Do all electrons, protons and neutrons have the exact same mass and volume or are there slight variations? Posted: 28 Jul 2017 05:49 AM PDT If the mass of an electron is said to be 9.10938356 × 10-31 kilograms, are there electrons that weight 9.10938356001 × 10-31 kilograms or 9.10938355999 × 10-31 kilograms? Or are they all absolutly, 100%, without a doubt exactly the same mass and volume? Is there a way to tell them apart? can we know if the electron/proton/neutron that we are observing is the same one that we observed before? submitted by /u/Vovabs [link] [comments]

Which is better for thermal protection/control, light colors or dark colors? Posted: 28 Jul 2017 05:56 AM PDT Videos online have said that commercial aircraft are white in order to provide thermal protection from the Sun, but the SR-71 flew much higher, thus exposed to far more radiation from the Sun than any other aircraft, and it was painted black, according to Ben Rich, for better thermal protection. So which is the true better option? submitted by /u/ripplecutbuddha2 [link] [comments]

Why are security features in government documents and currency made to fluoresce in ultraviolet light as opposed to infrared light? Posted: 28 Jul 2017 01:36 AM PDT A group of my friends who were Canadian were travelling abroad and I remembered seeing an image of the national passport on the site, imgur and how the pages 'glowed' in comparison to other passports so I decided to buy an UV flashlight online and sure enough we were amazed. But it brought me thinking about how more expensive ultraviolet lighting is and why would the government not cut costs by using features that fluoresced in infrared instead. Is it because of a practical issue involving science or a security issue? submitted by /u/femmejean [link] [comments]

What makes birds reptiles? Posted: 28 Jul 2017 07:52 AM PDT I am a biology major in college and it has been drilled into my brain that birds are reptiles, however many people don't agree.

If there is a little bit of time unaccounted for in a single day and single year on earth, why didn't we just create a unit of time that would have made everything accounted for? Posted: 27 Jul 2017 07:15 PM PDT For example, make the second just slightly longer to fill the gap. submitted by /u/dw_junkie [link] [comments]

Are stages of past rockets (pre-Space Shuttle Columbia) still in Low Earth Orbit as flying debris? Posted: 28 Jul 2017 12:12 AM PDT I know that for many months, if not years, that separated rocket stages and so on will linger in LEO as flying debris, although there are exceptions to that. Is it possible that certain parts of the Saturn V that carried out the Apollo 11 mission is still in the Earth's orbit for example? Not only that, but how dangerous will space debris be in the next 50 odd-years? I've recently been watching "Planetes", which inspired this question. submitted by /u/SpartanOfThePast [link] [comments]

How do we get advanced notice on earth of astronomical events like solar storms or the recent gamma ray burst? Posted: 27 Jul 2017 02:17 PM PDT As far as I know, these two events travel at the speed of light, and we obviously don't have any way to transmit data faster than that. Are there precursors to these events that reliable tell us they are coming? submitted by /u/elcapitanpdx [link] [comments]

What are those squiggly heat waves that sometimes radiate off hot stuff? Posted: 27 Jul 2017 06:28 PM PDT What is happening when those squiggly "waves?" appear?

Do microwaves interfere with WiFi signals? If so, how? Posted: 26 Jul 2017 03:14 PM PDT I've noticed that when I am reheating something in the microwave, I am unable to load any pages online or use the Internet (am still connected) but resumes working normally once the microwave stops. Interested to see if there is a physics related reason for this. Edit 1: syntax. Edit 2: Ooo first time hitting the front page! Thanks Reddit. Edit 3: for those wondering - my microwave which I've checked is 1100W is placed on the other side of the house to my modem with a good 10 metres and two rooms between them. Edit 4: I probably should have added that I really only notice the problem when I stand within the immediate vicinity (within approx 8 metres from my quick tests) of the microwave, which aligns with several of the answers made by many of the replies here stating a slight, albeit standard radiation 'leak'. submitted by /u/SplimeStudios [link] [comments]

What process does a Quantum computer undergo, at an atomic level, to "read" Qubits, and how do the Qubits collapse into the state which solves the task? Posted: 26 Jul 2017 09:47 AM PDT I'm doing a project on Quantum Computing and I've hit a bit of a wall when it comes to Qubits being in the "right" state as it were. As an example, if a Quantum computer were asked to find the two prime factors of a number (like in decryption/encryption), how would the Quantum computer read the selection of Qubits to give the correct solution? The only way I can think of this happening is to have a selection of logic gates that somehow collapse the Qubit into the correct state when observed; however, I'm not too sure how this actually would work with Qubits. Any overview/condensed answers would be as much appreciated as those which go into a more atomic/chemical depth about how it would all physically function. Cheers! submitted by /u/tooditoo [link] [comments]

[Computing] Why is Moore's Law predictably incremental? Posted: 27 Jul 2017 05:29 AM PDT Many people are familiar with Moore's Law, which states that the transistor count of high-end integrated circuits doubles roughly every 18 months. This, of course, is because the transistors themselves getting smaller and smaller. Looking at the past quarter century, we've seen the process size of high-end circuits shrink from around a micron to just a few nanometers. When you look at Intel's roadmap, they usually have a few die shrinks plotted out, years into the future. My stupid question is: Why is this so predictably incremental? I know they sometimes run into barriers that must be overcome, but barring those, what prevents companies like Intel from releasing chips built on a 500 nm process one year to a 45 nm process the next? If it's technological barriers, how are they so predictably overcome? Or is it just marketing, always wanting to give people a new, faster processor to buy? submitted by /u/CardassianNeckTrick [link] [comments]

what makes certain areas of the brain particularly suited to a task? Posted: 27 Jul 2017 04:14 AM PDT e.g. wernicke's area is associated with speech production.

Does humidity effect Digital Over the Air TV reception? Posted: 27 Jul 2017 03:47 AM PDT I have only a roof antenna. When OTA went digital it changed for the worse. I have had 2 new antennas installed since then and it seems the best reception is on very dry days. Is this just in my head? submitted by /u/lespaulstrat2 [link] [comments]

Would being underwater help survive a nuclear bomb? Posted: 26 Jul 2017 05:01 PM PDT If I jump in my pool, on the river near my house knowing that a nuclear bomb, or atomic or H-Bomb exploded around 10 km from my house, would I survive? The way I see it is that water will protect me from the heat, so then I will be able to surface up after the explosion and escape. submitted by /u/pandoracube [link] [comments]

My question is, why is it usually brown regardless of the color of the food eaten? submitted by /u/TimeCat27 [link] [comments]

What effect does cannabis use during pregnancy have on the offspring? Are there any associations with development of mental illness? Posted: 26 Jul 2017 08:30 PM PDT It seems that the most current literature is limited, since the majority of research and studies were done back in the 1980s when the potency of cannabis was much lower than it is today. I am researching this topic for a paper and any help would be greatly appreciated! submitted by /u/MsPoco [link] [comments]

Why does it take thousands of gallons of water to make a single pound of beef? Posted: 26 Jul 2017 07:05 PM PDT I have been looking into animal agriculture lately and I am bewildered by the amount of water it takes to produce beef.

Do more intense stimuli require more effort from our perceptual structures to observe? Posted: 27 Jul 2017 05:10 AM PDT What I really mean is, when a stimulus is more "intense", like when we're looking at a particularly bright scene or listening to something very loud, does the body have to expend more energy to perceive these high energy phenomena? I was thinking maybe your sensory neurons would have to go through/cycle neurotransmitters more rapidly, or that the neurons in the brain might have to fire more frequently, but I'd like to hear from someone who knows more about molecular cell biology than myself. submitted by /u/arborescere [link] [comments]

Do movement of electrons in an atom consume energy? Posted: 25 Jul 2017 04:13 PM PDT So, although an electron's location can only be expressed in probability, can we still say that it still moves from one place to another? I understand that not by following an orbit or something, but still it "moves" or "changes place" right? If so, would it be right to say that an electron (this moving particle) does not consume energy to move?

Why are the days of Jupiter, Saturn and Uranus so fast compared to the days of Mercury and Venus? Posted: 25 Jul 2017 06:32 PM PDT There is absolutely no apparent pattern, no symmetry in those numbers, and there is no logic as to why, at least in my limited capabilities of course. It seems the bigger the planet, the faster it rotates, the smaller the planet the longer it rotates, except for Earth and Mars? Obviously I'm not an astronomer nor a mathematician.

How is it that we can "hear" distance, as in, I know that a sound is coming from far away? Posted: 26 Jul 2017 05:30 AM PDT I thought of this while viewing a helicopter about a quarter mile away.

Why are double and zero quantum transitions not allowed in quantum mechanics? Posted: 26 Jul 2017 05:19 AM PDT I don't really know a lot about quantum mechanics but I found this as a side note in some lecture slides on NMR spectroscopy and got curious, since there was no explanation. submitted by /u/Tysanning [link] [comments]

The Uncertainty Principle is About a Fundamental Inability to Know Position and Momentum, Not an Instrumental/Technology Limitation. But aren't those indistinguishable empirically? Posted: 25 Jul 2017 03:58 PM PDT Basically what the title said. I understand it's a common misconception that the Uncertainty Principle is about instrumentation rather than a fundamental aspect of the universe, but isn't it empirically impossible to verify that? Meaning that a universe that has an Uncertainty Principle would be indistinguishable from a universe that has no UP, but instrumentation/measurement interference keeps you from measuring both to an arbitrary level of accuracy. Any experiment would give identical results for both possibilities, right? How is this resolved? Thank you in advance! submitted by /u/FormerDemOperative [link] [comments]

Is there any significant amount of rock/debris between solar systems? Posted: 25 Jul 2017 01:22 PM PDT In Passengers they're on an interstellar journey and would presumably chart a course avoiding stars/planets as well as they could. I'd think that'd be easy since space is so damn big. But this major plot point is them running into an asteroid field in the middle of nowhere and damaging the ship's computer.

How strange is it that the Higgs field has non-zero resting potential? Posted: 26 Jul 2017 01:03 AM PDT I'm asking about the state of modern understanding of the Higgs field. Are there solid, convincing, well-accepted explanations for why and how the Higgs has non-zero resting mass? Or is it more like a hint at some (or several) possible underlying mechanisms that aren't well-accepted?
