Is gravity equally distributed by a mass or are there hot spots where gravity is stronger in some areas and perhaps weaker in other areas? Posted: 07 Apr 2017 09:33 PM PDT Say there is a large mass. Is gravity equally distributed among this mass or are there "hot spots" so to speak?

Chemists and physicists, how can a volatile organic solvent like toluene have a higher boiling point than water, which is less volatile? Posted: 08 Apr 2017 04:04 AM PDT I find it quite odd that solvents like toluene or xylene will evaporate faster than water at room temperature, but still need to reach higher temperatures to start boiling.

Why does metal straighten right before breaking when a direct current is flowing through it? Posted: 08 Apr 2017 03:27 AM PDT Hi folks, Danish highschooler here. For my exam project, we have conducted an experiment where we tried to prove different types of resistances in metals by flowing a current through it. What we did was put current through a wire positioned in the air and measured the amount of current that went through it. I had to take evidence, so I filmed a slow-mo video with my camera and when we put through direct current I noticed that, when we increased the amp, the metal heated up and right before breaking it straightens it self. My first theory was it was the metal becoming so hot that it started to liquidize, but that didn't really make sense because the density of the metal would be higher and wouldn't cause it to snap. I have a video of the experiment here: https://www.instagram.com/p/BSlyYHrl6Em/ Can someone explain to me, why it snaps and why it straightens? Thanks in advance. submitted by /u/Cony777 [link] [comments]

What is keeping us from using materials like Carbon Nanotubes to create floating fabrics or textiles? Posted: 07 Apr 2017 08:06 PM PDT With technology creating material like this that is already far lighter than air and floats easily, what is the obstacle keeping us from using it to make fabrics that can float like this? Studios and designers would kill for fabric like that, so I can't imagine cost is the obstacle here, but I could be mistaken. submitted by /u/IAmA_Cloud_AMA [link] [comments]

Is "10" in binary pronounced "two" or "ten" ? Posted: 07 Apr 2017 07:35 AM PDT Instinctively i'd be inclined to say "ten", but then I thought about the word two and whether it refers to the notation "2" or the value "two units". Logically it would be two units, I mean counting can exist even without written notations. Therefore "10" in binary representing two units should be pronounced "two". But I'm still uncertain, it raises even more questions like whether A in hex is pronounced "ten" or "ay"... Is there even any definitive answer ? submitted by /u/Cynass [link] [comments]

Theoretically speaking, could antimatter be contained and stored? Posted: 06 Apr 2017 04:57 PM PDT My understanding of antimatter is limited, but what I do know is that if antimatter meets regular matter then they destroy each other. With that in mind, is it possible in theory for antimatter to be stored? For example, a chunk of antimatter suspended in a vacuum by a magnetic field. I imagine it would take a lot of power and technology we're nowhere close to now, but is it possible? I've seen antimatter used as weapons in a few sci-fi stories so it got me curious about how it would be stored/manufactured. submitted by /u/ParrotSTD [link] [comments]

Does there exist a number system which also introduces a "z" axis? The question "what is the square root of -1?" is a question about a real number that can only be answered by use of complex numbers.

Why is there almost no potential difference between two DC power supplies? Posted: 06 Apr 2017 05:28 AM PDT I'm not entirely sure if this is physics or an engineering question. I am interested in the physics. Embarrassing admittance, I actually have an undergrad degree in physics; apparently I didn't pay enough attention in E&M. I can't come up with a way to assign this a specific question as I feel there is something fundamental I am missing. Anyway, I digress, on to the explanation. I have two DC power supplies both wired into the same AC line that produce 24v. Here is an image of my horrible wiring. I imagine that the circuit diagram probably looks like something along these lines. I was playing around and attempted to wire a light from the - side of one power supply to the positive side of another. The light didn't light and I found this confusing. So I broke out my volt meter and measured the potential difference between the positive side of one power supply to the negative side of the other. This is what I saw. What? I found this extremely confusing and I'll explain why shortly. I randomly cranked up the sensitivity of my volt meter and took the measurement again. This time I did measure a potential. That's millivolts, which I have no explanation for. Even more unusual was that this oscillated between +- 40 millivolts. What the heck? Why is this oscillating, I thought this was DC? Like a good little scientist I decided to just measure every possible combination of connections between the two devices producing this table that just leaves me confused. (Note these are maximum potentials as they all oscillate for some reason). My understanding of things was that both of these power supplies generated a potential relative to ground (grounds are tied BTW). All the happy little electrons pooled at the negative DC terminal ready to travel off to a potential difference. Before doing this little experiment, I would have assumed that there would be a current flow from the negative of one power supply to either the positive OR the ground of the other. There isn't. Apparently my understanding of the physics here is extremely flawed. What the heck is going on? My horrific list of questions I don't know how to answer: Why do I measure almost zero potential difference between the two power supplies? Why does it oscillated on a DC system? Why am I measuring a potential difference between the two positives or the two negatives? Why is that potential difference the same magnitude as the potential difference I measure between - and positive? Why do I measure a potential difference between BOTH positive and ground AND negative and ground? This has been bothering me for about a week and I have discussed it at length with two electrical engineers neither of which could give me a good explanation. So thanks for putting up with my rant and thanks for the help ahead of time :) Note: This could probably be classified just as easily as an engineering question and it may have an engineering answer that I am not aware of, but I feel it's important to note that it's the physics I am particularly interested in. submitted by /u/JMile69 [link] [comments]

Why is it so difficult to span large bodies of water? Posted: 06 Apr 2017 04:57 AM PDT For example I was reading about the troubles with bridging huge fjords in Norway and I was thinking: "Why can't we just build floating bridges?" Surely its difficult, but not impossible with modern technologies. But, I realize I don't know anything about modern structural technologies.

Posted: 05 Apr 2017 06:45 PM PDT I understand that each half of the brain contains roughly 50 billion Neurons, and each neuron has between 10,000-15,000 neural synapse connections to other neurons for a total of 5,000 Trillion neural synapse connections in each half of the brain, while the part of the brain (Corpus Callosum) that connects the two halves and feeds information back and forth only has 150-250 million fibers in it. Is this in effect a stovepipe for information that is not capable of transferring the vast amount of information back and forth between the two brain halves? Would beefing up the Corups Callosum with more fibers increase the amount of information that could be transmitted back and forth between the two halves of the brain? submitted by /u/DopeBoySpaceMagic [link] [comments]

Have there been any big updates since the Higgs boson was discovered? Posted: 05 Apr 2017 08:55 AM PDT Searching "higgs boson update" on google gives an April fools article from 2016 as the top result. Have there been any updates on the Higgs boson since it was discovered? Was it confirmed to be the Higgs boson that was originally predicted, or did it turn out to be some other Higgs-like particle? Have the initial measurements been refined? submitted by /u/CH31415 [link] [comments]

Why does liquid form a parabolic shape when spun in a container? Posted: 05 Apr 2017 04:28 PM PDT I just watched a PBS Space Time video (so I guess the source is credible) in which the guy mentions a liquid mirror made of mercury that does 6-8 revolutions a minute and thus creates a parabolic mirror to focus light. Does this happen to all liquids in a container? If I'm spinning my wine in a glass does it always want to take up a parabolic profile? submitted by /u/i_like_pringles95 [link] [comments]
