Musics with binaural beats, certain frequencies (eg. "417 Hz healing music") - do they really have effects on hormones release in the brain, or brain activities? Posted: 02 Oct 2018 08:54 AM PDT What is the state of science on music and brain activity?

If defibrillators have a very specific purpose, why do most buildings have one? Posted: 03 Oct 2018 07:39 AM PDT I read it on reddit that defibrilators are NOT used to restart a heart, but to normalize the person's heartbeat. If that's the case why can I find one in many buildings around the city? If paramedics are coming, they're going to have one anyway. submitted by /u/Cromodileadeuxtetes [link] [comments]

What is the force carrier of a magnetic field? Posted: 03 Oct 2018 07:07 AM PDT While watching a video explaining electromagnetism, it was stated that the force carrier is the photon. However, my understanding of photons is that they do not contain a charge and are therefore unaffected by magnetic fields. The video mentioned nothing of moving electrons being a force carrier within a wire. How can photons be the force carrier and yet light is unaffected by magnetic fields? What is the relationship between the nuclei of magnetic elements and the electron, if they are unified under the same force? Any clarification, simple or complex, would be greatly appreciated! submitted by /u/IanP23 [link] [comments]

what could cause a peak at 642nm in an H2 spectrum? Posted: 02 Oct 2018 07:54 PM PDT I have a hydrogen gas spectrum tube in a spectrum tube power supply. I have one end of a small bundle of fiber optic strands pointed at the spectrum tube, and the other jammed into the cuvette holder area of a PASCO spectrometer, which is communicating with an iPad via Bluetooth. The 656 nm line is supposed to be there, but I have no idea why I have a peak at 642 nm. What could produce that? spectrum here submitted by /u/mathologies [link] [comments]

Does adding more heat to a pot of boiling water make it cook things faster? Posted: 02 Oct 2018 04:45 PM PDT I have to win an argument. The idea starts off with somebody boiling a decently large sized pot of water. When small amounts of bubbles start to form and rise is what qualifies as "boiling the water". My question is, if you were to add heat and make it a rapid rolling boil, would that cook food inside of the pot faster than if the boil was less "aggressive"? An example for the food would be noodles that take up most of the space in the pot when added to the water. The person I'm arguing with says that since water boils at 100° in an ideal circumstance, the water will not (or at least nearly negligibly) cook the food faster. I think that adding more heat will make more of the water in total hotter (since I assume most of the water isnt actually at its boiling point), which will make the food hotter, which makes the food cook faster (like cooking the noodles in 6 minutes instead of 8). How does this work? submitted by /u/BoilingWaterBoy [link] [comments]

Do higher altitudes have any effect on audible pitch compared to sea level? Posted: 02 Oct 2018 04:14 PM PDT Follow up question, also what about places with high humidity? As far as music goes, unless you have perfect pitch, most people might not be able to distinguish differences since it seems relative pitch between one note to another is more important than a little deviation from a standard arbitrary root note. I figure if helium is lighter/less dense than standard air which causes pitch to go up, I didn't know if less dense air would have a similar effect and vice versa with denser more humid air if measure with a simple tuner. submitted by /u/DrBucket [link] [comments]

Do electrons truly have a non-zero probability of being anywhere in space? Do atoms have a defined size? Posted: 02 Oct 2018 07:26 PM PDT Models showing the shape of an electron orbital often show the space in which the probability of there being an electron is something like 90-95%. If this were extended not to 99% or 99.999999% but 100%, is there space in which the electron certainly won't be? submitted by /u/Chuuume [link] [comments]

What happens between the inner and outer horizons of a Reissner-Nordström black hole? And how is it connected to wormholes, white holes and/or interuniversal travel? Posted: 02 Oct 2018 07:28 AM PDT So this is the first time I'm posting around in this sub. I don't have a degree that is related to physics, maths or any other natural science in general yet I'm really interested about the abstract topics of physics such as black holes. ​ So could you guys please explain the answer of my question as if I'm retarded? I'm fine with the details, in fact I'd be happier if you went into detail and told me about Reissner-Nordström type black holes and the other types in general but I'd be so glad if you could use a pedagogic language that I could at least intuitively comprehend what the whole deal is about. submitted by /u/onatto11 [link] [comments]

Is there evidence that GR is realized with curved spaced rather than torsion or non-metricity? Posted: 02 Oct 2018 09:02 AM PDT I have heard that there are formulations of GR which use torsion or non-metricity of space and I am interested in how one would distinguish them with measurements and, as a bonus, how to imagine what non-metricity actually is. Would these different formulations potentially solve problems like dark matter or dark energy? submitted by /u/Forty__ [link] [comments]

How do you calculate the average sum of dice rolls when a "drop the lowest roll" mechanic is used? Posted: 01 Oct 2018 03:38 PM PDT In various tabletop role-playing games, game designers will often use a system to set character statistics that is some derivation of "roll an x-sided die y-times, drop the lowest z rolls, and sum up the results." The most common example of this is rolling a 6-sided dice 4 times and dropping the lowest result. Now, calculating the average sum of 3 six-sided dice rolls is simple and intuitive, yielding a result of 10.5, but when adding a 4th and dropping the lowest result, the average comes out to a (seemingly) strange irrational number of ~12.22. There are other derivations of this problem that yield other seemingly random irrational values, and while I can get to the result by writing out all the combinations and summing up the probabilities, is there a way to write this problem out algebraically? submitted by /u/TheAwsmack [link] [comments]

Can you 'russian-doll' pressure vessels, one inside another, in order to reduce the design requirements on each? Posted: 01 Oct 2018 09:12 AM PDT I work with high pressure gas infrastructure (>1000 bar) where we use very strong and very expensive pressure vessels to store the gas at high pressure. ​ A colleague came up with a 'novel' solution to this gas storage problem which in my gut I feel isn't plausible but i'm struggling to make the argument against it. I'm hoping you guys can either help me debunk it, or even prove me wrong. ​ His suggestion is as follows: Lets say you have a pressure vessel containing gas at 300 bar. You put this 300 bar pressure vessel inside a second pressure vessel which contains gas at 200 bar. And you then put THAT pressure vessel inside a third vessel containing gas at 100 bar. You now have a russian doll pressure vessel system. His theory is that each pressure vessel will need only be designed to withstand 100 bar of pressure since the delta between each layer is 100 bar. Supposedly this theory would extend to 1000 bar and beyond. ​ Purely based on theory and ignoring the practicalities of transferring gas in/out of the tanks - is this true/not true and if so, why? ​ submitted by /u/itskinner [link] [comments]

How Hard Can Water Get? Posted: 01 Oct 2018 09:53 AM PDT Everybody knows falling into water from great heights can kill you, but what is it a combination of?

Since there is no light pollution on the surface of the moon or certain comets, how come the sky isn't filled with stars and galaxies? Posted: 01 Oct 2018 01:38 PM PDT I just came across a photo on the front page of the surface of a comet. What stood out to me was how there doesn't appear to be any stars visible in the background of the photo. On Earth, a clear night sky with no pollution would show a ton of stars.

What causes being right/left handed? Posted: 01 Oct 2018 09:01 AM PDT Popular joke says it's amazing how many wonderful things we can do with right hand when left one just sits there and doesn't know how to hold a pencil. There are many things that we can do with left hand but not with right one though. For example if one tried to drive a nail with switched hands, not only left hand will swing uncontrollable but holding the nail with right hand feels odd too. I just tried to play guitar with switched hands and both hands had no idea what to do. Actually left hand started adapting slowly when right one couldn't hold a single string correctly. So what actually makes us "right-handed"? Does it have generic background, neurologic? Or maybe it's the way how we learn things like most children just copy what others do, but some children mirror it and therefore they're left-handed. Would child with conditions to be right-handed become left-handed when surrounded by left-handed people and child with conditions to be left-handed become right-handed in such environment? submitted by /u/KakssPL [link] [comments]

If heavier elements come from stars, where did all of the elements from earth come from? More questions as well. Posted: 02 Oct 2018 12:07 AM PDT Since heavy elements are made in stars, where did the gases come from that formed the planets of the solar system? If our star is 5 billion years old and the universe is 14 billion, how did our solar system get the various amount of elements that is has? Did another star exist exactly where ours is today that died out and left the remnants of the heavier elements? If so, how many times do you think the solar system has "reset", I guess. submitted by /u/Various_Reasons [link] [comments]

Can the equation E=MC^2 be applied to nuclear fission? Posted: 30 Sep 2018 09:32 PM PDT In high school physics I remember having questions asking something like "if x grams of uranium undergoes nuclear fission in a reactor how much energy is released?" and we had to us the equation to solve the question. However, from what I understand, E=MC^2 describes matter turning completely to energy. Also nuclear fission only turns a small percent of the matter into energy.

Why are some salts saltier than other salts? Posted: 30 Sep 2018 10:37 AM PDT So, I saw this post here on Reddit https://www.reddit.com/r/pics/comments/9k5lj5/a_perfect_salt_crystal_i_grew/?ref=share&ref_source=link ​ And a commenter replied with a picture of a halite he got from a mine somewhere. When someone asked him to taste it, he said that it tastes less salty than the common table salt. ​ I, for one, am from the Philippines. I grew up living with only two kinds of salt: Sea salt and Iodized salt. Both of them are really salty. Which was a surprise to me when I first tried a pinch of Pink Himalayan salt. It tastes far less salty compared to the same amount of sea salt and iodized salt that I grew accustomed to. ​ And also, watching cooking shows both on TV and online, I cringe when the cooks apply too much salt on their dish. That much salt using what we have here would render our food too salty. ​ So, it makes me wonder. What makes other salts less salty compared to other salts? Aren't they all crystal formations of Sodium Chloride? If so, then what makes one salt less salty than the other? ​ edit: changed "that" to "than" submitted by /u/EarlZaps [link] [comments]

When the weather report says the temperature is X, but it feels like Y because of the humidity, what is the relative humidity they're assuming for Y? Posted: 30 Sep 2018 05:46 AM PDT For example, if its 75 degrees out and 100% relative humidity, the weather report will say it feels like 80 degrees. But when it comes to how something "feels" to a human, temperature by itself is meaningless, so they must be making an assumption about the relative humidity of the "feels like" temperature.

Do satellites generally have on-board computers, and what are they like? Posted: 30 Sep 2018 05:22 AM PDT Does the average artificial satellite of Earth carry a computer on board? How powerful are they compared to the average person on the ground's smartphone, or laptop? Are there advances in spacefaring computers that make their way into consumer models, or the other way round? I want to know all about computers in space! submitted by /u/erasmustookashit [link] [comments]

Does the concept of Zero/Infinity exists in your Universe? Posted: 30 Sep 2018 02:52 PM PDT Hi r/askscience, While me and some friends where discussing the 0/0 problem, we hit the question if the concept of Zero and Infinity exist on an cosmic scale in our universe. Here are two examples what I am meaning: 1.) Speed/Energy: As we all know the maximum speed possible in this universe is c, the speed of light, is it possible, that something contains more energy than an object moving at the speed of light? Also does zero speed, the true stop of matter and consequential the absence of energy exist? I know it's impossible to reach Absolute Zero, so I guess the answer is no, but does a solid proof exist? 2.) Same question as above but let's look at matter instead of energy. Space starts to behave weird when too much matter is concentrated at one point, but is the singularity truly infinite? And final question, is the vast space complete empty (complete absence of matter) or could there be something we don't know of? tl:dr: Can energy be infinite / is it possible that energy is complete absence? Same question with matter. Thanks for your answers. Edit: on second thought, if you consider e = mc2 the only question is, if one of both can get infinite or zero. Edit2: I only ask for real proof or consence many scientists agree on, I've read the rules of this sub. submitted by /u/Hikatokage [link] [comments]

Is body fat under the dermis in your skin really yellow, or is it only shown that color in models for ease of understanding? Posted: 29 Sep 2018 11:50 PM PDT submitted by /u/Well-Rounded- [link] [comments]
