Why do we have to "fall" asleep? Why can't we just decide to be asleep? |
- Why do we have to "fall" asleep? Why can't we just decide to be asleep?
- Did we prove speed of light is constant then it was incorporated in theories or did theories predict speed of light would be constant than it was proved by experiments?
- What is going on in a tree stump immediately after the tree is cut down? Does the stump continue to try to live? Is the tree instantly dead like a human would be if the human suffered something equally catastrophic?
- When classifying a moon, is it based around the relative size to the planet? Or do all moons have to be a certain size or larger?
- When the sun "bleaches" a pigment, where does it go?
- [Earth Sciences] What is the nature of underground rivers?
- What goes on in the body when someone increases their stamina?
- How do birds stay cool?
- Why does milk curdle when lemon is squeezed into it?
- How do reptiles and insects produce venom? Also if a snake is bit by one of its own will it die?
- If I were to replace the graphite anode in a Lithium Ion battery with a single layer of Graphene, would the charge time/battery life/cycle life improve?
- Is it possible that we'll find materials with a higher refractive index than diamond, or is there a reason that diamond is the limit?
- what is a steel foundry cauldron made of, why does it not melt at high temperatures?
- Why can't blood be artificially produced?
- Aside from cooling the body and exctreting harmful substances, why do we sweat?
- What happens to space debris after “burn up” occurs in Earth’s atmosphere? Where do the all those particles go?
- Do other mammalian species experience difficulties with breastfeeding?
- What is the difference between hydraulic oil and motor oil?
- Does the “keto” diet actually help burn fat faster? Or does it just come down to calorie restriction?
- How does the human body regulate its temperature?
- Would sound travel differently in heavy water as opposed to water?

| Posted: 18 Jul 2018 01:23 AM PDT Which came first? The theory or the experiment that the speed of light is always constant? [link] [comments]  |

| When the sun "bleaches" a pigment, where does it go? Posted: 18 Jul 2018 05:25 AM PDT Does some portion of the pigment evaporate? Is it a chemical change in the molecules to reflect more white light? [link] [comments]  |
| [Earth Sciences] What is the nature of underground rivers? Posted: 18 Jul 2018 05:28 AM PDT Do they kind of seep through the mud/rock/whatever is down there, or is there a sort of air gap through which they flow, like a tunnel? I'm really struggling to understand what an underground river would look like. Apparently there's one 200km wide which is 4km beneath the Amazon river, and is the same length. What is going on?!

| What goes on in the body when someone increases their stamina? Posted: 17 Jul 2018 10:17 PM PDT What increases stamina? Scientifically speaking, what is stamina? [link] [comments]  |
| Posted: 18 Jul 2018 05:41 AM PDT If they're warm-blooded but don't have sweat glands, how do they regulate their body temperature in 90+ degree weather? [link] [comments]  |
| Why does milk curdle when lemon is squeezed into it? Posted: 18 Jul 2018 05:16 AM PDT |

| Why can't blood be artificially produced? Posted: 17 Jul 2018 03:11 PM PDT |

| Posted: 17 Jul 2018 06:12 PM PDT Not sure if this falls under the realm of physics, astronomy, or earth sciences but yeah, what becomes space debris post burn up? Does it all fall back to earth as tiny chunks? Does it become a cloud of small particles? What really happens to space debris when "burn up" occurs? [link] [comments]  |
| Do other mammalian species experience difficulties with breastfeeding? Posted: 17 Jul 2018 05:28 PM PDT So many human women have trouble breastfeeding their newborns (latching problems, milk supply problems, etc). Is this issue unique to humanity, or do whales, dogs, and raccoons have these problems too? If it's a human-specific problem, why? [link] [comments]  |
| What is the difference between hydraulic oil and motor oil? Posted: 18 Jul 2018 02:38 AM PDT |
| Posted: 17 Jul 2018 06:35 PM PDT Does the "keto" diet actually help burn fat faster? Or does it just come down to calorie restriction? People at work were saying it burns fat instead of carbs, but I told them it's calories in vs out at the end of the day. Edit. And does it burn stored fat or consumed fat? [link] [comments]  |
| How does the human body regulate its temperature? Posted: 17 Jul 2018 12:49 PM PDT The ideal temperature is the one the enzymes work at their optimum, yet how does the body "know" how to keep that temperature? [link] [comments]  |
