[Lex Computer & Tech Group/LCTG] why does ice float

[Michael Alexander]

>From Peter Shaw:“Regarding the abstract, ‘The presence of a maximum in density is one of the well-known anomalies of water’
“What are some of the other anomalies?”
One of the others is an unusually high self-diffusion rate of H20 molecules within ice (solid H2O).  
Another, related to the one Peter quotes, is that the maximum density occurs when water is liquid, not when it has solidified.

All,
All of this just once again brings back the famous graffiti on the back of one of the wooden chairs in the original incarnation of the Legendary MIT Lecture Hall -- 10-250 [Maclaurin Building -- Huntington Lecture Hall  ---  for those unfamiliar with MIT Campus-speak]The Hall dates to the era of the completion of the original Cambridge Campus circa 1920Carved into the curved wooden back side of the chair [on the side facing the next row behind]:
 [pair of original chairs from the MIT MUseum collection]


Science is a Communist Plot
Plotting is a Communist Science
There is no known precedence [then] and subsequently the chairs have all been replaced by cushioned chairs -- so its reality is lost to history

This reminds me of an interchange in my introductory calculus course.
Professor:  Why does 1/x go to zero as x goes to infinity?

Class:   [stunned silence]
[more silence]
Professor:   Because it waants to!

As a  degreed chemist, I don't need to look this one up. 

  

But the Dad Answer looks a lot like ChatGPT made it up.
