What makes elementary particles and atoms physically solid? Posted: 10 Sep 2017 04:57 AM PDT To my understanding, elementary particles are mostly disruptions in the various boson fields. I do not understand much but am looking for a very dumbed down explanation thanks. So the various field interactions create what we know as quarks and whatnot which make up protons/neutrons etc... And I'm pretty sure interactions in the Higgs field is what gives particles their mass. But what makes that mass 'volumetrically' solid, so that other matter can't pass through it like electromagnetic waves? (I think they can to a degree) I am thinking, why can't mass just be a disturbance in the fields without anything showing for it? If the answer is just "because", would it be possible for there to be mass in a vacuum without any physical space being occupied? Like a standalone interaction with the Higgs field? Excluding singularities even. Thanks very much. submitted by /u/Pentaller [link] [comments]

Why do we need to boil pasta? Why isn't it enough to soak it in water? Posted: 10 Sep 2017 02:41 AM PDT When I make pasta, I usually microwave it with other ingredients afterwards.

Why is there a trail of red light lagging behind a moving red laser? Posted: 09 Sep 2017 09:35 AM PDT Hey!

What is an "interaction-free quantum measurement"? Posted: 10 Sep 2017 07:37 AM PDT This nature paper from 2 years ago and another one from the 90s with Anton Zeilinger have proven that you can have an "interaction free measurement". I thought all a measurement was is a particle interfering or "touching" its environment, and has nothing to do with an observer (or god forbid consciousness).Usually when people bring up quantum woo people say that a measurement is just an interaction. So what does it mean when you can make a measurement without having an interaction? They said something about the quantum Zeno effect in the linked paper and I know that's where you keep interacting/measuring a particle so it never changes, but what are the implications of "interaction free measurement" since I thought all measurement was just interaction with the environment/decoherence? submitted by /u/someinternetdudejoe [link] [comments]

How does a butterfly get a new exoskeleton inside of the chrysalis? Posted: 09 Sep 2017 06:44 PM PDT So a caterpillar will molt for the final time and under its old skin will be a chrysalis. Inside the chrysalis a butterfly forms by breaking down a bunch of the old caterpillar bits and using that material to grow its "imaginal discs" into new legs and wings... but how does it get a new exoskeleton around its organs? When a little caterpillar molts it's just skin off the main skin layer, like if my skin flakes off there's a layer pumping out more skin underneath. But when a caterpillar pupates the entire outer skin layer becomes a shell. Is there a second skin around the organs that becomes the butterfly's skin? Does the new skin grow from "imaginal discs"? Does the inner skin layer somehow get relocated closer to the organs? submitted by /u/butterguy34 [link] [comments]

How were forest fires contained 150 years ago, especially in remote areas like the west?

If quantum entanglement can't be used to transmit information, then how is this experiment (see description for link) possible? Posted: 08 Sep 2017 04:41 PM PDT Been catching up on some reading, came across this experiment here. I've been told over and over again that entanglement can't be used to transmit information.

Can someone please explain the science behind a snowball hitting a wall? Posted: 09 Sep 2017 05:24 AM PDT I watched a video a while ago explaining how when a snowball reaches a certain speed it will explode on impact no matter what angle you throw it at. That's why you end up with a perfect circle of snow left on a wall when the snowball hits it. But this is true for any substance I think. If you get something to a specific speed it will explode on impact. The video I watched related this to the rods from god project. I was trying to explain this to a friend and I couldn't remember the phenomenon or the science behind why this happens and I couldn't find the video I watched so if someone can help me out by explaining this that would be great. submitted by /u/MerlynStar [link] [comments]

How are scattering cross-sections measured? Posted: 08 Sep 2017 08:19 PM PDT The question itself is: I have seen on certain textbooks/study material that in order to measure the amount of particles scattered by an angle a, one must place a detector in such an angle with respect to the direction of the incident particles and pointing towards the target and simply count events. However, I can't see how it does not happen that the particles reaching the detector come from various impact parameters. To try and make it a little clear: If you put a detector far away and with a big scattering angle and count the amount of particles reaching it, you will get some counts belonging to particles with big impact parameter which were not scattered at all. On the other side, if you place the detector with no angle at all, you won't measure the amount of particles which were not deflected, because those (usually, I guess) have a big impact parameter. Maybe I have a wrong understanding of what a scattering cross section is. From what I understand, in the case of a rigid potential such as a hard sphere, it is the area of interaction of the potential projected onto the plane of incidence. With continuous potentials, this generalizes to a measure of how strong/how much the incident beam is deflected by the target. submitted by /u/Paul-Lubanski [link] [comments]

Maximum information density of photons? Posted: 08 Sep 2017 07:59 PM PDT It impossible to transmit information faster than the speed of light (instantly), but is there a limit to the amount of information that can be transferred at the speed of light. submitted by /u/Quantum_P [link] [comments]

Why does the intensity of all electromagnetic waves dissipate at the same rate, 1/r^2?

Anyone have a more simple explanation as to why all electromagnetic waves behave this way? Thanks. submitted by /u/agentbobR [link] [comments]

Why Dimensional Analysis / Buckingham Pi Theorem Works? Posted: 08 Sep 2017 04:58 PM PDT I know that we can use dimensional analysis to experimentally correlate several variables and to reduce the amount of experiment that you need to do to determine those correlation. I also know that it can be used to scale things up. Example: http://www-mdp.eng.cam.ac.uk/web/library/enginfo/aerothermal_dvd_only/aero/fprops/dimension/node6.html In the example above, we want to study how drag (F) is effected by fluid velocity (v), viscosity (mu), density (rho) and diameter (D). Using dimensional analysis / Buckingham Pi Theorem, we can reduce the variables into Drag Coefficient and Reynold numbers. But why is this valid? Why does Buckingham Pi Theorem led to a conclusion that increasing fluid velocity and increasing fluid density will have the same effect on the drag coefficient because both conditions led to the same Reynolds Number? Buckingham Pi Theorem did not take into account any fundamental principles. Every readings I encountered only explained why dimensional analysis is necessary and how to do it. I never found any resources that tried to explain why Buckingham Pi Theorem is justified. submitted by /u/dkurniawan [link] [comments]

What is the speed of kinetic energy? Posted: 08 Sep 2017 03:23 PM PDT This might be an odd question but is there a speed of kinetic and potential energy? I ask this because I'm sitting on a couch right now and there is a water bottle about a foot away from me. My movements and even my heartbeat is making the water in the bottle move. If I get up, the water is still. So I know it's me and not, say, air current from my fan or AC. Now, I've been trying to figure out how fast it takes my heartbeat to transfer into the water. Is there a set limit or is it based on the force, in this example my heart, acting on the water? Or is it like sound or light where it only moves in one single speed? submitted by /u/Onyx_Initiative [link] [comments]

[Physics] What is the difference between the sounds of different vowels? Posted: 08 Sep 2017 08:22 AM PDT I'm not asking about how they're made or the physiology in any way. I mean, if you recorded two sustained vowel sounds, chopped off the beginnings and the ends, and compared the sustained sounds in the middle, what differentiates them? What differentiates a Long A from a Short A or an E? Is it pitch? Timbre? submitted by /u/ArMcK [link] [comments]

Why is CMB in every direction? Posted: 08 Sep 2017 01:47 PM PDT The cosmic microwave background radiation (CMB) is observable in every direction. It is the radiation emitted by the opaque plasma that existed after the big bang that is now reaching us 13 billion years later. if we are still moving away from the origin of the big bang, surely after 13 billion years we would have exited the bounds of the plasma cloud that sources the CMB.

At what speeds to hydrogen atoms become deadly? Posted: 07 Sep 2017 10:46 PM PDT I recently read this article about how traveling at light speed in science fiction would kill human travelers as the hydrogen atoms, when struck at these speeds, would give off an extremely fatal dose of radiation. Pardon my ignorance here, but at what speeds does this occur? Say the hypothetical vehicle is moving at 75% light speed instead of 99% - is the dose of radiation less? Is it an all or nothing sort of thing or would it be the sort of thing that ramps up over time? Say our hypothetical space ship is slowly gaining speed to approach 99% lightspeed. At what point do they start getting bombarded with this fatal radiation? Would it be like hitting a sudden radioactive brick wall or would it be more akin to a slow creep? How do they work out exactly when these reactions occur in these hydrogen atoms? Thanks for your time! submitted by /u/Krytenton [link] [comments]

Does it happen? If that is possible, did Houston really sink 2 cm (or any other measurable value that we figured out) Would such a sinking possibly cause an earthquake?

How do distant neurons know to connect with each other to create new pathways? Posted: 07 Sep 2017 06:59 AM PDT To be clear I'm talking about distant unconnected neurons, not just a change in dendrite strength or spine quantity. Reading through various wikipedia articles, I understand that a neurons axiom sends out growth cones and that these cones are guided to a new neuron via chemical signalling. But how does a neuron know to send out a growth cone, and how does the receiving neuron know to send out chemical signals to guide it? Is it a case of luck? Something like: a neuron is receiving unusual stimulation due to a novel circumstance so it puts out signals to say come hither. Meanwhile another neuron is not generating the response it wants and sends out the growth cones. Thus if you are learning to kick a ball at the same time as speak mandarin you might find in future that you speak Mandarin better when kicking a ball because the connections got a bit mixed up. If this is the case then what defines the difference between the neuron that sends the cone and the receiver? How does a neuron know that it is not generating the response that it needs and so sends out the cone or chemical signals? submitted by /u/SystemicPlural [link] [comments]

If the sun emits white light and is extremely hot, why does light bulbs that emits white light not fry us? Posted: 08 Sep 2017 03:48 AM PDT Why does it not fry me when I am just a few meters away like I would with the Sun? Am I missing something in the equation that affects how much heat is produced? submitted by /u/AoiMizune [link] [comments]

How are islands like the ABC islands formed? Posted: 07 Sep 2017 01:52 PM PDT There are no volcano's anywhere around them so... How did they get there? Here is a picture submitted by /u/frendion [link] [comments]

Is it possible for the frequency/severity of earthquakes to be affected by climate change? Posted: 08 Sep 2017 01:26 AM PDT I mean, I understand the basics - earthquakes are shifting tectonic plates rubbing against each other and that. I'm wondering if there's any connection at all to climate change though - for example, IF they're affected by volcanic activity and IF that is somehow affected by climate change, there could potentially be a link? submitted by /u/Eggerslolol [link] [comments]

How do we know what comprises the insides of the Sun? Posted: 07 Sep 2017 08:29 PM PDT so was watching this recent Kurzgesagt vid https://www.youtube.com/watch?v=J0ldO87Pprc ... which got me thinking, how can we possibly know how the Sun is layered? obviously no human has gone to the Sun, much less bored thru to the center. no machine is capable of doing that either for obvious reasons. so what sort of a super xray telescope (if theres such a thing) do they use to see what's inside of any given star or planet or any other object moving thru space? are these are best guesses/estimates based on what we know of our own planet? are these guesses based on several stages dead stars/white dwarfs? I'd be very interested to know if someone could ELI5. submitted by /u/redditor787 [link] [comments]

Do any of the photons emitted from the Sun that reach Earth come directly from fusion reactions, or are all of them emitted by the outer plasma as thermal radiation? Posted: 07 Sep 2017 08:25 AM PDT So, being that nuclear fusion only happens at the Sun's core, do the photons emitted from those reactions ever escape the sun, or do they all crash into something on the way out, and any light we get is from regular thermal radiation in the sun's outer plasma? submitted by /u/Vidyabro [link] [comments]
