Planck's quantum hypothesis proves that a body can't emit radiation beyond a certain frequency, but this still means that it will emit waves in ALL THE POSSIBLE FREQUENCIES below this limit. So wouldn't the body still be losing energy at an infinite rate?

What is the difference between quantum uncertainty and ordinary uncertainty? Posted: 06 Nov 2015 05:34 AM PST In an electron diffraction experiment, we can shoot electrons one at a time through a grating, and they will make a diffraction pattern, showing that the electrons are really waves. This diffraction pattern is a statistical distribution of the electron wavefront at the detector, and the grating helps to illustrate the connection between uncertainty in position and momentum. If i make macroscale experiments, i will also get statistically distributed results. If i make different experiments on the same sample, the order of experiments is usually important. With better methods i can reduce the interaction between the experiments. Is the Heisenberg uncertainty just the theoretical lower bound on this interaction, or are there other differences as well? submitted by ThrowAway9001 [link] [6 comments]

Why are tornado watches and warnings almost always in the evening? Posted: 05 Nov 2015 04:24 PM PST Like, seriously. Most tornado warnings and watches I've lived through are around dinnertime.

SanDisk released a 200GB Micro SD. What might be the reason, technologically, for such an odd capacity? Posted: 06 Nov 2015 03:20 AM PST I saw on Amazon that SanDisk has a 200GB Micro SD. It seems really odd as usually storage is usually sold in sizes that are power of 2's (8, 16, 32 etc.) I'm curious to know if there is any technological reason behind this.

What is the speed of conductive heat? Posted: 05 Nov 2015 10:46 PM PST In another thread here, I posed the question of the speed of conductive heat (not radiative heat, which is the speed of light). But I got no definitive answer, some said the speed of sound, others said "much faster" due to electrons somehow, whilst others said other things. So what is the speed of conductive heat relative to materials, is it different for different materials (I expect it is), and how do different factors affect it? submitted by thetechniclord [link] [2 comments]

Creating drinking Alcohol from hydration reactions instead of Fermentation? Posted: 05 Nov 2015 01:57 PM PST I was wondering why we always use fermentation to form ethanol instead of a hydration reaction with ethene. To me it seems a lot more simpler to just do this instead of moonshining like a lot of people do, playing around with different ratios of sugar and yeast and sometimes ending up with poison. It seems like a safer 1 step process to me, am i wrong? submitted by Thatotherhippy [link] [16 comments]

Why does the aortic valve open and close at different pressures? Posted: 05 Nov 2015 08:56 AM PST Looking at all sorts of different pressures volume loops, the opening and closing pressures of the aortic semi lunar valve are always at different pressures. Wouldn't the pressure needed by the ventricle to force it open be the same as the pressure needed by the aorta to force it closed? submitted by touches_butts [link] [2 comments]

Why does this rainbow appear to be being 'revealed' by the mist? Posted: 05 Nov 2015 03:36 AM PST I was on /r/gifs earlier and saw this gif. The mist forms a rainbow, but as the mist moves, the rainbow follows the same arc as it initially did, as if there was one continuous rainbow that was being 'revealed' by the mist as it drifted across. So why does this happen? Shouldn't the rainbow just appear to be shifted across as the mist moves? submitted by TheTimeNomad [link] [23 comments]

I've heard the electron described as a point particle - since it has mass, wouldn't that make it a black hole? Posted: 04 Nov 2015 05:47 AM PST Or is that proof the electron has a radius, since it would evaporate if it were a black hole? submitted by erythro [link] [34 comments]

Does a swapping of bases between the strands count as a single nucleotide polymorphism? Posted: 05 Nov 2015 05:27 AM PST I was wondering whether someone could explain to me if a change in bases could be considered a SNP even if the bases had just swapped. For example if I had DNA running: A C A T G T G T A C or A C T T G T G A A C Would the change of the A and T be considered a SNP.

What is the difference between a computer verifying the answer to a problem and solving the problem? Posted: 04 Nov 2015 09:46 PM PST Apparently the fundamental basis of the P vs NP problem is, according to wikipedia: "whether every problem whose solution can be quickly verified by a computer can also be quickly solved by a computer."

What if you fell into a collapsing black hole? Posted: 04 Nov 2015 10:00 PM PST I know falling into black holes comes up quite a bit here, but I though of a different angle on it that I didn't see addressed after a quick search. So, an astronaut falling into a static black hole might not notice when she passed the event horizon (let's assume it isn't full of radiation for now), and would continue falling until tidal forces ripped her apart. But a distant observer would see the astronaut get "frozen" at the event horizon, before getting red shifted out of existence. I'm ok with their different perspectives of what happens here. But... let's assume this black hole eventually evaporates by Hawking radiation, like we expect all black holes will. I've read that the outside observer now sees the astronaut fall into the black hole at the moment it evaporates, or alternately that they see the astronaut is burned up. But from the perspective of the astronaut inside the black hole, when does the black hole evaporate? I mean, I assume she will be killed pretty quickly, but say from the perspective of her electrons. Does she never encounter the evaporation, because time is curved so far inside the black hole that the event horizon can't be in her future? Or would the event horizon "catch up with her" as it shrank down? Is the answer going to require distance scales so small that we need a quantum theory of gravity to say anything about it? Bonus points if you can tie this into the information paradox. submitted by AugustusFink-nottle [link] [6 comments]

How can a black hole's singularity be a "point", wouldn't that violate the pauli exclusion principle? Posted: 05 Nov 2015 07:16 AM PST (my bad layman understanding) As I understand it, a singularity is a "point", and a "point" is "sizeless", meaning that all that compressed mass will occupy the same space, which violates the pauli exclusion principle... what is wrong with my understanding? submitted by HippyYoHippyYay [link] [4 comments]

Does a black hole form from the inside out, outside-in, or all at once, when a star collapses? Posted: 04 Nov 2015 01:34 PM PST From the outside-in doesn't make sense, because the singularity should be a point, not a shell. If the black hole forms from the inside out (ie the core of the star first), then we should never see it grow because the rest of the collapsing matter will take forever to fall into the singularity due to time dilation, correct? Or, does the event horizon suddenly appear at the instant of collapse, making everything inside instantly invisible to the outside? submitted by 1BitcoinOrBust [link] [12 comments]

Why can't my brain correct my blurry vision? Posted: 04 Nov 2015 12:33 PM PST I know that brains can correct for all kinds of weird visual problems, like filtering out blood cells and vessels and people with one eye being able to perceive depth, and I've even read about people being asked to wear goggles that turned the world upside-down developing the ability to interact with the world as normal. So why is it that my brain can't deal with the blurriness caused by my nearsightedness and mild astigmatism? submitted by onlypostscalligraphy [link] [12 comments]

From an outside observer, does matter pass through a black hole or not? Posted: 04 Nov 2015 06:00 AM PST I've seen examples about black holes, objects passing through them; the most common one: a clock passing through a black hole. From the clock's perspective, it just passes through the black hole like nothing, I think; but, from an outside observer, it will slow down as it approaches to the black hole, and it will reach the point where it will stop because the gravitational force is so strong that dilates the space and time. So, if matter will eventually stop, why don't we see matter placed at the middle of black holes? Does matter really pass through them or not? submitted by feute [link] [1 comment]

Can a side effect of global warming also be more extreme winters? Posted: 03 Nov 2015 11:48 PM PST For some reason I've always had the idea that if the summers are getting hotter than it would follow that the winters would be colder. I'm not sure where I picked up this idea or if I just assumed it. I don't know if this makes sense or is even correct, but it's one reason why when I hear arguments against climate change talking about how it snowed a lot last winter so global warming can't be real, it just doesn't make sense to me. Can anyone tell me if this actually happens because of global warming? If so, what causes it? submitted by scamlet [link] [18 comments]
