Graduate Geometry of Bluetooth Field
I am curious about an experience using earbuds with a smart phone music app. With smartphone on the porch, I was roaming the garden listening to music on a pair of earbuds. At a some distance from the smart phone the signal began to break up into a staccato of brief fragments which were just...- Twodogs

Graduate Information theory via knot theory
Knotty Knits are Tangles on Tori Shashank G. Markande1 and Elisabetta A. Matsumoto2 https://archive.bridgesmathart.org/2020/bridges2020-103.pdf This is a less abstract & more hands-on approach that does note the mechanical responses of various knit patterns.- Twodogs

Graduate Information theory via knot theory
It is interesting to see what the math might look like, thanks. So, would increasing the complexity of G be equivalent to adding symbols to your alphabet, increasing bits/symbol? I am thinking that your "topological channels" is kindred to communication channel rather than river channel. I am...- Twodogs

Graduate Information theory via knot theory
"that the major tenets of information theory can be established through knot theory" Well, I remember who made this statement and it was Chris Hillman who was post doc at University of Washington. I find on checking that he was a contributor to Physics Forums until sometime just before 2022. My...- Twodogs

That would be helpful, thanks. This was 40 years ago and I have lost touch. I do remember the comment though.- Twodogs

Graduate Information theory via knot theory
A mathematician friend told me that the major tenets of information theory can be established through knot theory. Is that the case? Thanks.- Twodogs

Undergrad Singing Crystal Wineglass -- Does the wine mass determine the pitch?
Reading about resonance as an emergent phenomenon and wandered into chemistry "Resonance is a consequence of the valence bond (VB) theory." I regret lack of clarity. I know you can not reference any AI sources, but not clear about posting article from say Quanta Magazine.- Twodogs

Undergrad Singing Crystal Wineglass -- Does the wine mass determine the pitch?
Reading about resonance seen as an emergent and ubiquitous phenomenon. Interesting. Chemistry for example, "Resonance is a consequence of the valence bond (VB) theory." What are the protocols for posting URLs to Physics Forums?- Twodogs

Thanks all for input. Time to empty the wine glass.- Twodogs

Undergrad Singing Crystal Wineglass -- Does the wine mass determine the pitch?
Thanks for going through that step wise. The mass of the longer guitar string a good example. In the wine I am thinking that the sound pressure waves, must be concentric, go to the center and bounce back. But the same mass in a glass with lightly larger diameter would not produce the same tone...- Twodogs

Undergrad Singing Crystal Wineglass -- Does the wine mass determine the pitch?
Well, I would surely like to experiment with an acoustic probe measuring period of pressure transients in wine. Apparently the wine in glass system I describe is analogous to the period of a weight cycling on a spring. The more weight the longer the period. I would like to know exactly how the...- Twodogs
