- How do I know the exact pace to stay on a treadmill?
- Does a massive star have an event horizon underneath it's surface, centered around its centre of mass?
- Why do we have opioid receptors, nicotonic receptors, cannabinoid receptors, etc? These phrasings imply that our brains are almost meant to accept these molecules. How right or wrong is that, or do we even know?
- Why can't we get to Mars easier by placing intermittent satellites (space stations) along the way?
- Do we need to invent a new math, like Newton did with Calculus, to unite Quantum Mechanics and General Relativity?
- What is/are the molecular structure(s) that allow histamine to bind to its 4 receptors?
- are there any known cases where a molecular orbital ISN'T a linear combination of the atomic orbitals?
- Why can we erase but not scratch off pencil writings? Why do some erasers work better than others?
- How important is the shape of the first car in a train for its efficiency?
- Lets say there's a 1/1000 chance of a coin landing on its side when you flip it. How many times would i need to flip the coin for there to be a 50% chance of it landing on it's side?
- If scientists does not know what is causing Multiple Sclerosis. How do they produce laboratory rats for testing new drugs?
- On a microscopic level, what makes something feel soft?
- Do certain regions of the brain increase in temperature, even by a minute amount, with increased activity?
- Bird Migration Distances: How does the Red Knot travel 14,000km while only stopping once at the Delaware Bay?
- What actually causes a sore throat? Why do throats become inflamed/infected/etc. as opposed to, say, the roof of the mouth, or under the tongue?
- If the cells of an embryo duplicate once every 20 mins, how do the cells know when to stop growing at that pace and why is the gestation period so long if this happens?
- Why do some gases behave more ideally than other gases?
- If you are making and destroying brain cells all the time how do remember your memories?
| Is it possible to calculate nth digit of pi for any n in a limited amount of memory? Posted: 11 Oct 2016 05:26 AM PDT Say, my algorithm can only use 1MB of memory. Is there a limit to how far can I calculate pi, assuming that I only need one digit and don't care about all the previous digits of pi? [link] [comments]  |
| How do we know what earth's layers are (crust, mantle, outer core, inner core)? Posted: 10 Oct 2016 05:59 PM PDT Was watching a SciShow Kids episode (flipping fantastic YouTube channel) about the earth's layers. It dawned on me though that I don't think I've ever heard how we came up with the layers. Knowing we can't get very deep (relatively speaking), I presume it must be based on some other science experiments performed? [link] [comments]  |
| Would it ever be possible to have a low latency data-connection between Earth and Mars? Posted: 10 Oct 2016 08:48 PM PDT I understand that conventional technologies for communication are limited by the speed of light but are there any theories of possible ways to create a connection with similar latencies to those found on Earth? What engineering and scientific advances would need to be made for it be possible? [link] [comments]  |
| Why do train tracks rest on a bed of gravel/pebbles? Posted: 11 Oct 2016 05:53 AM PDT For someone completely uninformed, this seems inherently unstable, but it can't be since it's been the standard for so long. Does anyone know what makes this the best way to place tracks? [link] [comments]  |
| How do I know the exact pace to stay on a treadmill? Posted: 10 Oct 2016 08:02 PM PDT I've started running seriously recently and it felt kind of unnatural that I knew the exact speed to run at to stay at the same spot in a treadmill. Is this a learned action? Or can anyone just get on a treadmill and run? [link] [comments]  |
| Posted: 11 Oct 2016 03:26 AM PDT Basically, If the star was transparent, would we see a black hole within it before it dies? Since the two both have the same mass. [link] [comments]  |

| Why can't we get to Mars easier by placing intermittent satellites (space stations) along the way? Posted: 10 Oct 2016 11:26 PM PDT If planets can orbit the Sun, then surely man-made space stations could be placed into orbits to mimic planets. We could place many of these into orbits between Earth and Mars. Then shuttle things back and forth between the shorter distances. [link] [comments]  |

| What is/are the molecular structure(s) that allow histamine to bind to its 4 receptors? Posted: 11 Oct 2016 12:03 AM PDT I've been doing some basic research into the subject. I know that histamine is comprised of an aliphatic amino group and an imidazole ring (or at least I think it is). What part of the histamine receptor and histamine are binding? A diagram would be especially helpful, but not necessary. [link] [comments]  |

| How important is the shape of the first car in a train for its efficiency? Posted: 11 Oct 2016 05:53 AM PDT Would a train that strapped a large bowl to its front be noticeably impacted by the reduced aerodynamics, or would the difference be negligible compared to the resistance of the rest of the train?

| Posted: 10 Oct 2016 03:48 PM PDT Also what would be the chances of it landing on it's side if i flipped it 1000 times? [link] [comments]  |

| Posted: 10 Oct 2016 11:58 PM PDT Does in an increase in brain activity result in a measurable uptick in local temperature? [link] [comments]  |
| Posted: 10 Oct 2016 01:31 PM PDT How often do birds with long migration distances sleep, eat, rest? [link] [comments]  |
| Posted: 10 Oct 2016 08:14 AM PDT I've been trying to find any information on the specific physiology behind a sore throat, but everywhere I look there's just information on the pathogens that cause sore throat. I'd like to know what's going on down to the cellular level, and why it seems to affect the throat in particular. [link] [comments]  |
