| How will we use the power from a fusion reactor? Posted: 01 May 2017 07:43 AM PDT Everyone talks about how fusion reactors will change everything. My question is, how will we USE all of this energy? Will we just use it like we do a fission reactor, using the excess heat to generate steam? If so, it seems kind of a waste of money. Or, is there some way to use the plasma to generate electricity (kind of like the EPS conduits in Star trek). I am only a layman, but I hope to get an answer I can understand. Perhaps they are only concerned with actually getting a working fusion reactor, and then sweating the details later. Thanks! [link] [comments]  |
| How far away could SETI detect Earth? Posted: 01 May 2017 06:17 PM PDT Tried to keep the title short, but basically if you duplicated Earth, how far out could you move it before SETI would not be able to detect our current EM emissions? [link] [comments]  |

| Do animals have an individual scent as well as a "species" scent? Can other animals tell them apart? Posted: 01 May 2017 03:29 PM PDT For example, could my dog (hypothetically) know which individual squirrels have been in our backyard, or just that squirrels in general have been there?

| [Engineering] Why does spacex prefer to land on the ground instead of on a barge at sea? Posted: 01 May 2017 06:03 PM PDT Today Spacex landed a rocket again, and it went back to the landing zone in Florida. But why do they do this instead of landing on a barge? Wouldn't it save on fuel and therefor costs? [link] [comments]  |

| If you have asthma are your lungs always somewhat constricted? Posted: 01 May 2017 04:27 PM PDT Also, does taking asthma medicine such as rescue inhalers make the airways comparable to a normal person's or are they still somewhat constricted? I'm wondering if people with asthma feel its effects even when it's not a full-on asthma attack. [link] [comments]  |

| Do aircraft experience sonic booms as the cross multiples of the speed of sound? Posted: 01 May 2017 06:54 PM PDT Also: Is there a complementary boom when decelerating past sound? What do all of these noises sound like to pilots compared to how they sound on the ground? [link] [comments]  |
| Why does it not matter the way you plug a phone charger in? Posted: 01 May 2017 06:31 PM PDT You can plug a phone charger upside down as well as right side up. I know that with motors, they will spin the opposite direction if the polarities are switched. So why doesn't this happen for the phone? [link] [comments]  |

| What is the distance between pulses of light in a fibre optic cable? Posted: 02 May 2017 03:51 AM PDT In an undersea fibre optic cable, say for example the Hibernia Transatlantic cable, the bandwidth is in excess of 5Tbps. What is the spacing between the pulses of light and how long are the pulses of light in these high bandwidth cables? [link] [comments]  |

| Do the laws of thermodynamics apply to quantum theory? Posted: 02 May 2017 02:56 AM PDT Can't find a straightforward answer on google - any help? :) [link] [comments]  |
| Why does classical science fail at the molecular level? Posted: 02 May 2017 02:44 AM PDT I tried searching for this on the internet but I might not have been using the correct keywords because I didn't find anything satisfying. My question is why can't we use newtonian laws (if I understand the conflict correctly) at the level of atoms. Can the attraction between atoms and their repulsion not be modeled like gravitational attraction? I'm aware of things like the heisenberg uncertainty principle but I struggle to understand why the same problems don't present themselves at the planetary or even our scale. Is it just because of the fact that the molecules are affected exponentially more due to their size? [link] [comments]  |
| Is the Quantum Mechanics concept of superposition falsifiable through any possible experiment? Posted: 01 May 2017 05:55 PM PDT The math of Quantum Mechanics implies superposition in created particles that have not yet been observed. This concept is also used to describe the real-world state of actual particles. But it seems equally possible that real, actual particles have defined characteristics that are simply unknown until observed. (It's not like we can observe the particle prior to observing it.) Is there any possible experimental setup that could falsify superposition? [link] [comments]  |

| What kind of power cord would you need to be able to extract power from a cell phone? Posted: 01 May 2017 09:09 PM PDT I have seen it done where you can have a cord plug into a phone with 100% battery and charge a phone with 0% battery. I am just wondering how this is done and if some phones have software or other things that may prevent this. [link] [comments]  |
