| Why didn't the Ohio earthquake this morning not create a tsunami-like wave? Posted: 10 Jun 2019 11:18 AM PDT Did the earthquake in Ohio this morning produce any kind of wave resembling a tsunami? My guess is that the distance to the other coast wasn't far enough to allow a wave to gain momentum, but I would assume that there would be something generated. [link] [comments]  |

| How do space telescopes deal with vibration during launches? Posted: 10 Jun 2019 10:45 PM PDT Given that their whole optics have to align very precisely to the spec, how do engineers build space telescopes to be able to withstand vibration during launch? Just a lot of structural support? Also the insane deployment process of the JWST really worries me. There seems to be like a millions moving parts involved. Do engineers have to use any additional measures for the JWST compared to relatively basic traditional tube-and-mirrors telescopes? [link] [comments]  |
| Posted: 11 Jun 2019 01:47 AM PDT I came across this excellent map of asteroids on r/dataisbeautiful (said map / data-viz) and it had me thinking if we were to settle the solar system where is the living space actually at. Is most of the space you could build bases on or so on asteroid rocks or on planets? Seems the first point of departure for answering that is to find out the relative mass and area of stuff around sol, hence the questions. [link] [comments]  |
| Difference between citrus, rutaceae, and hesperidium? Posted: 10 Jun 2019 11:37 PM PDT Plant taxonomy is a lot less popular a topic on google than animal, so it's hard for me to find an answer. I know grapefruit, lime, orange, etc. are all citrus fruits (genus citrus) and also belong to the order hesperidium. But the two words (citrus and hesperidium) seem to be interchangeable. And what of citrus fruits' family Rutaceae? Are there any Hesperidium that are not Rutaceae, and any Rutaceae that aren't Citrus? This is confusing to me. [link] [comments]  |
| Why do boiled eggs smell but scrambled eggs don't? Posted: 10 Jun 2019 08:48 PM PDT This question was posed by a friend and I don't know the answer. She's curious about the smell when you finish cooking eggs by the different methods. I think she may not be able to smell scrambled eggs because of how often she eats them. Please correct me!

| Posted: 10 Jun 2019 08:40 PM PDT From what I know, the flush-deck design for WWI-era destroyers was due to the findings it offered greater hull strength than if the deck was broken into different levels. According to Wikipedia though, the newer interwar periods saw destroyers receive raised forecastles because a flush deck meant that the bow tended to be very wet, without addressing any of the pros and cons and whether or not there was any additional things to consider in the decision to switch the design, my first question. That leads me to believe that perhaps the newer generation of destroyers somehow figured out how to retain greater hull strength, but I could not find anything to address this, and thus can't verify my hypothesis, hence my second question. The interesting thing I find is that the bigger battleships and cruisers retained a flush deck even for those built during the interwar period and WWII itself. Another interesting thing I find is that modern warship designs seem a flush-deck design due to the necessity for helicopter facilities and massive superstructures, possibly to house expensive and heavy equipment such as radars, though this is just my hypothesis.

| How are plumbing and drains designed for a mountain? Posted: 10 Jun 2019 09:33 PM PDT On vacation in a cabin on a big mountain in the Smokies. Curious how they get water pressure to be available and reasonably constant for structures located at all different heights on the same mountain. Bonus: If the soil is full of boulders, I assume septic systems are out? [link] [comments]  |
| Why do radioactive elements still exist? Posted: 10 Jun 2019 07:02 PM PDT if for example something like francium-223 which has a half-life of 22 minutes how do we even know it exists if the earth been around for many millions of years even before life was on it so how do stuff with short half lives even exist. Can the earth create elements?? [link] [comments]  |
| What effect does the moon's gravitational pull have on dry land (as compared to the tide for water)? Posted: 11 Jun 2019 03:21 AM PDT Is there any measurable or significant effect on dry land like the rides? I read an article about that moon of Jupiter that is stretched and compressed so intensely that its surface pops like a zit I was just wondering what it would be like for there to be a moon but no oceans, what effect would there be if any at all?

| How long does the criticality reaction last in a nuclear weapon? Posted: 10 Jun 2019 05:02 PM PDT The energy of a nuclear weapon is released in the critical chain reaction of whatever fissile material is in it. From the first nucleus fissioning to the last nucleus fissioning how long is the reaction? Similarly for hydrogen bombs how long is the hydrogen fusion chain reaction? Do they last milliseconds or is it longer? [link] [comments]  |
| Posted: 10 Jun 2019 08:21 PM PDT Had a showerthought. Places like the US produce a bunch of CO2 gases that make up the ozone layer (I think, I'm no scientist). So when that gas reaches the ozone layer, does it spread evenly in the atmosphere or is it denser above the US and other gas-producing countries. If so, is it thinner above countries that don't produce so much gases? Hope that's the right flair. [link] [comments]  |

| Altitude Sickness? How sudden can it take effect, what can happen? Posted: 10 Jun 2019 02:05 PM PDT Hello again scientists! So, my latest question is pretty simple. Altitude sickness, how long does it take to have an effect? I'm finding online that it usually takes between 12-24 hours for somebody to feel ill due to a raise of over 8000 feet. Well, what if somebody were suddenly exposed to such an altitude!? What if, for instance, some massive giant were to scoop you up from the ground and raise you, miles above the surface and right up to his own face? Any info, random tangents, strange possibilities etc are more than welcome, thanks for takin' a look! [link] [comments]  |
