Today I Learned

[Astronuc]

TIL that electrical circuits on boat docks do not necessarily have GFCIs. While many state governments do not require it, but it is just common sense to have GFCIs on any electrical circuit near water. It shouldn't be necessary for governments to mandate safety practices - but apparently it is.

TIL that the recommended daily calorie intake for a male rower in an ocean-going solo rowboat is 4,000, although apparently one can get by with 2,700 in the form of 2 breakfasts + 2 dinners + grains, muesli, powdered drinks.

Today I learned that a Twinkie has more energy pound for pound than TNT. Twinkies just do not release it as fast.

This is so sad, I remember when "common sense" was more than just a John Prine album.

Today I learned that Julian Assange tricked the US gvt into forcing down the plane of the President of Bolivia in an attempt to capture Edward Snowden. Assange discussed the fake "plan" on an unsecure line.

I wonder: how far across the water can disabling shocks go given whatever common power sources are found on boat docks? I would have thought just a few (less than 10) meters but the article seems to imply much more.

Today I learned that during the Martian summer atmospheric concentrations of Methane increase and then fall during the Martian winter. All though many geological processes could produce this Methane, maybe there is a (very) remote chance it is from microbes. After all, microbes seem to generally have faster metabolisms in warmer environments.

Yep. The species called: open the window.

I learned how to replace the backcover of a Huawei P6.

An "old" phone lying around the house had one of the corners "detached" from the main body after it was dropped.
So I got around fixing it.

I also learned that its normal that it heats up (a lot) when doing intensive stuff.
I don't get why they didn't fix it though, it's quite disconcerting with the occasional story of exploding batteries.

[Tobias Funke]

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.

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

 

[jim hardy]

The article says nothing about education level.

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.

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.

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

somebody will surely find that statistic.

According to ABC, Clinton and Trump have the same appeal to college-educated whites. https://www.washingtonpost.com/poli...top-table-main_poll0522-1201am:homepage/story

That's as close as I could come.

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

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.
