| How do Photonic-Crystal Fibers work? Posted: 01 Mar 2019 03:10 AM PST I read that photonic-crystal fibers use diffraction to send multiple wavelengths of light down it's core so that multiple information can be transmitted at once. How exactly does diffraction happen with the solid and the hollow cores? Or have I misunderstood something, and it uses total internal reflection? [link] [comments]  |

| Posted: 28 Feb 2019 04:00 PM PST Title sums it up, I'm aware it could also maybe impact how badly you get ill? (A normal cold lasting 2 weeks rather than 1) Just wondering since I want to get mine removed :-) [link] [comments]  |
| Posted: 28 Feb 2019 05:40 PM PST If a Rh- mother has already developed anti-Rh antibodies, it will attack the red blood cells of their Rh+ baby, how come this doesn't apply to the A and B antigens? Regardless of the Rh antigens presence, shouldn't a mother with either an A or B antigen have its antibodies agglutinate with its respective antigen in the mother's AB baby? [link] [comments]  |
| Posted: 01 Mar 2019 03:45 AM PST If you put spin on a ball and it hits a surface the angle of the rebound changes based on the spin. Does the same apply to waves? [link] [comments]  |
| Can you break or bend the rules of the "Fire Triangle"? Posted: 28 Feb 2019 04:50 PM PST In school, we were taught about the Fire Triangle; the three requirements for fire, those being fuel, heat, and oxygen. Being that this was middle school (I think) I assume this was a dumbed down or simplistic version. What are some ways these rules can be subverted? Is it possible to replace oxygen with another gas, or perhaps start a fire without heat? [link] [comments]  |
| Posted: 28 Feb 2019 01:48 PM PST i.e. I have an xbox controller that is powered by 2 AA batteries. My controller is almost dead, at 20% battery life. If I switch out only one battery for a new one, does that increase the battery life of my xbox controller? Or does it remain at 20%? [link] [comments]  |
| How does alcohol cause memory loss? Posted: 28 Feb 2019 05:42 PM PST How does alcohol cause memory loss? I think I remember reading that it's not the BAC that causes it, per se, but rather, the rapid change in BAC; is that right? [link] [comments]  |

| When a star stops fusion reactions and collapses under its gravity, why does it explode outward? Posted: 28 Feb 2019 12:23 PM PST Also, I know some of the time not all the star explodes outward, its core is left behind and forms a white dwarf or a neutron star, how many solar masses does a star need to be to have all its mass launched into space when it goes supernova?

| How do scientists measure how much a land mass moves every year? Posted: 28 Feb 2019 12:05 PM PST I saw a post on reddit stating that Hawaii moves 7.5cm closer to Alaska annually. How exactly do scientists come to this conclusion? Relative to the size of the Earth, 7.5cm is extremely finite. How can they measure the distance it moved to this degree of accuracy given that the shorelines of most islands/continents are not always the same? What is the baseline for this measurement? What is the percentage of allowable error on something like this? [link] [comments]  |

| How do cells ask for more blood flow? Posted: 28 Feb 2019 10:25 AM PST If a cell or region of cells suddenly has an increased metabolic demand (for instance, if there's damage or increased stress to a certain area of the body), how do the cells stimulate more blood flow to the area?

| How many gluons are there in a proton? Posted: 28 Feb 2019 12:23 PM PST At high energies you get a colour glass condensate - but shouldn't the number of gluons in a proton be Lorentz invariant? [link] [comments]  |
