- Can a literal bad apple actually spoil a barrel of good apples?
- How do sharks smell blood 0.4km away? Does a particle of blood travel to their nose through the water?
- If I was floating in the vacuum of space and I threw a credit card or a rock by me, would it orbit around me like a moon?
- How many derivatives are there?
- Could there be a branch of theoretical chemistry in 4 dimensions? (So chiralitically opposed substances are the same)?
- Is chirality an issue in synthetic chemicals meant for human consumption?
- What scientific project currently in operation or in development is most likely to discover complex on another planet?
- What is the maximum mass/size a Star can reach?
- What percentage of the sun's power gets to Earth?
- Prompted by the question about stars on the front page today, I'm wondering, is it possible for there to be a solar system with only planets? I.e., all planets in the system orbit around a much larger planet at the center?
- Are some forgotten memories forgotten forever?
- Can a dying star extend its life-span by absorbing another star?
- Can we have a mental limit of comprehending things just like we have a physical limit to which we can push our bodies to?
- What creates new cells after old cells undergo Apoptosis?
- Would early humans have had to cut their hair?
- Will a black-painted surface cool faster or slower at night compared to a white surface?
- How on earth did they start using laser eye surgery?
- Why is some ice cloudy and some ice clear, including the ice you make at home?
- Why was hydrogen concentrated in the centre of our Solar System during its creation? Wouldn't it escape the rotating accretion disc as it escapes Earth's atmosphere due to its rotation?
- where did the hellenic languages go ?
- When you say that the movement of the light source doesn't affect the light's speed, does that mean it is actually impossible the reduce/increase it or it means "the difference is too small to bother"?
- Do we have any pictures of the sun from different planets?
- What makes us build up a tolerance to substances like alcohol, and what makes lowers it when we stop consuming?
| Can a literal bad apple actually spoil a barrel of good apples? Posted: 20 Mar 2016 03:09 PM PDT I know the saying of how all it takes is one bad apple, but is that actually true? Can a rotten apple ruin a barrel of good apples? [link] [comments]  |
| Posted: 20 Mar 2016 07:49 PM PDT Or is it a misconception that to smell something means that a particle from the source of the smell needs to have entered your olfactory system? [link] [comments]  |

| How many derivatives are there? Posted: 21 Mar 2016 04:56 AM PDT Say we start with an object, and its position. The derivative of that would be the rate of change of its position, or its velocity. The derivative of that would be acceleration. This is where most high school physics classes stop. But I'm sure that it is near impossible to go from no force applied to an object, to say 10lbs of force instantly. So there must be a derivative of acceleration. How far back will this go before the derivative is equal to 0? [link] [comments]  |
| Posted: 21 Mar 2016 02:08 AM PDT As the title suggests, or would it simply mean that some compounds or mixes of compounds couldn't exist? Please pardon my poor terminology. [link] [comments]  |
| Is chirality an issue in synthetic chemicals meant for human consumption? Posted: 20 Mar 2016 06:17 PM PDT I'm wondering, as the title says, if chirality matters for synthetic chemicals. Or at all, I guess. [link] [comments]  |

| What is the maximum mass/size a Star can reach? Posted: 21 Mar 2016 05:56 AM PDT If there is no limit to the answer of this question, how can stars have a limit on the amount of light they produce but not the mass they can be made of? Would this mean a smaller Star can produce more light than a bigger one at the peak of their light emitting life? [link] [comments]  |
| What percentage of the sun's power gets to Earth? Posted: 20 Mar 2016 03:51 PM PDT I understand that much of it isn't absorbed. That may affect the answer to my second question. How many Earths could be potentially supported by our star if all energy was used? Question came up in my mind by thinking of the possible power from a Dyson Sphere. [link] [comments]  |

| Are some forgotten memories forgotten forever? Posted: 21 Mar 2016 04:55 AM PDT I was wondering about this, we make memories all the time. But we fail to remember quite a bit of them. Most of them in fact, I think. So, are some of those memories lost forever? Or can they all be recovered given the proper method or tools? How about memories of a young child? [link] [comments]  |
| Can a dying star extend its life-span by absorbing another star? Posted: 21 Mar 2016 03:01 AM PDT Can a white dwarf star absorb another star to either extend its life as a white dwarf, or regenerate back to a red/yellow/blue star? Can a neutron star do the same? Or would the particles simply break down to neutrons? Would red giants shrink after absorbing a blue star, due to the new supply of hydrogen? Would they change color at all? [link] [comments]  |
| Posted: 20 Mar 2016 11:12 AM PDT I mean is there a point where there is no more knowledge to be ascertained because we are mentally incapable to understand it? [link] [comments]  |
| What creates new cells after old cells undergo Apoptosis? Posted: 21 Mar 2016 02:24 AM PDT I understand the process of the destruction of a cell (in relation to sunburn), just not what happens after the cells destruction. Thanks x [link] [comments]  |
| Would early humans have had to cut their hair? Posted: 20 Mar 2016 12:11 PM PDT In modern day, human hair is capable of getting ridiculously long. However, if you look at animals, most have fur that doesn't grow beyond a certain length. Would early humans and/or Neanderthals shared this trait, or would their hair be capable of growing as long as ours? Setting aside the social significance of haircuts, it doesn't seem particularly convenient to be running around with huge masses of hair. [link] [comments]  |
| Will a black-painted surface cool faster or slower at night compared to a white surface? Posted: 20 Mar 2016 07:53 PM PDT I know sunlight is better absorbed by black surfaces, and they warm up faster and hotter in the daytime. But what effect (if any) would color have on nighttime cooling? [link] [comments]  |
| How on earth did they start using laser eye surgery? Posted: 20 Mar 2016 11:14 PM PDT They cut your eye open and shoot lasers at it; how did they get to the stage of being so confident it worked that they were willing to attempt something so dangerous on a real person for the first time, all whilst not being able to test it for real?

| Why is some ice cloudy and some ice clear, including the ice you make at home? Posted: 20 Mar 2016 01:08 PM PDT |
| Posted: 21 Mar 2016 05:06 AM PDT An additional question: What caused the gas giants to form further away from the centre? [link] [comments]  |
| where did the hellenic languages go ? Posted: 21 Mar 2016 04:36 AM PDT title, greece is the only variation left my guess is that it dissapeard when the turks came rolling in with the mongols in what is now turkey. i got the theory from looking at this map where you can see that in turkey they dont speak an indo-european language but they do in india [link] [comments]  |

| Do we have any pictures of the sun from different planets? Posted: 20 Mar 2016 08:26 PM PDT I have tried looking all over the web but can not find any real pictures, only artist impressions. [link] [comments]  |
