In the news media, reports to the extent to which kids are manipulated is minimal from earlier years of the internet and social media when some cases drew attention. At least it appears that way. And yet, folks did draw attention to their younger kids, who had no say in the matter, by posting...

A while back ( 10 years or so ) someone told me their child had to delete their account on Facebook due to being under 16, maybe under Biden. Under Trump, the tech social media switched sides so that might not now be as much of a concern. But a lost account is lost revenue. Some oversight...

Here is a representations of 2 spheres, one 9% larger in volume than the other due to phase change of water from liquid to solid.

One can calculate the radial increase from the volume boost due to the phase change. For a container of stretchy material that expands willingly, ( such as thin rubber balloon ) A 9% increase in volume translates into a 2.9 mm difference from initial inner radius to final. The outer radius...

And others have lost their shirt on failed stock purchases. Movement from one grouping to another is not disallowed for any one individual. The statistics apply to the group behavior, and can attempt to predict overall future trends from past data. If based on only wealth, the economic...

Very good questions I must admit, and not without merit. One would tend to think that the 'pressure' of the ice would shrink the bubble size according to PV=nRT, hence the thermodynamic reference. Consider an arch or dome under external load. The material of the dome becomes stressed and resists...

Isn't that where light bends when passing from one medium to the next?

the answers that you have received are coming from the belief that your experiment is as you say it is and nothing else. There is no bias against the experimental investigation as outlined.. A valid experiment does not rely upon I think it is so, therefor it must be. A valid experiment relies...

The water can dissolve a quantity of gas based upon its temperature and the external pressure. If the pressure in the liquid is decreased, some gas will come out of solution as bubbles. Water turning into Ice is purified by expulsion of dissolved gases. This happens at the boundary of ice...

The water in the pipe freezes from the wall inwards, so there is a cavity of liquid surrounded by ice. As long as the water does not freeze completley in a couple of spots sectioning off a portion with plugs, the copper pipe can expand along its whole length and radius. Once the plugs are...

Quite sure the wall thickness of a plastic bottle is not uniform as it is blown plastic. The 'oval' shape of the frozen water bottle will deform where it is thinnest thus expanding outwards from the ice pressure. The thicker part will pulled inwards. Much like blowing up a balloon between two...

That is frigin hilarious! No doubt I will still be chuckling several days from now. May we have found the actual reason for tinnitus, people become sensitive to the background gravitational waves and can hear them vibrating the ear drum. :wideeyed:

Previous answer was more to the point for a realistic earth, with the error given here of correct magnitude. This answer here though is incomplete for scaling in that for a finite surface body such as the earth, an increase in land mass area will decrease the ocean area, and vice-versa...

The water cycle includes atmospheric evaporation and condensation, so I suppose that can be called a natural distillation. The adjective 'natural' does not imply purity in the sense as it is used here. The atmosphere contains contaminates from both the natural environment as well as from human...

The problem is the circle packing problem. How many circles can fit is a specific area? For a circle of radius r, 1 circle will fit in a square of side dimension r, or within an equilateral triangle of side length r. packing density - 0.785. Within a hexagon of side length r, the density...
