Why does turning on a second light not make a room seem twice as bright? Posted: 05 Apr 2018 02:52 PM PDT When you turn on a light in a dark room, it obviously gets much brighter. But if you turn on a second, identical light, the difference in brightness is almost indiscernible. Why? Is it just because of our pupils constricting more, or is something else happening? submitted by /u/OddOliver [link] [comments]

Why do terrestrial objects in space move so slowly compared to the speed of light? Posted: 06 Apr 2018 07:51 AM PDT The fastest asteroid on record was moving at only 64,000 which is about Earth's orbital speed around the sun. That's fast but stars close to the super massive black hole in the center of our galaxy are moving as speeds close to 15,000,000 mph. That's fast but only about 2% of the speed of light. There are billions of black holes accelerating objects as they pass close by, and there is no drag in space other than perhaps flying through a gas cloud. Could Earth some day get hit with an asteroid shot from our galaxy's center moving at say just 5% of the speed of light? I imagine a five mile wide object moving at 35,000,000 mph would never be detected and would release enough energy to annihilate the planet. submitted by /u/joecooool418 [link] [comments]

Are the current health food trends such as non-GMO and organic better or worse for the environment and sustainability? Posted: 06 Apr 2018 07:44 AM PDT Curious if there are bigger picture problems we are disregarding when consumers demand organic and non-GMO. It seems like that's all you can find in the stores these days, whether you actually want it or not. submitted by /u/xupaxupar [link] [comments]

What's the minimum density required for a gas to make us able to hear/make a sound? Posted: 06 Apr 2018 02:31 AM PDT So I ask this from a "human" standpoint. I'm talking about sound we're able to hear. Thanks! submitted by /u/Tiranyk [link] [comments]

What are the 3% of climate change papers which disagree with anthropomorphic change? Posted: 06 Apr 2018 04:48 AM PDT We often hear that 97% of peer reviewed papers agree with the common stance on climate change: that it is happening and human activity is the cause. I'm interested in the other 3%. Are they all old? Or very narrow in scope? Or do they have interesting things to add to the conversation? Is there anything similar in other areas of science? Surely there aren't 3% of physics papers arguing against quantum theory, or medical papers in favour of homeopathy. submitted by /u/dargh [link] [comments]

How can Astronomers calculate the orbital speed of stars in different galaxies? Posted: 06 Apr 2018 05:49 AM PDT One of the main reasons (I believe) that astronomers believe dark matter exists is because the stars in galaxies orbit too fast to be held in orbit only by the gravity of the visible matter. How can they tell they speed orbital speed of object so far away? Surely their movements would be imperceptible. submitted by /u/Dremble [link] [comments]

How come it took so long for humanity to develop the concept of interchangeable parts? Posted: 06 Apr 2018 06:57 AM PDT https://en.m.wikipedia.org/wiki/Interchangeable_parts There was evidence of interchangeable parts over 2,000 years ago, but it never caught on for some reason. Why did it take so long? I feel like there must've been a bunch of scientists at the time who, afterwards, said "Gee, I wish I'd thought of that!" As a side note, it's often said that you can't make something that fits all of these requirements, but interchangeable parts are better, cheaper, and faster. submitted by /u/theorymeltfool [link] [comments]

Can a spaceship descend slow enough to Earth that it wouldn’t encounter the intense heat generated upon reentry? Posted: 05 Apr 2018 10:08 PM PDT If a craft was able to decelerate to a slow enough speed, could it gently fall back to earth using vector rockets (or something) and main thrust to keep the descent slow enough or would it be unable to punch through the Earth's atmosphere? Less heat and constant radio communication are cool, right? (Pun intended). submitted by /u/hartzonfire [link] [comments]

Have the giant trash patches of the ocean (some maybe the size of texas) developed ecosystems? What animals are part of that? Posted: 05 Apr 2018 01:23 PM PDT After seeing this https://news.nationalgeographic.com/news/2009/09/photogalleries/pacific-garbage-patch-pictures/photo4.html a while ago I have become curious as to how deep ecosystems that exist because of the garbage patches are an what they look like. It seems like there are lots of places for small animals to hide, which means there could be a lot of food for potential predators. And since its all garbage I imagine there is a decent amount of nutrients that at least at one time have clung to the garbage, which can be used as food. I am not supporting litter. I am just wondering what out waste has created. Thank you. submitted by /u/GilgameshWulfenbach [link] [comments]

Do nightclubs and other places the play loud music suffer from more structural issues than other buildings? Posted: 05 Apr 2018 06:52 AM PDT The question came to mind when I was in a nightclub recently and the music was so loud I could literally feel the walls vibrating with it when I touched them. I don't know much about engineering but I can't imagine that's healthy for the structure. submitted by /u/TehBigD97 [link] [comments]

Are overpasses designed to withstand over-height vehicle strikes? Is it based on size? Posted: 04 Apr 2018 04:26 PM PDT You see dump trucks with beds up and over height trucks striking overpasses. Are they designed for that? Is there a "rating" or standard? Are overpasses often structurally totaled from strikes? submitted by /u/AntAPD [link] [comments]

How do we know that other galaxies do not consist of antimatter? Posted: 05 Apr 2018 07:23 AM PDT There are three things that you often hear about antimatter: It is the exact opposite of normal matter and when a matter-particle meets its antimatter-counterparticle, they annihilate each other resulting in the emission of a photon. Antimatter particles behave to each other just like regular matter particles do. Antimatter is rare, but we don't know the reason for that. That last statement always confuses me because I don't know how we can know that. Well of course antimatter is (luckily) very rare on our planet, because antimatter particles are easily annihilated through regular matter here. You can also assume that it's very rare in our solar system or in the whole milky way for that reason. But if it normally behaves the same as regular matter does - how can we know that galaxies far away, take andromeda as an example, do not consist of antimatter? Wouldn't an antimatter star emit the same light as a regular star? Because as far as I know, the photon has no antimatter-counterpart (or is identical to its antimatter counterpart). And if there were whole galaxies consisting of it, we couldn't assume that it's rare anymore, that could mean that there is equally much antimatter as there is regular matter or that there even is more of it Is there a way to distinguish matter from antimatter while observing it from far away? Or did I miss something else? Maybe I misunderstood the whole concept. Well that's my question, I would be thankful for any answer. submitted by /u/Peraltinguer [link] [comments]

Would my beer gut look different if I never wore pants my entire life? Posted: 04 Apr 2018 03:42 PM PDT Does our clothing and how it fits have any effect on how adipose tissue develops and accumulates? If so, how does our body store fat around tight fitting clothes (like the waist of my pants)? submitted by /u/qneville [link] [comments]

During the Mass extinction of the Dinosaurs how long would it take? Posted: 05 Apr 2018 06:08 AM PDT When the asteroid hit how long would it take to say wipe them out completely weeks? Days? Hours? submitted by /u/Redditor-boi [link] [comments]

Is there any ecological danger in mining or otherwise destroying salt flats? Posted: 05 Apr 2018 06:49 AM PDT I saw a post about lithium mining and how salt flats are a popular source. As far as I know, salt flats are of virtually zero importance to the ecosystem, and possibly the same for barren arctic areas (except for the few animals that traverse it). Could we strip and mine to our hearts content and expect no significant consequences? Note: I'm dismissing air pollution and assuming we don't dump waste into water. submitted by /u/SirNanigans [link] [comments]

From a neurological perspective, what is intelligence? Posted: 04 Apr 2018 08:34 PM PDT Both my parents are quite bright (Dad is a doctor who does research. Mom is a nurse.) Several years ago, I had my IQ tested and was told that I have something called Nonverbal Learning Disorder. My verbal score was high, but most other aspects of my intelligence were average or below average, indicating that certain parts of my brain work more efficiently than others. One would assume that two intelligent parents would have a child of equal or greater intelligence, but for me this wasn't the case. From a biological perspective, what is intelligence, and how does an "intelligent" brain differ from one that's average or slow? submitted by /u/pmmecoolpianopics [link] [comments]

How do we know the universe is still expanding? Posted: 05 Apr 2018 01:30 AM PDT I am familiar with Hubble and his namesake telescopes discoveries about the red-shift witnessed in distant galaxies and that the further the galaxy the faster they appear to be moving away relatively to us. Yet I find it curious that closer galaxies do not show this, like Andromeda. Yet the galaxies we do observe it from, we are seeing light that is millions or billions of year old potentially, so how do we know it is still happening? submitted by /u/Benn42 [link] [comments]

Why are antibiotics used more than bacteriophages? Posted: 04 Apr 2018 11:58 AM PDT We know that antibiotics isn't going to last long as bacteria find ways to become immune to it. So my question is, why hasn't the use of bacteriophages become a medical practice. Just like regular viruses, they seem to mutate after they leave they made contact with the bacteria. So just like the situation with us humans and the flu, it wont be easy for bacteria to mutate and become fully immune "Bacteriophage A" because there would be many versions of it. submitted by /u/punkamania101 [link] [comments]

What happens when you slip and hit your head and go unconscious or get concussed? Is there a difference between the two? What goes on in the body/brain? Posted: 05 Apr 2018 03:37 AM PDT Someone slips and hits their head on something, gets punched really hard, or just takes a strong force to the head, what is actually happening? Are they unconscious or concussed? What's the difference internally? What's the differences of how the body responds, like what's the fencing response or the abnormal positioning that happens after something like that? Are their eyes open? Are they open but rolled back in their head? Are their senses basically turned off or are they in like power save mode or something? Particular in combat sports where fighters go into fencing response, what's different between them and someone that hits their head and has to go to the hospital and have surgery to get part of their skull taken out to relieve pressure? One who slips, loses consciousness, and is taken to the ER, are they treated like an athlete would be or if they're unresponsive do they go straight to surgery? submitted by /u/UghThisIsBullshit [link] [comments]

How can a neutron star, as something made purely out of neutrons, have any kind of magnetic field ? Posted: 05 Apr 2018 07:19 AM PDT I am mainly refering to this. The video explains what neutron stars are most likely made of, but if they are only made of neutrons, how can they have any magnetic properties ? Aren't protons neutral in charge ? submitted by /u/ZweiEuro [link] [comments]

Why is there usually a roughly 50/50 male to female ratio? Posted: 04 Apr 2018 03:45 PM PDT An asymmetry between male and female members of many species is that males can reproduce quickly and with many females, while females can only have one (or so) baby at a time. This puts a scarcity on available females, leading to various kinds of sexual selection. Wouldn't a more straight forward strategy be to give a preference to female births over male? I assume that if you did the math about the optimal male to female ratio to maximize reproduction, if wouldn't be 50/50 but more like 20/80. Is there some reason that it's difficult for a biological system to vary that? What's special about 50/50? submitted by /u/harumphfrog [link] [comments]

Can you tell by looking at power lines which way goes to the customers and which way is the power plant? Posted: 04 Apr 2018 01:32 PM PDT I got thinking of this in a Walking Dead type post apocalypse scenario where you might be ambitious enough to try to restart a power plant. If you came upon a power line, and the power is out, would you be able to tell if you should go left or right to get to the power generation plant? submitted by /u/cmuadamson [link] [comments]

How can waves of different frequencies be orthogonal to each other yet interfere either constructively or destructively? Posted: 04 Apr 2018 10:03 AM PDT I think I am missing something here. In a traditional geometric view, two orthogonal vectors, say a and b, cannot interfere with each other. For example, i, j, k are orthogonal basis of Eucledian space, and each point can be represented through a certain combination of these. Fast forward to waves: sine waves of different frequencies are orthogonal to each other (hence fourier decomposition is even possible in the first place?), but they still interfere with each other. Sound waves are a perfect example. What am I missing? submitted by /u/ezusername22 [link] [comments]

If someone becomes immunized, and you receive their blood, do you then become immunized? Posted: 03 Apr 2018 07:10 PM PDT Say I receive the yellow fever vaccine and have enough time to develop antibodies (Ab) to the antigens there-within. Then later, my friend, who happens to be the exact same blood type, is in a car accident and receives 2 units of my donated blood. Would they then inherit my Ab to defend themselves against yellow fever? Or does their immune system immediately kill off my antibodies? (Or does donated blood have Ab filtered out somehow and I am ignorant of the process?) If they do inherit my antibodies, is this just a temporary effect as they don't have the memory B cells to continue producing the antibodies for themselves? Or do the B cells learn and my friends is super cool and avoided the yellow fever vaccine shortage? submitted by /u/szeretlek [link] [comments]

AskScience AMA Series: IAmA restoration ecologist focused on restoring oysters to the NY Harbor in New York City. AMA! Posted: 04 Apr 2018 04:00 AM PDT Hello Reddit! I'm Dr. Liz Burmester, an ecologist with the Billion Oyster Project - a nonprofit dedicated to restoring 1 billion oysters in the NY Harbor by 2035 through education and community involvement. Why oysters? As suspension (filter) feeders and reef builders, oysters are a keystone species capable of important ecosystem services like water filtration and habitat creation for a variety of marine creatures. My research revolves around understanding how organisms survive, reproduce, and respond to stress. We use that information to inform the Billion Oyster Project's work on restoring the NY Harbor's - once impressive and thriving, but now functionally extinct - population of oysters. Before transitioning to this urbanized environment, I researched another group of keystone reef builders - corals - and their ability to recover from localized stress. As part of my work, I also serve as a mentor to high school students performing their own independent research in a career and technical education program at the Urban Assembly Harbor School in New York City. Looking forward to your questions - I'll be on at 12 ET (16 UT) - ask me anything! submitted by /u/AskScienceModerator [link] [comments]

How Did We Discover Bi-209 Is Radioactive? Posted: 03 Apr 2018 08:11 AM PDT Given that its half-life is so ridiculously long, what led us to find out that Bismuth isn't actually stable?

If the latter is the case, what prompted us to do this for bismuth? submitted by /u/Kurausukun [link] [comments]

How exactly do big, heavy snakes like boa constrictors and anacondas catch prey that is so much faster and heavier than they are?

Why did Homo sapiens become the dominant species on Earth rather than other ancient hominids?

How quickly does a SCRAM happen? Posted: 03 Apr 2018 06:55 PM PDT I don't know the situations for when a nuclear reactor needs an immediate shutdown (or how often that comes up) but I do know that once a reactor is packed up with control rods, the next step is to cool the reactor down. How quickly are control rods inserted into the reactor, and does the speed or method vary with reactor configuration? Like, are they just lowered by actuators, do they fall, do they slam down? What is the urgency of a SCRAM? submitted by /u/accidentallybrill [link] [comments]

Why do our brains wrinkle in order to make more surface area rather than fill out for volume? Posted: 04 Apr 2018 05:12 AM PDT I understand that our brains create these wrinkles to create more surface area, but why is it more important to create more surface area as opposed to volume? I would think that more volume would allow for more cells and therefore more processing power. submitted by /u/destruct4343 [link] [comments]

Why do the signs of the cofactors in a matrix alternate? Posted: 04 Apr 2018 06:55 AM PDT We learned in class today that when we're doing determinants using cofactors, the way that you determine the sign of a given term is to start with + or -, then alternate in a sort of checkerboard pattern, like + - + - + - - + - + - + + - + - + - etc. Why is that? submitted by /u/Popopopper123 [link] [comments]

Has there been a gamma frequency camera invented? If not why? Posted: 03 Apr 2018 03:28 PM PDT I know there are cameras that see in the low light spectrum, IR, and other frequencies than visible light, and I work in radiography using Geiger counters often so I'm wondering why a camera like this hasn't been made in order to keep people from needing to go into gamma radiation in order to test for it? Edit: yeah now I get why it wouldn't make a difference about having to still be in the radiation in order to receive it considering it reflects no light, but now I'm just wondering why none of you in the comments have come up with something that can, you seem like capable minds to me 😅 submitted by /u/Paydenwayne [link] [comments]

How does the Fourier Transform actually 'work'? Posted: 03 Apr 2018 03:41 PM PDT I've covered the Fourier Transform in maths so I know the formula and what it does but its coming up again as part of my chemistry course (2nd year undergrad) when used in NMR and I'm having a hard time trying to figure out how it converts from time space to frequency space. Has anyone got an explanation of how the integral 'picks out' which frequencies are present in the wave? submitted by /u/wickedel99 [link] [comments]
