| Posted: 24 May 2018 09:16 PM PDT Will a new internet port on computers have to be created to handle the climbing internet speeds? [link] [comments]  |
| How can a black hole have angular momentum? What is rotating? Posted: 24 May 2018 11:16 PM PDT I am under the impression that a black hole is a region more than a physical object. Is space itself rotating along with the black hole singularity? Is the singularity rotating? [link] [comments]  |
| Are there more men or women in the world? And how do we know? Posted: 25 May 2018 04:23 AM PDT It seems crazy that there would be a true 50/50 split. Wouldn't it be more like 49.7/50.3 or something? Does it matter? [link] [comments]  |

| How does lava stay hot until it hits the surface? Posted: 24 May 2018 06:13 PM PDT It seems like a cools pretty rapidly once it hits the surface- why doesn't do this when it's 8 feet below ground? Or even a hundred feet below ground? [link] [comments]  |
| Posted: 25 May 2018 04:03 AM PDT From what I know (which might be wrong), nuclear pressure is a force that pushes outwards that keeps stars from collapsing in on themselves. What causes this force? [link] [comments]  |
| How does the Riemann Hypothesis make sense? Posted: 24 May 2018 06:50 PM PDT The Riemann Hypothesis states that all the zeros of the zeta function lie for the real part being half and s being negative even integers. How can this be possible? If we take s = -2, don't we still get a positive sum which is not 0? Similarly, the same thing goes if we take s = -4,-6,... and so on. Does this mean we have some negative terms somewhere? If so, why do we get some negative terms which cancel out the positive terms in the first place? And even if we do, why do we get 0? I don't understand this at all. [link] [comments]  |
| Posted: 25 May 2018 12:40 AM PDT Specifically how was it discovered that most oxygen is 2 atoms of oxygen? Did they use the same process for H2 and N2 as well? [link] [comments]  |

| Understanding the nature of applied Lorentz force, and back-motional emf? Posted: 24 May 2018 04:46 PM PDT When I studied how a current carrying loop, that is designed in a rail configuration, I understood how charges moving in that wire(while constrained within) exposed to an exterior magnetic field that is generated by the loop, it will follow Lorentz law. However, integrated across the whole wire's length, expressed as: F = IL × BIf a component is able to move freely(for the case of the figure-1, the projectile), the length element dL will begin to accelerate, due to the reasons explained above. However, what boggles me is when I imagine the consequence of that motion in relation to Faraday's law. The loop is now changing, the whole system's area is now expanding as the element moves further away, a consequence of that change in flux is stated in Faraday's law: ϵ = −d(ϕ)/ dtSpecifically,ϵ= −B d(A)/dt = −BL d(x)/dtSimplified,ϵ = −vBLAssuming, that this is not a varying magnetic field, the potential difference induced due to motion of the projectile within that length(L) is due to the build-up of charges created from the Lorentz force as well,** are there two forces here? Or is the same force that resulted in motion also separates the charges**? Full system diagram. It confuses me that the initial force that causes the electrons to move(current flow) is due to the battery, and from that motion of charge within the magnetic field created by the loop, the Lorentz force would move rod, at the same time... the Lorentz force would also generated a separation of charges that would create an opposing emf to resist the applied one from the battery.

| How did we evolve from reptiles to mammals? Posted: 25 May 2018 04:27 AM PDT So my understanding of evolution is that over millions of years, random gene mutations lead to a particular species being more and more different to its ancestors to the point where it can be called a different species entirely. I get that when it comes to things like Giraffes evolving longer necks to eat grass or humans evolving finer motor capabilities to create tools and farm and hunt. But how does evolution lead to amphibious, egg-laying reptiles evolving into live-birthing mammals? How could the offspring of, say, a reptile that mutates to give birth via live-birth instead of eggs survive being live-birthed instead of egg-birthed? Or am I thinking about this all wrong? In short, how did we make the transition across classes of animals (fish --> reptiles --> mammals)? [link] [comments]  |
| How do we determine temperature from millions of years ago from sediment? Posted: 24 May 2018 10:17 PM PDT In another post I learned that ice cores only go back hundreds of thousands of years. I asked where we get climate information for millions of years back and was told sediment cores. I'm vaguely aware of how we determine climate from ice core samples, but how do we figure climate from sediment? And how far back do these cores go? [link] [comments]  |
| Posted: 24 May 2018 11:22 PM PDT The lessons I've been taught in school all my life have always started with Pangaea in explaining life. Which is fine, seeing as there is so much information to condense in Earth's entirety. Regardless of life, were there other arrangements of super continents that were equally as prominent or even just notable in Earth's past? [link] [comments]  |
| Why does nuclear fusion release energy? Posted: 24 May 2018 06:05 PM PDT I'm sorry if this is a dumb question, and please correct me if my understanding is wrong. I'm far from knowledgeable in this field and just want to understand this in a semi-basic way. I understand that as more protons are added to the nucleus, the Coulomb force causes them to repel one another more, and the less the nuclear force is able to hold the particles together. What I don't get is why this results in a output of energy. As the repulsion between them increases and the nuclear force weakens, why don't they just cancel each other out, and instead they output energy. If the protons are repelling each other, and the nuclear force is holding them together, shouldn't they just add up to zero? Another thing, why does so much energy get generated? I always see it explained using E=mc2 and that c is so huge is means lots of energy, but I'm not sure I see any mass being converted to energy, so why does it even apply? Any help would be appreciated. [link] [comments]  |

| What caused the geology of Watson Lake, near Prescott Arizona? Posted: 24 May 2018 01:43 PM PDT The strata patterns of Watson Lake are striking, with alternating layers of white and greenish-gray, and still other tones, stretching out seemingly for thousands of feet, if not miles. The pattern of width and color of layers seems very uniform. My understanding is that these rock layers are about 1.7 billion years old and igneous rock (or metamorphic from igneous origin). Could someone with a better understanding of geology answer a few questions, please? What causes the color differences between the layers? How were they laid down so uniformly over such a large area? The rocks are volcanic in nature and uniform in composition, and yet (I'm assuming) were weathered away to produce a set of islands; can you provide some insight into the processes behind that?
