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.
NEXT STEPS
  • 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.
USEFUL FOR

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.

Today I learned that Trump voters are more educated and have 20% higher incomes than Sanders or Clinton voters.

That doesn't surprise me all that much, but that's only because I've read the chapter in Lies My Teacher Told Me about the myth that educated people are somehow more liberal or tolerant (the specific example was regarding the war in Vietnam). I was a little surprised then, even thought in hindsight maybe I shouldn't have been.

As for what I learned today, it's to be more careful when following recipes.

it grazes the subject in next to last paragraph

Likewise, although about 44 percent of Trump supporters have college degrees, according to exit polls — lower than the 50 percent for Cruz supporters or 64 percent for Kasich supporters — that’s still higher than the https://www.census.gov/hhes/socdemo/education/data/cps/2014/tables.html , or the 29 percent of American adults overall, who have at least a bachelor’s degree.

[Emphasis mine.]

The article says nothing about education level. [As in direct comparison of Trump voters with Clinton or Sanders voters.]

By golly, you're right. I couldn't find statistics about degrees for Clinton-Sanders voters.

I did read that, but it's not a direct comparison of education level between of Trump voters with Clinton or Sanders voters. Rather it's a comparison between Trump voters and voters of other republican candidates, and also some US census data thrown in.

Democrats hold advantages in party identification among blacks, Asians, Hispanics, well-educated adults and Millennials. Republicans have leads among whites – particularly white men, those with less education and evangelical Protestants – as well as members of the Silent Generation.

I believe it is true that the higher the level of education, the more likely one is to be a Democrat.

edit noted.
yes, that's why i said "graze..."

somebody will surely find that statistic.

I thought that as well, but the data in that article don't exactly support it. It seems to be just barely true today, but that seems to be fairly recent. During most of the past 20 years Rs were more likely to be college educated. The graphs are not constructed for this purpose, so its confusing. There were more college educated people voting Democratic, but more likely that a Republican be college educated than a Democrat.

In most of those years
P[ College educated voter votes D ] > P[ College educated voter votes R ]
P[ Republican is college educated ] > P[ Democrat is college educated ]

this is largely because
P[ Voter is D ] > P[Voter is R]

The D's have a big advantage in post-grads. Maybe that's where the impression comes from. Doctors, lawyers, and finance people shifting to D. Not surprising, as the D's policies increasingly favor the well-to-do "yuppie" class.

But the D's also have an advantage in no-college folks, so it isn't clear that education is correlated with Dness. If it is, it isn't much.

Recall that this is registered party members. The situation with the general public is surely different. Maybe that's where the impression comes from. Registered Democrats and those who vote Democratic are not the same group.

Thanks, this is really interesting.

Today I learned that if a dog chases a kangaroo, the kangaroo will head for water, go in, and turn and wait for the dog. If the dog comes into the water, the kangaroo will then grab it and hold it under the water until it drowns.

Today I learned that it took life 500 millions year to learn photosynthesis.

Well, I learned photosynthesis in elementary school.

Today on my trip to the Hoover Dam I learned that it took only 5 years to build the dam and power plant! I am sure an equivalent could not be built as fast 'today' with so many safety regulations and environmental protection jazz...

That's why there's a quote "... do something like Hoover Dam" I don't know the exact words.
And the chief engineer, wait googling... Sorry can't find him :smile:. But I watched how Hoover Dam built in Nat Geo. And building the dam took many casualties. But it's done. The dam was finished anyway. And we can compare the chief engineer (which I can't find the name) to Leslie Groove (Manhattan Project, Pentagon).

"Even before Congress approved the Boulder Canyon Project, the Bureau of Reclamation was considering what kind of dam should be used. Officials eventually decided on a massive concrete arch-gravity dam, the design of which was overseen by the Bureau's chief design engineer John L. Savage." (Wikipedia)

Ah, him. Yes. He was a very tough person, from what I watched in Nat Geo. Many casualties, but nothing couldn't stop him.

Isn't that cool? I do that for my normal shoes, but I also wear shoes with really long strings, which forced me to tie them up military style. The way I tie them now makes the laces look like a big flower :partytime:
