SUMMARY
This discussion revolves around the concept of daily learning, where participants share various facts and insights they have recently discovered. Key topics include the woodworking technique "oyster veneering," the mathematical fact that 23! equals 25,852,016,738,884,976,640,000, and the medical terms "hyperacusis" and "diplacusis." Participants also touch on humorous observations about life, such as the impact of television on weight and the emotional sensitivity of Barn Owls.
PREREQUISITES- Understanding of basic mathematical concepts, specifically factorials.
- Familiarity with woodworking techniques, particularly historical methods like oyster veneering.
- Knowledge of medical terminology related to hearing, such as hyperacusis and diplacusis.
- Awareness of cultural references, including the significance of historical events and figures like Muhammad Ali.
- Research the historical context and revival of oyster veneering in woodworking.
- Explore advanced mathematical concepts related to factorials and their applications.
- Investigate the medical conditions hyperacusis and diplacusis, including their causes and treatments.
- Learn about the emotional behaviors of animals, particularly Barn Owls and their sensitivity.
This discussion is beneficial for woodworking enthusiasts, mathematicians, medical professionals, and animal behaviorists, as well as anyone interested in the quirky facts of daily life.

Nonsense, 22/7 has an infinite decimal expansion, whilst by the fundamental theorem of engineering it's trivial to see that ##\pi## must in fact terminate.

When you say "basis", do you mean "base", i.e.$$mfb said:
1 \times \pi^1 + 0 \times \pi^0 \quad ?

Yes.
German uses "basis" both for vector spaces and bases of numbers, forgot that English does not.

I see that the present Indiana General Assembly is only recapitulating its long and proud intellectual tradition:

@hutchphd Indiana is # 12 in a list of states for deaths per 100M from Covid. Not enviable.

We have both lots of old people and lots of the "less important" people. Actually the vaccination program here has been surprisingly good (I got my second Moderna two weeks ago at the Kroger three blocks from my door...I am 69) so I am not personally very worried. Good thing I am computer literate (and white) of course.

Pi, shmi. I like e the base of the natural logarithms. And its first digit is to too, two to, tutu, 2 also.

TIL about Roman dodecahedrons. They have been found in many places, so they were clearly a thing - but no one knows why.

That is completely clear to me. It is a "Knochen". Sorry, I have no idea how to find the English word for it.mfb said:

I always like when we find mysterious ancient tech. It keeps us humble.mfb said:
I also like the line from the wiki
”A Roman icosahedron has also come to light after having long been misclassified as a dodecahedron.”
