- The Saturn V Rocket is called the most powerful engine in history, with 7.6 million pounds of thrust. How can this number be converted into, say, horsepower or megawatts? What can we compare the power of the rocket to?
- What actually causes Scintillating Scotomas, and why do only some people suffer with them?
- Are there non-negligible losses to the earth's ecosystem when harvesting energy from natural processes?
- Is it possible (or are we able) to isolate cytosol from a cell or group of cells?
- Has there been any observed (repeated preferred) differences in patterns of behaviors of (any) sea creatures before, during, or after tropical weather?
- Is there a link between mythological constructions and prehistorical interactions between homo sapiens and extinct species (other homo species or extinct megafauna)?
- How could math change in the next 100 years?
- Does NASA (or another group) have an official first contact protocol?
- Is it possible that there are repulsive forces that only operate at very large distances?
- How does a polymer such as nylon behave when placed in boiling water?
- Can patients diagnosed with serious psychopathologies (i.e. schyzophrenia) lose their pathological traits after a brain trauma, coma or amnesia?
- Are there any biocompatible polymers that degrade at a slightly basic pH (around 8 or 9) but do not degrade at physiological pH (7.4) ?
- How many structural isomers exist for an alkane with N carbon atoms?
- Are there any animals who see heat radiation?
| Posted: 02 Sep 2016 05:00 AM PDT Dr. Carin Bondar is the author of Wild Sex: The Science Behind Mating in the Animal Kingdom, just published Pegasus Books. She received a PhD in population ecology from the University of British Columbia and has since hosted a variety of online and television programs, working with Scientific American, National Geographic Wild and the Science Channel. She is currently the lead presenter on Discovery World's "Brave New World with Stephen Hawking"and a featured presenter on all four seasons of "Outrageous Acts of Science" (Discovery, Science Channel). Her independent web series "Wild Sex" has engaged over 55 million viewers and was the subject of a presentation given at TED Global in Edinburgh in 2013 which received over 2.3 million views. She lives in British Columbia, Canada. I'll be on around 4 PM EDT (21 UT), ask me anything! [link] [comments]  |

| Posted: 01 Sep 2016 11:33 PM PDT Earlier I asked this question in response to a Futurology post about Iowa's recent commitment to 100% renewable energy, and thought I'd re-phrase it for /r/askscience since there seemed to be some interest: [notice: this is a speculative question only] Given the processes of "harvesting" energy from "renewable" sources (such as wind, hydro-electric, solar, geo-thermal, tidal, etc) involves collecting mechanical or chemical potential energy their respective systems, do the amounts of potential energy we currently or could possibly harvest from them have a negligible impact on their respective systems? In other words; does the mass harvesting of wind energy effect global weather patterns? does it effect local weather patterns? Does it slow the travel of ground level air enough to have a measurable impact? Does the collection of tidal energy slow the slop of the ocean enough to effect tides? Does the collection of solar on a large scale actually cool the planet by collecting and reflecting solar energy before it has an opportunity to heat up the environment? I apologize ahead of time if the questions I ask have already been answered and disputed, or are completely irrelevant given the available energy options we have. I am not an environmental science and dont understand the numbers, however I do know enough physics to understand that the energy must come from somewhere (mechanical, chemical) and means a net loss from the harvested system, never-mind the losses in transferring energy from one state to another.

| Posted: 01 Sep 2016 08:38 PM PDT To give an example, creatures akin to ogres and trolls exist in the same geographic areas as Neanderthals and other homo species. Could our mythologies and stories about trolls and ogres actually be a collective sociological memory of our species? Is there any theories akin to this or is this just silly? [link] [comments]  |
| How could math change in the next 100 years? Posted: 01 Sep 2016 01:06 PM PDT What new things might we discover in math? Could we start to use a different logarithm to everything that makes everything easier? [link] [comments]  |
| Does NASA (or another group) have an official first contact protocol? Posted: 01 Sep 2016 06:58 PM PDT If there is such a thing then does it have a tiered response for the type of contact? Something like "If a radio signal was received do X", "If a verified observation occurs do Y, etc. [link] [comments]  |
| Is it possible that there are repulsive forces that only operate at very large distances? Posted: 01 Sep 2016 05:42 PM PDT I know there are forces that only become noticeable at very short distances. Is it possible that there are forces that are only noticeable at very large distances that could counteract gravity and account for the expansion of the universe? [link] [comments]  |
| How does a polymer such as nylon behave when placed in boiling water? Posted: 02 Sep 2016 03:23 AM PDT When it comes to alkalines, it's generally known that most of them have very low heat resistance, with melting points around 200 degrees C. Water boils at around 100 degrees C, so in theory there should be no structural damage to a piece of nylon fiber, right? That is, there wont be an excessive amount of nylon strands left in the water after the nylon piece is removed. I am asking this because my mother is very sceptical to the usage of plastic in direct contact with food / drink, especially when there is heating involved. A good example would be tea stored in teabags made out of nylon-like material instead of paper. Also as a bonus question: What kind of effects would the consumption of plastic have on the human body?

| How many structural isomers exist for an alkane with N carbon atoms? Posted: 01 Sep 2016 08:27 PM PDT Does such a formula exist? What if we consider optical isomers for higher-order alkanes? [link] [comments]  |
| Are there any animals who see heat radiation? Posted: 01 Sep 2016 04:17 PM PDT Given heatwaves, just as light, are e/m-radiation (infra-red) it's surprising humans cannot see them. It's a great perk both for the prey and for the hunters. You can see the lion hiding in the bush and can sense which of the holes in the ground are inhabited and which are not. And yet human hunters (including army and police) have to rely on special cameras to extend their visible spectrum. Has their sight been nerfed along with their smell, fur and fangs because they were too op or is it a hardcoded cap in the spectrum, i.e. not a thing with any other animal as well?
