| If dark matter is found and proven, how much would that change physics and math? Posted: 07 Sep 2016 11:55 PM PDT I don't have a math background so the in depth answers will be above me, but I just wonder if a discovery like proving dark matter will have a fundamental shift in math and physics theories?

| Are there any Laws of Biology? Posted: 07 Sep 2016 09:56 PM PDT Boyle's law is an example of a law of thermodynamics. Hooke's law is an example of a law of physics. The Pythagorean theorem can be described as a law of geometry. Are there any laws of biology? Or is the interaction of cells and molecules on a biological scale to complex to have specific laws?

| Can a buckyball shape be formed with any other elements aside from Carbon? Posted: 07 Sep 2016 10:32 PM PDT Title. I was watching Big Brother and they had some made up element called 'vetonium' which was shaped like a big buckyball. Which got me to wondering if there actually are any other (real) elements or molecules aside from Carbon that can form a buckyball shape. And if only Carbon can form the buckyball shape, why is this? What's so special about Carbon? Hopefully my question isn't too obvious/stupid. I don't know much about chemistry beyond first year undergrad courses. [link] [comments]  |
| Posted: 08 Sep 2016 06:11 AM PDT Read an article about the way most of the exoplanets are spotted through dimming when they traveled in front of the star, and it made me wonder if another big planet could alter it's orbit to not make it travel in front of the star when viewed from earth. (making it fly "below" so to speak) Are most orbits stuck on a central plane like ours or are there different kinds? [link] [comments]  |
| Posted: 08 Sep 2016 03:00 AM PDT Seeing the TIL about the viscosity of the earth's mantle, it got me thinking. How are we able to have so much information about what makes up the inside of the earth when we have never been able to drill 'very far' (12km falls into nothing scale-wise). Are these theories, or is the knowledge of the core based on strong facts? [link] [comments]  |
| Posted: 07 Sep 2016 09:21 PM PDT The wiki page is a bit confusing regarding that, if it's the same phenomena but at a different frequency/wavelength then the same principles should apply for antennas and diodes but at the same time it seems as if the term "electromagnetic spectrum" is an umbrella used to name many different things with wave-like properties in common.

| Posted: 08 Sep 2016 07:14 AM PDT Please dont delete this, part of the question. also why do people keep saying that the emdrive should generate no thrust when people who experiment record thrust (albeit a small amount). [link] [comments]  |
| Why have the ISS in orbit instead of on the moon? Posted: 07 Sep 2016 11:56 PM PDT It just seems like logical progression to me and makes sustainability easier. [link] [comments]  |
| How does one accurately determine the bond angle of the hydrogen atoms in a molecule of water? Posted: 07 Sep 2016 07:33 PM PDT Recent reading on the properties of water led me to find some pretty outlandish statements concerning water's effect on it's environment when the bond angel is made more obtuse. Is this even possible? [link] [comments]  |
| Posted: 07 Sep 2016 09:27 PM PDT I've been reading on affective neuroscience and the biological determinates of well-being lately. Specifically, the book The Emotional Life of your Brain by Richard Davidson has captivated me. However, his studies relied primarily on MRI and fMRI scans; and thus, they outlined brain regions that were only (albeit, miraculously) correlated to different emotions and 'emotion styles.' Are we able to observe and quantify emotion on a more precise, say neuronal or molecular, level? Would this knowledge be better suited to fight neurological conditions (i.e. depression, schizophrenia)? Please let me know of any knowledge or literature that I may absorb; one of my current academic pursuits is to learn the absolute fundamentals of emotion and well-being. [link] [comments]  |
| Depth of Field and Virtual Reality, How Does the Human Eye Experience DoF in VR? Posted: 07 Sep 2016 06:18 PM PDT A lot of developers right now are trying to make DoF "work" in Virtual Reality. The basic setup right now is two screens, set a few inches from the eyes, with a lens for each eye focused to infinity. As I understand it, DoF is something that the eye "does", not a property of the light coming to the eye, and developers don't need to mimic it with software or hardware so long as the eyes are fooled into thinking that real distance is involved. I also understand that the human eye is not a simple camera, and that DoF is more complex than just the focus of the lens, I've even found research that says DoF is not affected by the diameter of the pupil in the human eye. DoF is just one byproduct of accommodation and should not be applied as liberally as game developers have in traditional non-VR titles. I think they're barking up the wrong tree, but I don't know enough to say either way and I'm not really keen on taking lessons on the human eye from game developers. What is DoF as experienced by the human eye, really, and is it something that needs to be built into a VR headset? [link] [comments]  |
| Why do engines run more efficiently when hot? Posted: 07 Sep 2016 07:13 PM PDT My car gets get at least ten miles per gallon more when the engine is at optimum operating temperature. Why is this? I understand the oil may become less viscous but would that have much of effect? I can't find any good answers on google. [link] [comments]  |
| Do individual moving charges create a magnetic field? Posted: 07 Sep 2016 11:37 AM PDT Relativity explains the forces between two current-carrying wires in terms of relativistic length contraction, but what about two electrons next to each other? In their rest frame, there is only the electrostatic force, but for observers moving relative to the charges, there would be the additional lorentz forces. This cannot be explained by altering the profiles of the fields because then you would have to do the same thing for the charges in the current-carrying wire and end up with double the force. One from the fields being altered and one from the length contraction effect. Does this mean that individual moving charges do not produce a magnetic field? [link] [comments]  |
| Posted: 07 Sep 2016 06:23 PM PDT I feel like I'm missing something obvious, but I can't quite put my finger on it. A linear combination of solutions to the Schrodinger equation is also a solution to the Schrodinger equation, but I never really understood the significance of that since we always seem to speak of electrons being in one of the basis eigenstates. Maybe there's a reason why I don't remember or just never dealt with, but I was having googling up an answer. What my question then boils down to is: If a linear combination of eigenstates is perfectly valid as an eigenstate, why can't an atom in the ground state have an electron transition to a fractional sum of eigenstates? Why do they only absorb and emit photons that transition them into other pure basis eigenstates? For example carbon absorbing a photon to move an electron from 2,1,0 to 1/2(2,1,0 + 3,1,0) or some other sum of fractional eigenstates so why are spectral lines ultimately quantized? I just don't know the right angle to come at this from. [link] [comments]  |
| Why are the wavelength intervals in some radio tuning interfaces not spaced in a consistent fashion? Posted: 07 Sep 2016 03:17 PM PDT I see AM-FM radios with tuning interfaces like this all the time: http://nevadanewsandviews.com/wp-content/uploads/2014/11/a2.jpg Usually at least one of the broadcasting bands (FM or AM) have their numbers in irregular intervals, not linear, or not even apparently logarithmic in progression. Sometimes the FM band may have the intervals evenly spaced but the AM spacing is more "erratic" (especially the spacing between 540hz and 600khz, then a 100khz change across the same distance). What establishes the reason for the irregular spacing and granularity? Are some wavelengths naturally more difficult in certain regions to broadcast signals without interference? Are the less granular areas mostly allotted for other, non-public and non-commercial purposes? [link] [comments]  |
| In a hyperbolic orbit, what is the shape of the larger body's orbit? Posted: 07 Sep 2016 03:00 PM PDT Suppose there are two bodies, e.g. a star and a planet. The star is initially at rest, and the planet has at least escape speed tangential to the star. That is, the planet is at the closest point in a hyperbolic orbit. What path does the star's "orbit" trace out after infinite time passes? Assume Newton's law only and no other bodies in the universe. Thanks for your help. [link] [comments]  |
| Are birds really dinosaurs? And if so, what's the proof? Posted: 07 Sep 2016 08:00 AM PDT We are doing evolution in Biology class right now, and my teacher won't believe me that birds are dinosaurs, and by that extent reptiles. Am I wrong? It would be really awesome if you could give me sources, because according to my teacher Wikipedia is categorically wrong. [link] [comments]  |
| What happens in my brain when I hear my name vs when I hear someone else's? Posted: 07 Sep 2016 06:12 PM PDT |
| Why can an isotope between two stable isotopes be unstable? Posted: 07 Sep 2016 10:54 AM PDT S-34 and S-36 are stable, but S-35 isn't. This is one of the dozens of examples of this 'phenomenon,' but do we know why it happens? [link] [comments]  |
