| Posted: 07 Jun 2019 02:24 PM PDT After the explosion they depict an enormous light projecting from, presumably, the exposed nuclear core, it's depicted like a huge cone of light going up in the sky till the eye can see, would an exposed nuclear core in meltdown emit such a huge amount of light? Also a man is depicted looking directly into the exposed nuclear core, I presume in full meltdown, right after the explosion, immediately his face turns orange reddish and after a couple of seconds he's seriously sick and vomiting blood, is this accurate? In general this is how it is depicted all the time, as soon as people get in contact with very high dosages of radiation their skin immediately starts to look red/orange and after a while it bleeds. A firefighter that is in the middle of the rubble of the building is depicted picking up a piece of what presumably is a central part of the core, a piece of graphite, after seconds the hands from his skin looks burned, is this what would happen in such circumstances? would it be that quick? The nuclear core in full meltdown is depicted as a glowing mass on fire, is that accurate? how would it actually look? what would be the temperature of it? [link] [comments]  |
| Is the amount of energy in the universe a constant? Posted: 08 Jun 2019 05:34 AM PDT So, there is this very common knowledge that you can't create or loose energy, it is just being converted from one form to another. So...since you can't make more of it or loose it by any means...then...does that mean that since the big bang and possibly before it...the amount of energy available in the universe as a form of atoms, particles, fotons and anything else ( if there is else) that carries or has any sort of energy we can measure.....is it a constant?

| Posted: 07 Jun 2019 10:09 PM PDT There are big towers sprouting up all around me, and they're built a piece at a time. Concrete is poured and sets, then more concrete is poured for the next part and so on. Do the two different pours merge into one structure, or are they physically separate parts that are just near each other in physical space? [link] [comments]  |
| Does being born blind have any effect on learning to speak? Posted: 07 Jun 2019 08:32 PM PDT After 3 years this is my first submission anywhere, go easy on me. Watching a new Netflix movie "I am mother" ... girl being raised by a robot who has learned to speak from listening to a robot. This got me thinking if that would actually work. Obviously blind people learn to speak but I am wondering if not being able to see other's lip/tongue/mouth makes it more difficult to learn to speak. [link] [comments]  |
| What kind of hazard symbols were used in the 1950's? Posted: 08 Jun 2019 02:06 AM PDT Considering both WHMIS and Fire Diamonds were all invented after 1950 (1988 and 1960 respectively) What kind of system or symbols were used to indicate hazardous substances before that time? Need this for a project i'm working on to be historically accurate and I've tried searching everywhere but can't find anything at all, so please if anyone knows any examples I would be in your debt. Thanks for reading. [link] [comments]  |
| What would happen to the atmosphere if the oceans level raised hundreds of feet? Posted: 07 Jun 2019 12:59 PM PDT Sup science people. So, I'm writing a story - and wanting to keep it as close to scientifically accurate as I can (it's sci-fi, not realism). In the story, the sea level raises tremendously. Now, the guys in a sub right? so my first instinct was to have him notice the pressure from the barometric altimeter, and thus realize that yes, the sea has risen. BUT, is that legit? Would the pressure disperse based on the change in the sea level? Also, I'm aware that you could actually need to calibrate an altimeter for it to work right, but this story is set in the future, and I got all sorts of artistic license so I've worked around that. What really interests me is, if the ocean were to rise, what would happen to the atmosphere? [link] [comments]  |
| Why are different materials different temperature when in the same room? Posted: 07 Jun 2019 05:37 PM PDT For example: A fluffy blanket feels room temperature whilst a stainless steel benchtop feels cold? How does the stainless steel get 'colder' than room temperature? [link] [comments]  |
| Posted: 07 Jun 2019 12:24 PM PDT This might be a stupid question... but considering that you have to my knowledge an accurate accelerometer in your phone handset, surely if you give it some calibration to a speed of zero, any subsequent acceleration detected can be used to calculate a speed? Simplified case, I calibrate my phone and tell it that I'm not moving, it detects 1ms-2 acceleration for one second. I am then obviously moving at 1ms. It doesn't seem to be a thing though on phones to calculate your speed like this, as running apps track etc use GPS for that. [link] [comments]  |

| How can Antarctic ice melting cause localized sea level to fall? Posted: 07 Jun 2019 06:15 PM PDT This article appeared today - I've never seen this website before so I'm like "grain of salt" - anyway it has an interview with Harvard earth scientist Jerry Mitrovica. This bit of the article confused me: What happens with melting in Antarctica? "If the Antarctic ice sheets melt, sea level falls close to Antarctic." The article also seems to say that gravitational forces from sea ice is significant which surprised me. [link] [comments]  |
| Posted: 07 Jun 2019 09:55 PM PDT Obviously marijuana contains THC which is an endocannabinoid so it binds to receptors in the ECS. We call this being high. But you can technically get high off nutmeg. Does this also bind somewhere in the ECS? And what about peppercorn? It is psychoactive because it alleviates symptoms of THC but you do not feel high. What does it mean chemically to be high? And why don't all psychoactive substances make you feel high? [link] [comments]  |
| Posted: 07 Jun 2019 04:40 PM PDT Since totipotent cells can do everything that pluripotent and multipotent cells can do, why are pluripotent and multipotent cells formed? Why does the body not just use only totipotent cells? Unless I'm misunderstanding and totipotent must become pluripotent cells and then multipotent cells in order to develop the three germ layers, etc. [link] [comments]  |
| What is Russia's current stance on the Chernobyl disaster? (HBO series spoilers) Posted: 07 Jun 2019 12:44 PM PDT For those of us who have been watching the Chernobyl series on HBO, we've been hearing all about the USSR's misdirection and denial about the Chernobyl disaster. The show says that the USSR finally changed their stance when Legasov committed suicide, two years after the accident. What has happened since then, and what is the current stance of the Russian government in 2019? [link] [comments]  |
