When dogs of different colors breed their descendants can have patches of either color instead of a mixture. Why does that not happen on humans? Posted: 08 Apr 2017 11:45 AM PDT I'm reading a story where people with different hair colors have kids the kids have hair in both colors (black with strands of blond) instead of a mixture of the colors (brown), similar to what happens in dogs and other animals. Why does that not happen to us? What causes it in other mammals? submitted by /u/fassina2 [link] [comments]

What happens in the brain when a deaf (from birth) person reads? Posted: 08 Apr 2017 06:50 PM PDT I was thinking about how when I read silently to myself, I "hear" the words I'm reading in my head. When I read the word "window" I "hear" it, know what it is, and continue on. I don't "see" in my mind's eye a picture of a window unless I need to (e.g. to solve a puzzle I might picture various kinds of windows). Then I wondered, for someone who has never heard the the pronunciation of the word or know what it sounds like, what happens when they read the word "window"? Do they picture it in their mind's eye or does something else entirely different take place? submitted by /u/stymiedcoder [link] [comments]

Are there any phenomena or patterns in the physical world which behave discontinuously (in a mathematical/topological sense)? Posted: 09 Apr 2017 07:09 AM PDT 2nd-ary question: Is there a good reason from physics or philosophy which explains why continuity succeeds so well in describing real-world phenomena? submitted by /u/alkalijane [link] [comments]

Is there any particle that has no antiparticle-or is a particle with no antiparticle a possibility? Also, can anyone tell me what the difference is between a positive and negative electric charge/baryonic number and how it works etc, etc. Posted: 09 Apr 2017 02:42 AM PDT I've heard that Photons are their own antiparticles but other than that is a particle with no antiparticle a possibility or does one exist. Also, what is the difference between positive and negative electric charge and baryonic numbers. What are they. And what causes them? submitted by /u/GrapeKushDreamer [link] [comments]

How is a length contracted planet still in hydrostatic equilibrium? Posted: 09 Apr 2017 01:33 AM PDT From an observer A stationary compared to earth, earths hydrostatic equilibrium is an almost spherical shape. In this shape, the electrical forces that pushes the atoms apart are the same as the gravitational forces that pushes them together (loosely speaking). An observer B moving very fast compared to earth will see earth length contracted, so it could in extreme cases be some kind of disc shape. This point of view should be physically equally valid. So from that point of view, hydrostatic equilibrium of earth will be this disc shape. Electric forces that push atoms apart and gravitational forces that push them together are still balancing each other out, just that this balance now causes earth to be in a very weird shape. So what is different about the earths matter, the electric forces or the gravitational forces, that causes hydrostatic equilibrium to be such a weird shape? I assume that probably every single atom is also length contracted. But how? The charge of the nucleus and the charge of the electron are still the same from B's point of view. So if he solves the schroedingers equation for that system, he would still get approximately spherical Orbitals, not disc-shape Orbitals. submitted by /u/N_las [link] [comments]

What happens when a charged black hole evaporates? Posted: 08 Apr 2017 07:13 PM PDT BG: Black holes emit Hawking radiation, as photons, and the smaller the black hole the more it radiates until it finally disappears. What would happen if you fed a micro black hole electrons to give it a charge, then allowed it to evaporate? Photons can't carry a charge... Would some particles be left behind? submitted by /u/o0shad0o [link] [comments]

[Mathematics] The l_2 norm can be defined in a basis independent fashion, can other l_p norms be defined in this way? Posted: 08 Apr 2017 05:04 PM PDT So I have a question I think I should've known from basic courses, but now I can't seem to find an answer anywhere. Say you have a vector space V, and assume that it is an inner product space (which for any physically meaningful situation I guess one can give V this structure). Then, the l_2 norm can be defined via the inner product without ever referring to a basis. Can one do this for other l_p norms? In particular, can one do this for the l_1 norm? What additional structure (such as the inner product in the l_2 case) does one need to be able to define the l_1 norm in a basis independent way? submitted by /u/fuckwatergivemewine [link] [comments]

How did Humans in the past know that a specific organ does this specific function in the body? Posted: 08 Apr 2017 08:18 AM PDT How were we able to discover that the brain is the organ that controls most of the activities of the body? Without the present technology that we have, How were people in the past able to tell that brain is a most important organ? (Was it because they observed some person got hurt on the head and his whole body and mental health got affected ? ) Because before technology Just not the brain but also other organs..

How do we construct quantum logic gates? Posted: 08 Apr 2017 09:21 AM PDT I can sort of imagine how a NOT gate could be constructed. But a controlled not gate (that does not involve a classical measurement) seems harder. And a phase rotation gate is hard for me to imagine. What process do we have that simply serves to rotate the complex phase of a wavefunction? submitted by /u/EnshaednK [link] [comments]

Does every living thing need to have DNA? Posted: 08 Apr 2017 11:53 AM PDT With the exception of RNA based "organisms" (like viruses, since they're not really considered alive). Does everything need to have DNA to be alive? Basically if we went to Europa and discovered life, would it be possible for the life that evolved on that planet to be DNA-less? Do we have DNA-less living organisms here on earth? submitted by /u/umfrot [link] [comments]

What happened to string theory? Posted: 08 Apr 2017 04:09 PM PDT So back when I took physics in high school, about 10 years ago now string theory (as far as I can remember) was one of the newer theory to try to tie the universe together. Just wondering if it has since been debunked or bolstered in recent years since I haven't really kept up with the field submitted by /u/m1a2c2kali [link] [comments]

Why does metal straighten right before breaking when a direct current is flowing through it? Posted: 08 Apr 2017 03:27 AM PDT Hi folks, Danish highschooler here. For my exam project, we have conducted an experiment where we tried to prove different types of resistances in metals by flowing a current through it. What we did was put current through a wire positioned in the air and measured the amount of current that went through it. I had to take evidence, so I filmed a slow-mo video with my camera and when we put through direct current I noticed that, when we increased the amp, the metal heated up and right before breaking it straightens it self. My first theory was it was the metal becoming so hot that it started to liquidize, but that didn't really make sense because the density of the metal would be higher and wouldn't cause it to snap. I have a video of the experiment here: https://www.instagram.com/p/BSlyYHrl6Em/ Can someone explain to me, why it snaps and why it straightens? Thanks in advance. submitted by /u/Cony777 [link] [comments]

Is "10" in binary pronounced "two" or "ten" ? Posted: 07 Apr 2017 07:35 AM PDT Instinctively i'd be inclined to say "ten", but then I thought about the word two and whether it refers to the notation "2" or the value "two units". Logically it would be two units, I mean counting can exist even without written notations. Therefore "10" in binary representing two units should be pronounced "two". But I'm still uncertain, it raises even more questions like whether A in hex is pronounced "ten" or "ay"... Is there even any definitive answer ? submitted by /u/Cynass [link] [comments]

Why can the sum of two cubes never be prime, but the sum of two squares can? Posted: 07 Apr 2017 07:20 AM PDT 1 is the only number that gives you a prime from what I've found, because 13 + 13 = 2.

Theoretically speaking, could antimatter be contained and stored? Posted: 06 Apr 2017 04:57 PM PDT My understanding of antimatter is limited, but what I do know is that if antimatter meets regular matter then they destroy each other. With that in mind, is it possible in theory for antimatter to be stored? For example, a chunk of antimatter suspended in a vacuum by a magnetic field. I imagine it would take a lot of power and technology we're nowhere close to now, but is it possible? I've seen antimatter used as weapons in a few sci-fi stories so it got me curious about how it would be stored/manufactured. submitted by /u/ParrotSTD [link] [comments]

Does there exist a number system which also introduces a "z" axis? The question "what is the square root of -1?" is a question about a real number that can only be answered by use of complex numbers.

Is it by coincidence that we consider North as "up" on maps and globes? Posted: 06 Apr 2017 06:14 PM PDT Is there an astrological or geological reason that we usually consider North as up on a map?

I think it's interesting that if we drew the maps the other way around, then the Earth's spin and orbits would be in the opposite direction Also, as a follow up, why does it seem that there is more land mass in the Northern hemisphere? Is it coincidence? submitted by /u/Saichotic [link] [comments]
