I suggested this in post 11, he wants something different. -
Dale replied to the thread Undergrad Simplified Special Relativity: Looking to get roasted on this.Then you need to branch out beyond your teachers. The other possible approach is to just learn relativity yourself. In the course of...

Dale replied to the thread Undergrad Simplified Special Relativity: Looking to get roasted on this.In all honesty, there is no point in trying to argue your case. As I showed in post 16 you have two mutually contradictory claims, so...

Dale replied to the thread Undergrad Simplified Special Relativity: Looking to get roasted on this.So this combination is really not possible. You cannot both have conflicting/contradicting assumptions and no contradiction with...

Dale replied to the thread Undergrad Simplified Special Relativity: Looking to get roasted on this.In general, a mathematical framework has a large set of statements that are true in the framework. Usually, you can take some small...

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...

No, they show a lot of deformation. It is impossible to say without measurement how the volume has changed.

While the images of carbonated mineral water are highly informative, note that even 'still water' can have a lot of dissolved gas (air)...

I don't expect "infinite controls". I would just encourage you to be reasonably careful about your experiment before you expect good...

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...

Dale replied to the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?.This is no paradox, it is standard experimental science. Well-considered and carefully-executed controls are critical to good...

Some of those photos show a LOT of loss of volume. IMO, that much shrinkage is hard to explain. And it is very pronounced in some...

Dale reacted to Chestermiller's post in the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property? with Like.
The volume expansion from water to ice is an intrinsic property of water specifically under the constraint of negligible confining...

I froze a plastic bottle full of water (as near to mo air as I could manage) and put it in a bowl of water. It floated: And a crop of...
