that really cool video of a moving electron riding a light wave, but is there any more than that? Like videos or images of quarks and other particles? (Sorry if this is a really simple question, but I am incredibly fascinated with this and have little to no experience in this subject.

From an EE perspective, is an LED at all similar to an antenna? Posted: 02 Nov 2018 05:15 PM PDT I was just pondering how antennas, whether they be directional, omni-directional, or semi-directional are just like flashlights throwing EM waves at certain frequencies, usually radio or microwave, into space. And then it occurred to me to wonder - isn't an LED doing the same thing, just within the range of frequencies of visible light? So it occurs to me to ask, what similarities are there, if any, in terms of electrical design and mechanism of operation, between a light-emitting diode and a radio or microwave antenna? I don't think this comparison applies to incandescent lights, because I believe they work via black-body radiation, but maybe I'm wrong and they are also comparable? Is the current applied to an antenna simply heating it to the appropriate temperature to create the desired frequency of black-body radiation? Basically I'm just brainstorming as to what are the common threads between all of these physical concepts that function as EM sources. submitted by /u/ZippyDan [link] [comments]

An electron entering a magnetic field perpendicularly will undergo circular motion. This would mean it experiences centripetal acceleration, and this emit radiation. Does this mean its radius is not fixed? Posted: 02 Nov 2018 08:25 AM PDT I encountered a physics textbook deriving an equation to find the radius of curvature for a charged particle entering a perpendicular magnetic field. It equated centripetal force (mv2 / r) with magnetic force (qvB) and rearranged to arrive at r = mv/qB. I thought that an accelerating charge emits EMR, meaning it loses energy, thus it's radius increases. How would this formula hold? EDIT: syntax submitted by /u/Vilegun [link] [comments]

How does the Earth's rotation and orbit of the sun affect gravity (if at all)? Posted: 02 Nov 2018 07:13 AM PDT I've been arguing with some flat earthers recently (because it's how I relax), and one thing they commonly bring up is "how is gravity weak enough for a bird to beat but strong enough to hold everything down as we're spinning around the sun - shouldn't centripetal force pull it away?" ​ I think I've got some ideas, but I am 100% not a scientist, I'm just a musician, and so figured I'd ask the fine people of r/askscience instead. submitted by /u/DemosthenesKey [link] [comments]

[medicine/chemistry] Drug names... how do they work?

And lastly the brand names e.g. prozac. But I want to know 3 things: How is the generic name chosen?

The fundamental unit of electrical energy is the photon, not the electron? - "Misconceptions Spread By Textbooks for Electricity" Posted: 01 Nov 2018 07:15 PM PDT I found this resource "Misconceptions Spread By Textbooks for Electricity". I've read through it all and it says a lot of interesting stuff that I cannot confirm, one of which is the title. I can't ask just one question as they are all related, so I will provide some statements from it, so that you can hopefully tell me if they are legit. How accurate is this resource? How accurate are these statements? It goes against everything I've learned. Electric current is NOT a flow of energy, it is actually a flow of matter. ELECTRIC CHARGES are a physical substance. ELECTRIC ENERGY is a wave that travels via a column of charge. ELECTRIC CURRENT is a flowing motion of the charge already present. "Charge" is the stuff inside wires, but usually nobody tells you that ALL METALS are full of charge. Always. A hunk of metal is like a tank full of water, and the "water" is the movable electric charge inside it. In physics classes we call this "the electron sea" or even "electric fluid." This charge is part of all metals. In copper, the electric fluid is the outer electrons of all the copper atoms. The movable charge-stuff within metals gives them their silvery color. We could even say that charge-stuff is like a silver liquid (at least it is silver when it's in metals.) Amperes Are Not a Flow of Energy. The joules of energy flow ONE WAY, down BOTH wires. The battery created them, and the light bulb consumed them. This was not a circular flow. The energy went from battery to bulb, and none returned. At the same time, the charge-stuff flowed slowly in a circle within the ring. There you have the difference between amperes and watts. The coulombs flow slowly in a circle, while the joules flow rapidly from an "energy source" to an "energy sink". Amperes are slow and circular, while watts are fast and one-way. Amperes are a flow of copper charges, while watts are a flow of energy created by a battery or generator. But WHAT ARE JOULES? That's where the electromagnetism comes in. When joules of energy are flying between the battery and the bulb, they are made of fields. The energy is partly made up of magnetic fields surrounding the wires. It is also made from the electric fields which extend between the two wires. The electrical ENERGY flows in the space around the wires, while the electric CURRENT flows inside the wires. The charge-stuff flows extremely slowly through the wires, slower than centimeters per minute. Amperes are an extremely slow, circular flow. Inside the wires, the "something" moves very, very slowly, almost as slowly as the minute hand on a clock. Electric current is like slowly flowing water inside a hose. Very slow, so perhaps a flow of syrup. Even maple syrup moves too fast, so that's not a good analogy. Electric charges typically flow as slowly as a river of warm putty. And in AC circuits, the moving charges don't move forward at all, instead they sit in one place and vibrate. Energy can only flow rapidly in an electric circuit because metals are already filled with this "putty." If we push on one end of a column of putty, the far end moves almost instantly. Energy flows fast, yet an electric current is a very slow flow. What then is electrical energy? It has another name: electromagnetism. Electrical energy is the same stuff as radio waves and light. It is composed of magnetic fields and electrostatic fields. A joule of radio waves is the same as a joule of electrical energy. How is electric current different than energy flow? Let's take our copper ring again; the one with the battery and the light bulb. The battery injects joules of energy into the ring, and the light bulb takes them out again. Joules of energy flow between the battery and the bulb. They flow at nearly the speed of light, and if we stretch our ring until it's thousands of miles long, the light bulb will still turn off immediately when the battery is removed. Well, not IMMEDIATELY. There will still be some joules moving along the wires, so the bulb will stay on for a tiny fraction of a second, until all the energy arrives. Remove the battery, and the light bulb goes dark ALMOST instantly. submitted by /u/8483 [link] [comments]

what are strings in string theory? Posted: 02 Nov 2018 03:52 AM PDT I was reading this article https://brainspacescience.blogspot.com/2018/11/what-are-strings-in-string-theory.html. where I came to understand that the whole is depending on some kind of vibrating string. I am a computer science student, but I want to ask that is it really true that everything we see is made up of some vibrating string. and also one more thing that I know that there 3 dimension. everything we see is in 3 dimensions, but why string theory talks about 9d or 11d? what are those extra dimension in the string theory? geeks please help me understand. if this is mathematical construct, how they are helping us to understand the universe? submitted by /u/badassbilla [link] [comments]

Could our universe actually have 4 spatial dimensions, but our local area of space just be perfectly lined up on a 4-dimensional plane? Posted: 01 Nov 2018 05:42 PM PDT Perhaps this "lining up" could happen through a similar mechanism to what causes a star system to be pretty much flat, or simply by random chance. Whatever the reason, if I understand the math of such a situation correctly (center of mass of every object is on the same 4-dimensional plane, and the initial velocities of every object are also limited to that plane), then no collision between any objects could lead to getting "knocked out" of that 4-dimensional plane. For example, when you simulate 2d physics for a game, you don't need to consider the third dimension at all - every object in the game is lined up on the same 2d plane, so no collision can lead to an object changing its 3rd coordinate in such a way that it leaves the 2d plane. To observers living in such a space, everything would seem to work as if there are only 2 spatial dimensions. I'm not really sure how the length of objects along this extra dimension affects things, in a game things can have no thickness at all and be perfectly flat, so perhaps in the real world some of the mass of every lined up object would have to be symmetrically spread out on both sides of the plane. At the same time, if other areas weren't lined up like this, objects would seem to appear out of nowhere and disappear into nothingness, but we could also be pulled out of alignment by these objects if gravity worked normally along all 4 dimensions, because it extends indefinitely. Just a funny sci-fi idea that's been bouncing around in my head for a while now, but I'm not sure if something in physics would break if it were true. So the TL;DR of this question is whether anything in physics depends on our universe having no more and no less than 3 spatial dimensions. submitted by /u/Tattek [link] [comments]
