- Why is radioactive decay a random process? Subsequently, why isn't “random” a euphemism for “we don't understand the cause yet”?
- If no one took flu shot in US, would flu spread rapidly? Or do we have some immunity from first exposure that doesn't wane away?
- What is happening to your brain when you come round from anaesthesia? Those videos seem like it’s the most childlike high of any drug.
- Is there a boundary between elements that must exist and those that cant? I.e. what happens if you keep adding protons?
- Is it possible to predict if a reaction is exothermic/endothermic based on the relative stability/energy of the reactant and product?
- Is there a correlation between the reduced pollution from Quarintine/Covid-19 restrictions and the snow in some European countries like Spain? How relevant is this to long term global climate change plans?

| What determines the shape of a nebula? Posted: 09 Jan 2021 07:33 PM PST My question is what conditions impact how nebulas form and why they seem to have unique shapes. [link] [comments]  |
| Why do lasers have a "grainy texture" on the light that they produce? Posted: 09 Jan 2021 11:36 PM PST I was shining a laser on the ceiling and the reflections that came down seemed to have a somewhat grainy quality about them, and I'm not sure why. Is it the material that it is reflecting off of, is it the fact that me holding it isn't stable enough to keep the light consistent, or is that a property of laser beams? Thanks! [link] [comments]  |

| Posted: 09 Jan 2021 02:56 PM PST i.e If an alcohol is halogenated into a alkyl halide, would it be exothermic or endothermic? (Assuming there's no supporting data) Since the C-Cl bond is weaker than the C-OH bond, I imagine it would be exothermic but I'm not sure if this is the correct reason why or not. But since -Cl is a better leaving group than -OH, which itself needs to be protonated to -OH2+ to leave C, wouldn't the alcohol be at a lower energy level than the alkyl halide, making it endothermic? Sorry if my wording is confusing, it's been a while since I covered this topic lol [link] [comments]  |

| Posted: 09 Jan 2021 12:40 PM PST I suppose to be more specific there are two types of scenarios with an answer like this (that I can think of): The effect of a vaccine reducing the spread of the virus gradually, or is there specific points along that distribution process that would hamper the virus?

| Posted: 09 Jan 2021 03:59 PM PST For example, let's say you have a heat source you want to insulate and you have a layer of aluminum and a layer of cotton. Does it matter which layer you put first or will the result be the same? [link] [comments]  |
| What is the smallest ground bird? Posted: 09 Jan 2021 09:13 PM PST The smallest terrestrial non flying bird is the inaccessible island rail. How about the smallest ground bird that can fly? [link] [comments]  |
| How can scientists tell when mass extinction events happened? Posted: 09 Jan 2021 04:51 PM PST So I'm trying to understand history and science a little bit more, but I definitely know very little as of right now. I've been reading about extinction events, specifically The Big 5, but I can't find an explanation of how scientists know these events happened. Is it just that there are far fewer fossils dating back to these time periods, or is it something much more complex? Thanks! [link] [comments]  |

| How do topical creams affect bacteria etc below the skin after they've dried? Posted: 09 Jan 2021 12:01 PM PST I read about a chemical in anti-acne cream I use, Benzoyl peroxide, and that it primarily works by killing bacteria under the skin, but I have to ask how does this work after its dried onto my skin? Is it because the skin absorbs a certain amount as it dries? If that's the case, why does it keep working after the ointment has dried, but stops if I remove said dried piece of ointment?

| Why do some seconds seem to tick faster? Posted: 09 Jan 2021 11:28 AM PST So I've noticed when I'm running on the treadmil and looking at the time on my digital timer the seconds sometimes jump from 19 to 21 for example, as if my brain doesn't process 20 or goes really really quickly. Is this due to any mechanism of the human eye? [link] [comments]  |
| Posted: 09 Jan 2021 06:21 AM PST As this is not my field and reading the appropriate studies is quite complex, this has been bothering me, is this idea scientifically proven or just speculation and or politics? [link] [comments]  |
