What explains the following phenomenon:
Fill a basket about halfway with straw, add a few eggs, fill the rest of the way with straw such that the eggs are approximately in the center of a basket of straw. Now, shake the basket. One would expect the eggs, being much heavier (denser) than the straw would "gravitate" to the bottom of the basket; however, they rise to the top instead.
I came across this in a real-life experience and remembered the above phenomenon from one of my prehistoric science classes, but forgot the explanation. — 2606:A000:1126:28D:20D1:2886:5F71:22E5 ( talk) 15:45, 20 January 2019 (UTC)
OK. I just have to ask. Why would anyone want grapes to stay at the bottom of a container of tobacco? -- Guy Macon ( talk) 22:29, 20 January 2019 (UTC)
Certain emotions e.g. joy, sadness do not seem to necessitate a "cognitive", or "propositional" (I think that's right) component to them: they don't have to be "about" anything. However, others, such as anger or surprise, seem to.
I didn't see anything about this on the solitary confinement page. I just want to know if there's any data about individuals being isolated and how long they lasted before they experienced any mental issues. Sensory deprivation studies would be the extreme version of what I see.. I'm just looking for data in regards to solitary confinement with little sensory input. 50.27.72.253 ( talk) 18:05, 20 January 2019 (UTC)
Why does my ear wax come out brown but then go yellow after rolling it? 80.2.22.165 ( talk) 21:49, 20 January 2019 (UTC)
