What happens to gravity when mass is converted into energy? Posted: 08 Nov 2016 01:55 PM PST An objective that has mass also has gravity. If the mass is converted into energy, what happens to this gravity? submitted by /u/DngrDan [link] [comments]

Can nuclear waste from a reactor be used to create energy still? Posted: 08 Nov 2016 03:01 PM PST It still produces heat so can't it be used in a BWR reactor again? submitted by /u/HeyThatsGood [link] [comments]

How does a CANDU reactor work? Posted: 09 Nov 2016 04:13 AM PST So im reading a bit about the subject, and came across the Canada Deuterium-uranium reactor. I wonder why it can use natural occuring uranium as fuel and heavy water moderator? Wouldnt the d2o slow down the neutrons to thermal state, and making the u-238 less likely to fission? submitted by /u/laksir [link] [comments]

How do we make the thick sheets of armor for tanks and warships? Posted: 08 Nov 2016 08:17 AM PST So I was just wondering, the composite armor that we use for tanks and the battleships of old are extremely thick and hard, so how do we shape/mold them? How do we fashion this extremely hard and durable materials into the specific shape of a tank or the hull of a ship and how do we get various different sections of the hull to join together? I'm assuming that welding doesn't work due to just how strong the materials are. submitted by /u/BojackToddman [link] [comments]

The latitude of the northernmost point in Antarctica (63°S) is comparable to substantial settlements in the northern hemisphere such as Anchorage (61°N) or Fairbanks (64°N), but the conditions for habitation appear to be much worse.

I was reading about Oviraptors, and it seems they aren't part of the Dromaeosauridae family. Why are they called raptors then? Posted: 09 Nov 2016 01:48 AM PST Dromaeosauridae is the raptor family. I'm wondering how, if at all, are oviraptors and the raptor family related? submitted by /u/iam_potato [link] [comments]

How does the secondary current of a transformer behave? Posted: 08 Nov 2016 05:34 PM PST Image you have 230V and 10A at the primary circuit and you have 11500V and 0.2A at the secondary circuit. So when I place a 50 Ohm resistor in parallel with the secondary circuit, will the current be 0.2A in that resistor because the secondary circuit can only provide that much or will the current be 11500V / 50 Ohm = 230A. Then what will happen to the secondary Voltage? Or what would happen if i place a 500kOhm resistor in parallel with the secondary circuit, will the current be only 0,023A and will the voltage rise? submitted by /u/partyhattrick [link] [comments]

Do all stars spin? And what is the source of a star's angular momentum? Posted: 08 Nov 2016 06:16 PM PST From what I understand of astronomy, which is admittedly not very much, stars form from clouds of mostly hydrogen and helium which collapse through gravitational attraction until sufficient mass and density for sustained nuclear fusion. Wikipedia says that developing protostars acquire protoplanetary disks as random gas motions originally present in the cloud average out in favor of the direction of the [solar] nebula's net angular momentum. But why do solar nebulae rotate in the first place? Is that just a necessary condition for star formation or is there another mechanism at work? Would it be possible for a start to form without spinning? submitted by /u/Iustinianus_I [link] [comments]

Why on a cellular level do we die (rather than go into stasis)? Posted: 08 Nov 2016 03:52 PM PST When there is an interruption in the supply of O2 or organic fuel molecules to our cells (or an interruption in both, such as when blood flow is interrupted), it's obvious that cellular respiration will have to cease as the process runs on O2 and organic fuel. Thus, whatever ATP a cell already has should be fairly quickly depleted, and cellular activity will cease. But why does this lead to our death? Why doesn't this lack of ATP (and consequent lack of the cell to be able to DO anything) simply lead to some kind of stasis? Rather than irreversible tissue damage and/or death of the organism, why don't we simply see a situation where muscles can't contract, nerves can't fire due to loss of Na/K-ATPase pump, etc...but with the possibility of recover once the supply of O2 and fuel is restored? Most machines seem to work this way...when I unplug my computer from it's power supply, it doesn't cause permanent damage to its circuits! In other words, there must be at least some cellular functions that need to be done without interruption in order to avoid permanent damage to the cells, leading to the death of the organism...What cellular functions are like these? Is it that the proteins or other components start to break down, perhaps without some kind of ATP-powered enzymatic maintenance going on? **FYI, I've posted this in the past on another forum, but I think I'll get better answers here! submitted by /u/bruin06 [link] [comments]

If two power plants feed AC voltage/current into the same electricity grid, how do we make sure they are in the same phase to not cancel out each other? Posted: 08 Nov 2016 01:37 AM PST If two power generators feed a sinusoidal voltage into the grid, but one has a phase difference of 180° to the other, wouldn't the voltages cancel each other out? So after the voltage of the power plant is transformed into the appropriate voltage, how do we make sure the voltages have appropriate phase differences? Or does it not make any difference what phase the feeded voltage of each power plant is? submitted by /u/Boshy911 [link] [comments]

Why does marijuana seem to help patients suffering from seizures? Have there been studies that worked out the specific biochemistry of how cannabinoids interrupt a seizure and/or reduce their frequency? Posted: 07 Nov 2016 10:16 PM PST I know that in many states where medicinal legalization is being talked about, often times powerful dialogue in the pro-legalization camp centers on children suffering from intractable seizures. It seems to me if people who are very anti-drug are somehow especially swayed by the idea that it benefits kids, there must be a lot of good research and evidence backing that up. I just don't know the research, and probably wouldn't totally understand the science if I read it for myself, but I'm incredibly curious. Thanks, wise ones!

Why prime numbers (and only them AFAIK) are giving me this plot? Posted: 07 Nov 2016 06:22 PM PST First of all, sorry if this question is dumb. I have been playing today with prime numbers and I have encountered something extremely intriguing (at least for me). I am a software developer and I have written a simple piece of code in Python just to play and see if I can spot some patterns and just for fun generally. I'm no mathematics expert, but I'm very intrigued of why a simple algorithm like this: primes = prime_gen() screen_w = 1600 screen_h = 800 last = 2 while 1: n = primes.next() x = screen_w/2 + math.cos(last) * screen_w/2 y = screen_h/2 + math.sin(n) * screen_h/2 pixel(screen, RED, (x, y)) last = n is giving me this awesome chart http://imgur.com/vzCqBHt ? I have tried normal integers with multiple expressions, but it seems that only subsequent primes are giving this awesome image. Any mathematicians care to explain to me why is that? Thank you. submitted by /u/karoltomala [link] [comments]

When you gain a lot of weight do your nerves and veins grow to accommodate the expanded surface area of your body? Posted: 07 Nov 2016 08:06 PM PST When you lose weight do your nerves and veins shrink? Also, do thinner people have more skin sensitivity due to nerve endings being more concentrated in a smaller surface area? submitted by /u/candy_grrl [link] [comments]

Is the net gravitational pull of a planet towards the centre of the planet, even though that is counteracted by the gravitational pull of matter on the opposite side of the planet? Posted: 08 Nov 2016 05:32 AM PST This is a very rudimentary question, I've drawn a picture to try and illustrate it. Pic Its only just occurred to me that choosing 1 cubic meter of the earth at some point between the centre of the earth and the surface I should find that is it being pulled towards the core by some mass but towards the surface by the mass above it. So the net force is towards the centre, until you reach the centre, where the net force would be zero. In other words an object on earth is being pulled in literally all directions, it just so happens that the net force is towards the centre of the earth, because there is a great deal more mass on one side than the other. Is that correct? submitted by /u/mojave_mo_problems [link] [comments]

Black holes "slow down" time. Is there an astronomical phenomenon that "speeds up" time for a handful of people? Could we use it to "get ahead" in the galactic race for domination/survival? Posted: 08 Nov 2016 06:17 AM PST The question is serious, although it might sound like it's from a c-movie of sorts. You might need to cut me some slack here. From what I understand (and the movies tell me), time "slows down" considerably close to a black hole. It doesn't slow down noticably for the one being close to the black hole, only for the spectator far away. That's relativity, right? A couple of hours too close "make time fly" for the rest of the universe. Is there an opposite phenomenon, where times starts flying by for a few whereas the rest of the universe "slows down"? Maybe what I'm asking is this: is there such a phenomenen and a way to use it to sort of "cheat" on the speed of advancement and development in relation to the rest of the universe? A chance to "get ahead"? submitted by /u/Frankenstone3D [link] [comments]

Why don't we use the Moon for gravity assists when sending probes into the rest of the solar system? Posted: 07 Nov 2016 04:25 PM PST I know the STEREO observatories used a lunar gravity assist, but I can't find any other examples of missions that use the Moon.

Will eating 100ml of ice cubes hydrate you the same way as drinking 100ml of water? Posted: 07 Nov 2016 04:48 PM PST As the title says.

State space feedback controller design with a reference input? Posted: 07 Nov 2016 06:44 PM PST In classical controls, to control a plant with a reference input the simple structure looks like this. Where the controller multiplies the error. I'm having trouble understanding why in state space feedback systems the gain matrix seems to always multiply the state variables rather than the error term. Like this.

How is diesel particulate filter (DFP) regeneration clean for the environment? Posted: 07 Nov 2016 09:56 PM PST I have been wondering about the regeneration of DPF when driving our diesel cars. So DPFs are supposed to prevent pollutant particles from going into our air, so it does it by trapping it in the filter. However, cars have this mechanism where the filter is regenerated as we drive, so we burn off the "soot" so that the filter doesn't clog up. If the soot is burned off, and goes into the atmosphere, doesn't this mean that the filter is not doing anything? I understand that there are NOx and other things being filtered out, but this is regarding particulate matter... submitted by /u/MugaDWhale [link] [comments]

How come ice cubes don't always float 9% above water? Posted: 07 Nov 2016 07:04 PM PST I understand the basic differences in the density between ice and water, and that's why ice floats 9% above water like icebergs, however my classmate has a bottle of water with ice cubes in it right now, and some ice cubes clearly aren't above the water 9%.

Do we know how or why five-sided symmetrical organisms evolved? Posted: 06 Nov 2016 07:50 AM PST The majority of multi-cellular life here on earth is bilaterally symmetric. However a notable exception is the large class of sea-living invertebrates known as echinoderms (starfish, sea urchins, etc), which typically exhibit radial five-sided symmetry. However reading Wikipedia it states that "[t]he larvae of echinoderms have bilateral symmetry but this is lost during metamorphosis when their bodies are reorganised and develop the characteristic radial symmetry of the echinoderm, typically pentamerism". My understanding of evolutionary biology is low but the above suggests to me that an ancient bilaterally-symmetrical ancestor of modern echinoderms found some benefit to this body layoutt -- but it strikes me as an extremely odd mutation. Is there any knowledge or evidence about how, why, or when this might have occurred? submitted by /u/buried_treasure [link] [comments]

What, specifically, are the most "useful" traits of quantum mechanics? Posted: 06 Nov 2016 01:51 PM PST A common refrain in popular science programs(Michio Kaku, Brian Greene, N.D.

Do nucleons come apart and their quark building blocks come together to form these particles or what? submitted by /u/Einstein100dollars [link] [comments]

How does helium affect instruments? Posted: 06 Nov 2016 10:50 AM PST If instruments were played in a chamber filled completely with helium (or other non-oxygen gas), how would it affect the pitch/timbre of the instrument? Would it affect different instruments (wind/string/percussion) differently? I'm a musician & sound engineer, so I understand specifics of music, instruments, and basics of the physics of sound. submitted by /u/clay_vessel777 [link] [comments]

Does air pressure affect the amplification of sound? and if so how does it affect sound waves? Posted: 06 Nov 2016 02:01 PM PST I wanted to know if for example, a sound was reproduced in a high pressure or low pressure environment would it affect its amplitude? An example would be shouting on top of a mountain, is it perceived louder because of the air space or is it also amplified by the low pressure environment. submitted by /u/7Official [link] [comments]
