- When sign language users are medically confused, have dementia, or have mental illnesses, is sign language communication affected in a similar way speech can be? I’m wondering about things like “word salad” or “clanging”.
- When an avocado is not ripe, are the fats and nutritional content just as present or does the ripening process make them available? If so, why?
- Does the ISS need to constantly make micro course corrections to compensate for the crew's activity in cabin to stay in orbit?
- How do ants breakdown/eat larger insects? Do they eat them on the spot or do they take pieces back to the nest. How does it work?
- Is the orbit of Earth around the sun affected by any of the other planets in our solar system? If so, how?
- Are there any buildings large enough to be affected by the curvature of the earth? How large would a building of this size be? Also, what engineering methods are used to counteract this?
- Why does freezing something make it more “fragile”?
- Why are vaccines for things like Ebola are so hard to make?
- What causes the pitch of a sound? Why doesn't the pitch change when it is outside of its tube/voicebox?
- Does the curvature of a wineglass affect the frequency?
- There are many functions that cannot be integrated, ie non elementary integrals. Are there any functions with non elementary derivatives?
- Can you measure a particle's position then measure it again after a finite amount of time and find it a distance farther than it could go if it was going the speed of light?
- What exactly was the Debian OpenSSL bug?
- What are we reallly seeing in this gif of a pulsar?
- Why it is possible to see the interior of a microwave?
- Why do groups alpacas defecate in a communal dung pile?
- I've been taught that hydrostatic pressure is calculated with the fromula p = ρgh regardless of the shape of the liquid above. I've seen the proof for it but I still can't get my head around it. Does hydrostatic pressure really work the way the formula says it does?
- What vector space does the elements of gauge groups act on?
- Why does turbulent flow cause more erosion than laminar flow?
| Posted: 02 Sep 2018 05:00 PM PDT Additionally, in hearing people, things like a stroke can effect your ability to communicate ie is there a difference in manifestation of Broca's or Wernicke's aphasia. Is this phenomenon even observed in people who speak with sign language? Follow up: what is the sign language version of muttering under one's breath? Do sign language users "talk to themselves" with their hands? [link] [comments]  |
| Posted: 02 Sep 2018 07:11 AM PDT Here I am sitting with a bag full of avocados, and all of them are not quite ripe yet. I wonder if the fat and nutritional content are the same at this stage as when it ripens or if there is a type of transformation that happens as it ripens. If, so, why? [link] [comments]  |
| Posted: 03 Sep 2018 06:56 AM PDT I know the crew can't make the ISS plummet to earth by bouncing around, but do they affect its trajectory enough with their day to day business that the station has to account for their movements? [link] [comments]  |

| Why are vaccines for things like Ebola are so hard to make? Posted: 02 Sep 2018 03:55 PM PDT So my understanding is that vaccines are made from weakend or dead forms of the bacteria or virus responsible for the disease. Why is it so difficult then for vaccines to be made for diseases like Ebola or HIV? What's different about those diseases? [link] [comments]  |

| Does the curvature of a wineglass affect the frequency? Posted: 02 Sep 2018 07:06 PM PDT I am currently writing a report on the 'Singing Glass' experiment. I am measuring the frequency of the noise heard when rubbing your rim around a wineglass using a chromatic tuner while varying the type of wineglass used and the volume of liquid in each wineglass. Would the curvature of the glass have any affect on the frequency resonated? [link] [comments]  |

| Posted: 02 Sep 2018 03:03 PM PDT When you measure the position of a particle the wavefunction collapses to the eigenstate of that position in that system. Then it evolves overtime. What is the mechanism of what happens after you measure the particles position that would make it so that it has 0 probability to be found farther than it could go at the speed of light? Is this not a real problem because of how relativistic quantum mechanics works? I was hoping someone would be able to explain the math of how this remains impossible. [link] [comments]  |
| What exactly was the Debian OpenSSL bug? Posted: 02 Sep 2018 07:36 PM PDT There was a famous bug, where in 2008, the Debian maintainers for OpenSSL decided to "fix" a bug where Valgrind was complaining that OpenSSL was copying from an uninitialized buffer. So the maintainer commented out the code, resulting in significantly worse randomness. But what was OpenSSL doing? Isn't that (assuming that uninitialized variables have old data and aren't 0) undefined behavior, which any compiler could have done behind everyone's back? What was OpenSSL thinking?

| What are we reallly seeing in this gif of a pulsar? Posted: 02 Sep 2018 07:41 PM PDT Hello AskScience, I am making a video game and am trying to visualize some galactic phenomenon and am currently looking at trying to recreate pulsars with particle effects. I found this gif and it looks to me that this is two toruses and a jet. It is hard to tell from this, and I was hoping someone might be able to help clarify what we are really seeing here. https://media.giphy.com/media/6Iy2GdjElvPUc/giphy.gif Here is a 3D render of what it looks like to me, but not sure if there are optical effects or I am interepreting this correctly. Any help is appreciated! [link] [comments]  |
| Why it is possible to see the interior of a microwave? Posted: 02 Sep 2018 01:47 PM PDT As far as my physics and microwave knowledge goes, this machine heats up food using electromagnetic waves, and it uses a Faraday cage to avoid those waves from getting out. But, as light is an electromagnetic wave as well, why those can go through the microwaves's window allowing you to see what's inside, instead of getting blocked? [link] [comments]  |

| Posted: 02 Sep 2018 03:44 AM PDT To explain my confusion, here's a setting that's troubling me: Let's say that there is a pool whose depth is 1 meter. A scuba diver climbs to that pool and then the pool is sealed with a lid. After this, a 500 meter long straw is poked through the lid and filled with water. Let's say that the straw is very thin and the total amount of water inside the straw weighs 10 grams. Now the scuba diver would experience about the same hydrostatic pressure as if he was 500 meters deep in the ocean, which would kill him without proper equipment. This just does not make any sense to me. [link] [comments]  |
| What vector space does the elements of gauge groups act on? Posted: 02 Sep 2018 04:05 AM PDT On Wikipedia and other places, I can read that the standard model has three gauge groups, U(1), SU(2) and SU(3), for electro, weak and strong forces. These groups are represented by matrices, but nowhere can i find what vector spaces these group elements act on. [link] [comments]  |
| Why does turbulent flow cause more erosion than laminar flow? Posted: 01 Sep 2018 04:37 PM PDT I'm studying manufacturing processes and while calculating pouring velocity for a molten metal, some books mention that besides the fact that turbulent flow causes splashes while pouring metals in a mold which translates to wasted material, they erode the mold internal surface at a faster rate than pouring it at lower speeds. Why!? Many books mention it, but none explain why. I imagine it to be because the particles bounce around the mold rather than forming an insulation blanket characteristic of laminar flow. But I would like an answer that doesn't originate inside my head. Thanks. [link] [comments]  |
