| How does "Calorie-in - Calorie-out" and "You only burn fat after x Time of Exercise" fit together? Posted: 11 Mar 2018 04:40 AM PDT I often learned that we only burn fat, and thus loose weight, after 30 mins or so of exercise. (Because before that the body uses some other energy source). Then the same people tell me, that the only thing that counts is the Calorie-in / Calorie-out balance. So at least for my brain these two assumptions won't fit together. If I exercise for just 20 min I might not burn fat but still use Caloriens, so later in the day my body should rely on the fat as an Energy source. So I might not burn fat while exercising but, if "Calorie-in - Calorie-out" is true, I should still loose weight. This question is bugging me for years and all people I talked too, including my Sports Teacher, just keep repeating the thing about the energy-sources, and completely miss my Point. So I hope the question was clear enough and you can finally enlighten me and / or show me where my thinking error lies. [link] [comments]  |
| When a woman gets a c-section during birth, does labor just turn off? Posted: 11 Mar 2018 12:14 AM PST I guess I always imagined labor to be a process that can't stop once it's started, but at what point does your body send the signal to the brain to stop labor when a c section is performed?

| Can terminal velocity slow down a falling object? Posted: 11 Mar 2018 03:45 AM PDT Everyone on this subreddit knows what terminal velocity is. If you drop an object, it will accelerate (due to gravity) to a point where it can no longer accelerate (due to resistances, such as air resistance), thus reaching its top speed through natural falling. However, what if the object is initially thrown downwards faster than its expected terminal velocity? Would the upwards resistances slow the object until it reduces the velocity to the object's expected terminal velocity, or would it stay at it's thrown velocity? [link] [comments]  |
| Posted: 10 Mar 2018 12:02 PM PST When looking at the gas giants in the Solar System, they appear to be colored in order, matching an increase in frequency. Jupiter is reddish, Saturn yellow, Uranus a light blue with a hint of green, and Neptune a deep blue. Is there any reason for this, or is it a mere coincidence? I understand that the colors of the planets do change sometimes. Jupiter can become yellower, for example. But it never becomes blue. I did some searching, both around the internet at large and this subreddit in particular, and couldn't find anything commenting on this phenomenon. I hope this question hasn't been asked before. Thanks in advance! [link] [comments]  |

| Posted: 11 Mar 2018 07:22 AM PDT If that's a confusingly worded question, it's because I'm a little confused myself after watching this PBS SpaceTime video. So I gather that mass, as a property, is just the natural consequence of energy interacting with the Higgs Field - not with the actual Boson itself. Maybe it's more accurate to say that mass appears to exist when particles are slowed down by the Higgs Field? I'm not sure. But that all begs the question of what does the Higgs Boson actually do? Is it a force carrying particle like the other bosons? What force would it even carry? Or am I completely misunderstanding everything about this? (Bonus question - does any of this tie into why the speed of light is related to why or how energy can become mass in the first place? Because that's what I was actually trying to figure out when I went down this rabbit hole.) [link] [comments]  |
| After accounting for supply chain, what's the cleanest power source humans have? Posted: 11 Mar 2018 12:23 AM PST I've often heard that nuclear is actually the cleanest and most efficient power source we have after accounting for the supply chain impacts. Like solar's supply chain (getting the minerals from the earth) is really expensive, damages the ecosystem due to mining, and causes tons of pollution. I want to know if this is actually true. or at least be directed to sources that could help me answer this question. Thanks! [link] [comments]  |
| Do subliminal messages really work? Posted: 10 Mar 2018 09:11 AM PST I just downloaded a program called "Subliminal Messages." It claims that by flashin text too fast for me to read it can help me do things like quit smoking, have more confidence, etc. Is this true? [link] [comments]  |

| Would a Ball of Yarn solve the Coastline Paradox? Posted: 11 Mar 2018 12:24 AM PST I just watched the RealLifeLore video about the Coastline Paradox which says coastlines are like fractals. Is the perimeter of a country really infinite / could you hypothetically roll a ball of yarn around a landmass and then measure it to find the true length of coastline? Seems very counterintuitive.

| Posted: 10 Mar 2018 07:20 AM PST Unfortunately I got into a debate with a classmate over the whole "microwaved water kills plants" myth. I see that Snopes has debunked it, and the whole idea doesn't fit with my basic knowledge of science. But my classmate came back with the below journal article, and it's way above my pay grade. Is there anything to it? Is this study credible and do its conclusions actually support the assertion that microwaves can change the chemical or physical properties of water? [link] [comments]  |

| Posted: 10 Mar 2018 01:04 PM PST As an example, why did the Colonials from England lose their British accents as time went by if these colonists retained their homogenous way of life. I'm of course talking about a generational change. I don't necessarily mean the original people's accents changed through their lifetimes. [link] [comments]  |
| Posted: 10 Mar 2018 02:10 PM PST Hi all, just recently started using IR and Raman spectrometer, and I know they receive signal of vibrational energy emitted from molecules of the sample.. However, I cannot get my mind around why they are vibrating in the first place? [link] [comments]  |
