| Do bacteria change the nutritional content of milk when they turn it into yogurt? Posted: We make our own homemade yogurt, by heating milk in a slow cooker, then cooling it and adding a starter culture to sit overnight. This has led me to wonder whether the nutritional content of the resulting yogurt actually differs from the milk we put in. Could the yogurt have more or fewer calories than the original milk? If so, where did the extra calories come from, or where did they go? Is it possible that the yogurt has more protein, or different vitamins? What would be used up from the milk in order to produce these? [link] [comments]  |

| Posted: I apologize beforehand if this question is confusing, I'm having difficulty figuring our how to word this exactly. I've heard this phrase said a number of times before, but I'm not entirely sure what exactly this implies. For instance, the ratio between strong and weak nuclear forces is included in this statement. Are there some conditions in which the ratio would have changed? Essentially, I'm curious about the mechanics of "determining the fundamental forces". Can anyone give a better explanation for this? [link] [comments]  |
| Posted: Sorry if this is a dumb or basic question. I'm not very smart so I just want to be able to wrap my head around this. Blame Mythbusters for lifting a car with a household vacuum if you must. It all made me think of dark energy and how the vacuum of space actually works. Would a complete vacuum in one region of space exert any influence over a non-complete vacuum right next to it? Would there be pressure differences that would equal out over time as one pulled matter towards it from the other? Do the variable parts of the vacuum of space have any interrelationship at all or is it all just passive without an energy source powering one part or another as there would be with a home vacuum cleaner creating the vacuum?

| Posted: Do the other quantum numbers come into play to allow non-S orbitals to hold three or more? I'm definitely missing something here, it seems like what I've read about the PEP doesn't line up with, well, the entire periodic table. [link] [comments]  |
| Can the hardness of rubber change after being under cyclic loading (compression and tension)? Posted: I know that hardness is typically considered a material property but I also know enough stress will create changes in the molecular properties of rubber. In the long run I'm trying to relate an easily measurable property of rubber to its lifespan under cyclic loading. Any fingers to point me in the right direction would be great however a simple answer to the titled question would be greatly appreciated. [link] [comments]  |
| What's happening inside a propane cylinder when it's being filled? Posted: I understand that propane in a cylinder is kept in a liquid state at ambient temperature when the pressure in the vapor space reaches a certain level. I'm just curious what's happening to the gas and liquid inside a tank that is being filled with liquid propane. Are the pumps typically used strong enough to force liquid into the vessel and cause the vapor being compressed to condense, or is some other physical process happening? Thank you.

| Why do flashing lights cause seizures? Posted: I've never understood how epileptic seizures work. When I watch things that have a lot of brightly-colored flashing lights my eyes hurt at most, but my brain seems okay and everything else seems fine. I don't understand how exactly this can induce a seizure in people and would like to know more. [link] [comments]  |

| How can "It's current that kills not voltage" and V=IR both be true? Posted: What I mean is that if voltage is proportional to current (given constant resistance across the person) then it seems meaningless to say that it's current and not voltage that kills. Unless maybe what they mean is that in these high voltage/low current circuits as soon as the circuit across the person is made the effective voltage across the person drops dramatically. Like for instance if the circuit has a lot of resistance in it then it can nominally have a high voltage drop across an open switch but as soon as it's closed the voltage drop falls to nothing. Or maybe this has something to do with quirks of AC? [link] [comments]  |
| Is it possible to create a solution with a net charge? Posted: Is there any way to isolate either an anionic or a cationic species in solution and then remove it? The only way I can think of removing a charged particle is by adding an equal amount of oppositely charged particles and reacting them out or by using a magnetic field and removing samples from one part of the solution.

| Posted: Since staring at the sun or a bright flashlight can damage your eyes, I'm wondering if non-visible light will do the same, and if I would notice any immediate effects if it happened. [link] [comments]  |
| So its been over a year since Philae landed, have we learnt anything new? Posted: Was reading old archives and stumbled on this; https://www.reddit.com/r/askscience/comments/2moow4/has_rosetta_significantly_changed_our/? The top response was that we hadnt had enough time to analyze the data. Have we now? Just finished reading this FAQ which outlined some of Rosettas goals and objectives, keen for the results!

| How do we know what the milky way galaxy looks like? Posted: As in shape, size, density, etc. I know that we haven't sent any satellites or probes outside of our home galaxy, and seeing as how we cant look at our galaxy from the "outside" like we can do to other ones, how is it that we can tell what it looks like?

| Posted: As far a I'm concerned the blood circulation transports the nutrients all over the body. But since the brain doesn't let any blood in I was wondering how food can effect the cognitive functioning. I've read stuff about omega fatty acids having positive effects, but don't really understand why. [link] [comments]  |
