| In the winter when frogs are frozen, are they conscious or asleep? Posted: 16 Jun 2018 08:04 PM PDT Do they see and feel when they're frozen, or do they simply fall asleep? [link] [comments]  |
| Do firefighters have to tackle electric car fires differently? Posted: 17 Jun 2018 06:03 AM PDT Compared to petrol or diesel car fires. I can think of several potential hazards with an electric car fire - electrocution, hazardous chemicals released from the batteries, reactions between battery chemicals and water, lithium battery explosions. On the other hand an all-electric car doesn't have flammable liquid fuel. But do the different hazards actually affect firefighting practice, or do firefighters have a generic approach anyway?

| What metrics make a peninsula a peninsula? Posted: 16 Jun 2018 09:39 AM PDT Why is the Labrador Peninsula a peninsula and Alaska isn't? Is there some threshold ratio of shore to mainland? [link] [comments]  |
| How does the deep sea maintain life? Posted: 17 Jun 2018 02:50 AM PDT Sun light is the main source of power for life but deep in the ocean is pitch black so, how does it sustain life without a high energy source like the sun flowing into the system [link] [comments]  |
| What math function do they use to produce "out of focus" image blurr effect? Posted: 17 Jun 2018 07:12 AM PDT I am doing some hobby calculations about what exactly happens to the light intensity of screen when the image is out of focus. Then it struck me, how do they produce the effect in real life softwares? I'm curious. My results were mostly about finding the area of intersection with some circles. (Assuming aperture is shaped like a circle) Do they use similar methods?? Or do they use just some arbitrary ramp? [link] [comments]  |

| What causes the electric activity in the brain? Posted: 16 Jun 2018 02:11 PM PDT Does it start with chemical reactions? Something to do with ions? What actually causes the signals to occur? [link] [comments]  |
| Do fish know how deep underwater they are? Posted: 16 Jun 2018 12:48 PM PDT Does sea life have a way to sense pressure? Could fish who live close to the surface survive much deeper? How about the opposite? Can they sense how fast they're diving/climbing? [link] [comments]  |
| Posted: 16 Jun 2018 07:20 PM PDT Kind of a layman here, but from what I understand, the heavier something is, the more it displaces time. I've read about a few experiments where a clock in a tower goes somewhat faster than one on the ground. So it makes me wonder, if we colonize something extremely tiny with very little gravity, like an asteroid with 5% of Earth's gravity, won't time travel faster there than on Earth? If we are communicating by, say, lasers, will the difference in frequencies of transmission and reception be important? What about a colony ship traveling sublight speeds to a nearby planet? I guess what I'm asking most succinctly is: in the context of space travel/colonization, what are the practical ramifications of time dilation? [link] [comments]  |

| can there be multiple pairs of electron orbits with the same energy difference? Posted: 16 Jun 2018 09:14 PM PDT is it possible to have 2 sets of orbits (a,b and c,d) or more which have the same energy difference? If yes, if a photon with energy as said energy difference is introduced, which electron would be excited? could we experimentally verify this ? [link] [comments]  |
| Posted: 16 Jun 2018 12:36 PM PDT I was asked this question by a child (11y) and didn't have a fitting answer. Thanks in advance! [link] [comments]  |
| Posted: 16 Jun 2018 01:50 PM PDT Is it the force of external objects that hit it in the early stages of its life? Or it holds the rotation of the first block of materials that formed it? Other question: do we know of a planet that rotates so slowly that an asteroid hit is enough to change its direction of rotation? EDIT: "does a planet exist that rotates so slowly that an asteroid hit is enough to change its direction of rotation?" Is not exactly what I meant. I know that it would be quite improbable due to the mass of the planet but I wanted to know if we have some observational evidence of it. [link] [comments]  |

| Is a combustion engine more or less efficient when in a cold environment? Posted: 16 Jun 2018 09:28 AM PDT In other words, will a cars engine be more fuel efficient when running in a cold or hot environment? [link] [comments]  |
| What is it about vines that allows them to creep? Is it a structural thing? Posted: 16 Jun 2018 03:16 PM PDT I notice that they grow out and at the tip (of grape vines anyway) there are little... fingers almost with hooks at the end that wrap around whatever they encounter. When something close to them is above them, they appear to "reach" for it by curving upward. I'll post a pic. How do they know to go up, and how does their physical makeup allow it?

| Posted: 16 Jun 2018 03:50 PM PDT So I feel like I learned once when I was younger and it should be fairly simple. Most people just say "oh water and wind erosion" or "the land used to be underwater" and ya, I get that. But that doesn't exactly account for why they are SO flat on top and have such sheer drop offs at the ends. [link] [comments]  |

| Posted: 16 Jun 2018 07:13 AM PDT Something I've seen mentioned a few times now and was wondering if anyone could explain in basic terms. Thanks in advance. [link] [comments]  |

| What would happen if one takes a vaccination when they had already been vaccinated previously? Posted: 16 Jun 2018 10:27 AM PDT Theoretically, if one was given the polio vaccination, for example, as a child, then in adulthood they took the vaccination again, would they get sick, or would nothing happen? Is it dependent on the vaccine? I know you can/have to get repeatedly vaccinated for something like the flu, because it changes every other year, but what if it is something like Varicella?
