| Solar sails and how they work? Posted: 27 Jul 2018 11:10 PM PDT When people talk about light there is spoken of a massless thing. ( as far i understand) I know that light is a wave aswell as a partical But when the talk about a solarsail they use light to (push) a spacecraft using light? So then doesnt light need to have atleast some mass to (push) an object like a solarsail ? Cause if there is no mass than how does the solar sail works? Tried to look it up but could not find a decent anwser EDIT: if asked before in this sub links are welcome [link] [comments]  |
| Why doesn't carbon monoxide turn into carbon dioxide when additional oxygen becomes present? Posted: 27 Jul 2018 09:59 PM PDT Or does it? It seems to me that when CO comes out of the tailpipe of a car that it would immediately turn into CO2. If it doesn't do this, why? If it does, why does leaving a car running in your garage kill you so fast? Is it just using up all the oxygen faster than it can be replenished from outside the garage? [link] [comments]  |

| Lighting a lighter in pure oxygen? Posted: 28 Jul 2018 03:08 AM PDT In the murders of midsomer ep 4, the lions of Causton, at the very end there is a man in a hyperbaric chamber, you can see a monitor reading 100% oxygen. He takes out a lighter made out of metal and lights it while locked in the room. The room explodes, the explotion blasts through at least 2 doors, travels like 30 meters to blow up a bunch of windows and come out as a huge fireball. I do not think that is what would have happend at all. There was nothing near the lighter exept for his hand. Would it explode at all? If not what would happen? (sorry if my english is bad) [link] [comments]  |
| Why is the pollen count higher in London than the North of England? Posted: 28 Jul 2018 06:38 AM PDT Why is the pollen count higher in London than elsewhere in the UK? Is it due to more male (dioecious) trees planted in recent years in the city to absorb more pollution? Or why? Help as sister out please. [link] [comments]  |
| Posted: 27 Jul 2018 05:32 PM PDT I know that things like pH and osmosis can really fuck things up for a saltwater-dwelling creature, but i'm just curious if there are any exceptions. [link] [comments]  |

| Why do quasars expell beams of energy from their poles? Posted: 27 Jul 2018 10:00 AM PDT Not really sure if its supposed to be a particle beam or electro magnetic energy beam, but still why does this occur? If you have no dang idea on what I'm talking about, here is a pic: https://geek.hr/znanost/wp-content/uploads/sites/14/2014/06/09848848094.jpg [link] [comments]  |
| Which factors cause hyperfocus or a state of flow (for example in Asperger syndrome)? Posted: 28 Jul 2018 12:30 AM PDT Which brain regions, neurotransmitters, and other factors induce a state of flow or hyperfocus? [link] [comments]  |
| I don't even know where else to begin searching for an answer, so - what are these things? Posted: 27 Jul 2018 01:40 PM PDT Honestly, this question has ate away at me my entire life, but whenever I see one of these things, almost like a star-shaped spec of fluff, I can't help but wonder what they are. Here's the image: https://imgur.com/a/W7c2aYr [link] [comments]  |
| What causes jalapeño peppers to change color when pickled? Posted: 27 Jul 2018 06:03 PM PDT I recently started pickling hot peppers and last week this question came to mind. Is the vinegar in the brine affecting the pigment? What's going on at a molecular level? [link] [comments]  |
| Does food spinning in the microwave actually make a difference in the way it is heated? Posted: 27 Jul 2018 11:43 AM PDT I remember when I was younger, microwaves didn't have spinning plates. Now they all do. Does it make a difference? [link] [comments]  |
| Posted: 27 Jul 2018 08:26 AM PDT Since (to my knowledge), there are 8 color states that any given quark can be in, are these states ever fixed in place, or rather, definitive, or is each of the three quarks making up any given proton always in a superposition of these color-states due to interactions with the gluon field? Assuming they are always in superposition, is there any way we could destroy that coherence to create a definite triplet of color-states, and if so, would any specific configuration cause observable differences in that proton's outward behaviour? i.e. Would protons compromised of quarks which differed only in color act the same?

| Is there a simple explanation for why autorotation occurs? Posted: 27 Jul 2018 06:28 AM PDT I don't really understand how autorotation can create lift by seemingly spinning the rotor. I understand air goes up through the rotor, but why does it make the rotor spin and how does it generate lift without forward propulsion? Thank you! [link] [comments]  |
| Is it possible for mosquitos or flies to get concussion? Posted: 27 Jul 2018 02:15 AM PDT If we hit them and they hit the wall very hard, would they get brain* concussion? [link] [comments]  |
| Can you count algae in a non-pure culture with a hemocytometer? Posted: 27 Jul 2018 07:34 AM PDT I would like to get a quantitative count of algae in an IBC tote full of nutrient rich water(used for hydroponics). We've noticed biofilm in the tank and would like to get a baseline algal count before we start treating it. I've used a hemocytometer to count algae before but only in pure cultures. I was just wondering if it would work in a non-pure culture. Thanks! [link] [comments]  |
