| Posted: 08 Jun 2020 04:00 AM PDT Statistics isn't what you think it is! With a career in statistics, the science of learning from data, you can change the world, have fun, satisfy curiosity and make a good salary. Demand for statisticians is on the rise, and careers in statistics are consistently on best jobs lists. Best of all, statistics applies to just about any field, so you can apply it to a wide range of personal passions. Just ask our real-life statisticians to learn more about the opportunities! The panelists include:

| How does the energy of a nuclear fusion reactor scale according to its size? Posted: 07 Jun 2020 11:19 PM PDT Does it scale according to volume? For example, if you have a reactor that fits a volume X of hydrogen, and another that fits 10X, would the energy generated by the second be 10 times the energy produced by the first one? Or does it scale exponentially or by some other factor? (assuming the reactors have the same efficiency) [link] [comments]  |

| How successful is social work and assistance in reducing poverty in the long term? Posted: 08 Jun 2020 04:12 AM PDT What is the effectiveness of social workers and assistance in reducing poverty rates Hi everyone i want to ask social sciences what the effectiveness of reducing poverty is. Is this a dream or is there evidence to back it up [link] [comments]  |
| Blasius Boundary Layer approximations still apply if turbulent at trailing edge? Posted: 08 Jun 2020 07:45 AM PDT I was looking up the blasius solutions, but I can't think of how to generalise the Blasius approximations if the fluid boundary layer only transitions to turbulence(approximately) at the trailing edge. As someone with little knowledge on this subject, what I think is blasius approximations for skin friction coefficient should still apply, as past the trailing edge where turbulence occurs does not have "skin" to apply friction. However, I do not know how to show this rigorously. [link] [comments]  |

| Are there planet systems that orbit other objects? Posted: 08 Jun 2020 06:14 AM PDT I was wondering if there are systems that have planets which orbit other objects. For example if there is a system where other planets display similar behaviour to a solar system where there are a few planets somewhat close to each other that orbit an object, but instead of having a star as the centre it's something else? Maybe a bigger planet with enough gravitational pull (would that make the other planets its moons and the main planet just a rogue planet?) to be considered its own system. If there are, what are they called? [link] [comments]  |

| A dumb question about roundabouts and rods. What would happen? Posted: 08 Jun 2020 05:43 AM PDT Lets say someone had a really long rod and a roundabout and they made the roundabout spin at a speed close to the speed of light. Then they held the rod out away from the roundabout whilst on the roundabout. The other end of the rod would be moving around the roundabout at a faster speed than the speed at which the roundabout is spinning. Since the roundabout is spinning at a speed close to the speed of light one would think that the other end of the rod would be moving faster than the speed of light but this is not possible. So what would happen to the rod and the roundabout assuming that there is no atmosphere, the rod is indestructible and the person holding the rod is incredibly strong and and is stuck to the roundabout?

| Posted: 08 Jun 2020 05:04 AM PDT I am thinking for example dental lasers for cutting gums, or lasers used in surgery for cutting. Does their radiation and the temperature change only reach the nearby area they scorch? Do their effects reach any surrounding tissue other than the area they "sear"? And on the other side lasers used in dermatology that don't directly cut the skin, but somehow work on the deeper layers. One example are the YAG lasers which seem to be used for both things, some sear the tissue directly and some don't... [link] [comments]  |
| What skin flies (or insencts similar to flies as an anatomy) have ? Posted: 08 Jun 2020 03:43 AM PDT For instance, ants,cockroachs etc. have chitin. So what is it for flies ? [link] [comments]  |
| Why do you see a sort of “motion blur” in real life? Posted: 08 Jun 2020 03:28 AM PDT Sounds kinda stupid but I couldn't find an answer on google as "motion blur" will always turn up something about photography. Basically, what I'm curious about is the phenomenon when there's a dim source of light in a dark setting (like using a phone in a dark room), any fast movement always translates to a weird trail of light behind the source. Is the light being momentarily burnt into your retina or is something else happening? [link] [comments]  |
| How much of the payload in a nuclear device is actually fissioned/fusioned upon detonation? Posted: 07 Jun 2020 09:12 PM PDT I assume that the few nanoseconds after detonation of a nuclear device would instantly spill the payload out into a larger volume (I could definitely be wrong here). For how long is the payload still fissioning/fusioning after detonation? I'm curious to know how much mass is released as energy. [link] [comments]  |
| Why does yelling damage your larynx? Posted: 07 Jun 2020 08:44 PM PDT I tried to find a more specific answer with a search, but instead of telling me why... all of the results simply talked about the fact that it does. [link] [comments]  |
| Posted: 07 Jun 2020 08:16 PM PDT I know that galaxy arms are essentially density waves with stars moving in and out of the wave as they orbit around the galaxy centre. This part makes sense to me. The arms are brighter than the areas between them, and arms being brighter means that there are more stars and is therefore more dense. However, I don't understand how this density wave is stable. A common analogy to explain galaxy arms is cars slowing down to look at an accident on the side of the road. There is always a clump of cars near the accident, but cars constantly move into and out of the clump. I don't like this analogy because I would think that stars would speed up, not slow down, as they approach the density wave because of the gravitational attraction between that star and the density wave. Similarly, I would think that a star moving out of the density wave would slow down for the same reason. If this were the case, I would expect galaxy arms to quickly fade into a more uniform disc, but we know this to not be the case. What am I missing here? [link] [comments]  |
| Are there different varieties of viruses under the COVID-19 virus? Posted: 07 Jun 2020 04:48 PM PDT When I see the statistics, in some regions, the mortality rate is high and in other regions, it's low. What's the reason behind this? [link] [comments]  |
