Oh gosh, no! Count me among those who greatly dislike pie charts in almost every context.

I disagree. I highly appreciate @alterom's perspective and clear elucidation, and think the discussion has been fantastic.

Sure, we could speculate about his true unstated reasons for marking wrong my answer.

I highly doubt the science teacher marked me wrong for "dumping", though. He had every opportunity to explain that to me after I got my exam graded and I asked him about it. Then he had the opportunity to explain that face-to-face with my parents. He did not do so. He said that while I got the answer right, he was "mad", thus the mark against.

Besides, notecards were not allowed for any part of the exam, and I wrote my answer from memory. I think it was clear that I knew my stuff pretty well and was not "dumping" a bunch of bullshit onto the science teacher.

There was no indication before taking the exam that I would be punished for hurting his apparently-sensitive feelings while giving the correct answer (as he agreed I did). If there were, I certainly would have chosen a different medium for proving my command of the material.

> From grade school on, you are graded on whether or not the grading authority likes the results you got.

I took an exam in a high school science class where I answered a question with the textbook's definition exactly as presented in the textbook, complete with the page number the definition was found on. I knew a bit about the topic, so I then cited outside scientific sources that explained why the definition was incomplete. There wasn't enough room to complete my answer in the space provided, so I spiraled it out into the margins of the exam paper.

My teacher marked my answer wrong. Then crossed that out and marked it correct. Then crossed that out, and finally marked it wrong again. During parent-teacher conferences, the science teacher admitted that even though I answered the question with the exactly correct definition, my further exposition made him "mad" (his word), and because he was angry, he marked it wrong.

Also, for what it's worth:

> Some people have characterised Tangier’s way of speaking as ‘Elizabethan’ or ‘Restoration’ English, but that’s nonsense. Languages aren’t static and the Tangier dialect has changed a lot because of its isolation. It’s a distinct creation of its own," Shores said.

npongratz··on The Origin of the Pork Taboo
> As many people speak of this difficulty to evolve and change their diet, I have come to theorize that people have a deep seated cultural need for sacrifice -- something must die for their meal to be legitimate.

Of course something must die, but it's not because of culture. Even the most devout vegan would surely concede that the plants they eat must die in order to render sustenance from them. The reality we live in, even if we don't like it, is the simple fact that something must die for us to continue living.

npongratz··on Kissing moons may explain why Earth's moon is so large
My understanding is that the composition of each body is different. There's the obvious: More ices and liquids comprise Ganymede, possible since Ganymede is so distant from the Sun. And the not-so-obvious: Mercury is anomalously dense due in part to (likely) having a disproportionally large core of iron and nickel.

I find Wikipedia's discussion about Mercury's density in contrast to Earth's fascinating [0]:

> If the effect of gravitational compression were to be factored out from both planets, the materials of which Mercury is made would be denser than those of Earth, with an uncompressed density of 5.3 g/cm3 versus Earth's 4.4 g/cm3.

The Neptune-Pluto gravitational resonance is pretty neat. Wikipedia has a nice listing of other orbital resonances in the solar system:

Likely gravitional:

For what it's worth (nothing, just interesting to note): Ganymede is larger, and less dense. Mercury's mass is more than twice Ganymede's.
npongratz··on Jeep owners fed up with in-car pop-up ads
I see two major differences to the mass advertising of yesteryear (which, similar to you, I have also lived through):

1) The psychological manipulation inherent to all advertising has shifted from diluted, mass manipulation to pinpoint-accurate, targeted manipulation right down to the individual level, with impunity via plausible deniability.

2) Advertising is a major distributor of malware, with the ability to target anything with a chip.

Given either one of the above, I absolutely cannot trust any advertising delivered via modern technology. Since we have to contend with both issues, I view modern advertising as one of greatest threats to my mental health and individual sovereignty that exists in my day-to-day life.

I can just hear the pitch to auto CEOs and "business development" execs:

"... now with full self-driving! Where your captive audience can't use the safety excuse for avoiding your very important and lucrative propaganda!"

The AM and FM radio ads cannot surveil you like the GPS- and cell-enabled (and forced) in-vehicle advertising systems do.

> This is some Black Mirror type dystopian vision of the future for me.

Indeed. I always assumed this was the impetus for FSD: these vehicles confine the most captive audience, so they will be a surveillance/advertising gold mine.

Quite an understatement:

Reagan fired federal employees. Are the striking dockworkers employees of the US federal government?

npongratz··on Intel is trucking a 916k-pound 'Super Load' across Ohio to its new fab
Don't know what to say -- the page returns 200 for me, from a couple different networks and different devices and different browsers, yesterday and today. I definitely agree, though, that the archive services show 404.
npongratz··on Intel is trucking a 916k-pound 'Super Load' across Ohio to its new fab
> It's split up into 18 separate loads

TFA suggests it's not split up:

> Intel will put a 916,000-pound "super load" on the road in Ohio on Wednesday, for a trip that will cover approximately 150 miles in nine days and snarl traffic for over a week...

> Four of these loads, including the one hitting the road now, weigh around 900,000 pounds — that's 400 metric tons, or 76 elephants.

> Intel's 916,000-pound shipment is a "cold box,"...

EDIT: Further information in the ODOT advisory detailing the schedule of this one shipment confirms 916k pounds is not split among multiple loads:

https://www.transportation.ohio.gov/about-us/traffic-advisor...

> This is the twelfth of nearly two dozen "super loads"... This load... measures approximately 23’ tall, 20’ wide, 280’ long, and weighs 916,000 pounds.

npongratz··on Some people with insomnia think they're awake when they're asleep
I proved a topology theorem in a dream once.

Before I went to sleep, my inability to prove it had been bugging me all day long, and I suspected it'd be featured on the next morning's (way too early) final exam for my university course. I solved it in my dream, woke up, wrote on my whiteboard what I remembered and sure enough, it was correct. I worked it a few more times to cram it into my memory before running to my exam.

To my great delight, the ability to prove that theorem was featured heavily in one of the exam's questions, and helped me do quite well on the exam overall.
