| What determines where the poles are on a ball magnet? Or a bar magnet? Posted: 03 Apr 2022 05:36 AM PDT On a bar magnet, one end is north and the other is south. What exactly determines which end is which? What about a sphere magnet? They would be on opposite sides obviously but what determines where the north and south are on something that doesn't have ends? Couldn't really find an answer from google but I probably don't know what to search for. Thanks a lot in advance. In a debate with a flat earther and I need some ammo from smarter people. EDIT: Thanks guys, I learnt a lot of interesting stuff about magnets from this. Unfortunately, the flat earther I was debating called me a sheep and scuttled off into the internet undergrowth when I asked how a flat, stationary earth generates a magnetic field. All he did was link a video of Eric Dubay blithering incoherently before crawling away. [link] [comments] |

| Is there a consensus on how cannabis impacts the brain in the long term? Posted: 03 Apr 2022 07:35 PM PDT I always read the research on acute effects, which while useful, I find to be less personally important than long-term effects. This is because I use it usually in contexts where I'm okay to have some deficits in memory etc. However, is there good research on the long-term effects? I'm looking to the literature now but wanted to ask too because it would take a while to tease apart the good and bad research, before integrating the info into a clear picture. [link] [comments] |
| Why is a french curve set 'sufficient' for drawing curves? Posted: 03 Apr 2022 01:25 AM PDT The instrument in question is this: https://en.m.wikipedia.org/wiki/French_curve It seems to be based on euler curves, and its use is to take a number of points, find the part of the toolset that best lines up with some of them and using that as a ruler. What I can't wrap my head around is sufficiency. There should be a massive variety of curves possible. Is the set's capabilities supposed to be exhaustive? Or merely 'good enough'? And in either case, is there some kind of geometric principle that proves/justifies it as exhaustive/close enough? [link] [comments] |
| Is ear connective tissue genetic? Posted: 03 Apr 2022 07:34 PM PDT I'm wondering if the connective tissue on the lobe of an ear is genetic or if it can be caused by an injury and be temporary. Specifically the ear of the man in this photo: https://i.pinimg.com/564x/e9/33/07/e933074cb684a43b4d59013c6a6cb0e9.jpg I've never seen that kind of ear lobe before. Any help would be appreciated!

| What is "regularized" gradient descent? Posted: 03 Apr 2022 02:43 AM PDT A particular implementation of gradient descent that I've encountered right now takes what looks like a normal formula for the algorithm, but then it adds a mysterious new term at the end for "regularization". I don't really understand what it does and how it works. As far as I can google, regularization is a limitation on models, not on optimization algorithms -- I'm not really sure how to even apply regularization techniques to the concept of gradient descent. Could someone help? [link] [comments] |
| How do nerves communicate to the brain.? Posted: 03 Apr 2022 01:17 AM PDT I have some understanding of electronics such as multiplexing signals and converting multiple analog inputs to a single data stream that an mcu can decode. Do nerves work similar? Like how do the many touch sensors of a finger have a unique location that the brain can identify. In a mechanical system it might be the individual Id of a sensor is embedded with the signal and you can map that in software. From what I understand thousands of nerves for touch, heat, etc somehow communicate via a much smaller number of nerves traveling to the brain. This is the part I'm trying to understand the most, how is the body multiplexing demultiplexing those signals? [link] [comments] |
| Posted: 02 Apr 2022 11:34 PM PDT How do ants, especially the ones commonly found in peoples houses, find their food sources? Do they have a sense for it or just keep roaming aimlessly until they find something and go back to the colony to tell the good news? [link] [comments] |

| Posted: 02 Apr 2022 07:24 AM PDT When on T4 supplementation, because of Hashimoto Thyroiditis, most people just stay on the same dose for decades. But since the thyroid is shrinking, and the little job it was doing is inexistent now, by logic, people should increase the dose as the time passes. But it doesn't happen most of the time. Why?
